SYMPTOMS

In Visual FoxPro 3.0 the selected item in a list box can be initialized by placing the following code in the Form Init or the List box Init:

   THISFORM.List1.Selected(1) = .T.

This does not work in Visual FoxPro version 5.0.

RESOLUTION

Place the following code in the Activate method of the form. The variable acts like a switch so that the code is executed only when the form is first instantiated. The variable switch should be added to the form as a property. Switch is initialized to false.

   IF !THISFORM.switch
     THISFORM.List1.Selected(1)= .T.
     THISFORM.switch = .T.
   ENDIF

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Steps to Reproduce Behavior

Create a form and add the employee table to the DataEnvironment.
Add a list box to the form and set its RowSourceType to 6-Fields. Set its RowSource to employee.emp_id.
Place the following code in the Init of the form or the Init of the list box.
```
      THISFORM.List1.Selected(1)= .T.
						
```

Note that when the form is run, the first item is not selected.
