Chat / IM

Instant messaging (IM) is a type of online chat that offers real-time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non-IM types of chat include multicast transmission, usually referred to as "chat rooms". Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (a central server retransmits messages from the sender to the communication device).

I need help for a java assignment. I'm trying to use the jOptionPane to input a number but I need to check if only numbers were entered. At the bottom of this code at //check if only numbers were entered, you can see what I have so far (It's just an Idea that didn't work out)

Any help is appreciated, I have until 10:50pm (currently 11:23 am) to get this done along with some other stuff related to overloading.

here's the code

public class Lab5Start {
      private static String input;
      public static void main(String[] args) {
            //Enter grade for 4 students through JOptionPane
            int grade1 = Integer.parseInt(JOptionPane.showInputDialog("Enter Student 1's Grade"));
            int grade2 = Integer.parseInt(JOptionPane.showInputDialog("Enter Student 2's Grade"));
            int grade3 = Integer.parseInt(JOptionPane.showInputDialog("Enter Student 3's Grade"));
            int grade4 = Integer.parseInt(JOptionPane.showInputDialog("Enter Student 4's Grade"));
            //create a Jframe_for viewing results and messages
            JFrame frame = new JFrame();
            //check if only numbers were entered for grade
            if (Integer.parseInt( "^.*[a-zA-Z].*$")){
                  System.out.println("Please enter numbers only!");

Hi there fellow Tech Community,

We are having a few issues in our organization whereby some users are not receiving new emails unless Outlook is restarted, when you restart Outlook, it delivers new messages and does so for say under a minute, then stops delivering new messages.

Here are some of the troubleshooting steps we have carried-out, we are finding that the only way to overcome this, is to rebuild the customers PC, which as you all know is a cumbersome task and shouldn't be necessary to resolve an Outlook issue;

-Office 2016, 32 and 64-Bit
-Windows 10, build version 1607, 1703 and 1709
-All laptop users (HP EliteBook 840 G3 and Lenovo T440p)
-Windows Updates pushed out via WSUS

Troubleshooting done;
-Ran repair of office
-Recreated local OST Files
-Recreated Outlook Profile
-Recreated local Windows Profile
-Checked Outlook connection status, all showing as connected
-Checked A/D Account, not locked or anything along those lines
-Ran scan pst tool, that not really applicable anymore with Office 2016

Some more background;
-Users have additional mailboxes in their Outlook, some are manually mapped in Account Settings, some are delegation mapped via Exchange Admin Console
-We have a mixture of users on Android and iOS devices synching their Exchange Account, does not appear to be a trend with mobile devices

If I have missed any further details, I'll add them, other than that, any suggestions and what people have …
  • I write an email from the Boss and click send.
  • Because of my email delay rule (see picture below), it goes to the outbox. Because of importance, I check it in outbox and then resend
  • The act of checking in the outbox makes the messages switch to my account, not the Boss'ss. Because I *know* I’ve already sent it from his, I don’t think to check this bit.
  • Because it was originally sent from the Boss's it is in his outbox, it still appears in his sent folders when it eventually sends, even though it has flipped to come from me.

Here is a screenshot of my email delay rule.

Outlook Delay Rule
We have a client who is using Skype (not Skype for Business) and is in a couple groups chats.  On a daily basis, there are messages that are received in Skype on their phone, but the messages do not show in Skype on their computer.  Some of the messages that are received on their phone do appear in Skype on the computer, but not all of them.  Is there any way to synchronize the messages between Skype on their phone and their computer so that all messages show on both.
I have a client who has a POP3 account in Microsoft Outlook 2016 Professional Plus.  When I try to change his account settings, going to More Settings then Advanced, the default delivery is "Leave a Copy of Messages on the Server" and "Remove from Server After 14 days".  Both of these items are checked.  I have went into this account and tried to take the checks off of both of these boxes as the user doesn't want messages saved to the server.  I can uncheck the boxes and click OK.  It takes me back to the prior screen of which I click on "Next".  A window pops up showing that Microsoft Outlook quit working and then subsequently closes Outlook.  You then launch Outlook again, but the settings are checked again.  Is there a way to get this permanently modified?
When I use The Microsoft Connectivity Analyzer for Skype for business connectivity I get an error when it is attempting to obtain the SSL certificate from remote server. please see attached.
 I am looking for the chatting software that meets the following requirements:

 (1) It should run on Windows, Mac and Smart phones.
 (2) Only inter-office users would be allowed to use  the app. Skype would be a good fit except users can include/invite anyone in the world who runs Skype.
 (3) When the message is arrived, it will popup in a window or provide an alert with audible sound.
 (4) Fyi, there is Outlook with Exchange already for the users. The reason for this chatting app is to let the users chat with other users on trivial stuff that don't need to be saved in Outlook/Exchange server.

 I welcome commercial software as well.
Our client often gets complaint's from their customers not being able to send attachments through to them because they continuously get rejected for being too large.

They're using an on-prem 2010 Exchange server.  
The initial message size limit send/receive was set to 30MB.
Their hosted anti-spam solution, Trend micro, has a limit set for 50MB.
I changed the on-prem 2010 Exchange server send/receive to a limit of 50MB for troubleshooting purposes.

We still get bounce backs when sending anything typically over the size limit of 15MB. The message comes back indicating it exceeds the limit of 20MB.  After checking all the settings (that I know of), I don't know where the size limit of 20MB is being set.  I know that messages grow in size beyond the initial attachment limit, but not to this degree.

Is there anything specifically I've missed in checking?

Thank you!
Voicemail using Unified Messageing and Skype for Business - Greetings not being played/ applied correctly.

Afternoon everyone,

We use Skype for business, for VM we use Unified Messaging and whilst this technically works I have unearthed an issue with greetings.
Due to the nature of our business we need to have two different greetings for in and out of hours (simple one would have thought). We have these two greetings recorded in the system and can hear them when we go to re record.

However, when the number in question is dialed and goes to VM all we get is the generic 'Welcome to the mailbox of' message.

I've played with rules and settings through OWA and cannot figure out what I am doing wrong.

Happy to share settings or anything if it helps diagnose.

Can I use the Telegram Bot API for listetning to message on a private invite-only channel?

Background information:
I was hired to do a gig for doing a Telegram bot that could parse messages and saved them into plain text. Now, I was told that the bot is required to listen to message in invite-only  channels. While doing some research, looks like this is a bit of an issue. I heard some suggest to use the Telegram Client API (instead of Bot), can someone confirm this is possible on the Bot API, or if I actually ave to switch towards Client?

Hi guys,

I want to ask - somehow, recently i lost all my emails in my Apple Mac laptop. I used Micro Outlook (apple). I went and opened Outlook on my apple and i cannot remember what i must have done. But anyway, the outlook is emptied and i cannot see all my messages.

However, i can locate the main identity where i believe all the database and messages of my Outlook at this location: Documents/Microsoft User Data/Office 2011 Identities)

Please can someone advise me steps on how to restore all my emails into Outlook again so that it work the same structure to before?

There is a way.

Please would appreciate the help and steps?

I'm using Skype For Business 16.13.184 on Mac OS 10.13.2

We are testing out Skype for Business with our Office 365 Business Premium license and the first thing I noticed is I cannot paste an Image from the clipboard into the chat. I can Attach an Image, but thats more work if I'm sending screen shots.   Seems to work on Windows.
I was using Python 2.5 but just downloaded 2.7.14.  I just got the error: ImportError: No module named numpy.

And, how do I search solutions - I found lots of others with error messages similar to mine (exactly except for numpy), but found no answers.  

Thank you!

Does anyone know of a way to be able to transfer Messages from iphone 6 to 7.  The owner started the new phone (the 7) and skipped past the Setup where you can put the old phone near new and import everything.

We have since set the iPhone7 up and everything is done but the Messages history.

I have looked for Apps but cannot seem to find one to backup old phone and restore to new.  There are even Apps where you need to have that App as the Messages app.  I don't want that.

if anyone has experience with an App it would be great to know.  Or if you know a free way of doing it.
