BUG: Lines Drawn on Form Disappear After Menu Covers Them

• Windows CE Toolkit for Visual Basic 5.0, version 1.0

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 "New" submenu, 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. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.
