How do I get the trackbar value?

Question

I feel a little silly asking this, seems pretty simple but I can't find the solution anywhere. I have a trackbar made in visual studio 2008 and I want to use it to adjust an image threshold but I can't find the code to retrieve the sliders/markers position. Any help would be much appreciated and I am using C++

For raw Win32, send the trackbar a TBM_GETPOS message.
