What code can I use to send a simple text file to someone else's computer and choosing a save location and vice versa from theirs and loading it into a rich text box in their application that they have open, and vice versa? Their application is the same as mine (sort of like how an instant messenger works-except it does not save, send, and load text files like I am aiming for)
View 3 RepliesI am trying to make an app which can send/receive files/pictures. I am trying to make a app which will get a picture of the users screen and send it to me, and display it in a picturebox at a set interval. With this, I will be able to sort of see what someone is looking at without having to have him send screenshots constantly.
Remote assistance does not seem to work for these apps, shows black, but I can make the program already get an accurate screenshot and display it of this program, I just need to know how to make it send it to me and display it to picturebox.
The thing I have been using is the MultiUser TCP chat application off MSDN's website, I don't know if this will work, but I need to make it send somehow and display it.
I'm working on a network chat for my office I want to add a way for users to share files or be able to send and receive file.
View 7 RepliesI've solved part of the problem, but something I've just realised is the information just isn't getting through and EVERY example I find uses a Console type application and what about us people who don't wanna develop a Console application? I don't but nooooo they don't seem to understand that at MS and put one example which uses exactly that.

Normally with webpages you can read and write a file very easy but i've never done this withSo far the read code works. write code works in local mode, the only thing is he won't write to an online file.i don't get any errors the code looks fine for the debugger.the code so far (local mode for testing)

Instead of the send message text box and message display text box, I have replaced it with RichTextBox for text formatting (bold/italics/underline/font/color). The problem I am facing is when I format the text and click on send, then the text displayed on the message display box (txtMessageHistory) is unformatted. [Code] Rest of the code of client is related to formatting of the rich text boxes that is not relevant to my problem. I just need to transfer the formatted text from client to server and then back to the client the same way and display the message with text formatting.

View 3 RepliesSo ive looked everywhere but every example i find doesnt work on visual studio 05 and doesnt convert properly. I simply want to send info from one computer to another through direct connection. if anyone could point me in the right direction it would really be helpful. most stuff i find seems to be more complicated than what im looking for.
then just one other question. both computers will be going through a router. as long as i have the port im using forwarded on the hosts side, that shouldnt be a problem, right?
Since a few months I want to learn how to receive and send packets. Since WinSock doesn't work I think it'll be quite hard to get an easy way to do it.
I want to be able to send and get packets as a client. (TCP) I know that I need System.Net.Sockets, and that's quite everything...
I was going over the Screen Saver Tutorial for VB Express 2005 and i Noticed How the Screen Saver app excepts params at startup... and depending on the startup param it will display the screen saver or the options form... lets say that i want to start up a screen saver from my program, how would i send it to the screen saver to display the options form the param is "/p" or something.

View 1 RepliesI'm thinking about how I'm going to connect a computer to a projector and I came to think if it is possible to send a live stream of a computers screen to another computer via for example TCP or some other protocol. It must be possible since for example TeamViewer and other long-distance IT-support applications can do this. The thing is that I dont have a clue about where to start. And is it difficult to output the stream once it's recieved?

I need to send and receive a large image between programs running on different machines within the same network.
I've looked at using upd however ran into problems with the size of the packets and
(after breaking the image into smaller pieces to get past this problem) the number of packets needing to be processed all at once - and ultimately packet loss.
I've also thought of sending the image by storing it in a common file folder and receiving it by using file watcher as a trigger. However, this just adds further complexities in setup where common folders don't already exist.
Assuming I'm barking up the right tree looking at tcp, can someone point me to/provide an example of how to send an image file using it (vb.net would be ideal). Also, are there practical limits to tcp package sizes?
I have these following lines to send bytes using socket
Dim server As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
Dim myIp As IPAddress = IPAddress.Parse("myIP")

I'm using asynchronous to send/receive from a website I want to block the BeginGetRequestStream method which I have done, using
Code:
WaitEvent.WaitOne(1000 * 20, false);
the problem is that it blocks the UI, which I thought it did not so it basically works like GetRequestStream which does block the UI.
Do you know how to create a program to send and receive sms and call from PC from and or to any devices?
View 1 RepliesI have created an application which listens for strings being sent to my pc from a remote unit. I now need to add the function of sending strings back to the remote unit on a button press. I've searched for ages to find a solution but I'm not knowledgeable enough yet with vb.net to solve this solution.
I'm getting the error with the line opensock2 = New IO.StreamWriter(client.GetStream) saying its not connected. So I seem to need to pass the connection from the background worker to the button click, or have it somewhere else in the code to make it accessible. [Code]
as above how to do that man? I will also want to extract the information to be sent from the database. An example of what i am going to do is something like this:
Reference:[URL]..
I didn't found any performance counter that would monitor an process's/thread's network bandwidth and not just that of an ethernet card.
So I could see how much bytes did an application receive and send.
Did I miss something or is there another way?

Now i need to do a few hundred/thousand requests all at the same time or atleast over a short period. I am assuning i need to do this asynchronously. I have looked all over the net and tested various ways to communicate asynchronously and am pretty stumped. None of the examples out there seem to explain how i receive the xml return as a string ("which i will write to file or db")
Does anyone have any working code to do such a process?

I coded a small tcp server/client software implementing the async methods of the socket object. In order to keep track and control of the transfered data on both sides, I decided to wrap the bytes to be transfered into small 65 000 bytes packets, sent one after each other, in varying order.In most cases, it works perfectly, and it is impressively fast. However, when I want to transfer larger data than my usual requests, say like a dozen megabytes, crippling problems start to appear, out of shit.Effectively, it seems that somehow when executed without pauses, the server sends the packets too fast, or that the client receives it too slowly. However, if I put the SendAsync method's thread to sleep for like 100ms before sendingthe next packet, everything arrives without problem on the client.[code]
