Feature Beginning With "w" Which Allows Javascript To Access WCF/ASMX Services?

Mar 19, 2010

There is a term beginning with "w" which is an ASP.NET feature meaning javascript can access WCF/ASMX services. It is not the webmethod or webservice attributes and it is just like scripthandlerfactory.

WCF / ASMX :: Access Denied And Null Returned While Accessing Web Services From Remote Server?

Sep 2, 2010

writing a web Service and one of its web method, I want it to download a png file in form

of buffer from remote server. And My consume application will write that buffer retured by Web service in to file on User's Computer.

However, I am able to do this using Local Web Service but when I published that service on my web server, I always get null retuned

And even in one of my test code while copying file from that server , I always get Access Denied.


Following things I have done for above issue.

1] I even tried making the Anonymous user for the web service the system administrator (with the correct password), to no avail.

2] I also tried sharing out the folder I'm pulling files from to allow access from Everyone.

[Previously same service was working fine on another remote server with IIS 7.0, we checked server IIS Settings but in vain.]

if you know where we are mistaken guide me to resolve this issue as its very urgent.

Javascript - __doPostBack Rendered After Beginning Or Near End Of Form Tag

Aug 18, 2010

I'm trying to manually call the ASP.NET (3.5) javascript postback function __doPostBack from my javascript code. The problem is that the postback script block, that is normally rendered right after the beginning of the <form> tag (and the hidden fields), is occasionally rendered near the closing </form> tag. Is there any way to force it to be rendered near the beginning of the form tag? Also, how does ASP.NET decide when/where to render the postback client script block?

Edit > Additional Info: The javascript code resides inside a user control that references the __doPostBack function. The control itself does not contain any 'postback controls' that would call that function. (When I mention 'postback controls', I mean ASP.net controls that call the __doPostBack function and not the asp.net ImageButton and Button controls)

Based on what I've observed and @Brian's comment on the dependency of the postback script on the availability of 'postback controls' on the page, I've found that when the page contains controls that cause postback, the __doPostBack script block is rendered after the opening <form> tag and when there are none, it renders them near the closing </form> tag (or according to this it's not even supposed to be rendered). Now it would make sense for ASP.NET not to render the postback script if there are no controls that require it, but the apparent position of the script near the closing tag is the one that still eludes me. I haven't been able to find any documentation that suggests this behavior. All I've been able to find was this.

Add a 'postback control' and set its visibility to hidden via css (not the Visible property). eg. <asp:LinkButton ID="RequirePostBackScriptLink" runat="server" style="display:none;" /> (this is what I'm using) Add the control to the Page.RegisterRequiresPostBack and implement the IPostBackDataHandler interface.

Finally, as @Jonathan_Bates mentioned in his post, the proper thing to do is to wrap the reference to __doPostBack inside a function that is an event handler to load (or ready if you're using jquery). That way, there wouldn't be a need to depend on the actual placement of the __doPostBack script.

WCF / ASMX :: How To Distribute Web Services

Sep 21, 2010

Using ASP.NET 3.5 /C# / VS 2008.

I have written some web services that I want to make available to others by subscription. The subscribers need to use the service from a specific domain / IP address and also authenticate with a user Id and password.

What exactly should I distribute to the subscriber so they can use the services, while exposing the least about my code?How can authenticate a consumer of services without always passing an Id / password for each service?

WCF / ASMX :: Starting Integration With Web Services?

Mar 25, 2010

I'm having my first experience with Web Services with .Net. I received from a client an integration manual to consume a web service they have.

In this manual I have the following information:

Request Interface: [URL]

Using SOAP request would return a XML Document with the response.

WSDL: [URL]

Request XML:

[Code]....

There's also XSD for the response XML.

Well, I'm having a little trouble trying to figure out how to consume this web service.

I found a topic here pointing to a MSDN article. There it says that I would have to add a Web Reference for this web service, but in my case this web service is external. Do I really have to add this reference to consume the web service? If yes how do I do that?

Next I have to create the XML Document that will be sent with the SOAP request. But here's a question. Searching on the internet I found mainly two types of request XML. I don't know wich one I should use.

The first one would be:

[Code]....

The second one is a XML file with soap:Body, soap:Header, soap:Envelope, etc.

Wich one should I create with my application in order to consume the web service? If it's the second one, how would look the XML for the data of the first XML?

And finally, how do I send the Soap request? As I said above, I found a MSDN article but it assumes I'm adding a web reference to the web service on my project and I belive that in my case I won't add this reference. So, how do I consume this web service?

I'm kind of lost here and really really soon I will have to estimate how long will take to develop the web service consume code.

WCF / ASMX :: Customize Timeouts For Web Services?

Mar 25, 2010

I have a webservice, that when called, calls many other web services based on the information that was sent. I have always left the timeout as the default, or a better way to describe it, I have never changed anything.
How (and where) do I change the timeouts for each service individually. Since I have quite a few now, I want the original transaction to never take more than 30 seconds. That said. I want to go in and change the timeouts for the services I have to ping in that 30 seconds to be 5 to 10 seconds based on which one.
