Win32 equivalent of .net SendKeys

Question

I am designing a system that reads a gesture from Kinect and make some actions. I am trying to include the system to be able to send HotKey to an application. My system is writing in c++ but the UI is in C++.net. I have been able to use SendKeys from the UI part and it does work.

Is there a Win32 equivalent so I can use it in my system?

Thanks in advance!

Answer 1

In WIN32, SendKeys is called SendInput:

It can also simulate mouse movements, etc.

Answer 2

If there are multiple applications, on Vista and higher, UAC integrity levels may prevent applications from sending/receiving Windows messages this way. You may need to call ChangeWindowMessageFilter, ChangeWindowMessageFilterEx functions to enable message-reception in higher elevated process.

Answer 3

The native equivalent is keybd_event
