Can a CIN node raise an event?

Just curious. I am able to pass the event struture to a CIN node it appears as "LVUserEventRef *userEvent" (and I found 'typedef MagicCookie LVUserEventRef;' in extcode.h). But I am unable to find "cookie.cpp" mentioned in extcode.h So is the information available somewhere about this ???

Unfortunately the information you are looking for is part of the source code for LabVIEW and is National Instruments Confidential. It cannot be release to the public. I'm sorry for any inconvenience this creates.

Hi,
Can any one help me on the below issue ?
while executing automated test case in test center it is showing as test case is in progress, then i navigated to virtual machine (where the test agent is online), there Internet

progress, after 2 or 3 min some of test cases getting passed and some are failed.
Here my question is in lab center-->virtual machine, IE has opened automatically and navigated the 2 or 3 links and with in seconds IE has getting closed. Why IE is getting closed without completing execution?

How can i raised custom event permanently?

how can i change above code to raise event whenever file size has been larger than threshold?
what is advantage of Event when I can use following code instead?
using System;

var file1 = new FileSizeMonitor("C:\\1.txt");
file1.CheckFileSize();
thank you/.

Hi, if your files keeps growing in size...you can add a thread, may be with background priority, in your first code which will check size of file at some interval and if at any instance it found it larger than the limit it will raise the event
which can be used to show error message.
Here is a your modified code...

U00BFHow can I raise an event from visual basic to BW?

Im looking for simple vb code that will raise and event that will trigger some process chains I have in bw.
something similar to
Set R3 = CreateObject("SAP.Functions")
R3.RaiseEvent("myEvent")
I'm sure I saw the code before, but I have looked for hours and couldnt find it again.
Thanks!
David G

Hello, this is how I finally did it and it is working pretty well.
In SAP
1. In SM62 Create new Event: ZGDREV01
2. In RSPC (Process Chain Maintenance)
- Start Variant after Event : ZGDREV01
Periodic Job: Checked (other wise it wil just trigger once)
3. In SE37 Created a new function module:
Attributes: Remote-Enabled Module
Import: EVENTID (char string)
Source Code:
FUNCTION ZGDRFM08.
*"*"Local Interface:
*" IMPORTING
*"     VALUE(EVENTID) TYPE ZTXTSH
CALL FUNCTION 'BP_EVENT_RAISE'
exporting
eventid = EVENTID.
ENDFUNCTION.
4. In Visual Basic
Public Const TRANDATA_EVENTID = "ZGDREV01" ' EventId to be Raised
Private Sub cmdStartLoad_Click()
   Dim R3 as object
   Set R3 = CreateObject("SAP.Functions")
   Call TriggerLoadEvent(R3, TRANDATA_EVENTID)
End Sub
Public Function TriggerLoadEvent(ByRef R3 As Object, ByVal event_id As String) As Boolean
    Dim FuncVal As Object
    Dim param_event As Object
    On Error GoTo errHandler
    Set FuncVal = R3.Add("ZGDRFM08")
    Set param_event = FuncVal.Exports("EVENTID")
    param_event.value = event_id
    TriggerLoadEvent = FuncVal.call
    Exit Function
errHandler:
    MsgBox Err.description
End Function

Raise an event from do_prepare_output

Hi All,
I have a requirement where I need to raise an event after having defaulted a value in a dropdownlist field.
I'm working on component BT120H_CPL/NewComplEF.
Here I have to default a value in the field REFOBJECTTYPE (context node NEWCOMPL). This is not a problem, I actually managed to write my logic in the do_prepare_output.
My problem is that upon selecting a value for this field the event ONREFOBJECTTYPE is executed, unfortunately if I default a value the server_event 'select' is not triggered and the sub-screen ExtRefItemEL is not called.
Do you know how to push/simulate an event from do_prepare_output in order to call the sub-screen immediately?
Thanks in advance
Paolo

Hi Paolo,
You can call the event handler ONREFOBJECTTYPE
from do_prepare-output by calling
   CALL METHOD me->eh_ONREFOBJECTTYPE
* EXPORTING
*    htmlb_event    =
*    htmlb_event_ex = .
please try and tel me know.
Regards,
Taity

Object does not match target type when raising an event from c# to VB6

I have a c# .net DLL that I use from a VB6 app. It exposes an event,
and the VB6 app is sinking it.
The VB6 app is receiving the event, as long as it is raised from the
main thread of the .net DLL.
I have an aync task being handled inside the DLL (delegate BeginInvoke). Any
attempt to raise the event from within that thread casuses the reported
error, even from within the AsyncCallback function, when the thread is ending.
I noticed that the delegate for the event is not declared inside the
interface. It's in that module, but above the interface definition:
    [ComVisible(false)]
    public delegate void LoggingEventHandler( string logData );
The event is declared in the class itself as:
    public class Processor : _Processor
        public event LoggingEventHandler        LogNotification;
Finally, to raise the event:
if ( this.Completed != null )
    this.Completed( true );
If I open the tlb with OLEVIEW, I can see the public event just fine. Of course, I expected to, as it's working up until the helper thread kicks in.
Now for the REAL WIERD PART! This DOES work on several servers that have
been in production for months. It's just this one server that it won't work
on. Same code. Resinstalled/registered it 1,000 times. It took me a while to
find that an error was even occuring, since it was being raised in the
seperate thread. In other words, I'm receiving the event just fine on a series of servers. This is a new machine we're trying to bring online. I suspect it's environmental, but I can't figure it out.
I don't understand why the publisher would be expecting a certain type of
subscriber in the first place... unless the error is really triggered by the client when the event reaches it. I've put logging into the client, though, and the first line of code inside the event is not being executed.
For the VB6 app, I reference the tlb file that is automatically created when
I compile (Interop is checked). I unregistered and re-registered the tlb on
the server. I regasm'd the dll itself. All dlls are in the same folder - not
in the GAC.
The stack trace is as follows:
   at System.RuntimeType.InvokeDispMethod(String name, BindingFlags
invokeAttr, Object target, Object[] args, Boolean[] byrefModifiers, Int32
culture, String[] namedParameters)
   at System.RuntimeType.InvokeMember(String name, BindingFlags invokeAttr,
Binder binder, Object target, Object[] args, ParameterModifier[] modifiers,
CultureInfo culture, String[] namedParameters)
   at System.RuntimeType.ForwardCallToInvokeMember(String memberName,
BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData&
msgData)
   at HPFS.Queue.IProcessorEvents.LogNotification(String logData))

This is driving me nuts!
I sure would appreciate any suggestions.
I got this working on one of the two machines. The other machine had some other issues, so I had it re-imaged. It's been so long since I fixed the first one, that I can't remember exactly how I did it. Plus, I did so many things to it over two weeks, that I never really felt confident, anyway. But ... I could *swear* that the last thing I did back then to get this event to flow was to re-register the DLL's TLB.
So ... This is win 2k with FW 1.1 + SP1.
Completed is the delagate I'm trying to invoke.
this.Completed.Target.GetType().Name = "__comobject"
I've tried everything. Unregistered the .tlb. Unregistered the .net DLL. Verified that the app completely failed while unregistered. Created the TLB using RegAsm /tlb syntax.
I tried using CLR SPY. It registers nothing. It only lets me pick an EXE. This is a DLL tring to raise to an EXE.
I've looked at the TLB in OLE VIEW and I just don't know what I'm looking at.
Is there any other tool or technique I can use to audit/monitor/trap this? .net is giving me *** for details about what's failing. I wish I could somehow debug into exactly what it's trying to do and get more details on the failure.
Here's the error I'm getting:
(Code -1) Object does not match target type.<Source:mscorlib>(Stack:    at System.RuntimeType.InvokeDispMethod(String name, BindingFlags invokeAttr, Object target, Object[] args, Boolean[] byrefModifiers, Int32 culture, String[] namedParameters)
   at System.RuntimeType.InvokeMember(String name, BindingFlags invokeAttr, Binder binder, Object target, Object[] args, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParameters)
   at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
   at HPFS.Queue.IProcessorEvents.Completed(Boolean success)
   at HPFS.Queue.Processor.RequestDone())
Processor = the DLL I'm trying to raise the event from.
IProcessor = the event interface that's exposed through COM.

Raise an Event in Redwood after a Commit to an External Oracle DB?

Hello Netweaver Community / Redwood specific,
I am at customer site and have been presented with the following scenario and subsequent question...
The scenario is that there is a 3rd party product (powerBuilder program / windows executable) that is updating an Oracle database on a server outside of the SAP landscape. This PB program is writing records to the oracle db that need to be picked up by XI process. The idea is that after the PB program makes its COMMIT of the records, then the XI process needs to be triggered to start so it can pick up the records.
So the question is... How can an event be raised in Redwood after a COMMIT of records has been made to this oracle DB that is on a server outside of the SAP landscape?
I am familiar with (and we are already doing) the raising of an event in Redwood from an ABAP program with function module that raises external events.
This is what I know - please do not hesitate to ask for further clarification.
Thank you,
Dean Atteberry.

Carol,
Sorry for the delay! I am not that frequent to SAP forums. You can write to me on my mail if you have something important. We can always update forum note for everyone.
I do not know XI that well. But If I understand correctly, you can trigger events in it based on arrival of a file. You can create a dummy job in Redwood on Unix or any filesystem you use to create a zero byte file once Powerbuilder job is ready.
Let me know if this helps!

Raise an event when an idoc invoice (INVOIC02) gets created in error

Hi All,
Im trying to generate an email message from an output invoice when processed incorrectly.
I created a subtype of IDOCINVOIC, updated the linkage table using swe2 but the events are not raised when I go to re-issue my invoice output.
I know its possible to raise these events in idoc invoice exit ZXEDFU02 but the status is not created at this stage.
Is it possible to raise an event when an idoc invoice gets created in error?
King Regards
Ann

@CoolDadTX -That's because I've written com servers in the past using VB.net, however they were not registered with the Running object table.
What I'm trying to do in this case is have an application that will be started by the user, and then they will start another application written in .Net to connect to that first application. The reason for this is that we have an application
written in an old version of smalltalk that doesn't seem to support getObject but can create an IUknown, and we already have base classes to attach to COM objects written in .Net. As this new application needs to be started first it can't be tightly
coupled to the legacy application, so we are trying to register the new application and then connect a Dotnet Client that is being started through a COM Interface from the legacy application. I know it's convoluted but we need to keep the legacy
application alive for a bit longer while we rewrite it as an add-in for the new application.
The article that you linked to has been very helpful on the server side, but do you have any ideas as to how I can connect the sink on the client side in C#?

How do we raise an event into R/3 from a BW info-package ?

Hi friends,
Is there a way to raise an event from a BW stand-along info-package into the R/3 system, without using Event Collector..?
I cannot use the subsequent event option in the package itself since that will raise the event only into BW. I want it into R/3. I can probably raise an event from the package to start a process-chain and then add a step in the PC to run a pgm to raise an event into R/3.
But I am trying to see if there is a better and simpler way without having to create a extra PC.
I am on the BW 3.1 system.
Any suggestions/solutions will be greatly appreciated.
Thanks
lz70d71

hi, here is what you do: This addition is with respect to the previous reply
You need an event from BW to R/3
Step1: create a custom FM copy of BP_EVENT_RAISE and making it rfc enable. To make a FM RFC enabled you just need to tick the radio button in the attributes of the FM.
Step2: Create a custome z program in BW and call FM z_bp_event_raise created in ECC.
Step3: call that program in Process chain.
hope this helps. if you need more let me know.
thanks

New feature in SP5: Closing a popup window raises an event

I'm trying to use this new feature that came in SP5, "Popup Enhancement - Closing a popup window raises an event to the containing iView". Can anyone give me an example of how this works? In the configure element for the popup, there is a new field called, 'Closure Event'. I though by adding by event to this new field, that the event will be raised after closing the popup window, but it didn't. What am I doing wrong?

Hi,
you should add an end-point to the popup and/or use the "Close" action.
there's a difference between when closing the popup implicitly or explicitly

How to raise an event from a program

Hi,
I am creating a workflow for HR, the person will request a basic pay change than, this will start the workflow. For this i am making a screen from where i need to triger the event for the workflow.
Does anybody has any idea? of how to raise an event from a program. or has anybody worked on a scenario like this
Khusro Habib

You can also use the FM SAP_WAPI_CREATE_EVENT which is a little newer I think. (I don't have access to a system today so that may not be the exact name of the FM but if you search SE37 under SAPWAPIEVENT* you should find it.
the parameters will be the event name, and the object key. The object key will be the key field of the workflow object you are using.
For example if you were using the saled document object then the object key would be the sales document number. Carefull how you enter the object key, it can be a little tricky on whether or not you need the leading zeros in the input parameter.
Hope this helps.

HRMD_A IDoc in error not raising an event

I have workflows enabled for IDocs in error.
If an inbound order IDoc (ORDERS) arrives in status 51, it triggers a workflow.
If an HR master data IDoc (message type HRMD_A) arrives in status 51, no workflow is triggered.
Here is what I have checked:
Partner profile has me as responsible agent in both cases.
Both type linkages are active for IDOCHRMD and IDOCORDERS event InputErrorOccurred.
Both IDocs types are posted in with the test tool and end up in status 51.
When I investigate the event trace, I can see that an event is raised for the ORDERS IDoc but not for the HRMD_A IDoc.
There are no errors in the type linkage status column.
So why would it be that the event is not being raised for the HRMD_A IDoc?
How can I find out what should be raising the event? I guess that there is a function module call to SWE_EVENT_CREATE or SAP_WAPI_CREATE_EVENT.
Kind Regards,
Tony.

Hi Tony,
I am a complete novice to workflow but I have a requirement liek yours to trigger workflow for idocs in error, so I was hoping you could point me in the direction of some documentation/steps on how to do this?

Raise an event with no arguments

In VB.net I can declare and raise an event like this
Public Event SomeEvent()
Public Sub SomeMethod
RaiseEvent SomeEvent()
End Sub
I need to work out how to do this in c# however all of the examples of raising events include event handlers. This won't work for me as I am raising this event over a COM interface, and so I can't send eventargs or non basic types through the interface
to the client application.

OK, Action doesn't work as I end up with the following error
An exception of type 'System.InvalidCastException' occurred in AdtakerInterfaceSampleCsharp.exe but was not handled in user code
Additional information: Unable to cast object of type 'System.__ComObject' to type 'System.Action'.
You asked how to raise an event with no arguments in C# and I gave you the solution for this. You could certainly use an Action to raise an event with no arguments as my sample code clearly demonstrates.
How to call your specific COM interface is a totally different topic.
Please start a new thread if you have a new question. You may also want to provide some more details if you want anyone to be able to help you with this. Remember that the forums are for helping solving specific issues though, they are not for anyone to
write an entire application, class or module for you :)

RAISING AN EVENT WHEN DATABASE TABLE UPDATES

hi all,
i want to raise an event when database table updates.For eg : if a price of a material has been changed then i have to raise an event and run the abap program in back ground.i know transaction SM62 to create event, i dont know about transaction SM64. please give me the procedure how to solve this problem. i dont know work flow. please give me a sample code how to raise event.
thanka and regards
suresh

Hi Suresh
It is important to understand that the SAP architecture abstracts the database from the application.
I think that you should look for ways that the application triggers an event when an update has taken place, rather than the DB.
Two ways of doing this that spring to mind are change pointers (for the ALE interface, see menu SALE) and Business Transaction Events (various things including CRM integration, see menu FIBF).
The latter works very well for sending prices to CRM when they change. I am more familiar with this than ALE so I will discuss it.
If you go to menu FIBF and then follow menu path Environment -> Info System (P/S), and then run the report for event 00503301, you can find documentation and a sample function module that you can copy.
Once you register your new function module in the event tables then it will be called when prices are changed.
Cheers

Using cin node in labview error happen

my name is Juan Chen , I wish to use cin node to calculate crc check code in la view. I use an array as input and a unsigned word as output. when I use while loop, error not enough memory or the memory can only read happen. what is the reason,please.

how to use the call library function node ? in vcplusplus6 environment , if I only do rebuild all that can generate a dll, and don't use command to convert to lsb file. could I need add files cin.obj, labview.lsvb,etl to the project ?
