It is good piece of code works like champ !!! I did test this code on my Pocket PC 2003 and it works perfect.

I am wondering if there is any VC++ / MFC alternative code for the same. It seems that DateTime, HttpWebRequest, Response .. etc are not available for MFC or Win32. I would really appreciate if someone could point me equalent Win32 / MFC API to acheivi this functionality.

I am facing the same problem in Intermec CN3 (Windows Mobile 5.0). When battery down, time settings revert to default value.

I tried the code you provide, but it is not working. Sometimes errors are coming…
1. PI invoke failed
2. Specified method not found.

Could you please help me to solve this issue. asap

Thanks and Regards

}
}

Note:I want to use my home server in place of “www.google.com”.

Now kindly guide me why the method “SetSystemTime()” is not working to set the PDA time?? I have used this code in “DeviceApplication” in VC#.NET environment.

public static string GetHeader(string url, string header)
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = “HEAD”;
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
string response_str = resp.Headers.Get(header);
resp.Close();
return response_str;
}

from MSDN:

The Close method closes the response stream and releases the connection to the resource for reuse by other requests.

You must call either the Stream..::.Close or the HttpWebResponse..::.Close method to close the stream and release the connection for reuse. It is not necessary to call both Stream..::.Close and HttpWebResponse..::.Close, but doing so does not cause an error. Failure to close the stream can cause your application to run out of connections.

Can someonne guide me what to do now.?? Can anyone provide me the source code in java or in othere language (so that can be called by java application)

Thanks,
