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

- Microsoft Windows CE Toolkit for Visual Basic 6.0 
- Microsoft eMbedded Visual Basic, version 3.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you explicitly refer to variables in a module, such as Module1.Variable1,
the following error occurs:

  An error was encountered while running this program.

RESOLUTION
==========

When you compile Windows CE projects in Visual Basic all module information is
concatenated together and module names are not retained. Thus, making the module
variables public and referring to them elsewhere in the project without the
module name avoids the error. Ensure that the names of those variables do not
conflict with any public variables declared in any form or code module.

STATUS
======

This behavior is by design.

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

Steps to Reproduce Behavior
---------------------------

1. Create a new Windows CE project in either Visual Basic or eMbedded Visual
  Basic. Form1 is created by default.

2. Add a Standard Module to the project, named Module1 by default.

3. Add the following code to Module1:

        Option Explicit
        Public VariableInModule

4. Add the following code to the code module of Form1:

        Option Explicit

        Private Sub Form_Click()
           'This does not work:
           Module1.VariableInModule = "Test"
        End Sub

        Private Sub Form_Load()
           'This works:
           VariableInModule = "Test"
           MsgBox "VariableInModule = " & VariableInModule
        End Sub

5. Press the F5 key to run the project. Note that the form load event executes
  as expected, and a message box is displayed showing the value of
  VariableInModule. However, clicking the form generates an error.
