Ascii code problems

You''re probably using a char to read in the value. Try using instead an unsigned char.

Could it be that you''re using a signed char instead of an unsigned char? I think this happens cause as soon as it gets higher than 128 it get''s to the bit that decides if it''s signed or unsigned and that causes the value to be negative...
hope that helped!

and no!, there are NO kangaroos in Austria (I got this questions a few times over in the states ;)

ah, he was faster ;o)

I using a Fstream and a string

Fstream fsInputFile;
string str;
fsInputFile.open("filename.txt",ios:in);

fsInputfile >> str;

can I use this or do I have to switch to usigned char

An fstream is a typedef''d basic_fstream with type char. If instead you use a basic_fstream >, you should be able to get non-negative values for all characters read.

i.e.

You''re using:
typedef basic_fstream > fstream;

try
typedef basic_fstream > my_fstream;
