File Handling - Difference between VB 6.0 and VB .NET???

[Lily]

How do you open a sequential file using OpenFile Dialog and read from it in .NET?
Also, how do you create an open file, write to it, and save it using SaveFileDialog in .NET?

I was trained using 6.0 and am unable to make the conversion to .NET.

The OpenFileDialog and SaveFileDialog don't do any of the read/writing
to/from files. All it does is give you a new UI to let the user select
the name of the file. On the OpenFileDialog object you do something like:

Dim OFD as new OpenFileDialog
OFD.ShowDialog( )
MessageBox.Show (OFD.Filename)

Then you will use the FileName method open your file for reading.

Look at the StreamReader/StreamWriter class to see how to read/write
from files.

Good Luck

Lily or Jody or whatever

In addition to Chris, if you got the file, than in the streamreader and
streamwriter classes on MSDN are (in a table) links to a lot of samples
given how to handle your problem.

Although it is possible, do I never the classic VB6 file handling methods
because they are less descritive.

I hope this helps
