Crystal report is not displaying in Internet Explorer (Crystal Report 13 and Visual studio 2012)

I upgraded an ASP.NET application developed with VS 2008 (.NET framework 3.5 and Crystal report 10) to VS 2012 (.NET framework 4.5 and Crystal report 13). In the upgraded application, generated report was not displaying in IE. When I tested in Firefox, it displayed the report with empty first page, and when I went to the next page and came back, first page was filled with data.

Solution:

I had used an Ajax Update Panel to show the Crystal report and it was working fine before upgrade. When I removed the Update panel in the new version, it started working. But I am trying to check whether a newer Ajax version would solve the problem

Microsoft Visual Studio 2012 crashes when running crystal report 13 ( webdev.webserver40.exe stopped working )

I upgraded an ASP.NET application developed with VS 2008 (.NET framework 3.5 and Crystal report 10) to VS 2012 (.NET framework 4.5 and Crystal report 13). Upgrade was successful but most of the crystal reports gave a crashing problem that VS2012 crashed when running those reports. I tried to create a new report and when adding the SP from the new connection (ODBC connection) in report designer, VS crashed giving the same error.

Solution:

I removed the 32 bit ODBC connection  (iSeries Access ODBC Driver) and created it again and the problem was solved.

When Submit A Post To Pligg Site I Am Getting "Wrong Step" Error

Recently I noticed that my Pligg social bookmarking site does not get any new post from the community. Then I try to submit a post to the site and on the second step of the article submission page I got the error "Wrong Step". I was really confused and try to figure out the issue. When I search on the web, I found few answers and none of the solutions were addressed my issue. Some of the reasons that the support forums were discussed are:

1. "Wrong Step" error might occur due to new template you use for your pligg site.
2. Configuration changes, basically f_open() function configuration. Most of the time this could happen when your hosting company upgrade their servers or change the security configuration of their servers.

Microsoft Silverlight

Microsoft Silverlight is the new product they introduced for rich interactive web application developments. In previous topics I introduced how you can use Ajax technologies for rich web application development. We use Ajax technologies to introduce JavaScript and call server calls through JavaScript to minimize page refresh. With this method we can save lot of page refreshes but we might face some difficulties in developing Ajax enable applications when we go for complex applications. Silverlight is a powerful development platform for creating engaging, interactive user experiences for Web, desktop, and mobile applications when online or offline. With Silverlight you can build web or mobile applications very similar to desktop application developments. You know that we have much more freedom with desktop application to use complex controls. But with web application we have some limitations due to the technologies use, bandwidth, security issues...etc. The objective of Silverlight is like run desktop like application on the web or mobile browser.  But this doen't mean that Silverlight is for web or mobile application developments. You can use Silverlight for desktop applications, but here I will more concentrate on how to develop rich interactive web or mobile applications using Silverlight.

AJAX Extensions on Microsoft Visual Studio 2008

AJAX is a new trend in web development where it gives very smooth functionality for your website. In simple term we can use AJAX technology to refresh individual parts of the web page without refreshing whole page. This feature will increase the efficiency of your web page, smooth operation and enable more description web page design.

What is AJAX?
AJAX = Asynchronous JavaScript and XML.
AJAX is not a new programming language, but a new way to use existing standards.
AJAX is the art of exchanging data with a server, and update parts of a web page - without reloading the whole page.
Microsoft Visual Studio 2008 is coming with rich collection of AJAX controllers built in. AJAX is based on Java and JavaScript so it is nothing to do with .NET or Visual Studio. But most importantly we can easily use AJAX with most of the web development project. With AJAX Extensions of Visual Studio 2008 we can use AJAX with the visual studio development environment. This is really easy and fun. Let do it with a small project, so that you can easily understand the concept.
