WD: WordBasic Err=150 with Duplicate UserDialog Definitions


The information in this article applies to:

  • Microsoft Word for Windows, versions 6.0, 6.0a, 6.0c
  • Microsoft Word for Windows 95, version 7.0
  • Microsoft Word for the Macintosh, versions 6.0, 6.0.1


The following WordBasic error occurs in Microsoft Word if your custom dialog box definition includes two instructions that specify the same identifier argument:

WordBasic Err=150
Dialog control identifier is already defined.

For example, the following macro causes this error message because both CheckBox dialog box instructions are identical:

   Sub MAIN
   Begin Dialog UserDialog 151, 84
      OKButton 33, 48, 88, 21
      CheckBox 25, 16, 111, 16, "Check Box", .CheckBox1
      CheckBox 25, 16, 111, 16, "Check Box", .CheckBox1
   End Dialog
   Dim Dlg As UserDialog
   Dialog Dlg
   End Sub 

By contrast, this macro does not cause an error when you run it in Word version 2.x for Windows.

Identifiers for controls in a custom dialog box must be unique.


To work around this problem, if you run a Word 2.x macro in Word 6.0 or later that contains duplicate dialog box identifiers, you must edit the macro and remove or modify one of the identifiers.


Microsoft has confirmed this to be a problem in Microsoft Word 2.x, which should also only have allowed unique identifiers. This problem was corrected in later versions of Microsoft Word.
