Getting UI resize event block my VI

Hi,
I try to resize a chart if the user is resizing the vi UI.
Unfortunaltly, the option from the menu edition "Resize with the front
panel" is unavailable for my chart (maybe because it's in a tab
panel). So a way to resize it is to get the event "UI resize" and to
manage the size of my graphe.
But as I enter in my event, I seem to never go away from this event
structure.
Actually, just to stop my vi with the famous "stop button", I do the
following actions :
I launch my vi
I resize my UI
I put the stop button (its state is changing but my vi don't stop)
I need to resize my UI for the stop button state to be considered and
my VI stop.
I certainly do something wrong ;-(
My event structure is inside the main "while" loop.
I did not
use the option "block the front face until this event ends*"
Thanks for all.
*excuse for the translation, I use a french version.

Bonjour,
J'imagine que dans le code, le bouton STOP utilisé est directement câblé à la condition de fin de la boucle while. Ayant moi même fais le test j'ai un comportement similaire à ce que tu décris dans ta question.
Il vaut mieux ajouter une condition d'événement '"stop":Valeur changée' en incluant le terminal dans la condition d'événement. Ensuite câbler le stop à la condition de fin de boucle.
J'attache un VI enregistré sous LV6.1 pour illustrer cette réponse.
Hope this helps !

Resizing events, and blocking application

Hi,
While developing my application, that displays the state of processes, I observed something I can not duplicate that good. While debugging the app, I observed that when I manually resize the window size, my application could block (as in not response any more and stop running altogether). As said, I can not duplicate the problem. At the moment I can resize the window while it is updated, and the app keeps on running and stays responsive. But to solve this (potential) problem, should I add an event listener like WindowStateListener? Does this method catch window resizing events? And could I then add to my code something like
    public void windowStateChanged(WindowEvent e) {
        repaint();
    }Or, stated otherwise, to what event should I listen so a window resize event can be caught, and used to repaint the window?
Abel

I think that before resizing a windowActivated() event is generated... you could use this to set up your task before the window is resized. Of course, an activation doesn't mean resizing but perhaps it could help.

Issue with TextArea resize event

Hi,
In the following
sample there
is a button and a textarea in a VDivideBox. If you move the
divider, the Textarea is resized and in its resize event I change
the fonts size. It works very well except in one case: If the
Textarea is given the focus and then you try to resize it by moving
the divider, then all the text goes blank ! I've debugged it and
everything looks fine, so I can't figure out what's going on...
I'm using Flex 3. To see the code, right click and View
Source.
Thanks for helping.

Hello,
You say:
"The event trace shows that INPUTFINISHED got triggered. The technical workflow log also shows a record of the terminating event - but still the task does not get finished - the task still remains INPROCESS and does not get COMPLETED."
I would concentrate on fixing this. If an event is being created wth the proper key (check that) then the workflow should pick it up. You say you can even see it in the workflow log? Are you using a wait step, or have you set the event as a terminating event for the whole workflow? Try generating the event manually (with SWUE) to figure out what the problem is. This should work. Check the workflow log for errors.

Query to get the details of Blocking and deadlock occurred for the Day

Hi,
I need a query to get the details of blocking and deadlock occurred for the day.

You havent specified which version of SQL you are using which makes it difficult to give a solution. Assuming its latest versions , by default SQL Server (in any versions) doesnt track blocking information.
You need to run some kind of queries/traces to capture blocking. The same goes with Deadlocks where majority of the DBA's enable trace flag 1222/1205 when they suspect deadlocks happening.
Check this link -
http://dba.stackexchange.com/questions/10644/deadlock-error-isnt-returning-the-deadlock-sql/10646#10646
This link gives code to get historic deadlock information. I havent used it , I just googled to get that.
That being said if you are looking for something to capture for the future check the below links.
Check these links on how to setup extended events to capture deadlock and blocking.

Handling resize event ...

I have a class that extends Panel. I add some buttons
(Min/Restore/Max/Close ... top right corner,etc) to the chrome
using rawChildren.addChild. I'd like to restrict the window to
never be allowed to get to a height less than the height of the
buttons or a width less than the combined width of the buttons
(this is a generalization, I've included logic to account for
borders, etc). Nevertheless, I've tried countless approaches ...
then I tried listening for a resize event ...
//in constructor
this.addEventListener("resize", myResizeHandler);
//handler
private function myResizeHandler(event:ResizeEvent):void{
width = Math.max(someMinimumCalculatedWidth(), width);
height = Math.max(someMinimumCalculatedHeight(), height);
As shown ... within the event handler, I set width/height
properties of the panel. In the case where they are different than
current width/height, it expected it would trigger yet another
resize event .... and I expected to get into some kind of nutty
event loop (as you can see ... I'm in that ** I'll try anything
...** mode). Surprisingly ... it worked properly. There doesn't
seem to be a resize event triggered when I set the width/height to
values different than they were before entering the handler? I've
perused the Panel/UIComponent source and everything I see leads me
to believe another resize event would be triggered.
So ... as strange as it sounds, I'd like to understand why
this works :-) I can't bring myself to just move on without knowing
why another resize event isn't dispatched and why I don't end right
back up in myResizeHandler ...

A lot of times I find I have to go several classes up the
inheritence chain
to find where something lives. A shortcut to this is to find
the public
class extends statement and click whatever it extends. Press

Resize event triggerd on TransistionManager.start ?!

Hello there i got something in AS3 thats a bid odd or maybe im doing something wrong.
I made a small example te clear some things up (see bottom part):
This example relies on 1 MC on the stage called testMc now when you run this code it works fine.
Evry time you click the movieclip in does what its suppose to do.
The output shows
trans
trans
trans
trans
etc
The problem lies when you resize the screen and then press the button again for a few times you will see this in the output
trans
resize
resize
resize
resize
resize
resize
trans
resize
trans
resize
trans
resize
trans
resize
Somehow after the resize is done it keeps calling out for the resize event.
How is this possible ?! and what can i do to fix this problem Ow i made it in CS5 if thats any help
Thanks in advance
import flash.events.MouseEvent;
import fl.transitions.*;
import fl.transitions.easing.*;
stage.addEventListener(Event.RESIZE, stageResize, false, 0, true);
function stageResize(evt:Event):void
    trace('resize');
testMc.addEventListener(MouseEvent.MOUSE_DOWN, testTrans, false, 0 , true);
testMc.buttonMode = true;
function testTrans(evt:MouseEvent):void
    trace('trans');
    TransitionManager.start(testMc, {type:Fly, direction:Transition.IN, duration:2, easing:Elastic.easeOut, startPoint:4});

I don't think very many people use the TransitionManager class or really care about it at all. It is very limited in what it does and isn't very explicable or flexible. That is probably why nobody has responded.
But evidently there is something in the Class that causes a resize event to be fired if the stage has been changed from its original size. BTW, are you testing this just in the IDE test environment? Most likely since it includes trace statements. Have you verified that it still does this on an html page (or whatever your eventually delivery format will be)? I tested it under AS3 in the testing environment and saw what you are seeing. But I haven't tried the other formats.
If you are on a PC you could go into the Class files and add some trace statments in the classes and see where that event might be getting dispatched. The files are at:
C:\Program Files\Adobe\Adobe Flash CS4\Common\Configuration\ActionScript 3.0\projects\Flash\src\fl\transitions
Be sure to make a back up before you go messing with them.
But the best thing to do would be to not use the TransitionManager class!

Window Resizing event

Is there any way to detect a window resizing event? When I grad the corner of a JFrame, I'd like to be able to tell that it is being resized. If anyone konw a way of doing this, please let me know.
Alan

You could have your window implement the ComponentListener interface. There is a method that gets called when the component's size changes.

Resize event

if (EventEnum != SAPbouiCOM.BoEventTypes.et_FORM_ACTIVATE & EventEnum != SAPbouiCOM.BoEventTypes.et_FORM_LOAD)
     SAPbouiCOM.Form oCurrentForm = SBO_Application.Forms.Item(FormUID);
                if (EventEnum == BoEventTypes.et_FORM_RESIZE)
                    try
                        oCurrentForm.Items.Item("PLB").Left = oCurrentForm.Items.Item("10000330").Left - oCurrentForm.Items.Item("PLB").Width - 3;
                        oCurrentForm.Items.Item("PSOB").Left = oCurrentForm.Items.Item("PLB").Left - oCurrentForm.Items.Item("PSOB").Width - 3;
                        oCurrentForm.Items.Item("PLB").Top = oCurrentForm.Items.Item("10000330").Top;
                        oCurrentForm.Items.Item("PSOB").Top = oCurrentForm.Items.Item("PLB").Top;
                    catch { }
//TODO: This is triggered many times. WHY ?????
My goal is to keep 2 custom buttons aside system one but
I tried many things in form_Load, Activate or with things like BeforeAction, etc..etc
I dont know how to make sure that the buttons are really positioned correctly and avoid makeing a call to the resize event many times for nothing
In this actual form, the code make the form flickering many times before get finaly stop.
Else then that, the buttons are very nicely placed and when I resize, they stay right at their place.

Stop answering calls with blocked numbers. If it's someone who really wants to talk to you, they'll leave you a message and you can call them back.

How do I get rid of event details in iCal in iOS?

I'm trying to learn how to get rid of event details in iCal on my iPhone. With the event itself "edit" comes up when I touch the item. For event details, however, the "edit" option does not appear.

Not quite sure what you mean by "details", but after touching Edit for the event, touch the lines with the name and location and a cursor shows with the keyboard to edit those.
Note that you won't be able to edit Exchange synced calendars.
Also note that "iCal" is the OS X app. The iOS app on your iPhone is "Calendar."

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.

I am new to IPhoto 9.5 and I think I missed a step. I uploaded pictures but they do not appear as an event in my library. They are in Last imported only. How can I get them into event.

I am new to IPhoto 9.51 and I think I missed a step when I uploaded my vacation pictures. I uploaded pictures but did not import them into the library. They are in L\last imported only. How can I get them into events?

If the Photos are under 'Last Import' or 'Last N Months' then they are in the Library somewhere, just not where you are expecting them to be. We know this as both Last Import and 'Last N Months' are not places, just listings of elements in the the Library.
The two most common reasons that they can't be found is either an incorrect date on the camera or the Sorting (View Menu -> Sort Photos - or Sort Events, as appropriate) has changed.
Quick route to find them: Right-click on one of the images in Last Import and select 'Show Event'. This will bring you to the image in the Library.

FTP Get File List Action Block, It's double listing files! ver 11.5

Hi guys.. I have a good one!   I have an FTP Get File List action block in my BLS transaction. Occasionally, it double lists the files in its output.   For testing I put a repeater with a logevent output where I log the filename, date, and size. Heres what I saw for my action block output.
2009-02-13 00:38:00,963 [UserEvent] : File Name: DMM_Export_0010056.txt, File Date 2009-02-13T00:36:00, File Size 339
2009-02-13 00:38:00,963 [UserEvent] : File Name: DMM_Export_0010056.txt, File Date 2009-02-13T00:36:00, File Size 339
This is xMII version 11.5.6 b73 with java 1.4.2_07
I have a workaround by putting in a distinct action block, after the filelist, but anybody have an idea why this might happen?   My theory is that something might be occuring if the file is being written to while we try to process it, but not sure.
I've been building BLS parsers since 2003, (Remember those fun times with Jeremy?)   I've never seen this happen.

My example is a sample log file before the distinct action. The general log shows nothing other than the subsequent transaction errors I get as a result of running the same error twice (Tcode return from BAPI calls etc)
Here is something else interesting.. my userlog file is acting funny, like its trying to write on top of itself. could it be the transaction is actually running twice or parts of it?
For example look at the following log entries
This is how my log file entry for a production confirmation should look
2009-02-13 00:38:06,854 [LHScheduler-Int10_NestingWOProdConf] INFO   UserLog - [UserEvent] :
However sometimes... its looking like this...
2009-02-13 2009-02-13 00:38:11,854 [LHScheduler-Int10_NestingWOProdConf] INFO   UserLog - [UserEvent] :
Like it started writing to the log, then started again.
The problem we are having is that we have JCO calls to SAP in this transaction that does goods movement, we get locking / block errors back from our saying that we (our sap account) is already updating the information.   Sometimes the information would be posted twice! You can see how this has become a HUGE issue posting data to a LIVE system twice.
This is happening on 2 xMII servers.
