Question 1: yes. You must use a RowSourceType of 0, 1 or 5 (array) to disable items.

Question 2: normally, using \] instead of \ would be sufficient, but unfortunately this is bugged. To circumvent it, you to have to build your list with RowSourceType = 0, insert items using .AddItem() method and use \] prefix to prevent mouse and keyboard access in disabled items.


>I have a form with a list box. I want to disable some of the items in the listbox. So I put a backslash in the front of all the items I need to disable. My code looks something like

>SELECT somefield FROM sometable WHERE conditions INTO CURSOR somecursor READWRITE
>SCAN
>    IF disable_condition
>        REPLACE somefield WITH "\" + somefield
>    ENDIF
>ENDSCAN
>
>WITH myListBox
>    .RowSourceType = 2 && alias
>    .RowSource = "somecoursor"
>ENDWITH

>
>When the listbox displays, it shows the backslash in the item and none of the items are disabled.

>Question 1: Is this expected behavior when using an alias? If so, I didn't find it documented (although I could easily have missed it).

>Second Try - Using an array
>I added an array as a form property and modified the code to be

>SELECT somefield FROM sometable WHERE conditions INTO CURSOR somecursor READWRITE
>SCAN
>    IF disable_condition
>        REPLACE somefield WITH "\" + somefield
>    ENDIF
>ENDSCAN
>
>DIME thisform.aMyListBox[RECCOUNT("somecursor")]  && Copy to array only copies to the current length of the array
>COPY TO ARRAY thisform.aMyListBox
>WITH myListBox
>    .RowSourceType = 5 && array
>    .RowSource = "thisform.aMyListBox"
>ENDWITH

>Now all the items I want to be disabled show in the disabled color. If you double-click on a disabled item nothing will happen.
