Hi,

I am trying to get a touchscreen to work and the calibration program that comes with it is just not working properly. Apparently the calibration points are written into the registry in binary form and I can edit them there. To make this a lot easier I am trying to write a program to read the values and change them to new values. But I have never worked with the registry before. I have looked at a lot of examples on the forums but still am unable to read the values.

Hopefully someone can help me. I need to read these values HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\LowerRightX
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\LowerRightY
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\MiddleX
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\MiddleY
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\ScreenLowerRightX
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\ScreenLowerRightY
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\ScreenUpperLeftX
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\ScreenUpperLeftY
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\UpperLeftX
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\etusbf\Parameters0\UpperLeftY

The values in there are similar to this:- a3 02 00 00 I don't know anything about converting binary so I was hoping to have some code to convert this and show the value in some text boxes. I can then edit the text boxes and write them back to the registry. Any tips on where to start would be greatly appreciated.
