Create Multiple Sockets As An Index?

May 10, 2011

I have a VB application where winsock is used. I want to convert it to VB.Net, so as I understand I should use System.net.sockets to do this.

But the problem is in the VB application multiple sockets are created by using the index feature of the winsock . example

Load Socket(isocket)

where isocket is an integer variable that is incremented each time, for a new connection request.

So how do I do the same, ie. open multiple sockets in vb.net?

Selecting Items At Same Index In Multiple Lists?

Apr 6, 2012

I am working on a project for software engineering where we are trying to create a warehouse inventory system. I have created an inventory page where I can add/delete/search for an item as well as access invoices and reorder items... i am struggling on the delete item part. I have my design set up where there are four different lists on my page. One for name, one for serial number, one for RFID number and one for amount in stock. I want to be able to select an item by name and its information in serial number, rfid, and amount also select and have no idea how to go about this..I wanted to use four different lists because I need to be able to delete an item from the list and it remove just one from that stock and not the entire item unless there is only one of that item left in stock.

for my inventory page

Public Class InventoryDepartment
Private Sub InventoryDepartment_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Create An Index On Table

Sep 2, 2009

I want to create an index on my table. I used the following command Code:

cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:database.mdb;Persist Security Info=False")
cn.Open()
cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT (ITEM_NO)", cn)
cmd.ExecuteNonQuery()

Now I want to use this. Is there a file created with some extension when i do an Indexing?. Is the above statment actually index the field, ITEM_NO or do i have to use ALTER TABLE command? Currently I am getting error "Cannot execute data definition statements on linked data sources"

Create An Application That Calculates Body Mass Index?

Nov 10, 2009

I am working in Visual Basic 2008 and am trying to create an application that calculates body mass index. I have the entire form complete as well as much of the source code, but I am having trouble creating the code for input validation. On the form I have a text box for entering weight and a text box for entering height, which are both used to calculate the body mass index. Therefore, both text boxes input information cannot be negative or an illegal character ( $, @, !...) The input validation is supposed to present a Message Box that displays something along the lines of "Please enter numeric values" when input values are illegal characters "Please enter a positive number" when input values are negative "Invalid Entry" when input values equal 0

Here is my code:

Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click

.net - Given A Large Number Of Objects, Create Multiple Forms In Designer For Them Or Use Code To Create The Forms?

Dec 29, 2010

If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.

#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

Comparing Array Index To Combo Box Index?

Nov 14, 2010

I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .
