Passing value of an array to WCF Test Client

2013-10-02T06:35:00.005-07:00

This blog might look very simple but at least useful for first time users of WCF test client .
The Question here is how to pass the value of an array to WCF Test Client
Your Service Method method looks like the below ; you may notice that the method accepts a List<String> Values as input parameter .

Now Lets Run the WCF Project and see how it look like in the Test Client

Your Test Lists the method and its Parameters as shown in the above screen shot

Now Lets see how we can Pass the Values to the array . In Normal scenario you may not notice how we can enter the values . But you may notice one thing that the length of the array is Zero (0) .
Now change the length of the array to 2 and see what is the change happening

Now you can see the array value section is modified with an expander an you are provided with two options to enter the values

Enter the values in the Value field and test your service .

Happy Coding :)

MVC–Mobile View Rendering Issue–A Bug in MVC 4

2013-04-02T02:47:00.001-07:00

Last month , we had a tough situation with one of our client projects which is developed in MVC 4 and it has got Mobile views equivalent to all the views . Everything was fine until we deploys the final production version . After deployment the application behaved normally and the smoke testing was also went fine . But things went south when the next day the client reported a major issue with the IPhone/I Pad UI, as the desktop UI is getting rendered in IPhone . Lets think how weird it can be . The team started the analysis and we absolutely don’t have any clue what could have happened . We analyzed the code deeply and can not find anything funky in it . That said we were absolutely stuck at that point .

I had a quick meeting with the team after the discussion with the client and who was already upset on the issue . We decided to lets give our final hope to Google and start digging in Google . Finally we found that there reported a known issue with MVC 4 regarding to Display mode provider

So finally we got some hope and we followed the steps mentioned in the blog post mentioned in Microsoft web site .

http://blogs.msdn.com/b/rickandy/archive/2012/09/17/asp-net-mvc-4-mobile-caching-bug-fixed.aspx

There is a patch from Microsoft as Nuget Package which resolves this issue . To install the Nuget package please follow the steps below

Now how do we test this . Also please note that this issue can’t appear in debug mode . For testing we have a sample windows application , where it launches with two browser windows embedded . We have created two instances of our application one with the patch and the other one without it , published in release modes and hosted in IIS . The embedded browser in the windows app first refresh after 20 minutes and after that every one minute . This way we were able to prove the fix was working .

Please feel free to post your comments and questions .

Jquery Live Search – A Sample Implementation of John Nunemaker’s Jquery Live Search

2011-12-07T05:06:00.001-08:00

This week actually I was looking for a Jquery Live search Plugin . While browsing through , I found a very beautiful implementation by John Nunemaker (The Original article you can found here ) .

Later I noticed that many people are looking for a code which helps them to implement this very easily .

Please see the implementation below

First of all you have to download and add the live search plugin from here and Quick Silver Plugin from here to your project.

And see the implementation Below

There was no endpoint listening at http://mysite/TestService.svc that could accept the message. When Trying to do large data transfer

2011-11-04T09:44:00.001-07:00

This issue regularly happens when we try to upload when there is no end point listens( or could not connect to the server ) at the provided address .

But in some scenarios this happens when we tries to upload or download large data through the service . We had this issue some time back and did a lot of research .

Finally we found the issue and by have some configuration changes we resolved the issue .

The configuration changes that we did to resolve this issue are given below

STEP 1 : Increased maxrequestlength property in httpruntime config entry under <System.Web>

<system.web>
<httpRuntime executionTimeout="4800" maxRequestLength="500000000"/>

</system.web>

STEP 2 :   Increased maxAllowedContentLength value

<system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="500000000"></requestLimits>
      </requestFiltering>
    </security>
</system.webServer>

STEP 3: Increased ReaderQuotas

<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" maxArrayLength="2147483647" />

By doing these three changes , we could be able to have large data transfers without any issues.

Crystal Reports Runtime Error–Crystal Reports for VS 2010 Issue

2011-10-24T03:57:00.001-07:00

Error :

An error has occurred while attempting to load the Crystal Reports runtime. Either the Crystal Reports registry key permissions are insufficient, or the Crystal Reports runtime is not installed correctly. Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required. Please go to http://www.businessobjects.com/support for more information.

Solution :

Check your crystal reports version , if you are not using CR 13 then download and install 13 from the below location first . http://downloads.businessobjects.com/akdlm/cr4vs2010/CRforVS_13_0.exe .

Then ensure that you have the following folders created under your website root ( the root website where your application is hosted; )

Under Root -> aspnet_client -> system_web -> 4_0_30319 ->crystalreportviewer13 -> ........ etc..

by default when you install crystal report thease folder would be craeted under default website . if you have a seperate website created then please copy these folders ther

2011-10-12T08:15:00.001-07:00

Last week we had this issue when working with an Outlook Addin. After a lot of trial and errors , finally we got this solution .

Run Command Prompt as Administrator and execute the below command

netsh http add urlacl http://+:8000/ user=domain\username.

Happy Coding
