ControlType, AllowAdditions, AllowDeletions, AllowEdits Properties Example

The following example examines the ControlType property for all controls on a form. For each label and text box control, the procedure toggles the SpecialEffect property for those controls. When the label controls' SpecialEffect property is set to Shadowed and the text box controls' SpecialEffect property is set to Normal and the AllowAdditions, AllowDeletions, and AllowEdits properties are all set to True, the intCanEdit variable is toggled to allow editing of the underlying data.

Sub ToggleControl(frm As Form)
    Dim ctl As Control
    Dim intI As Integer, intCanEdit As Integer
    Const conTransparent = 0
    Const conWhite = 16777215
    For Each ctl in frm.Controls
        With ctl
            Select Case .ControlType
                Case acLabel
                    If .SpecialEffect = acEffectShadow Then
                        .SpecialEffect = acEffectNormal
                        .BorderStyle = conTransparent
                        intCanEdit = True
                    Else
                        .SpecialEffect = acEffectShadow
                        intCanEdit = False
                    End If
                Case acTextBox
                    If .SpecialEffect = acEffectNormal Then
                        .SpecialEffect = acEffectSunken
                        .BackColor = conWhite
                    Else
                        .SpecialEffect = acEffectNormal
                        .BackColor = frm.Detail.BackColor
                    End If
            End Select
        End With
    Next ctl
    If intCanEdit = IFalse Then
        With frm
            .AllowAdditions = False
            .AllowDeletions = False
            .AllowEdits = False
        End With
    Else
        With frm
            .AllowAdditions = True
            .AllowDeletions = True
            .AllowEdits = True
        End With
    End If
End Sub
