MORE INFORMATION

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following sample Visual Basic for Applications macro demonstrates two groups of check boxes on a form. One group contains check boxes named Yes, No, and Undecided; the other group contains check boxes named True and False. When you select one of the check boxes in the group, the other check boxes are cleared.

   Sub ToggleCheckBoxOnEntry()
      Dim fFields As FormFields
      Dim fSelectedField As FormField
      Set fFields = ActiveDocument.FormFields
      For Each fSelectedField In Selection.FormFields
         ' Form field must be a check box.
         If fSelectedField.Type = wdFieldFormCheckBox Then
            ' Go to the case for the currently selected group.
            Select Case fSelectedField.Name
               ' Yes, No, or Undecided check box group.
               Case "Yes", "No", "Undecided"
                  ' Clear all values.
                  fFields("Yes").CheckBox.Value = False
                  fFields("No").CheckBox.Value = False
                  fFields("Undecided").CheckBox.Value = False
               ' True or False check box group.
               Case "True", "False"
                  ' Clear all values.
                  fFields("True").CheckBox.Value = False
                  fFields("False").CheckBox.Value = False
               ' You can add other Case statements for other groupings.
               ' For example:
               'Case
               '   <Code>
               'Case
               '   <Code>
               Case Else
            End Select
            ' Check the selected formfield.
            fSelectedField.CheckBox.Value = True
         End If
      Next
   End Sub
				

To use this macro for any check box grouping within your document, assign ToggleCheckBoxOnEntry() as the Entry macro for every Check Box Form Field in the group.
