I am having problem catching the ALLEGRO_MESSAGEBOX_YES_NO return value. Here is the code i have made. 1int resize = ALLEGRO_MESSAGEBOX_YES_NO;
2
3 int box = al_show_native_message_box(display, "Change display", "Are you sure?",
4 "Do you want to change your display to 600x600?", "Of course|No", resize);
5
6 if(resize == 1)
7 {
8 al_resize_display(display, 600, 600);
9 }

Your 'display' pointer is bad, but you didn't get this error before because ALLEGRO_MESSAGEBOX_YES_NO isn't equal to 1, so the al_resize_display() was never called. They all watch too much MSNBC... they get ideas. |

I got it to work, but i get a weird thing in the display Edit: I didnt get this error with your code {"name":"606488","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/e\/e\/ee68b60bdb4ade90c9d5119dd2d2d1b9.png","w":301,"h":394,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/e\/e\/ee68b60bdb4ade90c9d5119dd2d2d1b9"} www.anothergames.com |

I edited my previous post just when you were posting. Save your code to something else temporarily and try what I posted. It worked OK for me except the window always went to lower right corner of desktop, whether the al_set_new_window_position() was above the resize or not.

Very weird errors indeed. I will try to find what is the problem with the programs. Also, when executing your code, it shows in the center of my screen, so it works perfect! Still, i cannot understand why i get that white think EDIT: i got it to work, but i used 2 times the al_flip_display(); Here is my code 1#include <allegro5\allegro.h>
2#include <allegro5\allegro_native_dialog.h>
3
4int main (void)
5{
6 al_init();
7
8 ALLEGRO_DISPLAY *window = al_create_display(200, 300);
9
10 al_flip_display(); // First time!
11
12 int resize = al_show_native_message_box(window, "Change display", "Are you sure?",
13 "Do you want to change your display to 600x600?", "Of course|No", ALLEGRO_MESSAGEBOX_YES_NO);
14
15 if(resize == 1)
16 {
17 al_resize_display(window, 600, 600);
18 al_flip_display(); // Second time!
19 }
20
21 al_rest(3.0);
22
23 al_destroy_display(window);
24}
Actually, i was thinking if the user, can specify himself the resolution using a text box, or maybe two. Is it possible? www.anothergames.com |
