CListCtrl methods do not existing (Grouping)

[MikeB]

I wanted to add grouping to my CListCtrl and according to MSDN, CListCtrl has an InsertGroup(...) method. When I try to use this method, intellisense is not showing it and if I try to use it anyway I am told by the compiler that the method does not exist.

I am using Visual Studio 2010 with the platform toolset v90 and MFC in a shared dll. Not sure what other information I can procide, but, why do I not have this functionality?

Any offers of assistance?

If you look at its definition in the header file you'll see this before it.

#if (_WIN32_WINNT >= 0x0501)

Yeah, I found that. Not on the header but somewhere on the net. I have it working.

Thanks
