How to Extract Text from PDF Document in C# , VB.NET Currently, if you use the [EqualToProperty] custom validation rule (which we created earlier in the chapter) in a form with client-side validation enabled, rules from Data Annotations may be validated on the client, but [EqualToProperty] will not it will only be validated on the server. It s hardly surprising ASP.NET MVC can t automatically translate arbitrary server-side .NET code into JavaScript. Let s see how to use ModelValidator s GetClientValidationRules(), plus some JavaScript code, to run [EqualToProperty] on the client too. First, update EqualToPropertyValidator by overriding its GetClientValidationRules() method. You can return any ValidationType and ValidationParameters values these will be made available on the client as part of the rule s JSON description. public class EqualToPropertyValidator : ModelValidator { // ... rest as before public override IEnumerable<ModelClientValidationRule> GetClientValidationRules() { var clientValidationRule = new ModelClientValidationRule { ValidationType = "EqualToProperty", ErrorMessage = "This value must equal the value of " + compareProperty }; clientValidationRule.ValidationParameters["compareTo"] = compareProperty; yield return clientValidationRule; } } Next, add some JavaScript code directly after wherever you ve referenced MicrosoftMvcValidation.js, adding a new custom validator to the client-side validation registry. Note that your new client-side validator must be named to match whatever ValidationType you declare in your ModelClientValidationRule, which in this case is EqualToProperty. <script type="text/javascript"> Sys.Mvc.ValidatorRegistry.validators.EqualToProperty = function (rule) { // Prepare by extracting any parameters sent from the server var compareProperty = rule.ValidationParameters.compareTo; // Return a function that tests a value for validity c# extract text from pdf using pdfsharp: Extract Text from PDF in C# (100% .NET) - CodeProject c# read pdf text itextsharp iTextsharp read table data | The ASP.NET Forums

Aug 16, 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 <exec> task used in Listing 7-10 takes a little bit of explaining. First, the way Ant passes arguments to PGP means that the space before the filename in, for example, -o ${build}/ ${file}.asc will cause PGP to try to make a file called ' build/antBook-docs.zip.asc', including the spaces, which can t be done. To get around this, you have split the argument in two and send it to PGP one after the other. This means that order is important here. An alternative would be to do the following and eliminate the space: <arg value="-o${build}/${file}.asc"/> The +force and +batchmode command-line options are designed for situations where automatic or unattended processes try to generate hashes, which is exactly what you are doing here. The first one suppresses confirmation questions such as, Are you sure you want to overwrite this file The second removes, among other things, the prompt for a password if you forget to supply one or supply the wrong one. You d probably rather continue with the build in this case than have it hang waiting for a response. You won t get a PGP hash, but you will get MD5 and SHA1 hashes. When you run the packaging targets now, don t forget to set the -Dpgp.password option at the command line should you not want to place the pgp.password property in the build file (and you probably shouldn t). c# extract text from pdf How to read pdf file and extract contents using iTextSharp in ASP ...

Hi, I want to extract text from PDF in C# asp.net. I am using this code as following link :: Link:: ... return function (value, context) { // Find the comparison element by working out what its name must be var thisElement = context.fieldContext.elements[0]; var compareName = thisElement.name.replace(/[^\.]*$/, compareProperty); var compareElement = document.getElementsByName(compareName)[0]; // Check that their values match return value == compareElement.value; } }; </script> This is an unusually complicated client-side validator, because it has to locate another element in the HTML DOM to compare against. If you only need to validate a single value in isolation, your clientside validator would be simpler: <script type="text/javascript"> Sys.Mvc.ValidatorRegistry.validators.MyValidationType = function (rule) { return function (value, context) { // Return true if 'value' is acceptable; otherwise false. // Alternatively, return a non-null string to show a custom message } }; </script> When the framework calls your custom validation function, it passes two parameters: value, which of course is the value to be validated, and context, which has the properties listed in Table 12 10. Table 12 10. Useful Properties Available on the Context Object Passed to a Validation Function aid: 'beep_beep_action' type: 'system' callback: 'beep_beep_action' parameters: description: Beep In contrast, the record for an instance of the Beep multiple times action would look like this: aid: 2 type: 'system' callback: 'beep_beep_action' parameters: (serialized array containing the beeps parameter with its value, i.e., the number of times to beep) description: Beep three times Just before an advanced action is executed, the contents of the parameters field are unserialized and included in the $context parameter that is passed to the action. So the number of beeps in our Beep multiple times action instance will be available to beep_multiple_beep_ action() as $context['beeps']. c# parse pdf to text iText - Read PDF table content using iTextSharp
