Example

The follwing example will make even numbered bitmap items in the

animation wait for user input, and then reads the new state for each

item in the bitmap list.

L_INT LAnimationWindow_WaitForUserInputExample(HWND hWndParent)
{
   L_INT nRet;
   L_UINT i;
   LBase::LoadLibraries(LT_ALL_LEADLIB); 
 //make sure all libraries are loaded
   LAnimationWindow MyAnimation;
   WRPUNLOCKSUPPORT();
   MyAnimation.SetFileName(TEXT("%UserProfile%\\My Documents\\LEADTOOLS Images\\eye.gif"));
   nRet = MyAnimation.Load();
   if (nRet==SUCCESS)
   {
      MyAnimation.CreateWnd(hWndParent,0, WS_VISIBLE|WS_CHILD|WS_BORDER,0,0,300,300);
      //let the even items wait for user input
      for (i=0; i<MyAnimation.GetCount(); i++)
      {
         if (i%2)
         {
            nRet = MyAnimation.WaitForUserInput(FALSE,i);
            if(nRet != SUCCESS)
               return nRet;
         }
         else
         {
            nRet = MyAnimation.WaitForUserInput(TRUE,i);
            if(nRet != SUCCESS)
               return nRet;
         }
      }
      for (i=0; i<MyAnimation.GetCount(); i++)
      {
         L_TCHAR szStr[255];
         //get current wait state
         wsprintf(szStr,TEXT("Bitmap[%d] Wait For User Input?: %s"),i, (MyAnimation.IsWaitingForUserInput(i)?TEXT("YES"):TEXT("NO")));
         MessageBox(hWndParent, szStr,TEXT("Example"), MB_OK | MB_ICONINFORMATION); 
      }
   }
   else
      return nRet;
   return SUCCESS;
