break;
}
case WM_DESTROY:

ShowWindow(hwnd,SW_SHOW);
UpdateWindow(hwnd);
MSG msg;
while (GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}

return msg.wParam;
}

提示什么错误？

[解决办法]
LRESULT CALLBACK WNDFUN(HWND hWnd,UNIT msg,WPARAM wparam,LPARAM lparam);你有注册么?
[解决办法]
你的代码中主要有两个错误，看起来象你粗心的打字错误
一是将UINT写成UNIT，另一个是将;写成:
所以造成编译出错,修正后的代码如下：

C/C++ code

#include "windows.h"LRESULT CALLBACK WNDFUN(HWND hWnd, UINT msg, WPARAM wparam, LPARAM lparam){    switch(msg)    {        case WM_PAINT:        {            HDC hdc = GetDC(hWnd);            SetBkMode(hdc, TRANSPARENT);            TextOut(hdc, 20, 20, "明日科技有限公司", 16);            DeleteDC(hdc);            break;        }        case WM_CLOSE:        {            DestroyWindow(hWnd);            break;        }        case WM_DESTROY:        {            PostQuitMessage(0);            break;        }        default:            return DefWindowProc(hWnd, msg, wparam, lparam);    }    return 0;}int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,    LPSTR lpCmdLine, int nCmdShow){    WNDCLASS wndcls;    wndcls.style = CS_DBLCLKS | CS_VREDRAW | CS_HREDRAW;    wndcls.lpszMenuName = NULL;    wndcls.lpszClassName = "CustomWnd";    wndcls.lpfnWndProc = WNDFUN;    wndcls.hInstance = GetModuleHandle(NULL);    wndcls.hIcon = NULL;    wndcls.hCursor = NULL;    wndcls.hbrBackground = (HBRUSH)GetStockObject(GRAY_BRUSH);    wndcls.cbClsExtra = 0;    wndcls.cbWndExtra = 0;    RegisterClass(&wndcls);    HWND hwnd;    hwnd = CreateWindow("CustomWnd", "Win32APP",        WS_CAPTION | WS_OVERLAPPEDWINDOW | WS_SYSMENU, 50, 50, 500, 500, NULL,        NULL, wndcls.hInstance, NULL);    ShowWindow(hwnd, SW_SHOW);    UpdateWindow(hwnd);    MSG msg;    while (GetMessage(&msg, NULL, 0, 0))    {        TranslateMessage(&msg);        DispatchMessage(&msg);    }    return msg.wParam;}

WM_PAINT事件里最好不要用GetDC来获取hdc,推荐用BeginPaint和EndPaint。
