Since assertions disappear in release builds, the person who wrote the code was removing all error checking in release builds! By this point, I was livid and screamed at the top of my lungs, "Whoever wrote this needs to be fired! I can't believe we have an engineer on our staff who is this incredibly and completely @#!&*&$ stupid!" My boss got very quiet, grabbed the paper out of my hands, and quietly said, "That's my code" My career-limiting move was to start laughing hysterically as my boss walked away The Lesson I can't stress this enough: use assertions in addition to normal error handling, never as a replacement for it If you have an assertion, you need to have some sort of error handling near it in the code. vb.net print pdf to specific printer: vb.net code, print pdf file to a non-default printer. - Experts Exchange vb.net read pdf fields VB .

NET and XML classes for further use A key architectural goal for NET Framework data providers is that they must be designed to work on a rigorous per-data source basis They expose connection, transaction, command, and reader objects, all working according to the internal capabilities and structure of the DBMS As a result, the programming interface of, say, the Microsoft Access data provider will not be completely identical to that of the SQL Server provider An area in which this difference is palpable is in XML data queries OLE DB and NET Framework Managed Data Providers Prior to the advent of the NET Framework, OLE DB was considered the emerging data access technology It was well positioned to definitively replace in the heart, and the code, of developers another well-known standard for universal data access open database connectivity (ODBC). vb.net pdfreader class Displaying a PDF File in a VB .

As for my boss, when I went into his office a few weeks later to resign because I had accepted a job at a better company, I was treated to a grown person dancing on his desk and singing that it was the best day of his life.. How to Assert The first rule when using assertions is to check a single item at a time. If you check multiple conditions with just one assertion, you have no way of knowing which condition caused the failure. In the following example, I show the same function with two assertion checks. Although the assertion in the first function will catch a bad parameter, the assertion won't tell you which condition failed or even which of the three parameters is the offending one. // The wrong way to write an assertion. Which parameter was bad BOOL GetPathItem ( int i , LPTSTR szItem , int iLen ) { ASSERT ( ( i > 0 ( NULL != szItem ( ( iLen > 0 ) && ( iLen < MAX_PATH ) ) && ) && ) && OLE DB is the data access technology that translates the Universal Data Access (UDA) vision into concrete programming calls Introduced about five years ago, UDA describes a scenario in which all the data that can be expressed in a tabular format can be accessed and manipulated through a common API, no matter the actual binary format and the storage medium According to the UDA vision, special modules the OLE DB providers would be called to expose the contents of a data source to the world Another family of components the OLE DB consumers would consume such contents by interacting with the providers through a common API In designing the intermediate API for OLE DB providers and consumers to communicate through, Microsoft decided to use the key software technology of the time: the Component Object Model (COM) In this design approach, the consumer had 293. Figure 16-1: Test Excellence team room. The room can get "busy" sometimes, and we all have had to resort to headphones occasionally to cut down on the distractions, but most of the time we are all happy with the room. We have our own spaces, but we can talk face to face when we need to. Our arrangement is a bit of a compromise between a "cube farm" and an individual office. We have six in the room now, and it would probably work with a few more, but I think the team room concept would fail as team size approached double digits. The biggest benefit of the shared space is that we are all more aware than ever of the work that our teammates are doing and we have a fun, modern place to work. Perhaps the most prevalent indicator of the success of our new room was when I took over the leadership of the Test Excellence team. I chose to keep my desk in the team room. I also have an office that we all use for 1:1 (pronounced one-on-one) meetings, interviews, and other private meetings, but I enjoy spending most of my time working in what we have come to call our "test lounge." ( FALSE == IsBadStringPtr ( szItem , iLen ) ) ) ; } 65 to instantiate a COM object, query for a number of interfaces, and handle the results The provider had to implement the same number of interfaces (and even more) and access the wrapped data source at every method invocation The methods defined in the OLE DB interfaces are quite general and are not tied to the features of a particular data source Compared to OLE DB providers, NET Framework data providers implement a much smaller set of interfaces and always work within the boundaries of the NET Framework common language runtime (CLR) A NET Framework managed data provider and an OLE DB provider are different components mostly in the outermost interface, which clients use to communicate Under the hood, they look much more similar than you may expect In particular, both components use the same low-level API to talk to the physical data source For example, both the . // The proper way. Each parameter is checked individually so that you // can see which one failed. szItem , int iLen ) { ASSERT ( i > 0 ) ; ASSERT ( NULL != szItem ) ; ASSERT ( ( iLen > 0 ) && ( iLen < MAX_PATH ) ) ; ASSERT ( FALSE == IsBadStringPtr ( szItem , iLen ) ) ; } When you assert a condition, you need to strive to check the condition completely. For example, if your .NET method takes a string as a parameter and you expect the string to have something in it, checking against null checks only part of the error condition. // An example of checking only a part of the error condition bool LookupCustomerName ( string CustomerName ) { Debug.Assert ( null != CustomerName , "null != CustomerName" ) ; } You can check the full condition by also checking to see whether the string is empty. // An example of completely checking the error condition bool LookupCustomerName ( string CustomerName ) { Debug.Assert ( null != CustomerName , "null != CustomerName" ) ; Debug.Assert ( 0 CustomerName.Length" ) ; != CustomerName.Length ,"\"\" != BOOL GetPathItem ( int i , LPTSTR Perhaps the most critical role of the Test Excellence team is anticipating the future needs of testers at Microsoft and being proactive in defining the future vision of software testing. This vision is the basis for yearly planning and Test Excellence initiatives. The purpose of the vision, like most good visions, is to give direction on the discipline and to guide the work to be done. Another step I always take is to ensure that I'm asserting against specific values. The following example shows first how to check for a positive value incorrectly and then how to check for it correctly: // Example of a poorly written assertion: nCount should be positive, // but the assertion doesn't fail when nCount is negative. void UpdateListEntries ( int nCount ) { ASSERT ( nCount ) ; } 66 NET Framework data provider and the OLE DB provider access SQL Server 70 and later using Tabular Data Stream (TDS) packets Both components hook up SQL Server at the wire level, thereby providing a nearly identical performance, each from their native environment Microsoft Win32 for OLE DB and the NET Framework for managed data providers Reading from XML Queries The SQL Server NET Framework data provider makes available a particular method in its command class, SqlCommand, that explicitly lets you obtain an XML reader whenever the command text returns XML data In other words, you can choose to execute a SQL command with a trailing FOR XML clause and then pick up the results directly using an XML reader Let's see how. vb.net pdf reader Read & Parse a PDF file using VB .
