Here Mudassar Ahmed Khan has explained how to upload multiple files with ASP.Net 4.5 FileUpload control in Visual Studio 2012 and Visual Studio 2013.

With the invention of HTML5, the FileUpload control now supports selection of multiple files at once and all the selected files are uploaded together. For uploading multiple files from a FileUpload control you just need to set the AllowMultiple property to true.

The only catch is that this feature is only available in browsers supporting HTML5 i.e. Internet Explorer (IE10) or higher, Firefox and Chrome.

Here Mudassar Ahmed Khan has explained how to send or pass multiple parameters to Web Method in jQuery AJAX POST call in ASP.Net.

Generally people face issues with jQuery AJAX POST call to WebMethod when multiple parameters have to be passed, due to syntax errors the WebMethod does not get called.

Hence I have come up in an innovative way where using JSON object and JSON2 Stringify method one can easily post any number and any type of parameters to WebMethod using jQuery AJAX.

Here Mudassar Ahmed Khan has explained how to read or extract text from image using Microsoft Office Document Imaging (MODI) in ASP.Net with C# and VB.Net.

This process of reading or extracting text from images is also termed as Optical Character Recognition (OCR).

In order to illustrate the process, I am creating an example where I’ll upload an Image containing some text and then the text will be read from the Image using OCR process and finally the extracted text will be displayed in ASP.Net Label control.
