I'm trying to send an image to Imgur's server.Everything went fine and I'm getting the URL of the image from the parser but when I'm trying to open it on the web browser, I'm not getting the image... only a "broken image" icon.I think it's a problem in the convertion to the byte array.... but I don't get it.
Dim image As Image = image.FromFile(OpenFile.FileName)
Dim ms As New MemoryStream()
' Convert Image to byte[]
image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
I want to send a image file from server to client?i am using this code for sending but i can't send the image....... and i also need some receiving code.
1.Public Sub SendImage(ByVal sndImg As String) 2.Try 3.Dim ns As System.Net.Sockets.NetworkStream 4.Dim client As System.Net.Sockets.TcpClient
Are there any good books out there that will show someone how to set up a form using Visual basic that will take information and send it to the server and then send a recipient an Email?
i'm tying to send email in my application directly by the smtp server but the server doesn't allow me to do that.The application its used by everyone in the company, so i set the smtp client UseDefaultCredentials to True, but the server replies with this when i try to send an email:[code].....If i set the credentials by hand, the server sends the email. So my problem is how to make this work to everyone? I don't want to have one public/friend var all time in the application with the credentials of the current user?
I'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?
Here's the client code
Code:Imports System.NetImports System.Net.SocketsImports System.IOImports System.DrawingImports System.Drawing.Imaging Public Class capture
I have a client/server application set up that the client sends a word file to the server and then the server converts that word file to a .TIF and sends the image back.The stuff I have now works.Say if I sent the size of the file and the actual file byte() to the server back to back, would the NetworkStream contain both back to back? This what I though would happen. So I implemented a kind of 'turn' based interaction during the duration of the conversion process.
how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])
Hey guys, I am trying to send data from client to server (encrypted) and the string sent from the client is not the same as recieved from the server. I've been killing my brain for hours to get this to work but I cant manage. Im converting everything to Base64 string.
Client:
Public Sub SendMessage(ByVal msg As String) Try SyncLock myclient.GetStream sw = New IO.StreamWriter(myclient.GetStream)

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.
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.
Im 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?
I have 15 checkboxes in my vb.net form during runtime some of the checkboxes in control array are set backcolor by the colordialog using the following code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim a As Integer For a = 1 To 15
[code]....
My question is i want to send the colors filled in the check boxes into the sql server table throug insertsql statement my trial code is as follows but it is wrong
how to creat a client and a server and pass text between them (like a messenger), and it works just fine
so my question is : how do I send a command to the server, for example, open a program (like notpad) or do tasks or search the remote pc or even shutt it down??
note that am not trying to make a trojan or anything like that, I have two pcs and I was just wondering how to do it ?
I have 15 checkboxes in my vb.net form they have been set by following code

My question is i want to send the colors filled in the check boxes into the sql server table throug insertsql statement. at the same time the name in the textbox24 is also added to the sql table. The table has 2 fields models and colors if one model is inserted into the table cell and 5 colors are selected in the check boxes the table is fill with the name of the model is same and colors are different my trial code is as follows but it is wrong and only one row is inserted into the table

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'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 want to send image from server to client via .net Sockets and assign it to a picturebox. but I got problem in receiving data, it's 'Server' side code:
Although im using this simple logic the image that is being displayed on the remote machine the one that i send is not the same as you can see. In fact 90% is missing! The Image Size is 256KB JPG
I am testing an server-client application which captures a desktop's screenshot, saves it on a directory and then sends it to the server. But i am facing a problem. It sends me 0 bytes :S. Here is the client's
Dim i As Integer Dim ReadData(2047) As Byte Dim ReadLength As Long
It's for telephony applications. But in this system is an block called smtpSend.Now i can fill in the smtp server but there is no field to fill in the username and pasword.Is there another way to login the server to send email? Perhaps something like: [URL]
