IFileDialogEvents::OnTypeChange method (shobjidl_core.h)
Called when the dialog is opened to notify the application of the initial chosen filetype.
Syntax
HRESULT OnTypeChange(
[in] IFileDialog *pfd
);
Parameters
[in] pfd
Type: IFileDialog*
A pointer to the interface that represents the dialog.
Return value
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
This method is called when the dialog is opened to notify the application of the initially chosen filetype. If the application has code in IFileDialogEvents that responds to type changes, it can respond to the type. For example, it could hide certain controls. The application controls the initial file type and could do its own checks, so this method is provided as a convenience.
