View 3 RepliesI've created a form with a PictureBox on it and would like to dynamically create another PictureBox on the form while the program runs (to the left of the static one). I've written this code:
Dim temp As PictureBox
temp = New PictureBox

However I have hit a massive brick wall with my program. My program that I'm trying (can't emphasis this word the importance of that word) to create a Client/Server chatroom using TCPClient in Visual Basic. So far I can get my client to speak to my server. However, i'm trying to get the returned data to display in a listbox which never happened, i then tried a label, which again never happened then a text box which I'm sure you can figure out how that went! I'm not great at networking programmers nor am I not bad I'm terrible but duty calls when it comes to projects.
The code I currently have was mostly taken from the net but when I have the program fully work and I understand how the software works I intend to heavily modify for it to suit the needs of what I need to achieve. where I can get my client to display the data from the server that I have already sent to the server (which displays successfully within the server).

View 1 RepliesMy problem is fairly simple. What my code is doing to start with is opening the form by loading a bunch of things from a database. After all the questions are done (because it is a questionnaire) it is meant to save the current score and the username that was entered before, for the sake of programming I have hard-coded a username and score however I think because I am using a different command builder it keeps giving me the same error!
(I am studying A-Level so that might explain the simplicity of the code)
