Can anyone please let me know. What are the commands of qmake to run a Qt program in Windows

Eh… so what is it you are after, exactly? Do you want to run qmake, or some other Qt program? What do you want to achieve? Perhaps, you should reference this guide [catb.org] to try and formulate a better question.

Anyway, qmake is a command line application. You run it from a terminal or command line environment. If you installed the SDK, you will have something in your start menu (under the SDK folder somewhere) with an icon that looks like a small black window with a C:\ in it, and with the Qt version as its name. Start that, and in the resulting environment, type qmake.

Do you want to find this: http://doc.qt.nokia.com/latest/qmake-function-reference.html#system-command

system(command)
Executes the given command in a secondary shell, and succeeds if the command returns with a zero exit status; otherwise fails.

Thanx to all of you. I got the answer. Really very thanks. :)
