Specifying time-out for objects?

Hello!

I'm using the following code to automate Word:


Dim nWord As Object
Set nWord = CreateObject("Word.Application")

nWord.DisplayAlerts = 0 'wdAlertsNone
nWord.Documents.Open (uFile)
nWord.Selection.WholeStory

However, it sometimes happens that the code is stuck at

nWord.Documents.Open (uFile)

The only thing that helps then is to manually kill the Word process in the taskmanager.

How could I define time-out so that VB6 stops trying and I don't have to kill Word in order to make my application working again?

Thank you!

ps: The problem why it would hang was that there was a loading error. Word prompted me this error when I started Word from outside VB6). I was expecting that using the "OpenAndRepair" option would automatically fix this, but it still hung when I used these arguments:

nWord.Documents.Open uFile, False, True, , , , , , , , , , True 'the last argument defines "OpenAndRepair"

if the file is a word docuement, you could try

Code:

---

set ndoc = getobject(ufile)

---

that way you should be able to handle any error

better to fix the file so it opens correctly

What would I do with nDoc then?

ndoc would be the document object, so you can use any property or method of a document, or ndoc.application would be the application object

I should have stated the entire code. I'm trying to get the text of a Word document like this:

Dim nWord As Word.Application
Set nWord = CreateObject("Word.Application")

nWord.DisplayAlerts = 0 'wdAlertsNone
nWord.Documents.Open uFile, False, True, , , , , , , , , , True
nWord.Selection.WholeStory

GetText = nWord.Selection.Range.Text'return the text of the Word document

nWord.ActiveDocument.Close False

nWord.Quit False
Set nWord = Nothing

Can you please tell me in which way getting nDoc separately would help me?

Is the n prefix in nWord and nDoc like hungarian notation's n for Integer?

cheers,

No. Before "var" become popular, I used "n" to indicate to myself that a variable would only be used within a sub or a function.

Code:

---

Dim nWord As Word.Application
Dim nDoc  As Word.Document

Set nWord = CreateObject("Word.Application")

If nWord is nothing then
  'unable to automate Word
  'handle this situation here

  GoTo PROC_EXIT
End If

'set properties
With nWord
    .Visible = False
    .DisplayAlerts = 0  'wdAlertsNone
End With
   
'open the document
Set nDoc = nWord.documents.open(uFile)

If nDoc is Nothing Then
  'unable to get the document contents
  'handle this condition here

  GoTo PROC_EXIT
End If

'read the contents from the Doc object
GetText = nDoc.Content

PROC_EXIT:
Set nDoc = Nothing
Set nWord = Nothing

---

I use something like this and have never seen the lockup you experience.

Thank you very much. If nDoc is NOT nothing, do you think I should destroy the nDoc and try to load the file with nWord.Documents.Open()?

If your goal is to get the text contained in the document, you don't need to interact with the nWord application object any more once you get a reference to the Doc. The nDoc object represents the Document itself and can be used to get the text from the document with this single line:

Code:

---

GetText = nDoc.Content

---

I've edited my original code to include this as well.

There's a tutorial of sorts on Word Automation on this forum. Check it out:

Thank you very much!!!

To control the timeout period for OLE automation attempts, these two properties of the App object can be used:

App.OleRequestPendingTimeout
App.OleServerBusyTimeout

See "Controlling Timeout Intervals" article: https://msdn.microsoft.com/en-us/lib...(v=vs.60).aspx

if opening the document is still a problem, there are ways to open xml type documents as xml file and read the text from that, there are several examples in this forum

if the document will open using getobject all you need is

Code:

---

ntext =  getobject(ufile).content.text

---

where ntext is a string or variant
