win32做API的时候出错了，哪位大神帮忙改一下，或者说一下
#include <Windows.h>#include <tchar.h>
LRESULT CALLBACK WndProc(HWND hWnd,UINT msg,WPARAM wParam,LPARAM mParam);
const TCHAR szWindowClass[]=L"第一个窗口";
const TCHAR szWindowTitle[]=L"主窗口题目";
int WINAPI_tWinMain(HINSTANCE hInstance,HINSTANCE hPreInstance,LPTSTR lpCmdLine,int nCmdShow)
{
WNDCLASSEX wcex={ 0 };
wcex.cbSize=sizeof(WNDCLASSEX);
wcex.style=CS_HREDRAW|CS_VREDRAW;
wcex.lpfnWndProc=(WNDPROC)WndProc;
wcex.hInstance=hInstance;
wcex.hIcon=LoadIcon(NULL,IDI_APPLICATION);
wcex.hCursor=LoadCursor(NULL,IDC_ARROW);
wcex.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH);
wcex.lpszClassName=szWindowClass;

szWindowTitle,

}

}
