EditMask controls
When the AutoSkip property is enabled, the user's cursor will automatically skip to the next control in the tabbing order after entering all the characters allowed by the mask. If AutoSkip is not enabled, the cursor will not skip automatically to the next control.
To enable Auto Skip:
Select the AutoSkip check box on the Mask tab page of the EditMake control’s Properties view.
The AutoSkip property takes a boolean value. This example enables automatic skipping to the next control.
