按照文章《win32 application 添加一個icon 資源 resource》，

編譯之后，運行

HelloRes.exe

界面如下：

任務欄上面的圖標，如下：

修改后的hello.cpp中的代碼：

#include <windows.h> #include <stdlib.h> #include <string.h> #include <tchar.h> #include "resource.h" // 1LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,PSTR szCmdLine, int iCmdShow) {static TCHAR szAppName[] = TEXT("HelloWin");HWND hwnd;MSG msg;WNDCLASS wndclass;wndclass.style = CS_HREDRAW | CS_VREDRAW;wndclass.lpfnWndProc = WndProc;wndclass.cbClsExtra = 0;wndclass.cbWndExtra = 0;wndclass.hInstance = hInstance;//wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION); // 2wndclass.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_ICON1)); // 3wndclass.hCursor = LoadCursor(NULL, IDC_ARROW); wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);wndclass.lpszMenuName = NULL;wndclass.lpszClassName = szAppName;if (!RegisterClass(&wndclass)){MessageBox(NULL, TEXT("This program requires Windows NT!"),szAppName, MB_ICONERROR);return 0;}hwnd = CreateWindow(szAppName, // window class nameTEXT("The Hello Program"), // window captionWS_OVERLAPPEDWINDOW, // window styleCW_USEDEFAULT, // initial x positionCW_USEDEFAULT, // initial y positionCW_USEDEFAULT, // initial x sizeCW_USEDEFAULT, // initial y sizeNULL, // parent window handleNULL, // window menu handlehInstance, // program instance handleNULL); // creation parametersShowWindow(hwnd, iCmdShow);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;RECT rect;TCHAR msg[] = _T("Hello, World!"); switch (message){case WM_CLOSE:DestroyWindow(hwnd);break;case WM_DESTROY:PostQuitMessage(0);break;case WM_PAINT: hdc = BeginPaint(hwnd, &ps); TextOut(hdc, 50, 5, msg, _tcslen(msg)); EndPaint(hwnd, &ps); break; default:return DefWindowProc(hwnd, message, wParam, lParam);}return 0; }

共修改了3個地方 ，看代碼中的 //1 , //2 ,//3所在的語句。

編譯，運行之后的效果，如下:

主要修改的內容：

//wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION); // 2wndclass.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_ICON1)); // 3
