Comments

The File Association dialog.

Use this dialog to control how the shell treats certain types of files. This lets you link your application to a certain file type, which causes the application to take ownership of that file type.

The parameters are used as input only and will not be updated by the dialog.

If the function was successful, then file formats will be associated or de-associated accordingly.

The same filter group string can be passed for both L_DlgOpen and L_DlgFilesAssociation because they have the same format.

Returns

SUCCESS_DLG_OK

The "OK" button was pressed, and the dialog exited successfully.

SUCCESS_DLG_CANCEL

The "Cancel" button was pressed, and the dialog exited successfully.

< 1

An error occurred. Refer to Return Codes.
