URGENT: IIS vs. webmatrix server

[Jorge]

Hi,
I'm developing a web page application that runs 2 processeses. These
two process create postcript files, the first one creates a map and
the second one overlays data over that map.

Apparently my application was working fine when I ran it with the
webmatrix server however when I decided to use IIS to run the
application only one process ran.

Here's the code that is doing it:

public void CreateMapM(object sender, EventArgs e)
{
string programName1 ="pscoast.exe";
string programName2 = "psxy.exe";

string arg1 = @"-Jq-95/1:52000000 -R-130/-50/10/50
-B10g5 -G210/180/140";
arg1 += @"\ -I1/1/0/0/255 -K -N1 -N2 -P -S0/0/255
-W2/0/0/255";
arg1 += @" > c:\inetpub\wwwroot\temp\test.ps";

string arg2 = @"-R -Jq -O ";
arg2 +=
@"c:\inetpub\wwwroot\temp\gravitydata.dat";
arg2 += @" -G0/255/255 -Sc0.05c";
arg2 += @">> c:\inetpub\wwwroot\temp\TEMPO.ps";
//Create new processes info structure

ProcessStartInfo pscoastInfo = new ProcessStartInfo();
//Set the file name and arguments to each process

pscoastInfo.FileName = programName1;
pscoastInfo.Arguments = arg1;
pscoastInfo.RedirectStandardOutput = true;
pscoastInfo.UseShellExecute = false;

//Start pscoast process

Process pscoast = Process.Start(pscoastInfo);
string output1 = pscoast.StandardOutput.ReadToEnd();
pscoast.WaitForExit();

// Write pscoast process output
// to file

FileStream fs1 = new
FileStream(@"c:\inetpub\wwwroot\temp\TEMPO.ps",Fil eMode.Create,
FileAccess.Write);
StreamWriter w1 = new StreamWriter(fs1);
w1.Write(output1);

w1.Close();
fs1.Close();

ProcessStartInfo psxyInfo = new ProcessStartInfo();

//Set the file name and arguments of psxy process

psxyInfo.FileName = programName2;
psxyInfo.Arguments = arg2;
psxyInfo.RedirectStandardOutput = true;
psxyInfo.UseShellExecute = false;

//Start process psxy

Process psxy = Process.Start(psxyInfo);
string output2 = psxy.StandardOutput.ReadToEnd();
psxy.WaitForExit();

// Write psxy process output
// to file

FileStream fs2 = new
FileStream(@"c:\inetpub\wwwroot\temp\TEMPO.ps",Fil eMode.Append,FileAccess.Write);
StreamWriter w2 = new StreamWriter(fs2);
w2.Write(output2);

w2.Close();
fs2.Close();

}

Thanks in advance,

Jorge.
