DOCUMENT:Q172111 11-JAN-2001 [vbwin] TITLE :FIX: VB5 Focus Not Returned to MDI Form After a Dialog Is Shown PRODUCT :Microsoft Visual Basic for Windows PROD/VER: OPER/SYS: KEYWORDS:kbGrpDSVB ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Learning Edition for Windows, version 5.0 - Microsoft Visual Basic Professional Edition for Windows, version 5.0 - Microsoft Visual Basic Enterprise Edition for Windows, version 5.0 - Microsoft Visual Basic Standard Edition, 32-bit, for Windows, version 4.0 - Microsoft Visual Basic Professional Edition, 16-bit, for Windows, version 4.0 - Microsoft Visual Basic Professional Edition, 32-bit, for Windows, version 4.0 - Microsoft Visual Basic Enterprise Edition, 16-bit, for Windows, version 4.0 - Microsoft Visual Basic Enterprise Edition, 32-bit, for Windows, version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== In the versions of Microsoft Visual Basic listed at the beginning of this article, if an MDI Form's Enabled property is set to False before a CommonDialog (such as ShowOpen) is displayed, the focus does not return to the MDI form, even if it is set programmatically. The subsequent behavior is that instead of giving the MDI form the focus, focus is given to the last window that had focus before the MDI form. RESOLUTION ========== The current workaround for this confirmed bug is to not set the MDI Form's Enabled property to False. The CommonDialog is Modal and automatically disables the MDI Form because of its Modal nature. Thus the workaround code for the code example in this article is: Private Sub Picture1_Click() CommonDialog1.ShowOpen End Sub STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Basic 6.0. MORE INFORMATION ================ Steps to Reproduce Behavior --------------------------- 1. Start Visual Basic. Form1 is created by default. 2. Add a MDI Form (MDIForm1) to the Project. 3. Make the MDI Form the Startup Form. 4. Add a Common Dialog Control (CommonDialog1) to the MDIForm1. 5. Add a Picture Box Control (Picture1) to the MDIForm1. 6. Add the following code to the Picture1_Click Event: Private Sub Picture1_Click() MDIForm1.Enabled = False CommonDialog1.ShowOpen MDIForm1.Enabled = True End Sub 7. Run the project. Note that the focus does not return to the MDIForm1. Instead the focus is sent to the next available window. NOTE: This behavior did not occur with the Cmdialog.vbx that shipped with Visual Basic 3.0.
