I have a text file which Ineed to read one character at a time, which isn't a problem but on occassion I need to step back to the previous character and read it again. In C I use the seek() function but in vb this doesn't allow negative numbers. can anyone help?

Read every character in your file into array. Then read element by element and keep track of ur current position by a counter. When u need to repeat the previous character under certain condition, just refer to it using the counter. Does it solve ur problem ? or I misunderstood your problem?

This would solve the problem although i'm not sure how it would like to deal with a 12meg txt file, I had thought of something like this and also keeping a variable with the previous character in, i just thought there might be a slicker way of moving within the file. Thanks anyway

There is a seek function in VB and if you use the Get command to read
the next byte you can specify the byte position as the second parameter.
