Vba 4605

Hi
I am pretty new to the ASPs. I am developing an application that will be running word document in an IFRAME in an ASP page. When I try to save the contents of the word document, I am getting the error 4605. "The document is in use by another application.". This is working fine in some systems, and some systems throw this error. What should be done in the code to avoid getting this error and saving the document.

The custom save function is as follows;

Function save_document()
Dim wrdApp
Set wrdApp =Getobject(, "Word.Application")

If Err.number<>0 Then
MsgBox("creating word application")
Set wrdApp = CreateObject("Word.Application")
else
MsgBox("getting the existing instance of word")
End If

If wrdApp Is Nothing Then Exit Function
If not (wrdApp.ActiveDocument.ReadOnly = True) Then Err.Number = wrdApp.ActiveDocument.Save
ActiveDocument.Save
MsgBox ("Error = " &Err.number & ". " &Err.Description)
If Err.Number <> 0 Then
MsgBox "Error saving the Document" , vbInformation, "Saved"
else
MsgBox "Section has been saved" , vbInformation, "Saved Successfully"
End If
else
MsgBox "sorry readonly section cannot be saved" ,vbInformation, "Access Denied"
End if
Set wrdApp = Nothing
End Function

What might be wrong in this code to get the VBA Runtime Error 4605 ?

Thanks in advance.

Hi

The problem is, the code works fine in one machine and does throw error 4605 in my machine. What have to be done to make it as machine independent / word settings independent code ?

Thanks,
