Can you explain why you derived CListBox do you have any intent of derived? WhiteSky

Again, you're using terms incorrectly. Saying you want to use a "modeless listbox" doesn't make any sense. I suspect what you want is to display a modeless *dialog* with a list box in it. Look up CDialog, and the differences between DoModal and a modeless dialog in MSDN. ¡El diablo está en mis pantalones! ¡Mire, mire!

Did you see DirectX section on the codeproject? WhiteSky

'register' inevitably means writing to the Windows Registry database. Hacking USER.DAT and the like from DOS is pretty much suicidal in term of Windows ever booting up again, so ultimately if you want register an ActiveX the registration process will need to run under Windows. There's nothing to stop you running regsvr32 from a command prompt or by use of ShellExecute(). It can be run with a quiet switch, /q I think, if you don't want any message boxes popping up. Nothing is exactly what it seems but everything with seems can be unpicked.

Whats header file of your program ? WhiteSky

For debug builds, it tells the compiler to use the crt debug "new" operator instead of the normal one. The debug version adds leak detection and maybe some other stuff. It also, as metioned, sets the THIS_FILE define to the current file. This information is used when dumping memory leak info. Mark "Posting a VB.NET question in the C++ forum will end in tears."

I am searching about an object on the codeproject and sudden see Motion Detection Algorithms[^] and remembered that a OP aksed about motion detection so I repled to you.;) WhiteSky
