Q276560: BUG: CompilerError with Left Function When Devshl.dll Referenced

Article: Q276560
Product(s): Microsoft Visual Basic for Windows
Version(s): 6.0
Operating System(s):

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual Basic Enterprise Edition for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you use the Left string function in Visual Basic and your project contains
a reference to Microsoft Visual C++ Shared Objects (Devshl.dll), you may receive
the following compiler error message:

  Wrong number of arguments or invalid property assignment

This does not occur when you use a form module, but may occur when you use a
standard or class module.

CAUSE
=====

The compiler seems to resolve the Left function in Devshl.dll instead of in the
VBA library. Because Left is a property of the Application and Window objects in
Devshl.dll, you receive an error when you call Left as a function.

RESOLUTION
==========

Fully qualify the call to the Left function, as in the following example:

  Sub foot()

      Dim s As String
      s = "skdfhshfsdlkf"
      s = VBA.Left(s, 3) 'Fully qualified
      
  End Sub

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

MORE INFORMATION
================

Steps to Reproduce Problem
--------------------------

1. In Visual Basic version 6.0, create a new Standard EXE project. Form1 is
  created by default.

2. Add a class module to the project.

3. Add the following code to the class module:

  Sub foot()
      Dim s As String
      s = "skdfhshfsdlkf"
      s = Left(s, 3)
  End Sub

4. Set a reference to Visual C++ Shared Objects (Devshl.dll).

5. Press CTRL+F5 to start the application with full compile. You receive the
  error message listed in the "Symptoms" section.
