Dear Support,

When I change the font of a dialog from size 8 to 10, all controls are automatically change to the right size, but not the CExtTabPageContainerWnd control.

Please note that even if I add the following line in OnInitDialog

m_ctrlTab.SetFont(GetFont());

The font does not change.

Please fix, and if possible send me a patch for this problem ASAP.

Thanks,
Ron.

Dear Support,

I have a modeless dialog in my SDI application. Actually the MainFrame has a pointer member variable which is NULL first, but then I allocate it with new in a command handler. When user clicks X button on dialog, I destroy it. All seem to work fine. There’s just a little thing: If I fire the command through toolbar button, the button visually stayes hovered and goes back to normal state only if I hover over any button of same toolbar. There’s no UpdateCommandUI handler for my buggy button.

What am I doing wrong?

I reproduced the problem in a modified ThemeColorizer sample. If you need to check it, you can download it from here. I connected the handler to the Rectangle Selection button.

Thank you and have a nice weekend!

We are using a custom paintmanager derived from CExtPaintManagerStudio2005. It is almost the same as your CColorizedThemeOffice2003 in ThemeColorizer sample.
I get the warning "Cannot call WriteClass/WriteObject for ..." in the VS Output window. I traced it down, it gets called somewhere inside InstallPaintManager. I checked, same happens in your ThemeColorizer sample as well.
I’m guessing it is connected to your new PaintManagerStateSerialize feature. Am I right? How could I fix it?
It’s really no big mistake, users won’t notice anything, I just would like to clear it up.

Thank you.

hello, i want to deactivate one row in my Grid to runtime.
Is this possible?

Thank you for this great foru.

Dear Support,

When the tab control orientation is to the right side, and theme is one of the R1, R2 or R3 themes, the limiter line between the tabs is missing.
You can reproduce it by running the ProfUIS_Controls, and change the tab orientation to right.

Please note that in left orientation the lines are there...

Ron.

I am using a slider button similar to the one implemented in the AviFrames example. However, I am getting an uninitialized value if I click on the slider button and release it without moving it away from its original position.

The bad value first occurs in the following code:

virtual void OnClick( CPoint point, bool bDown )
{
   CExtBarSliderButton::OnClick(point,bDown);
   TRACE( "OnClick, Scroll Pos: %u\n", m_nScrollPos );	 
}

The value of m_nScrollPos is 3452816845 which is 0xCDCDCDCD. I believe this means the memory is uninitialized. This is weird since it is initialized to 0L in the constructor.

Any help would be greatly appreciated. Thanks!

Hmmm... I can’t reproduce it anymore. If it does appear again I’ll make a sample to send to you. Thanks!

I am overriding OnClick() because I only want an action to occur when the user releases the mouse button after dragging. ScrollPosSet() is called for many values when dragging, but I only want the final position of the slider, rather than updated values along the way.

We tried to reproduce this bug with our AviFrames sample but failed. Would you send us your project or a modified version of the AviFrames sample that reproduces the bug?

Do you have CFileDialog, AfxMessageBox consistant with PaintManager

Dear Support,

This class contains a lot of text changing function, but i could not find any function to change the font’s size?
How can this be done? Why isn’t there a function for doing this?

Regards,
Ron.

Can’t you use the SetFont function?

I can, but it will look like this:

    CFont* pFont = m_lblMessage.GetFont();
    LOGFONT logFont;
    pFont->GetLogFont(&logFont);
    logFont.lfHeight -=4;
    CFont* pNewFont = new CFont;
    pNewFont->CreateFontIndirect(&logFont);
    m_lblMessage.SetFont(pNewFont);


Instead of one line...

All i’m saying is that i think that such a nice class can have an option to allow simple font’s parameters changing.

I’m having trouble with my menu items when I use keyboard accelerators to invoke them. I believe the problem is because I handle the message in a child class of CFrameWnd which is a CExtResizeableDlg.

Everything works fine if I select the menu item with the mouse. And the keyboard accelerator works fine anytime I have previously selected a menu item from the application. But if I set focus to my CExtGrid control and try the accelerator, it never works. I assume this is a problem with PreTranslateMsg(), but I’m not sure how to fix it.

My window hierarchy is this:

CExtNCW < CFrameWnd >
    CExtTabPageContainerWnd
        CExtResizableDialog <<< handles menu item
        
Thanks,
Scott

            

The problem is caused by the message pre-translation implemented in the CDialog class. Everything should work if you override the CWnd::PreTranslateMessage() virtual method in your dialog class:

BOOL CYourDialogClass::PreTranslateMessage( MSG * pMSG )
{
    if(     WM_KEYFIRST <= pMSG->message && pMSG->message <= WM_KEYLAST
        &&  ( pMSG->wParam == VK_TAB || pMSG->wParam == VK_UP || pMSG->wParam == VK_DOWN )
        )
        return CExtResizableDialog::PreTranslateMessage( pMSG );
    else
        return CWnd::PreTranslateMessage( pMSG );
}

No, my grid is read only. It just happens if you select a row or the grid gets focus.

Dear Support,

What is the way to remove the caption bar of a dock bar completely?

Thanks,
Ron.

Dear Ron,

First of all, two notes about window/control names:

• Control bar (the CControlBar class in MFC) is the window which sticks to the border of its parent window and which can be optionally redockable in MFC frame windows. Status bar (the CStatusBar class in MFC, the CExtStatusControlBar class in Prof-UIS) is the most popular non-redockable control bar. Toolbars (the CToolBar class in MFC, the CExtToolControlBar class in Prof-UIS) and resizable bars (not implemented in MFC, the CExtControlBar class in Prof-UIS) are the most popular redockable control bars.
• Dock bar is also the kind of control bar, but it is internal window which has implementation both in Prof-UIS and MFC. The dock bar (the CDockBar class in MFC, the CExtDockBar and CExtDockOuterBar classes in Prof-UIS) is the non-redockable version of control bar which is designed to act as container for any kind of redockable control bars. I think dock bars normally should never be discussed.

All the control bars in Prof-UIS are created using the CExtControlBar::Create() method. Typically the control bar window styles specified in the method’s parameter are the default C++ parameter value which has several WS_*** standard window styles and several CBRS_*** MFC control bar styles. If the CBRS_GRIPPER style is present (it is specified in default parameter value), then:

• The gripper is present in created toolbar (the CExtToolControlBar class), menu bar (the CExtMenuControlBar class) or panel bar (the CExtPanelControlBar class).
• The caption is present in created resizable control bar (the CExtControlBar class).

So, you should simply create your resizable control bars with invoking the CExtControlBar::Create() method and specifying the set of styles similar to default C++ parameter value, but without the CBRS_GRIPPER style. Such kind of resizable control bar are very similar to the splitter windows, but they have two very handy features:

• You can show/hide them anytime at run time.
• Control bars have state persistence support.

Dear Support,

I am creating from scratch an SDI application. I create it to be maximized by default.
When i replace CFrameWnd with CExtNCW<CFrameWnd> i see that 4 right most pixels (the right side frame) is missing, as if the CExtNCW is doing some wrong calculations.

Is it a known bug? Do you want me to send you the project with the bug?

Regards,
Ron.

Dear Ron,

Please provide more details about the location of these 4 pixels on the screen. Do you use some multi monitor system? It would be very helpful to take a look at the screenshot demonstrating the problem?

Dear Sergiy,

Yes, i am using multi-monitor, in dual-view.
The extra pixels ’slide’ into the right monitor.

Regards,
Ron.

Dear Supporter,

I create a MDI API and enable tabbed MDI with "CExtTabMdiWhidbeyWnd" Class. Can’t I run time to add or remove the tabbed MDI effect ?

Thanks

Dear Support,

I’ve looked everywhere for a sample how to use OnGbwAnalyzeCellMouseClickEvent but I cannto find anyone.

I’ve got a CScrollSortGridWnd object which has to enable diferrent buttons when a row was clicked. So I have to ask for the left mouse click.

I tried it so:

//Header
CScrollSortGridWnd m_cTest;


//CPP

...
...
/* Add some rows*/
.....
.....



BOOL CPruefreihenfolge::PreTranslateMessage(MSG* pMsg)
{
if ( pMsg->message == WM_LBUTTONDOWN )
    {
    
    if ( this->m_cTest.OnGbwAnalyzeCellMouseClickEvent(VK_LBUTTON,1,NULL,NULL) )
        {
            MessageBox("jepp",NULL,MB_OK);
        }
    }

    return CExtResizableDialog::PreTranslateMessage(pMsg);
}


But nothing happens.

How can I get events that were send in my CScrollSortGridWnd object?

Thanks,

it works very well. ;-)


But now I’ve a new problem :-)

The choosen row was not selected. :-(

Just a guess: In Sergiy’s code it says:

	if( nColType == 0 && nRowType == 0)
	{
		// if we are here, then the inner data cell is clicked by the left mouse button
		if( "this event is handled by your code" ) return true;
	}

I think in your case "this event is handled by your code" should always be false, meaning that return shouldn’t be called here, only after CExtGridWnd::OnGbwAnalyzeCellMouseClickEvent.

Hello.

First of all, I hope it’s ok to lump more than 1 question into one thread. Please let me know if you’d rather they were separate threads. I have a bunch of GridWnd questions:

1. I have numeric cell columns that I do not want thousand separators for... is there a way to suppress the ’ThousandSeparator’ (i.e. a value of 345,543 to display as: 345543?

2. I am experiencing slow/choppy horizontal scrolling when using any of the office 2007 themes. I notice the grid sample in the ’Controls’ sample app seems to do a better job. I have tried to implement my grid the same way. The only differences I can think of are: My grid is on a CFormView and I have a lot more columns (160 for this app). Any thoughts on this?

3. Is there a thought about adding functionality for horizontal scrolling while dragging a column header to either end of the visible grid window? How could this handled programmatically? In other words, are there events I can use to get me going in the right direction?

4. The documentation help file (Very awesome, by the way!!) I have for 2.62, which I believe is the latest, is not up to date for the OnMeasureTextSize overridable. There are 3 CRect parms now in 2.63. What and how are they used?

5. Given a CExtGridCell pointer, is there a way to know the row and column?

6. I am trying with absolutely no luck to dynamically change the width of the Left Outer column (row headers). I have set the __EGCS_HDR_ROW_COLUMN_NUMBER style on the column of cells to auto number the rows. I want to dynamically change the Extent based on how many rows (largest width of all row numbers encountered). I have found examples here using OnMeasureTextSize for inner cells and column headers, but I can not get it to work for row headers.

Thanks very much for this tool. It is wonderful. The support is also very good. Keep up the great work.

1. CExtGridCellNumber class uses the information specified by the LCTYPE constant value LOCALE_STHOUSAND in the current locale. So you can use the SetLocaleInfo() method for changing this value. Please note you cannot specify the "" (empty) value using the SetThousandSeparator() method. This value is interpreted as the default value. Another way is to override the CExtGridCellNumber::OnQueryThousandSeparator( CExtSafeString & sVal ) virtual method and make the sVal parameter empty.

2. It is not clear what you mean by the "slow/choppy horizontal scrolling". If you mean the Office 2007 style of the scroll bars, please take a look at how it is done in the CMyGridWnd class in the ProfUIS_Controls sample (the PageGrid.h file)

3. This is not supported at the moment. We added this feature to our TO-DO list.

4. Thank you for the comments, we will update the documentation. These parameters were added for the future use and are not used currently.

5. The CExtGridCell object knows nothing about its location in the grid. The only one way is to traverse all the cells in the grid and compare the cell objects with your cell object. Please let us know where you are going to use the cell location? Maybe we could suggest you some better solution in your particular case.

6. There is a CExtGridBaseWnd::OuterColumnWidthSet() method that sets the width, in pixels, of the outer column on left/right.

This must be a simple problem, but for the life of me I can’t find the correct combination of styles. No matter what styles I select, I can always select multiple rows by holding down the Ctrl key. My current style is set like this:

    m_grid.SiwModifyStyle(__EGBS_SFB_FULL_ROWS, __EGBS_SFB_MASK);

The help docs say to enable multiple rows, I would need to include the __EGBS_SFM_ROWS flag. But I’m not including this and I can still select more than 1 row.

What am I doing wrong? This is with 2.62

Several questions about different grid cells:

1. How can I get an empty, but editable numeric cell? It seems that the cell it not editable until I assign a value, even 0, but then the value is displayed in the cell. I would like the cell to be empty until a value is entered.

2. How to change the format of the date in a CExtGridCellDateTime cell. It seems to be using the Windows short date format, how can I specify a custom format?

3. How to hide the None button on the pop-up calendar from the CExtGridCellDateTime cell.

4. How to get the top/left corner filled in. I have a top header and left header and would like a corner between the two. I’ve tried using __EGBS_EX_CORNER_AREAS_3D with the grid SiwModifyStyle, but it’s not working.

I didn’t need to override ::OnGbwEraseArea The code given didn’t draw the 3D look in the corners.
I used SiwModifyStyleEx (__EGBS_EX_CORNER_AREAS_3D to draw the corner

In addition to what Chris wrote we would like to add the following:

1. There is a new __EGCS_EX_EMPTY cell style that werer added in Prof-UIS v2.62 and it is exactly what you are looking for.

2. In the CExtGridCellDateTime::OnQueryDatePickerStyle() overridden method do not specify __EDPWS_BUTTON_NONE style.

3. The grid control does not display cell objects in corners but you can repaint them if you need to display some information there. You should override the CExtGridBaseWnd::OnGbwEraseArea() virtual method like as follows:

void C_YOUR_GridWnd::OnGbwEraseArea(
    CDC & dc,
    const RECT & rcArea,
    DWORD dwAreaFlags
    ) const
{
    ASSERT_VALID( this );
    ASSERT( dc.GetSafeHdc() != NULL );
COLORREF clrDebugFill = COLORREF( -1L );
    switch( dwAreaFlags )
    {
    case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_TOP:
        clrDebugFill = RGB( 255, 128, 128 );
    break;
    case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_BOTTOM:
        clrDebugFill = RGB( 128, 255, 128 );
    break;
    case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_LEFT:
        clrDebugFill = RGB( 128, 128, 255 );
    break;
    case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_RIGHT:
        clrDebugFill = RGB( 128, 255, 255 );
    break;
    case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_LEFT|__EGBWA_OUTER_TOP:
        clrDebugFill = RGB( 255, 128, 255 );
    break;
    case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_LEFT|__EGBWA_OUTER_BOTTOM:
        clrDebugFill = RGB( 255, 255, 128 );
    break;
    case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_RIGHT|__EGBWA_OUTER_TOP:
        clrDebugFill = RGB( 255, 255, 128 );
    break;
    case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_RIGHT|__EGBWA_OUTER_BOTTOM:
        clrDebugFill = RGB( 128, 128, 128 );
    break;
    case __EGBWA_INNER_CELLS:
        clrDebugFill = RGB( 255, 255, 224 );
    break;
    }
    if( clrDebugFill != COLORREF( -1L ) )
        dc.FillSolidRect( &rcArea, clrDebugFill );
}

Thanks for the reply I do have v2.62

Some comments for future reference:

1. For the empty cell, you still need to assign a value:
    pCellNumber->_VariantAssign (0);
    pCellNumber->Empty();

4. The __EGBS_EX_CORNER_AREAS_3D does work, but you need to use SiwModifyStyleEx, I was using SiwModifyStyle

1. I would like to create a similar layout as Microsoft did in Outlook’s Rules and Alerts (Tools->Rules and Alerts).

I would like to have a string of text be a link which would open up another dialog when clicked. I have looked through your examples and I see you are using buttons which I do not think will work in this case.

It is essential that I am able to make a few words in a sentence a link instead of the entire line.

This link would appear inside a CExtGridWnd cell.

2. Also is it possible to add another table inside a CExtGridWnd cell? So as to have a single cell be an entire new table.

Thank you for your time,
Darren

I apologize my quick example. The cell headers didn’t line up to their corresponding columns correctly.

Enable corresponds to <check box>
Action corresponds to "send e-mail to Parameter"
Parameter corresponds to "Jonny"

Thanks,
Keep up the great work!

Thank you for your quick response Sergiy.

I have redesigned my dialog by adding some colour to the grid cells to avoid a nested table. This allows me to show the entire grid without using a popup window. Thank you for the suggestion though :)

I am however still a little stumped on how to implement a rich text edit control. I would like a grid with check boxes on the left side corresponding to a line of text in the grid. I would like to underline one or more words in the cell but unfortunately I’m only able to underlne all the text in the cell.

Having check boxes would allow the user to enable or disable the corresponding action. A quick example would be
________________________________________________
Enable | Action | Parameter |
_____________|______________________|___________|
| <check box> | send e-mail to Parameter | Jonny |
_______________________________________________|

I would like to underline only the word "Parameter" where Parameter would just be a place holder for "Jonny". The underlined text wouldn’t be replaced with the text inside the parameter cell in the grid but the action would effectively be "send e-mail to Jonny".

The rich text examples you suggested look like they would work for a large single text control but could something like this be embedded inside a CExtGridWnd?

Thank you for your assistance,
Darren

The grid cell content you need is the simple text with multiple hyperlinks. Unfortunately we have no ready-to-use grid cell which is working as simple web browser. We can assume your message as feature request or custom work request depending on its importance in your project(s).

Hi tec support,
I’m starting a new project using CExtReportGridWnd.
I wish to hide some column when printing preview is enabled, is there a way to implement this?

Thanks a lot and Happy new Year
