A problem about changing a project from "debug" to "release"?

[HelloNet]

I want to release my project, so I select Project-Setting on the VC++'s menu and a dialog appears.
There is a "Settings For" combo box and its default setting is "Win32 Debug". I change it to "Win32 Release" and click OK button. But the compiler still use "Win32 Debug" while I rebuild this project.
How could I use "Win32 Release" to compile my project? Thanks!

Instead Project-Settings you should choose Build-Set Active Configuration

It will work.

I do it by your way and work well. Thanks!
