请教 关于LPCWSTR类型的赋值问题

一个windows的小窗口程序，在VS2010上面运行的，编译没通过， 都是提示LPCWSTR类型与char [8] 或者 const char [8]类型不兼容，无法转化。

我把那些字符串强制转化为LPCWSTR类型，虽然可以运行了，但是都是乱码...

我看视频教程里是在VC++ 6.0上面运行的，都没问题....
这个要怎么办啊？

代码：
#include<windows.h>
#include<stdio.h>

LRESULT CALLBACK WinLeeProc(
  __in  HWND hwnd,
  __in  UINT uMsg,
  __in  WPARAM wParam,
  __in  LPARAM lParam
);

int WINAPI WinMain(HINSTANCE hInstance,
                   HINSTANCE hPrevInstance,
                   LPSTR lpCmdLine,
                   int nCmdShow)
{
    WNDCLASS wincls;
        wincls.cbClsExtra = 0;
        wincls.cbWndExtra = 0;
        wincls.hbrBackground = (HBRUSH)GetStockObject(DKGRAY_BRUSH);
        wincls.hCursor = LoadCursor(NULL,IDC_CROSS);
        wincls.hIcon = LoadIcon(NULL,IDI_ERROR);
        wincls.hInstance = hInstance;
        wincls.lpfnWndProc = WinLeeProc;
        wincls.lpszClassName = "Lee2012";       //这里
        wincls.lpszMenuName = NULL;
        wincls.style = CS_HREDRAW | CS_VREDRAW;

    RegisterClass(&wincls);

    HWND hwnd;
    hwnd = CreateWindow("Lee2012","TestApplication 1",WS_OVERLAPPEDWINDOW,0,0,CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,hInstance,NULL);    //这里
    ShowWindow(hwnd,SW_SHOWMAXIMIZED);

    UpdateWindow(hwnd);

    MSG msg;
    while(GetMessage(&msg,NULL,0,0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return 0;
}


LRESULT CALLBACK WinLeeProc(
  __in  HWND hwnd,
  __in  UINT uMsg,
  __in  WPARAM wParam,
  __in  LPARAM lParam
)
{
    switch(uMsg)
    {
    case WM_PAINT:
        HDC hdc1;
        PAINTSTRUCT ps;
        hdc1 = BeginPaint(hwnd,&ps);
        TextOut(hdc1,0,0,"培训",strlen("培训"));    //这里..  还有好几个地方....
        EndPaint(hwnd,&ps);
        break;
    case WM_CHAR:
        char szChar[20];
        sprintf(szChar,"char is %d",wParam);
        MessageBox(hwnd,szChar,"linan01",0);
        break;
    case WM_LBUTTONDOWN:
        MessageBox(hwnd,"Left clicked","linan02",0);
        HDC hdc2;
        hdc2=GetDC(hwnd);
        TextOut(hdc2,0,50,"123456",strlen("123456"));
        ReleaseDC(hwnd,hdc2);
        break;
    case WM_CLOSE:
        if(IDYES==MessageBox(hwnd,"True Out?","linan03",MB_YESNO))
        {
            DestroyWindow(hwnd);
        }
        break;
    case WM_DESTROY:
        PostQuitMessage(0);
        break;
    default:
        return DefWindowProc(hwnd,uMsg,wParam,lParam);
    }
    return 0;
