Animated Progress bar not Playing avi file....

[dverma05]

Hi All,

I have a Modeless dialog which is showing a animated progress bar by playing an avi file(soundless). Actually whenever i am exporting any file i have to display this progress bar as a part of modeless dialog. The problem which i am facing is, just after poping this dialog the avi file is not playing and when i am draging the dialog by a bit, it start playing.
I tried to get rid of this problem by moving dialog programatticly. I am doing all my programming in win32.
Here is the part of the code where i am creating the animation.

BOOL CALLBACK CProgressDlg::ProgressDialogProc( HWND hdlg, UINT message, WPARAM wParam, LPARAM lParam )
{
	
	CProgressDlg  *pDlg = NULL;
	pDlg = (CProgressDlg*)GetWindowLongPtr(hdlg, GWLP_USERDATA);
    switch (message) 
    {
	case WM_INITDIALOG:
		{
			pDlg = (CProgressDlg*)lParam;
			SetWindowLongPtr(hdlg, GWLP_USERDATA, (LONG_PTR)pDlg);
			pDlg->m_hWnd = hdlg;
			CenterWindow(hdlg, NULL);
			SetWindowText(hdlg, pDlg->m_msg);

			HWND hWndAnimate = GetDlgItem(hdlg, IDC_ANIMATE);
			HWND hWndMsg = GetDlgItem(hdlg, IDC_STATUS_TEXT1);
			HWND hProgress = GetDlgItem(hdlg, IDC_PROGRESS);
			HWND WndProgressAnimate = GetDlgItem(hdlg, IDC_PROGRESS_ANIMATE);

			Animate_Open(hWndAnimate, MAKEINTRESOURCE(IDR_AVI1)); 
			DoAnimation(hWndAnimate, PLAYIT);
			SetDlgItemText(hdlg, IDC_STATUS_TEXT1, pDlg->m_msg);
			HWND hOk = GetDlgItem(hdlg, IDC_OK);
			ShowWindow(hOk, SW_HIDE);
			Animate_Open(WndProgressAnimate, MAKEINTRESOURCE(IDR_AVI3));
			
			DoAnimation(WndProgressAnimate, PLAYIT);		

			if (pDlg->m_bProgress)
			{
				if(!(pDlg->m_bIsHess))
				{
					ShowWindow(hProgress, SW_SHOW);
					ShowWindow(WndProgressAnimate, SW_HIDE);
				}
				else
				{
					ShowWindow(WndProgressAnimate, SW_SHOW);
					ShowWindow(hProgress, SW_HIDE);
				}
			}
			else
			{
				ShowWindow(hProgress, SW_HIDE);
				ShowWindow(WndProgressAnimate, SW_HIDE);
			}
		}
		break;
	case WM_COMMAND:
       switch (LOWORD(wParam))
		{ 
        case IDC_OK: 
			PostMessage(hdlg,WM_QUIT,0,0);
			break;
		} 
		break;
    } 
    return FALSE; 
}

and DoAnimation is as follows:

void DoAnimation(HWND hwndAnim, int nAction)
{ 
    switch (nAction) { 
        case PLAYIT: 
         // Play the clip continuously starting with the 
         // first frame. 
            Animate_Play(hwndAnim, 0, -1, -1); 
            break; 

        case STOPIT: 
            Animate_Stop(hwndAnim); 
            break; 

        case CLOSEIT: 
            Animate_Close(hwndAnim); 
            break; 

        default: 
            break; 

    } 

    return; 
}

I have attached the avi file. Quick responce are most welcome....
