      Have you checked if the vendor provides a library to access touch screen functionalities?

      cpallini's correct... this type of information would only come from software provided by the vendor and will be vendor specific... meaning one vendor's libraries or API calls will not work with anothers

          Touch screen devices usually report the touch pressure.

          Wrong. If you can provide an API link on MSDN to support your theory, I'll be happy to read it. The need for applying "pressure" comes from using a touch screen that is based on resistive touch technology. In this case, the pressure applied will bring two different electrical layers together at one point, and when they touch, there's a change in the electrical current there, which is registered as a "touch". No matter how hard or gently you touch, the event is going to be either touched, or not. There's no way to measure the pressure. If I were to use a capacitative touch screen, it works based on the weak electric signals emitted from the skin. Now, where is the pressure on that?

            Well, that's the same thing I said as well in my reply to the OP. And, that would be the only possibility. :) If a device is sensitive to such data, and is exposing APIs to capture that information, then that would be a different story. However, it is not the case with regular mouse and touch pad devices.

              Pressure is computed, see, for instance http://www.analog.com/static/imported-files/data_sheets/AD7877.pdf[^], "TOUCH-PRESSURE MEASUREMENT" section. :)

                That is for devices manufactured by a certain company. I indicated in my first post that such things are possible if the manufacturer has implemented such a feature and is exposing APIs to capture those details. However, that would be an edge case. But most devices are simpler, and Windows certainly does not provide you features to measure "touch pressure". Again, I'll ONLY accept an API from MSDN that tells me what the touch pressure was when a touch event happens. :)

                                  :) I usually do what I want, anyway. I suppose my managers are not so happy... :rolleyes:

                                    Sorry for my misunderstanding (read error) :laugh:. You mean touch pressure strength or, I think, sometimes called pressure size. I'm not sure that this is standard information beside location information reported by device. This theoretically possible feature may not be carried out by all manufacturers.

                                    Thank for your reply. I had notice that Photoshop can get the pressure strength from some touch pad. So I try to find which way Adobe used to implement it. But I found nothing. I guess that is a standard of Adobe. So I will try to develop my application by the API provided from vendor. Thanks again! :)
