The information in this article applies to:

  • Microsoft Visual Basic Professional Edition for Windows 5.0

SYMPTOMS

If a DBCombo control contains items with the ampersand (&) character as part of the text and if the style of the DBCombo control is dbcDropdownList, then the text will not display correctly in the text box portion (the edit area) of the control. The drop-down list area is not affected.

This problem does not occur with the styles dbcDropdownCombo or dbcSimpleCombo.

RESOLUTION

To work around this problem, simply modify the text to include an extra "&" for every "&" that is in the original text as shown in the following code: 
   Private Sub DBCombo1_Click(Area As Integer)
   Dim i As Integer
   Dim s As String
   Dim c As String * 1

       If DBCombo1.Style = dbcDropdownList And Area = dbcAreaList Then
           s = DBCombo1.Text
           If InStr(s, "&") Then
               DBCombo1.Text = ""
               For i = 1 To Len(s)
                   c = Mid$(s, i, 1)
                   If c = "&" Then
                       DBCombo1.Text = DBCombo1.Text & "&&"
                   Else
                       DBCombo1.Text = DBCombo1.Text & c
                   End If
               Next
           End If
       End If

   End Sub
