Including mmsystem.h - ERRORS

[rickcheney]

Hello,


I'm writing an app that uses the functions defined in mmsystem.h. At the moment its just a skeleton - a Form with a few controls on it but no code yet.

I've started writing a new class CSoundDevice, which again only has a constructor with no code and its only include is mmsystem.h.

When I attempt to build I get hundreds of errors from within mmsystem.h!?

What can I do about this?

Do you have any other include except "mmsystem" ? If not, that might be the reason! Include "vcl.h" before "mmsystem.h" and it should work.

Me again... I assumed C++Builder, but you are obviously not using it. In that case try including both "windows.h" and "windowsx.h"

I am using C++ builder, but the class was not a form so VCL.h was not already included.

It is now though, and it compiles!

Thanks for your help!
