Hello,

I have 3 questions.

1. How do I send the Image inside of a PictureBox to someone using my program, and to their PictureBox?

2. How can I transmit text between me and another user?

3. How can I let people enter a username and let that username stick with them throughout their current session, for when they chat, etc...?

Thank you.

You can transform pictures into bytes which you can send over a TCP Connection and then transform it back to a picture.

You can transmit text into bytes and send it over a TCP Connection and then transform it to text.

Both use the Encoding.ASCII.GetBytes & Encoding.ASCII.GetString methods.

3. Hm?

I've never dealt with TCP or used either of those Encoding.ASCII things.

3. When the two connected users chat, I want their usernames displayed.

Also, any idea how to show a list of usernames from other people trying to connect with you?

You can't use ASCII encoding to get the bytes from an image..

Im sorry I dont have time to comment the code in the example now, but I can do it later if you need help

I honestly don't understand anything you did there...

Wait, actually, here is what I am trying to replicate:

I'm trying to make one of those.

My program is sending image from a file the user selects to a picturebox on the server-side. If you didnt figure out how to use it; start the program and press 'Start listening'. It will tell you a port number.
Now, in the other form, replace the number after the colon in the textbox (90909) with the port number.
Click connect.
Press 'Send image' (idk what I called it) and select an image to send. It will show in the other form.
This method does not use

Code: Select all

Form2.PictureBox1.Image = Image.FromFile(file)

It sends the image over a TCP connection (what your webbrowser uses) to the server. This could be modified to be sent to other users of your application too, but opening ports might be needed unless you have a server that can run on its own port (on your computer, not the user's).

A while back I made an example TCP image transfer server/client, you can find this here: viewtopic.php?t=8205&p=60699#p60699

How can I transmit text between me and another user?

You could design or use a protocol that allows this feature.
