C++ COM Catch Return Events
I have been using the C++ COM iTunes Interface for a while in my application to import files into iTunes via the SDK.
This has been working fine for a couple of years now however I have come across an issue with the deployment of iTunes 9 and greater.
In some machines the iTunes hangs while converting a file and importing to a playlist if I close my application that links into it the convert and import completes fine, this is not on all machines but a couple of customers have raised this issue.
I was wondering if anyone has implemented some form of catching the return events instead of having to sit in a while loop constantly calling:
hr = spConvertOpStatus->get_ProgressValue( &progressValue );
till it is complete. Any help would be greatly appreciated on this issue.
Regards,

Hi Jason-F,
I’ve found that when I raise COM events while Excel is in edit mode (e.g. a cell is being edited) the event is “lost”. Meaning,
the VBA event handler is never called (even after the Excel edit mode is finished) and the call to the C# event delegate passes through and fails silently with no exceptions being thrown.
Do you mean you didn't raise EventOne event? EventOne handler like following?
' EventOne handler
Private Sub managerObj_EventOne()
Debug.Print "EventOne " & g_nCounter
g_nCounter = g_nCounter + 1
End Sub
After test your code, here is my screenshot
And here is my execute log in C# ComServerTest.

How to catch key events in JWindow???
Can somebody please suggest me how do I catch key events in a JWindow. I tried without success with addKeyListener( ) method. My sample code is attached below. I've j2sdk1.4.2_03 in my PC.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class EventCatcher extends JWindow implements KeyListener {
public EventCatcher() {
super();
Container c = getContentPane();
setBounds(100,100,400,400);
c.setLayout(new FlowLayout());
JButton button = new JButton("Hello");
c.add(button);
addKeyListener(this);
requestFocus();
setVisible(true);
public void keyReleased(KeyEvent ke) {
System.out.println("**************");
public void keyPressed(KeyEvent ke) {}
public void keyTyped(KeyEvent ke) {}
public static void main(String str[]) {
new EventCatcher();

can u please take view on my code.
I m trying to move a frame that extends from JWindow on runtime with Key Board Arrow keys. but this only works when I extend this MainApp class from JFrame, but not when from JWindow.
can u please help me. I also posted my own topic but no one response so found it resambling to my problem.
hoping to hear from u soon

RE: (forte-users) Confusion with return event
Samer,
The return event is delivered to the calling task, which is the window in
your first test. It is not deliverd to the event loop of the service object
unless the call to the processor originated in the event loop, which is the
case in your second test. The output you get from the server is exactly as I
would expect.
You need the following code in you client:
event loop
postregister
SomeService1.StartImmediate();
when SomeService1.Proc.ProcessEvent_return do
task.Part.Logmgr.Putline('ProcessEvents_return');
when SomeService1.Proc.ProcessEvent_exception do
task.Part.Logmgr.Putline('ProcessEvents_exception');
end event;
Note that this logoutput will not be written to a logfile, but will appear
in the logwindow which is opened when you start a client application.

Subject: (forte-users) Confusion with return event
I have observed some odd behavior when attempting to
catch a return event for a method invoked using start
task. I provided the primary classes I used during my
test and some output produced by those classes at the
bottom of this message.
The SomeService1 class is used to create an
environment visible service object and the Processor
class is one of its members. The Processor class
starts processing when one of two things happens: the
SomeService1 timer ticks off 10 seconds or when
SomeService1.StartImmediate is called directly by
another entity. Either way StartImmediate is called to
start processing.
The provided output is the result of starting a test
application and invoking StartImmediate from another
object (I used a window) and then observing what
happens when the timer ticks. As you can see the
invocation from the window did not result in the
return event being received. However, the return event
was received when the timer ticked.
According to the Forte documentation a return event
will only be posted to the parent task's event queue.
Since I am making a cross partition call, the window
and service object are not really in the same task
(Unless my assumption is wrong). That would explain
why the window did not cause a return event to be
generated but was an event generated but not caught
and if so where did the event go?
In SomeService2 class I added an event StartProcessing
and moved the code from StartImmediate to the
StartProcessing event case in the event loop and
simply posted the StartProcessing event in
StartImmediate. I performed the same test I used when
testing SomeService1. The Traceback output is
identical for the window invocation but the return
event is received this time! Why?
It seems that to guarantee the receipt of a return
event an asynchronous task must be initiated from
within an event loop. Is this correct?
I do not understand this behavior does someone have
any thoughts on this? How can you guarantee the
receipt of a return event?

Subject: RE: (forte-users) Confusion with return event
I think it is always safe to use start task with where complition = event
clause before event loop. The reason is described in Forte Help in the
Complition Clause index:
"Requesting the return and exception events automatically registers the
events for the calling task. When the asynchronous method completes or
terminates, Forté adds the appropriate event to the calling task's event
queue.
This registration is unlike the event registration for the event statement.
In the event statement, the event is registered just before the event
statement is ready to process the event. In the start task statement, the
return and exception events are registered when the task is started, even
though it can be much later on that your application is prepared to wait for
those events. Therefore, only the "parent" task that executes the start task
statement is registered for the completion event of the started task."
and some comments from "Forte Performance and Patterns" page 18:
"When you use the where completion = event clause in the start task
statement, Forte automatically buffer the return event until you register
for it. Therefore, you do not need to worry about the child task completing
before you register for its return event".

Zenon

Subject: RE: (forte-users) Confusion with return event
Yes, if you want the eventloop of the service object to be informed when
the
method on the processor class is invoked, regardless of who invoked it,
then
you should simply post an event as the last statement inside the method on
the processor class.
The return events are only used to inform a partent task that a child-task
has completed. So, only the calling task receives the event, only if the
calling task is inside an event-loop at the moment the child-task
terminates
and only if there really is a child task (method started using "start task
Note, that the calling task doesn't have to be inside an event loop when
the
asynchronous call is made. It has to be inside an eventloop when the
asynchronous task terminates. The following piece of code works just as
well:
SomeService1.StartImmediate();
self.DoSomeOtherStuff();
event loop
when SomeService1.Proc.ProcessEvent_return do
task.Part.Logmgr.Putline('ProcessEvents_return');
when SomeService1.Proc.ProcessEvent_exception do
task.Part.Logmgr.Putline('ProcessEvents_exception');
end event;
However, if the asynchronous task started from within "StartImmediate"
finishes before the client gets a chance to enter its event loop, then
you're too late to catch the event. That's why it's safer to use the
"postregister" function, which makes sure a certain action is not started
untill all events from the event loop have been registered.

Pascal,
So you are confirming that a return event can only be
received in an event loop if a task is started from
within that event loop.
After making your proposed changes I was able to
receive the return event in the window.
I originally wanted the SomeService event loop to
always receive the return event regardless of whether
or not StartImmediate is called by some other entity
or called when the timer ticks. It seems that the only
way to do this is with events. Is that correct?
Thank you for insight,

I don't know how to get around this. When I type "addEventListener(" and hit control+space bar, I see "Event.MOVIE_FINISH" on the list, citing my custom component as the source. Even when I had it called movieFinish in the component, I still saw "MOVIE_FINISH" for my event in the code help. So, I changed the name, but I cannot get rid of the error, and therefore my program won't compile fully. Any ideas?The first argument to addEventListener() is just a string. You can do:
videoScreen.addEventListener("MOVIE_FINISH", loadScreenSaver); -
AWTEventListener: Catch all events after events are invoked
Hi,
i read here about catching all event of my application: http://developer.java.sun.com/developer/qow/archive/19/index.html
But: Is there a way to invoke my eventDispatched method after the
current event was calling?
For example: I need on selecting a Combobox the selected value, not the last
selection.
Thanks.
Regards.Thanks for reply!
I use an ItemListener on my ComboBox, but my problem was that the eventDispatched method was not
called. I did it like this:
getToolkit().addAWTEventListener(
new AWTEventListener() {
public void eventDispatched(AWTEvent e) {
System.out.println(e);
AWTEvent.ITEM_EVENT_MASK
);Is that a problem of JDK1.4.1 ???
So tried it with a AWTEvent.MOUSE_EVENT_MASK to check a combobox in my application
is clicked. It works, but i get always the last selection von the combobox.
74philip: Thanks for your solution, but my "code for the selected event here..."
should be in the eventDispatched method. I cant change my app for any comboboxes. -

Hi all!
I have a problem. I thought it should be easy to implement, but I didn't found solution! :(
The problem is a next one: I have a JFrame that contains some components inside like Panels, Buttons, ... But what I need is a catch all mouse movements inside JFrame even if the event was appeared over these components.
Maximum what I could get is catch mose events over the empty space of JFrame.
Is anybody know how to do it?
Thank you!
VladimirThank you,
That's exactly what I going to do today, but look at this http://forum.java.sun.com/thread.jsp?forum=57&thread=170512&start=0&range=15
That is what I searched for!
Anyway thanks a lot for your cooperation!
Best regards,

Free of goods should not come in return process
Dear sd gurus Have a good day
i have one requirement regarding free of goods suppose if we already given free of goods with main item like 10 pens 1 pen is free( 10 +1)
generally when we do return process for particular document ( return order,return delivery,pgr,return billing) free goods also will come automatically returns but my requirement is only main item only should come in return process not free of goods.bz after taking main item in return process due to damaged goods ,here only main item only should come not free of goods
how i can achieve this ?
thank youVenu,
I did some searching in copy control (IMG), in view of your business requirement.
In connection to my earlier post, "re-determination of Free goods" in RE order type;
when RE order is created with reference to OR
In VTAF, see item level TANN, copy control 302: Do not copy
Here the free goods are not copied. Only goods with item category other than TANN are copied from billing document to RE order.
Then if free goods determination is done afresh in RE order. If there is no free goods procedure assigned to RE sales document type, then no free goods are populated in RE order.
I haven't tested this, you could test this and see if it meets your business requirement.
From SAP, F1 help for copy requirement 302:
In this requirement, any items that have this requirement assigned will not be copied into the target document.
Example
When using product selection, it is advisable that only the main item be allowed to be copied from document to document, and the sub-item should be re-determined in the target document based on the current availability situation. In order to implement this, the item category of the sub-item can have this copy routine assigned to it in order to prevent the copying of these items. -

Catching key events in application
I have a JFrame with a JDesktop containing lots of JInternalFrame with various of components such as JTextFields etc.
Now, i want to have a "main" listener that will catch key events no matter which component that has focus. For example pressing CTRL+A should produce something in the application no matter which component that has focus.
How do I implement this in an easy way?It doesnt seem to work to add a KeyListener to the JFrame...
this.addKeyListener(new KeyAdapter(){
public void keyTyped(KeyEvent e){
System.out.println("KeyTyped()");
public void keyPressed(KeyEvent e){
System.out.println("KeyTyped()");
});Adding that to the JFrame gives nothing to System.out when a JTextArea inside an JInternalFrame has focus. -

Where can we catch the event which leads to downloading a report to a local
Hi frnds,
can u help me out . actaully ,i have a classical interactive report. it has many headings.Because of the initial headings ,if i try to download that report to a local file ,the column allignments are disturbed.
So,one way i feel to get the download correctly ,is that ,some how i can catch the event whcih leads to the download of the report ,and based on the occurence of that event ,i can restrict the page headings to appear in the downloaded spreadsheet ,so that the there are no, unwanted columns getting inserted in between .
Regards
Rajesh.hi,
you can have selection screen field : "parameters : p_disvar like disvariant-variant." and at event selection scree you can call the below function and select the variant create for the report.
"at selection-screen on value-request for p_disvar.
call function 'REUSE_ALV_VARIANT_F4'
exporting
is_variant = g_variant
I_TABNAME_HEADER =
I_TABNAME_ITEM =
IT_DEFAULT_FIELDCAT =
i_save = g_variant_save
importing
e_exit = h_exit
es_variant = gx_variant
exceptions
not_found = 1
program_error = 2
others = 3.
if sy-subrc is initial and h_exit is initial.
g_variant-variant = gx_variant-variant.
p_disvar = gx_variant-variant.
else.
message id sy-msgid type 'S'
number sy-msgno
with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.

How to Catch Return Code(RFC) in XI
Hi
Can any help me out,
I have a scenario , which is posting the data into SAPR/3 through RFC and alternately I would like to catch the exceptions . I need to catch return code in my scenrio, which will be show successfully posted or not as E or U.
My RFC returning the error codes like E, S, and U..so these error codes i need to catch and update into my DATABASE.
This is scenrio , i need to do very urgent manner..please let me know, should i use schronous or fault message types?
please give me logical steps for how to do this?
If it sync messae type, please tell me what is the output message type and input message type..
thank you,
Regards..rambarki!Hi Rambarki,
Just for your information I'll tell you what all you have to develop to complete this scenario.
<b>1></b> Two datatypes. one for the Request(data coming from JDBC Sender) and one for the Response(data going through JDBC Receiver).
<b>2></b> Two corresponding Messagetypes.
<b>3></b> Five Message Interfaces.
i) OutBound/Async with Request.
ii) Abstract/Async with Request.
iii) Abstract/Sync with Request and Response.
iv) Abstract/Async with Response.
v) InBound/Async with Response.
<b>4></b> Message Mapping
i) Message Mapping between the Request and imported RFC.
ii) Mapping between RFC.Response and Response.
<b>5></b> Single Interface Mapping with Source as Abstract/Sync interface and target as RFC with two mapping programs corresponding to Request and Response.
<b>6></b> Integration Process
i) Create container element for request and response interfaces.
ii) Receive step(Asynchronous), Send step(Synchronous), Send step(Asynchronous).
Receiver Determinations
i) JDBC --> Integration Process (imported from IR)(OutBInterface: OutBound/Async, InBnterface: Abs/Async)
ii) Integration Process --> R/3 (OutBInterface: Abs/Sync, InBInterface: RFC with mapping program)
iii) Integration Process --> JDBC. (OutBInterface: Abs/Async, InBInterface: InBound/Async).
Hope this works for you. -
Hi,
i have a idea for a program. I want to catch all actions from the users. If the user performed this action with the mouse, i wanna show him a notification with the shortcut of this actions. For example: The user open with the mouse a new tab in Safari the program recognize this and show him a message "Hey you can do this with: Apple + T".
I played around with the
Code:
addGlobalMonitorForEventsMatchingMask:NSLeftMouseDownMask
but i can't find a connection to the Event that has been performed. Is there anybody with a idea how i can do this with build in classes from Cocoa/Objective-c? Thank in advance for your help Greetings from Germany TobiInvestigate Display.addFilter().

ADF Faces EA15: table update not working properly after dialog return event
Hi,
in my application I have a table with read-only records and an edit button for each row.
The button triggers a dialog where one field of of the record can be edited.
The record is a bean which is put into processScope.
After accepting the change in the dialog the bean makes an update in the database changing the order of the records in the table on the launching page.
The return event triggers a re-rendering of the launching page (which I can see from the output of a phase listener) and the table model gets updated but the table output is not updated visually.
However, if I call the dialog on another record I don't get the record I see in the table but instead I get the record which I'd expected if the table re-rendered properly.
Do I have to trigger any kind of event on the table now so that the framework knows that a change has taken place and that the table has to be re-rendered? There is no difference whether I use PPR or not. It used to work in EA14.
Thanks,
AchimIn EA14, the return from the dialog required a full-page refresh (whether the dialog was launched with PPR or not didn't matter). In EA15, it's done with PPR if possible. This avoids the flash (and re-scrolling, etc.), but means you do need to tell us what's going to get changed because of the return. You can use partialTriggers on the table with the "id" of the button to make this happen.
