You receive an application error when you call the Documents.Open automation method

A VBScript macro causes an application error in Msdev.exe when calling the Documents.Open method on a file that does not exist. This problem may occur, for example, if the file is managed by a source management system such as SourceSafe.

The file specified in the first Documents.Open parameter does not exist. The file may have been deleted or renamed on the local drive.

Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.This bug was corrected in Visual Studio 6.0 Service Pack 3.

The Documents.Open method takes three parameters:

• The path of the file to open.
• The editor to use for the file.
• A flag to open the file in read-only instead of read-write mode.

If the latter two parameters are unspecified, the method opens the file with the default editor in read-write mode.

If the file to be opened does not exist, VBScript throws a run-time exception error. The exception is normal and expected under this condition; however, Developer Studio does not handle it properly and faults internally.

Steps to reproduce the behavior

1. Create a new macro containing these lines:

   Sub DelAFile()
      Documents.Open "MyFile.cpp",,False
   End Sub

   In this example, the macro is named "DelAFile".
2. Create a new empty project.
3. Run the "DelAFile" macro repeatedly until an application error occurs.
