Process to export svn files hangs with Process.Start()

I try to execute a .cmd to export files from SVN, it works manually and in my local machine(WS2003 SP2 IIS Identiy: Local System), but it fails in the execution server (same configuration).

The script I execute is:

echo.%Date%-%Time%- Username %username%>>c:\vpcheckcode\logsvn.txt

svn export %svnUrl% %srcFolder% --force --username %usr% --password %psw%

If I try simply to copy a file, no svn, it works.

When I execute it manually it logs my user and it exports the files. On develop PC it doesn't log the user but it works, in execution server it doesn't log the user and it doesn't works.

I try to execute the .cmd in this way:

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.FileName = strFileName;
startInfo.WindowStyle = ProcessWindowStyle.Hidden;

startInfo.Arguments = svnUrl + " " + srcFolder+ " " + usr+" "+psw;

using (Process exeProcess = Process.Start(startInfo))
{
    pid = exeProcess.Id;
    EventLog.WriteEntry("VPCheckCodeSrvDll.ExecuteScriptSVN", "avviato pid svn: " + pid.ToString(), EventLogEntryType.Warning);

    if (!exeProcess.WaitForExit((int)_svnExportTimeout))
    {
        exeProcess.Kill();

The process hangs untill it has been killed.

Any suggestion?

I did something similar. Try the following:

Change : startInfo.Arguments = svnUrl + " " + srcFolder+ " " + usr+" "+psw;

to : startInfo.Arguments = String.Format("{0} \"{1}\" --username {2} --password {3}", svnUrl, srcFolder, usr, psw);

I am making the assumption that your usr and psw variables do not contain the parameter information for subversion. Also, my destination included the file name (I can't see your full command line as it is cut off) and also contained spaces, so I had to enclose it within quotes. Your svnUrl should have "%20" in place of spaces if you have any (again, the full URL is not visible).
