新手 编写一个简单的win32 application程序，书上的源代码，但是连接出错
das.obj : error LNK2001: unresolved external symbol __imp__MessageBoxA@16
LIBCMTD.lib(wwincrt0.obj) : error LNK2001: unresolved external symbol _wWinMain@16
Debug/das.exe : fatal error LNK1120: 2 unresolved externals
各种百度，但是还是解决不了

是不是建的控制台工程。。

就是Win32 Application啊，但是连接一直错误
LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
Debug/sad.exe : fatal error LNK1120: 1 unresolved externals
执行 link.exe 时出错.

应是你的工程出问题了。。要不重新建一遍。

不知您咋写的。。看代码。。

你建立的是控台程序了吧，至少程序找不到WinMain 入口
你的主函数是什么？是不是写着main，如果是，就看看学习下gui程序和cui程序的区别先

我错了WinMain大小写弄错了，我以为都是大写的。。。谢啦

#include<Windows.h>
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrewInstance, PSTR szCmdLine, int iCmdShow)
{
    static TCHAR szAppName[] = TEXT("HelloWin");
    HWND hwnd;
    MSG msg;
    WNDCLASS wndclass;
    wndclass.style = CS_HREDRAW | CS_VREDRAW;

    wndclass.lpszMenuName = NULL;
    wndclass.lpszMenuName = szAppName;


    if (!RegisterClass(&wndclass))
    {
        MessageBox(NULL, TEXT("This program requires Windows NT!"), szAppName, MB_ICONERROR);
        return 0;
    }
    hwnd = CreateWindow(szAppName, TEXT("The hello Program"),
        WS_OVERLAPPEDWINDOW,

        NULL,
        NULL,
        hInstance,
        NULL
        );
    ShowWindow(hwnd, iCmdShow);
    UpdateWindow(hwnd);
    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return msg.wParam;
}

LRESULT CALLBACK WinProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM IParam)
{
    HDC hdc;
    PAINTSTRUCT ps;
    RECT rect;
    switch (message)
    {
    case WM_CREATE:
        //PlaySound()
        return 0;
    case WM_PAINT:
        hdc = BeginPaint(hwnd, &ps);
        GetClientRect(hwnd, &rect);
        DrawText(hdc, TEXT("Hello,win7!"), -1, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER);
        EndPaint(hwnd, &ps);
        return 0;
    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;
    }
    return DefWindowProc(hwnd, message, wParam, IParam);
}
又是连接错误
