owner
Handle to the owner window.
flags
Flags that determine the options dialog. For possible values refer to ScreenCaptureDialogFlags.
captureObjectOptions
A ScreenCaptureObjectOptions structure to be filled with the data from the dialog.
useDefault
If true, the dialog will start with default values. Otherwise the dialog will use the values specified by the captureObjectOptions structure. These values must be valid values or the dialog will return an error code.
helpCallback
A delegate method that will handle the event.
Returns the value of the dialog box that specifies the identifiers.
