主要代码如下:

BOOL CmfctestDlg::ListCtrl_SetBackground(HWND hListCtrl,LPCTSTR pszImagePath,int width,int height)
{
    ListView_SetTextBkColor(hListCtrl,CLR_NONE);

	COLORREF clrBK=ListView_GetBkColor(hListCtrl);

	HICON hIcon=(HICON)::LoadImage(AfxGetResourceHandle(),pszImagePath,IMAGE_ICON,width,height,LR_DEFAULTSIZE);
	if(!hIcon)return FALSE;

	HBITMAP hBitmap=NULL;
	HWND  hwndDesktopDC=::GetDesktopWindow();
	HDC hDesktopDC=::GetDC(hwndDesktopDC);
	if(hDesktopDC)
	{
		HDC hdcMem=CreateCompatibleDC(hDesktopDC);
		if(hdcMem)
		{
			hBitmap=CreateCompatibleBitmap(hDesktopDC,width,height);
			if(hBitmap)
			{
               HBITMAP hOldBitmap=(HBITMAP)::SelectObject(hdcMem,hBitmap);
			   CRect rect(0,0,width,height);
			   ::SetBkColor(hdcMem,clrBK);
               ::ExtTextOut(hdcMem,0,0,ETO_OPAQUE,&rect,NULL,0,NULL);
			   ::DrawIconEx(hdcMem,0,0,hIcon,width,height,0,NULL,DI_NORMAL);
			
			   ::SelectObject(hdcMem,hOldBitmap);
			}
			::DeleteDC(hdcMem);
		}
		::ReleaseDC(hwndDesktopDC,hDesktopDC);

	}
	DestroyIcon(hIcon);

	if(hBitmap==NULL)
	{
		return FALSE;
	}

	LVBKIMAGE lvBK;
	lvBK.hbm=hBitmap;
	lvBK.xOffsetPercent=100;
	lvBK.yOffsetPercent=100;
	lvBK.ulFlags=LVBKIF_TYPE_WATERMARK;

	ListView_SetBkImage(hListCtrl,&lvBK);

	return TRUE;
