Capture output of launched external application? by V@no on 12-03-2006 at 09:07 AM
Hello!
I'm trying launch an external program via MP!L script. So far I found only one way to do so:
code:myprogram.exe returns some text which I need to capture. unfortunetly ShellExecute only returns error codes or such...
var objShell = new ActiveXObject("Shell.Application");
objShell.ShellExecute('C:\\myprogram.exe', '', '', "open", 0);
Is there a way launch an external application (with no window showed if possible) and capture the output?
Thank you.
P.S. I dont know advanced programming languages such as C or even VB...

code:
var Shell = new ActiveXObject('WScript.Shell');
var oExec = Shell.Exec("C:\\myprogram.exe");
Debug.Trace(oExec.StdOut.ReadAll());

Yes, that's it, very good.
Now, if I could get rid off the command prompt window it would be perfect!
Thanks

I think it might be possible to iterate through open windows, get the handle to the command prompt and hide/close it

yes, I've tryed that, but again, with "open" I can not capture the output...

I found a work around this...I'm using "open" instead of "exec", that allowes to run hidden command prompt window.
then I created a myprogram.bat file where I set command line to execute my program and redirect output into a file:
code:and finaly I read the output file in the script.
C:\myprogram.exe > C:\output.txt
Somebody might find this is useful, here is the script code:
code:
var outputfile = "C:\\output.txt";
var fso = new ActiveXObject("Scripting.FileSystemObject");
var Shell = new ActiveXObject('WScript.Shell');
var oExec = Shell.Run("C:\\myprogram.bat", 0, true);
var output = "";
if(fso.FileExists(outputfile))
output = fso.OpenTextFile(outputfile, 1, true, 0).fH.ReadAll();
