Trigger a server event on iFrame close event

Our ADF application is displayed in an iframe inside another shell application. When user close the Iframe on the browser, the shelll application trigger a javascript event in our client listener and close the iframe. In the javascript event, we then queue a server event using AdfCustomEvent as follow
AdfCustomEvent.queue(lnk, 'serverCloseApplication', {applicationName:sourceApp}, true);
However, it appear that the server event is only triggered intermittently causing our application session clean up code is not triggered.
Is there any suggestion as to how we should set this up given our scenario
Thank much for your helps and suggestions

The problem is that the tab which contain the iframe is not within our product control. The application which control this tab is the shell application. I'm actually requesting the shell application for the exact ability you mentioned. However, i was hoping if there's a better way to approach this while we're waiting for this solution
thanks

Hello,
I am using JDEV 11g. My application catches the browser close event to call a return Task Flow.

Project Server 2010 - Triggering event handler on click event of PDP

Hi,
We are trying to trigger an event handler/ process on click event of PDP page (similar to Project Details Page). Users do not have rights to checkin the project.
So just on click event of pdp - an event handler or process should trigger.
Could you please suggest me best possible way for the same? Thanks.

There may be multiple reasons for this.
1. SharePoint timer Job is malfunctioning:
For this try restarting SharePoint timer Job. through SP Powershell:
Stop SPTimerv4 , Start SPTimerv4
2: SharePoint Cache is full:
Reset SharePoint Cache by deleting all XML files ( except cache.ini
) in SharePoint Cache located in System Drive\ProgramData\Microsoft\SharePoint\Config\<GUID>
3: Check if Microsoft Project Server Event Service is running in Services.msc, try restarting it.

ComboBox Close Event Bug?

Resizing a browser makes dropdown to close but combobox
doesn't trigger the close event. Is there a way to trigger the
close event upon browser resize?
thanks

You could close it yourself upon a mouseOut event.

How to detect an external application close event?

Hello,
I have an executable running at startup (scheduled task) and always
staying alive on my server. When the server is rebooted, I would like
to take some actions (write in a event log, etc) before my application
is closed by windows.
So how can I detect that Windows is closing and that it's time to do the associate actions before the closing.
I've tried the 'Application close event' in an event loop but doesn't seems to work.
I'm using labview 8.2 on Windows server 2003.
Thanks in advance!!
Vincent

I tied this and it did capture the application close event. What I did was while running LabVIEW in developer mode I used Windows Task Manager to kill the process. It did throw an Application Close event. I don't have time to try other cases like shutdown or what happens if it is an EXE but hope this helps.

How To Get The CLOSE Event In a JSP File?

Hello everybody,
Right now I am working in a JSP project which is about access log, when the users start , oprate, or close the system, the access log system works. I am in trouble in that when the users close the system, how can I get the close event?
The JSP file contains the following fields :
Close Window
How to add code to get the CLOSE Event and submit to the service?
And If I hit the "Close Button"(on the right-top of the window), how can I get the CLOSE event, too?
Can anyone tell me?

1. Add a hidden field:
<input type="hidden" id="status" value="">2. modify <a href="index.jsp" onclick ="parent.window.close( );">Close Window</a> with <a href="index.jsp" onclick ="closefn();">Close Window</a>3. Add a javascript
<script language="javascript">function closefn(){
document.getElementById('status').value="close";
document.form.action="";
document.form.method="post";
document.form.submit();
parent.window.close( );
}4. Now on the action page get the value of status by request.getParameter("status"); and log it.

Hmmm Strange!!!
Seems like a bug which requires target for parallel effect while hide only but does not set it.
For the time being you can remove the sequence effect as there is no othe effect other than parallel and use effect like

            <mx:WipeUp duration="1000" />

C# COM server events "lost" when raising events while Excel is in edit mode

I posted this question on StackOverflow (http://stackoverflow.com/questions/23798443/c-sharp-com-server-events-lost-when-raising-events-while-excel-is-in-edit-mode) but did not receive a good answer, so I'm trying my luck here.
I have an in-proc COM server written in C# (using .NET Framework 3.5) that raises COM events based on this example: http://msdn.microsoft.com/en-us/library/dd8bf0x3(v=vs.90).aspx
Excel VBA is the most common client of my COM server. 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 know how I can detect this situation on my COM server? Or better still, make the event delegate call block until
Excel is out of edit mode?
I have tried:
Inspecting the properties of the event delegate – could not find any property to indicate that the event failed to be raised on the client.
Calling the event delegate directly from a worker thread and from the main thread – event not raised on the client, no exceptions thrown on the server.
Pushing the event delegate onto a worker thread’s Dispatcher and invoking it synchronously – event not raised on the client, no exceptions thrown on the server.
Pushing the event delegate onto the main thread’s Dispatcher and invoking it synchronously and asynchronously – event not raised on the client, no exceptions thrown on the server.
Checking the status code of the Dispatcher.BeginInvoke call (using DispatcherOperation.Status) – the status is always ends with “Completed”, and is never in “Aborted” state.
Creating an out-of-proc C# COM server exe and tested raising the events from there – same result, event handler never called, no exceptions.
Since I get no indication that the event was not raised on the client, I cannot handle this situation in my code.
I have tested this with Excel 2010 and Excel 2013.
Here is a simple test case. The C# COM server:
namespace ComServerTest
public delegate void EventOneDelegate();
// Interface
[Guid("2B2C1A74-248D-48B0-ACB0-3EE94223BDD3"), Description("ManagerClass interface")]

m_workerThread = new System.Threading.Thread(DoThreadWork);
// Simple thread that raises an event every few seconds
private void DoThreadWork()
DateTime dtStart = DateTime.Now;
TimeSpan fiveSecs = new TimeSpan(0, 0, 5);
while (m_doWork)
if ((DateTime.Now - dtStart) > fiveSecs)
System.Diagnostics.Debug.Print("Raising event...");
try
if (EventOne != null)
// Tried calling the event delegate directly

// Tried synchronously invoking the event delegate from the worker thread's dispatcher.
// Asynchronously invoking the event delegate from the worker thread's dispatcher did not work regardless of whether Excel is in edit mode or not.
System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke(EventOne, new object[] { });
catch (System.Exception ex)
// No exceptions were thrown when attempting to raise the event when Excel is in edit mode
System.Diagnostics.Debug.Print(ex.ToString());
dtStart = DateTime.Now;
// Method should be called from the main thread
[ComVisible(true), Description("Implements MethodAAA")]
public String MethodAAA(String strValue)
if (EventOne != null)
try
// Tried calling the event delegate directly
EventOne();
// Tried asynchronously invoking the event delegate from the main thread's dispatcher
System.Windows.Threading.DispatcherOperation dispOp = System.Windows.Threading.Dispatcher.CurrentDispatcher.BeginInvoke(EventOne, new object[] { });
// Tried synchronously invoking the event delegate from the main thread's dispatcher
System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke(EventOne, new object[] { });
catch (System.Exception ex)
// No exceptions were thrown when attempting to raise the event when Excel is in edit mode
System.Diagnostics.Debug.Print(ex.ToString());
return "";
return "";
[ComVisible(true), Description("Start thread work")]
public String StartThreadWork(String strIn)
m_doWork = true;
m_workerThread.Start();
return "";
[ComVisible(true), Description("Stop thread work")]
public String StopThreadWork(String strIn)
m_doWork = false;
m_workerThread.Join();
return "";
I register it using regasm:
%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\regasm /codebase ComServerTest.dll /tlb:ComServerTest.tlb
Excel VBA client code:
Public WithEvents managerObj As ComServerTest.ManagerClass
Public g_nCounter As Long
Sub TestEventsFromWorkerThread()
Set managerObj = New ComServerTest.ManagerClass
Dim dtStart As Date
dtStart = DateTime.Now
g_nCounter = 0
Debug.Print "Start"
' Starts the worker thread which will raise the EventOne event every few seconds
managerObj.StartThreadWork ""
Do While True
DoEvents
' Loop for 20 secs
If ((DateTime.Now - dtStart) * 24 * 60 * 60) > 20 Then
' Stops the worker thread
managerObj.StopThreadWork ""
Exit Do
End If
Loop
Debug.Print "Done"
End Sub
Sub TestEventFromMainThread()
Set managerObj = New ComServerTest.ManagerClass
Debug.Print "Start"
' This call will raise the EventOne event
managerObj.MethodAAA ""
Debug.Print "Done"
End Sub
' EventOne handler
Private Sub managerObj_EventOne()
Debug.Print "EventOne " & g_nCounter
g_nCounter = g_nCounter + 1
End Sub
This problem also occurs for a C++ MFC Automation server that raises COM events. If I raise the COM event from the main thread when Excel is in edit mode, the event handler is never called. No errors or exceptions are thrown on the server,
similar to my C# COM server. However, if I use the Global Interface Table to marshal the event sink interface from the main thread
back to the main thread, then invoking the event - it will block while Excel is in edit mode. (I also used COleMessageFilter to disable the busy dialog and not responding dialogs, otherwise I'd receive the exception:
RPC_E_CANTCALLOUT_INEXTERNALCALL It is illegal to call out while inside message filter.)
Knowing that, I tried to do the same on my C# COM server. I could instantiate the Global Interface Table (using the definition from pinvoke.net) and the message filter (using the IOleMessageFilter definition from MSDN). However, the event still
gets "lost" and does not block while Excel is in edit mode.
Here's my additional C# code to try to make use of the Global Interface Table:
namespace ComServerTest
// Global Interface Table definition from pinvoke.net
ComImport,
InterfaceType(ComInterfaceType.InterfaceIsIUnknown),
Guid("00000146-0000-0000-C000-000000000046")
interface IGlobalInterfaceTable
uint RegisterInterfaceInGlobal(
[MarshalAs(UnmanagedType.IUnknown)] object pUnk,
[In] ref Guid riid);
void RevokeInterfaceFromGlobal(uint dwCookie);
[return: MarshalAs(UnmanagedType.IUnknown)]
object GetInterfaceFromGlobal(uint dwCookie, [In] ref Guid riid);
ComImport,
Guid("00000323-0000-0000-C000-000000000046") // CLSID_StdGlobalInterfaceTable
class StdGlobalInterfaceTable /* : IGlobalInterfaceTable */
public class ManagerClass : IManagerClass
//...skipped code already mentioned in earlier sample above...
//...also skipped the message filter code for brevity...
private Guid IID_IDispatch = new Guid("00020400-0000-0000-C000-000000000046");
private IGlobalInterfaceTable m_GIT = null;
public ManagerClass()
//...skipped code already mentioned in earlier sample above...
m_GIT = (IGlobalInterfaceTable)new StdGlobalInterfaceTable();
public void FireEventOne()
// Using the GIT to marshal the (event?) interface from the main thread back to the main thread (like the MFC Automation server).
// Should we be marshalling the ManagerEvents interface pointer instead? How do we get at it?
uint uCookie = m_GIT.RegisterInterfaceInGlobal(this, ref IID_IDispatch);
ManagerClass mgr = (ManagerClass)m_GIT.GetInterfaceFromGlobal(uCookie, ref IID_IDispatch);
mgr.EventOne(); // when Excel is in edit mode, event handler is never called and does not block, event is "lost"
m_GIT.RevokeInterfaceFromGlobal(uCookie);
I’d like my C# COM server to behave in a similar way to the MFC Automation server. Is this possible? I think I should be registering the ManagerEvents interface pointer in the GIT but I don't know how to get at it? I tried using Marshal.GetComInterfaceForObject(this,
typeof(ManagerEvents)) but that just throws an exception: System.InvalidCastException: Specified cast is not valid.
Thanks.

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.

Can't find an application close event.

I have a script that runs on the document close event. It looks like the document close event doesn't fire when the application is closed while a document is open. I checked for an application close event in the Script listener log, but there wasn't an entry for it, and the document close event wasn't present either.
The script I'm making writes a file in the same folder as the opened document that indicates that the file is in use. Then when the document is closed, the lock file is removed. It works except when you close the application. There is no document closed event firing, so the documents just close and the application shuts down without any events firing.
Is there a way know when the application is closing?
I found a possible work around that would be a huge pain. The idea is about loading a custom external library that performs cleanup when it is automatically unloaded when Photoshop closes. This is the prototype for the function that would do the work:
void ESTerminate (void );
There is another work around that invloves some button that the user has to remember to click to close the application. That would be awkward and open to user error.
I just want the document closed event to fire before the application closes. Thanks for you help!

That's too bad. I don't feel like getting a whole build environment setup for CS just so I can get a pre-close event in Photoshop. I implemented a script that the user will run in order to close photoshop. I saved a shortcut to the script in "C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Presets\Scripts". The script closes each document and runs my event handler. Then it exits. Check it out, it seems to work:
#target photoshop
//user will run this script instead of hitting exit button
var MLAB_CUSTOM = new Folder($.getenv('MLAB_CUSTOM')).absoluteURI
var docs = app.documents
for(var i = docs.length-1; i >= 0; i--)
docs[i].close()
$.evalFile(MLAB_CUSTOM+"/Ps-FileLock/PsLock-OnDocClose.jsx")
photoshop.quit();

Item close event is triggering twice for Advanced Data Grid

HI, I'm using AdvancedDataGrid for my project. My issue is when click on item close, the item close event is triggering twice. Why it is triggering twice? Thank you...

Hi,
Would you mind reposting your question over on the Flex forums? You'll most likely have better luck over there.
Thanks,

Event structure: have one event trigger another event

I have an event structure with two events. I want the finalization of the first event to trigger the second event. Both events are triggered by a boolean value change, say "boolean 1" and "boolean 2". Can I have a local variable of boolean 2 inside event 1. By changing its value, it should trigger event 2. However, this doesn't seem to be working. (see attached example)
any help?

Tim's reply is the answer you are looking for.
I would like suggest that you create a sub-VI that doesw the work in the second event you want to fire so tht rather than resorting to having one event trigger another, you can simply use the sub-VI that does the work in event_2 after the sub-VI that does the work for event_1.
If you decide to stick one event triggering another, please clearly document the sceme in BOTH events. What you want to avoid is latter deciding event_1 should be triggered by Event_2 and the next thing you know, your app hangs.

Problems with close event scripts and closing Photoshop

Hi!
We are having problems with close event scripts ("Cls ") when closing/quitting Photoshop.
The close event scripts are working without problem when closing an image. But when quitting Photoshop without having closed all images we are observing the following behaviour:
with CS2 the close event scripts are not triggered at all
with CS4 the close event scripts are triggered and executed correctly. But after that the Photshop process freezes. No visible GUI, you have to kill the process with the task manager.
I can reproduce this behaviour even with a small script consisting of a single alert('hello') and even an empty script. Is this an known bug or am I doing something wrong?
Thanks for your help!
