SetDlgItemText()

I have this code in my dialog box function:

Code:

---

case WM_INITDIALOG:
                        SendDlgItemMessage(hdwnd, IDD_LB1, LB_ADDSTRING, 0, (LPARAM)books[0]);
                        SendDlgItemMessage(hdwnd, IDD_LB1, LB_ADDSTRING, 0, (LPARAM)books[1]);
                        SendDlgItemMessage(hdwnd, IDD_LB1, LB_SETCURSEL, 0, 0);
                        SetDlgItemText(hdwnd, IDD_EB1, books[0]);
                        return 1;

---

the dialog box contains a list box and an edit box(plus some push buttons). The program compiles and links with no errors or warnings but when I run it and select the menu item which activates the dialog box I get an error message form windows saying error in kernel dll. If I remove the SetDlgItemText() The program works fine. The point of the SetDlgItemText is to initialise the edit box so it has the first string thats in the list box.

As a short term fix I'll just leave it out, but would like some suggestions????

Did you try

SendDlgItemMessage(hdwnd, IDD_EB1,
WM_SETTEXT, 0,(LPARAM)books[0]); ?


What is books[0] ?

THat works, thanks, any ideas why the other doesn't?
books[] is just an array of strings(book titles).

It may not realise that Books is a multi dimensional array.

So it may not stop at the end of the Books[0], start of Books[1], string but use the rest of the memory allocated to the array. This may be bigger than is allowed / allocated for a string in the ctrl.
I know Tree-views can't have more that 32k of items so there may be a limit.

Try using a temp string to add the item to the ctrl.
