Cannot convert parameter 2 from 'const char [14]' to 'LPCWSTR'

Question

I am getting this error:

cannot convert parameter 2 from 'const char [14]' to 'LPCWSTR'

With the code below. It is supposed to be C but at best visual studio 2012 offers an empty c++ project:

#include "windows.h"

int WINAPI WinMain (HINSTANCE hinst, HINSTANCE hprevinst, LPSTR cmdline, int showcmd)
{
    MessageBox(NULL, "Merhaba Dunya", "Merhaba", MB_OK);
    return 0;
}

What is incorrect?

It seems your current settings are set up so that WinAPI functions expect wide strings:

MessageBox(NULL, L"Merhaba Dunya", L"Merhaba", MB_OK);

@MonsterMMORPG I don't know what do you mean by that... what's a "native C IDE"? How would this have anything to do with the IDE? – Mar 24 '13 at 05:08

Right click on your project, go to properties under configuration properties -> General and change character set to Use multi-byte character set.

There steps below worked for me:

Right click on your Project in Solution Window, then select Properties menu item.
Click on General under "Configuration Properties" in Property Pages
At "Character Set" setting: change "Use Unicode Character Set" to "Use Multi-Byte Character Set", then click on OK button
Rebuild your project to see how it works
