How do I insert a row into a filtered tree grid whilst honouring if/where the new row should be inserted, other than to:

1. Save filters

2. Clear filters

3. Insert item

4. restore filters

It crashes calling ItemInsert(ItemGetRoot(), nIndex) when nIndex is greater than the number of visible rows, so I assumed nIndex was a visible index.  Any sugestions?

Could you show the call stack listing at the assertion time?

Thanks for that.

I manage my own sorting and want to insert an item between rows that may be hidden, can I do this without saving/clearing/restoring the filter?

I would be nice if ItemInsert() could take a HTREEITEM instead of a visible row index & insert into the full grid whilst filters are applied - the new item only being displayed if it meets the filters criteria.

 

 

The CExtTreeGridWnd::ItemInsert() method does what you need. The nIdxInsertBefore parameter is an index in the array of all child nodes including the hidden ones. The CExtTreeGridWnd::ItemGetSiblingIndexOf() method allows you to convert a tree item handle into its sibling index.

Dear Support,

I have upgrade the Prof-uis Library to the current version.

I would like to use your ResizablePropertySheet dialog and i love it. However, i found that the sample of ResizablePropertySheet you have provided is too much flicker. Especially when i resize the dialog box. The other think is when i click the mouse over the dialog is also create flicker at the first time. Do you have any suggestion as to how eliminate the flickering. I do not mind if the property dialog box stay on fix size. Please give me your advice.

I am looking forward to hearing your respond. Thank you.

Yes, it’s present in 2.90. We fixed it in 2.91 and we can provide you with the source code update.

We are experiencing this as well and are on 2.9.0

I have a complex control inside a CExtResizableDialog.  When this control has the focus, I use the tab key to navigate inside of it.  This works fine inside a CDialog.  But inside CExtResizableDialog, I’m not getting any OnKey or OnChar events for VK_TAB.  Instead the dialog is moving the focus to another control in the dialog.

The control returns DLGC_WANT_ALL_KEYS for OnGetDlgCode()

Is there any way to  override this?

Can you direct me to some place I could set a breakpoint and see if I can determine what’s happening?

The CExtResizableDialog::PreTranslateMessage() method handles VK_TAB key pressing and invokes the CExtResizableDialog::stat_GetNextItemZ() method for searching for the next dialog item to focus.

The CExtResizableDialog class uses a VK_TAB key processing code based on thread wide hooks. It is written from scratch. We tried to make this algorithm working exactly like the default dialog’s algorithm. It sends WM_GETDLGCODE messages to dialog controls and analyzes WS_TABSTOP, DS_CONTROL, WS_VISIBLE, WS_DISABLED and WS_EX_CONTROLPARENT styles (see the CExtResizableDialog::stat_GetNextItemZ() method’s source code). We carefully tested this algorithm and it worked like the standard dialog’s algorithm. We had to code it because the standard algorithm does not work with owner-draw skinned button controls like CExtButton, CExtCheckBox, CExtRadioButton and CExtHyperLinkButton. We had several issue reports about this algorithm more than year ago just when it appeared in Prof-UIS. All of them were fixed and nobody reported any new issues. So, it would be very interesting to re-check this algorithm and fix it if needed. Please provide us with more details or, even better, with some test project reproducing this issue.

Dear Support,

If I have 3 control-bars floating one next to each other (not touching each other, with some space between them) and I resize them, each one I resize gets a focus caption (in silver theme, an orange title).

It seems that you do not refresh their title unless they overlap or something like this.

Thanks,

Ron.

Hi,

We upgraded to 2.90 from 2.87, and now, when we have a control-bar and we try to resize it by dragging its borders there is a delay of about a second between the start of the dragging until the dragging actualy begins.

* This does not happen if the control-bar is the focused control-bar. It seems that you need to repaint it or something like this prior to moving it, and it causes a notable delay.

* This was all tested in release version.

Please fix.

Thanks,

Ron.

We tried simple CExtControlBar control bars and dynamic CExtDynamicControlBar control bars on Windows XP SP3 and Office 2007 themes. The 200...300 millisecond delay can be reproduced only if:

1) Computer is not new and enough slow. The LG M1 Pro notebook for instance.

2) Debug application version is used.

3) Application creates many control bars and all of them are visible and docked inside the main frame and not auto-hidden. We used MDI_DynamicBars sample application.

The 200...300 millisecond delay in this case is the frame layout recalculation after un-docking the control bar. We can programmatically increase this delay using heavy timer handler code or heavy idle time processing code.

Dear Support,

1) The computer is OK, but not new.

2) I am only testing in release mode.

3) How much is any? 10? 20? 30? 100? can you give me a number?

My main input is that if prior to resizing, the control-bar had focus there is no delay, but if it does not have focus there is a delay - how can this be? why does it matter?

We use some timers in our application, as it needs to update the UI, but why does it generates delays in Prof-UIS’s focus changing algorithms?

30..50 bars is enough. The focus affects the OnCmdMsg() and PreTranslateMessage() routing. Some of these method implementations can be slower than other.

Which sample app should we try to reproduce this? Which UI theme should be selected? Which Windows version?

Hi,

Please see the 2 pictures below - these are two separate instances where tab control is used in 2010 black theme.

The first one is just two docking bars filled with a grid control that they are tabbed together. You can see that the tab control have some dark-grey space beteween the grids and the tabs - this makes the tabs to look our of place.

The second one is a CExtTabPageContainerWnd with two dialogs in it. Again, it seems a little off - there is no separation  between the tab and contained dialogs, which makes it looks like the tabs are in mid-air.

Please fix.

Thanks,

Ron.

Replied.

We haven’t received it. Sorry. Please try to send it from other e-mail address or to our second email account profuis at gmail com.

Fixed. Please send us e-mail so we will provide you with the source code update download.

The print preview feature in the project PropertyGrid, colors the property names in black. Is there a setup one could use to change that and make the info visible?

I sent you also an email with a snapshot showing this issue ( I used VS 2008 on Windows XP Ultimate with the latest patches).

 

Thank you,

Bogdan

It worked. Thank you!

This is the call-stack when it crashes with the dialog enlarged so no scrolling is needed to cause a crash:

Wrong thread... sorry.

Dear Support,

We found a bug after calling ItemHide in 2.87. We are also sending you an application to reproduce the crash.

The crash happens in the following squence:

1) Adding a few nodes with leafs, expanding the node (ItemExpand)

2) Hiding one node from the middle of the tree, and adding leafs to the last node

If the whole tree is visible, the crash will happen when adding the leaf to the last node when OnSwUpdateScrollBars is called.

If the last node is not visible, the crash will happen as soon as you scroll to the last node.

Please let us know that you received the application via mail.

Thanks,

Ron.

Thank you for providing us with the test project. It crashes with Prof-UIS 2.87. It works with Prof-UIS 2.90. So, the fix is Prof-UIS 2.90.

Dear Support,

This is the crash when the dialog is enlarged before pressing the two buttons, and causing the crash right at the button 2 clicking:

Dear Support,

It crashes in 2.90 as well - please check with the official version you released. Below is the call stack with the sample application I sent you when crashing it 2.90. Please fix this - we need this feature.

Thanks,

Dear Support Team,

a stupid question concerning the TVN_ENDLABELEDIT notify message. Why do you send the "old text" with this message and not the edited text?

in conformity with msdn:

Pointer to an structure. The item member of this structure is a structure whose hItem, lParam, and pszText members contain valid information about the item that was edited. If label editing was canceled, the pszText member of the TVITEM structure is NULL; otherwise, pszText is the address of the edited text.

void CExtTreeCtrl::OnInplaceControlComplete(

      ...

      _data.hdr.code = TVN_ENDLABELEDIT;
        _data.item.mask = TVIF_CHILDREN|TVIF_HANDLE|TVIF_PARAM|TVIF_STATE;
        _data.item.hItem = hti;
        GetItem( &_data.item );
        strItemText = GetItemText( hti );
        bool bModeNotNULL = true;
        if( strItemText == LPCTSTR(strEditedText) )
        {
            bModeNotNULL = false;
            _data.item.cchTextMax = 0;
            _data.item.pszText = 0;
        }
        else
        {
            _data.item.cchTextMax = INT(strItemText.GetLength());
            _data.item.pszText = strItemText.IsEmpty() ? _T("") : LPTSTR(LPCTSTR(strItemText));
            _data.item.mask |= TVIF_TEXT;
        }

You send the strItemText (old text) not the strEditedText (edited text).

Hello,
I have a Dialog (CExtResizableDialog) wich is contained in a CExtControlBar. The Dialog contains a vertical slider. If I add an Anchor like the following to it:

AddAnchor(IDC_SLIDER_HEIGHTANGLE, CPoint(0,0), CPoint(0, 100));

The application crashes with an assertion.

regards
Sebastian

Having deleted all items from the grid using ItemRemove() for each item, the following code reports a row is focused, even though there are no rows in the grid.

 

CPoint pt = FocusGet();

if(pt.x != -1 && pt.y != -1)

         return true;

return false;

 

Any ideas?

 

 

I’m currently using the following code to update the UI state.  How can I do this outside of ::OnCmdMsg()

BOOL CPlantingLibrariesDlg::OnCmdMsg(UINT nID, INT nCode,

void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo) // update UI

 

{

 

{

case ID_LIBRARY_DELETE:

 

pCmdUI->Enable(m_wndLibraryList.SelectionIsEmpty() ? FALSE : TRUE);

 

 

}

break;} 

if(nCode == CN_UPDATE_COMMAND_UI)switch(nID)

{

CCmdUI * pCmdUI = (CCmdUI*)pExtra;

 

Here is how to make your toolbar to perform the command updating requests for all the buttons through its parent dialog window:

CExtToolControlBar * pToolBar = . . . 
CExtResizableDialog * pDialog = . . .
            pToolBar->OnUpdateCmdUI( (CFrameWnd*) pDialog, TRUE );

I’m handling MFC command updating though CExtResizableDialog::OnCmdMsg().

Having deleted all items from a list I need to update the toolbar to disable a button.

How do I force OnCmdMsg() to update?

 

Hello.

Do not you understand the meaning of the question?

http://www.prof-uis.com/prof-uis/tech-support/support-forum/a-frame-freezes-cextcontrolbar-67719.asp

Hello.

I set variable declaration of CheckBox in CExtCheckBox.

The setting of the standard button does not work.

I declare CheckBox in CButton

When I assign a focus to CheckBox and push Return Key, DefPushButton is pushed.

However,

I declare CheckBox in CExtCheckBox

Even if I assign a focus to CheckBox and push Return Key, DefPushButton does not become effective.

Because the setting of the standard button does not work, I cannot close a dialog.

 Even if it is declared in CExtCheckBox,

Please teach me the method that DefPushButton becomes effective

Or please revise it

Please answer immediately.

 

 

 

Hi,

I would like to get some buttons into the title bar of the MDI child views of my MDI application. I thought, that perhaps I can use the ribbon bar to do this.

Is it possible to imlement a ribbon bar to a MDI CHild View?

Thanks.

Regards,
Andreas

Hi,

We have a dialog box, based on a resource, where the title contains "&", eg "This & That".  But in the dialog box title it appears as "This && That", doubling the "&".  How should I stop that?

Thanks,

Rob.

Thanks, but I’m afraid with this change I now get an assertion when I start up my app.  Here’s the Prof-UIS part of the call-stack:

	 cadwind.exe!CExtCustomizeSite::CCmdMenuInfo::Initialize(CWnd * pWndTop=0x087f47e8, unsigned int nResourceID=10005, bool bDefaultMenu=false, bool bPopupMenu=false)  Line 2164 + 0x1c bytes    C++
	 cadwind.exe!CExtCustomizeSite::MenuInfoAdd(CWnd * pWndTop=0x087f47e8, const char * strName=0x053f368c, unsigned int nResourceID=10005, bool bDefaultMenu=false, bool bPopupMenu=false, CRuntimeClass * pRtcFrame=0x02adeaf4, CRuntimeClass * pRtcView=0x00000000, CRuntimeClass * pRtcDoc=0x00000000)  Line 5589 + 0x18 bytes    C++

I took it out again, and no more assertion.  Don’t know what’s going on there.

Thanks,

Rob.

Any answer to this?  I can’t see why your change should cause the above problem, but after recompiling everything, it seems to.  For now, I can’t use your patch.

Thanks,

Rob.

We suspect you may have applied the patch incorrectly. Here is what we saw:

http://www.prof-uis.com/download/forums/tmp/ThisAndThat.png

You can drop us an e-mail so we will provide you with the Prof-UIS 2.91 download.

Hi again,

I decided to download the latest beta, 2.9.1 2010-09-12.  But now it hits assertions in a different place.  After stepping through these it does indeed seem to work and not have the previous problem I encountered.

The top of the new stack is as follows:

>    cadwind.exe!CExtPaintManagerOffice2010_R2_Black::CExtPaintManagerOffice2010_R2_Black()  Line 36613 + 0x3d bytes    C++
     cadwind.exe!CExtPaintManagerOffice2010_R2_Black::CreateObject()  Line 237 + 0x72 bytes    C++
     mfc80d.dll!CRuntimeClass::CreateObject()  + 0xba bytes    
     cadwind.exe!CExtPaintManager::CExtPaintManagerAutoPtr::InstallPaintManager(CRuntimeClass * pRtcPaintManager=0x065d8d58)  Line 1144 + 0x8 bytes    C++

The code in question is new since my previous 2.9.1 beta.  Here’s the new chunk:

    VERIFY(
        m_arrBmpTabArea[__ETSOI_TOP].LoadBMP_Resource(
            MAKEINTRESOURCE( IDB_EXT_2010_TAB_AREA_BK_BLACK )
            )
        );
    VERIFY( m_arrBmpTabArea[__ETSOI_TOP].Make32() );
CSize _sizeTabArea = m_arrBmpTabArea[__ETSOI_TOP].GetSize();
    m_arrBmpTabArea[__ETSOI_TOP].PreMultipliedRGBChannelsSet( true );
    VERIFY(
        m_arrBmpTabArea[__ETSOI_BOTTOM].CreateRotated9xStack(
            m_arrBmpTabArea[__ETSOI_TOP],
            180,
            1,
            _sizeTabArea.cx,
            _sizeTabArea.cy,
            false,
            false
            )
        );
    VERIFY(
        m_arrBmpTabArea[__ETSOI_LEFT].CreateRotated9xStack(
            m_arrBmpTabArea[__ETSOI_TOP],
            270,
            1,
            _sizeTabArea.cx,
            _sizeTabArea.cy,
            false,
            false
            )
        );
    VERIFY(
        m_arrBmpTabArea[__ETSOI_RIGHT].CreateRotated9xStack(
            m_arrBmpTabArea[__ETSOI_TOP],
            90,
            1,
            _sizeTabArea.cx,
            _sizeTabArea.cy,
            false,
            false
            )
        );

Every VERIFY above fails.  Is this a known issue?

Further to the above comment, I now see that the chunk of code is repeated seven times throughout that file, with only the IDB_EXT_2010_TAB_AREA_BK_BLACK at the start changed.  Some were there before (the ones with ...2007... IDs) and seem to be fine.  The new ones, using the ...2010... IDs cause assertions though.

Thanks,

Rob.

There are two common cases when Prof-UIS resources cannot be loaded:

1) The Prof-UIS is linked with your app statically and Prof-UIS resources are not available. The .rc2 file of your project should contain the following lines:

#if ( !(defined _AFXDLL && !defined __STATPROFUIS_WITH_DLLMFC__) )
            #include <Resources/Resource.rc>
#endif

1) The 28000..32000 range of resource identifiers is used by Prof-UIS. The resource.h file of your project should not define identifiers in this range.

Neither of those things seem to be the problem.  It works fine if I just comment out the chunks of code I mentioned above, so all other ProfUIS resources seem to be fine.

We are linking statically, but our .rc2 files have had the code you suggest since the start.

I’ll try another nightly build sometime.  Otherwise, not sure what’s going on here.

Please update the source code for the following method:

I’m using the following the hide a column

ExtentSet(0);

ExtentSet(0, 1);

and the following to show a column:

ExtentSet(1, -1);

ExtentSet(1024, 1);

pHdr->ExtentSet(g_PaintManager->UiScalingDo(100, CExtPaintManager::__EUIST_X));

 

The problem is the column is shown but re-sizing no longer works.

 

 

 

Is it possible to show some text in CExtProgressWnd like in CExtGridCellPrgress ? There is no documentation about CExtProgressWnd in the help.
Thank you.

I have a modeless dialog with a slider control and 3 radio buttons.  If I create it then close it (calling DestroyWindow()), I get a heap corruption error.

If I change it to use CDialog and standard windows controls, the problem goes away.

I’m on version 2.90.  Are there any known bugs that might be causing this?

Could you send us a simple test project with a simple dialog and its radio buttons to the support mail box at this web site?

My Struct Member Alignment is "Default".  What should it be?

Did you change the structure member alignment compiler option of your project or Prof-UIS library project?
