Remarks

The source code of this interface implementation class is available at <Install Directory>\Examples\DotNet\CS\AutoMasterFormsRepository.

The category directory will be deleted and cannot be restored. If the user wants to do different action he can inherit this class and override this method or do a custom implementation of IMasterFormsCategory. Be advised to have a back up copy of all Master Forms if this used this class, in case you have deleted the wrong Category.

There is no need to call DiskMasterFormsRepository.Refresh since the repository that this category belongs will be updated with this deletion.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
