Dear Support,

We’ve been having sporadic crashes in this function when loading UI states for a long time, and we think that we understand the reason, but we still need your help to realy understand what is happening.

This is the location of the crash in the function CExtCmdProfile::SerializeState, lines 1860 onwards:

            ...
            for( ; true; )
            {
                UINT nCmdId, nUsageTickCount;
                ar >> dwTmp;
                nCmdId = UINT(dwTmp);
                if( nCmdId == 0 )
                    break;
                ar >> dwTmp;
                nUsageTickCount = UINT(dwTmp);
                CExtCmdItem * pCmdItem = CmdGetPtr(nCmdId);
                ...

We see that this happens when the application was running and the user selected a command from a popup menu, this command, for some reason was saved in the serialized data, and the next time we load the application, it crashes.

We updated the function to skip these commands:

                if (NULL==pCmdItem)
                {
                    continue;
                }

Can you please explain why this happens?

Thanks,

Ron.

Yes, this NULL checking code is only the not to crash solution. You should check whether the command manager is really updated from all the toolbar and menu resources in your project. Additionally, if you are registering/allocating some of command identifiers manually at run-time, then you should mark these commands as basic commands.

Please ensure you updated the command manager from all the menu and toolbar resources used in your application before loading command states. There is the common error is related to context popup menus based on menu resources: if you forgot to update the command manager from such menu resources, then it’s become updated later during menu initialization. This means command manager state loading and saving operates with different counts of registered commands. We added the NULL checking condition but we also left the NULL assertion.

I’m sure I’m doing something wrong.  I hope you can give me a clue as to what it might be.

My appilcation open and closes some windows whose parent is the the desktop window.  These windows are destoryed before the main view is destroyed.

During the application shutdown I get an ASSERT at this point on the stack:

It appears to me that the main window is being destroyed at this point.  message 274 is WM_SYSCOMMAND and message 130 is WM_NCDESTROY.  The assert if becasue the handle of CFrameWnd::m_pViewActive is 0xfeeefeee.  So it appears the view has been destroyed.

Any idea what I might be doing (or NOT doing)?

The active view is the term related to MFC’s document view architecture rather than to to the windowing system displayed on the desktop of the Windows OS. We suspect you created some views manually and some of them become marked as active. You can invoke frame’s CFrameWnd::SetActiveView(NULL) method at shutdown. You can set breakpoint inside this method and try to find out which views become active in your application and when.

Thanks for your help.

Your suspicion was incorrect.  I only use a single view.  It gets set at the start of execution.   That’s the only call to SetActiveView().

But your suggestion solved the problem.  It tried overriding DestroyWindow() for the view but that never gets called.  So I added this to the view desctructor:

 CFrameWnd* pFrame = (CFrameWnd*)AfxGetMainWnd();
 if (pFrame->GetActiveView() == this)
  pFrame->SetActiveView(0, FALSE);

That fixed it.  The MFC framework should probably be doing this but isn’t.  I can only wondow why no one else has run into this.

Again, thanks.

Dear Support,

I have items that do not fit in the width of the drop list.

How can I make the drop list inherit the width of the cell?

Thanks,

Ron.

You should implement the CExtGridCell::OnPopupListBoxMeasureTrackSize() virtual method. Or, we can provide you with the latest Prof-UIS 2.85 which does the popup list box size computation using sizes of all its items.

Dear Support,

I have s requirement to be able to change the font size, which will change all font sizes in all my application.

Does Prof-UIS support such a thing?

Thanks,

Ron.

Dialogs are loaded from dialog template resources. If you have two or more localized versions of some dialog, their dialog templates contain different localized window texts of dialog controls. As a result, the text length can be very different in each localization and affect to size and position of dialog controls. That is why dialogs and form views should be re-created if you need on-the-fly language changing.

Thanks for the explanation.

1) Do you have a sample of how this is done?

2) What will happen with the Prof-UIS grids? Will they inherit the font size of the dialog, or do I need to set this one manually?

3) What will happen with all other controls like CExtLabel, CExtEdit? do they all derive from the font defined in the dialog template, or are there any exceptions?

Ron.

We do not have such sample. But this task is not difficult. Just destroy dialogs using the CWnd::DestroyWindow() method or ::DestroyWindow() Win32 API and create the again. The grid controls does not use the parent window font. They always use font provided by the CExtScrollItemWnd::OnSiwGetDefaultFont() method. If the dialog window assigns its font to the child grid window, then you will see dialog font in this grid. If not, then the grid window will use the paint manager’s font which is typically the same as the default font for dialogs. The common controls dropped into dialog template resource will use the dialog font.

The FunnyBars sample application does this on the fly.

Dear Support,

I have a tag container in a control-bar or a view, that contain several dialog derived from CExtResizableDialog. When the user resize the window so that it’s smaller then the dialog initial size, I need to have a scroll-bar so that thew user will be able to scrol to th bottom part of the dialog.

How can this be done?

Thanks,

Ron.

You should create a CExtScrollContainerWnd window and then create a child dialog inside it:

Dear Support,

The sample does not compile with 2.84, can you please check why?

We are sorry for the inconvenience.

Before Prof-UIS 2.84: the CExtScrollContainerWnd class was the part of this sample project.

In Prof-UIS 2.84: the CExtScrollContainerWnd is present inside Prof-UIS.

So, the old and test version of the CExtScrollContainerWnd
class should be simply removed from this test project. Please download the updated version:

Dear Support,

Ignore the crash report - I was doing a wrong cast - Now it works

However, I have one small question:

When I use the arrow buttons of the scroll bars, it goes pixel by pixel, which is not very effective - how can I cahnge it to be, say 20 pixels each press?

Thanks,

Ron.

Please set the CExtScrollBar::m_nStepSize property to 20.

Did not work. I changed my code as follows:

    CExtScrollContainerWnd* pScrollPageContainer = new  CExtScrollContainerWnd;

    CRect rc;
    m_pTab->GetClientRect(rc);
    pScrollPageContainer->Create(m_pTab, rc);
    pScrollPageContainer->m_wndScrollBarH.m_nStepSize = 20;
    pScrollPageContainer->m_wndScrollBarV.m_nStepSize = 20;

    pPage->Create(nID, pScrollPageContainer);
    pScrollPageContainer->SetPage(pPage);
    m_pTab->PageInsert(pScrollPageContainer, pPage->GetName());

And still, the arrows move it pixel in each iteraion, and not 20.

Dear Support,

There is one more twist in my situation - the dialog is embedded inside a tab container. So I tried to add the page like this:

   pwndScrollContainer = new CExtScrollContainerWnd;

   CRect rc;
   m_pTab->GetClientRect(rc);
   pwndScrollContainer->Create(m_pTab, rc);
   pPage->SetView(this);
   pPage->Create(nIDD, m_wndScrollContainer);
   m_pTab->PageInsert(wndScrollContainer, "My Page");

What am I missing?

Thanks,

Ron.

The source code snippet looks correct. The call stack listing is incomplete. We suspect the code snippet in your message is invoked under some WM_CREATE message handler what causes conflict with MFC’ window creation hooking. Please try to initialize the tab pages with delay or send us a test project demonstrating this crash.

Hi,

i have a problem with the PropertyGrid. When i choose an item from a  combobox, then the text, that will be displayed, is changed but not in bold. In the Apply-function i can retrieve with GetCurSel only the old value. Only when i highlighted the text and choose a secound time an item from the combobox, then GetCursel gives me the new value.

I send you yesterday an example per mail.

Please tell me what’s wrong.

Ulrich

We still didn’t receive any e-mail from you.

We compiled and run the test project you sent us. If we change the ’Aussehen’ property, then it becomes bold. The result message box displays new theme index each time. If we open the options dialog with the property grid inside second time, then the ’Aussehen’ property displays old theme value. This happens because the COptionDlg is reconstructed again and its m_Values contains constructed by default property tree. This is not correct. We think the property store should be kept somewhere outside the options dialog or the COptionDlg class instance should not be re-created in the COptionDialogDlg::OnBnClickedSettings() method each time you need to display this dialog.

I have two docked windows.  Programmatically I have computed the sizes I want for them, and have set the size for both CExtDynamicControlBars via SetInitDesiredSizeVertical. I then dock each bar using:

virtual bool DockControlBar(

UINT nDockBarID,

UINT nCircleNo,

CFrameWnd * pDockSite = NULL, // can be NULL only if bar already was at once docked

bool bRecalcLayout = true

);

This appears to work fine, docking both to the left in cirlce 1, resulting in something like this:

|-------------------|

| Window One |

|-------------------|

| |

| |

| |

|-------------------|

| Window Two |

|-------------------|

| |

| |

| |

|-------------------|

However, if I minimize the app, then restore it, the docked windows rearrange themselves to this:

|-------------------|

| Window One |

|-------------------|

| Window Two |

|-------------------|

| |

| |

| |

| |

| |

| |

| |

|-------------------|

How do I prevent this behavior from occurring?

Kevin Murray, AGI

We suspect you simply forgot to invoke the main frame’s RecalcLayout() method after docking each bar.

I tried both of those methods. 

DockControlBarInnerOuter won’t let me dock in the same place as an already docked window.

DockControlBarLTRB will let me dock in the same space, but only works well with two windows.  If I have three windows, for example, I cannot seem to get them to space evenly.  For example:

pBar1->DockControlBarInnerOuter(...);

pBar2->DockControlBarLTRB( 33, pBar1 );

pBar3->DockControlBarLTRB( ..., pBar1 ); // <-- regardless of percentage, always docks the same way

How do I properly dock x bars to the same side evenly using DockControlBarLTRB?

Kevin Murray

I have a modeless CExtResizableDialog with a CExtToolControlBar.  It works fine when the dialog’s parent is AfxGetMainWnd() but I want the dialog to be behind the main window when the main window has focus.  To do this I changed the parent to CWnd::GetDesktopWindow().  But then the buttons are blank.  (They work but the images aren’t there.)

Here’s what I do in OnInitDialog()

 m_wndToolBar.LoadToolBar(IDR_DOXLST_BAR);
 RDrwDpiGet(&nDpiX, &nDpiY);
 ::SetRect(&rectWork, 0, 0, (int)(2.25*nDpiX), nDpiY);
 VERIFY(m_cmbBarDrag.Create(
   WS_CHILD|WS_VISIBLE|WS_TABSTOP|CBS_DROPDOWNLIST|CBS_HASSTRINGS,
   rectWork, &m_wndToolBar, ID_DOXLST_CMB_DRAG));
 VERIFY(m_wndToolBar.SetButtonCtrl( 
   m_wndToolBar.CommandToIndex(ID_DOXLST_CMB_DRAG), &m_cmbBarDrag));
  m_wndToolBar.m_bForceBalloonGradientInDialogs = true;

And then this in DoDataExchange()

 DDX_Control(pDX, IDR_DOXLST_BAR, m_wndToolBar);

Those are the only refernces to the toolbar

You should invoke the g_CmdManager->ProfileWndAdd( pszProfile, pDialog->m_hWnd ); code in the beginning of the dialog’s OnInitDialog() virtual method. You should invoke the g_CmdManager->ProfileWndRemove( pDialog->m_hWnd ); code in the beginning of the dialog’s OnOK() and OnCancel() virtual methods.

Thanks.

Actually I overrode DestroyWindow() and called ProfileWndRemove() there so it’s called when the window is closed.

Hi,

I want to display a CExtComboBox in a toolbar (already done), but instead of displayed a string list, I want to display a checkbox with string list. Is it possible ?

Thanks.

Thanks for your update but two things :

1. When clicking on the arrow to "drop-down" the combo box content, the height of the visible items seems to be null (the width is correct). If I replace my CExtCheckComboBox by a CExtComboBox, it is ok. Here is the Create() line:
   
   if (m_wndComboZones.Create(WS_CHILD | WS_VISIBLE | WS_TABSTOP | CBS_DROPDOWNLIST | CBS_HASSTRINGS, CRect(0, 0, 150, 100), this, ID_TOOLBAR_COMBO_ZONES) == FALSE)
   
   
   
   So I cannot view my items, neither check/uncheck them.


2. The CExtCheckComboBox::ResetContent() does not works (or maybe CExtCheckComboBox::m_strText is not updated).

Thanks.

The CExtCheckComboBox class currently requires the CBS_DROPDOWNLIST|CBS_OWNERDRAWVARIABLE|CBS_HASSTRINGS styles. Please specify the CBS_OWNERDRAWVARIABLE style.

Thank you for reporting the content resetting issue in the new check combo box control. To fix it, please update the source code for the following method:

LRESULT CExtCheckComboBox::WindowProc( UINT message, WPARAM wParam, LPARAM lParam )
{
            if( message == CB_RESETCONTENT )
                        m_bHaveItemHeight = m_bHaveText = false;
            else
            if(                     WM_KEYFIRST <= message && message <= WM_KEYLAST
                        &&        ( wParam == VK_UP || wParam == VK_DOWN || wParam == VK_LEFT || wParam == VK_RIGHT || wParam == VK_PRIOR || wParam == VK_NEXT || wParam == VK_HOME || wParam == VK_END )
                        )
            {
                        if( ! GetDroppedState() )
                        {
                                    ShowDropDown();
                                    return 0L;
                        }
                        SetRedraw( FALSE );
                        LRESULT lResult = CExtComboBox::WindowProc( message, wParam, lParam );
                        SetRedraw( TRUE );
                        Invalidate( TRUE );
                        UpdateWindow();
                        return lResult;
            }
            return CExtComboBox::WindowProc( message, wParam, lParam );
}

I added the CBS_OWNERDRAWVARIABLE flag, but it didn’t solve my problem. I sent to you by email a quick and short sample (Visual C++ 6.0) which demonstrate my problem. May be something is wrong on my side.

Thanks for your support.



You reported a very interesting issue. The check combo box does not have such issue when created inside dialog window. We found only temporarily but working solution for this issue. Please download the fixed version of your test project and find all the comments in it marked with the PROF-UIS TECH SUPPORT text:

http://www.prof-uis.com/download/forums/tmp/TestCExtCheckCombo-fixed-for-EmmanuelVERGUET.zip

Another things, I discover that you are using ItemData to store checked state. I planned to use this ItemData to store something else. Is it possible to not use the ItemData to store checked state ? If not possible, I will create a map.

Thanks.

We can implement check marks in the synchronized CArray object. But if you are going to use the CMapStringTo*** object for storing your data linked to the combo box items, then please note all the combo box strings should be unique.

Thanks for your update.

So, in next release v2.85, I will need to rooback this patch ?

If we find a solution to avoid additional moving of the check combo box window, you can remove this trick from your project. But it does not conflict with the combo box control and even if you leave it, then it will work.

I’m not using customizable toolbars and menus. And yes, CExtGridCellCheckListComboBox is the control that fit my needs, but now, how can I add this control in my toolbar. Like a CExtComboBox ?

Thanks.

Please update the …/Prof-UIS/Include/ExtComboBox.h and …/Prof-UIS/Src/ExtComboBox.cpp files from the following ZIP file and re-build required configurations of the Prof-UIS library.

http://www.prof-uis.com/download/forums/tmp/NewCombo285.zip

Now the new CExtCheckComboBox class is ready for use in your project. There are only three interesting methods in this class because they work with a set of check boxes:
void CheckSet(
INT nIndex,
bool bCheck = true
);
bool CheckGet( INT nIndex ) const;
void CheckAll(
bool bCheck = true
);


Dear Support,

I have a dialog with grids, and I added them to the tab order. When I walk through controls with the tab key, I know that the grid gets the focus, becuase I then can navigate in rows using the up & down keys, and edit with the F2 key etc. however, there is no visual clue that the grid got the focus, the select cell is not coloreed in the focus cell color for indication.

Is there a way to fix this?

Thanks,

Ron.

You need two things to avoid such invisible focus effect:

1) Do not forget to setup focused cell/row/column during grid initialization.

2) Handle the WM_SETFOCUS message in your grid class and check whether the CExtGridWnd::FocusGet() method returns negative row/column indices and invoke the CExtGridWnd::FocusSet() method to set focus on cells which you like.

The grid window highlights the focused cell with the standard dotted focus rectangle. This focus rectangle is displayed only when the grid window is focused. The selected cell(s) (or row(s), or column(s)) are highlighted using the standard COLOR_HIGHLIGHT Win32 color for painting selected background. This color is used only when the grid window is focused. It’s possible to make the selected grid cells highlighted COLOR_3DSHADOW color when the grid window is not selected. This can be done by applying the __EGBS_NO_HIDE_SELECTION using the CExtScrollItemWnd::SiwModifyStyle() method. So, the selection and focus highlighting in the Prof-UIS grid windows are implemented exactly like in Win32 controls. We suspect you initialized your grid window but didn’t set focus/selection to some cell(s) (or row(s), or column(s)).

Dear Support,

I have a grid with row & column header and top & left. The right & bottom sides looks as if they miss the frame that the top & left sides have. Is there an option to add those?

Thanks,

Ron.

Dear Support,

If I will add the scroll bars, I will have scroll-bars... I just want the lines to continue so it won’t look like something is missing.

Thansk,

Ron.

You should apply an appropriate set of the __EGBS_BSE_EX_EAL_*** styles using the CExtGridWnd::BseModifyStyleEx() method or the CExtGridWnd::GridEmptyAreaLines***Set() methods.

Dear Support,

This is not what I askded for - what I need is for the frame of the grid to continue on the right edge and on the bottom edge, and for that matter on every edge that does not have header cells.

Unless you have header rows on all sides, it looks as if the grid is not finished, as you can see in the screenshot above.

Completing the internal area with grid lines will only confuse our users thing that there are cells there, when there actualy are no cells.

Thanks,

Ron.

Dear Support,

I have a grid which I override OnSiwPaintBackground and paint it in the dialog’s color:

void CMyGrid::OnSiwPaintBackground(CDC & dc,bool bFocusedControl) const
{
    ASSERT_VALID( this );
    CExtGridWnd::OnSiwPaintBackground( dc, bFocusedControl );

    CRect rcGridInner = OnSwGetClientRect();
    if( ! dc.RectVisible( &rcGridInner ) )
        return;

    bool bFillArea = true;
    if( g_PaintManager->GetCb2DbTransparentMode( (CWnd*)this ) )
    {
        if( g_PaintManager->PaintDockerBkgnd( true, dc, (CWnd*)this ) )
            bFillArea = false;
    } // if( g_PaintManager->GetCb2DbTransparentMode( (CWnd*)this ) )
    if( bFillArea )
    {
        COLORREF clrFill =
            g_PaintManager->GetColor( CExtPaintManager::CLR_3DFACE_OUT, (CObject*)this );
        dc.FillSolidRect( &rcGridInner, clrFill );
    } // if( bFillArea )
}

    pCell->ModifyStyle(__EGCS_READ_ONLY);

Is this a bug? if not, what do I need to do so that the bakc color of this cell will not change when it’s read-only?

Thanks,

Ron.

You can invoke the CExtGridCell::TextColorSet() method for all your grid cells when you inserting them into the grid window. You should use the CExtGridCell::__ECS_READ_ONLY color type to change only the read-only text color of your grid cells. This is the first solution. The second solution is to implement the CExtGridCell::OnQueryTextColor() virtual method in your grid cell classes. The third and the most convenient solution is to implement the CExtGridWnd::OnGridCellQueryTextColor() virtual method in your grid control class. The CExtGridWnd::OnGridCellQueryTextColor() virtual method can return the COLORREF(-1L) value if you want the grid cell to compute its text color using default color selection algorithm. This virtual method should analyze whether the grid cell has the __EGCS_READ_ONLY cell style and return the desired text color for it.

I don’t understand why it works for normal cell, the background is painted with color function of CMyGrid::OnSiwPaintBackground, but when the cell is disabled it does not - why can’t I tell the cell to not paint its back-color in the same way it does not do it if the cell is not read-only?

Please implement the CExtScrollItemWnd::OnSiwGetReadOnlyBackgroundColor() virtual method and return the COLORREF(-1L) value from it.

Dear Support,

We have an an application, that sometimes get stuck when switching tabs. Can you please look at the stack and see if you can figure what can cause it? It seems to never exit ProfUIS’s hooks as you can see below.

Thanks,

Ron.

You may try to set WS_EX_CONTROLPARENT extended style to your tab : http://blogs.msdn.com/oldnewthing/archive/2004/07/30/201988.aspx

Thanks Dan!

Seems to solve the problem.

Dear Support,

There is another problem - if I do not set the control attribure to true, and I come back to the first tab, the control with the focus in the sub-dialog (if it’s a text box) is not drawn correctly (it’s content is not drawn)

I will send you a sample application that reproduces this bug.

Regards,

Ron.

Keyboard navigation with a minimized ribbon bar shows the wrong tab selected.

Try the ribbon bar MDI sample.  Hit Alt and hit a key as shown under the ribbon tabs.  If the bar is minimized, then the appropriate page is shown, but the wrong tab is selected above it.

Thanks,

Rob.

How can I use a raised-style button on a ribbon bar?  Typically they are flat, and all you see against the background is the button’s icon and text.  How can I make a button actually look like a button, like those in the ProfUIS Controls demo?  I’m (mostly) using Office 2007 themes.

Thanks,

Rob.

Dear Support,

I have a CExtLabel derived class, in which I want to know the exact size of the text in the control, so that I can add my drawing after the text.

The way to do it is by using DT_CALCRECT as you well know. I tried to pass to OnDrawLabelText all the parameters including DT_CALCRECT, and I see that the internal rc there gets the right size (these are the last line of the function):

...
CRect rc( rcText );
    rc.DeflateRect( &m_rcLabelTextMargins );
    dc.DrawText(
        LPCTSTR(strText),
        int(_tcslen(strText)),
        rc,
        dwDrawTextFlags
        );
    dc.SetTextColor( clrOldText );
    dc.SetBkMode( nOldBkMode );
    if( hFont != NULL )
        ::SelectObject( dc, hOldFont );
}

My problem is that this rc is local, so I cannot get this value... for now what I did was duplicate OnDrawLabelTextinto my derived, and made it return this rc of the actual size of the text.

Is is possible for next version that this function, which return void now, will return this size?

Many thanks,

Ron.

We guess you are discussing a simple text label control with left aligned text. In this case it’s possible even to design some new virtual methods in the CExtLabel class for measuring and painting additional content near the text. But labels can be center aligned, right aligned, single line, multi line and even bitmap based. So, approach should be definitively different. Please provide us with more details about your task so we can improve the CExtLabel class.

Dear Support,

The requirement I have is that there will be a line extending after the text all the way to the end of the label box (in the right theme of-course), like this:

I derived from CExtLabel, and added the line, but you are right, I did not add implementation for centered text etc.

I think that this is a nice feature - if you can add it to the coming version it’ll be handy for more library users.

Thanks,

Ron.

Dear Support,

I would like to add a rectangel on the dialog’s background.

What I did was override OnPaint of my CDialog derived class, and added simple rectangle drawing code.

I see the rectangle.

If I noe deriver my dialog class from CExtNCW<CExtResizableDialog>, the rectangle is not drawn. I see that my OnPaint is called, but no rectangle is shown.

Is there any sample of how to do it? is there any specific code I need to add?

Thanks,

Ron.

That’s not the reason.

Here it is when not derived from:CExtNCW<CExtResizableDialog>, the same with it, you see nothing on the left top corner:

I have modeless CExtResizableDialog windows that I destroy simply by deleteing the dialog object.  This worked fine with CDialog.

But with CExtResizableDialog, I sometimes get ON_UPDATE_COMMAND_UI messages during the destruction.  This causes all kinds of problems with parts of the member data freed.

Is there some was to turn these off before I destroy the window or some recommended sequence for destorying the dialog?

You should not destroy any CWnd-based C++ objects using the delete operator while these objects still subclass HWND window handle. You should not do this even if there are no crashes and assertions occur for particular CWnd-derived classes. At least, MFC prints warning messages into the Output window in Visual Studio when such objects are deleted. Such deletion is not suggested by MFC. Please invoke the CWnd::DestroyWindow() virtual method for destroying any kind of windows. Please override the CWnd::PostNcDestroy() virtual method and invoke the delete this; line of code at the end of it if your window should delete itself automatically. The CWnd::PostNcDestroy() virtual method is invoked when window handle is destroyed and when it was not created successfully inside invocation of the Create***() methods of any MFC and Prof-UIS classes. So, if you have the instance of some CWnd-based class which is allocated dynamically with the C++ new operator and if it’s Create() method returned negative result, then the PostNcDestroy() virtual method still allows you to self delete this object.

I’m using a modeless CExtResizableDialog and want to float it over other application (such as Excel) to drag and drop data.  I’m using this call:

      SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE);

This worked fine when I derived from CDialog but doesn’t work with CExtResizableDialog

We can create some test project which invokes the same line of code, but we would like not to guess how your real project really created dialog, which window styles are used by this dialog and so on. Could you please modify some simple Prof-UIS sample project like SDI, make it displaying dialog like your real project do and send this modified project to us.

I created different projects using variations of ProfUIS/non-ProfUIS dialogs and found that the problem isn’t related to your library.  Unfortunately I haven’t figured out what IS causing it.
