B1DE / PrintEvent ..

Question

I am trying to think of a way to capture the output from a document print ( a sales invoice) so that i can do some additional processing on a subset of the printed items (export them to an external file) . I am using B1DE to create my application and the event handlers but i'm having a a problem with the printEvent  - namely where to put it and how to name it  ? I can add a handler to the "ok" button on the Document print dialog but this receives an ItemEvent and i'm not sure that this can or should be cast to a printEvent .. Is it just a case of capturing the print event from the main menu and doing all my processing within there  ?  I'm hoping the printEvent will hold the necessary info for me to extract what i want . In the main class B1DE generates a number of event handlers (eg OnShutDown(), OnCompanyChange() ...)  that i can overide but i dont see anything related to printEvents ..
How can I handle this within B1DE framework  ? 
Thanks  ..

Answer 1

Thanks for the reply  .. I did try this within the main addon event handling application class generated by B1DE  ..
In the constructor ..
public Sample() {
            // ADD YOUR INITIALIZATION CODE HERE     ...
            // Add an event handler for the print event  ...
            B1Connections.theAppl.PrintEvent += new  SAPbouiCOM._IApplicationEvents_PrintEventEventHandler(myPrintEventHandler);
and this for the event handler in the same class .. 
  private void myPrintEventHandler(ref SAPbouiCOM.PrintEventInfo pVal, out bool BubbleEvent)
            BubbleEvent = true;
            B1Connections.theAppl.MessageBox("The Print event has been sent", 1, "Ok", "", "");
But the code is never called  ..  Would you happen to know if this is the correct way to add this handler
via B1DE  ?
As an aside i tried one of the samples provided in the SDK(2007A) but with a couple of small amendments  ..
I used the "CatchingEvents" example but added the following 2 lines to register additional listeners ..
// Try these additional events  .. 
        SBO_Application.PrintEvent += new SAPbouiCOM._IApplicationEvents_PrintEventEventHandler(SBO_Application_PrintEvent);
        SBO_Application.ReportDataEvent += new SAPbouiCOM._IApplicationEvents_ReportDataEventEventHandler(SBO_Application_ReportDataEvent);
with this handling code ..
    private void SBO_Application_PrintEvent(ref SAPbouiCOM.PrintEventInfo pVal, out bool BubbleEvent){
        BubbleEvent = true;
        SBO_Application.MessageBox("The Print event has been sent", 1, "Ok", "", "");   
    private void SBO_Application_ReportDataEvent(ref SAPbouiCOM.ReportDataInfo pVal, out bool BubbleEvent)
        BubbleEvent = true;
        SBO_Application.MessageBox("The ReportData event has been sent", 1, "Ok", "", "");   
These events didn't fire as expected either - they didn't fire at all . Can anyone see a problem with my implementation or my interpretation of the event handling  ?  ..
