Sorry if my question is stupid, I'm a newbee. I'd like to know how to create a quiet program. I mean I don't want the DOS window to appear. I just want some instructions to be executed without any user interaction. How is this possible?

Hi,

I guess you want to execute your application in hidden / invisible mode. Windows programming have different ways to hide the command window from showing on executing an application. Using ShellExecute you can specify your options while running an application.

Example:

ShellExecute(NULL, "open","myfile1.exe", NULL, NULL, SW_HIDE);

Thanks for the advice.
To avoide the black dos window, I created a windows application instead of a dos application (using Dev-C++).
Plus, I send all my commands with ShellExecute.
Works fine, my program is totally invisible.
Thank you Rajeev

You are most welcome..
