Can't declare EXTENSIONS

Hi, nice day

I can’t declare extensions… default OPENGL 1.1 works such as glLoadIdentity :

WINGDIAPI void APIENTRY glLoadIdentity (void);

Okay, so “glLoadIdentity” is the ENTRY in “Opengl32.dll”, that’s simple okay ?

'typedef void (APIENTRY * PFNGLACTIVETEXTUREARBPROC) (GLenum target);

That doesn’t work !!! Neither I can declare the entry “glActiveTextureARB” or neither
“PFNGLACTIVETEXTUREARBPROC” works !!!

*** Please help ***
