为什么我写的windows窗口无法运行

永世不结婚

#include<Windows.h>
LRESULT CALLBACK Wndproc(HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain(HINSTANCE hlnstance,HINSTANCE hPrevlstance,PSTR szCmdLine,int iCmdShow)
{
        static TCHAR szAppName[] = L"MyWindoww";
        HWND hwnd;
        MSG msg;
        WNDCLASS wndclass;
        wndclass.style = CS_HREDRAW | CS_VREDRAW;
        wndclass.lpfnWndProc = Wndproc;
        wndclass.cbClsExtra = 0;
        wndclass.cbWndExtra = 0;
        wndclass.hInstance = hlnstance;
        wndclass.hIcon = Loadlcon(NULL, IDI_APPLICATION);
        wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
        wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
        wndclass.lpszMenuName = NULL;
        wndclass.lpszClassName = szAppName;
       
        if(!RegisterClass(&wndclass))
        {
                MessageBox(NULL, TEXT("HHHHHHHH"), szAppName, MB_ICONERROR);
                return 0;
        }

        hwnd = CreateWindow(szAppName, TEXT("huhao"), WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hlnstance, NULL);
        while (GetMessage(&msg,NULL,0,0))
        {
                TranslateMessage(&msg);
                DispatchMessage(&msg);
        }
        return msg.wParam;
}
LRESULT CALLBACK Wndpoc(HWND hwnd,UINT message,WPARAM wparam,LPARAM lparam)
{
        HDC hdc;
        PAINTSTRUCT ps;
        RECT rect;
        switch (message)
        {
        case WM_PAINT:
                hdc = BeginPaint(hwnd, &ps);
                GetClientRect(hwnd, &rect);
                DrawText(hdc, TEXT("jjjjjjjjjj"), -1, &rect, DT_CENTER | DT_VCENTER | DT_SINGLELINE);
                EndPaint(hwnd, &ps);
                return 0;
        case WM_DESTROY:
                PostQuitMessage(0);
                return 0;

        }
}

猫和狼

最后一行加上return DefWindowProc（hdc，message，wParam，lParam）；

临时号

以后细心一点,这个代码里好多I被写成了l,这个是改完后的代码,可以显示窗口了,
