The following function creates an animation control in a dialog box. The
animation control is positioned below the specified control, and the dimensions of
the animation control are based on the dimensions of a frame in the AVI clip.
// CreateAnimationCtrl - creates an animation control, positions it
// below the specified control in a dialog box, and opens the AVI
// clip for the animation control.
// Returns the handle to the animation control.
// hwndDlg - handle to the dialog box
// nIDCtl - identifier of the control below which the animation control
// is to be positioned
//
// Constants
// IDC_ANIMATE - identifier of the animation control
// CX_FRAME, CY_FRAME - width and height of the frames
// in the AVI clip
HWND CreateAnimationCtrl(HWND hwndDlg, int nIDCtl)
{
HWND hwndAnim = NULL;
RECT rc;
POINT pt;
// Create the animation control.
hwndAnim = Animate_Create(hwndDlg, IDC_ANIMATE,
WS_BORDER | WS_CHILD, g_hinst);
// Get the screen coordinates of the specified control button.
GetWindowRect(GetDlgItem(hwndDlg, nIDCtl), &rc);
// Convert the coordinates of the lower-left corner to
// client coordinates.
pt.x = rc.left;
pt.y = rc.bottom;
ScreenToClient(hwndDlg, &pt);
// Position the animation control below the Stop button.
SetWindowPos(hwndAnim, 0, pt.x, pt.y + 20,
CX_FRAME, CY_FRAME,
SWP_NOZORDER | SWP_DRAWFRAME);
// Open the AVI clip, and show the animation control.
Animate_Open(hwndAnim, "SEARCH");
ShowWindow(hwndAnim, SW_SHOW);
return hwndAnim;
