    alltext = alltext & lineoftext & vbCrLf

    Loop

    TextBox1.Text = alltext

    Catch

    Finally

    FileClose(1)

    End Try

  End If

The code for save will be:

Try

AB.ShowDialog()

TextBox1.Text = AB.PrintToFile

Catch ex As Exception

'Again, do nothing on exception

End Try

The code for Text To Speech will be:

End Try

The code for Back Ground is:

Remember to include hotkeys, you havn't added that. E.g. ctrl-v for paste ctrl-c for copy etc

RE: Text Editor in VB for beginners - AceInfinity - 07-04-2011

Here's my coded example of an advanced notepad that I created around a month ago. Still developing it.

They are all the same thing, just with different modifications, and names. A good list of the features is available through all the posts on the second link. I have encryption, find, tabs, and everything saves to a configuration file that can be loaded from later on "config.ini".

This can be very helpful for beginners, but i wanted to say to whoever is going to use this to learn, try to actually understand the code and not just Copy/Paste..

RE: Text Editor in VB for beginners - AceInfinity - 07-23-2011

If anyone requests a class to read from a configurable ini file, i'll release that later. Completely customized by myself for Setting names and Values, also with a comment or titlespace.

"VB" and "VB.net" are different. You can still do C#, and C++ in VB.
