BUG: Lines Drawn on Form Disappear After Menu Covers Them

• Microsoft Windows CE Toolkit for Visual Basic 6.0
• Microsoft Windows CE Toolkit for Visual Basic 5.0

SYMPTOMS

When a menu drops down and covers lines drawn directly on a form, the line that is covered will not be repainted correctly.

RESOLUTION

To avoid this problem, redraw the line in the Click event of the submenu. For example, if you have a File menu with a submenu named "New," add the following code for the "New" submenu Click event:

   Private Sub mnuNew_Click()
      'Normal New menu code here
      Drawline 0,0,1000,1000   'Redraw line.
   End Sub 

STATUS

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