I am using BorlandC++ Builder3.
I am using TListBox to display text and highlight each line of text individually one at a time.
I am trying to simulate stepping through code.
My problem is that I am using a button on the screen to highlight each line of text, this is working OK, but I want to disable the ability of the mouse and the up and down arrow keys  to highlight the lines. I have tried disablying the ListBox, but this greys out the text and disables the scrollbar which I want to use.
Can anyone help???

Thanks in advance

John

one thought .. when the list box gets the focus, immediatlely set focus to your button.  That way, the list box can never recieve input focus and so you cannot move the selection up and down.  But that won't help with the mouse.

So I'd handle WM_KEYDOWN (move selection with keyboard arrow), WM_CHAR (move selection by typing letters), and WM_LBUTTONDOWN and WM_LBUTTONDLBCLK (change selection by clicking) and do not call the default processing (do nothing).

Handling the WM_LBUTTONDOWN and DBLCLK should solve the mouse as well (see second paragraph of my answer).

Anyway .. give it a go and see how you go.
