Hello,

for industrial use, we want to connect 2 additional mouse. The position of the mouse data to be evaluated in a separate application. My problem is that is indeed such a mouse automatically logs on to Windows and then move the mouse pointer of course. This I will not.
Could hear the supplied mouse I recognize on the basis of VendorId. But I have no idea how I can suppress the assignment in Windows and get to the mouse data.
Has anyone of you an idea ?

Thank you very much

Mike

Hello,

Microsoft has an SDK for handling multiple mice. Using the SDK you can get input from up to 25 different mice.
This SDK comes with a comprehensive set of examples.

http://www.microsoft.com/multipoint/mouse-sdk/default.aspx[^]

you start by assigning a MultipointMouse event:

C#

MultipointMouseEvents.AddMultipointMouseDownHandler(this, this.OnMultipointMouseDown);

and in the event handler you deal with the mouse data:

C#

private void OnMultipointMouseDown(object sender, RoutedEventArgs e)
{
    var args = (MultipointMouseEventArgs)e;
}

you can access the device that sent the event:

C#

args.DeviceInfo

You can know the state of the buttons:

C#

if (args.Buttons == RawMouseButtons.LeftDown)
{
    //do something...
}

Etc... Etc...

The SDK comes with a few easy c# samples.

Valery.
