Thanks for your help, Victor!
I try to use VS6.0 with SP6, it work ok when I open other project but with NetXMS is not. No error message when open NetXMS.dsw but it don't work.
When I create empty workspace then insert project (nxhttp.dsp) into it,
and if compile project, it generate error:
NMAKE : fatal error U1052: file 'nxhttpd.mak' not found
Stop.
Error executing NMAKE.
Sorry for my english!
Thanks!
