Armed with the information supplied by DebugAssert, you should never again have to wonder how you got into the assertion condition! The NET Framework also supplies two other TraceListener objects To write the output to a text file, use the TextWriterTraceListener class To write the output to the event log, use the EventLogTraceListener class Unfortunately, the TextWriterTraceListener and EventLogTraceListener classes are essentially worthless because they log only the message fields to your assertions and not the stack trace at all The good news is that implementing your own TraceListener objects is fairly trivial, so as part of BugslayerUtilNETDLL, I went ahead and wrote the correct versions for TextWriterTraceListener and EventLogTraceListener for you: BugslayerTextWriterTraceListener and BugslayerEventLogTraceListener, respectively Neither BugslayerTextWriterTraceListener nor BugslayerEventLogTraceListener are very exciting classes BugslayerTextWriterTraceListener is derived directly from TextWriterTraceListener, so all it does is override the Fail method, which is what Debug. itextsharp read pdf line by line vb.net: NET PDF Text Extractor & Converter - Extract Text from PDF C#/ VB ... vb.net pdf text extract Automate PDF to Text VB . net - Stack Overflow

13 Mar 2013 ... VB . NET doesn't have a built in PDF file reader object, but a third party product called iTextSharp fills the bill nicely. Hannes du Preez ... Assert calls to do the output Keep in mind that when using BugslayerTextWriterTraceListener or TextWriterTraceListener, the associated text file for the output isn't flushed unless you set the trace element autoflush attribute to true in the application configuration file, explicitly call Close on the stream or file, or set DebugAutoFlush to true so that each write causes a flush to disk For some bizarre reason, the EventLogTraceListener class is sealed, so I couldn't derive directly from it and had to derive from the abstract TraceListener class directly However, I did retrieve the stack trace in an interesting way The default StackTrace class provided by NET makes it easy to get the current stack trace at any point, as the following snippet shows: StackTrace StkTrc = new StackTrace ( ) ; Compared with the gyrations you have to go through with native code to get a stack trace, the . itextsharp read pdf line by line vb.net C# / VB .

16 Aug 2018 ... Steps to extract text in PDF programmatically: Create a new C# console application project. Install the Syncfusion. Pdf .WinForms NuGet package as reference to your . NET Framework applications from NuGet.org. Include the following namespaces in the Program.cs file. The returned value for an attribute is always a string; the task of converting it to a more specific data type is left to the programmer GetAttribute and Item provide a way to access attributes directly but require that you know the name or the ordinal position of the attribute being accessed A third way to read attribute values is by moving the pointer to the attribute node itself and then using the Value property You enumerate the attribute nodes using the MoveToFirstAttribute and MoveToNextAttribute methods You can also change the pointer by moving directly to a given node using the MoveToAttribute method This next example demonstrates how to programmatically access any sequence of attributes for a node and concatenate their names and values in a single string. NET way is a fine example of how NET can make your life easier StackTrace returns the collection of StackFrame objects that comprise the stack Looking through the documentation for StackFrame, you'll see that it has all sorts of interesting methods for getting the source line and number The StackTrace object has a ToString method that I thought for sure would have some sort of option for adding the source and line to the resulting stack trace Alas, I was wrong Therefore, I had to spend 30 minutes coding up and testing a class that BugslayerStackTrace derived from StackTrace, which overrides ToString, to add the source and line information beside each method The two methods from BugslayerStackTrace that do the work are shown in Listing 3-3. produce the same result when used in a test That is why we don't have to test every single uppercase Unicode character between A and Z, or every possible combination of characters in the previous example ECP and the Case of the Mysterious Error Message When I was developing one of our internal training courses I stumbled upon a rather odd problem with file names on the Windows XP operating system The exercise I designed had students decompose the set of ASCII characters into equivalence class subsets for a file name passed as an argument through the common Save dialog box using Notepad on the Windows XP operating system This is no easy task because success requires a deep understanding of the hardware platform, the operating system environment, and the character set. Listing 3-3: BugslayerStackTrace building a full stack trace with source and line information /// <summary> /// Builds a readable representation of the stack trace /// </summary> /// <returns> /// A readable representation of the stack trace /// </returns> public override string ToString ( ) 76. Consider the following XML fragment: <employee id="1" lastname="Users" firstname="Joe" /> We want to create a method that, when run on this XML block of data, generates the following string: id="1" lastname="Users" firstname="Joe". { // New up the StringBuilder to hold all the stuff. StringBuilder StrBld = new StringBuilder ( ) ; // First thing on is a line feed. StrBld.Append ( DefaultLineEnd ) ; // Loop'em and do'em! You can't use foreach here as StackTrace // is not derived from IEnumerable. for ( int i = 0 ; i < FrameCount ; i++ ) { StackFrame StkFrame = GetFrame ( i ) ; if ( null != StkFrame ) { BuildFrameInfo ( StrBld , StkFrame ) ; } } return ( StrBld.ToString ( ) ) ; } /*///////////////////////////////////////////////////////////////// // Private methods. /////////////////////////////////////////////////////////////////*/ /// <summary> /// Takes care of the scut work to convert a frame into a string /// and to plop it into a string builder /// </summary> /// <param name="StrBld"> /// The StringBuilder to append the results to /// </param> /// <param name="StkFrame"> /// The stack frame to convert /// </param> private void BuildFrameInfo ( StringBuilder StrBld StackFrame { // Get the method from all the cool reflection stuff. MethodBase Meth = StkFrame.GetMethod ( ) ; // If nothing is returned, get out now. if ( null == Meth ) 77 StkFrame , ) In a past life, I built custom PC systems for clients from the motherboard up through various software configurations It was in those early days when I became all too familiar with flashing EPROMs for BIOS updates and changing jumper settings for IRQs and DMA channels to get hardware from different manufacturers to play nicely with each other I knew a few other esoteric details such as reserved memory space for LPT and COM ports 1 9 by the PC/AT BIOS This means that a base file name composed of a literal string of LPT1 or COM 6 should result in a similar error message on the Windows platform indicating that the file name is a reserved device name, or something to that effect. The method we create to do this is the user-defined function GetAttributeList GetAttributeList takes a reference to the reader and extracts attribute values for the currently selected node // Assume we call this method after having read the node string GetAttributeList(XmlReader reader) { String buf = ""; if (readerHasAttributes) while(readerMoveToNextAttribute()) buf += readerName + "=\""+ readerValue + "\" "; readerMoveToElement(); return buf; } When the pointer is not already positioned on an attribute node, calling MoveToNextAttribute is equivalent to calling MoveToFirstAttribute, which moves the pointer to the first attribute node An XML reader can move only forward, which means that no previously visited node can be revisited once you have moved on to another node This rule has a very specific exception When the pointer is positioned on an attribute node, you can move back to the parent node using the MoveToElement method. { return ; } // Grab the method. String StrMethName = Meth.ReflectedType.Name ; // Slap in the function indent if one is there. if ( null != FunctionIndent ) { StrBld.Append ( FunctionIndent ) ; } // Get the class type and name on there. StrBld.Append ( StrMethName ) ; StrBld.Append ( "." ) ; StrBld.Append ( Meth.Name ) ; StrBld.Append ( "(" ) ; // Slap the parameters on, including all param names. ParameterInfo[] Params = Meth.GetParameters ( ) ; for ( int i = 0 ; i < Params.Length ; i++ ) { ParameterInfo CurrParam = Params[ i ] ; StrBld.Append ( CurrParam.ParameterType.Name ) ; StrBld.Append ( " " ) ; StrBld.Append ( CurrParam.Name ) ; if ( i != ( Params.Length - 1 ) ) { StrBld.Append ( ", " ) ; } } // Close the param list. StrBld.Append ( ")" ) ; // Get the source and line on only if there is one. if ( null != StkFrame.GetFileName ( ) ) { // Am I supposed to indent the source put 78 If so, I need to // a line break on the end followed by the indent. if ( null != SourceIndentString ) { StrBld.Append ( LineEnd ) ; StrBld.Append ( SourceIndentString ) ; } else { // Just add a space. StrBld.Append ( ' ' ) ; } // Get the file and line of the problem on here. StrBld.Append ( StkFrame.GetFileName ( ) ) ; StrBld.Append ( "(" ) ; StrBld.Append ( StkFrame.GetFileLineNumber().ToString()); StrBld.Append ( ")" ) ; } // Always stick a line feed on. StrBld.Append ( LineEnd ) ; } This exception exists because, after all, an attribute is a particular type of node that is used to qualify the contents of the parent From this point of view, an attribute is seen as a sort of subnode, and moving between the attributes of a given node does not logically change the index of the current element node Using MoveToAttribute and MoveToFirstAttribute, you can jump from one attribute node to the next in both directions Parsing Mixed-Content Attributes Normally, the content of an attribute consists of a simple string of text If you need to use it as an instance of a more specific type (for example, a date or a Boolean value), you can convert the string using either the methods of the static classes XmlConvert (recommended) or even SystemConvert In some situations, however, the content of an attribute is mixed and includes plain text along with entities. vb.net code to extract text from pdf VB .
