vb.net How can i kill the application that i created using createObject()

Question

I'm using CreateObject(progId) in Vb to create a pdfDOcument. But the problem is that after i'm done and closing the document and release, How can I shutdown the process?

How can I reference the process and know if it was already open by the user before I created the object? And how can I kill the process if the process was not running before I created the object (pdfDocument)?

Is there better strategies than to use CreateObject()?

Answer 1

The solution that we've found is to create the application object before we create any application's object.

For example:

dim objApp as object = CreateObject("AcroExch.App")
dim objDoc as Object = CreateObject("AcroExch.document")

...
objApp.CloseAllDocuments()

System.Runtime.InteropServices.Marshal.ReleaseComObject(objApp)
System.Runtime.InteropServices.Marshal.ReleaseComObject(objDoc)

But next time I will never use CreateObject. I'll try to use framework classes (especially the Runtime and Reflection for such examples).
