interop application. I would like to provide you the suggestions as follows: 1. In order to make your question more clear and get further help on this kind of problem, please provide the code snippet especially the Interop part that you consider the most posibility to cause the problem: 2. The thread .NET interoperability -- Handling Managed events in Unmanaged code provides you a good example on trouble shooting this issue by Yi Zhang: Events are subscribed after the object ( in this case, Button ) are created. So when you are calling CauseClickEvent(x,y) inside the constructor of Button, the event Click is not subscribed yet, which have caused your problem. To fix it, simply remove CauseClickEvent from the constructor of Button. To see that your event handler in VB 6 is actually called. 3. In my opinion, the article .NET Interop: Get Ready for Microsoft .NET by Using Wrappers to Interact with COM-based Applications mentioned in the thread is helpful for your to understand the interop issue between managed and unmanaged parts. 4. Another example on debug Visual Basic .NET applications and the Visual Basic 6.0 components that they use, and how to debug Visual Basic .NET components called from Visual Basic 6.0 applications.: Debugging Hybrid Visual Basic 6.0/Visual Basic .

Solved Runtime error automation error '2147467261 (80004003)': Automation error invalid pointer Posted on 2009-03-16 MS Access 1 Verified Solution 7 Comments 2,832 Views Last Modified: 2013-11-29 Hello Experts: I have an AutoExec function called ChangePrinter that captures what the current default printer is (global) and then sets it to a specific printer. On the Switchboard form, in the on close vb6 automation error event, it calls GoDefaultPrinter to change it back to the original printer that Windows was set to prior to the db being opened. I am able to capture the correct printer name if I uncomment the message box in the code. I am able to get the code (autoexec and the on close) to do what I want without errors if I step line by line. When I open the database, the autoexec code fires off without a hitch. When I try to close out of the Switchboard, I receive the error, "Runtime Error '2147267261 (80004003'): Automation error invalid pointer." Any suggestions on how to correct this? Thank you! Option Compare Database Option Explicit Global GBL_Printer As String Public Function ChangePrinter() 'Set Reference to Windows Script Host Object Model \System32\wshom.ocx. Dim w As New WshNetwork, p As String GBL_Printer = Printer.DeviceName 'Gets the default printer w.SetDefaultPrinter ("ImageMaster") Set w = Nothing End Function Function GoDefaultP
