I am try to write a hex viewer, and I am using the following to get the data in from the file.
String mfileinfo = LoadFile(fs);
Then I am using
thebyte = mfileinfo[i];
Where i just counts through 1 byte at a time the data on the file.
I have tried with thebyte being defined as int unsigned, int, and char, and when it encounters a hex byte of C3 in the input file it gives the value as -61, also when it comes to a C8 it gives a -56 as the value for thebyte.
When C3 should return 195, and the C8 should return 200.
Why am I getting the what I think is the wrong value for those bytes? How do I get it to return the correct value?
Is this a BUG, problem with LoadFile? Should I use some other way to load the data into the program?
Thanks
David

Well, I know pretty sure LoadFile works. Means it is something else, but hard to say on so little info.
Anyway, (char)-61 is 0xc3, so the most likely reason is that you put data into 'char'....
