IProgressDialog::SetAnimation method (shlobj_core.h)

[This method is not supported in Windows Vista or later versions.]

Specifies an Audio-Video Interleaved (AVI) clip that runs in the dialog box.

Syntax

HRESULT SetAnimation(
  [in, optional] HINSTANCE hInstAnimation,
                 UINT      idAnimation
);

Parameters

[in, optional] hInstAnimation

Type: HINSTANCE

An instance handle to the module from which the AVI resource should be loaded.

idAnimation

Type: UINT

An AVI resource identifier. To create this value, use the MAKEINTRESOURCE macro. The control loads the AVI resource from the module specified by hInstAnimation.

Return value

Type: HRESULT

Returns S_OK if successful, or an error value otherwise. In Windows Vista and later versions, always returns S_OK.

Remarks

IProgressDialog::SetAnimation cannot be called before the progress dialog is visible. Until it is displayed, the progress dialog does not have a valid HWND. The existence of that HWND can be used to determine whether IProgressDialog::SetAnimation can be called.

This method takes the instance handle specified by hInstAnimation and uses an animation control to open and run a silent AVI clip. There are several restrictions as to what types of AVI clips can be used, including the following:

• Clips cannot include sound.
• The size of the AVI clip cannot exceed 272 by 60 pixels. Smaller rectangles can be used, but they might not be properly centered.
• AVI clips must either be uncompressed or compressed with run-length (BI_RLE8) encoding. If you attempt to use an unsupported compression type, no animation is displayed.
