控制台创建窗口（同时有控制台窗口和新创建的窗口）（项目类型：控制台应用程序）

#include "windows.h"  #include "TCHAR.h"  LRESULT CALLBACK WindowProc(HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM lParam);int _tmain(int argc, _TCHAR* argv[]){HINSTANCE hInstance;hInstance = GetModuleHandle(NULL);WNDCLASS Draw;Draw.cbClsExtra = 0;Draw.cbWndExtra = 0;Draw.hCursor = LoadCursor(hInstance, IDC_ARROW);;Draw.hIcon = LoadIcon(hInstance, IDI_APPLICATION);;Draw.lpszMenuName = NULL;Draw.style = CS_HREDRAW | CS_VREDRAW;Draw.hbrBackground = (HBRUSH)COLOR_WINDOW;Draw.lpfnWndProc = WindowProc;Draw.lpszClassName = _T("DDraw");Draw.hInstance = hInstance;RegisterClass(&Draw);HWND hwnd = CreateWindow(_T("DDraw"),           //上面注册的类名，要完全一致    L"绘制",  //窗口标题文字    WS_OVERLAPPEDWINDOW, //窗口外观样式    38,             //窗口相对于父级的X坐标    20,             //窗口相对于父级的Y坐标    640,                //窗口的宽度    480,                //窗口的高度    NULL,               //没有父窗口，为NULL    NULL,               //没有菜单，为NULL    hInstance,          //当前应用程序的实例句柄    NULL);              //没有附加数据，为NULL    // 显示窗口    ShowWindow(hwnd, SW_SHOW);// 更新窗口    UpdateWindow(hwnd);// 消息循环    MSG msg;while (GetMessage(&msg, NULL, 0, 0)){TranslateMessage(&msg);DispatchMessage(&msg);}}// 消息处理函数的实现  LRESULT CALLBACK WindowProc(_In_  HWND hwnd,_In_  UINT uMsg,_In_  WPARAM wParam,_In_  LPARAM lParam){switch (uMsg){case WM_DESTROY:{   PostQuitMessage(0);   return 0;}}return DefWindowProc(hwnd, uMsg, wParam, lParam);}

WinMain入口下创建窗口（只有新创建的窗口）（项目类型：windows应用程序）

#include <windows.h>#include "TCHAR.h" #include <stdio.h>LRESULT CALLBACK WindowProc(HWND hwnd,      // handle to windowUINT uMsg,      // message identifierWPARAM wParam,  // first message parameterLPARAM lParam   // second message parameter);int WINAPI WinMain(HINSTANCE hInstance,      // handle to current instanceHINSTANCE hPrevInstance,  // handle to previous instanceLPSTR lpCmdLine,          // command lineint nCmdShow              // show state){WNDCLASS wndcls;wndcls.cbClsExtra = 0;wndcls.cbWndExtra = 0;wndcls.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH);wndcls.hCursor = LoadCursor(NULL, IDC_CROSS);wndcls.hIcon = LoadIcon(NULL, IDI_ERROR);wndcls.hInstance = hInstance;wndcls.lpfnWndProc = WindowProc;wndcls.lpszClassName = _T("Hello");wndcls.lpszMenuName = NULL;wndcls.style = CS_HREDRAW | CS_VREDRAW;RegisterClass(&wndcls);HWND hwnd;hwnd = CreateWindow(_T("Hello"), L"World", WS_OVERLAPPEDWINDOW,0, 0, 600, 400, NULL, NULL, hInstance, NULL);ShowWindow(hwnd, SW_SHOWNORMAL);UpdateWindow(hwnd);MSG msg;while (GetMessage(&msg, NULL, 0, 0)){TranslateMessage(&msg);DispatchMessage(&msg);}return 0;}// 消息处理函数的实现  LRESULT CALLBACK WindowProc(  HWND hwnd,  UINT uMsg,  WPARAM wParam,  LPARAM lParam){switch (uMsg){case WM_DESTROY:{   PostQuitMessage(0);   return 0;}}return DefWindowProc(hwnd, uMsg, wParam, lParam);}
