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
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 objWord = CreateObject("Word.Application")
Select Case objWord.version
'Office 2000 and later
Case "9.0", "10.0", "11.0", "14.0", "15.0"
Set objDoc = objWord.Documents.Add(, , 1, True)
Set objDoc = objWord.Documents.Add
MsgBox "Sorry but your version of Word seems to be " & QUOTE & objWord.version _
& QUOTE & " and that version is not currently supported.", vbOKOnly + vbExclamation, "Spelling Checker"
objDoc.Content = Text1.Text
objWord.Visible = False
strResult = Left(objDoc.Content, Len(objDoc.Content) - 1)
' Reformat carriage returns
strResult = Replace(strResult, Chr(13), Chr(13) & Chr(10))
If Text1.Text = strResult Then
' There were no errors, so give the user a
' visual signal that something happened
MsgBox "No changes made", vbInformation + vbOKOnly, "Spelling Checker"
Set objDoc = Nothing
Set objWord = Nothing
' Replace the selected text with the corrected text. It's important that
' this be done after the "Clean Up" because otherwise there are problems
' with the screen not repainting
Text1.Text = strResult
Select Case Err.Number
' There's no instance of Word so continue processing in order to create one
MsgBox "Word must be installed in order for this code to work", vbCritical + vbOKOnly, "Spelling Checker"
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.
