VS 2008 Network App - Send Message Or Network Package To Some Of The Clients In The Network

Aug 18, 2009

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

TCP Listen On Any IP?

Mar 11, 2010

I am trying to make a TCP chat program, but instead of having people enter in the ip of the computer they wish to talk to everytime, i would like the program to be able to listen on all ip addresses, so that it will provide for a better user experience, and that i can have chat rooms with multiple people joining. I have the code working with entering in ips, however, when i use the IPAddress.any command it will not send messages.

Listen For The 'End Sub Event'?

May 26, 2009

This is my first post, so hopefully I'm asking it in the correct place.

Currently I have two subs where the first calls the second.

Sub Sub1()
'some code
Call Sub2(x)
End Sub
Sub Sub2()
'some code
End Sub

This means that Sub1 does not end until after Sub2 is complete.I need to have Sub2 run after Sub1 has ended. In my case Sub1 is triggered from an application event, so calling the two subs from another 'parent' sub would not work.Is there a way that I can listen for the 'End Sub Event' of a sub?I am currently working in VBA but will be heading to .net shortly so I'll take whatever flavour of code people can help with.

Using TCP To Listen For Connections

Dec 17, 2010

I am developing an Application that uses TCP To listen for connections, and then when a message is sent to the server and then it alerts the IP that is running the server. (Lets say the server is on a iPhone, and some how the iPhone gets a text message, which alerts a tcp server running in the background via a .jar, it would send the owner of the iPhone a message on the computer telling it it has a text. This is just an example though, but I think it gets the general idea across. I've been trying to do this, and I can connect to a TCP Server (using 127.0.0.1:8888 for testing purposes, will move to a solid IP and Port later). I can start the server (its still buggy and under development) but i don't know how to connect to the server via an application, and when a certain message is received to alert the IP Running the server.

My Server Code is:
Dim serverSocket As New TcpListener(8888)
Dim clientSocket As TcpClient
Dim infiniteCounter As Integer
Dim counter As Integer
serverSocket.Start()
[Code] .....

Now I know that to connect you'd do something like
Code:
Dim clientSocket As New System.Net.Sockets.TcpClient()
Dim serverStream As NetworkStream
clientSocket.Connect("127.0.0.1", 8888)
serverStream = clientSocket.GetStream()
And I know I would have to use some sort of Byte() method to send/receive messages, but I am at a loss on how to set it all up.

String Or Textbox To Listen?

Mar 21, 2011

I would like to know if it's possible that when an event occurs, a string variable begins to listen (so when a key is pressed, its value is appended to the string) until another event occurs.

EDIT:I would like to make it other way:When the event occurs, I want a textbox to activate as if i double-clicked it (althougt it would be invissible, i olny want the textbox to make an event happen when the text changes using that text)

Get An Object To Listen For Its Property's Event?

Dec 15, 2009

I have an object of type SomeObject, with an event StatusChanged. I have a property in SomeObject of type Status also with an event StatusChanged. Within a private function in SomeObject, I would like to run some logic (including firing the StatusChanged event) in the event that Status has fired its StatusChanged event. I have been away from events for a while so it's a bit cloudy to me. How do I do this?

I'm writing in ASP.NET/VB.NET EDIT Ok, in the event that I can't do the above, how would I get the outer object (SomeObject) to fire its StatusChanged event when the inner object (Status) fires its StatusChanged event?

Listen To Events From A Windows Service?

May 10, 2011

Not surer if I know exactly how to ask or phrase this questions/discussion.I have a windows service that listens to a COM port for GPS data and send the information out through a UDP port to a listening application (VB6 app). I have a UI front end for the service that I would like to listen or watch the data and do some other things with the data.

The service raises an event in which I would like to have my UI listen to. Now I'm guessing that since my UI is on one thread and the service is on another, if I add a handler to the event, it may never pick it up.

Therefore, I am wondering how can I listen to the events from a sperate UI application. I heard a lot about Remoting, but my concern is configuration; our end users are not technical at all and not sure what is involved...and I'm not that familair with Remoting.

Make An Application To Listen In On A UDP Port

Mar 29, 2012

I am trying to make an application to listen in on a UDP port - the issue is that there is something already there. Here is the scenario: On port 5060 is a SIP-based softphone, it is listening for incoming calls. The application I am writing is also listening on port 5060 to receive the packets (which will then be parsed to extract the caller ID and various other statistics)

VS 2008 : DockManager - How To 'listen' To Form MDI Children

Jul 13, 2009

I'm trying to create a MDI DockManager component. Basically what it should do is take each MDI child form and turn it into a TabPage. Instead of showing the MDI forms, the main form then hosts a TabControl with each 'form' as a TabPage.I expect this to be quite a big challenge, and I know I will probably not manage to do it... But it would be a great control if I could!Well, for this to work I need my component to know when an MDI child form is added / removed. As far as I know, there are no events the form throws when this happens... The forms are not added to the Controls collection (are they?!) but the user merely sets the MdiParent property of the child forms.

The only useful event I could find was the MdiChildActivate event, which should fire when an MDI child is activated. I am pretty sure that is not enough for my idea. It might be enough to detect new MDI child forms being added, but if one is closed (eg, removed) there is no way I can detect that.So, I'm basically looking for a way to detect when an MDI child is added or removed from a form. Is that possible at all?

VB Or C# - Run App In System Tray And Listen To Keyboard Input Without App In Focus

Mar 28, 2010

I want to make an app which on loading sits in the system tray and even after I open another program (say notepad or vlc or anything) i.e. even when the app is not in focus and if I press "G" on my keyboard, the tray icon should show a tool tip - "key G is pressed". I have tried several codes but nothing works when the app goes out of focus. I can use Register Hot Key [url] but it needs a modifier also (like Ctrl or Alt etc. along with my key G). So, is there any way I can achieve this? something which many tray icons do like antivirus apps, etc. and I do not want to use AutoHotkey application.

Listen To Recorded Material But Not Necessarily In Real Time - Copy File In Use

Oct 15, 2009

I have an application that continously records audio for several hours. I want to be able to listen to recorded material but not necessarily in real time. I have tried to just copy the file being recorded to a new file with overwrite and the copy obviously gets done (filesize changes) but when I try to listen to the copied file my player just 'blinks' and nothing more happens. If I however close the recording, the copy also gets playable. My idea is that copying a file in use just creates another file in use. If this is the case how can I close the copied file?
