Thread: error 1421: "control ID not found"

I have a dialog box with two listbox controls. Both of them display disk directories and function well (with one exception. I can move from drive to drive, directory to directory perfectly.

Now, the exception. As I move down the list, clicking each item once with the mouse, if I click on the 9th item, the dialog closes and returns me to the main screen. I can scroll down with the arrow key and have no problems. I can click on any item (1 through 8) and (10 through the end of the list) without issue.

I placed a function in to return getLastError and it says the procedures last error was 1421. After searching, I found that 1421 means Control ID Not Found.

Any ideas what I may have done to cause this?

Here is the code from the .rc file:

                    WS_VSCROLL | WS_TABSTOP
END

I call the dialog with this:

Code:

					DialogBox( g_hInst, MAKEINTRESOURCE( IDD_FILE_XFER ), 
							hwndDlg, ( DLGPROC )XferDlgProc );

the procedure "XferDlgProc " is lengthy but I can post it if needed.

I would appreciate any hints. It has me stumped at this point.

I found it. I had left out a '}' and the compiler didn't catch it. I guess I should be more precise. Thanks for you interest.
