I actually wanted to have the txt file open up in notepad and have the info by just click a button in my program. private void button3_Click(object sender System.EventArgs e) { FileStream infile = File.Open(binary.dat FileMode.Open); BinaryReader reader = new BinaryReader(infile); FileStream outfile = File.Open(list.txt FileMode.CreateNew); StreamWriter writer = new StreamWriter(outfile); int HMSNRecordNo = Int32.Parse(HMSNIDtextBox.Text); writer.WriteLine(ID# ); string Out; for (int i = 0; i < HMSNNUMBERS_OF_RECORDS; i++) { writer.Write( HMSNRecordNo ); } outfile.Close(); DialogResult r = MessageBox.Show(Open file in Notepad? MessageBoxButtons.OK); if (r.Okay) { System.Diagnostics.Process.Start(notepad.exe list.txt); } }

Looks like you just forgot to close the stream when you were done. fs.Close(). Reading can be done with the StreamReader and reopening the file stream. if you want to read/write while the file is open you can probably just attach your existing file stream to the StreamReader and use it to read. Still you'll need to close the stream ;) -Mike
