Cant call up a keyboard with libwiigui

I cant seem to successfully bring up a keyboard using libwiigui, i want the user to enter a url which should then be loaded but OnScreenKeyboard() keeps causing a crash.

char *add = 0;
OnScreenKeyboard(add, 256);
HaltGui();
struct block HTML = downloadfile(add);
ResumeGui();

you still have problems understanding memory pointers, do you ?

use

char add[256];

instead of

char *add = 0;

No i get it now, you dont happen to know whether if its possible to create a button which will append a string to the string on the keyboard.

sure its possible. you probably want to save your string to a global variable and then just create a new button the keyboard to use that string

okay then, hope that will work, i also want to make the keyboard slightly smaller by moving it down slightly and bunching more of the keys together to allow the user to view the content behind
