GETMONITORINFOEX struct not generated

[JesseAtExitNorth]

My NativeMethods.txt is simply User32.* and while the GETMONITORINFO struct is available (https://docs.microsoft.com/en-us/windows/win32/api/winuser/ns-winuser-monitorinfo) GETMONITORINFOEX wasn't generated.

I'm not sure if I am doing something incorrectly or this is a bug.

There is no GETMONITORINFO struct, nor GETMONITORINFOEX. I think you meant MONITORINFOEX (no GET in front).
Structs aren't exported from User32 or any other module. They are simply in header files. We autogenerate structs when you ask for a method based on the method signature. You get MONITORINFO because that is used in the method signature, but MONITORINFOEX is not.

To get MONITORINFOEX, you will need to ask for it explicitly in the NativeMethods.txt file.

@AArnott Could the generator detect this kind of situation and provide a helpful error telling you what your options are?

Filed an issue to track

Ah, the reason for that is that MONITORINFOEX does not exist in the metadata. It varies between unicode and ansi versions so you have to request MONITORINFOEXW or MONITORINFOEXA.

Thank you!

So if I add MONITORINFOEXW or MONITORINFOEXA to NativeMethods.txt those types do get generated, but I still can't call GetMonitorInfo though since it still generates with the MONITORINFO parameter which isn't a superclass of the EX types.

[AArnott]

MONITORINFO* types are structs, so they cannot be super-classes. Just like in C, you can allocate an EX struct, initialize its cbSize field, then pass a pointer to it to the GetMonitorInfo method, and it'll determine based on cbSize that you gave it the Ex struct and initialize its additional fields.
