The MFCDialogVariableExtender object represents a variable code element of an existing MFC dialog box, providing access to the properties of that variable.

NoteNote

To retrieve the validation ranges for a specific variable in an MFC dialog box, see MFCDialogNumberVariableExtender object or MFCDialogStringVariableExtender object.

This example displays the control ID representing each variable of the dialog box implemented by the CAboutDlg class.

' Macro code.
Sub GetControlIDs()
    Dim vcCM as VCCodeModel
    Dim vcClass as VCCodeClass
    Dim mfcVar as VCCodeVariable
    vcCM = DTE.Solution.Item(1).CodeModel
    vcClass = vcCM.Classes.Find("CAboutDlg")
    For Each vcVar in vcCM.Variables
        MsgBox(vcVar.Extender("MFCDialogVariable").ControlID)
    Next
End Sub
