Significantly, because browsers need to have the ports used by HTTP open, most corporate firewalls have the ports open required for regular HTTP as well as secured HTTP using the Secure Sockets Layer (SSL) protocol (HTTPS) Putting XML and HTTP together seems like a natural A new protocol based on XML and HTTP named the Simple Object Access Protocol (SOAP) was first proposed to the World Wide Web Consortium (W3C) in 1999 SOAP uses XML over HTTP to conveniently send a request and get back a response Because XML and HTTP are standards, the applications that supply or consume XML Web services can be created in any language and can run on whatever platform is most convenient In addition to XML and HTTP, several other protocols can be used in conjunction with SOAP: Web Services Description Language (WSDL); Universal Description, Discovery, and Integration (UDDI); and Discovery. .net qr code reader .

The QR code generation routines are fully ... need to generate sequence values that will be used as keys that cannot conflict across tables. Another limitation is that an identity value is generated when an INSERT statement is issued, not before. There might be cases where you need to generate the new sequence value and then use it in an INSERT statement, and not the other way around. Another aspect of the IDENTITY property that can be considered a limitation in some cases is that identity values are assigned in an asynchronous manner. This means that multiple sessions issuing multirow inserts might end up getting nonsequential identity values. Moreover, the assignment of a new identity value is not part of the transaction in which the INSERT was issued. These facts have several implications. SQL Server will increment the table's identity value regardless of whether the insert succeeds or fails. You might end up with gaps in the sequence that were not generated by deletions. Some systems cannot allow missing values that cannot be accounted for (for example, invoicing systems). Try telling the Internal Revenue Service (IRS) that some of the missing invoice IDs in your system are a result of the asynchronous manner in which identity values are managed. net qr code reader open source QR Code Scanner & Reader Control SDK for VB .

A library which supports decoding and generating of barcodes (like QR Code , PDF 417, EAN, UPC, Aztec, Data Matrix, Codabar) within images. The project is a port of the java based barcode reader and generator library ZXing . It has been ported by hand with a lot of optimizations and improvements. I'll suggest a couple of solutions to the problem of maintaining a custom sequencing mechanism. I'll show both synchronous and asynchronous solutions. WSDL was developed by Microsoft, IBM, and others WSDL is an XML schema that describes the methods and parameters of a Web service An XML schema is grammar that describes a set of tags to be used within an XML document Given an XML schema, it s possible to determine exactly what data is contained in a conforming XML document and of course, you can also validate an XML document UDDI is a platform-independent, open framework for describing services, discovering businesses, and integrating services on the Web UDDI was proposed by IBM and Microsoft You can learn more about UDDI at http://wwwuddiorg Discovery is a Microsoft-sponsored proprietary protocol for XML Web services discovery Discovery uses a disco file to locate and interrogate XML Web services A . free qr code reader for .net VB .

NET OCR Library API for Text Recognition from Images in C# & VB . You need a synchronous sequence generator when you must account for all values in the sequence. The classic scenario for such a sequence is generating invoice numbers. The way to guarantee that no gaps occur is to lock the sequence resource when you need to increment it and release the lock only when the transaction is finished. If you think about it, that's exactly how exclusive locks behave when you modify data in a transactionthat is, a lock is acquired to modify data, and it's released when the transaction is finished (committed or rolled back). To maintain such a sequence, create a table with a single row and a single column holding the last sequence value used. Initially, populate it with a zero if you want the first value in the sequence to be 1: USE tempdb; GO IF OBJECT_ID('dbo.SyncSeq') IS NOT NULL DROP TABLE dbo.SyncSeq; GO CREATE TABLE dbo.SyncSeq(val INT); INSERT INTO dbo.SyncSeq VALUES(0); and revenue, and reduce the risk of making a loss The more customers you have, the easier it becomes to predict aggregate usage patterns for a service From the customer s perspective, charging a fixed fee for the service means that the customer knows in advance exactly what their costs will be for the next billing period This also means that you have a much simpler billing system Some costs, like those associated with storage and transactions, will be variable and depend on the number of customers you have and how they use the service Other costs, such as compute costs or the cost of a SQL Azure instance, will effectively be fixed To be profitable, you need to sell sufficient subscriptions to cover both the fixed and variable costs. disco file is a simple XML document that contains links to other resources that describe the XML Web service, as shown here: < xml version="10" encoding="utf-8" > <discovery xmlns:xsi="http://wwww3org/2001/XMLSchema-instance" xmlns:xsd="http://wwww3org/2001/XMLSchema" xmlns="http://schemasxmlsoaporg/disco/"> <contractRef ref="http://localhost/10_SimpleService/Simpleasmx wsdl" docRef="http://localhost/10_SimpleService/Simpleasmx" xmlns="http://schemasxmlsoaporg/disco/scl/" />. Now that the sequence table is in place, I'll describe how you get a single sequence value or a block of sequence values at once. qr code reader c# .net ZXing . Net - CodePlex Archive
