How do I use a hotkey to hide and show my winForm?

I want to create a winForm app that contains text in the window. When I start up my winForm app, I want to see the window and then press a hotkey to hide the window.

Then press the same hotkey again to display the window again. So I can toggle the window with one hotkey to show and hide itself.

I'm not sure how to go about doing this.

I'm using vs 2010 C++ and a winForm app.

Thanks for any help and comments.

This article explains how to do it: A Simple C# Global Low Level Keyboard Hook[^]

You need a keyboard hook to restore the window ...

The following two articles demonstrates how you can integrate native C++ code and managed code:
Using ACE with C++ CLI[^]

Integrating ACE and ATL[^]

Develop your Windows Forms stuff using C#, C++/CLI, or any other language supporting the CLR.

Info about creating native keyboard hooks:

KeyBoard Hooks[^]

Personally I prefer to do managed stuff in C# - and use P/Invoke, C++/CLI or COM to access native functionality.

Solution 2

I'm using vs 2010 which supports only C++. vs 2012 and vs 2013 no longer support creating WinForm apps in C++. My app needs to hook into another commercial application's SDK and requires C++ to interface.

Thank you for the reference but I need an example or examples in C++. I'm not very experienced with C# or C++ so trying to convert it over to C++ would be a challenge for me.

Thank you...

Consider using C++/CLI to create a .Net integration layer for use with the commercial application's SDK. Then you'll be free to use any CLR language you want to create the actual UI.
