I realized that it is difficult to serialize an XML formatted string hence instead of XML formatted string I decided to post List of Key value pair instead. This approach is working fine.

I figured it out last night. Actually this was very basic mistake that I was making. I was trying to access an array after setting it to null. I will explain it how. When result were returned that time GridHeaderModel and the IList Cells in it were defined i.e. were not null. That time ko.mapping was able to convert the model and create the model and arrary inside it. But when any ajax request were made wherein noo result was returned and GridHeaderModel was null, obviously the IList Cells was null too. That time ko.mapping did the same, the KO model that it updated, set GridHeaderModel to null too and the observable array Cells inside was no present which is as good as null. Now when I made another ajax request with some records returned, the ko.mapping tried to update the observable array Cells which did not exist (or was set to null) in KO model on the client, it failed. If instead of ajax it were fresh page load everything would have worked. So the solution is not to return any enumeration (those that will get converted to observable array) uninitialized to the client for KO model update. Hence when no record was to be returned I made sure that GridHeaderModel is not null and also made sure that the IList Cells is initialized though it did not contained any element. This fixed the problem. This problem could be explaied with following example. public class Demo { public IList DemoArray; } public class DemoUser { public void UseDemo() { var demoInstance = new Demo(); demoInstance.DemoArray.Add("First Element"); } } Here in the UseDemo() method we have initialized the class instance Demo but the IList DemoArray remains un-initialized. So when we try to access it runtime exception will be thrown. This is what was happening in my case. In first ajax response I was setting the observable array to null i.e. un-initializing it and then in next ajax response I was trying to access it.

Please accept my apology. I get frustrated sometimes, and probably should of just been more direct. On the other forum, I just ignore the questions now, and don't get involved anymore. Diagnostics: Sometimes you have to work backwards, and look at the final results in the browser output. If the results don't work, you have to pick it apart. So you start at the image tag, inspect the url. test the url in the browser bar. There's a ton of information in the browser source, it just takes some learning to read the info and understand it. If you code in CSharp, then the principals are the same. Now you work forward on the source, to make adjustments to what is sent back to the browser. The most common mistakes I see is in the use of Client Script Manager, and not registering the CS in OnInit. The 2nd mistake is not using CS WebResuorceUrl as the url in the image tag. The image url is a webresource. Sample Code in vb. This is for you to just get an idea of the stucture and use of of the client script manager, and the webresource url. Protected Overrides Sub OnInit(ByVal e As System.EventArgs) MyBase.OnInit(e) Controls.Clear() Dim cs As ClientScriptManager = Me.Page.ClientScript Dim rsType As Type = Me.GetType() Select Case \[Localization\] Case 0 rm = New ResourceManager("Admin\_PP\_Standard.labels\_en", Assembly.GetExecutingAssembly()) ci = New CultureInfo("en-US") Case 1 rm = New ResourceManager("Admin\_PP\_Standard.labels\_fr", Assembly.GetExecutingAssembly()) ci = New CultureInfo("fr-CA") Case 2 rm = New ResourceManager("Admin\_PP\_Standard.labels\_es", Assembly.GetExecutingAssembly()) ci = New CultureInfo("es-MX") End Select Dim Comment As LiteralControl Comment = New LiteralControl Comment.Text = "<!-- SignUp V1.1 for ASP.NET 4.0 -->" & vbCrLf Controls.Add(Comment) Dim img\_Name As String = Nothing Dim img\_Email As String = Nothing Dim img\_ProgressIndicator As String = Nothing Dim img\_Connect As String = Nothing Dim img\_BG\_ModalProgress As String = Nothing Select Case \[Page\_ColorTheme\] Case 0 'Light img\_Name = cs.GetWebResourceUrl(rsType, "Footer\_SignUp.ico-form\_person\_light.png") img\_

Well guys I just got the answer to the above problem. I just missed this mapping in the class SamsungPhoneMap KeyColumn("SmartPhoneBaseID"); I did not see this being mentioned anywhere, not even the Fluent Nhibernate talks about it. But all's well that ends well, I got the answer at last.

Is this happening only one one machine? Can you reproduce it on another machine. Today, I spent 30 minutes on non-issue with my boss's machine. The browser had old cached copy and clearing the cache *fixed* the issue. Yusuf Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area.

The network is already set I guess on the host. So am I supposed to use Subnet : 192.168.175.0 (Refer my first post). How do I use it. Bcz on the guest nothing is visible. Cant see any network on the guest. Or is it that I am supposed to create a new network? How do I do it? Please bear with me as I am unknown to these things modified on Friday, September 19, 2008 6:06 AM

Hey no problem man..... but thanks for the reply anyways

Hey thanks for the reply Christian, I guess there is a way out. I believe the following class can solve the problem; System.Transactions.TransactionScope Read about it at following URL http://msdn2.microsoft.com/en-us/library/system.transactions.transactionscope.aspx[^] But the problem is that I am working on .NET 1.1 while it is supported on .NET 2.0 and above. Can you suggest some way out?

Or you can include them in the page where you will use them. om pr wrote: Two, I have an HTML(not aspx) page which i want to convert to a user control. I have javascript functions being called on the "load" and "onmousedown" event for the body of the HTML page. But since user contriol do not have body so how do I implement it...? HTML you can convert to user controls. Since it doesn't have a body tag, you should call OnLoad events inside the page where you use them. All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia My Website | Ask smart questions

Hi dear, Ur code is perfect for xmlhttp, may be there is some bug in the page where u r getting response.. try debug the code by direct opening the url with passed parameters u now can easily trace the bug if any.. Hello Forum Always be in touch to help about the topic ASP.NET

exactly. I was on a mobile. So became lazy to type ! :) All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia My Website | Ask smart questions

Well i had thought about that too but our scope is limited because of some reason. We have to implement it in the business logic of the web application itself. As i had asked in the previous post...will the multithreaded concept help...?

Hey its working for me. There are some sites e.g. http://www.mediasoftpro.com/ where they give already built dll which we can easily implement in our project. All such dlls are actually wrapper to the free tool ffmpeg.exe which can convert videos and audios from one format to another. So i thought to use the tool itself instead of the wrapper dll. I have tried very simple example n its working for me so thought to share it it with all. Download ffmpeg.exe from (http://ffdshow.faireal.net/mirror/ffmpeg/). you will get a dll along with it (pthreadGC2.dll) keep both the exe and this dll together. FFmpeg Documentation (http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html) will be required for the syntax. If you run it via command prompt then this is the syntax ffmpeg -i inputfilename outputfilename If it is to be executed via .net then follow what Christianhad suggested in the post before. Process.Start can be used to execute an executable.Do remember to give write permission to the asp worker process on the folder where the resultant flv file will be saved. If you dont then the program will run without any error or warning but output file will not be produced. One more thing it do not convert .wmv files to .flv . Is there any way out to it........?
