How to catch keyboard - on a console application? [message #6941]

Hi all!

Last time I asked how to get keyboard input via Ctrl. The solution was easy - only overwrite the Key-Method of the Ctrl.

But now I have to develop a console application (windows service) without any Ctrl. Is there also a possibility to detect a key?

I found some code in this forum (kbhit() and getch()), but that does not work (as I read still after testing). Would be happy, if you have another solution.

In short form: I have to break a while loop, when user press "x" (for example).

Thank you,

WebChaot

This is highly specific problem IMHO.

AFAIK, windows services that expect user input simply add some gui elements (which reduces it to the former solution).

Hi Mirek!

>>> AFAIK, windows services that expect user input simply add some gui elements (which reduces it to the former solution).

Not really. I want to implement a command line argument "-d" to start the "service" as a stand alone program (for testing and for manual operation). And because its a console application I have no window, but want to break the loop by pressing a key.

Usually the loop runs until the service gets the stop command. For testing mode I have to break the loop otherwise.

Is there no easy solution to do that? If not, I will terminate program in task manager every time, because CTRL-C doesnt work too Smile
