I have two programs running, a client and a server. They are connected through a socket, and a TCPListener. The server is pure VB.NET, but the server needs to take pictures of the desktop, which works, but then needs to send it to the client application.

View 9 RepliesI got a window form, and I want to send data to another computer or a server over internet after the submit button is clicked. Yes, this is a very "general" question (I cant not ask it in more detail), because I don't have any information how to do that, I google it, and I heard WCF, but I am not sure how it actually can do this job (seem like WCF is related, but still researching).
View 4 RepliesI am working on a personal project, and I've been looking at a way to make an application where you can enter in the other user's IP address, load a picture into a picturebox and have it appear in the other user's picturebox, on a separate computer. I am not looking for code, but examples are welcome. I would just like a nudge in the right direction.I've already looked at P2P and winsock, but I cannot figure it out...
View 2 Repliesi wana get property of image like hieght and widht without download image on my pc i wrote some code but it is still slow and doesn't work very well in my program .
i used this code :
DIM IMG_TAGS AS STRING
PictureBox1.Image = New System.Drawing.Bitmap(New IO.MemoryStream(New System.Net.WebClient().DownloadData(textbox1.text)))
[Code].....
Basically I want to have a picturebox which shows an embedded resource if not connected to the internet, and an online image if connected to the internet.I assume this can be done on the form load event, I just don't know the code for it. Basically this is the logic though:
-If 'http:/[url].... is available (therefore connected to internet)
-Picturebox1.Image = http:[url].....
-Else[code].....
How can I code that properly? Would putting it in the form load event work?
Ok the other day I saw a neat little DLL that grabbed an image of the internet depending on what the user enters it was used like dllname.Whatever(String, PictureBox1) now the thing is Picturebox was was just that you just Put it on your form and called the dll with that does any one know how to do this

View 1 RepliesI'm writing a Cleint/Host program that sends a image over tcp (from printscreen, not a file) to the host. Everything seems to work fine and the image is transmitted and displayed in a picturebox plus saved to a folder. The problem is when the printscreen is bigger than 176040 B. First the limit was 128000B but after setting the sendbuffersize and recivebuffersize to 1000kb the limit is 176040 B. Could it be a limit in the tcp protocol?

I am writing a VB.Net application wherein I would like to be able to communicate with it from a remote computer. Specifically, I would like to be able to send (from a remote computer) both text data and also images (jpg, png, etc.) and then have the application use the sent information by displaying it to the user. How would I code the VB.Net app to be able to handle incoming data like this?
If possible I'd like to not be dependent on .Net technology on the "sending" side so I'm not sure if I would just use sockets or a web service or what.
I was wondering if there is an easy and fast way to send an image (or files in general) which is small, as in around 30KB, over the network using VB .NET. the most i was able to do at one point is to read the image (or file) as text, then send each character over the network, but it took way too much time for the file to get sent, and then translated from text to file once again on the other side. I don't know much about network programming, because i just started learning about the subject.
View 3 RepliesIm trying to send an image from the server to the client by using network stream. I have looked on google and found out that you can use memory stream and send it, but how do I use memory stream to get the image from the stream and display it on a picture box on the client side?
View 5 RepliesI 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'm currently patching an asp.net program where I need to be able to send an image to an SQL Server 2005 DB. It works fine when I use the asp:fileupload control, but the trick is that when the user deletes the image, I'm supposed to replace it with an image from the server saying "empty", in code-behind. I know how to open, use and save text files in vb, but I can't find any information anywhere on how to open an image / binary file in a similar manner so that I can use it as an sql-parameter on the update query. Below is an example of how easy it is to use a file from the fileupload control.

I would like to ask about sending an image file through serial port to a external embedded processor....
the way i think i want to do it is that i would like to open the image file in VB.NET as a binary file and then
1)either converting this binary file to a text file and then read the content of that text file to sent it through UART to that external processor or
2)Converting the binary file into an array and send that array through uart.[code]...
