This method throws an ArgumentNullException if:

  • Factory GUID value passed in factoryType is nulla null reference (Nothing in Visual Basic).

ArgumentException

Remarks

This constructor is useful if you do not have access to the editor factory because it is implemented elsewhere.

Examples

The following C# code applies the RegisterEditorExtension attribute to a VSPackage named BasicEditor.

using Microsoft.VisualStudio.Shell;
using MSVSIP = Microsoft.VisualStudio.Shell;
[MSVSIP.RegisterEditorExtension(typeof(EditorFactory), ".myext", 32, "{A2FE74E1-B743-11d0-AE1A-00A0C90FFFC3}", "..\\..\\Templates", 106)]
