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

Start a Standard EXE project in Visual Basic. Form1 is created by default.
Choose Components from the Project menu, check "Microsoft Windowless Controls 6.0," and click OK.
From the Project menu, add a new UserControl to the project.
Set the Windowless property of the UserControl to True.
Add a Windowless TextBox to the UserControl.
Close the UserControl window, and add an instance of the UserControl to Form1.
Add a standard TextBox to Form1.
Run the project. The caret should appear in the UserControl's TextBox.
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.
