VS 2008 - Use A Northwind Database To Display Customer And Order Information
Apr 20, 2011
I have to use a northwind database to display customer and order information. Populate a combo box with the CompanyName sorted in alphabetic order. Display the customer information in bound labels and the order information in a grid. For customers, display id,name,title,phone. For orders display the order id order date required date and shipped date. how to connect the access database file to vb.
In my sales order i use one combo that is CUSTOMER, actually it display all the data of CUSTOMER database.
at run time in SALES ORDER i saw that the CUSTOMERis not available in that combo then i want to add new customer there which save in my CUSTOMER data base WITH OUT LOSSING WHT EVER I INSERT IN SALES ORDER.
A registeration sys using a Microsoft acres database I have a table named customer info to store customer details when registering and I need coding that will add the following to my table customer I'd , firstname, lastname , phonenumber and user also has to make selection between radio buttons male or female.
I have never used Sql Server before. I have Visual Studio 2010 and whatever SQL server that comes with it but am having trouble connecting to it.DO I have to set anything up beforehand in sql server. I used the connection string to connect to the northwind database from Microsofts website but it says it can't connect
I'm trying to add 3 customers to an array that I can then display in 4 seperate text boxes on my form. First Name, Last Name, Account Number and Balance.
Public Class Customer Private firstName As String Private lastName As String Private accountNo As Integer
[code]....
Error 2 Argument not specified for parameter 'account' of 'Public Sub New(first As String, last As String, account As Integer, balance As Decimal)'.
I have an application that connected to a database (SQL Server 2000) .Is there any way to send an information and Report made by Crystal reports by mail so customers can check it from his email?
I am attempting to create a program which saves customer information for a business e.g first name, last name, address etc. but i am having trouble coding the save , new, print, next/previous record buttons.
Would someone be able to link me to a tutorial which explains how to do these?
I have a problem in that I have five text boxes pertaining to a customer/client, where there is a txtbox for each: Name; Address; City: State; Zipcode. Of course all the txtboxes are "" at initialization. I also have 2 combo boxes and a 2D array for prices which I have finally been able to understand the array logic. I have also been able to do my necessary calculations for.
My problem. The customer information is first to be validated as all being strings and not empty. The combo boxes I was able to get to tie to my 2 dimentional array and get good output and calculations for a finished product. I am just having problems with the error messages. Also I don't want summary totals unless the data is valid. In other words, the user must enter a complete address and make decisions about the two combo boxes, both of which are needed to use the price array. I will change the comboBoxes to represent dress sizes,"S" "M" "L" and "XL" and the other combobox to describe colorRedSatin or colorBlackBroadcloth with a two dollar difference in price between them. 'That would be similar enough to the problem I need to solve.
Basically I do not want any numbers to appear for price of the dress or addons to the dress unless all validation is complete. I do understand how the radio objects work for discounts and check boxes for accumulating accessories. The program should not give any totals untill the user has input all customer information and made decisions about input from combo boxes and selected calculate from menu. Right now it calculates and puts zeros in when choices are not made from the combo boxes by the user. It will include correct amounts for radio buttons and checkboxes if anything is entered. I need error messages for customer inputs and combo box inputs (if not selected from list of option in drop down for choices) (basically if nothing was put in a text box, the text box is empty. Of course the problem is the user must enter something in all 5 textboxes and not get multiple error messages in rapid succession to fix. We can't always count on our users putting in good data.. When I tried a Do While False with ORs I was getting endless looping. I could not get it to work because it will never execute because the control never passes back to the user.
I don't want to list a series of If/Thens becauser the user will see about 7 messages, where he/she only needs to be fed one at the time. I hope someone can give me some direction. I just need guidance on how to validate the text boxes and combo boxes. The code is analyzed with a "Calculate" on the menustrip. I would like for the calculation not to calculate and put outputs into the summery text boxes unless all textboxes are filled and combo boxes are valid for all the customer information and combo box choices for my two combo boxes describing what is needed for the order to calculate. There are also the radiobuttons and checkboxes, DIMs, Const, Variables, but not having problems with that part I have my indexing problems on the combo boxes worked out also, so I am not concerned about those now except for getting the error messages when I should. I hope that I have described my issues fully. I am using visual studio 8 with Windows 7
I am using a data grid view to display information from a database and I can't get it to update correctly.I can see the data from the database but when I change information and save it it changes the entire column's information. My rows need to have different values in the same column so this is a problem.Here is my code so far, what the program does is makes a list of transactions that are entered.
how to communicate from visual studio to the swf. display information/ database data. i know from flash to vb is using fscommand but how about vb to flash ? and also database information to display on flash.
I am writing a VB 2008 program to display and update records from a sql database. This particular form is used to display and modify retail store information records from the database. I am running into an issue with saving the records once they have been changed.The error message I am getting is "Update requires a valid update command when passed DataRow collection with modified rows". I am including all of my code for the form because I am not sure what is relevant. I am getting the error when SaveTheEdit() is called on line 83. [code]
I am at a stand still on this one. I know how to connect and add to the database, I just don't know how to retrieve the information so that a user can see it! If anyone could help me with code or another example.
It's a basic Access database driven e-commerce site. I have a home page, a products page, an orders page, an order confirm page, a shopping cart page and a view current orders page. The site uses an Access database with three tables. A Customer table, with all of the customer details, (FirstName, LastName, EmailAdd, CardNo, CardEx, SortCode, DeliveryAdd, Postcode)A Products table, with all the product information, (ProductID, ProductName, Price, ProductType, Images, ProductDescription). And an Orders table which contains CustomerID and ProductID.I've managed to get the orders page to work, this leads to the order confirmation page which displays the details the customer just placed.Here is what I have in the order confirmation page load event so far. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
[code]...
This returns this error "Syntax error in FROM clause." I'm guessing my SQL code is wrong. I noticed when I placed the order in the order page it added an entry in the Access database where the generated CustomerID was 12 on the customers table and 4 in the orders table. Shouldn't these numbers be the same when they are generated?

I have the following problem: I select a customer from a dropdownlist and then the gridview should load all items of all orders of that customer. I have the following query:
Dim allorders = From ord In db.Orders
Where ord.CustomerID = Convert.ToInt32(CustomerDropDownList.SelectedValue)
[CODE]..............
I also tried to modify the query as follows:
Dim orderitems = From oi In db.OrderItems
Where oi.OrderNumber = (From From ord In db.Orders
[CODE]...........
But this does not work. I just started using LINQ.
I am trying to autocomplete customer surnames direct from the Customer Datatable, using the code below which I got from another thread, but nothing is happening.
I have a program that needs to display a playlist of songs, for a band performing someplace, from a .txt file. The songs in the file are listed as follows:
All You Need is Love-Beatles Rock 4.25
[code]....
The first line is the song's title and group name. The second is the songs genre. The third line is the songs length, 4.25 is 4 minutes and 25 seconds.upon clicking a button, I need to display a playlist from this .txt file based on the number of minutes the band has to play, minutes entered into a TextBox, and the songs genre, selected from a ComboBox. The songs cannot repeat and must be random.I have already coded the program to read the .txt file but have not clue where to start with the rest.
i have made a database using vb.net 2005 and SQL Server 2005, its completed now. how do i give to the customer in a full form, I mean as a professional software?
Im trying to build an order form application that pulls information from a msaccess file.The form has 3 Textboxes labeled 1,2,3 etc//The first one is a product code, the second a description. i would like to be able to type a product code into box1 and on pressing return it populates box2 (the description).

The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.
My university has a website that students can use to check stuff like their lesson schedules, latest grades, exam times, etc. Just general information about you and your study (after you have logged in of course).For interested, this is the website (not much use without a login obviously, but still): [URL]I have been thinking lately that it would be nice to have a desktop application that could give me the same information. However, I have absolutely no idea how that would work, and whether or not it is even possible. I mean, technically it should be possible for me to get the information (how else does the website get it) provided it is not secured (even when using the correct login details). I am sure the website communicates with a database somewhere. Does that mean I could theoretically also communicate with the database (probably: read from it only, not write) for example by executing queries?If that is possible, how do I figure out which queries to use for the different pieces of information? Obviously I don't know the details of the database so I can't just send a random query and expect it to work...
Okay, I've made a local database now and everything is okay. But I don't want the normal data grid view, I want to display the information in a list view. How can I do that? Do I have to make some sql queries or something?

I am new to Visual Basic Studio 2008 Express and I also have upgraded my new Toshiba laptop with Windows 7 Home Premium. Anyway, while following a video from Microsoft about creating my first two VB programs, I discovered that I could not create a new connection to the sample Northwind database supposedly installed with Visual Basic 2008 Express. Fact is, I can't even get the program and sample db to install on my computer.
