My experiences with IE8

I was a bit apprehensive to use the IE8 which created a buzz amongst developers and technology enthusiasts.
But I must say I am impressed by the sheer number of features supported by IE8. First and foremostly, MS had a re-look at the pathetic rendering engine
Trident and made significant changes in Trident which are noteworthy and are visible from the outset of the browser.

My favourite features of IE8:

  • The best feature I liked was to select a part of page and use it as a live bookmark:O Yep, its as easy as it gets!
  • The addons offered from IE are cool and there are quite a few of them.
  • Great security features with respect to the private browsing sessions provided and .
  • Inter translation of pages leveraging the globalization aspect of websites.
  • As a web developer who was to constantly work with colours of web pages, width of web page elements there s great news for you. Stay on a web page and just press F12 to open the trident rendering engine. Not only the tool shows details of the page, it also provides profiling of web pages. Added to this, there are tools like colorpix and cool ruler integrated which are handy for a website designer.
  • Pretty fast browsing speed.
  • Right click options of the browser are noteworthy although most of the right click options are tightly linked to windows live and other MS products like excel and one-note.

On the down side, few features of IE8 in particular and IE in general always bother me.

  • IE8 caches a lot of data. Infact IE8`s memory consumption is comparable to that of FF owing to the caching.
  • I hate the tick tick sound when a page gets rendered. Dont know how this issue has not been noticed my MS.

So, thus ends my experiences of the short stint with IE8.Comments and discussions on the same are always welcome :)

PDF generation using .net

I had got a requirement from client to generate membership certificate as a pdf document for the person who joins the website.We researched and planned to make use a third party library called itextsharpLib.

The requirement was to generate a pdf which had a background image and some text to be placed into the pdf which was not that difficult a requirement and hence was able to finish it off within a day with help from the internet mind you.

The problem with this requirement was that there was very less documentation in the internet about the itextsharp library for .net.

Also we had planned to dynamically generate a web page and convert the HTML to pdf. But there was a lot of complexity in the requirement to generate the pdf using HTML. So, I took the easier route and generated the pdf required pretty easily.

So I refered this link to get the required tutorial needed for my requirement.

Steps I went through to get the requirement done:

  1. Instantiate the memory stream stream, required for holding the pdf document generated.
  2. Create a document object document, with the required page size and other layout options.
  3. Instantiate a PdfWriter object writer, which requires the memory stream and document as parameters.
  4. Open the document object using document.Open() method.
  5. Created the Image element and added it to the document using document.Add(img) where img is the obj of the type Image which would be implemented using the IElement interface. Prior to the adding we needed to have initialized the img properties.
  6. Created a PdfContentbyte object using the line PdfContentByte cb = writer.DirectContent;
  7. Write the content on the image between the lines cb.BeginText(); and cb.EndText(); using the method cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, "Text to be written", x-coordinate, y-coordinate,z-coordinate);
  8. Close the document object using document.close();
Now that we have the pdf document in the memory stream, putting the document in the HTTPHeader of the existing HTTPContext is pretty simple.
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentType = "application/pdf";
string test = "document";
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename="+test+".pdf");

And there you are, you will get the pdf document as an attachment in your browser.

P.S: The blog entry is under construction. Will add the code snippet and downloadable source code shortly.
