     SaveFileDialog1.Filter = "bin files{*.bin)|*.bin"
     If SaveFileDialog1.ShowDialog = System.Windows.Forms.DialogResult.OK _
     Then
         My.Computer.FileSystem.WriteAllText _
         (SaveFileDialog1.FileName, TextBox7.Text, True)

What kind of content you want to store in that binary file. Seems, you want to store text. Changing the file extension does not change the type of file. Got it?
You have to be more specific and provide more details, about your issue.

I want to open .bin, that bin contains 512 bytes with "1 byte space 1 byte space" pattern. You can see on that image http://imgur.com/a/C2lZc

Solution 1

Use a BinaryReader Class (System.IO)[^] to read the file. You will then need to do whatever processing is necessary to make the binary data into readable text which you then put in the textbox.
