Selecting combo box items

[Honski]

I'm trying to figure out how to click combo box elements using the old d3adventure c# base. Currently I'm calculating the y/x coordinates in a very bad way and just send a mouse click to that position, but it's a lot of work and requires changes for every combo box.

Is there a way to get the current x/y coordinates of ui elements?
DarthTron's framework uses a global click function for all ui elements if I got the source right. Any way to easily implement that into a c# project?

UI Elements have a size and position
UiElement+0x508 is where it starts
Read as floats
left=0x508
top=0x50c
right=0x510
bottom=0x514
