Adding spell check to textboxes in Winform app

Question

I am trying to add spell checking to text boxes in my Windows Forms app. I am using Visual Studio 2015, the .net framework 4.5.2, a Windows Forms project and visual basic. System.Windows.Controls is supposed to have a SpellCheck function but System.Windows.Controls isn't even available to me. It does not show up in intellisense either. Anyone know why?

Thank You! - Andy

I am trying to add spell checking to text boxes in my Windows Forms app.

System.Windows.Controls exists in the WPF namespace. If this is a WPF project then you should ask in the WPF forum. You can implement spell checking in a windows forms text box by hosting the WPF component. See:

Hello Andy,

It's only available for WPF project/apps.

Please remember to mark the replies as answers if they help and unmark them if they provide no help, this will help others who are looking for solutions to the same or similar problem. Contact via my Twitter (Karen Payne) or Facebook (Karen Payne) via my MSDN profile but will not answer coding question on either.

I located a custom TextBox that does this created in C#. You add the ExtendedTextBox project to your Visual Studio solution, build the project and the new control will appear at the top of your toolbox. Add one to your form, build and then try it by misspelling a word.

The original code where the solution was messed up and I fixed it and placed it on my One Drive.

My simple demo with zero code.

Please see this thread Spell checking a plain TextBox as hosting a WPF TextBox in a Windows Forms app is pretty simple.

I've created a VB.Net 2010 Class as a wrapper for a WPF TextBox control. The class project (.sln) is added to your WinForms project and then the control shows up in the toolbox. I've zipped it into a compressed folder but see no way to attach it here......

There is no provision for attachments in the forum. To share, use (say) One Drive and post the link in the forum.

I know this is an old thread, but hoping its still got some life.

Nice little demo, thanks for that but how would I get the events to fire?

e.g. KeyPress and many other events don't fire.

Thanks

Sam
