If you have ever used Microsoft Word then you know that it has a good spell checker and it may have occurred to you that the ability to check spelling might be a nice piece of functionality to add to certain applications of yours. Well the code that follows allows you to easily do just that.

A few things to note about the code.

o Microsoft Word must be installed on your PC and on any of your users' PCs in order for this code to work
o No Reference to Word is required in your application
o The code as shown will check spelling but you can also have it check grammar by changing the objDoc.CheckSpelling line  to objDoc.CheckGrammar
o You can replace the textbox with a RichTextbox if you like and the code will work with it as well
o In Excel you will need to remove the App.OleRequestPendingTimeout = 999999 line
o The code expects an ActiveX textbox named "Text1" and an ActiveX command button named "SpellCheck"

Private Sub SpellCheck_Click()
                          Dim objWord As Object
                          Dim objDoc  As Object
                          Dim strResult As String
                          Const QUOTE = """"
                          On Error GoTo ErrorRoutine
                          App.OleRequestPendingTimeout = 999999
                          Set objWord = GetObject("Word.Application")
                          If TypeName(objWord) <> "Nothing" Then
                              ' Word is already open
                              Set objWord = GetObject(, "Word.Application")
                              ' Create an instance of Word

                                  Set objDoc = objWord.Documents.Add
                              Case Else
                                  MsgBox "Sorry but your version of Word seems to be " & QUOTE & objWord.version _

                          objWord.Visible = False

                          Text1.Text = strResult

The following is a picture of the code in action. (Talking about 'action', the desktop picture behind the spell checker is me being tossed out of a boat while white water river rafting:) )

When the code is run, misspelled words are colored red and so after I clicked the 'Spell Check' button the word "nicly" was highlighetd in be red by Word.

For Office 365 apps, you will need to adjust line 22 to add 16.0 as such:

Case "9.0", "10.0", "11.0", "14.0", "15.0" , "16.0"
