SYMPTOMS

Access Keys (accelerators) for a UserControl do not work if the control is contained in an MFC Dialog.

CAUSE

This problem is due to mnemonic differences between MFC 4.2 and Visual Basic 5.0. These mnemonic differences are discussed in the following article in the Microsoft Knowledge Base:

145698 PRB: Mnemonic Differences Between MFC 4.0 and Visual Basic 4.0

Although this article describes a scenario where the roles of Visual Basic and MFC are reversed, the same problem is encountered when a Visual Basic- created control is contained in an MFC Dialog.

RESOLUTION

There is currently no known workaround for this problem.

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.

MORE INFORMATION

Steps to Reproduce Problem

  1. Create a new ActiveX Control project in Visual Basic.
  2. Set the AccessKeys property to "NM."
  3. Add a TextBox to the control.
  4. Compile the UserControl to an .ocx.
  5. Create a MFC Dialog application using the VC++ MFCAppWizard.
  6. Add the Visual Basic .ocx to the MFC dialog.
  7. Run the MFC application.
  8. Attempt to use the ALT+"N" or ALT+"M" key combinations. Note that the behavior is a system beep rather than a change in focus.
