The name of this attribute is hiddenXXX, where XXX represents the name of the column in this case, hiddenemployeeid. The new attribute belongs to the msdata namespace. Note In the context of the DiffGram, the msdata:hiddenXXX attribute is a full replacement for the hidden column in other words, the information is not hidden at all, but the name of the column is a bit camouflaged. itextsharp read pdf fields vb.net: Read text from PDF using iTextSharp vb.net read pdf file text Read a PDF Line by Line - iTextSharp - Stack Overflow

Hello,. As Ashish Pandey pointed out that libraries such as iTextSharp are the best way to read PDF documents (see licensing) . You could ... After getting the class name of the exception, I just had to walk the stack. I'd already gotten the ICorDebugChainEnum interface, so walking the stack was a simple matter of following the algorithm discussed in the DebugRef.DOC file. The only interesting issue regarding the stack walking is that you can't walk native stacks with the debugging API. To check whether a chain is a native, call ICorDebugChain::IsManaged. I've found ExceptionMon to be invaluable to help me keep an eye on the exceptions my applications are generating. I'm perfectly happy with the text file output, but you might want to consider adding an option to push the output over to a GUI application so that you can see the exceptions in almost real time. Adding that option isn't a huge programming exercise and would be an excellent way to learn about Windows Forms programming! Exception Usage in .NET Now that ExceptionMon is keeping an eye on your exceptions, I want to discuss using exceptions in .NET. The fact that .NET has exceptions built right in is certainly a cause for rejoicing. For those of us who came from C++ Win32 land, C++ exceptions were a great 423 vb.net pdf read text How to Extract Text from PDF Document in C#, VB . NET - E-Iceblue

DiffGram Format Annotations Another remarkable difference between the ADO.NET XML normal form and the DiffGram's data instance is that the latter includes extra attributes such as id, hasChanges, hasErrors, and rowOrder. The extra attributes come from a couple of custom namespaces that are referenced at the beginning of the DiffGram. These special attributes are used to flag nodes, thus relating elements across the various sections data instance, changes, and errors. Table 10-1 lists all the DiffGram special attributes, also commonly referred to as annotations. Table 10-1: DiffGram Annotations Attribute Description diffgr:error Contains the text that describes the error for the row or a column on the row. diffgr:hasChanges Indicates that the row has been modified or inserted. diffgr:hasErrors diffgr:id diffgr:parentId msdata:hiddenXXX msdata:rowOrder Indicates that the row contains an error. Returns the unique ID used to couple rows across sections. Returns the unique ID for the parent row. Replacement attribute for columns marked as hidden. XXX denotes the actual name of the column. Tracks the ordinal position of the row in the DataSet object. idea, but the implementation left a huge amount to be desired Because NET has a clean and consistent manner for handling exceptions from the NET Framework class library (FCL) out, development will get quite a bit easier in NET-land I was all set to write a complete chapter on exception handling, but my coworker Jeffrey Richter already did an outstanding job in his books Applied Microsoft NET Framework Programming (Microsoft Press, 2002) and Applied Microsoft NET Framework Programming in Microsoft Visual Basic NET (Microsoft Press, 2003) His chapters on exception handling ( 18, in both books) are mandatory reading for anyone doing NET development However, I do want to emphasize a few points on using and developing your own exceptions for your products The first key point is that exceptions are for exceptional events We've all heard that phrase, but I've found that many developers have trouble actually defining it. bull is a letter of patent or charter issued by a pope. The papal bull inter gravissimas instituted the Gregorian calendar to alleviate problems with the old Julian calendar. See http://en.wikipedia.org/wiki/Inter_gravissimas for more information. My definition is that only when you encounter an error or unexpected condition do you throw the exception One mistake I've seen developers make is using exceptions instead of a switch case statement (I really have!) The only time you throw is when something is wrong Don't return general status codes by using exceptions One argument for always using exceptions is that developers never check return values To me, that's a complete red herring argument, because if developers aren't checking return values, they aren't doing their jobs and should be fired The reason I'm mentioning this is that I've seen people overusing exceptions when the code would be much cleaner and faster if they would simply return a value The general rule I apply to my code is that I will always throw exceptions out of public methods and properties on error conditions. There's no special reason for annotations to come from different namespaces it's just a more rational categorization. Attributes in the diffgr namespace relate elements from 365 That way there's a consistent means of error handling for anyone using my code Internally to my class, I will use return values instead of throwing on internal helper functions so that I can keep my exception throwing in the main methods Of course, if one of those internal-only methods encounters a true error condition, I'll do the throw right there It's all a matter of common sense I've mentioned the performance hit because even though exceptions seem to be free in NET, they are implemented internally with standard structured exception handling (SEH) If you want to verify this, simply debug a NET application using native mode only debugging you'll see all those first-chance exceptions being reported when you cause an exception That means a happy trip to kernel mode on each exception The idea, again, is to throw an exception on errors, not as part of normal program flow. Boundary value analysis (BVA) is perhaps the best-known functional test technique Unfortunately, it is also typically misused because many testers assume it to be relatively easy or trivial Historical evidence demonstrates that a surprising number of problems occur at boundaries of linear variables, so we must carefully analyze the boundary conditions of linear variable data to avoid overlooking boundary class defects When BVA is used in conjunction with equivalence class partitioning, the BVA functional technique can be very effective in systematically analyzing the boundary values of linear variables for independent input and output parameters. different blocks Attributes in the msdata namespace represent working information that is useful to know when you're processing the DiffGram Cross-Section Links Each row rendered in a DiffGram is given a unique ID The ID is automatically generated and consists of the table name followed by a one-based index for example, Employees1, Employees2, and so on The diffgr:id attribute is used as a key to retrieve the original data and the errors of a row from the <diffgr:before> and <diffgr:errors> sections The following DiffGram contains a modified row: <diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"> <NorthwindInfo> <Employees diffgr:id="Employees1" msdata:rowOrder="0" diffgr:hasChanges="modified" employeeid="1" lastname="Davolio" firstname="Michela" /> .. </NorthwindInfo> <diffgr:before> <Employees diffgr:id="Employees1" msdata:rowOrder="0" employeeid="1" lastname="Davolio" firstname="Nancy" /> .</diffgr:before> </diffgr:diffgram> The same row can be referenced in any, or even all, of the DiffGram blocks If the row is currently part of the DataSet object, you will find it in the data instance block. The biggest problem with using exceptions is that it's difficult to know what you should be catching when using the FCL As Jeffrey points out in his chapter on exceptions (a rule you've probably had beaten into your head), catch only the exceptions germane to the objects you are using Each method and property in the FCL documentation has a section named Exceptions I always double-check the help when using each property or method (fortunately the F1 help has gotten smart enough to jump to the correct item) and check any exceptions thrown so that I can ensure I'm catching only what the documentation says is thrown Keep your exception catching focused so that you don't accidentally chomp those you didn't expect. Microsoft uses the same documentation comments in C# that you use to generate the MSDN help documentation, and as I pointed out in 9, you can generate nearly identical documentation with the excellent NDoc tool available from http://ndocsourceforgenet To make life easier for anyone using your objects, you have to fill out the <exception></exception> tag and indicate any exceptions you throw in your code It's also an excellent idea to double-check all FCL calls you make and to indicate which exceptions can be thrown from those methods so that you are giving the full report 424. BVA or boundary testing is especially useful for detecting the following types of errors: Incorrect artificial constraints of a data type Erroneously assigned relational operators Wrapping of data types Problems with looping structures Off-by-one errors What is a Boundary Value in Software In the context of a software program, a boundary value is a specific value at the extreme edges of an independent linear variable or at the edge or edges of equivalence class subsets of an independent linear variable Similar to how borders mark a country's physical territory, boundary values are specific data points at the extreme ranges of a linear variable For example, in the Next Date program the minimum input date is 1/1/1582 and the maximum input year is 12/31/3000 These values represent the extreme minimum and maximum boundaries, respectively, for the combined month, day, and year variables. vb.net itextsharp pdfreader How to Convert PDF to Text in .
