Hi! I'm trying to write a code which will converts doc files to docx. As far as I know, I can use ofc.exe for this purposes, but I can't run it from an aspx page.

I'm impersonating the user who has unrestricted rights (user is in a group of the local administrators), but the file is not converted. The strange thing is, that no error or output is generated. Where can be the problem? If you have a better way to convert doc to docx - please, tell me! =)

The code I use to run the ofc.exe is the following:

Process ofcProcess = new Process();
ofcProcess.StartInfo = new ProcessStartInfo();
ofcProcess.StartInfo.FileName = ofcLocation + @"\ofc.exe";
ofcProcess.StartInfo.WorkingDirectory = ofcLocation;
ofcProcess.StartInfo.UseShellExecute = false;
ofcProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
ofcProcess.StartInfo.RedirectStandardOutput = true;
ofcProcess.Start();
System.IO.StreamReader myOutput = ofcProcess.StandardOutput;
string m_output = myOutput.ReadToEnd();
ofcProcess.WaitForExit();
if (ofcProcess.HasExited)
{
    System.Diagnostics.EventLog.WriteEntry("MyEventLog", "OFC.exe output:\r\n" + m_output);
}
else
{
    System.Diagnostics.EventLog.WriteEntry("MyEventLog", "OFC.exe output:\r\nProcess haven't existed!");
}

After that the event log has entry: "OFC.exe output:".

P.S.: OS is Windows Server 2008 x64 with IIS7
