数据下载完成后，我要控制应用程序立即重启，但是不知道如何实现重启应用程序的功能。
请懂的帮忙，谢谢·
------解决方案--------------------
可以再创建一个辅助进程（assistant process）来完成这件事吧。
在辅助进程中完成 关闭和创建 业务进程的功能。
TerminateProcess // 关闭进程
CreateProcess // 创建进程
这是WinCE的API，c#.net也许有自己的关闭和创建进程的封装函数接口。

VC的代码
- C/C++ code
1、重启按钮事件中添加代码： g_bIsRunAgain=true;//控制是否重新运行的变量 this->SendMessage(WM_CLOSE); 2、在OnClose()消息处理中加入代码： if(g_bIsRunAgain) { char pBuf[MAX_PATH]; //存放路径的变量 GetCurrentDirectory(MAX_PATH,pBuf); //获取程序的当前目录 strcat(pBuf,""); strcat(pBuf,AfxGetApp()->m_pszExeName); strcat(pBuf,".exe"); CString strPath= (CString) pBuf; STARTUPINFO StartInfo; PROCESS_INFORMATION procStruct; memset(&StartInfo, 0, sizeof(STARTUPINFO)); StartInfo.cb = sizeof(STARTUPINFO); ::CreateProcess( (LPCTSTR) strPath, NULL, NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS, NULL, NULL, &StartInfo, &procStruct); } CDialog::OnClose();
