I have a data grid with buttons in the cells (using __EGCS_BUTTON_ELLIPSIS). If I make a cell read-only, the button is disabled. I still need the button to work in these cells. How can I have an enabled button in a read-only cell?

We are not completely sure what result you are expecting to get but if you need a cell without inplace editor, the __EGCS_NO_INPLACE_CONTROL cell style can be more suitable than __EGCS_READ_ONLY.

Read-only cells come with an in-place editor, but it is read-only. In the case of the disabled in-place editor, it is not activated at all

pCell->ModifyStyle( __EGCS_NO_INPLACE_CONTROL );

Thanks for the info. I now have the button enabled, however clicking the button doesn’t work. I’m using CExtGridWnd::OnGridCellButtonPressed to detect and handle the button clicking, but this is not being called because CExtGridCell::OnClick checks if the cell is read-only. I don’t want to override OnClick for every cell type. How do I work around this?

1. How to make the CExtGroupBox text use the same color as the bar (like in the Controls sample). My CExtGroupBox controls have the text black.
2. Is the CExtGridWnd control suited for many rows, on the order of thousands? Will it be resposive when scrolling up/down, or when adding new rows and populating them? Some of the rows (few of them) will have the progress control activated in one column.
3. Is it possible to use the same progress control from the CExtGridWnd outside of the grid, instead of the default CProgressCtrl for example? Or in general, is it possible to use some of the controls demoed with the grid outside of the grid?
4. Is it possible to link a dll with the static version of the prof-uis libraries?
5. How to change the text size of a CExtLabel?
6. How to do a search on the forums for "all words". I tried AND but it didn’t seem to work - all queries seem to use OR by default, which means many irrelevant posts.

Thanks,

Adrian

The case I am using I am using a grid to replace a list-ctrl, because it is more powerful, and easier to do more than basic stuff.
Is there a way of making the grid appear like a list-ctrl? The main part which is different in appearance is the columns headers - they are quite different from the list-ctrl header (in XP).
There may be some other minor differences I haven’t noticed. I have used the styles etc to make it as much like a list-ctrl as possible.

Is there a way of making the selection behave the same way as selection in a list ctrl. E.G Ctrl enables multi-selection , but if you select an item that is already selected, it unselects. When using shift it selects every where from the initial selection to the last clicked item. If you click again with shift then it removes the previous selection before adding the new selection.
The case I am using is full row selection, and selection different rows.

This is the same behaviour we get in explorer.

Hi,

In an MDI project based on the document/view architecture, I have a child view class derived from CExtWA < CExtWS < CExtAFV < CFormView> > > class in a CExtControlBar.
I would like having my FormView stretch dynamically to entire client area of the CExtControlBar window.
I have tried this code but with no effect:

void CMyExtControlBar::OnSize(UINT nType, int cx, int cy)
{
    CExtControlBar::OnSize(nType,cx,cy);
    if(m_pView)
    {
        CRect rect;
        GetClientRect(&rect);
        m_pView->MoveWindow(rect);        

    
    }
}

Have you got an idea?

Hi,

I have a CExtGridCellColor in a property grid, and on initialization I am setting the color value to 7D9EC0, which maps to "LightBlue" in the preset color dropdown. If the user simply clicks within the cell and then immediately moves focus to another grid cell (i.e. no edit is made), the color in the grid cell changes to ADD8E6. The text still says "LightBlue" but is painted in bold text, indicating a change from default.

It seems that this is a problem with two colors mapping to an identical name (one a Web color, the other an Office color). Presumably the RGB->text pulls one of these first out of the lookup map, and text->RGB pulls the other first. This could happen with other colors too I imagine.

For me this isn’t a major issue as I’ve just changed the default color and I’m hoping users never encounter the problem, but I believe the mapping should be consistent, otherwise it looks like a bug.

Thanks.

When I implement a CExtGridCellComboBox and populate it, if you type in a letter to go to an item nothing happens. In searching this forum it looks like it is supposed to work like a regular combo box and select the first item with that letter. This is true in the sample prof uis controls also. I am using version 2.80. Is there something I need to do to make this work? I overroad the function that is supposed to perform this operation and the message WM_CHAR never fires.

The feature is implemented. Now when the user is typing a letter something and the focus is on a combo box cell or the popup list box is visible, the corresponding item whose text begins with this letter is selected. If there are several items with text beginning with the same letter, they are selected cyclically. This behavior is identical to that in the standard combo box.

Please update the source code for the CExtGridCellComboBox class. Add the following method declaration

virtual bool OnKey(
	CExtGridWnd & wndGrid,
	bool bKeyDownEvent, // true - key-down event, false - key-up event
	UINT nChar, // virtual key code

I have found that screen tips shadows are not cleared if the screen tip is not fully drawn. This is an extract from my user’s report:

hover over a ribbon bar button. After about a second or two, the screen tip fades up quickly. If you pull your mouse away just as its fading up (you’ve only got a fraction of a second !), you end up with the outline of the screen tip as a shadow that doesn’t go away. The shadow even stays on top when you have other applications’ windows on top

I have a dockable control bar which is docked with a main CExtTabPageContainerWnd. Now when I open another OCX is loaded onto my main application, the entire application gets refreshed. It is now that the dockable control bar gets vanished because the docking code had been written in the oncreate() method and this is called only once during the startup of the application. Could you please let us know what could be the reasons?

I have a Mainframe for my main app called saisd. I have a dockable control bar called "binsbar" that is created inside the OnCreate() of MainFrame. Inside the Mainframe I have CExtTabPageContainerWnd called the ChildView. This child view class has three tab pages.

At runtime when I drag a so called "transform", the new toolbars and menubars in the mainframe are loaded. Also these transforms have a new mainframe of theirs. So when they get loaded the docked bins bar vanishes as of course it was created and docked with the original mainframe of the application not the one that we loaded just now. However if I have done an auto hide, then I can see the binsbar at the side. Please let me know if I can dock my controlbar at the available mainframe rather than the one which was originally created.

Please treat it with utmost urgency.!

A mail was sent yesterday with screenshots but we have not recieved any updates yet

My application allows customization with unmodified keyboard accelerators, using the __ECSF_ALLOW_UNMODIFIED_ACCELERATORS flag. This is so a Photoshop style tool selector can use a single keypress to select a tool.

When a CExtEdit has focus, these keys cannot be typed into the edit, since they trigger the accelerator command.

Is there a way to stop the accelerators when CExtEdit has focus? Thanks.

I replaced CExtResizableDialog with CExtNCW < CExtResizableDialog > as base class for my app’s dialog, and now when I start it up, it always gets positioned in the top left corner of the screen, instead of in the middle. Any easy fix for this?

Thanks.

Adrian

Calling CWnd::CenterWindow() fixed the problem.

Thanks,

Adrian

We are not sure that the DLL project type affects this problem. Please ensure you have specified the correct parent window for the dialog when invoking its constructor. Please also let us know what happens when you invoke the dialog’s CWnd::CenterWindow(). If you send us a test project, that should help us find out what’s wrong. But first, would let us take a look at the dialog’s creation code?

Please check if this can be reproduced with our dialog-based applications (e.g. ProfUIS_Controls and IconEditor), which are also based on CExtNCW < CExtResizableDialog > . If not, could you send a project that demonstrates the problem?

I have a dialog whose code is in a dll. I’m trying to add a toolbar using CToolControlBar but I can’t get the different buttons to show. Here’s what I get:

http://www.amichel.com/toolbar/toolbar.jpg (BTW, how to you insert an image in a post? I tried with but that didn’t work).

Some buttons show when I click the arrow at the right, but they are disabled (this has to do with command handlers though). The first several buttons don’t show here as though there were already on the toolbar.

Second, is it possible to add any controls to this toolbar? For example, I need to add a date/time control with a button to bring up the calendar control - how can I do that?

Thanks,

adrian

It turns out I wasn’t calling the required command manager methods to handle profiles - I’m calling them now and the toolbar is working fine.

Thanks for your help,

Adrian

First of all, please ensure CWnd::RepositionBars( 0, 0xFFFF, 0 ); is invoked after toolbar buttons are initialized. Second, you can send us your dialog’s source code so we will clarify what may be wrong.

I had already done that ( the call to RepositionBars) but it didn’t make any difference. I think my first image was misleading - it was not about the toolbar size or position (see this image http://www.amichel.com/toolbar/toolbar.jpg ), regardless of the toolbar size, no buttons are displayed there. But it looks like internally the code things the buttons are there as I explained in my first message.

Regarding the second question, I already read that article, but I could not experiment with this feature because I couldn’t get any buttons to show. I’ll try that when I get this first issue fixed.

Thanks,

Adrian

A CExtToolControlBar toolbar created inside a dialog cannot be dockable. So your dialog is responsible for positioning such a toolbar near a dialog side. The code CWnd::RepositionBars( 0, 0xFFFF, 0 ); placed at the end of dialog’s OnInitDialog() and OnSize() methods do that and resizes the toolbar so it displays the maximum possible number of buttons.

As for your second question please read the How to insert controls into the toolbar?.

We are sorry but you cannot use the <img> at the moment. We will fix it soon.

I would like a slider that represents a range of values rather than just one.

Therefore, say the min/max were 0-100. Once I move the slider from 0 up, a painted bar follows the slider upward similar to a progress bar.

That way, it is clear to the user that all values from 0 to the slider bar are included.

Do you have this. I don’t see it in the docu.

Dear Support,

In our non-customizable application we are using a color selection button in the toolbar. I’d like to make the button reflect the currently selected color in its icon. Unfortunately all of your samples which uses the color selection button are customizable, so probably this is the reason you haven’t encountered the problem I have: When the application is non-customizable, CExtBarColorButton::ColorGet is reduced to the following code:
return bSelected ? m_clrDefault : m_clrSelected;

As you can see, this produces the default color when it should produce the selected one. Because of this, OnSyncIcon sets an icon with the default color and not with the selected color, as it should.

Please, check this issue! Thank you!

If you click the color area of a CExtBarColorButton toolbar button, the classic WM_COMMAND message with color button’s identifier will be sent. The command handler method should access the CExtBarColorButton object to get its color value and apply it to something in your project. If you click the drop-down arrow, then the CExtPopupColorMenuWnd color popup menu is displayed and you should handle its notification messages (CExtPopupColorMenuWnd:: g_nMsgNotifyColorChangedFinally).

We confirm this typo in the CExtBarColorButton::ColorGet() method. In fact it should be

COLORREF CExtBarColorButton::ColorGet( bool bSelected ) const
{
      ASSERT_VALID( this );
#if (!defined __EXT_MFC_NO_CUSTOMIZE)
const CExtToolControlBar * pBar = GetBar();
CExtCustomizeCmdTreeNode * pNode = ((CExtBarButton*)this)->GetCmdNode(false);
      if(         pNode != NULL
            &&    pBar->GetSafeHwnd() != NULL
            &&    ::IsWindow( pBar->GetSafeHwnd() )
            )
      {
            ASSERT_VALID( GetBar() );
            ASSERT_VALID( pNode );
            CExtCustomizeSite * pSite =
                  ((CExtToolControlBar *)GetBar())->GetCustomizeSite();
            if( pSite != NULL )
            {
                  COLORREF clr = bSelected ? m_clrSelected : m_clrDefault;
                  if(   pSite->OnColorItemValueGet(
                              (CExtBarColorButton*)this,
                              pNode,
                              clr,
                              bSelected
                              )
                        )
                        return clr;
            } // if( pSite != NULL )
      }
#endif // (!defined __EXT_MFC_NO_CUSTOMIZE)
      return bSelected ? m_clrSelected : m_clrDefault;
}

How can I get the grid to show ###’s instead of a number for a cell that is too narrow to show the entire number, as Excel does?

Dear Tech Support
As mentioned in my last question our MDI application consists of a main frame e.g. CMainFrame and several different child frames e.g. CMDIChildWnd. http://www.prof-uis.com/Forum_View.aspx?CID=40&M=57803

I am using the g_CmdManager to organize all the Toolbar and Menubar handling. I’ve been having problems while serializing to and from the registry due to missing ID’s. This problem should be solved by know but in order to do this I had to get a closer look at the samples programs and this support form.

Unfortunately I am still a bit uncertain whether I am using the command manger in the right way. Looking at all the samples and forum threads did not give me a somehow consistent picture of the command manager.

At the moment I use in the OnCreate method of the MainFrame ProfileSetup -> ProfileWndAdd -> UpdateFromMenu -> UpdateFromToolbar -> SerializeState. In the DestroyWindow I use SerializeState -> ProfileWndRemove. This seems to work fine but I have seen examples where each child window is also being registered. If I try to do this I am starting to have problems with the dock able toolbars of the child windows. As soon as they are floating they are either gaining or losing text and pictures which I have assigned to them with g_CmdManager->CmdGetPtr -> pCmdItem->m_sToolbarText = string.

What is the common way with an MDI application? Only register the mainframe or do I also need to register the child frames. Our application comes closest to the MDI_InnerOuterBars sample application. One thing I do not understand about the MDI_InnerOuterBars application is why they use the ProfileWndRemove() in the ChildFrame::DestroyWindow(). I cannot see that this child window ever gets registered.

(in 2.7 - you may have fixed it in 2.8 I haven’t checked yet)
When I use CExtGridCellObjectSize in a data grid, without changing any settings, it removes ’0’ (zeros) when it shouldn’t.
For example if the size should be 90 KB it displays this as 9 KB. (the original number is 92160, with units set to "KB")

It does this when m_bAllowTrailingZeroes is set to true (the default is "true" in CExtGridCellNumberBase). This variable should be set to true but it seems that the call to OnQueryTrailingZeroes() is used incorrectly in "CExtGridCellObjectSize::TextGet" - it trims any zeros, not just ones after the decimal separator.
The implementation of TextGet in CExtGridCellNumberBase seems to have the correct behaviour in regards to the usage of OnQueryTrailingZeroes().

Even with ProfUIS 2.8 I am still facing DebugAsserts in my Debug Setup when ever I move the mouse over the Scroll arrow in the CExtTabWnd.
What could be the resolution to this.

One more thing is Enabling ToolTips also causes unavoidable DebugAsserts in the Debug Setup for tab pages in CExtTabWnd.( Not found in release)

My working on Debug Setup is very difficult.Kindly suggest ASAP. This is very urgent

Can you let me know the handler for this?

The CChildView window is the parent for the CYourTabWnd window. So you should invoke the following code in the OnTabWndClickedItem() method

GetParent()->SendMessage( . . .

class CChildView : public CExtTabPageContainerOneNoteWnd
{
     class CYourTabWnd : public CExtTabWnd
     {
protected:
virtual bool OnTabWndClickedItem(LONG nItemIndex,bool bButtonPressed,INT nMouseButton,UINT nMouseEventFlags)
{
bool bRet = CExtTabWnd::OnTabWndClickedItem(nItemIndex,bButtonPressed,nMouseButton,nMouseEventFlags);
            //CSaIsDoc * pDoc = (CSaIsDoc *)((CSaIsMainFrame*)GetParentFrame()->GetActiveDocument());
        if(nItemIndex > 2)
         {
if ( nMouseButton == MK_RBUTTON )
             {
                 //GetPresentationView()->SendMessage(WM_SAIS_SINK_TAB_RIGHT_CLICKED,0,nItemIndex);
                    //CChildView::GetMessageForPresentationView(nItemIndex);
}
            }
return bRet;
}

        

};
virtual CExtTabWnd * OnTabWndGetTabImpl()
{
return new CExtTWPC < CYourTabWnd >;
}
    
I have a query... I wanto send a message to the CSaIsPresentationView class which has an object as a member of CChildView . But in this nested declaration that you have suggested me, it seems difficult to do...

Please respond..Its very urgent.!

This method is required to make the tab page container use the CYourTabWnd control inside it instead of CExtTabWnd that is used by default. This is a very important method because tab item clicks are handled in the CYourTabWnd class.

virtual CExtTabWnd * OnTabWndGetTabImpl()
{
return new CExtTWPC < CYourTabWnd >;
}

Is this part required? If yes then what for

Yes, it’s needed. Every CExtTabPageContainerWnd-derived object uses a built-in CExtTabWnd-derived object (the tabs with which users can switch between pages). OnTabWndClickedItem is method of CExtTabWnd class, so you have to override it in a CExtTabWnd-derived class. With the above OnTabWndGetTabImpl method you make your TabPageContainerWnd class use your TabWnd-derived object. If you don’t override it, the TabPageContainer will use the default tabwnd implementation, not yours.

Hi Support,

I try to remove multiple pages from the CextTabPageContainerWnd. using the method PageRemove(Idex,no.from index,TRUE). But this crashes in both ProfUIS 2.54 and 2.80 . Any pointers into what may be going wrong.

If I do single pageRemoval in a loop, this works fine.

One more query is : Can I Remove a page from the TabPageContainerWnd and not select the previous tab by default. i.e. if i remove the page with index 9, i donot want the 8 to be selected.Can it be done?

Please suggest ASAP.

Thanks

We tested the CExtTabPageContainerWnd::PageRemove() and found no problems with it. But anyway we have changed this method to make it safer. So now any crashes are simply impossible.

Here is the modified code:

LONG CExtTabPageContainerWnd::PageRemove( 
	LONG nIndex,
	LONG nCountToRemove, // = 1
	bool bDestroyPageWnd // = true
	)
{
	ASSERT_VALID( this );
	if( nIndex > m_pWndTab->ItemGetCount() - 1L )
		return 0L;

LONG nCountRemoved = 0L; // returns count of removed items

LONG nCount = m_pWndTab->ItemGetCount();
LONG nAvailToRemove = nCount - nIndex;

	if( nCountToRemove > nAvailToRemove )
		nCountToRemove = nAvailToRemove;

	for( LONG i = 0L; i < nCountToRemove; i++ )
	{
		HWND hWnd = (HWND) m_pWndTab->ItemLParamGet( nIndex );
		if(		hWnd != NULL 
			&&	::IsWindow( hWnd )
			)
