To use this for variable length records, it is usually necessary to get the record length first.
A thread must acquire the lock before accessing a shared resource. Read Bytes(Rec Size) 'No positionng required ' Process the B array Loop '... The processing for that type of file would involve reading a byte at a time, assembling the byte array, until the Eo R marker is detected. Close() The other possibility is that the records are separated by a record marker.A byte array would actually be preferable to a string if the fixed length string of 28 characters is actually a sequence of 28 bytes that happen to represent ASCII characters – the byte array avoids any issues of encoding and multi-byte characters. Dim Model As String Dim QIS As Double Dim QOO As Double reader.
Let us examine how this works with regard to reading and writing a file from multiple threads.
