How to Disable Combo and List Boxes in Wizard-Generated Forms

MORE INFORMATION

Step-by-step procedure

1. On the File menu, click Open, and change Files of Type to Visual Class Library. In the \Vfp\Wizards\ directory, select Wizstyle.vcx. In the Open box, choose TXTBTNS as the Class Name. The Class Designer will appear and allow the editing of the wizard buttons.
2. Double-click any button. In the Object box, select TXTBTNS. In the Procedures box, select SETALLPROP. In this code, look for the following line (it is split here for readability):

      CASE ATC(m.oControlParent.Controls[m.i].BaseClass,
         "CheckBox,TextBox,OleBoundControl") # 0
             m.oControlParent.Controls[m.i].Enabled = THIS.EditMode
   						

3. Note that CheckBox, TextBox, and OleBoundControl are the only objects referenced here. Add "ComboBox, ListBox, EditBox" to this line of code.
4. Save the changes, and create or open a wizard-generated form. Add a combo box based on a field from a table. When you run the form, note that the combo box is disabled until you click the Edit button.
