I need to determine if a slider within a separate application is enabled or disabled programmatically.
Same thing with a progress bar.

Do you have access to the other application's window handle?

you mean handle to other applications main window, right ? If yes then there seems to be a need of enumerating all the child windows of main window and then perhaps children of children until you get to the slider window.

once you have found hWndslider you can use IsWindowEnabled(hWndSlider) to determine if it is enabled or not.

I suggest you use spy++ and determine the window hierarchy for that application, that may give you some hint about where you are going to find that slider.

This way you can use FindWindowEx to get to the slider, otherwise using EnumChildWindows might be a little extra work.

And when you have the handle of the slider, use the IsWindowEnabled() API.
