Function "Type mismatch" Error

I write this function

Public Function CheckWord(RTFName As RichTextBox)
.
.
.
.
end Function

when I call it from a form like this :

call CheckWord (RichTextBox1)

I got an error "Type mismatch" on the line in the form
what goes wrong ?

Thanks

Sorry I forgot

When You call a function like this you need
to place the "call" word

Call CheckWord(RTFbox)

Is there some reason that you can't just pass RichTextBox1.Text? With a function name of CheckWord it doesn't seem that you would need to access any of the other properties.

If you must pass the control, do this:

Code:

---

Public Function CheckWord(RTFName As Object)
Dim rtfn As RichTextBox
Set rtfn = RTFName

---

And I forgot to mention that you also have to type cast the function, i.e. Public Function CheckWord(RTFName As RichTextBox) As SOMETHING

Also, after looking into the matter, I realize that your original declaration (plus the cast) will work. I wrote a quick test with CheckWord returning the contents of RTFName.Text.

Code:

---

Private Sub Command1_Click()
  Text1.Text = CheckWord(RichTextBox1)
End Sub

Private Function CheckWord(RTFName As RichTextBox) As String
  CheckWord = RTFName.Text
End Function

---

I tried leaving the "As String" off to see if it would cause the error. No error, but also no returned string. Maybe this will still give you something to try.
