Occasionally we add in functions for a customer as a one off that do not get published but could be of use to other users.  This document lists such functions.

Edge Acceleration

Cursor accelerates towards the edge of the screen when stylus moves towards the edge. Set the following registry settings using Regedit to invoke the function

Registry branch =[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TBUPDD\Parameters\{guid}\1]

The guid is a long number generated by the UPDD build process


"Top Edge Gain"=dword:00000014 (20)

“Top Edge Width”=dword:00000f00 (3840)

 

"Bottom Edge Gain"=dword:00000014 (20)

“Bottom Edge Widtht”=dword:00000f00 (3840)

 

"Left Edge Gain"=dword:00000014 (20)

"Left Edge Width"=dword:00000aaa (2730)

 

"Right Edge Gain"=dword:00000014 (20)

"Right Edge Width"=dword:00000aaa (2730)

 

Edges not defined or set to 0 do not have acceleration.

 

The Height and Width setting is based on a 65535 x 65535 logical desktop area.  The gain value is the movement accelerator.  The values suggested were set during testing with reasonable results.  Only works for primary monitor.

 

For convenience, place the following in a .reg file (say ea.reg) and double click on the reg file to place the settings in the registry: (remember to change the guid to that shown in the registry)

 

Windows Registry Editor Version 5.00

 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TBUPDD\Parameters\{guid}\1]
