BUG: "Member OPTION3 Is a Class Member" Error

• Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0

SYMPTOMS

If you associate a field from a table to an OptionGroup class in the Database Designer, and the ButtonCount property of the OptionGroup class is greater than two (2), after you add that table to a form's DataEnvironment, dragging and dropping that field onto a form causes the following error to occur:

Member OPTIONx is a class member.

RESOLUTION

Add the class from the Form Controls Toolbar or drag and drop the class from the Project Manager and set up the ControlSource property manually instead of using Intellidrop.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Behavior

1. Create an OptionGroup class with the following code:

   
         CREATE CLASS opt1 OF myopt1 AS OptionGroup 




2. In the Class Designer, set the ButtonCount property of the OptionGroup class to 3.



3. Save the class.



4. Create a .prg file and type in the following code:

   
         CLOSE ALL
         SET SAFETY OFF
         CREATE DATABASE testdata
         CREATE TABLE test (field1 N(1))
         DBSETPROP('test.field1', 'field', 'DisplayClassLibrary', 'myopt1.vcx')
         DBSETPROP('test.field1', 'field', 'DisplayClass', 'opt1')
         CREATE FORM myform NOWAIT
         KEYBOARD "{ALT+V}"+"{E}"        && In Visual FoxPro 6.0,
         KEYBOARD "{ALT+A}"+"{ALT+C}"    && use this line of code.
                                      && However, in Visual FoxPro 5.0,
        && KEYBOARD "{Tab}"+"{Enter}"+"{Tab}"+"{Enter}" && uncomment this line
                                                        && and comment the
                                                        && preceding lines of
                                                        && code.
        SET SAFETY ON 




5. Save the preceding as a .prg file and run the program.



6. When the Form Designer and DataEnvironment display, drag and drop field1 from the table onto the form.
