SYMPTOMS
========

If a textbox on a form has its Locked property set to True, and the CTRL+C
shortcut is used to copy text in the textbox, the selected text will not be
copied to the clipboard.

RESOLUTION
==========

To work around this behavior, you must use the textbox's KeyDown event to check
for a CTRL+C key combination. If CTRL+C does occur, then you must
programatically put the selected text on the clipboard, as follows:

     If KeyCode = 67 And Shift = vbCtrlMask Then
         Clipboard.Clear
         Clipboard.SetText Text1.SelText
     End If

See the MORE INFORMATION section below for an example of the workaround.

STATUS
======

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

This bug was corrected in Visual Studio 6.0 Service Pack 3.

For more information about Visual Studio 6.0 Service Packs, please see the
following articles in the Microsoft Knowledge Base:

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

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

1. Create a new Visual Basic standard EXE project. Form1 is created by default.

2. Add a textbox to the default form.

3. Add the following code to the default form's Form_Load event:

  Private Sub Form_Load()
      Text1.Locked = True
      Text1.Text = "This is a test."
  End Sub

4. Run the program. While the program is running, highlight the text in the
  textbox and hit CTRL+C. Then, try to paste test into Notepad or another
  editor. You will note that nothing is pasted or some text from an earlier
  copy and paste operation is pasted from the clipboard.

5. To work around the problem, add the following code to the textbox's KeyDown
  event:

  Private Sub Text1_KeyDown(KeyCode As Integer, Shift As Integer)
     If KeyCode = 67 And Shift = vbCtrlMask Then
         Clipboard.Clear
         Clipboard.SetText Text1.SelText
     End If
  End Sub

6. Run the program and try the copy-paste operation again. This time it will
  work properly.

NOTE: Using the shortcut menu available with the right-mouse button will work
properly to copy text from a locked textbox.
