The Problem happens when Knockout tries to Bind the ViewModel to the same node multiple times. seting the viewmodel to null will not work , so to resolve this i explicidly binded the tablelement, and after that i clear the node before i bind a Viewmodel
ko.cleanNode(document.getElementById("tblsearchresults"));

Need help in writing a java soap web service with soap header.
.net client should pass the user name and password in soap header to java web service.
on authentication the function should be accessible to .net client.
How can I achieve this please help me.

Please do not post the same question in multiple forums. I have already responded this in the Java forum.
One of these days I'm going to think of a really clever signature.

i want to know how to use tracing and when to use it , i want to know why it is found in visual studio ?
|

As mentioned in MSDN, Tracing: These are statements that are intended to help track the flow of control and state of the program as it’s executing.
Imagine running a debugger, stepping along through code and checking the values of key variables in the Watch window. Tracing statements are intended to replicate that experience in cases where you can’t attach a debugger. They should ideally provide enough context that you can see which path is taken at each control point in the application and sort of follow along in the code from reading the trace statements. Tracing is enabled when the TRACE preprocessor symbol is defined at compile time, and can be in both release and debug builds. (By default, Visual Studio defines TRACE in both debug and release builds, but you can of course change this.)
About how to use it, follow these: MSDN: Configuring Tracing[^]
Actually, all you want to know about tracing: MSDN: Tracing[^]
Also go through this MSDN Support article: MSDN Support: How to trace and debug in Visual C#[^]

Think Sandeep addressed the "how to" pretty well... as to why... well, because it works very well, I've found it particularly useful when troubleshooting bugs in multi-threaded applications. Subtle bugs are sometimes almost impossible to find with other methods (such as breakpoints), so tracing gives you the ability to add debug code that will be printed and can be analyzed after the fact (similar to a log file).

Good Day All
i have a Strange issue here using the knockout lib. i have setup the Javascript like this
$(function () {
$("#lstSearchOptions").change(function () {
var data = {}
data.id = $("#lstSearchOptions option:selected").val();
$.getJSON("/Cars/SearchDetails", data, function (result) {
var model = {
SearchOptionsR: ko.observableArray(result)
}
ko.applyBindings(model, document.getElementById("tblsearchresults"));
});
$("#lstSearchOptions").blur(function () {
$("#lstSearchOptions").hide("fast");
});
});
});
and my HTML is defined like this
<table class="ResultsStyle" id="tblsearchresults" data-bind="foreach:SearchOptionsR" >
<tr>
<td rowspan="2">
</td>
<td>
Make:<div data-bind="text: Make"></div> </td>
<td colspan="2" rowspan="2">
<a href="#">View Report </a>
</td>
</tr>
<tr>
<td>
Year: <div data-bind="text: Year"/></td>
</tr>
<tr>
<td> </td>
<td>
Model</td>
<td>
<div data-bind="text: Model"></div></td>
<td> </td>
</tr>
</table>
This code it is a partial view that is hosted and called like this
@Html.Partial("_Searchplain")
and the java-script are rendered on top of the Page Layout
@Styles.Render("~/Content/searchcss")
when running my Project i get the Following error
2
Uncaught Error: Unable to parse bindings.
Message: ReferenceError: SearchOptionsR is not defined;
Bindings value: foreach:SearchOptionsR
Thanks

As far as I can tell REST is a methodology or an archecture. Is it a real tangable thing? I mean, can you look at a back-end code and determine if it is REST or not REST? How do you communicate with a WCF RESTful service? Are all WCF services RESTful?

Somewhere in your code.

Whatever way you tried to extract the file path was incorrect. As such, you no more get the full file path, just the myFileUpload.FileName.
This is based on security reasons. Further, once file is uploaded, all you need to worry/know is where is file is uploaded - path of this location. This is defined by you and can be very easily stored in DB along with the filename to access later.
Go through this article to learn on how to do it:

We maintain our own network, servers and internet connection here at work, because we find the IT services department of our owning company are too slow and bogged down with policy for our needs. Still we still neede to be able to access their network on occasion (e.g. their intranet site). You'd think that would be straightforward - they just need to set our domain as 'trusted', surely with whatever restrictions and sandbagging they deem necessary. However, they aren't willing to countenance that for who knows what reason, so I'm looking for an alternative. Preferably the solution would not involve everyone having two logins - one for our network, and one for theirs. Especially since they expire their passwords more frequently than most people here need to log in to their network.
One approach we thought of would be for our IT guy to maintain a single account on their network we could all share through our intranet (which already uses network login authentication).
Is there anyway to create a link / session that would automatically use a (different) set of network credentials when accessing a given site? Preferably such that a given user doesn't have to know the login details? (i.e., something like USERABC / PSWD1234 logs on to our intranet, then clicks on a link / app / button which uses USERQRS / PSWD7890 to login to their network)

Hi.
This issue has bothered me for some time now.
I have quite a normal website, with different html files. If I make changes to a file, I can (sometimes!) see the changes when I hit f5. But if the file is fully replaced (same name and extension though), my browser shows the previous cached page.
So I have to manually right click in the frame, and reload it to see the new version of the page.
After many times googling to address this issue, Ive come up with these meta tages in top of each page:
<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="Expires" CONTENT="-1">
<meta http-equiv='pragma' content='no-cache'>
But little does it help.
The problem is still there. Why? And how to solve it?
I´ve inspected of other sites that updates several times a day. They have have no special meta tags or alike in their html pages. And it´s of course not nescasary to update the page manually.
Is it a server side setting or what figures?
Thanks alot for your time 
|

This is not a serverside issue, cache control is arranged by the client. If the client suspects the content to be out of date the browser will sent a head request. The server then replies with status 200 if there is a new version.
To disable caching on the browser you can set the following 2 headers:
<br />
Cache-Control: no-cache, must-revalidate<br />
Expires: Sat, 26 Jul 1997 05:00:00 GMT<br />
This should disable browser cache.

Alright, so that would be like:
and
Right?

Thanks alot, I´ll give it a try

Hi again.
I´ve tried what you suggested, but I has no effect. The problem is the same 
Any idea?

I've written my first jQuery ajax function. It passes a date from the browser to a webmethod in my code-behind. From there the date is verified using a regular expression to make sure someone isn't trying to send something else back. Now, when I tested out this function before with a standard postback, it worked fine. Now, since I'm using ajax I'm getting the message back that my date is invalid, even though I can return it to the screen and it looks just fine.
My question is, how is the string formatted when it is sent from the browser to the code behind using ajax/json? Do I need to parse the date in my code behind?

You need to explain what framework you're using. In MVC, you can create a function that takes a DateTime of the same name, and the framework just magically parses it for you.
