【Escapist:003】C++ 仅仅使用 Windows API 创建一个窗口
仅仅使用 Windows API 创建一个窗口，并且让它显示在屏幕中央。代码：
程序代码：#include<Windows.h>
#pragma comment(linker, "/manifestdependency:\"type='win32' name='Microsoft.' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
const char WindowClassName[] = "WindowClass";
const char WindowCaption[] = "CreateWindowExA";
HINSTANCE InstanceHandle;
//HWND WindowHandle;
long __stdcall WindowProcess(HWND WindowHandle, unsigned int Message, unsigned int wParam, long lParam);
int __stdcall WinMain(HINSTANCE hInstance, HINSTANCE PreInstanceHandle, char* lpCmdLine, int nCmdShow)
{
InstanceHandle = hInstance;
WNDCLASSEXA WindowClass;
WindowClass.cbSize = sizeof(WNDCLASSEXW);
WindowClass.style = CS_HREDRAW | CS_VREDRAW;
WindowClass.lpfnWndProc = WindowProcess;
WindowClass.cbClsExtra = 0;
WindowClass.cbWndExtra = 0;
WindowClass.hInstance = InstanceHandle;
WindowClass.hIcon = LoadIconA(InstanceHandle, NULL);
WindowClass.hCursor = LoadCursorA(InstanceHandle, MAKEINTRESOURCEA(32512));
WindowClass.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
WindowClass.lpszMenuName = NULL;
WindowClass.lpszClassName = WindowClassName;
WindowClass.hIconSm = LoadIconA(InstanceHandle, NULL);
RegisterClassExA(&WindowClass);
HWND WindowHandle = CreateWindowExA(WS_EX_CLIENTEDGE, WindowClassName, WindowCaption, WS_OVERLAPPEDWINDOW, 0, 0, 750, 500, NULL, NULL, InstanceHandle, NULL);
if (!WindowHandle)
return 0;
ShowWindow(WindowHandle, SW_SHOW);
MSG Message;
while (GetMessageA(&Message, nullptr, 0, 0))
{
TranslateMessage(&Message);
DispatchMessageA(&Message);
}
return 0;
}
long __stdcall WindowProcess(HWND WindowHandle, unsigned int Message, unsigned int wParam, long lParam)
{
switch (Message)
{
case WM_CREATE:
{
RECT Rect;
GetWindowRect(WindowHandle, &Rect);
SetWindowPos(WindowHandle, HWND_TOP, ((GetSystemMetrics(SM_CXSCREEN) - Rect.right) / 2), ((GetSystemMetrics(SM_CYSCREEN) - Rect.bottom) / 2), Rect.right, Rect.bottom, SWP_SHOWWINDOW);
break;
}
case WM_PAINT:
{
PAINTSTRUCT PaintStruct;
HDC DCHandle = BeginPaint(WindowHandle, &PaintStruct);
//添加绘图代码
EndPaint(WindowHandle, &PaintStruct);
break;
}
case WM_DESTROY:
{
PostQuitMessage(0);
break;
}
default:
{
return DefWindowProcA(WindowHandle, Message, wParam, lParam);
}
}
return 0;
}

将代码拷贝到空白cpp文件中即可运行。
如果反响较高，我会详细出几期教程，谢谢~
