Hi, I have a program that is used to backup several files. And it runs constantly. I have made this program in c++. I m using windows.h only. I want to run this application background everytime the computer login. Means nothing shud come in task bar and no window sud open. Please tell me what code sud I add to my program to make it invisible. Can someone please help me with it. Regards -Aditya Raj

it's not making it invisible, just making it run as a service everytime the computer starts. I am not into Windows programming/C++ programming, but a random check on the web shows me a website you can reference http://www.muukka.net/programming/service.html hope it can guide you a bit.good luck

Is this a Win32 Console program, or an actual Win32 Application? In a Win32 Application, the ShowWindow() function tells Windows how to display the window of your program. Without it, the window (and it's corresponding taskbar) would not show. Or you could use ShowWindow() to hide your window by using the SW_HIDE parameter. As for running the program everytime Windows starts, it's as simple as putting a shortcut in your startup folder. If this is a Win32 Console program, then I think you would have to re-write the code to a Win32 Appliction in order to eliminate the black console window. Hope this helps, Tommy
