[RESOLVED] Spelling Checking

I'm trying to code a spelling checker into VB.NET 2010.
It'll check the RichTextBoxFindandPrint (my version of RTB) control.
However the solutions on the internet require Word to be installed.
Any non-Word ideas?

PS. I found .NetSpell, how to code it in?
http://www.codeproject.com/KB/string/netspell.aspx

Having no idea what NetChecker was, I googled it, and found that it is a "NetChecker is a network diagnostic & assistance tool designed to simplify your everyday tasks."

What does that have to do with spell checking a richtextbox?

*facepalm*
It's .NetSpell

Ok...never heard of that either, but Google did a good job.

According to this, you don't need any kind of coding.

http://www.aspnetspell.com/?gclid=CL...FYa7Kgod2zVanQ

it said multiline textbox not richtextbox

and it said ASP.Net Web Applications not VB.Net Desktop Applications

:confused: This is exactly what is says

Well then I need either the source or a different solution because if I use this I'll lose my other richtextbox which has the extended ability to print and find stuff.

So you tried it with your control and it did not work? Maybe you could extend the control in the same way that you extended the RTB?

Is this:

The same .netspell your on about? If so i use this library on my rtb's and i cant praise it enough, no need to have word etc installed, and its easy to code for, ill post up some cod eif this is the same library.

OK... I'll post my RichTextBoxPrintandFind code tomorrow

Any way to put .netspell inside this code?

Please help me!

I'll do anything for spell checking in my program!

Did you read this:

"Using the Library

To use the NetSpell Library in your project you simply add a reference to NetSpell.SpellChecker.dll to the project. You can also add the library to the Visual Studio Toolbox to make it easier to interact with the properties. The library is event based so you have to handle the various events. Also, if you set the ShowDialog property to true, the library will use its internal suggestion form to display the suggestion when a MisspelledWord event occurs.

The following code is a very simple implementation of the NetSpell library..."

It seems straight forward. Have you downloaded it? Did you add a reference? What have you tried?

I'm a noob, help me...
Right, I'm downloading .netSpell
I got a million files now.
I dragged it in the toolbox, Spelling and WordDictionary appeared.
What's next?

Do what I would do if I were attempting this, which I have never done, read the directions on the link. C# isn't that far from VB.

I know only VB

There are quite a few free online C# to VB.NET converters out there, like this one, that do a pretty good job.

Don't expect anybody to simply write out the code for you, because that usually won't happen. Everybody on this forum is a volunteer and generally if they have to spend more than a few minutes to write the code for you, then they won't.

Thanks, I'll try it

Heres how i use this dll, obviously you will have to adapt the code to suit your needs, i have an RTB and a button whcih when clicked performs the spellcheck.

Heres how the code is:

vb Code:

Private Sub SpellChecker2_DeletedWord(ByVal sender As Object, ByVal e As NetSpell.SpellChecker.SpellingEventArgs) Handles SpellChecker.DeletedWord
        'save existing selecting
        Dim start As Integer = RichTextBox8.SelectionStart
        Dim length As Integer = RichTextBox8.SelectionLength
 
        'select word for this event
        RichTextBox8.Select(e.TextIndex, e.Word.Length)
 
        'delete word
        RichTextBox8.SelectedText = ""
 
        If ((start + length) > RichTextBox8.Text.Length) Then
            length = 0
        End If
 
        'restore selection
        RichTextBox8.Select(start, length)
 
    End Sub
 
    ' Handles replacing a word from spell checking
    Private Sub SpellChecker2_ReplacedWord(ByVal sender As Object, ByVal e As NetSpell.SpellChecker.ReplaceWordEventArgs) Handles SpellChecker.ReplacedWord
        'save existing selecting
        Dim start As Integer = RichTextBox8.SelectionStart
        Dim length As Integer = RichTextBox8.SelectionLength
 
        'select word for this event
        RichTextBox8.Select(e.TextIndex, e.Word.Length)
 
        'replace word
        RichTextBox8.SelectedText = e.ReplacementWord
 
        If ((start + length) > RichTextBox8.Text.Length) Then
            length = 0
        End If
 
        'restore selection
        RichTextBox8.Select(start, length)
    End Sub

The above 2 just need placing in and the 'richtextbox8' replacing with your rtb.

And then on the button used to trigger the spell check this code:

vb Code:

SpellChecker.Text = RichTextBox8.Text
        SpellChecker.SpellCheck()

Reply to post #18

so I got - line 1 col 10: invalid TypeDecl
And no source.

The world is a incompatible place.

We are getting close! SpellChecker is not declared. It may be inaccessible due to its protection level.

Did you mean something else?

I've got:
Spelling1
WordDictionary1

vb Code:

Private Sub SpellChecker1_DeletedWord(ByVal sender As Object, ByVal e As NetSpell.SpellChecker.SpellingEventArgs) Handles SpellChecker1.DeletedWord
        'save existing selecting
        Dim start As Integer = Rich.SelectionStart
        Dim length As Integer = Rich.SelectionLength
 
        'select word for this event
        Rich.Select(e.TextIndex, e.Word.Length)
 
        'delete word
        Rich.SelectedText = ""
 
        If ((start + length) > Rich.Text.Length) Then
            length = 0
        End If
 
        'restore selection
        Rich.Select(start, length)
 
    End Sub
 
    ' Handles replacing a word from spell checking
    Private Sub SpellChecker1_ReplacedWord(ByVal sender As Object, ByVal e As NetSpell.SpellChecker.ReplaceWordEventArgs) Handles SpellChecker1.ReplacedWord
        'save existing selecting
        Dim start As Integer = Rich.SelectionStart
        Dim length As Integer = Rich.SelectionLength
 
        'select word for this event
        Rich.Select(e.TextIndex, e.Word.Length)
 
        'replace word
        Rich.SelectedText = e.ReplacementWord
 
        If ((start + length) > Rich.Text.Length) Then
            length = 0
        End If
 
        'restore selection
        Rich.Select(start, length)
    End Sub
 
    Private Sub Button1_Click_2(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        SpellChecker1.Text = Rich.Text
        SpellChecker1.SpellCheck()
    End Sub

That's my current code, no en-GB.dic found.

How does

vb Code:

internal System.Windows.Forms.RichTextBox Document;
internal NetSpell.SpellChecker.Spelling SpellChecker;

translate to VB.NET?

You need to put the en-gb.dic inside your debug/projects exe folder.
