The IAMVfwCaptureDialogs interface is implemented on the VFW Capture filter. This interface enables an application to display one of the three dialog boxes (Source, Format, or Display) provided by Microsoft® Video for Windows® capture drivers. Any application that enables the user to change settings in a Video for Windows capture driver-supplied dialog box should use this interface.
In addition to the methods inherited from IUnknown, the IAMVfwCaptureDialogs interface exposes the following methods.
| Method | Description |
| HasDialog | Determines if the specified dialog box exists in the driver. |
| ShowDialog | Displays the specified dialog box. |
| SendDriverMessage | Sends a driver-specific message. |
