Working with Fuel FSUIPC

[N402KC]

Hi,

As another feature, I want to create a tool that will get the fuel from the plane, and display the values on a Trackbar. Ive got that done. Now, I want the user to be able to modify the track bar to put how much fuel they want into the plane. So once the user has moved the track bar to the amount of fuel they want in the plane, They press a button that loads the fuel. Anyone know how to do this? Please show examples in either Visual Basic or C#. Thanks
