I am trying to write an array of integers from my VB OPC client but cannot do so.
I am setting my array to the ItemValueResults, then i set the ItemValueResults to a variantwrapper. I can write individual elements from the array but not the entire array.
Maybe to be able to provide a simple example of how its done correctly. I think the issue could be in defining the OPC item as an array.

I now want to write a Windows Form app (in either C# or VB) to do the same thing. I can't make the OAuth2 process work in the GUI application. It compiles and runs, but does not work. Based on what I've seen so far, I have concluded that the GetAuthorization() function is not called.
I've tried starting the process from a button click, from the constructor, and from the form Loader method. I've tried in both C# and VB.

I failed finding a really simple Windows FTP client that any user could use, that would just prompt the user for the host + login + password, then use OpenDialog to select one or more files to upload, and just let it go. Since this tool could be used to upload files up to 10GB, it must have solid support for resume. I checked a bunch of them, and found them way too complicated.So it looks like I'll have to write my own in VB.Net but I'm no stellar programmer.Does VB.Net provide a solid FTP client component? If not, are there other (free/affordable) controls I should know about?
View 4 RepliesThis app is trying to send messages to a client listening on the port. The client's logs show that their port is being opened and closed, but no data coming in. Is there a bug or something missing in the following code, like perhaps stream.flush or stream.endwrite or a thread.sleep(0) line, that could cause this? The puzzling thing is, WireShark on the client computer does show the message my app is sending coming into the listening port.

I have a MS sql database (not server), my program reads file structure from my 2 TB external drive and saves the list a records in database. I write around 80k records every time and it takes a great time.I am currently writing records by dividing them into 2 background Worker thread 40k each. My pc is Quad core Phenom II.What is the best way to achieve this and also would there be any benefits by increasing the number of threads because mine is only a 7200rpm hdd and not raid. What I mean is HDD might be a limitation?

View 5 RepliesI'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")

We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.
