下面的代码在devcpp里面就可以顺利编译
/* BY beyondcode */
#include <windows.h>
#include <winbase.h>
#include <tchar.h>
#include <windef.h>
#include <stdio.h>
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
int WINAPI _tWinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nShowCmd )
{
static TCHAR szAppName[] = TEXT ("HelloWin");
HWND hwnd;
MSG msg;
WNDCLASS wndclass;
wndclass.style = CS_HREDRAW | CS_VREDRAW;

return 0 ;
}

ShowWindow (hwnd, nShowCmd) ;
UpdateWindow (hwnd) ;
while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage (&msg) ;
DispatchMessage (&msg) ;
}
return msg.wParam ;
}
LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
HDC hdc ;
PAINTSTRUCT ps ;

switch (message)
{
case WM_CREATE:
return 0 ;
case WM_PAINT:

return 0 ;
case WM_DESTROY:

return 0 ;
}
return DefWindowProc (hwnd, message, wParam, lParam) ;

}
但是在vscode里编译的时候就会出现以下错误信息:
C:\Users\lenovo\AppData\Local\Temp\ccLaMwRd.o: In function `WinMain':
c:/Users/lenovo/Desktop/SDK/VisualStudio/case1.cpp:27: undefined reference to `__imp_GetStockObject'

终端进程“C:\windows\System32\cmd.exe /d /c g++ -g c:\Users\lenovo\Desktop\SDK\VisualStudio\case1.cpp -o case1.exe”已终止,退出代码: 1。
wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
中的GetStockObject 未定义,看是不是缺失头文件
