Hi..handling events in console applications

Hi,
Can anyone tell me how to handle events in cosole applications...
I want to trap the event when a user closes the the console window....
THANKS IN ADVANCE
Rama

Hi,
No, I don't think so. A console application can only read from standard input (and you can read the return key that way). But I don't think that you can detect if ctrl is held down by a user, I think you need an UI for that, but I'm not 100% sure since I haven't had the need for it.

Handling events in BSP application using WML tag Extensions

Hello Everyone ,
We are developing a BSP applications for Mobile handheld using WML tag library. I am looking for some code samples to know how we can handle evevents inside the BSP using the WML tag library.
Can any one of you plesae help us by placing a code snippet for handling onInputprocessing() methods (BSP Using WML Tag extensions).
I mean to ask how we can handle events inside the BSP applications that uses the WML tag library.
I know about how to handle BSP events using HTMLB and XHTMLB tags frameworks.
Thanks for your help in advance.
Thanks,
Greetson

Is this WML tag library something that is supplied by SAP u2013 as a BSP Extension Element? Or are you just using WML tags directly in your layout? I can tell you in general that if you want to generate HTMLB events from regular HTML code you can generate the JavaScript calls using the htmlbEvent tag of the BSP extension library. However your tags have to be running within an HTMLB Content tag for this to work.
If you want to work totally without HTMLB then you need to use the simple HTTP Post but format the input name as OnInputProcessing(<function code>) like this:
<input type="submit" name="OnInputProcessing(ok)" value="OK">
This will cause the OnInputProcessing event handler to trigger without needing any HTMLB tags (this is how it was done in WebAS 6.10 before we BSP Extensions).

How to handle events in Swng

Hi!
I would like to know which one of the following is the best way to handle events in Swing application.
Method 1
Write annonymus inner classes in the same class
Method 2
=======
Write a seperate class which extends the adapter class of the event handling and create an object of that in the main class and assign it to the components with addActionHandler() method.
I am trying to use the second one and I have the following design issue.
I have a class frmMain.java in which I have a frame and to that frame I am adding a panel which consists of 'N' No. of components.
I want to make this panel added to the frame when I click on a menu item (login) and want to remove the panel from frame when I click on a menu item(logout).
I have a main class called Application.java where I create the object of my frame(frmMain.java).
Thanks in advance,
AV

1. Your JFrame is now subject to receive action events from anywhere. You will have to be more careful that you respond only to the right events.
2. If you have a lot of possible consequences to an event(for example, based on button pressed), you'll need a long if...then...else statement to determine what to do based on the source of the event.
3. With individual ActionListener classes, it's easier to add the same listener to multiple components and no need to worry about source.
4. Kind of the same thing: With individual classes, the event and its consequences are so tightly coupled.
End preaching....basically, my style boils down to what I call the tool set vs Swiss army knife rule. Java seems designed around the concept of a large number of specific purpose classes vs a smaller number of multi purpose classes and I think its a design methodology that makes sense, because I believe strongly in functional isolation in my code.

Can't access community members list in event receiver when item is updated in console application

Hi,
we attached an event receiver to a list in a community site template. In the ItemUpdated event we access different lists from the site. Everything is working fine when we update a list item in the web frontend logged in as Administrator (application pool
identity Administrator).
Updating an list item in a console application running as Administrator triggers the ItemUpdated event and accesses all lists - only the Community Member list can't be accessed.
SPWeb spWeb = properties.OpenWeb();
Guid communityMembersListGuid = new Guid("3b56d08b-be6b-408b-a2aa-c08722ad499b");
SPList communityMembersList = spWeb.Lists[communityMembersListGuid];
We added the Administrator with full access to the list, run the code with RunWithElevatedPrivileges and initialized the spSite with the account-token of the administrator. Nothing works.
Any idea?
Greetings Peter

Hi,
Please try to use the following code blow:
SPWeb spWeb = properties.Web;
SPList communityMembersList = spWeb.Lists["Community Members"];
If the issue still exists, I suggest you debug your code and provide the detail error message for further research.

Code source works fine from console application but not from SharePoint interface

Hi;
Please can you help
me to understand why my code below works fine from console application (VS 2010) and not working from interface of my SharePoint collection site :
From console application : the subsite is created and I can to open without any problem
From Sharepoint GUI : the subsite is created but impossible
to open subsite : error 404 page not found ?
The subsite creation is very long (2 minutes) and in concole application When I try to open the subsite just after its creation I have page not found and I must waits (several refresh) more time to open the subsite correctly.
Can be I must to display a PoPup to show the progress creation ?

Hi,
To create subsite using event receiver in SharePoint Empty Project, you can refer to:
Sharepoint 2010 event handler to create subsites
To display a PoPup to show the progress creation, you can use: MessageBox.Show("Hello, world.");
More information:
MessageBox.Show Method (String)

Use sql notification for console application C#

I have developed ucma C# console application which sends IM to users.
Now I want to send IM if any new entry is added in the table
So i want to use query notification .
I have enabled service broker on my database .
And I have added code for sqldepedency in my code file.
as follows.
public static void Main(string[] args)
UCMASampleInstantMessagingCall ucmaSampleInstantMessagingCall =
new UCMASampleInstantMessagingCall();
ucmaSampleInstantMessagingCall.connectionfunction();
public void connectionfunction()
string connectionString = @"Data Source=PIXEL-IHANNAH2\PPINSTANCE;User ID=sqlPPUser;Password=ppuser1;Initial Catalog=Ian;";
SqlDependency.Stop(connectionString);
SqlConnection sqlConnection = new SqlConnection(connectionString);
string statement = "select * from dbo.tblTest";
SqlCommand sqlCommand = new SqlCommand(statement, sqlConnection);
// Create and bind the SqlDependency object to the command object.
SqlDependency dependency = new SqlDependency(sqlCommand, null, 0);
SqlDependency.Start(connectionString);
dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
private void dependency_OnChange(object sender, SqlNotificationEventArgs e)
ucmaSampleInstantMessagingCall.run()
private void Run() { // Initialize and startup the platform. Exception ex = null; try { // Create the UserEndpoint _helper = new UCMASampleHelper(); _userendpoint = _helper.CreateEstablishedUserEndpoint();
Now I want to run this application in the background , so f any new entry is added it will notify my C# application and call run function.
i tried above code but it was not working.
Sample code is avaliableon net but it is for form application and we can see output if we run the form application .
so if i want to run my C# application what should I do?

So i want to call run method when new entry is added in the database . and this application is not like any asp.net form application . In form application we display data when programs loads as like your RefreshDataWithSqlDependency
function . But in my application my application will run (send IM) when any new entry is added in the database . As I need running application to achieve notification , what kind of changes are required?

Hi Sirisha,
          You can get the event code for Enter because you have regitered in the event reciever .
But for the SAVE you will have to set in the PF-status of the screen and not the ALV-grid save .
Please award if helpful.

Handling Events in FXML-includes

Hi!
I am using FXML to define the GUI of my application. As the GUI is pretty complex with many regions and items in it, I have created a separate FXML file for each main region to reduce the overall complexity of maintaining the design.
My parent FXML file, called "Frame.xml", includes those "sub-regional" FXML-definitions using "<fx:include source="RegionXYZ.fxml" />".
What I am now stucked with is, how to handle events in this approach...
Questions:
a) Can I add a separate controller in each of the "sub-regional" FXML-files, like "fx:controller="FXMLRegionXYZController"?
b) Or must I, or even should I, use only a single controller inside the main FXML? Will this single controller be able to recognize and handle actions/events in the included FXML-definitions as well?
c) What is the best approach in general for this?
Thanks,
Jörn

- Yes, you can

- if you could control everything from a single controller but you option (A) is much better
c) What is the best approach in general for this?
- Option (a)

Javascript error in event handler event type = timeline

Hi,
I have a small EdgeAnimate projekt with version 1.5.0 and the local export works fine... I must include the package at a CMS and I update all paths to absolute paths and all files are loading...
but I the animation dont play - I see at the javascript console the follow output
javascript error in event handler event type = timeline   edge.1.5.0.min.js:143
Springender Punkt: Rettungswagen - Der springende Punkt
I dont found any solution... :-((

Hi Scott,
I have gone through your shared composition created in older verion of Edge.
If you open the older composition html page in browser, there already have some of the error messages in the console as you mentioned above like
      Javascript error in event handler! Event Type = timeline.
And as you said with the latest Edge, when you upgrade the old composition, some new error messages gets added to the existing ones.
As in the latest Edge, the whole of runtime has been shake-up, some of the attributes has been removed and are added in different way.
Example: To access timelines of a symbol:
     Old way:           sym.timelines['Default Timeline']
     New way:          sym.data[sym.name].timeline
You need to make some modifications in index_edgeActions.js file like:
     1. Search & Replace "timelines['Default Timeline']" with "data[sym.name].timeline"
     2. And in the code taken from EdgeCommons.js, replace "getVariable("symbolSelector")" with "_variables["symbolSelector"]".
Hope, these changes will remove the new JS issues you mentioned.

How to handle events between two custom components?

Hi ,
i want to handle events between two custom components, example if an event is generated in one custom component ,and i want to handle it any where in the application.....can any one suggest me any tutorial or meterial in this concept...
thanks

Events don't really go sideways in ActionScript by default. They bubble upward. If you want to send an event sideways, you will probably have to coordinate with something higher up in the event hierarchy. You can send the event to a common ancestor, and then pass it down the hierarchy as a method argument.
Another option is to use a framework that supports Injection. There are a number around these days. The one I'm most familiar with is Mate, which allows you to handle events and inject data in MXML. Mate is meant to be used as an MVC framework, and you may want to look into it if your application is complex, but you can also use it to coordinate global event handling if you don't need that level of structure.

Eventhandlers of children of application can not receive custom event dispatched by application

Hello dear Adobe community,
hope you can help me with this issue.
When the application dispatches a custom event, the child uicomponent can only receive the event by using Application.application.addEventListener or systemManager.addEventListener. Simply adding a listener, without application or systemmanager, does not allow the event to be received by the child component.
I want to be able to use the addEventListener and removeEventListener without SystemManager or Application.application, or could you provide a better workaround? How can I use the addEventListener, do I need to overwrite EventDispatcher, which I wouldnt like to do?
Just to clarifiy, if i remove the systemManager in front of addEventListener(CustomEventOne.EventOne,sysManHandleCE,false) it will not add it and will not fire.
The code below is an example for this problem that the event is not getting fired in the right moment. The mainapplication got only a button with the customEventOne that gets dispatched.
public
class MyCanvas extends Canvas{
public function MyCanvas()
super();
width=300;
height=300;
addEventListener(FlexEvent.CREATION_COMPLETE,handleCC,false,0,true);
private function handleCC(event:FlexEvent):void
removeEventListener(FlexEvent.CREATION_COMPLETE,handleCC);
addEventListener(CustomEventOne.EventOne,handleCE,false,0,true);
addEventListener(Event.REMOVED_FROM_STAGE,handleEvt,false,0,true);
systemManager.addeventListener(CustomEventOne.eventOne,sysManHandleCE,false,0,true);
private function handleEvt(event:Event):void
trace("In removed from stage handler");
systemManager.removeEventListener(CustomEventOne.EventOne,sysManHandleCE);
trace(hasEventListener(FlexEvent.CREATION_COMPLETE));
trace(hasEventListener(CustomEventOne.EventOne));
trace(hasEventListener(Event.REMOVED_FROM_STAGE));
private function handleCE(event:CustomEventOne):void
trace("I got it");
private function sysManHandleCE(event:CustomEventOne):void
trace("I got it");
public class CustomEventOne extends Event
public static const EventOne:String = "EventOne";
public function CustomEventOne(type:String, bubbles:Boolean=false, cancelable:Boolean=false)
super(type, bubbles, cancelable);
override public functionclone():Event
return newCustomEventOne(type,bubbles,cancelable);
Thank you in advance,
Michael

I think you need to look at event propogation. The object that dispatches an event will be sitting on the display tree. The event propagates up the tree to the roots. Your canvas should be attached to the application, but even then it sits lower in the tree branches than the event dispatcher, so it won't see the event being dispatched because the event is not propagated to the children of the object that dispatches it but to the parent of the object that dispatches it.
So, your canvas is a child of the application, but dispatching the event from the application means that the canvas doesn't see it because events are notified up the tree using the parent link, not the child links.
You may wish to investigate how the display list and event propagation works and then the MVC pattern.

Capturing keystroke event in console-mode

Hi fellow Java Programmer
I was stumbled upon what to be a simple question
Is it possible to capture the keystroke event inside console-based application
This is my scenario:
I have a thread that is keep running for a predetermined amount of time,
It is doing a background-sort-of-task. According to the requirement, it must be able to detect
when the user press 'R' (which will trigger Reload) or when user press 'Q' (denoting Quit)
I would appreciate if somebody come up with hint / snippet of source code
regards,
Honggo

try something like this...
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String s;
s = br.readLine();
if(s.equals("R")){
if(s.equals("R")){
you also can use s.equalsIgnoreCase("R") if u dont care if its capital or not

Question re-posted: Way to get events from outside application

Hello,
FatCo asked this question but has not got a reply. I have the same question, so I re-post it, hoping someone could give us help. How can we write JNI code to do it on a Windows OS? Assume appliction 2 is a Internet Explorer.
Thank you!

Hello,
is there a way to get events from other applications, either native or java applications?
For example application 1 (Java or not) is getting minimized, is there a way to notice application 2 (Java) about that?

I am not really a Windows programmer so I cannot say how you can get the event notification in C(++) but if you can get it there then there should be no particular problem communicating that information to Java.
This might take the form of creating a thread (all threads are native threads on Windows) which blocks on receiving this event and then notifies the rest of the application somehow, maybe by setting a global flag, using Object.notify() to wake up some other thread to do the processing, or simply by calling a Java method to do all the necessary handling before returning. But there is nothing special about this part.
It all depends on how you can receive the event notification in C++.

Calling Console Application that uses WebBrowser from SQL Server - Not Running

Hi there. I am working in a program automation that needs to get files from a website and put it in a database. It is done but as I need a console application and need webbrowser that comes from Windows Forms, I am trying to call it from the SQL Server using
the xp_cmdshell but when it runs the .exe, it execute the block that is before the Application.Run() command but when it reaches this line, it stay running on Task manager but it not execute my code. How can I fix this? I had first created a Windows form application
but it was not working anyway and then I tried a console application and then I use the [STAThread] and Application.Run(). At least it runs the file from SQL Server but is not executing all my code, I think that it stops on Application.Run() line. Any help
will be very useful.
Thanks for now.

Thanks for the response. What I mean is that it just run the part of the code that is just using the Console, that's the code:
// Main Method
[STAThread]
public static void Main()
clearDatabase(myConnection);
Console.Title = "Suframa Itens Robot";
//If log file exists, it is deleted
if ( File.Exists(@"suframaLog.txt") )
File.Delete(@"suframaLog.txt");
wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(loginWebsite);
try
//It is called as the program uses the WebBrowser Class from Windows Forms namespace
//and it is a console Application
Application.Run();
catch ( Exception ex )
Log(ex.Message);
As you can see, I call a function on start named ClearDatabase, when I call the file from sql server it executes, the tables are cleared, but what I think is that the problem stop when reach the line Application.Run() as it is the line that allows the remaining
code to execute as it uses events from WebBrowser class.
It is a program automation that needs to get a lot of files from a website that needs login and read line by line from the files and put on server, if I call it from the executable it runs fine, the only problem is when calling from SQL Server, Do you know
how to fix this?
Thanks.
