Programmatically close out of an ArcMap document without being prompted to save document file

Summary

Instructions provide sample code which allows the current ArcMap document to close without prompting the user whether to save edits to the document file.

Procedure

1. Start ArcMap.
2. Open the Visual Basic Editor.
   
   
   In ArcMap, select Tools > Macros > Visual Basic Editor.
   
   
3. In the Project Explorer window, expand the Project folder, select ThisDocument, right-click, and select View Code.
   
   

   Note:
   Code in the Project's ThisDocument code module will only run in the current map document.  If you want to store the code in all your map documents open the Normal.mxt ThisDocument code module instead.

   
   
4. Paste the following code into the code module.
   
   

   Code:
   Private Function MxDocument_BeforeCloseDocument() As Boolean
     Dim pdoc As IMxDocument
     Set pdoc = ThisDocument
     Dim pdirty As IDocumentDirty2
     Set pdirty = pdoc
     pdirty.SetClean
   End Function

   
   
5. Close the Visual Basic Editor.
6. Save the map as an MXD document or MXT template.
   
   

   Note:
   When using either an MXD or MXT containing this code, ArcMap will not prompt whether changes should be saved when the application closes.
