Finally I can use the wanda buttons in my code
. Just for the benefit of others I would share the solution that worked for me.
As pointed out on this thread earlier by Farshizzo that wanda is plug and play device, somehow it was not acting that way for me. I mean, wanda was not acting as mouse. To make it as a mouse I made some registry settings.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\sermouse and change the value of start = 3.
Rebooting the computer is required after this.
After this all the mouse callbacks in Vizard can be used for wanda device also.
However, after this change trackd doesn't work properly. So, to make it work the same registry variable stated above should be set to 4.
Thanks for all the help.
