Basic dialogbox shows unreadable letters

Im trying to compile this in VC++ Epress 2010 using file extension .c and project type as Win32 but still i get the following warnings

warning C4133: 'function' : incompatible types - from 'char [22]' to 'LPCWSTR'
warning C4133: 'function' : incompatible types - from 'char [5]' to 'LPCWSTR'

and when i run the program the text in the message box in unreadable Japanese or something. This code should not need a type cast to function running the C compiler???

Code:

#include <windows.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,     LPSTR lpCmdLine, int nCmdShow){    
   MessageBox(NULL, "Goodbye, cruel world!", "Note", MB_OK); 
   return 0;
}

Unicode Programming Summary
It means you should write UNICODE compatible code, rather than trying to just cast your way to making the compiler silent (but not removing any actual problems with the code).

How to tell VC++ what to use: I am unable to compile my very first Win32 code. Please help me out.

ty all works fine now!
