Do i have achoice between Console or GUI application??

[Raghaw]

I have a application *.exe which is a GUI application. Now I need to convert it to work as both console and GUI i.e. if any commandline args are entered it will work as a console application if no commandline args are entered it need to work as GUI application

Just don't start the gui if the command lines argument are entered.
Where is the problem?
