Hi, I am new to VB & .net.

I need to create a simple application that will allow me to have a button pushed that reflects dos command and then the output reflected in a return box.  I also need to be able to add variables to the button(s) instructions.

if you need more info, please let me know.

Here's an example:

a gui interface to traceroute.
a button on the vb interface that runs traceroute, some text box for variables to use when button pushed (the i.p. address to be tracerouted)
a box that reflects the results and stays there until closed.

So basically you want to redirect the ouput from the console (command) window to some textbox.

here's an example that should work:

http://dotnet.mvps.org/dotnet/samples/miscsamples/downloads/RedirectConsole.zip

Note that in the sample. a new thread is created to read the output since the output is being dynamically generated. If you just tried to read the output, you could run into problems.

hope that helps..

well..that wasn't meant to be a joke. yes, the comments are in a different language (i'm not sure which one..) but the code is still in english, right? I mean you should be able to get an idea from that.

anyway, Here's another version of the same thing (slightly different):

http://tinyurl.com/4jwys

Everything is the same as the previous sample except the reading of the output. You should start the reading of the output in another thread since the output is being generated dynamically and it would freeze your application till the read is complete. Just use the code to start the process from the link above and use the threading technique that's in the sample that I sent you earlier. It should be easy to read. Let me know if you have any problems.

hope that helps..
Imran.

This really hasn't answered my question so I am leaving it open.
