From: Neo on 3 Nov 2006 11:59 I am developing SDI application in vc using vs2k5. my *view* class (CTestView) inherited from CListView. I want to place background Image in list view. I wrote following code in "CTestView::OnInitialUpdate()" function, list view control name is l_Ctrl(List View Control), and working fine with Tile Style in both operating system Win2K and WinXP. if( l_Ctrl.GetBkImage( &bkImage ) && (bkImage.ulFlags == LVBKIF_SOURCE_NONE ) ) { l_Ctrl.SetBkImage( TEXT( "E:\\watermark.bmp" ), TRUE ); } I want to show image as Water Mark in view area, following code (uses SetBkImage function by passing LVBKIMAGE structure) which is working fine (in case of loading image from file) only in Win2K but its not working in WinXP. [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 ); } the following code is not working in nieither Win2K nor WinXP, IDB_WATERMARK is Bitmap Resource which has been added in Project. But the following code works fine in WinXP only if "bkImage.ulFlags = LVBKIF_SOURCE_HBITMAP". [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 | LVBKIF_TYPE_WATERMARK; 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 ); } } please tell me mistakes in my code for displaying image as water mark in List View, and tell me corrections for making it work on Win2k and WinXP. Please explain, why Case-I works in Win2k but not in WinXP? And why case-II with changes works in WinXP but not in Win2k? regards, -aims

From: AliR (VC++ MVP) on 6 Nov 2006 16:27 Is it still returning 0 or is it returning 1 and you can't see the image? AliR.

Make sure you have the calls to set the bkcolor and textbkcolor to transparent m_cList.SetBkColor(CLR_NONE); m_cList.SetTextBkColor(CLR_NONE); m_cList.SetBkImage("c:\\gto.bmp",TRUE); AliR.
