How to type half consonants in Hindi

2012-01-11T13:08:00.000-08:00

I wish I had known this since I spent about half an hour searching for a way to do it and so I want to put it down for someone else who might want the same thing. Let's say you want to type in Hindi, the word "Hindi". It is written as हिन्दी. Now I was able to do that while writing this blog because Google blogger allows for transliteration (thanks Google!) that understands that there are

HOW TO: Silverlight Treeview - Expand all nodes

2012-01-06T07:05:00.000-08:00

Here is some code that you can use to Expand All the nodes of a Treeview control in Silverlight. public class TreeViewExtensions { public static void ExpandAll(this TreeView treeView) { for (Int32 i = 0; i < treeView.Items.Count; ++i) { TreeViewItem item = treeView.ItemContainerGenerator.ContainerFromIndex(i) as TreeViewItem;

FIXED: Enterprise Library 5.0 Hands on Labs (unity - Lab 01) not working: MoneyCentral webservice down

2011-12-12T11:12:00.000-08:00

I recently tried to run the Enterprise Library 5.0 Hands-On-Labs on the Unity and found that the very first one was not working. The reason was that a Stockticker webservice that it uses has been taken down. When I tried to update it I got the following error. There was an error downloading 'http://office.microsoft.com/Research/Providers/MoneyCentral.asmx?op=DDSQuery'. The request failed with

Ok, this was again a really tricky one. Tried to find the answers but none worked.

Windows Server 2008 VHD weirdness

2011-09-02T10:28:00.001-07:00

I was trying to download a VHD for testing out Sharepoint 2010 here when I saw the following written on the page. So I thought, well since I am running a pretty powerful 64 bit machine, (but running windows 7) I could run a Windows Server 2008 on a VHD and then run Sharepoint 2010 vhd inside it. So I go to the page for downloading Windows Server 2008 Enterprise Edition (Full Install) vhd and

Silverlight Merged Dictionary Item Scope and error “Cannot find a Resource with the Name/Key Foo”

2011-04-27T11:07:00.001-07:00

As with many people who have tried to organize the resource dictionaries that are used by silverlight, I also got the error “Cannot find a Resource with the Name/Key Foo”, where Foo obviously is the name of the resource one of my styles was referencing. This is how I wanted to organize my resource dictionaries GlobalStyles.xaml Control1Styles.xaml (references items in GlobalStyles.xaml)

RadGridview / Gridview cell binding issue

2011-04-15T10:24:00.001-07:00

Well, I am trying to bind a grid to a list of X where each X contains a list of Y. Every cell in the grid houses a specific control (specified in a datatemplate) that will do something with what it’s bound to. I see that every row is getting bound properly but when I come to see what a cell in any row is bound to, it happens to be bound to the row data item X and not Y. After some time on google

Debug Silverlight Designer Errors

2011-04-08T08:54:00.001-07:00

Even though the content of this post seems pretty straightforward, but I found that this information might be useful for someone who has never done this before. Designer errors while loading a silverlight component are not that rare. And might need to find out what’s going on. Even though the designer shows you a full stack trace of the exception, it might not always be helpful. Well an easy

Alright, I have to admit, I am not that well versed in using Moq and am in the process of figuring this out myself. Also there seems to be not a lot of documentation around it. So while mocking up an object for an interface which looked like thispublic interface ICustomerServiceProxy{ void GetCustomers(Action,Exception> callback); void SaveCustomers(IEnumerable Customers,Action callback);

Very Annoying !!!! Very VERY Annoying !!! Seems like no one had the resolution to this issue when it happened to running a website using ASP .Net framework. The only options people had was to reset iis, re-register iis with .net, setting up the permissions on the ASPNET account correctly, to create a custom account and to put it manually in the machine.config, or even changing the name of your

Guidelines for Application Handover

2010-10-31T23:45:00.001-07:00

Application Handover refers to transfer of ownership of a certain type of role, required for the healthy life of an application, from one person or a team to another person or another team. A badly executed handover is all the ingredients to cause a lot of frustration and wastage of resources across the board in an organization of any size. All these un-necessary costs can be avoided if certain

IIS worker process missing! Old gotcha that keeps coming back

2010-01-27T20:17:00.001-08:00

Now this one got me scratching my head for a while. I had a virtual machine at work which was having some issues with IIS install. Hence I kept working with the built in visual studio web-server for a while. When I finally got my IIS installed I was unable to find the worker process !!! And it felt as if it should be there and maybe I am missing it somehow !!! And all this time IIS was running

Since I am mostly developing on IIS I need that to run on the default ports and hence have

There is a basic difference between how people work in India verses people in other parts of the world.
