Response to: fail to debug the program

Revision 1
Looks like you tried to run your program in debug mode (e. g. by pressing F5 or selecting [Debug]->[Start Debugging] from the menu), but built it in release mode.

Check your toolbar for text boxes: there are normally three, and one of them should either read Release or Debug. If it's Release, switch to Debug instead. If not, there must be another problem in your project settings.
