BUG: WizardBar Notification Slows Down Dialog Editor

 Last reviewed: July 31, 1997
Article ID: Q170511
The information in this article applies to:
  • Microsoft Visual C++, 32-bit Editions, version 5.0

SYMPTOMS

You may experience significantly slow performance when using the dialog editor in Visual C++ 5.0 if the projects you are using have several complex dialog boxes that use many controls. You might experience this slowness when you change from one control to another, when you start the Class Wizard, or when you access the properties of a control.

CAUSE

Complex queries need to update the WizardBar while the Dialog Editor is running, and this slows performance.

RESOLUTION

You can work around this problem by disabling the Wizard Bar as follows:

  1. On the Tools menu, select Customize.
2. In the Customize dialog box, select the Toolbars tab. 3. In the Toolbars list, scroll to the Wizard Bar check box and 
   de-select it.
4. Shut down Developer Studio and restart. 
   NOTE: The Wizard Bar will not be disabled until you shut down
   Developer Studio.
This should help resolve the main symptoms.

Double-clicking a control in the Resource Editor will re-invoke hidden WizardBar functionality (the WizardBar will not be displayed). To stop this behavior:

  1. Always use Ctrl+Tab to toggle between two windows.

-or-

  1. Disable the "Double-click in dialog editor edits code (MFC only)" option. To do this, on the Tools menu, select Options, select the Compatibility tab, and then de-select the "Double-click in dialog editor edits code (MFC only)" check box.

Finally, deleting or renaming the .CLW (Class Wizard) file may provide some relief. The .CLW file is located in the same directory as your project's files (.DSW and .DSP). It is possible to use a batch file that can be called from a toolbar button that is designed to do this. If you do this, a new CLW file will be generated every time you use the Class Wizard.
