In VB.NET code, this will activate a COM instance of Inventor. Make sure you've included a reference to the Interop DLL.
Declare a variable like this:
{code}
Private m_objInventorApplication As Inventor.Application
{code}
And put this in a method to create a new instance of Inventor.
{code}
Dim t As Type = Type.GetTypeFromProgID("Inventor.Application")
m_objInventorApplication = CType(Activator.CreateInstance(t), Inventor.Application)
{code}
When your Inventor.Application.Ready is true, you're all set to start opening documents and doing stuff to it.
When you're ready to shut it down, call this:
{code}
If m_objInventorApplication IsNot Nothing Then
m_objInventorApplication.Quit()
System.Runtime.InteropServices.Marshal.ReleaseComObject(m_objInventorApplication)
m_objInventorApplication = Nothing
GC.Collect()
GC.WaitForPendingFinalizers()
GC.Collect()
End If
{code}
If you don't close a COM activated instance in your program and release it like this, then the process won't actually end.
