Cannot convert parameter 2 from 'const char [1

2019-07-05 14:28发布

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?

There steps below worked for me:

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

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

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

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