Sending a message from a webpage to an app(lication) on the user PC

I want to be able to send a stream of data from a user computer to a web-service. That should not be too hard - I would not use asp.net for this, but I would use an application written in dot-net that resides on a user computer.
However, the tricky part is that the stream-of-data should only be sent when the user clicks on a button or a link in a WEB PAGE. And he should be able to stop the stream by clicking on a stop-button (or link) in that web page..
So I found some info on 'stackoverflow' that says that you can put a link in your page, something like: [a href='alert:"Hello World" ' ] and if you register your application (in this example the app would be called "alert.exe") in
the registry, then when the user clicks on the link, he will cause the application to start, and to receive "Hello World" as a parameter.
Anyway, there are complications in my case. I want to be able to tell the application when to start sending data, and when to stop sending data, without starting new instances of the application. If the user clicks START, and the app is already
open, I don't want it to open again. I do want a message to go saying "start sending" and if the user clicks on a STOP button (or link) to say "stop sending". The user might click on these buttons several times in a session,
and I don't want to close and reopen the program each time.
So in general, am I taking the right approach? Would "plug-ins" be a better idea? If I am taking the correct approach, is there some way to send commands from a web page to an application?
And is it safe to have my app modify the registry of user computers? If so, is there a set of commands for doing that? Is the registry supported by Windows 7, Windows 8, etc? I know it is not supported on a Mac.
Thanks in advance.

P.S. (the info on launching apps from your browser was at: http://msdn.microsoft.com/en-us/library/ie/aa767914%28v=vs.85%29.aspx).

Why not using ASP?
If on your webpage you have some buttons that runs at server, the server can create a web Client and using your IP address retrieved from the cession, communicate with your application (that will act as web Server).
then the web client on the web server can send request to your VB application and read a stream as response.
This web client being control by the buttons on the web page, gives you complete control over what and when the data is sent
This way you will have a complete control over the VB application from the web page.
I am not saying that the way you want to do it cannot work, ... but it seems more complicated

Regarding text messaging, if I send a message from my iPhone, the reply goes to my ipad, or mini ipad. How can I stop this from happening?

Go to Settings/ Messaging/ Send & Receive on each device to set the contact points to be reached at, and to set the "from" address when you start a new message. It sounds like your iPhone might be sending messages out as one thing (e.g. an iCloud address) but set to not receive replies only to your phone number. Make sure you review settings on each device since you may, or may not, want to have them common.

How can I send a message from database to a J2EE application?

How can I send a message from database to a J2EE application?
If I have a codetable in database that has new or modified values I have to refresh the codetable in my J2EE application.
Most effective way would be send a message to initiate a table reload from J2EE app, but I don't know how to do this.
Now I have a background thread that regular reads the table and looks for changes.

http://www.oracle.com/technology/products/integration/bam/10.1.3/TechNotes/TechNote_BAM_AQ_Configuration.pdf
This document details how to create triggers on a table that send out JMS messages.
In this example, the messages are going to Oracle BAM.. your message could go to your J2EE application listening to its own topic/queue.
an alternative idea.
you could also just cache your lookup table with something like Oracle Coherence and than try to ensure that all changes to the lookup go through Coherence, so that you won't need to do notification from the db up to the application. the application and the lookup data management tool would be using the data grid for management of the lookup table data, and the data grid (coherence) would persist the lookup data changes back to the db.

You need to link your iPhone number to Messages - and Facetime if you use it. For Messages go to Settings>Messages>Send and Receive at>You can be reached by iMessage at. If your phone number is showing there, select it as your Contact address. If it doesn't appear in there, take a look at the end of this article for help.

How to send JMS message from pl/SQL to jBoss

Hi all,
I need a helping. This is my problem:
There's a queue which is definitied under the Jboss. I would like send a message from pl/SQL to jBoss.
Why is't working??
http://www.oracle.com/technology/sample_code/tech/java/jsp/samples/jms/Readme.html
thnk's,
fgy,,

You can defince a queue in Oracle, then access this queue from your Jboss application. Not sure if you need JMS, but there are some Oracle OCI functions that are certainly helpful for such a task.
You might look into further details be reading the manual on Oracle Advanced Queuing or Oracle Streams.

How to send JMS Message from a BPM Process

Hi All
I have small query regarding sending JMS Message from a bpm process. Is it possible to send JMS message from one bpm process to another bpm process.
I have a scenario in which I need to send a JMS message to a queue where another process is listening on that queue and as soon as the message is received on the queue the process instance is created.
I know how to listen for the JMS message on the queue, but I don't how to send a JMS message from a process.
Also Can I create process by sending the Notification to the process instead of a JMS message. But the process to be created is not a subprocess i.e. Can notification be send accross different processes.
Any information or example in this regard would be helpful.
Thanks in advance

Hi,
Here's one approach to sending JMS messages from an Oracle BPM process. If you're doing this just to send a message into another process, do not take this approach. It's far easier and quicker if you do this using the OOTB "send notification" logic.
These steps describe how to do this using WebLogic. The steps would be different if you're using another ap server / JMS provider.
1. Guessing you've already done this, but first expose the two required WebLogic jar files for JMS messaging as Java components in the External Resources. The two files for WebLogic are weblogic.jar and wljmsclient.jar” (located in the < WebLogic home directory > /weblogic/server/lib” directory).
AquaLogic BPM JMS Queue Listener for WebLogic 8.1
2. You've probably already done this, but add an External Resource to represent the J2EE container:
• Name: “weblogicJ2EE” - this is important and will be used in the next step
• Supported Type: “GENERIC_J2EE”
• Initial Context Factory: “weblogic.jndi.WLInitialContextFactory”
• URL: “t3://localhost:7001”
• Principal: and Credentials: whatever userid and password you defined to access theWebLogic administrative console.
3. Create the External Resource that represents the send queue configuration. In this example, I'm calling it “WebLogic Send Queue”. This is important - remember what you named it because you will use this name in the logic that sends the JMS message. This new External Resource is configured as:
• J2EE: “weblogicJ2EE” (same name as the second External Resource you created)
• Destination Type: “QUEUE”
• Lookup Name: “weblogic.examples.jms.exampleQueue”
• Connection Factory Lookup Name: “weblogic.examples.jms.QueueConnectionFactory”
4. Here's the logic to send a Message to the Queue
<pre class="jive-pre"><p />msg as String = "Hello World"
jmsMsg as Fuego.Msg.JmsMessage
msg = "<?xml version=\"1.0\"?><Msg>" + msg + "</Msg></xml>"
jmsMsg = JmsMessage(type : JmsMessageType.TEXT)
jmsMsg.textValue = msg
sendMessage DynamicJMS
using configuration = "WebLogic Send Queue",
message = jmsMsg</pre>
Note that the “sendMessage” method uses the configuration parameter “WebLogic Send Queue”. You previously created a JMS messaging service External Resource with this name in the third step.
Again, please don't go this route if you're just using it to send notifications between processes,
Dan

Send a message from a list of emails in lightswitch 2013.4 HTML screen using ajax

Hi There,
any idea how to make a button to send a message from a list of emails in lightswitch 2013.4 HTML.
my idea is to send message to all emails in the details picker (or the drop down menu or a choice list) tat is filled by SQL query (as a data source in lightswitch)
i have read many articles, most of them were written in PHP or VB !
for example:

as far as i know, the HTML screens in lightswitch 2013 can be encoded with ajax only, not vb or C# any more!
my project contains only HTML screens, no desktop screens. i know that i can do the VB programming in the tables actions, but i am looking to have this code in the Browse screen to give me more flexibility depending on my decision to
send or not..
help please :)

Hello Hasan,
I do this using a generic handler(e.g. sendmail.ashx). In the ashx file i use this code:
Imports System.Net.Mail
Imports System.Web
Imports System.Web.Services
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim str As String = "there was no error "
Dim Recipient As String = Convert.ToString(context.Request.Params("pRecipient"))
Dim strsub As String = Convert.ToString(context.Request.Params("pSubject"))
Dim strmsg As String = Convert.ToString(context.Request.Params("pMessage"))
Dim msg As New MailMessage
Try
' Your mail address and display name.
' This what will appear on the From field.
' If you used another credentials to access
' the SMTP server, the mail message would be
' sent from the mail specified in the From
' field on behalf of the real sender.
msg.From = New MailAddress("[email protected]", "Displayname")
' To addresses
msg.To.Add("[email protected]")
'msg.To.Add(New MailAddress("[email protected]", "Friend B"))
' You can specify CC and BCC addresses also
' Set to high priority
msg.Priority = MailPriority.High
msg.Subject = strsub
' You can specify a plain text or HTML contents
msg.IsBodyHtml = True
msg.Body = strmsg
'msg.Body = _
' "Hello everybody,<br /><br />" & _
' "I found an interesting site called <a href=""http:'JustLikeAMagic.WordPress.com"">" & _
' "Just Like a Magic</a>. Be sure to visit it soon."
' In order for the mail client to interpret message
' body correctly, we mark the body as HTML
' because we set the body to HTML contents.
' Attaching some data
' msg.Attachments.Add(New Attachment("D:\Site.lnk"))
' Connecting to the server and configuring it
Dim client As New SmtpClient()
client.Host = "mail.gmx.com"
client.Port = 25
client.EnableSsl = True
' The server requires user's credentials
' not the default credentials
client.UseDefaultCredentials = False
' Provide your credentials
client.Credentials = New System.Net.NetworkCredential("yourcredentias", "f2f081639ad")
client.DeliveryMethod = SmtpDeliveryMethod.Network
' Use SendAsync to send the message asynchronously
client.Send(msg)
Catch ex As Exception
str = ex.Message
Finally
msg.Dispose()
End Try
context.Response.ContentType = "text/plain"
context.Response.Write(str)
End Sub
When you create the ASHX then replace the ProcessRequest with the above function.
In LS HTML Screen create the function for pressing a button an appen the following text:
$.ajax({
type: 'post',
data: {
pRecipient: Screen.yourdata,
pSubject: Screen.yourdata,
pMessage: Screen.yourdata,
url: '../sendmail.ashx',
success: function success(result) {
alert(result);
This is a way you can do that. In VB and out of your browse Screen.
Hope this helps

How to send JMS message from oracle to weblogic

Hello,
I am facing with a problem of sending jms message from oracle to weblogic. I am using oracle 10g and weblogic server 9.1. Here is the problem. I would like to create a trigger to send JMS message to weblogic server whenever there is an update in oracle database. So I created a java class that will send a jms message to weblogic server. But in that class I use the jndi from weblogic: weblogic.jndi.WLInitialContextFactory
when I use the loadjava utility to load that class into oracle, the status of that class is invalid though this class is working fine in eclipse with the weblogic.jar included. I was thinking because the jndi from weblogic needs the weblogic.jar in order to work, then I loaded that jar file into oracle (it took about 20 minute to load everything) and everything loaded into oracle from that jar file is invalid and missing some reference.
So my question is: how do I send a jms message from oracle to weblogic using a java class with the right jndi?
Any help will be appreciated.
Thanks
TL

It should be quite straightforward to do this. As stated you need weblogic.jar in your classpath, then use 100% standard JMS calls to publish.
Ensure that you set the following properties before getting your initial context:
java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
java.naming.provider.url=t3://node:7001 (or whatever)
this will ensure that the correct JMS implementation classes are invoked.
You can't easily (without some mucking around) build a test implementation in an AQ environment and then deploy to WebLogic because in AQ you don't tend to use JNDI lookups (unless you've implemented oracle JNDI etc) but rather use non standard factory class to create connections etc.

Can't send audio messages from Nokia E63 to email ...

I used to send audio messages from my mobile to my friend's email, and it worked fine.
But some days ago it stopped working. I keep on seeing this whenever I try to send audio message.
"In order to send/download MM messages, the current active connection may be closed (this may affect other applications in use). Do you want to continue ?"
When I disconnected connection, it fails to send again. I saw this message:
"Multimedia message cannot be sent. Packet data connection not available"
It is impossible for me to send the audio message if I close the connection because I'm not having internet in my phone.
I have been using packet data connection to send all the messages to email all the time and it went OK. I got that problem just a few days ago and I cannot send any audio messages now.
I can still send normal emails (non-audio message) from my phone through packet data connection though.
The problem is only when sending the audio message.
I'm using Nokia E63 and I'm in the UAE.
My mobile provider is "Du".
I use packet data connection from "MyWorld"
I don't have any other packet data connections. I had many but now, MyWorld is the only one in my phone.
Please help me how can I do it.

Automatic configuration.
Your mobile will be automatically configured to access the MyWorld mobile portal when you first join du.
You will receive an SMS message, which you should accept and save.
You can also request for these settings by sending the following SMS message “du” to 333 or by calling Customer Care on 155.
Availability of the MyWorld mobile portal and of the relevant settings is dependent on your handset type.
For more information on MyWorld, call 155 from your mobile or visit us at www.du.ae
This might do the trick.

hi,
SMS API(WMA) is an optional package. It is not a MIDP1.0 or MIDP2.0 api's.
There are phones which has WMA api with MIDP1.0 support .... Nokia 3650
Seimens has some phone with their own api's to send sms.Check out seimens site for more info
BTW, What do you mean buy sending SMS to Server????
If you want to send message to server you can do it with Http.

Sending 2 messages from SAP but get 1 message in PI

Hi all,
This is a bit of a strange one but I have the situation where we send two idocs at the same time from a SAP ECC system to PI. The first idoc is processed but the second one just dissapears. Things I have checked:
SMQ1/SMQ2 on both systems - nothing there
Runtime workbench - the successful one is there but no failed messages
Sending two messages from another ECC system - we do get both messages - but this is a different interface (however the one with the problem is just a copy of the one which works)
Any ideas what this could be or what else I should be checking?
Kind regards
Ben

Hi Mark,
Thanks for your quick reply. I have checked idx5 and there is only one message/TID from the sending system.
The other ECC system is owned by a different department so I will ask them to run SM58 to see if anything is stuck in there as well
