Yes, you can. In case you decide to use d3d as well, in addition to DirectPlay, consider this (quoted from the DX SDK):

Quote:
Compilers from Borland report floating-point exceptions in a manner that is incompatible with Direct3D. To solve this problem, include a _matherr exception handler like the following:

// Borland floating point initialization #include <math.h>#include <float.h>void initfp(void){    // Disable floating point exceptions    _control87(MCW_EM,MCW_EM);}int _matherr(struct _exception  *e){    e;               // Dummy reference to catch the warning    return 1;        // Error has been handled}

EDIT: Sorry for polluting the OpenGL board with DX stuff [smile]

Having said that, winsock and other networking libraries should work fine also - I don't really see a problem with Borland not supporting networking!
