<!--StartFragment --> Hi,
  I’m wondering if it is possible to add French Canadian resources? I know that I can do it myself because I got the full source code. But, I’ll have to do it each time I install a new version. By now, I can switch all my application resources to French France but I’ll wait on your answer before taking any actions.

I am creating an application with an Outlook 2003 UI based on your PageNavigator sample. On the left pane (inside the Outlook nagivator control), I have a class derived from CExtResizableDialog. This contains a CTreeCtrl  (just like your sample).

The problem is that when the CTreeCtrl has focus, none of the keyboard shortcuts for the main menu work. For example, if I press Alt-F, the menu won’t open. If I set focus to any other view, the shortcuts work fine. Even your sample seems to be working fine, so I must be missing some simple message handler. Can you help?

I don’t know if it matters, but in my CMainFrame, I am handling PreTranslateMessage as follows:

BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
 if (m_wndMenuBar.TranslateMainFrameMessage(pMsg))
  return TRUE;

 return CFrameWnd::PreTranslateMessage(pMsg);
}

Thanks,

Hi Technical Support,

My application is MDI and uses Customization and Tab window for the management of the views within the frame window. I want the window to be closed when the user presses certain function keys. I tried sending WM_CLOSE maeesge to the view from the CMainFRame.cpp function. When WM_CLOSE is sent to the view, it calles the function OnDestroy() of the view but it does not get removed completly from the TAN window. Please note that the window will be removed completly when I click the close (x) button of the window.

AM I missing something here ? I am not being able to destroy the view from MDI Tab Frame window. Appreciate your help.

Saroj

Dear Saroj,

Both of the following invocations should close the window:

pWnd->DestroyWindow();

pWnd->SendMessage( WM_CLOSE );

pWnd->SendMessage( WM_SYSCOMMAND, SC_CLOSE );

Sent you my project and waiting for your response.

Thanks, Saroj

Yes, we received your project but we start analyzing it, could you check the following. You should not send the WM_CLOSE message to the view. WM_CLOSE should be sent to the child frame window that contains the view.

Hi, I am working on another application where depending upon the combobox selection in a property value, a different set of properties should appear below. For example, the initial view may look like this:

+ Donut properties
  Type of donut: (combobox)

+ Donut properties
  Type of donut: Glazed
    Amount of glaze: (combobox)

+ Donut properties
  Type of donut: Sprinkles
    Number of sprinkles: (edit box)

+ Donut properties
  Type of donut: Sprinkles
  + Sprinkle properties
    Number of sprinkles: (edit box)

Hi, I’m trying to get my different CExtPropertyStore objects combined so that I can modify their common properties. However, when I call combine and synchronize, all of the properties appear for each store

For example, instead of getting something like:

+ Store properties
   Color
   Height

+ Store1
   Color
   Height
+ Store2
   Color
   Height
+ Store 3
   Color
   Height

CExtPropertyValue* pValue = new CExtPropertyValue( label.c_str());
CExtGridCellComboBox* pData = STATIC_DOWNCAST( CExtGridCellComboBox, pValue->ValueActiveGetByRTC( RUNTIME_CLASS(CExtGridCellComboBox)));
pValue->ValueActiveSet( pData);

Ok, we figured it out. In order for Combine to do what we think it should do, the categories obviously need to have the same name. Whoops!

Is there a simple way to test whether horizontal/vertical scrollbars are visible in a CExtGridWnd? After changing the grid content I need to modify the column widths when the vertical scrollbar is displayed in order to prevent a horizontal scrollbar from also appearing.

Thanks,

David.

Hi ,

i would like to add CExtGridWnd control into a  CExtResizableDialog, but the sample code explains about how to add   control to the CExtTabPageContainerFlatWnd.

I don’t want tab page container, i would like to directly put the control on the CExtResizableDialog itself.

hope that you would send the sample code

Hi,

Thanks for the response. I sorted out the issue, i made a mistake by inserting the return statement inside the if condition " if( nRepCnt == 2 ) ". Once i took the return statement outside the loop it works.

 // if double click   
  //return   CExtGridWnd::OnGbwAnalyzeCellMouseClickEvent(nChar, nRepCnt, nFlags, point );
 }

  return   CExtGridWnd::OnGbwAnalyzeCellMouseClickEvent(nChar, nRepCnt, nFlags, point );
}

It is suppose to take the default action except double click.

Also i made a correction by adding

 if ( (pCell != NULL)  && (!pCell->IsKindOf(RUNTIME_CLASS(CExtGridCellHeader)))) to avoid the procedure gets fired when the user double clicks on the header itself.

thanks for the mail.

sundar

Hi,

Thanks for the Code, Now it works fine. But it has disabled the nice feature of SORTING . Now it doesn’t sort when you click on the headers. Hope that you would resolve this issue.

thanks & regards

sundar

To enable the sorting feature for columns in your grid, just apply the __EGWS_BSE_SORT_COLUMNS style:

m_wndGrid. BseModifyStyle( __EGWS_BSE_SORT_COLUMNS, 0 );

We have sent you a sample project by e-mail. This very simple project demonstrates how to use the grid control in the dialog.

Hello,

I’m also interested for this sample.

Could you send it to me by mail ?

Regards,

Simon

I just posted this same question, before discovering this post.  Please email me the sample too...

thanks,

Eli

We sent you this sample by e-mail.

We sent you this application by e-mail as you requested.

Hi,

Thanks for the Code, By the way is there any way to have a double click method on the grid ( like listctrl control) ? Thanks for the reply.

expecting your reply

sundar

Dear support team,

the downloaded zip achive of version 2.42 seems corrupt.

Can I have the background of a palette menu like the background of a toolbar (with gradient) to have a consistent appearance. Maybe it is already done in version 2.42 but was not in version 2.41 by default.

Best regards,

Axel

I am building a UI similar to Outlook 2003 by following your sample. The navigation control is working great!

Next, I want to create the middle portion of Outlook UI, where the messages or items are displayed. At the top of that portion, a title has to be displayed (e.g. "Inbox", "Notes", "Calendar" etc).

How do I use Prof UIS to display such a gradient caption on top of a list view control? You are already using it at the top of the Outlook Navigation control, so I’m wondering if the gradient text control can be used independantly.

Thanks.

If you are using the PageNavigator application for your new project AS IS, then you can simply draw the caption at the top of the CChildView area. Here is the updated source code for the CChildView::OnPaint() method:

void CChildView::OnPaint() 
{
CRect rcClient;
    GetClientRect( &rcClient );
CPaintDC dcPaint( this );
CExtMemoryDC dc( &dcPaint, &rcClient );
    dc.FillSolidRect(
        rcClient, 
        g_PaintManager->GetColor(
            COLOR_WINDOW,
            (CObject*)this
            )
        );
    g_PaintManager->PaintResizableBarChildNcAreaRect(
        dc,
        rcClient,
        this
        );
CRect rcCaption = rcClient;
    rcCaption.bottom = rcCaption.top + 25;
CExtSafeString sCaption = _T("PageNavigator");
    g_PaintManager->PaintPageNavigatorItemCaption(
        dc,
        rcCaption,
        sCaption
        );
    g_PaintManager->PaintResizableBarChildNcAreaRect(
        dc,
        rcCaption,
        this
        );
}

Thank you, that worked great! One more question:

In this line:
rcCaption.bottom = rcCaption.top + 25; 

The value 25 is hard coded. Is it also hard coded in the ProfUIS library? If not, is there a way to dynamically obtain the title bar’s height instead of hard coding?

Thanks!

I have two problems.

1. I have certain control bars where I don’t want the right click menu that lists all the control bars in my application to appear.

2. When I create a dynamic docking window.  It shows up in the right click menu, but is disabled.  I do not want it to appear in the menu at all.

We assume you are using dynamic resizable control bars (the CExtDynamicControlBar class) which are managed by the dynamic bar site (the CExtDynamicBarSite class). To customize context menus of particular bars, you need to use your own CExtDynamicControlBar-derived class. Your dynamic control bar should override the CExtDynamicControlBar::OnInitDbsMenu() and return false. This will suppress the menus as you requested. To make the dynamic bar site create the control bars of your type, override its CExtDynamicBarSite::OnDbsCreateNewBarInstance() method which should simply return newly created bars of your class.

I’m actually using CExtControlBar.

I changed my derived class to one of CExtDynamicControlBar and did what you had said.  If you return false in OnInitDbsMenu the CExtDynamicControlBar Class ASSERTS.

I’m not trying to suppress that menu.  Now I have a CExtDynamicControlBar derived class that has a dialog on it.  The dialog has a series of controls.  When I right click on any of the ctrls or on the control bar itself I get a menu that lists all the menu bars, control bars, and so on.  I do not want this menu or would like to modify the behavior of this menu.  This is same menu that occurs when you right click up in the frame area between menu and my view area.

Hello,

I am having a problem with the CExtGridWnd::RowInsert() function in that it doesn’t appear to be inserting a new row when I tell it to!!!

Let me explain the scenario. My application first starts up with a splitter window containing a grid on the left and other program controls on the right. This grid is working absolutely fine. At a certain point in the program I then attempt to open up a new CMdiChildWnd also with a splitter window and containing another grid on the left and other program controls on the right. For some strange reason the RowInsert function is failing on this second window!!! I have confirmed this by call RowCountGet() which returns -1. The grid is definitely being initialised correctly as all the column headers are being displayed - I just can’t seem to insert any rows!!!

Can you offer any advice as to why this may not be working as expected???

Regards,

David.

The CExtGridWnd::RowCountGet() method returns a greater or equal to zero number of rows for the grid window which completely manages a two dimensional array of CExtGridCell objects in the application memory. That is the default behavior of the CExtGridWnd class. The CExtGridWnd::RowCountGet() method returns a negative value in the two cases that follow. First, the vertical scrolling strategy is set to virtual (__ESIW_ST_VIRTUAL). The virtual scrolling permits the thumb button to be only at the home, middle, or end position. This scrolling mode used for working with data of an unknown number of rows and/or columns. The AdoRecorsetView sample application allows you to browse database records in the virtual mode. The virtual scrolling mode requires a custom data provider component to be created and attached to the grid window. If you do not use the virtual scrolling and custom data providers in your application, then we may guess your code simply initializes the grid window incorrectly by specifying some invalid style flags. You may send us your project so that we can clarify the problem.

I am populating the grid in the OnInitialUpdate() on both child windows. The code is very similar in structure and so there is no logical reason as to why it should work fine on the first and not on the second!

Please give me a more logical answer with which I can actually make progress...

We just explained what may mean a negative value returned from the CExtGridWnd::RowInsert(). To provide you with a problem solution, we need more details about your application. Debugging your project is the most convenient way for us. At least, we need to take a look at the source code of the OnInitDialog() method which initializes the grid window that causes the problem.

Unfortunately I cannot provide the entire code for the application but I have included below the relevant code snippets relating to the grid definition and initialisation.

Hope this helps,

David.

Here is the code snippet from your message:

m_Grid.SiwModifyStyle(
   __ESIS_STH_PIXEL 
   //|__ESIS_STV_ITEM
   //|__EGBS_SFM_FULL_ROWS
   //|__EGBS_NO_HIDE_SELECTION
   |__EGBS_GRIDLINES
   ,__ESIW_ST_VIRTUAL, false
   );

I have changed the code snippet above to:

m_Grid.SiwModifyStyle(

__ESIS_STH_PIXEL

|__ESIS_STV_ITEM

//|__EGBS_SFM_FULL_ROWS

//|__EGBS_NO_HIDE_SELECTION

|__EGBS_GRIDLINES

,__ESIS_STV_VIRTUAL,false

);

as suggested but still no success! The row count is still being returned as -1 and no rows are added! Interestingly if I move all the initialisation code to the OnCreate function the row count increases as new rows are added but the grid is not displayed - not even the header cells!

Why does it work fine on one child window and not another???

Regards,

David.

At this point we see two ways to solve this problem:

A) You will send us source code of the class that creates the grid control and initializes it unsuccessfully.

B) You will contact us by e-mail or phone call so that we can arrange a web conference which will allow us to fix the problem without sending us any source code.

After closer inspection I’ve tracked down and corrected the problem :)

For some reason on the second child window I had used:

__ESIW_ST_VIRTUAL

instead of __ESIS_STV_VIRTUAL

I corrected this and it now works as expected!

David.

Please advise as to how we can setup a web conference

We sent you instructions on the issue of remote debugging by e-mail.

A quick question,

     How do I go about displaying multiline CExtGridCellStringDM grid cells? And will the rows automatically stretch to the cell height?

   Regards,

         Eddie

Hi,

   I changed the CMainApp::InitInstance() in the prof-uis controls sample application to the following:

if( m_pszProfileName != NULL )

free( (void*)m_pszProfileName );

#ifdef _DEBUG

#endif

pdlg=new CMainDlg();

int nResponse = pdlg->DoModal();

if (nResponse == IDOK)

// TODO: Place code here to handle when the dialog is

// dismissed with OK

else if (nResponse == IDCANCEL)

// TODO: Place code here to handle when the dialog is

// dismissed with Cancel

delete pdlg;

#ifdef _DEBUG

if( diffMemState.Difference( oldMemState, newMemState ) )

#endif

// Since the dialog has been closed, return FALSE so that we exit the

// application, rather than start the application’s message pump.

return FALSE;

and ran it in debug mode, could you tell me how I can clean up properly as I am getting:

There are no memory leaks in the ProfUIS_Controls sample application. The un-allocated block in the memory dump listed in your message will be de-allocated later during the application shutdown. This block is used by the internal API of the CExtHookSink class which is used by the CExtMenuControlBar class.

I too am having memory leaks.
Many of them.
Thye look like the following:

Data: <{ > 7B C6 12 00
C:\Program Files\FOSS Software Inc\Prof-UIS\Src\ExtHook.cpp(579) : {41022} normal block at 0x01EDAC58, 29 bytes long.
Data: < 3 > CC D4 82 33 01 C0 AC ED 01 01 00 00 00 01 00 00
afxtempl.h(330) : {41021} normal block at 0x01EDAC10, 4 bytes long.

I thought I would run it by you before I start debuging this.

This typically means nothing is deallocated at all and, if you set a break point in the destructor of the main frame/dialog window, it will never be invoked in the debug mode. Please try debugging the deinitialization sequence and find out when and why the application terminates. This can be either an unhandled exception or an invocation of the ExitProcess() API.

All destructors are invoked.
First of all, these memory leaks are comming from the CExtTabPageContainerWnd which derives from CExtHookSink.
Here is the situation.
I have a dialog containing a tab control.
This tab control is derived from CExtTabPageContainerWnd.
Using the PageInsert method, I insert my tab dialogs.
For debuging purpouses I’ve remove all tabs except for one.
So I now have a dialog with a tab control contianing one tab.
Inside this tab there is a dialog containing 3 edit contorls.
These edit controls are derived from CExtEdit.
All dialog were created in the resource manager.
The tab control is subclassed using DDX_Control(pDX, TABID, m_tabCtrl);
The edit boxes are subclassed using the MFC SubclassWindow function.
Now if I open this dialog and close it, and close my application, I get three memory leaks in my dump.
It seems to be one memory leak for each edit control (destructor is called in the edit control).

On line 139 in CExtHook there is the following code:

        if( bDelete )
            delete this;

If I put a break point on the line "delete this", I miss 3 hit.
Any help would be appreciated.

We have similar tab pages in the ProfUIS_Controls sample and we do not see any leak there. So, we can guess this depends on some conditions specific to your project only. Could you create a lightweight version of your project which generates leaks and send it to us?

Hi,

is it possible to change the font of toolbar button?

Hi tech Support,

I want to disable the docking markers from my application. How would I do that ? All my control bars are floating and should expand between two monitors. I do not want to show the docking markers when the user moves the control bars around.

Appreciate your help.

Saroj

You can use the Visual Studio 2005 UI theme without docking markers. Just invoke the following code:

CExtControlBar::g_eResizablePanelDockingType =
     CExtControlBar::__RESIZABLE_DOCKING_TYPE_STUDIO_2003;

I’ve got a toolbar button that has an attached popup menu. It has a mysterious delay of 1-2 seconds between clicking on a menu item and hitting a breakpoint in the menu item handler. I tracked it down to CExtBarButton::OnTrackPopup(). It looks like the delay is within that routine, between the call to pPopup->TrackPopupMenu() and getting the clicked command id. After that, things are fast.

Any ideas on what to look for or what I can try?

Thanks

I have a SDI app.
On the toolbar I got a button with id ID_PLAY_NEXT.

I also have a ControlBar with a Dialog in it.
In the dialog I try to catch the command ID_PLAY_NEXT with ON_COMMAND(ID_PLAY_NEXT, OnPlayNext).
It do not work. However, if I do exactly the same in CMainFrame it do work. How can I catch it in the child dialog?

Another question. How do I use a hottrack bitmap for the toolbar?

I got a problem with a toolbar bitmap.
It’s displayed incorrectly.
Have you any idea why?

We recommend you use device independent bitmaps (DIB) in toolbar resources. The DIBs are produced by MSPaint and Visual Studio resource editor. Many advanced graphics editors like Adobe Photo Shop can produce bitmaps in non-DIB formats and these bitmaps may be loaded by Prof-UIS incorrectly. Please create a new bitmap in MSPaint editor, paste the existing bitmap into it and, finally, override existing toolbar’s BMP file.

It works with 16 color images, but not 256.

Hi, I’m following the latest example for the property grid control. I now have the in place combobox working to the point that it displays the strings that I’d like displayed. Now I have two questions:

1. How can I make this combobox a droplist (i.e. not editable) instead? I assume it’s a window style, so perhaps I need to subclass CExtGridCellComboBox (and thus also use the IMPLEMENT_ExtGridCell_Clone macro) and then set the window style upon creation. Can you please confirm this?

2. Currently, I have four strings in the in place combobox. For starters, I just want to display a MessageBox anytime a user selects a string. I’ve put the code in Apply(), just like the example. However, this method gets called as soon as I click on the dropdown arrow, which seems a little weird to me since I haven’t actually selected anything yet. Also, as long as I select an item from the droplist, everything is basically ok (except that the messagebox is obscured by the droplist). However, if I type in the edit box and then set the focus elsewhere, my application crashes.

Thanks again,
Dave

I have another question regarding the property grid control. I have something that looks like this:

MyStore <-- comboboxbar

+ Field 1 <-- category
  Source    | Database |v|| <-- property value, combobox 

For database case:
+ Field 1
  Source    | Database |v||
    Query    | <enter sql query here> |

For file case:
+ Field 1
  Source    | File          |v||
    Filename    | <enter filename nere> |

+ Field 1
  + Attributes
    Source    | Database |v||

+ Field 1
  Source    | Database |v||
  + Attributes

What you need is automatically supported by the property grid control. The CExtPropertyGridComboBoxBar class is part of the CExtPropertyGridCtrl component. The combo box bar keeps a collection of property stores and displays content of the selected property store in the property grid control. This bar in the PropertyGrid sample application contains one property store for each star button on the main dialog window and two combined property stores. The combined property store is a result of the operation called property tree combining. This operation is performed by the CExtPropertyItem::Combine() method and allows you to see properties of several stores in a new combined property store. The similar property value with different CExtGridCell values are displayed as empty/undefined values in the property grid control. Editing an undefined property value changes property values in all the property stores used in the property tree combining operation. The combined property store is a separate CExtPropertyStore instance. To create a combined property store, call its Combine() method.

The CMainDlg::_CombineMixedStoreAll() and CMainDlg::_CombineMixedStoreSelection() methods in the PropertyGrid sample application demonstrates how to combine property stores. The following code snippet in the CMainDlg::OnInitDialog() method shows how to get a pointer to the combo box bar and initialize its content:

CExtPropertyGridComboBoxBar * pCombo =
    STATIC_DOWNCAST(
        CExtPropertyGridComboBoxBar,
            m_PGC.GetChildByRTC(
            RUNTIME_CLASS(CExtPropertyGridComboBoxBar)
            )
        );
 ASSERT_VALID( pCombo );
 pCombo->PropertyStoreInsert( &m_PropertyStoreCompoundSelection );
 pCombo->PropertyStoreInsert( &m_PropertyStoreAll );
 pCombo->PropertyStoreInsert( m_Btn1.GetPropertyStore() );
 pCombo->PropertyStoreInsert( m_Btn2.GetPropertyStore() );
 pCombo->PropertyStoreInsert( m_Btn3.GetPropertyStore() );
 pCombo->PropertyStoreInsert( m_Btn4.GetPropertyStore() );

To make any CExtGridCell object (including CExtGridCellComboBox) non-editable, just apply the __EGCS_READ_ONLY cell style to make the in-place editor control read-only. You can apply the __EGCS_NO_INPLACE_CONTROL cell style to disable activation of the in-place editor control at all. You can change the style of the grid cell object by using the ModifyStyle() method of the grid cell objects used in property values.

To catch the selection change event, create a CExtGridCellComboBox-derived class and override the CExtGridCell::OnPopupListBoxSelEndOK() virtual method which should return the value from parent method and perform your custom actions. You can invoke the wndListBox.GetCurSel() code to get the finally selected item’s index in the pop-up list box.

Hi, I think I need to clarify what I was asking for earlier. I’m not interested in making an inplace combobox readonly, actually. I want to just make sure that the user can only select items that I’ve explicitly added to the list (i.e. dropLIST). The default mode is dropdown, which allows a user to type text into the inplace combobox. Is it possible to get droplist functionality? I couldn’t find any style modifiers for this.

You can apply the __EGCS_NO_INPLACE_CONTROL style to any grid cell object by using its CExtGridCell::ModifyStyle() method. Such a grid cell, which shows pop-up list box by clicking its drop-down button, will behave as drop-down-list combo box control. You should apply the __EGCS_NO_INPLACE_CONTROL style to the cell objects used inside property values.

That seems to work okay, however, I’d like it to be more like standard droplist comboboxes, where clicking on the blank area itself (and not just the dropdown arrow) will cause the list to appear. Can this be added?

Hi Customer Support,

My application has two slider controls in the toobar. Both of these controls are placed in the window derived from CExtResizableDialog. My problem is that they are not visible when I first display the window. But when I resize the same window, both of the slider controls will appear in the right place. I tried calling various functions such as pSliderControl->Show(),  pSliderControl->RecalcSliderLayout() or m_wndToolBar.Invalidate() & m_wndToolBar.RedrawWindow(), but none of them help.

Can you help me with this problem ? The only thing that will show these controls is to resize the window by slightly changing it’s size. When another window (lets sat Windows Explorer) totally covers this wiondow and it reappears, the controls will not reappear. That means WM_PAINT is not helping.

Thanks for your help.

Saroj

Please make sure that you use the RepositionBars method. It should be called at the end of the OnInitDialog method:

BOOL CPageToolbars::OnInitDialog() 

{

    CPageBase::OnInitDialog();

    ...    

    ...

    ...

    CWnd::RepositionBars(0,0xFFFF,0);

    return TRUE;

}

void CPageToolbars::OnSize(UINT nType, int cx, int cy) 

{

    CPageBase::OnSize(nType, cx, cy);

    if( nType != SIZE_MINIMIZED )

        CWnd::RepositionBars(0,0xFFFF,0);

}

CWnd::RepositionBars(0,0xFFFF,0);

m_wndToolBar.SetWindowPos(

        NULL, 0, 0, 0, 0,

        SWP_NOSIZE|SWP_NOMOVE|SWP_NOZORDER|SWP_NOOWNERZORDER

        |SWP_NOCOPYBITS|SWP_NOACTIVATE

        |SWP_FRAMECHANGED

        );

Thanks for the prompt reply.

I double checked my code and looks like I had everything in my code you mentioned in the email except the code to send WM_SIZE message to the window. I try putting that code in, and I still do not see those two Slider controls when the application first starts. But it will appear as soon as I change the size of that window.

Any idea why ? I could send you my entire project if you would like to have a look.

Regards,

Saroj

Please also try to update you toolbar in this way:

    CRect rcWindow;

    m_wndToolBar.GetWindowRect( &rcWindow );

    m_wndToolBar.SetWindowPos(

        NULL, 0, 0, 

        rcWindow.Width(), rcWindow.Height(),

        SWP_NOMOVE|SWP_NOZORDER|SWP_NOOWNERZORDER

        |SWP_NOCOPYBITS|SWP_NOACTIVATE

        |SWP_FRAMECHANGED

        );

I even tried this latest code, it does not help. I still do not see those two slider controls in the toolbar. BUt when the window is re-sized, they appear.

Saroj

If you send us your project that would help us to quickly find out what’s wrong with this issue.

I sent you my project and hopefully it will help you find the problem.

We tested your project and found no problems. The slider is always visible when the control bar becomes visible. We sent you our recommendations and advice by e-mail.
