Remarks

This method is used to create form attributes to the Master Forms (unfilled form). The attributes that are generated using this method cannot be used as a Form attributes.

It returns null if the Object Managers that are set in the constructor are not suitable for this form, i.e. the Master Form does not have any features of the set Object Managers. Try using another Object Manager in order to detect the Master Form features.

Requirements

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