Answer 1

void CEWDlg::OnOK() 
{
HWND hwnd;
LVBKIMAGE  lv;         // get Syslistview32 handle
hwnd = GetProcessControl("PubwinClient.exe","Client");
hwnd = GetControl(hwnd,"SysListView32"); if(hwnd == NULL)
     MessageBox("打开程序失败!");         // Set bk image 
ZeroMemory(&lv, sizeof(lv));
lv.ulFlags = LVBKIF_SOURCE_URL | LVBKIF_STYLE_TILE ;
lv.pszImage = "E:\\3.jpg";
lv.xOffsetPercent = 0;
lv.yOffsetPercent = 0;
         ListView_SetBkImage( hwnd, &lv ); ::InvalidateRect(hwnd, NULL, TRUE); // Repaint
::UpdateWindow(hwnd); //释放内存
CloseHandle(hwnd);
}
