iMacros component: Calling and recursion protocol

Post by BGood » Fri Aug 19, 2011 7:22 pm

In my test integration of the iMacros component with my application, I created a class which closely follows the structure of the sample TestComponent_VB/Form1.vb. My code-behind has a new() constructor which instantiates the iMacros component and adds the control to a windows.forms.container control as follows:

#Region "iMacros"
Public Sub New()
iim = iMacrosControl.Create("myKey")
iim.Dock = DockStyle.Fill
AddHandler iim.BrowserStatusUpdated, AddressOf iim_BrowserStatusUpdated
End Sub ...

The calling protocol I typically use for windows forms is or class.showdialog(), but because it appears that the iMacros component requires initialization via constructor, I am activating the form as follows:

Dim frm As New iMacrosForm

I have tried this several different ways, but the problem I am having is that the iMacrosForm instance runs fine the first time it is called, but after the form is closed, if the form is activated again I get the following runtime error:
System.Runtime.InteropServices.InvalidComObjectException was unhandled
Message=COM object that has been separated from its underlying RCW cannot be used.
I have tried calling dispose() in the close event of the form and elsewhere and presume that I am invoking the iMacros form improperly. Is there some additional documentation on how to do this? Thanks.

Thank you for pointing this out.

The fix for this issue is going to be available in the next Component release (version 7.50)
