The Customer form will enable users to register themselves as customers. Table 12-3 shows the IDs of the controls (that are used in code examples) on the Customer form.

As discussed in 414, worker thread designs can sometimes improve performance compared to thread-per-task designs They can also be used to schedule and optimize execution of service requests made by different clients As a famous example, consider a class controlling read and write access for a disk containing many cylinders but only one read/write head The interface for the service contains just read and write methods In practice, it would surely use file block indicators instead of raw cylinder numbers and would deal with or throw various IO exceptions, here abbreviated as a single Failure exception interface Disk { void read(int cylinderNumber, byte[] buffer) throws Failure; void write(int cylinderNumber, byte[] buffer) throws Failure; } vb.net barcode scanner programming How to read input from a barcode scanner in vb.net without using a ...

I've used that one: http://www.codeproject.com/Articles/12803/Read-Barcodes-from-an-Image a few years ago... maybe it's helpful for your ... The sample forms use a DataGrid control to display records from the tables stored in a SQL database on a SQL server. A DataGrid control enables a form to display data bound to a data source. Accessing data After designing the forms, you'll add the desired functionality to them. First, you'll add the functionality to the Order form. The form should enable customers to view the complete product list by clicking the View Product List button. Also, the form should enable customers to view the details of a specific product by clicking the View Product Details button. To implement this functionality, open the code behind file (with .vb extension) of the Order form. At the top of the Order form, import the two namespaces as follows: Imports System.Data Imports System.Data.SqlClient Next, in the Click event of the button labeled View Product List, enter the following code: 'Declare the objects of the SqlConnection, 'SqlDataAdapter, and DataSet classes Dim DS As DataSet Dim MyConnection As SqlConnection Dim MyCommand As SqlDataAdapter Rather than servicing access requests in the order they are made, it is faster on average to sweep the head across the cylinders, accessing cylinders in ascending order and then resetting the head position back to the beginning after each sweep (Depending in part on the type of disk, it may be even better to arrange requests in both ascending and descending sweeps, but we will stick to this version) This policy would be tricky to implement without some kind of auxiliary data structure The enabling condition for a request to execute is: Wait until the current request cylinder number is the least greater cylinder number relative to that of the current disk head of all of those currently waiting, or is the least numbered cylinder if the head cylinder number is greater than that of all requests This condition is too awkward, inefficient, and possibly even deadlock-prone to try to coordinate across a set of otherwise independent clients But it can be implemented fairly easily with the help of an ordered queue employed by a single worker thread Tasks can be added to the queue in cylinderbased order, then executed when their turns arrive This "elevator algorithm" is easiest to arrange by using a two-part queue, one for the current sweep and one for the next sweep The resulting framework combines Future-like constructs with the worker thread designs from 414 To set this up, we can define a Runnable class to include the extra bookkeeping associated with DiskTasks The queue class uses the semaphore-based approach discussed in 341, but here applied to ordered linked lists The server class constructs a worker thread that runs tasks from the queue The public service methods create tasks, place them on the queue, and then wait them out before returning to clients 'Initializing the SqlConnection object MyConnection = New SqlConnection ("server=localhost; uid=sa;pwd=;database=Sales") 'Initializing the SqlDataAdapter object with the SQL 'query to access data from the Products table MyCommand = New SqlDataAdapter("select * from Products", MyConnection) 'Initializing the DataSet object and filling the data set with the query result DS = new DataSet() MyCommand.Fill(DS,"Products") 'Setting the DataSource property of the DataGrid control MyDataGrid.DataSource=DS.Tables("Products").DefaultView 'Binding the DataGrid control with the data MyDataGrid.DataBind() In this code, the comments provide explanation for the statements that follow. However, some statements need more explanation: When initializing the SqlConnection object, the constructor takes four parameters: o The first parameter, which represents the SQL Server, is localhost, indicating that the server resides on the local computer. However, if the SQL server resides on a network, you need to give its complete address. o The uid and pwd parameters represent the User ID and Password on the SQL Server. o The database parameter represents the name of the SQL database that you want to access. In this case, the database is "Sales." When initializing the SqlDataAdapter object, the constructor takes two parameters: o The first parameter represents the SQL query. In this case, the query is used to retrieve all the records from the Products table. o The second parameter represents the SqlConnection object. The Fill method of the SqlDataAdapter class is used to fill the DataSet object with the data. This method takes two parameters: The DataSet object The identifier for the DataTable Move one page (4K or 8K) vb.net barcode reader from image Reading barcode using vb.net code - CodeProject
