Trap 'close' in Crystal viewer?

I think this comes under the API juristiction.....

How can I catch the 'close' event from a Crystal Report viewer preview window? The help given in the Seagate help files doesn't help me much.

I do something like.....

Code:

---

    Set crwApp = CreateObject("Crystal.crpe.application")
    Set crReport = crwApp.OpenReport("D:\DVD Ordering System\Reports\DVD002.rpt")
    Set repView = crReport.Preview

---

which is fine except that the viewer is not modal. I either want to be able to set the view to modal or loop until the viewer is closed by the user - but I don't know how to achieve either. The help does mention API calls but these examples aren't in VB, and I'm far too much of a cabbage to figure out how to translate them!

You can use the IsWindow API on the Views Parent's WindowHandle property, i.e.

Code:

---

Private Declare Function IsWindow Lib "user32" (ByVal hwnd As Long) As Long

Private Sub cmdOpen_Click()
    Set crwApp = CreateObject("Crystal.crpe.application")
    Set crReport = crwApp.OpenReport("D:\DVD Ordering System\Reports\DVD002.rpt")
    Set repView = crReport.Preview
   
    While IsWindow(repView.Parent.WindowHandle)
        DoEvents
    Wend
   
    MsgBox "Done"
End Sub

Thanks Aaron, I'd got some assistance on this from another thread. Think Seagate should add a nicer interface to their viewer to allow this without API's though!
