my problem is:

Code: (Plaintext)
1 2 3 4 5 6 7 8 9 10	gchar uri = "/home/chris/pictures/test.jpg"; gchar result=""; for(gint i=gcharLen(uri)-1;i>=0;i--){ if(uri[i]=='/')break; g_print("#%d %c\n",i,uri[i]); result+=uri[i]; } g_print(result);

what this function is going to return is the name of the file test.jpg
the logic is a little wrong. if it did work it would be backwards.
anyways...
it prints out a bunch of unicode garbage at me.

how can i append characters to result as gchar or string?

The 2 things I would say are first, to allocate memory for the result string (such as using g_new() or g_new0()).

Secondly, the result+=uri[i] seems funny to me. Are you appending a character? You might want to have another variable counting from 0 up and do something like result[j] = uri[i];

If you're trying to get just the filename of a path, try using g_path_get_basename:

Code: (Plaintext)
1 2 3 4	gchar uri = "/home/chris/pictures/test.jpg"; gchar result = g_path_get_basename(uri);

it works.
thank you very much.

i was very suprised to see someone respond to my question.. it doent seem like anyone realy uses this forum. in fact i stop check back here month ago. and one day, after going through old bookmarks, i said 'hey lets see if anyone replyed to my question', and here i am.

so thank you very much.

Note: gchars end in zero. dont forget to put that when your trying something like this.

Code: (Plaintext)
1 2 3 4 5 6	gchar* word[3]; word[0] = 'H' word[1] = 'I' word[2] = 0

np.

Yeah, these forums aren't exactly "catching on" but... who knows. Ain't costing me much to have them up and I'm always here to try and answer a question.

I'm just waiting for them to catch on! I've consistently checked them a few times a week since you announced it on the GTK+ list. I still do the same thing with gnomedev.com as well. I just have problems giving up on things, LOL.
