Can't create a Command Link Button

[magnificence7]

Hi,

I trying to create a command link button (with the CreateWindow function), but I can't seem to use the definition BS_COMMANDLINK and BS_DEFCOMMANDLINK in my code. I DO have these definitions before I include the windows headers:
#define NTDDI_VERSION NTDDI_WIN7
#define _WIN32_WINNT _WIN32_WINNT_WIN7
#define WINVER _WIN32_WINNT_WIN7
Has anyone had a similar problem?

Thank you.
