基本概念

Shell：

Shell 是一個用 C 語言編寫的程序，它是用戶使用 Linux 的橋梁。Shell 既是一種命令語言，又是一種程序設(shè)計語言。

Shell 是指一種應(yīng)用程序，這個應(yīng)用程序提供了一個界面，用戶通過這個界面訪問操作系統(tǒng)內(nèi)核的服務(wù)。

API

#include "stdio.h" //輸入和輸出 #include "assert.h" //用于驗證程序做出的假設(shè),并在假設(shè)為假時輸出診斷消息。 #include "windows.h" //window程序需要的重要頭文件，封裝了許多庫函數(shù)以及一些類，將一些復(fù)雜的工作由庫函數(shù)處理。 #include "shellapi.h" //Shell API

開發(fā)環(huán)境?

Visual Studio 2019?

操作步驟

1、創(chuàng)建新項目?

2、打開資源視圖

視圖->其他視圖->資源視圖

快捷鍵：Ctrl+Shift+E

3、新建對話框?

4、GUI設(shè)計

注：?

1、在屬性欄中找到對應(yīng)的Caption屬性便可以修改顯示文字

2、點擊左側(cè)的工具箱，可以拖動Button控件到界面上

源代碼

分析菜單選擇?

// 分析菜單選擇:switch (wmId){case IDM_ABOUT:DialogBox(hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About);break;case IDM_TOOL:DialogBox(hInst, MAKEINTRESOURCE(IDD_DIALOG1), hWnd, Tool);break;case IDM_EXIT:DestroyWindow(hWnd);break;default:return DefWindowProc(hWnd, message, wParam, lParam);}

消息處理

// “工具”框的消息處理程序。 INT_PTR CALLBACK Tool(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam) {UNREFERENCED_PARAMETER(lParam);printf("%ud",message);switch (message){case WM_INITDIALOG:return (INT_PTR)TRUE;case WM_COMMAND:if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL){EndDialog(hDlg, LOWORD(wParam));return (INT_PTR)TRUE;}else if (LOWORD(wParam) == IDC_BUTTON1) {HINSTANCE hRslt = ShellExecute(NULL, _T("open"),_T("calc.exe"), NULL, NULL, SW_SHOWNORMAL);assert(hRslt > (HINSTANCE)HINSTANCE_ERROR);}else if (LOWORD(wParam) == IDC_BUTTON2) {HINSTANCE hRslt = ShellExecute(NULL, _T("open"),_T("notepad.EXE"), NULL, NULL, SW_SHOWNORMAL);assert(hRslt > (HINSTANCE)HINSTANCE_ERROR);}else if (LOWORD(wParam) == IDC_BUTTON3) {HINSTANCE hRslt = ShellExecute(NULL, _T("open"),_T("Nslookup.EXE"), NULL, NULL, SW_SHOWNORMAL);assert(hRslt > (HINSTANCE)HINSTANCE_ERROR);}else if (LOWORD(wParam) == IDC_BUTTON4) {HINSTANCE hRslt = ShellExecute(NULL, _T("open"),_T("slmgr.vbs"), L"-xpr", NULL, SW_SHOWNORMAL);assert(hRslt > (HINSTANCE)HINSTANCE_ERROR);}break;}return (INT_PTR)FALSE; }
