String tables doesn't work. Reading a tutorial...

I am learning Win32 programming by reading a tutorial, and I came to a point where they teach you about string tables. I am using Visual Studio 2010.
The error is that LPWSTR isn't compatible with an argument type of char. My guess is that the code is outdated, as the tutorial was created using Visual Studio 6. How can I make it work?
Here is the code:

Code:

//---------------------------------------------------------------------------
#include <windows.h>
#include "resource.h"

//---------------------------------------------------------------------------
char AppCaption[40];
LRESULT CALLBACK WndProcedure(HWND hWnd, UINT uMsg,
			      WPARAM wParam, LPARAM lParam);
//---------------------------------------------------------------------------
INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
	MSG        Msg;
	HWND       hWnd;
	WNDCLASSEX WndClsEx;
	LPCTSTR ClsName = L"ResFund";

	LoadString(hInstance, IDS_APP_NAME, AppCaption, 40); // This is where the first error comes in - on 'AppCaption'.

	// Create the application window
	WndClsEx.cbSize        = sizeof(WNDCLASSEX);
	WndClsEx.style         = CS_HREDRAW | CS_VREDRAW;
	WndClsEx.lpfnWndProc   = WndProcedure;
	WndClsEx.cbClsExtra    = 0;
	WndClsEx.cbWndExtra    = 0;
	WndClsEx.hIcon         = LoadIcon(hInstance,
				 MAKEINTRESOURCE(IDI_RESFUND2));
	WndClsEx.hCursor       = LoadCursor(NULL, IDC_ARROW);
	WndClsEx.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
	WndClsEx.lpszMenuName  = MAKEINTRESOURCE(IDR_MAINFRAME);
	WndClsEx.lpszClassName = ClsName;
	WndClsEx.hInstance     = hInstance;
	WndClsEx.hIconSm       = LoadIcon(hInstance,
					  MAKEINTRESOURCE(IDI_RESFUND2));

	// Register the application
	RegisterClassEx(&WndClsEx);

	// Create the window object
	hWnd = CreateWindowEx(0,
                              ClsName,
                              AppCaption,
                	      WS_OVERLAPPEDWINDOW,
                              CW_USEDEFAULT,
                              CW_USEDEFAULT,
                              CW_USEDEFAULT,
                              CW_USEDEFAULT,
                              NULL,
                              NULL,
                              hInstance,
                              NULL);
	
	// Find out if the window was created
	if( !hWnd ) // If the window was not created,
		return FALSE; // stop the application

	// Display the window to the user
	ShowWindow(hWnd, nCmdShow);// SW_SHOWNORMAL);
	UpdateWindow(hWnd);

	// Decode and treat the messages
	// as long as the application is running
	while( GetMessage(&Msg, NULL, 0, 0) )
	{
             TranslateMessage(&Msg);
             DispatchMessage(&Msg);
	}

//	return Msg.wParam;
    return 0;
}
//---------------------------------------------------------------------------
LRESULT CALLBACK WndProcedure(HWND hWnd, UINT Msg,
			   WPARAM wParam, LPARAM lParam)
{
    switch(Msg)
    {
    case WM_DESTROY:
        PostQuitMessage(WM_QUIT);
        break;
    default:
        // Process the left-over messages
        return DefWindowProc(hWnd, Msg, wParam, lParam);
    }
    // If something was not done, let it go
    return 0;
}
//---------------------------------------------------------------------------

Modern visual studio implementations default to using UNICODE, where VC6 used plain old ASCII.

visual studio - How do I turn off Unicode in a VC++ project? - Stack Overflow

Or you could just make your code UNICODE compatible by using _T or _TEXT
Unicode Programming Summary
Generic-Text Mappings in Tchar.h

Turning the code into Unicode was too complicated for me at this point, so I turned the Unicode off.
The program works fine now.
Thanks.
