ShObjIdl location for JNA usage

[Matteo Migliarini]

I'm trying to use shobjidl_core.h library to run code that changes the wallpaper of one specific monitor, specifically I need to run these two functions: GetMonitorDevicePathAt, SetWallpaper.

Now, when I run the following code:

interface shobjidl_core extends Library {
test.shobjidl_core INSTANCE = Native.load( "ShObjIdl.idl", shobjidl_core.class);

void GetMonitorDevicePathAt(int monitorIndex, WString m);
void SetWallpaper(WString monitorId, WString wallpaperPath);
}

I've tried any variation of "shobjidl" but still I can't find one that works. From what I understood about JNA it needs a dll containing the library, but I can't find any dll related to shobjidl

What should I do to load shobjidl?

Hi Matteo,

You are looking for the COM bindings of IDesktopWallpaper. This is not
a classic library you are loading.

Please have a look here:

In the project IDesktopWallpaper I added a minimal sample, that
demonstrates how the library can be loaded and used.

Thanks a lot!! Now it works! Can I use your code in my project as long as it is under MIT license right?
