write to command line

This can and cannot be done depending on how you want to look at it.

Yes...it is possible to create a VB App that uses a console window for input/output.  HOWEVER, the VB app creates its own console window to achieve this.  Here are two links on the topic:

I could not find one example of a VB App sending output to the console window that it was executed from.

One sloppy possiblity that will definitely not be foolproof:

Use the FindWindow API to get a handle to the command window.  Put the message you want in the clipboard.  Activate the command window.  Use send keys to Edit --> Paste your message into the command window.

Any Experts want to implement that? =)

Questioner:
Can I ask what is the intention you implement this method?

What did you decide to do Mittel?

To fantasy: I wanted to write an application like that using C where you can write back to the command window.

To idle mind: Although your solutions sounded very promising, I ended up just writing to a log file.
