The information in this article applies to:

- Microsoft Visual Basic Learning Edition for Windows, version 6.0

-------------------------------------------------------------------------------

SYMPTOMS
========

When you shift focus from a Windowless TextBox on a Windowless UserControl to a
standard TextBox on a form, the caret is not visible in the form's TextBox. The
form's TextBox has the focus and the keyboard input will be directed to the
TextBox, but the caret is not present.

RESOLUTION
==========

Resolution #1
-------------

Set the Windowless property of the UserControl to False.

Resolution #2
-------------

Invoke the SetFocus method in the GotFocus event of the TextBox. For example:

     Private Sub Text1_GotFocus()
        Me.SetFocus
     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 Behavior
---------------------------

1. Start a Standard EXE project in Visual Basic. Form1 is created by default.

2. Choose Components from the Project menu, check "Microsoft Windowless Controls
  6.0," and click OK.

3. From the Project menu, add a new UserControl to the project.

4. Set the Windowless property of the UserControl to True.

5. Add a Windowless TextBox to the UserControl.

6. Close the UserControl window, and add an instance of the UserControl to
  Form1.

7. Add a standard TextBox to Form1.

8. Run the project. The caret should appear in the UserControl's TextBox.

9. Press the TAB key, or click on the form's Textbox. Note that the caret does
  not appear, although the TextBox will accept keyboard input.
