SYMPTOMS
========

A Standard EXE or UserControl form contains a second UserControl. The second
UserControl contains a text box and a data control. You close all the forms and
then open the second UserControl. When you attempt to change the DataSource
property of the text box in the property window, the UserControl immediately
closes or an application error occurs that causes Visual Basic to stop
responding.

STATUS
======

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

Steps to Reproduce Behavior

  by default.

3. Add a TextBox and a Data Control to UserControl2.

4. Close the design window for UserControl2 and put a UserControl2 into
  UserControl1.

5. Close all visible design windows.

6. Open UserControl2 and select the TextBox.
