I need a plumbep :P (Problems with Pipes)

Hey everyone. I have the following function that is part of my CONNECTION class:

Code:

---

int CONNECTION::SendCGI()
{
        RealFile = "C:\\SWS\\Webroot\\samplephp.php";

        char psBuffer[128];
        FILE * hPipe;
        string CGIInterpreter = "\"";                                                                // Put quotes around the name of the interpreter       
        CGIInterpreter += "C:\\PHP\\php.exe";                                        // Interpreter
        CGIInterpreter += "\" ";                                                        // End quote
        CGIInterpreter += RealFile;                                                        // Add the file to be interpreted

        if ((hPipe = _popen(CGIInterpreter.c_str(), "r")) == NULL)                       
        {                                                                                                                        // Open a pipe
                Beep(80,1000);
        }
        else
        {
        while (!feof( hPipe ))                                                                                // Loop until output finishes
        {
                if( fgets( psBuffer, 128, hPipe) )                                                // Get part of the output
                {       
                        cout << psBuffer;        // Send it
                }
        }
        fclose(hPipe);                                                        // Close pipe       
        }                                                                                                        // Return true for now
        return true;
}

The code runs as part of an NT service and is supposed to send a file to a CGI interpreter and pipe its output to be sent back to the browser.

When that code is run from the server all I get is the beep. But if I copy everything from the function and run it inside 'main()' as part of a stand alone application it runs fine and gives the expected output.

I don't use any of the variables externally (for now, I will when its working) yet it wont work when run as a service.

Theres nothing wrong with the service code or anything because I can do everything else, just not this. Does anyone have any idea why I might be having these problems?

[edit] lol damn typo in the title, now no one will read it[/edit]

From MSDN
Note If used in a Windows program, the _popen function returns an invalid file pointer that will cause the program to hang indefinitely. _popen works properly in a Console application. To create a Windows application that redirects input and output, see Creating a Child Process with Redirected Input and Output in the Platform SDK.

Yeah I've read that before on MSDN actually, but as an NT service its supposed to be a console application. It is called though main just like a normal console app. and is compiled in the same way, so I didn't think that would be a problem.

The server doesn't hang though, it goes though very fast and beeps because the pipe couldn't be created (but when run as a non-serivce it doesn't).
