Editing listbox data

[scwizard]

I looked through the listbox controls on MSDN and they don't seem to have some kind of message like this:

SendMessage((HWND)ListBox, LB_SETTEXT, LBindex, (LPARAM)AString);

Easy question: So how do you edit a listbox item?
Hard question: How do you figure out where in the memory your program is storing the string for the listbox item?

How do you figure out where in the memory your program is storing the string for the listbox item?

I'm not sure I fully understand this question.

But anyway, unfortunately, there is no such animal as LB_SETTEXT. So, you may want to try the following LB edit implementation:

int iCurSel = SendMessage((HWND)lParam, LB_GETCURSEL, (WPARAM)0, 0L);
       	SendMessage((HWND)lParam, LB_INSERTSTRING, (WPARAM)(index), (LPARAM)"NewItem");
        SendMessage((HWND)lParam, LB_DELETESTRING, (WPARAM)(index+1), 0L);
        SendMessage((HWND)lParam, LB_SETCURSEL, (WPARAM)iCurSel, 0L);

That's exactly what I'm trying to avoid.

I know there's no such thing as LB_SETTEXT, but what I'm saying is there really should be.

But if there really isn't, how do I go about where in the memory my program is storing the string for a listbox item?

ReadProcessMemory is one way of finding out where your listbox strings are stored.
