Search in Word document?

[Pirre001]

I have several Word .doc files listed in a listbox and I need to search all of them to see if a certain string of text is found. I don't want any of the documents to be opened, I just want the name(s) of the documents that the text is found in, to be returned to the listbox. It should only show the founded documents in the listbox.
This far have I come with the code, as I think peet wrote. But this code are far away from complete and not okej for my purpose...

Option Explicit
Private objWord As Word.Application
Private wd As Word.Document
 
Private Sub Command1_Click()
   
    If objWord Is Nothing Then
        Set objWord = CreateObject("Word.Application")
    Else
        Set objWord = GetObject(, "Word.Application")
    End If
    DoEvents
    Set wd = objWord.Documents.Open("c:\Test.doc")' Here i want it to get the file from the listbox.
 
    With wd.Content.Find
        .Text = "test"
Wrap:=wdFindContinue
    End With
    objWord.ActiveDocument.Close False
    
    'objWord.Visible = True
    If Not (wd Is Nothing) Then Set wd = Nothing
    If Not (objWord Is Nothing) Then objWord.Application.Quit
    If Not (objWord Is Nothing) Then Set objWord = Nothing
 
End Sub
