Getting a filename from a file, then opening....

here it is in more context so you can see what it looks like and get a better feel for what im doing. in the file it has c:\games\textures\clouds.bmp listed as a texture for an object. that''s what im trying to get out and load.

sorry for the double post, the first one screwed up and put that link in too because i used a between brackets. i changed it to 'd'

fname[fnamelength] = ''\0'';
this should be
fname[fnamelength-1] = 0;
Remember, as the string starts at 0 it ends at (length-1). Writing to fname[fnamelength] is touching memory that you shouldnt be, though in this case it probably isn''t touching anything critical, and I doubt that it''s what is causing the problem. My next debugging suggestion would be to try running OpenTexture("whatever.bmp") instead of passing the char pointer, and see if that works.
Good luck

the filename thing was correct because of how i set it up, but that second part led me to fix the problem. THANKS!!!
