s!mpL3 LAN Messenger

[AoRaToS]

s!mpL3 LAN Messenger as the name suggests is a messenger designed and developed to offer chat communication over Local Area Networks while being as simple to use as possible. This project started way back in 2008 with only basic functionality and is regularly updated with new features in order to make it more useful and user friendly. What I wanted was a simple, small, serverless program that would work without installation cause that was the ideal combination for my workplace back then, so I ended up with this!

I have attached some images from various versions:

Check the rest below! (from various versions)

More than 10.000 downloads!

s!mpL3 LAN Messenger version 2.9.9.1 - [04/07/2019] - s!mpL3 LAN Messenger.zip

1. Fixed an issue that would occur when blocking another user and they would re-appear in the TreeView.

2. Updated File Transfers to make long file names shorter if they were too long to appear in the tray tip.

3. Removed notifications when checking for updates at application startup if there is no update available.

You can view/download the full change log here: ChangeLog.txt

Tested and working on both 32bit and 64 bit editions of Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10.


Things you need to know before trying it:

1. Start the program, select one or more connections from what's available and click Connect (If a firewall notice comes up, click 'Allow' or 'Add Exception')
When someone else on your network does the same, they will appear in your Tree-view and you will appear in theirs, double click their name and chat!

2. s!mpL3 LAN Messenger does not require a server to be running, it's standalone.

3. On the first run an .ini file is created at @LocalAppDataDir\s!mpL3 LAN Messenger which stores the settings so that they are used every time you run the application. If you delete the .ini file it will be created again (with default settings at program startup or with your selected settings if you press Save from the Preferences window).

4. All communication is encrypted using AES so it's quite secure against Network sniffers.

5. You can send files and folders by dragging and dropping them in a conversation window. Folders are compressed before being sent. You can also drop multiple items to be sent.

6. There is a "Hide" button located in the tray right click context menu that will hide all open windows. You can assign a Hotkey combination from Preferences. The default combination is Ctrl+H.

7. s!mpL3 LAN Messenger uses port 60000 by default. You can change the port used by adding "Port=****" (without quotes, stars represent numbers) to the Config file described above. Communication is UDP.

8. There is an Updater feature you can use to always have the latest available version, you only need an internet connection for that to work. You might need to clear your Internet Explorer Temporary Files in order for it to find an updated version.

9. You can Hide + Lock s!mpL3 LAN Messenger so it'll require a password in order to "Appear". To enable this, go to the Security Preferences.

10. Note that versions after 2.9.8.1 are not compatible with previous versions due to the encryption used being changed. I recommend using the latest version, or at least use the same version over the LAN.


Important Notice:

I will not be releasing the source code, however, I might share some parts of code if requested...
If you choose to de-compile this software, don't release the source code.

I am working on something very similar, but am not nearly as far as you are. Any chance you will be releasing the source? If not, no worries and keep up the good work.

I tried this with my brother. Everytime I hovered over his name.. a tooltip came up,. Regardless, when I attempted to double click (beating the tooltip showing up), nothing would happen.

[AoRaToS]

Thanks for your feedback!I won't release the source code yet but I will gladly help if you need anything with your script and I can give some parts of the code if requested...

Javascript_Freek I fixed the tooltip part, It's supossed to NOT show now so it will probably work fine for you now, I had that problem in the past on some computers and I thought I'd fixed it...I've changed the attached file to the corrected one, if anyone has any other problems let me know!

Also, I haven't tried this on Windows Vista so I don't know if it'll work... I've used it on Windows XP Professional SP2 and SP3...

Maybe it's cause I'm on Windows Vista!

I shall let you back with my info on the new version.

[AoRaToS]

New version released!! Some stuff added, check it out on the first post of this topic

[AoRaToS]

I have changed the attached file, it's now version 2.4

FIXED

Clears the list from clients that may close the program by not using File -> Exit or their network connection has a problem(Every 5 mins. In the next version it will be in the options to choose)

ADDED:

A handy view of which networks you are connected to, what IP's you have and how many users are connected on each of those networks.

Many more things to be added soon...

I found a bug with the network view when connected to more than one network, also something I'd forgotten about in the duplicate Username check so now it reacts as it should. Same version number. I just changed the attached file with the errors corrected so GRAB It. Version will only change if I add/improve a few important things.

[AoRaToS]

New bug found and corrected.

Bug: When you had open conversation windows and the user you were talking to disconnected, if you "HIDE" those windows wouldn't hide, now they do, works for chat windows also. Same happened if you had the program "HIDDEN" and someone sent you something and disconnected then if you "UNHIDE" you wouldn't get what was sent.

Also added a notification when you press disconnect and have open conversation windows, if you press yes the windows will close and you will be disconnected.If you press no the notification will close, the windows will stay open and you won't be disconnected.

I will also add an option to close that notification and have a default action set for it.(Later version)

I have updated the attachment. Many minor bugs fixed.

Next version will be a major release, not a BETA, with Options fixed and more...

Very Nice program, works like a charm in Vista x84.

[AoRaToS]

Glad you like it!!

It's an ongoing project so there is much more to come...!

[i believe you mean Vista x86]

[i believe you mean Vista x86]

Yeah that too

[AoRaToS]

I thought of some bug that probably exists and just tested it, I was right but I don't have the code available at the moment, not until I go home later, so I'll fix it then and update the attachment. Be sure to download it and use that instead of the one you have now cause this bug can make LAN Talk crash, so someone on your network can lead everyone to a LAN Talk crash...

[EDIT]: Also removed the attachment so that noone else gets the bugged version.

Stay tuned for the update...

Ok I have updated the attachment in the first post!!!

It's version 2.6 now.

The Bug was in the Username, I'd forgotten to limit the use of ":" and blanks. Use of ":" in the username would lead to a crash If you sent anything to anyone and to everyone at once if it was a chat message.

Use of blanks in the username wouldn't create any problem but it is annoying some times...

I have updated the attachment with version 2.7!

Check out the options... I have fixed them a bit, some are still under construction and more are on the way.

In options menu:

1. Start with windows doesn't work yet

2. Username doesn't work yet

3. Auto-refresh time doesn't work yet

The rest do work but still need tweaking and some changes, still haven't decided about all the options...

[AoRaToS]

Version 2.8

1. Effects removed for now, if you want them let me know!All other options fully working. (Start with Windows, Auto connect, Change username, Auto-refresh time)

2. Also added some extra functionality to make the program more aware, so If there is a connection change (network adapter disabled, connection to a new network, IP change etc) any change will be shown. If you are not connected and there is an IP change, the new IP will change in the Connections Box, If a network adapter is disconnected it will be shown there. If those changes happen while you are connected you will be notified. The program checks for changes at every automatic refresh when you are connected.

The best setting for automatic refresh is probably any setting above 10 seconds, you can set it lower but note that for the about 100ms - 500ms that it takes to complete receiving other messages will be paused. I use a 1 minute delay and sometimes 5 minutes.

3. Different compressor used which compresses the .exe further so it's smaller in size. For UPX version please contact me
