Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The duplicate or similar errors are the result of using the WordBasic Object to call WordBasic commands within a Visual Basic for Applications environment. In certain situations, if an error occurs, you will receive a Visual Basic for Applications error and a WordBasic error.

Furthermore, if the error number returned is greater than 1000, the WordBasic error cannot be trapped.

The following converted WordBasic macro example, when run in Visual Basic for Applications, will create duplicate errors if the file name you are attempting to open does not exist. The On Error statement will trap the Visual Basic for Applications error but it cannot trap the resulting WordBasic error. If you comment the On Error command line, two errors will occur when you attempt to open the non-existent file: "Microsoft Word error 1078" and "Microsoft Visual Basic run time error 1078."

   Sub MAIN()
      Dim MissingFile$
      On Error Resume Next
      MissingFile$ = "Macintosh HD:NoFile"
      WordBasic.FileOpen Name:=Chr(34) + MissingFile$ + Chr(34)
   End Sub
