Hello there! Welcome to the FBI watch list, enjoy your stay!

Thank you so much the effort in this video was amazing I understood every function you put into this video. Thanks!

[canopyjunkie]

thanks man, not a lot of info on stack about capturing inputs, this gives me a good head start on a project that doesn't need to record input, but instead just tell me if there was any within the last 60 seconds.

Well I'm not using this as a key logger, I plan on using this as a screen overlay for the OBS application. I was able to convert this to a windows form application and update a label. The Alt key does not register and I was wondering if you have a way to capture which mouse button was pressed or a way to capture scroll wheel input? This was very informative and a good way for me to get back into c#. Thanks
