I am using the northwind database, My goal is to create an application that has a main form area for the orders and a details section (I guess a data grid view)How can I Utilize the data grid view for inputting values such as Product, Quantity, Unit Price, Extended price.... Specifically how to program the date grid view to multiply unit price by Quantity to get the extended price, then add up all the extended prices and shove that to another txtBox outside the dataGridView (txtSubtotal)Saving the header (to the Orders table) and using the InvoiceID to also save the details section in the OrdersDetail table.

"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim obj1 As New Invoice(Val(TextBox1.Text))
TextBox1.Text &= obj1.Invoice1 & vbNewLine
TextBox1.Text &= obj1.Invoice2 & vbNewLine
TextBox1.Text &= obj1.Invoice3 & vbNewLine
TextBox1.Text &= obj1.Invoice4 & vbNewLine
[CODE]...

Here at my company we have an Access application that allows users to create documents based on invoices that are in Great Plains. Documents such as invoices, packing lists, export documentation, etc., etc.This application is very old and very hard to maintain so we're doing a rewrite and I've chosen this project to be my first Visual Basic .NET project.

Dim connectionString As String = "Data Source=----------SQLEXPRESS;Initial Catalog=Flexlink;" & "Integrated Security=SSPI;"

What would be the best way to make a Windows .NET application be the only program that can be used on a computer? I have come across timers or events to switch windows back to a window with matching text and some api32 calls to make a form top most.
Is it possible to make an application like the windows lock screen where nothing can be done except that what is on screen? I want to block users from doing other things and only let administrators get to the desktop.

I'm currently using MS Visual Studio 2008 Express Edition. My .NET Framework version is 3.5. I made an application in VS 2008 and it worked perfectly. However, when I ran it at my friend's place (who's got .NET Framework 1.1), it didn't run. Now, I know that the framework incompatibility is the issue.So, what I ask is, how do I code the application so as to make it run on Framework 1.1 as well while still using VS 2008?

I made the setup project for mt VB.NET Application, but when I take it to another computer for installation, the wizard does not show any window for specifying the path. It just asks to accept the license agreement and then starts installing/copying files. Later after installation and rebooting I see the shortcut but it does not start the program/application. It just goes to a folder.

I'm making a console application with a login. The system I have now is extremely basic and very redundant. I would like the password to be masked as you type it in "*****" for example and If possible I would like to encrypt the password with md5. Can someone let me know how to/give me the code to do it.
This is my current login system:
Sub LogIn()
'A log in system to prevent unwanted users from acsessing the system
Console.Write("Username: ")
Dim username As String = Console.ReadLine.ToLower
If username = "sian" Then

I am making an application with a bar on the upper side of it. It can stretch with the form, because the anchors are on the left and right. But it fades out.

how do i make i VB .net application/tool (any sort of) like a professional one, for eg. if my tool is doing some task when i click a button which takes say 1-2 mins. , then during that phase my app should not look like it's hung (plain white window) if you know what i mean . All i'm asking is the logic for keeping my front end viewable & refreshed (possibly wit ha progressbar) while something carried out in background which takes couple of mins.

I'm trying to make a calculator application. Just as practice, as I'm new to visual basic (.NET 4.0) coding. I've got this so far.

Note, I've not programmed it to do operations yet, I'm trying to get this sorted out first. My issue is, when I enter my numbers, they do not store as a variable, they both store as zero.

Previously I used to piddle around with VB6 to develop a couple of personal projects. Following my upgrade to Windows 7, I've decided to piddle about with vb.net Express Edition 2010.If I wanted my VB6 application to blend in with the visual style of Windows, I would use the code and techniques described here. In short, I would use a Manifest file and a couple of calls within the application and most of the elements would look similar to the XP theme applied. If it was run on 2000, 95 or 98 then it would look like a standard Windows app. All was good.
Now I've moved onto vb.net, I've written a simple "Hello, world" application but I have absolutely no idea on how to make it look like the Windows 7 theme (eg. the font matches the system font and the widgets are styled correctly).Just changing the font is a hack and will look out of place on machines that are set-up differently or run a different version of Windows where the default font is different.How do I ensure my application matches the applied Windows theme irrespective of the version of Windows?

I created a simple application that when a user logons onto their Windows account, the application pops up to display the computer usage agreement.آ The user at this time has the option of accepting it or declining it. If declined they are logged out of windows, and if they accept they can continue using windows. When I installed the application logged on as the administrator, it only installed in the administrator profile, thus not allowing the application to be run from startup under any other account except admin.آ My first question is, how can I install this application that is it accessible to all user accounts? The second question is how can I program the application to freeze windows until the user clicks the accept button, without puting a timer event that if the accept button is not clicked in a certain amount of time to log off the user.

I had all types of problems before with my application size.On one computer it fits great, but on the net book the application is so big that it crashes it.For example lets say that this is my application running on a regular PC which has a 60 Cm screen This not my application. On my net book which has a 25cm screen it will look different and bigger. Can i some how have a application that is the same size. I think this is very possible to do. Kaspersky has the same feature and it works great.
