C语言调用windows关机对话框

 具体代码如下：

/* *调用关闭系统的对话框 *write by:只爱阿蒙 e_mail:[e-mail] */#include <windows.h>#include "resource.h"//回调函数BOOL CALLBACK DiaProc(HWND hDlg, UINT uMsg, WPARAM wParam, LPARAM lParam);//声明typedef unsigned int(WINAPI *RUN)(UINT);HMODULE hShell32;RUN RunFileDlg;int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd ){DialogBoxParam(hInstance, MAKEINTRESOURCE(DLG_MAIN), 0, (DLGPROC) DiaProc, 0);return 0;}BOOL CALLBACK DiaProc(HWND hDlg, UINT uMsg, WPARAM wParam, LPARAM lParam){//HMODULE hDllInstance;switch (uMsg){case WM_INITDIALOG:hShell32 = LoadLibrary(TEXT("shell32.dll"));if (hShell32 == 0){MessageBox(hDlg, TEXT("装载Dll失败"), TEXT("错误哦"), MB_ICONERROR);return 0;}else{RunFileDlg = (RUN) GetProcAddress(hShell32,MAKEINTRESOURCE(60));RunFileDlg(0);SendMessage(hDlg, WM_CLOSE, 0, 0);}break;case WM_CLOSE:if (hShell32 != 0){FreeLibrary(hShell32);}EndDialog(hDlg, 0);break;}return FALSE;}

此代码也是“隐式”调用Dll的实例代码。
