From: Mohammad Omer on 7 Nov 2006 02:25 I tried those functions but water mark problem was not resolved. > [CASE-I] > LVBKIMAGE bkImage; > if( l_Ctrl.GetBkImage( &bkImage ) && (bkImage.ulFlags == > LVBKIF_SOURCE_NONE ) ) > { > bkImage.pszImage = TEXT( "E:\\ watermark.bmp" ); > bkImage.ulFlags = LVBKIF_SOURCE_URL | > LVBKIF_TYPE_WATERMARK; > bkImage.cchImageMax = sizeof( bkImage.hbm ); > bkImage.xOffsetPercent = 100; > bkImage.yOffsetPercent = 100; > if( l_Ctrl.SetBkImage( &bkImage ) ) > l_Ctrl.GetBkImage( &bkImage ); > } In CASE-I, if LVBKIF_TYPE_WATERMARK removes, it will be working fine in Win2K and WinXP. But this way anyone can change the image on the disk and it'll get changed in the application which is of course what I don't want. For this reason I tried to include that image in MFC Resource and code in CASE-II. > list view control name is l_Ctrl(List View Control) > [CASE-II] > LVBKIMAGE bkImage; > if( l_Ctrl.GetBkImage( &bkImage ) && (bkImage.ulFlags == > LVBKIF_SOURCE_NONE ) ) > { > HBITMAP hBitmap; > hBitmap = (HBITMAP)::LoadImage( AfxGetInstanceHandle( ), > MAKEINTRESOURCE( IDB_WATERMARK ), > IMAGE_BITMAP, > 0, 0, > LR_CREATEDIBSECTION | LR_LOADMAP3DCOLORS >); > bkImage.hbm = hBitmap; > bkImage.ulFlags = LVBKIF_SOURCE_HBITMAP; > bkImage.cchImageMax = sizeof( bkImage.hbm ); > bkImage.xOffsetPercent = 100; > bkImage.yOffsetPercent = 100; > if( ! l_Ctrl.SetBkImage( &bkImage ) ) > { > ::MessageBox( this->m_hWnd, TEXT("HBITMAP is Not Loaded"), > TEXT("Load Error"), MB_OK ); > } > } For some reasons this code works in WinXP but not in Win2K.

From: AliR (VC++ MVP) on 7 Nov 2006 12:33 Dude you are jumping from one branch to another. In Case I every thing is fine, but it will ONLY work on windows XP and above. LVBKIF_TYPE_WATERMARK is not supported by any operating system older than XP. I don't know why Case II is not working correctly. Looking at the docs for LVBKIMAGE struct it says that hbm is not being used. But you can clearly see MFC using it in Winctrl6.cpp in CListCtrl::SetBkImage method. So there is a goof somewhere. But there is a work-around: > > [CASE-II] > > LVBKIMAGE bkImage; > > if( l_Ctrl.GetBkImage( &bkImage ) && (bkImage.ulFlags == > > LVBKIF_SOURCE_NONE ) ) > > { TCHAR szBuffer[_MAX_PATH]; VERIFY(::GetModuleFileName(AfxGetInstanceHandle(), szBuffer, _MAX_PATH)); CString sPath; sPath.Format(_T("res://%s/#2/#%ld"),szBuffer,IDB_WATERMARK); bkImage.pszImage = sPath.GetBuffer(); > > bkImage.ulFlags = LVBKIF_SOURCE_HBITMAP; > > bkImage.cchImageMax = sizeof( bkImage.hbm ); > > bkImage.xOffsetPercent = 100; > > bkImage.yOffsetPercent = 100; > > if( ! l_Ctrl.SetBkImage( &bkImage ) ) > > { //error > > } spPath.ReleaseBuffer(); > > } Again with all of these in order to see the image while there are items in the list control you will need to set the bk color of the text to none. So make sure you are calling l_Ctrl.SetBkColor(CLR_NONE); l_Ctrl.SetTextBkColor(CLR_NONE); AliR.

From: Mohammad Omer on 8 Nov 2006 02:29 Thanks, it works with LVBKIF_SOURCE_URL flag. > CString sPath; > sPath.Format(_T("res://%s/#2/#%ld"),szBuffer,IDB_WATERMARK); Few of things are not understand in "sPath" value, what is representing in it? The "sPath" contains "res://e:\vc\TestWaterMark\debug\TestWaterMark.exe/#2/#198". Is "res://" mean protocol for loading thing from resources? Is "e:\vc\TestWaterMark\debug\TestWaterMark.exe" will be the absolute path of exe or dll path or only exe path? What is "#2" that means? And "#198" is my resource Id.
