We are going to match characters, words, whitespace, and quote characters. We test for these types in methods dedicated to each token: isWordChar(), isSpaceChar(), and so on. The heart of the class is the nextToken() method. This attempts to match the next token in a given string. The Scanner stores a Context object. Parser objects use this to share results as they work through the target text. Note also a second class: ScannerState. The Scanner is designed so that Parser objects can save state, try stuff out, and restore if they ve gone down a blind alley. The getState() method populates and returns a ScannerState object. setState() uses a ScannerState object to revert state if required. c# render pdf to image: Convert PDF to Image (JPG, PNG and TIFF) in C# .

Now let s return to the two types of data-import strategies I just mentioned. You must decide on the data strategy and the user ID strategy. With the data strategy, you have two options: you can either copy the data as new data, or mirror the data instead. If you choose the Copy as New option, the data is imported as a new item. So the first time the data is imported, a new entry will be created for every archived entry. The next time the data is imported from the same file, an additional entry would be created for the same document. So you d have multiple copies of the same document when you import the file multiple times. Now suppose you mirror the data instead. The first time you import the data, a new entry is added for each imported document and a link to the original document is created. The next time you import data from a file, the newly added entry is updated and no additional entries for the same document are created. You also need to choose a user ID strategy for importing data. Because the user who originally created a document may or may not exist in the new instance of the portal, you need to choose one of these options: If a user ID does not exist in the new instance, then use your ID in place of the missing ID. Regardless of whether the user ID exists in the new system, always use your ID while importing data. pdf to excel c#: Best PDF to Excel API: Easy PDF Converter - PDF Online pdf to image convert in c# How To Convert PDF to Image Using Ghostscript API - CodeProject

Here is the Context class: class gi_parse_Context { public $resultstack = array(); function pushResult( $mixed ) { array_push( $this->resultstack, $mixed ); } function popResult( ) { return array_pop( $this->resultstack ); } function resultCount() { return count( $this->resultstack ); } function peekResult( ) { if ( empty( $this->resultstack ) ) { throw new Exception( "empty resultstack" ); } return $this->resultstack[count( $this->resultstack ) -1 ]; } } As you can see, this is just a simple stack, a convenient noticeboard for parsers to work with. It performs a similar job to that of the context class used in the Interpreter pattern, but it is not the same class. Notice that the Scanner does not itself work with a file or string. Instead it requires a Reader object. This would allow us to easily to swap in different sources of data. Here is the Reader interface and an implementation: StringReader: abstract class gi_parse_Reader { abstract function getChar(); abstract function getPos(); abstract function pushBackChar(); } class gi_parse_StringReader extends gi_parse_Reader { private $in; private $pos; function __construct( $in ) { $this->in = $in; $this->pos = 0; } After selecting the desired fields and strategies, click the Import button to import the data to your database. how to convert pdf to image using itextsharp in c# Simple and Free PDF to Image Conversion - CodeProject
