Please don't post in HTML format.

You have called allegro_init() before creating engine, havn't you? Put it in
the constructor for engine if engine is a global, otherwise call it
beforehand.

Subject: Small Allegro Problem


Hi, I made an small program that goes in graphic mode.  It works great
actually, but the problem is that I want the user to know if the text to
graphic change was successful.  Here is the code that I used.  It doesn't
bug the program, it just goes in a black screen (in text) when I change my
gfx_driver to ATI for example (which I don' t have).  But in auto_detect it
works fine.
res_x = 800
res_y = 600
color_depth = 15
short engine::init_graphics(ushort res_x, ushort res_y, ushort color_depth)
{ 
cout << "Loading Graphic system at " << res_x << "x" << res_y << "x" << color_depth << "bits...\n"; 
clear_keybuf(); 
fade_out(1); 
set_color_depth(color_depth); 
short int g_result = set_gfx_mode(GFX_ATI, res_x, res_y, 0, 0); // *** TO CAUSE THE ERROR, WORS IN AUTO_DETECT 
if (g_result < 0) 
   { 
   stop(1); 
   textcolor(LIGHTRED); 
   cprintf("Error, graphic initialisation failed...Aborting...\n\r"); 
   cprintf("Possible error(s):\n\r"); 
   textcolor(WHITE); 
   cprintf("%s", allegro_error); 
   exit(1); 
   } 
else cout << endl; 
return g_result; 
} 
void engine::stop(ushort error_num) 
{ 
allegro_exit(); 
clrscr(); 
textcolor(WHITE); 
textbackground(RED); 
cprintf("Stoping Omega Engine                                                            "); 
normvideo(); 
cout << "All systems unloaded..." << error_num << " errors.\n\n"; 
textcolor(WHITE); 
} 
Thanks, Nicolas Blais
