SO you can see that the problem is in the str[i];

i wonder why ! I've tried to cast it to (const char *) but it didn't work. so any idea's ?

Oh and i know i didn't use ARRAY_SIZE i'm using it later

[bobdark]

Thats because str[i] is a character. What exactly are you trying to do there? Im asking because I didn't really read your code, its a type problem. If you want to pass the part of the string starting at index i - you should call

strcpy(temp, &str[i]);

or

strcpy(temp, str+i); 

, don' know what's more readable.

[Moudi]

The point of this program is to :
1 Read the input from first texbox
2- pass it to a string and take every character and colorize it with BB codes and save every step in temp.
3- print it in second texbox.

Well with the code you supplied it doesn't crash anymore, but the output is chinese stuff

Guys i finished it, i can't believe how happy i am D:

All i need to do is work out a dynamic rand ...

[dargueta]

Your problem probably comes from using a char array when you should be using a wchar_t array. If you notice, you typecast temp as a LPCWSTR which stands for Long Pointer to Constant Wide-character STRing.This means you need to declare str and temp as arrays of wchar_t instead of char, and use the wide-character string functions wcscmp, wcscpy, and so on. Look here for more information about wide-character stuff.

EDIT: Oops - wrong and late. Well, I tried. In any case, I do think you should be using the wchar_t stuff because-- I think--things could go wrong with a char array if you're not careful. Although, if you're using the TEXT() macro then you should be using the TCHAR functions instead. Technically more correct, but I guess it's not necessary? Just my two cents.

[Moudi]

heheheh thanks anyway mate :)

[dargueta]

Not doing my reputation any good... :D

[Moudi]

You must spread some Reputation around before giving it to dargueta again.

Don't worry i already repped you like 2 days ago :P

Thanks!
