wince+vs2005(c#),在程序里如何实现重启应用程序的功能
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·

[解决办法]
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();

vbnet 版的是调试过的,你看哪里翻译错了,自己改。
[解决办法]
调用 WINCE API接口 即可
