Just open the ProfUIS_900_x64.sln with Microsoft Visual studio 2008

Build the project  Prof-UIs Controls with configuration "Static MBCS Release with MFC Dll" and Platform x64

Start the program on Windows Server 2003, x64 edition and click ListView, Notice the list column headers are not displayed correctly.

Resize the main window and then program crashes.

The debug build works fine. Only the release build crashes. Tested the Prof-Uis version 2.85 and 2.88, both have the same problem.

It seems to crash somewhere in CExtHeaderCtrl.

Please let know if this is a bug and any solutions. Thanks

We reproduced this issue. Thank you. To fix it, please update the source code for the following method:

void CExtHeaderCtrl::OnPaint() 
            ASSERT_VALID( this );
CRect rcClient;
            GetClientRect( &rcClient );
CPaintDC dcPaint( this );
CExtMemoryDC dc( &dcPaint, &rcClient );
            OnEraseHeaderBackground( dc, rcClient );
INT nColNo, nColCount = INT(GetItemCount());
            for( nColNo = 0; nColNo < nColCount; nColNo++ )
                        CRect _rcItemEntire;
                        if( ! GetItemRect( nColNo, &_rcItemEntire ) )
                        if( ! dc.RectVisible( &_rcItemEntire ) )
                        HD_ITEM _item;
                        ::memset( &_item, 0, sizeof(HD_ITEM) );
                        _item.mask = UINT(-1) & (~(__EXT_MFC_HDI_FILTER));
                        TCHAR strText[ 1024 ];
                        ::memset( strText, 0, sizeof(strText) );
                        _item.cchTextMax = sizeof( strText ) / sizeof( strText[0] - 1 );
                        _item.pszText = strText;
                        GetItem( nColNo, &_item );
                        OnPaintHeaderItem( dc, _item, nColNo, _rcItemEntire );
Please also add the following line of code somewhere before the method mentioned above:
#define __EXT_MFC_HDI_FILTER              0x0100

Thanks! The problem is fixed

The CExtHeaderCtrl themed header control in Prof-UIS 2.88 and older versions can really cause crashes on particular systems, especially if the header text is quite short (less than 5 characters). This is fixed in v.2.89.

Prof-UIS 2.89 has the exactly same problem!

Please test it following the above procedure and let me know if you can fix it.
