How are the WM_Touch messages sent to windows ?

May 9, 2012 at 5:41 PM

Hi , 

Great Work, It seems very interesting :) . 

I am trying to understand how are the wm_touch messages sent to windows , from what i read what we have to do is call sendmessage() or Postmessage() , but i cannot find a call to sendmessage or postmessage in the source code of MTV . 

I will be very glad if you can explain me about how it is done ?

MTV does not generate WM_TOUCH messages. Actualy generating WM_TOCH events manually is not recomended at all. MTV works as any real multitouch device. It sends touch data through the driver to Windows 7. Then Windows generates all messages as it needs them.

Ohk , Thanks for such a prompt reply :) . 

How does the driver sends the touch data to windows 7 and in what format ? Is the code included in the project, i tried to have a look at Multitouch.Driver source code but it was difficult to understand . It will be very helpful if you could give me some pointers on where to start .

According to license you can use UniSoftHID only together with MTV. Why do you want to communicate with the driver directly?

I want to develop my own driver.Therefore , i wanted to know how to send touch data to windows 7 . 

If this is not possible due to the license of this driver , then ohk . Thanks Anyways .
