Capturing output of a command line app

[Peter S.]

Hello all,

I want to capture the output of a command line application in real time and
not all together after the app has finished (e.g. c:\dir *.* /s > logfile
and then load the contents of logfile) . All the examples I found out use
CreateProcess but the output of the command line is loaded at the end.

Thank you very much

[Peter S.]

Hello Ryan,

Yes if you please I would like the component you have. How can I get it?

Here are a couple of URLs, some of them may even be still valid:

TRedirector http://www.pana.com/robert/Dcomp.html
TGUI2Console www.delphipages.com in the 'NonVisual' section
code example: http://www.prel.btinternet.co.uk/downloads/console.zip

http://www.torry.net/tasks.htm, look for DosCommand

Hello Peter,

I downloaded doscommand and I would like to try TRedirector as well, but the
link is dead. Any other place where I can download it?

Thank you

I don't have any other link. Search for it via Google.

I've posted it to the attachments group for anyone who's interested.

Please note: I didn't write this, but I do use it. It does have it's problems
but I've never really found them to be show stoppers, just annoying.

HTH,
Ryan

Thank you Ryan but I need your advice....

I have a TMemo in a form and a button. In the OnClick of the button I write
:

var t : TEcecutionLibrary;
cmd : string;
begin
t := TExecutionLibrary(memo1); // my tmemo
t.command := cmd
t.execute;
..........................
end;

How can I use the t.OnLineAvailable???

Thank you

DosCommand worked better for my case than TRedirector.
However, the original doscommand version has an annoying
memory leak which would crash my app after 50,000 or more
calls. The corrected code can be found on the author's page
and is called doscommand_tk:

Hi Peter:

You might try the Doscommand.OnNewLine event instead of the OnTerminated.

Thats what I did!!!! When my dos programm runs it shows some infos about the
data it has read...these first lines appear in my memo after a few seconds
and not directly :o(. Do you know how to use TRiderector? an example maybe

Hi Peter,

I don't have the TRedirector component handy and its link
seems to be down at the moment. Any other source ?
For DosCommand, I use the following and it's pretty fast, at
least with netstat or any other regular dos stuff:
-----------------------------------------------------
procedure TForm1.Button1Click(Sender: TObject);
begin
DosCommand1.CommandLine := 'netstat -a';
DosCommand1.OutputLines := Memo1.Lines;
DosCommand1.Execute;
end;
-----------------------------------------------------

You have to declare a procedure on your form so that it follows the same
event declaration as the event OnLineAvailable.

What you may want to do is register the component in a package,
that way the IDE can create that for you.

The procedure you need to declare needs to look someting like this

Form1 = class(TForm)
private
procedure DoLineAvailable(Sender : TComponent; Line : string);
end;

HTH,
Ryan.
