Active Oldest Votes. MarkJ MarkJ I'm reading a decompressed pdf file and getting error "Input past end of file" on the InputB line — Shodan. I converted it into a function as suggested by Shodan — MarkJ. Shodan that "Input past end of file" error is odd. What is LOF returning? It should be the length of the file in bytes. And then InputB is expecting to be passed the number of bytes to read, so it's hard to see how it can read past the end of the file.

IO namespace. The basic file-handling commands had not changed; just a few more features had been added. With Visual Basic. NET, Microsoft introduced a new, object-oriented method for working with files. The System. IO namespace in the.

NET framework provides several classes for working with text files, binary files, directories, and byte streams.

I will look specifically at working with text files using classes from the System. Basic methods Before we jump into working with text files, we need to create a new file or open an existing one.

That requires the System. File class. This class contains methods for many common file operations, including copying, deleting, file attribute manipulation, and file existence. For our text file work, we will use the CreateText and OpenText methods. StreamWriter object. With the StreamWriter object, you can then write to the file. The following code demonstrates how to create a text file: Dim oFile as System. File Dim oWrite as System. StreamReader object.

With the StreamReader object, you can then read the file. File Dim oRead as System. StreamWriter class for writing to the text file are Write and WriteLine. The difference between these methods is that the WriteLine method appends a newline character at the end of the line while the Write method does not. Both of these methods are overloaded to write various data types and to write formatted text to the file.
