Problem with string tokenizer
I have the required information saved to "patients.txt" but when i enter the name i want to "search" by the rest of the information should be read from the file and printed to the relevant text fields... i keep getting the exception message ie "Cant open file"... im thinking this is because i have not opened the file correctly?...
ps please ignore the crappy gui
