APPLIES TO

Microsoft Access 97 Standard Edition

Moderate: Requires basic macro, coding, and interoperability skills.

SYMPTOMS

When you create a new menu bar in Visual Basic for Applications code, or when you set the Visible property of an existing menu bar to True, the current menu bar disappears. However, if you create a new menu bar or view an existing menu bar by pointing to Toolbars on the View menu, and then clicking Customize, the current menu bar remains visible along with the new one.

This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to the "Building Applications with Microsoft Access 97" manual.

RESOLUTION

You can set the Visible property of any existing menu bar in code to make it visible, but this method only allows you to display one menu bar at a time. When you set the Visible property of any menu bar to True, Microsoft Access automatically sets the Visible property of all other menu bars to False.

For example, assume your database contains two menu bars: MenuBar1 and MenuBar2. If MenuBar1 is displayed on your screen, the following line of code automatically sets the Visible property of MenuBar1 to False:

CommandBars("MenuBar2").Visible = True

If MenuBar2 is displayed on your screen, the following line of code automatically sets the Visible property of MenuBar2 to False:

CommandBars("MenuBar1").Visible = True

In order to display more than one menu bar at a time, you must create your new menu bar or view an existing one through the user interface as follows:

On the View menu, point to toolbars, and then click Customize.
In the Customize dialog box, select an existing menu bar, or click New to create a new one.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

Start Microsoft Access and open the sample database Northwind.mdb.
Create a new module.
On the Tools menu, click References.
In the References dialog box, select Microsoft Office 8.0 Object Library, and then click OK. If that reference is not listed in the Available References box, click the Browse button and search for the file, Mso97.dll.

Type the following line in the Declarations section of your module:

Public strCurrentMenuName As String

Type the following procedure:

      '*******************************************************************
      ' This procedure creates a new menu bar and makes it visible.
      '*******************************************************************

      Sub CreateMenuBar(strNewMenuName as String)
      Dim cmdNewMenu As CommandBar

      ' Set Global strCurrentMenuName to existing menu for use later when
      ' toggling.
      strCurrentMenuName = CommandBars.ActiveMenuBar.Name

      ' Create a new menu bar.
      Set cmdNewMenu = Application.CommandBars.Add(strNewMenuName, _
         msoBarFloating, True, False)
      With cmdNewMenu
        ' Set Protection property to no protection so users can customize
        ' it.
        .Protection = msoBarNoProtection
        ' Show new menu.
        .Visible = True
      End With
      End Sub

To test this function, type the following line in the Debug window, and then press ENTER:

CreateMenuBar "ExampleMenu"

A new floating menu bar is displayed on the screen, and the original menu bar is hidden from view.

NOTE: All command bars require a unique name. If you use the name of an existing command bar in the strNewMenuName argument of this procedure, you receive the following error message:

Run-time error '5':
Invalid procedure call or argument
To restore the original menu bar to the screen, type the following line in the Debug window, and then press ENTER:

CommandBars(strCurrentMenuName).Visible = True

Note that the original menu bar reappears, and your custom menu bar disappears.
