I am currently creating an ActiveX control, I would like some of the properties to display a list of options when used in Visual Basic or other Dev Environments.

i.e. When I select the property a combo box appears with the items.

Hi.
Add something similar to your ODL file:

      typedef [uuid(8237C324-0E9A-11d1-9583-006097B82032),
                  helpstring("ScanWizard Page Type")]
      enum {
            [helpstring("Black\\White")] swBW = 1,
            [helpstring("Greys")] swGrey = 2,
            [helpstring("Color")] swColor = 3,
      } swPageType;

      [ uuid(D18A08E5-0E72-11D1-9583-006097B82032) ]
      dispinterface IScanWiz
      {
            properties:
                  // NOTE - ClassWizard will maintain property information here.
                  //    Use extreme caution when editing this section.
                  //{{AFX_ODL_PROP(CScanWiz)
                  //}}AFX_ODL_PROP
                  [id(1)] swScanMode ScanMode;
                  [id(2)] boolean UseADF;
                  [id(3)] swScanType ScanType;
.
                  [id(8)] swPageType PageType;


.....
Be sure to generate the GUIDs for yourself with the GUID generator that comes with VC.
When your OCX will be placed in VB for example the property browser will show the values of the enumeration if that property is enumerated.
