Prevent console open on popen?

[philipwayne]

Is there a way I can prevent the console from opening when I use popen or would I have to do that in the program I am opening?

For which purpose you want to do this things, if I know I can tell the better solution for you

A PHP viewer type deal. Not really to sure how to explain it but basically:
We type PHP source on one side of the application and hit a button then the other side displays the output.

If you need/want to see the program its here ( do note PHP must be installed and on the path ) compiled on windows.

When I execute the code the PHP console opens and closes.

What command line do you use to execute the code?
What function call do you use to run that command?
Does this have to be portable or is it Windows only?

[philipwayne]

Command line is "php FILE".
Function is _popen/fputs not sure which one you meant.
Windows is fine I'm sure I can find the linux way.

void HPreview::updatePage( )
{
    FILE *fp1 = fopen( "source", "w" );
    fputs( this->input->toPlainText( ).toStdString( ).c_str( ), fp1 );
    fclose( fp1 );
 
    char buffer[1024];
    QString output( "" );
    long length;
 
    FILE *fp = _popen( "php source", "r" );
 
    while( fgets( buffer, sizeof( buffer ), fp ) != NULL )
    {
        output.append( buffer );
    }
 
    fclose( fp );
 
    this->output->setHtml( output );
}
 

I doubt it matters but I'm using the Qt framework.

You may have to do some experimentation but I think you could achieve what you want using CreateProcess. But you would have to create your own pipe for stdin/stdout first.

Okay, thank you I'll look in to that.
