Hi,

I want to change the current decimal separator in the property cells of my app. For the moment the separator is ’,’ (french Windows XP). I want to change it and have ’.’ instead.
The language in the ressources is set to English (US - 0x0409) but the separator is still ’,’.
Same thing if I make a call to SetThreadLocale(MAKELCID(0x0409, SORT_DEFAULT));.

Do you have a way to change this separator in the cells ?

Thanks in advance.

Hello,

Just like a column can be activated and deactivated, can a row be activated and deactivated.
I would like to add a filter that hide rows that meet search critirias.
I don’t want to have to register and unregister items.

Thank you.

Hello,

If you could have it in a month or two that would work for us.
Any longer and we would have to develop it ourselves.
Let me know.

Thanks.

Dear Support Team,

First of all, let me wish you an happy new year !

I was looking for forcing CLEARTYPE_QUALITY in our application and saw that all the relevant code was commented out in CExtPaintManagerOffice2007_Impl::CreateDefaultFont().
Is there any reason for ? Is it work in progress ?

I then declare my "Paint Manager" based on your code and all of your "100% from scratch" GUI is working great with ClearType but not basic controls like CExtLabel, etc...

What would be the best way to go :
1. Override all controls that I use for methods like CExtLabel::OnDrawLabelText, CExtButton::OnQueryFont, ... ?
2. Override OnInitDialog or OnInitialUpdate for all controls like static, button, etc with a generic method based on fonts from PaintMnager?
3. Set the correct font for each control in OnInitDialog or OnInitialUpdate ?

Best regards,
Fabien.

Dear Team Support,
Dear Sergiy,

Any hints to my 3 questions ?

Regards,
Fabien.

Dear Sergiy,

I derivated the CExtPaintManager and add a property flag to control the ClearType effect (based also on m_bIsWinXPorLater).

I add to implement the following methods :
- virtual HFONT CreateDefaultFont();
- virtual HFONT CreateCaptionFont();
- the 2 static functions needed by CreateXXXFont methods.

At the end of each OnInitialUpdate (CFormView) or OnInitDialog (CDialog), I call an internal method of my paint manager which check what kind of font is set to all my controls (normal or bold) and replace it with the correct font of my paint manager.
So, all the code is placed in my paint manager and it’s not so complicated to handle it.
Would you have a better method than doing this way ? (Question 1)

Everything is working great (or at least 99% of it) ; in fact, sometime, It doesn’t use my font in CExtDateTimeWnd (when the control is created dynamically). Any hint ? (Question 2)

When I play with the lfHeight attribute of LOGFONT (+ some ressources tweaking at run-time in Create...), everything is painted correctly except the CExtStatusControlBar which is not "height" enough. Any tip for it ? (Question 3)

Best regards,
Fabien.

1. This is an acceptable way.

2. We discovered that the custom controls, derived from CWnd, do not respond to the WM_SETFONT message automatically. The WM_SETFONT and WM_GETFONT messages simply do not work. So we had to handle these massages manually and store the font handler inside all our custom controls, such as the CExtDateTimeWnd. The latest library version 2.63.3, available from the Download page, is already free from this bug.

3. You can change the height of the status bar using the CStatusBarCtrl::SetMinHeight() method:

CStatusBar & wndStatusBar = . . .
    wndStatusBar.GetStatusBarCtrl.SetMinHeight( 50 ); // sets the height of 50 pixels

Dear Support Team,

Do you think I should go the 1st way ? override all controls painting methods ?

By the way, it seems that when you use an higher lfHeight, the bottom status bar is not updated correctly. What do I miss ?

Regards,
Fabien.

I have a compound property value in a property store that is specified below:

CExtPropertyValueCompound * pValueCompoundColorFill =
        new CExtPropertyValueCompound("Fill Color" );
    pValueCompoundColorFill->DescriptionSet(
        _T("Specifies the fill color of the object")
        );
    CExtGridCellColor * pColorCellCompoundFill =
        STATIC_DOWNCAST(
            CExtGridCellColor,
            pValueCompoundColorFill->ValueDefaultGetByRTC(
                RUNTIME_CLASS(CExtGridCellColor)
                )
        );
    
    pColorCellCompoundFill->m_PackedColor.SetColor(IsNoFill() ? COLORREF(-1) : GetFillColor() );
    pColorCellCompoundFill->SetMode( CExtGridCellColor::eRGB );
    pColorCellCompoundFill->m_bEnableButtonDefaultColor=true;
    pColorCellCompoundFill->m_sBtnTextColorDefault="No Fill";
    pColorCellCompoundFill->m_clrDefault = COLORREF(-1);

When I click the No Fill button in the pop up color selection OnPgcInputComplete is not fired and when I extract the value from the property store (pColorCellCompoundFill->m_PackedColor.GetColor())the value is still the default color not COLORREF(-1)

Can you point me in the right direction.

Regards,

Eddie

Thanks for your reply, I have done this and am getting the OnPgcInputComplete event, but how do I know that the "No Fill" button was pressed as I specifiy
pColorCellCompoundFill->m_clrDefault = COLORREF(-1);

and in OnPgcInputComplete I have

CExtPropertyValueCompound * pCompound =
        DYNAMIC_DOWNCAST(
            CExtPropertyValueCompound,
            pPropertyItem
            );
    CExtGridCell * pCellActiveValue = pCompound->ValueActiveGet();
    ASSERT_VALID( pCellActiveValue );
    CExtSafeString strPropertyName = pCompound->NameGet();
    COLORREF testClr=COLORREF(-1);
    if( strPropertyName == "Fill Color" )
    {
        CExtGridCellColor * pCell =
            STATIC_DOWNCAST(
                CExtGridCellColor,
                pCellActiveValue
                );
        testClr= pCell->GetColor();
    }

and testClr is coming out as white not COLORREF(-1)?

Regards,
Eddie

Yes, you are right. Our previous bug-fix was not complete. So we fixed this. We will upload 2.63.3 tomorrow. Please note now all the negative color values (i.e. COLORREF(-1L)) are interpreted as invalid (empty). To detect whether the cell color is valid (not empty), use CExtGridCellColor::IsEmpty().

Thanks for your help, how to I download 2.63.3?
Regards,
Eddie

v.2.63.3 is available from our website at http://www.prof-uis.com/download.aspx

This now works correctly except now when I show the property grid and set the color with
pColorCellCompoundFill->SetColor(IsNoFill() ? COLORREF(-1) : GetFillColor() );
I cannot choose the top left color in the picker which is black, any suggestions?
Regards,
Eddie

The CExtGridCellColor::m_clrDefault property is initialized, by default, to COLORREF(-1L). If you set it to a correct color value constructed using the RGB() preprocessor function, then you will should see it in the top color button of the color pop-up menu.

Here is my code for setting the default color button

pColorCellCompoundFill->SetColor(IsNoFill() ? COLORREF(-1) : GetFillColor() );
pColorCellCompoundFill->SetMode( CExtGridCellColor::eRGB );
pColorCellCompoundFill->m_bEnableButtonDefaultColor=true;
pColorCellCompoundFill->m_sBtnTextColorDefault="No Fill";
pColorCellCompoundFill->m_clrDefault = COLORREF(-1);

It is NOT the default color button that is not working it is the top left in this picture

Please find the following code in the CExtGridCellColor::OnButtonPopupMenuTrack() method:

if( nResultCmdID == 0 )
    return true;

and replace it with this

if(     nResultCmdID == 0 
    &&  clrValueFinal == COLORREF( -1L )
    )
    return true;

This should fix this. Thank you.

I get a Link error using Application Wizard and then trying to build (Debug):

fatal error LNK1104: cannot open file ’ProfUIS263md.lib’

Of course it is an error because it does not exist, but how do I create it?

Thanks,
Wes Garrard

You have to build the libraries. From the "Getting started with Prof-UIS guide":
"1. Setting Paths and Compiling

After completing the installation, you need to set up the required paths. This can be done either with the Prof-UIS Integration Wizard, or manually. The first way is simple and straightforward: Just select the check box Set Prof-UIS paths in Microsoft Visual Studio Environment Variables and click on the Next button. The second is described below.

Select Options from the Tools menu. Open Directories tab in Visual Studio 6 or open the Projects folder and, then, select Visual C++ in Visual Studio 7.0/7.1/8.0. In the Show directories for drop-down list, specify file types and corresponding paths according to the following table:
File types     Paths     Visual Studio
Include files     .../Prof-UIS/Include     6.0, 7.0, 7.1, 8.0
.../Prof-UIS/Src
Source files     .../Prof-UIS/Include
.../Prof-UIS/Src
Library files     .../Prof-UIS/Bin_600     6.0
.../Prof-UIS/Bin_700     7.0
.../Prof-UIS/Bin_710     7.1
.../Prof-UIS/Bin_800     8.0

Use the Prof-UIS Integration Wizard or Visual Studio’s Batch build (or Configuration manager) to compile Prof-UIS and its samples to any of the available build configurations. Prof-UIS samples serve on one hand as an example of how your application may look, and on the other, they should help you implement library’s features in your products."

Sorry, I found it. I failed to compile ProfUISDLL for MBCS Debug (and Release).

That does however bring up a question. Does the ProfUIS App Wizard allow for changing this to for instance ANSI or Unicode and if not how is this changed manually, say for instance to ANSI.

Thanks,
Wes Garrard

I’m trying to build a static lib with DLL MFC and no resources. I’m doing a "Static MBCS Debug with MFC DLL" build. If I remove the #define __EXT_PROFUIS_STATIC_LINK_WITH_RESOURCES line from Prof-UIS.h, I get a lot of compile errors including

error C2504: ’CExtHookSink’ : base class undefined

How do I build a static lib without resources?

SetTooltipText(int nId, BOOL bActivate = TRUE); Works with toolbar buttons. No such function that I can see in CExtCustomizeCmdTreeNode.
In addition, the OnHover for Ribbon Buttons does not display any tool tip from the string table associated with the command id.

Is there one and I just can’t see it?

Dear Andrew,

The CExtRibbonBar/CExtRibbonPage controls are able to display classic toolbar tooltips like the CExtToolControlBar window does. But these tips are not very consistent with the ribbon’s design. The super tooltip windows with caption, description paragraph, bitmap, bottom paragraph (typically displaying the Press F1 for help text) is to be appear at the end of January/begin of February. If you need toolbar like tips right now, then you should initialize them in the command manager after the command tree was assigned to the CExtRibbonBar or CExtRibbonPage control:

UINT nCommandID = ID_SOME_ITEM_IN_THE_RIBBON_BAR;
CExtRibbonBar * pRibbonBar = ... // or CExtRibbonPage
    ASSERT( pRibbonBar->GetSafeHwnd() != NULL );
LPCTSTR strCommandProfileName = g_CmdManager->ProfileNameFromWnd( pRibbonBar->m_hWnd );
    ASSERT( strCommandProfileName != NULL && INT(_tcslen(strCommandProfileName)) > 0 );
CExtCmdItem * pCmdItem = g_CmdManager->CmdGetPtr( strCommandProfileName, nCommandID );
    ASSERT( pCmdItem != NULL );
    pCmdItem->m_strTipTool = _T("Tooltip text to be displayed in the popup tip window");

This work well thanks

CExtCmdItem * CMyRibbonBar::RibbonCmdIDtoCmdItem( UINT command_id )
{
    CExtCmdItem * pCmdItem = g_CmdManager->CmdGetPtr( g_CmdManager->ProfileNameFromWnd( m_hWnd ), command_id ) ;
    return( pCmdItem ) ;
}


void CMyRibbonBar::SetToolTips()
{
    INT nIndex, nCount = GetButtonsCount();
    for( nIndex = 0; nIndex < nCount; nIndex ++ ) {
        CExtBarButton * pTBB = GetButton( nIndex );
        ASSERT_VALID( pTBB );

        if ( pTBB->IsSeparator() )
            continue;

    UINT command_id = pTBB->GetCmdID( false ) ;
    CExtCmdItem * pCI = RibbonCmdIDtoCmdItem( command_id) ;
    if ( pCI != NULL )
        pCI->m_sTipTool.LoadString(command_id) ;

    } // for( nIndex = 0; nIndex < nCount; nIndex ++ )
}

CExtPopupMenuWnd::_OnMouseClick

Found a place to get the screen coords of the menu item
Changed your source only a little.

Dear Andrew,

Changing Prof-UIS code will bring inconvenience with each new Prof-UIS release. I think it should not be a problem to discuss any Prof-UIS modifications and put them into the library as you did or implement them in your classes which should be derived from Prof-UIS classes in scope of your project(s).

I can’t tell from the documentation, not that there is any, on how I can use CExtRibbonNodeDialogLauncher. I add it to a group on my ribbonbar and get a small arrow at the bottom of the group that I can click, but that is as far as I can get.
Thanks

The file menu has a set of menu entries to the left for file open, new etc.

When one of these menu entries is clicked, how can I get the screen coords of the clicked menu entry OnMouseClick

Dear Andrew,

The ribbon file menu is the UI item provided by the ribbon file button which is a kind of the ribbon gallery button. The ribbon gallery button displays the ribbon gallery popup menu which contains gallery control and/or a set of menu items. Simple ribbon gallery buttons are displaying ribbon gallery popup menu with the gallery control at the top and a set of menu items at the bottom. The ribbon file button is displaying the ribbon file popup menu with the gallery control at the right (typically displays recently used documents/files) and a set of menu items at the left (typically a set of classic file/print commands). Currently there are no virtual methods in the CExtRibbonPage/CExtRibbonBar classes for catching the mouse click position on the gallery control. The gallery control was designed to display a set of selectable checked/unchecked items wich are typically not similar to toolbar command buttons/menu command items. Could you explain why you need the mouse click location on the gallery control and how are you going to use it?

I am associating a dialog with file save as, file open, file new. Currently, I display these in the center of the app. However, to remain consistant with the RibbonBar I implemented, I would like the dialog just to the right of the menu entry.

On the top buttons, I use in the OnCommand handler GetButtonRect(CommandToIndex( command_id ), lpRect ) ;
Map lprect to coords relative to the ribbon bar for screen coords. Use lprect and SetWindowPos on the dialog to drop it just below the Ribbon button to function as a multi data input menu instead of single data input menus. It works fine.

Similarly, I want to drop a dialog just to the right of the file menu entry. It help maintain user context.

If you could tell me where the function and source file is where the click occurs, I will figure a way around it or change the source code myself.


    

Dear Support.

I have a docking bar, which can be floating.

The user can open the bar and close it (normal behaviour)
Each time the bar is re-opened, it can show a different dialog, so i destroy the previous dialog in the bar, and create a new child dialog whose parent is the bar.
Each time the bar is re-opened, i reset the size of the bar using the normal code:

pBar->SetInitDesiredSizeFloating(CSize(300,300));
pBar->SetInitDesiredPosFloating(CPoint(100,100));
pBar->FloatControlBar(CPoint(100,100));
CFrameWnd* pFrame = pBar->GetParentFrame();
pFrame->RecalcLayout();
pFrame->SendMessage(WM_NCPAINT);

This does not work.
The bar is moved to (100,100), but does not resize itself to (300,300)

Please fix.

Thanks,
Ron.

Dear Ron,

You can try to repeat the problem in the ChangeFloatingSize test project and send it to technical support.

Dear Support,

I Sent you yesterday a project repeating the bug.

Could you tell me please how to remove caption from CControlBar?

I want to perform a custom action when a hyperlink property is clicked. I don’t want a web browser to open or anything, just opening a messagebox or similar. I’ve tried overriding all four OnHyperLinkOpenXXX functions, but none of them are ever called. What is the proper way to do this?

Thanks a lot for your help, the OnHyperLinkOpen function is called correctly now. However, I’m having difficulty adding member variables. After some testing I added an integer member to the "Ex" class constructed to "5555", but immediately after creation assigned to "7777". I set a breakpoint in OnHyperLinkOpen and the integer has returned to its constructed value of 5555. Is the class being reconstructed by MFC/Prof-UIS, and if so, is this by design?

Each CExtPropertyValue instance keeps two CExtGridCell objects: the active one and the initial one. The later is used for the reset operation. These objects never appear inside tree grids in the property grid control and are stored inside CExtPropertyValue only. Each tree grid window in the property grid control contains cloned copies of active grid cells in property values. That is why you have different cell copies. When the editing is complete in some tree grid window, the property grid control assigns a new cell value to the active cell in the property value and to the all cells of this property value in other tree grid windows. If you have a combined property store, each property value is a reference to several simple property values and the result of editing is assigned to all the referenced property values. So, if you use a custome grid cell class which contains its specific data members, then it is important to override the CExtGridCell::Assign() virtual method like as follows:

void CYourCell::Assign( const CExtGridCell & other )
{
    ASSERT_VALID( this );
    CBaseCell::Assign( other );
CYourCell * pCell =
        DYNAMIC_DOWNCAST(
            CYourCell,
            ( const_cast < CExtGridCell * > ( &other ) )
            );
    if( pCell != NULL )
    {
        // assign all the specific data members
    } // if( pCell != NULL )
    else
    {
        // clear all the specific data members
    } // else if( pCell != NULL )
}

I don’t know the real solution, but can point out some aspects of PropertyGrid that could help you find the problem: For every property you see appearing in the grid there are 3 CExtGridCell objects you have to keep in mind:
- one of them is inside the grid, that is the one users can see.
- there are 2 other cells, these are the ones you get when you call PropertyItem’s ValueActiveGet() and ValueDefaultGet().

When the grid first appears it initializes its cell from the default cell of the corresponding propertyitem. When the user changes something in the cell the grid calls Assign, which is used to copy the new value to the propertyitem’s active cell. When user right-clicks cell and chooses Reset from the context menu, the grid copies content of propertyitem’s default cell into the cell appearing in the grid.

I think it is impossible that some Prof-UIS code changes the value of your member variable. I’m guessing you have some code that changes the member variable to 7777, but you are not aware that and how this code is called. And you should keep in mind that OnHyperLinkOpen is called for the cell appearing in the grid, not for the propertyitem’s active cell. You should tell some more about your classes to find out the real problem. Or try reproducing the problem in a sample application or in any of Prof-UIS samples.

Hi,

Here’s the class I am using to override:

// Overridden OnHyperlinkOpen
class CExtGridCellHyperLinkEx : public CExtGridCellHyperLink {
public:
    virtual bool OnHyperLinkOpen(
        __EXT_MFC_SAFE_LPCTSTR strURL,
        e_OpenMode_t eOM = __EOM_OPEN,
        bool bAllowErrorAlert = false
        ) const {
            MessageBox(NULL, "Link click", NULL, NULL);
            return false;
    }
};



I simply replace the standard class with this "Ex" class in the creation, like so:

CExtGridCellHyperLinkEx* pLink = STATIC_DOWNCAST(CExtGridCellHyperLinkEx,
                         pItem->ValueDefaultGetByRTC(RUNTIME_CLASS(CExtGridCellHyperLinkEx)));

The grid cell contains a hyperlink control, but when clicked, it still opens a browser and tries to visit a website. What am I missing?

In SimpleGrids sample you can see that overriding a CExtGridCell-derived class is a little more tricky than overriding a usual class. Here are the code-snippets you have to put in your project (I checked it in PageGrid class of ProfUIS_Controls sample).
In .h:

class CExtGridCellHyperLinkEx : public CExtGridCellHyperLink 
{
	DECLARE_DYNCREATE(CExtGridCellHyperLinkEx);
	IMPLEMENT_ExtGridCell_Clone( CExtGridCellHyperLinkEx, CExtGridCellHyperLink );
	CExtGridCellHyperLinkEx(
		CExtGridDataProvider * pDP = NULL
		);
public:
	virtual bool OnHyperLinkOpen(
		__EXT_MFC_SAFE_LPCTSTR strURL,
		e_OpenMode_t eOM = __EOM_OPEN,
		bool bAllowErrorAlert = false
		) const 
	{
		TRACE0("My HyperLinkOpen called");
		return true;
	}
};

In .cpp:

...
#include ".\pagegrid.h"
 
// moved to top (i.e. before DEBUG_NEW) to avoid
// conflict with MFC’s operator new
IMPLEMENT_DYNCREATE(CExtGridCellHyperLinkEx, CExtGridCellHyperLink);
 
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
...

And then I used STATIC_DOWNCAST when initializing cells.

With this code you can see the message "My HyperLinkOpen called" in the Output window of the VS when the cell is clicked. In the overriden OnHyperLinkOpen make sure you return true;, because this method is called in CExtGridCellHyperLink::OnClick like this: VERIFY( OnHyperLinkOpen( LPCTSTR(strURL) ) ); So debug version of your project would throw an assert if you returned false.

Although I tried using the cell inside a CExtGridWnd, not a PropertyGrid, the usage must be the same.

Sorry, I forgot to paste constructor for the class (this goes in .cpp):

CExtGridCellHyperLinkEx::CExtGridCellHyperLinkEx(
	CExtGridDataProvider * pDP // = NULL
	)
	: CExtGridCellHyperLink( pDP )
{
}

I’m using a CExtGridCellCurrency to display percentages. I set it up like so:

pCurrency->SetNumDigits(6);
pCurrency->SetCurrencySymbol("%");
pCurrency->SetPositiveOrder(1);
pCurrency->SetNegativeOrder(5);

This means a value of 50.5 shows up as "50.500000%", and 100 shows up "100.000000%".
Is there any way to remove the trailing zeroes? I would like 50.5 to show up as "50.5%", and 100 to show up as "100%".

Dear Support,

How can i add icons to my popup menus?
The commands in the popup menus do not appear in the main-frame menu.

Thanks,
Ron.

You should create an additional toolbar resource with the commands that you are going to use in the menu. Then update the command manager with this toolbar using g_CmdManager->UpdateFromToolBar() method. This should be enough to make the icons appear in the command manager.

How to remove the close button from the CExtControlBar caption?

How to save UI theme state so the last used theme is restored after app restart?

Dear Support,

We have several legacy controls that are CListCtrl derived.
Is there any simple whay to make these controls conform with the themes of Prof-UIS?
If not, how do you suggest to handle this problem? at least replacing the title bar of report-style CListCtrl.

Hi,

I am using g_PaintManager->m_FontBold to get the deafult bold font. when using CExtPaintManagerOffice2007_R3_Obsidian, i assumed it will return me a white bold font, but i get a black bold font.

How can i get a while bold font?

Thanks,
Ron.

The g_PaintManager->m_FontBold is just a font. When drawing text you can specify a color using the CDC::SetTextColor() method.

There is a CExtPaintManager::QueryObjectTextColor() method that can be useful if you want the color compatible with the current theme.

I have added this to my code:

    m_clrText =
        PmBridge_GetPM()->QueryObjectTextColor(
        dcFake,
        true,
        false,
        false,
        false,
        (CObject*)this
        );

And i get -1.

I stepped in, and this is where i got:


COLORREF CExtPaintManager::QueryObjectTextColor(
    CDC & dc,
    bool bEnabled,
    bool bFocused,
    bool bHovered,
    bool bPressed,
    CObject * pHelperSrc,
    LPARAM lParam // = 0L
    )
{
    ASSERT_VALID( this );
    dc;
    bEnabled;
    bFocused;
    bHovered;
    bPressed;
    pHelperSrc;
    lParam;
    return COLORREF(-1L);
}


What is the problem? What am i missing?

Thanks,
Ron.

Actually the QueryObjectTextColor() method is used only in the paint manager that produces the Obsidian (Black) theme so you need to analyze the returned color. If it is COLORREF(-1L), you should specify the color yourself:

m_clrText =
    PmBridge_GetPM()->QueryObjectTextColor(
        dcFake,
        bEnabled,
        false,
        false,
        false,
        (CObject*)this
        );
if( m_clrText == COLORREF(-1L) )
    m_clrText =
        bEnabled 
            ? PmBridge_GetPM()->GetColor( COLOR_WINDOWTEXT )
            : PmBridge_GetPM()->GetColor( COLOR_3DSHADOW );

We are sorry for being inaccurate in the previous reply.

Hi,

I have a CWnd* Derived control inside a CExtResizableDialog dialog.
I haev added this code to the drawing of the control as suggested by you before:


bool bTransparent = false;

if(! bTransparent && PmBridge_GetPM()->GetCb2DbTransparentMode(this))
{
     CExtPaintManager::stat_ExcludeChildAreas(
         *pDC,
         GetSafeHwnd(),
         CExtPaintManager::stat_DefExcludeChildAreaCallback
         );

     if(PmBridge_GetPM()->PaintDockerBkgnd(true, *pDC, this))
     {
         bTransparent = true;
     }
}

if (! bTransparent)
{
     pDC->FillSolidRect(
         &rc,
         PmBridge_GetPM()->GetColor(CExtPaintManager::CLR_3DFACE_OUT, this));

}


The problem is that this control appears 4 times in the dialog (and there are some other standard controls as well...), and what happens is that all controls in the dialog are not displayed, only the last control is displayed.

I think that what happens is that this piece of code draws the whole dialog with the background color, and that’s why none of the controls is shown.

I can see that when i resize the dialog, the controls appear for a short time (flicker), and dissapear again.

How can i make sure that the control repaints only its region and not the whole dialog?

Thanks.

Please try the following code and let us know if the problem persists:

CRect rcClient;
GetClientRect( &rcClient );
if( rcClient.IsRectEmpty() )
    return;

CPaintDC dcPaint( this );

CExtMemoryDC dc(
    &dcPaint,
    &rcClient
    );

CRgn rgnClient;
if( rgnClient.CreateRectRgnIndirect( &rcClient ) )
    dc.SelectClipRgn( &rgnClient );

// ...
// ...
// PLACE YOUR PAINTING CODE HERE 
// ...
// ...

if( rgnClient.GetSafeHandle() != NULL )
    dc.SelectClipRgn( &rgnClient );

Thanks,
Problem solved.

Just for understanding - you need to repaint the complete background of the dialog for each control? Isn’t there a performance penalty?

If you have a large number of controls (e.g. 50), you will certainly face some performance issues. But there is no other way to draw a solid gradient background. On the other hand, lots of controls on a dialog cannot be considered as a user-friendly design. For example, you could divide controls into lesser groups and smaller dialogs, tabs and etc. Another good solution could be a property grid control.

Does the large number apply to ALL controls, including CExtLabel, CExtEdit etc.?
If I don’t use theme with gradient background, does it still carry the same pennalty?

I have a program with the following glitch. In the glitch I have a View for an SDI, and a controlbar with a dialog.

When a controlbar is going into hiding (it is pinned and the mouse is moved away), if I move my mouse back over the control bar, the dialog components, buttons, labels, et cetera, become visible but the dialog does not. It is as if, the dialog itself is being clipped by the view but the dialog components don’t know that. The biggest problem with that is that the controlbar is not hidden, the borders are now invisible so the user cannot quickly see what to do to make it go away, and there are orphaned buttons floating over the view.

Can you help me by giving me an idea of where to troubleshoot this problem? My impression is that I am overlooking a relationship between your controlbar and the client region of the view.

Thanks,
Seth

An additional symptom is that when a controlbar is going to hide it disappears, and then as it is sliding away it reappears so it looks like a stutter.
