使用紧凑的框架再次从Main（）运行主表单

Question

I'm developing application for devices that use Compact Framework of C#. I need to restart my application or run Application.run with main form from Main method again so that it can be updated. I can't use Application.Restart() or just Application.Run() as both aren't available in compact framework. I have tried to use:

[DllImport("coredll.dll")]
    private static extern bool CeRunAppAtTime(string pwszAppName, DateTime lpTime);
    var time = DateTime.Now.AddSeconds(15);
    CeRunAppAtTime(fullAppName, time);

but this isn't working. Also tried:

rocessStartInfo Info = new ProcessStartInfo();
Info.Arguments = "/C ping 127.0.0.1 -n 2 && \"" + fullAppName + "\"";
Info.FileName = "cmd.exe";
Process.Start(Info);
Application.Exit(); 

but this didn't also work and gave Win32Error.

Has anyone got any other idea to try or am I doing something wrong with mentioned solutions? Is there a way to execute Application.Run(MyForm) again after Myform.Close() has been run?

Device I use runs on Windows Embedded Handheld 6.5 Professional CE OS 5.2.29094

Answer 1

CeRunAppAtTime takes in a SYSTEMTIME structure, not a managed DateTime, so your first call is definitely going to fail.

The second looks like you're expecting the CE console to be pretty robust. Is this a vanilla CE device? If so, the call probably won't work but why not just call to launch your app? If it's Windows Mobile, where the OS would prevent a second instance from running, then cmd.exe doesn't even exist (nor does ping ) so that would be a failure point.

Your first path is the route I'd go. Just fix it so the P/Invoke takes in a long and pass it a SystemTime value instead of a managed DateTime .
