hi guys.
I want to add a similar box to my C program.
Attachment 11574
I just copy and edited this image from a software just to show the box what exactly I want.
Can anyone tell me which WINDOWS API should I use to get the similar box..???

Thanks in advace.

Winapi, wxWidgets, MFC....lots of options.

Take a few tutorials on windows programming

Look here: Windows Application UI Development (Windows)

Especially "dialog boxes".
