NSIS Function to get main display refresh rate?

[enzeinzen]

Hi' i'm trying to include a function in my script to detect the refresh rate of the main display. However, I do not know how to incorporate the functions into NSIS code.

I already managed to find a way to get the resolution using the following code:

System::Call user32::GetSystemMetrics(i0)i.r0
System::Call user32::GetSystemMetrics(i1)i.r1

However, in order to obtain the refresh rate, one must use EnumDisplayDevices to get the right display and then pass that to EnumDisplaySettings. I do not know how to do that.

Any help would be much appreciated. I am trying to build a portable application using the portableapps.com framework that uses NSIS language.

Thank you and sorry for being a n00b.
