Hello guys

I am having trouble displaying my tooltip windows in VS2005 compiled projects (32bit option on a 64bit system).
They used work when compiled with VC6 on 32bit machines.

I am creating a window of TOOLTIP_CLASS in CWnd::OnCreate() of the owning window
and using it with messages TTM_UPDATETIPTEXT, TTM_TRACKPOSITION, TTM_TRACKACTIVATE messages whenever I wish to show them.

Cheers,
Sebastian

Define the following in your header file
#define WINVER 0x0500 or lower
#define _WIN32_WINDOWS 0x0500 or lower
#define _WIN32_WINNT 0x0500 or lower

By default the definitions vary based on target OS.
Mapping is here

Hi

OK, these macros had defaulted to Windows Server 2003 in my builds.

So, I cannot define WINVER for Windows XP or higher ?
I will be trying it out - in the meantime: What are the consequence for my tooltips based on these macros.

Cheers,
Sebastian

I think there won't be any consequence as the tooltips would work correctly for the specific OS. You can also refer to this article.
