I suspect the error means what it says. What have you done to try to correct it ?

Embedded media player problem

I used embedded mp. in my web site. When i used an mp4 file as target with http protocol(ex. http://212.10.22.22/xx.mp4), it doesnt play. but when i used it as local file(c:\xx.mp4) it plays. There is no file location mistake. Because i can download from http://212.10.22.22/xx.mp4 (this is a sample location.) Wİndows media player itself cant open it from http address(from url). But Media player classic or vlc player can. And lastly not all files behave like this. I can play some files in embedded media player with both http and local conditions. Code snippet:
OBJECT ID="Player" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6"
WIDTH="440"
HEIGHT="380"
PARAM NAME="AutoStart" VALUE="True"
PARAM NAME="URL" VALUE="http://212.10.22.22/xxx.mp4" ...
Please help.this is vey serious

You can simply do it usign AJAX. Try to use AJAX UpdatePanel and UpdateProgressBar.

Let us know if you need further help.

there are two ways to achieve this..

if you are using ajax then you need to put gif like
http://www.cis.uab.edu/forensics/blog/loading.gif[^]

in your update progress control which is related to ajax update panel.

or second thing if you want to handle it manually then you can show and hide it on start and end of each event manually.

I assume you want to trigger that event during page_load.
Why don't you put the code in the event handler in some other method (a new one, which you must implement). Then you call the new method both in the event handler and in handler for page_load?

use this..

Create this in page load and call the SelectedIndexChanged

object sender1 = new object();
EventArgs e1 =new EventArgs();
DropDownList1_SelectedIndexChanged(sender1, e1);

event:
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{

}

Web Service - HttpContext.Current is null

I created a web service with a method in it that returns the client's IP address. If I "view in browser" on the web service, the method works. If I call that method from a desktop application, The method throws an exception because HttpContext.Current is null.

How should I go about retrieving the client's IP address?

Here's the line I'm trying to use:

string clientIP = HttpContext.Current.Request.UserHostAddress;

It worked for me. HttpContext was not null when I tried. You can also try this.Context.Request.UserHostAddress as well.

This doesn't work either. Remember - I'm making the call from a desktop application - not a ASP.net web page.

That's not going to make a property in HttpContext null is it? In fact, if there was a missing using, it wouldn't even compile.

I understand that you are calling from a Desktop application and it worked just fine for me. Can you provide additional informations to reproduce this? I believe you are using a SOAP web service. Here is what I did and which worked for me.

In Web service:

[WebMethod]
public string TestHttpContext()
{
    if (HttpContext.Current != null)
        return "Context is not null";
    else
        return "Context is null!";
}

In Desktop application:

ServiceReference1.Service1SoapClient s = new ServiceReference1.Service1SoapClient();
string str = s.TestHttpContext();
Console.WriteLine(str); // Prints Context is not null

I also tried moving the HttpContext check to other class library as part of reproducing. But everything worked as expected.

If you can provide more information, I will try to reproduce.

Hi John

These two can give you the ip of a Client

string clientIP = Request.ServerVariables ["REMOTE_ADDR"];

string clientIP = Request.UserHostAddress;

Kind Regards

I believe you are blurring the lines between an Internet application and a desktop application.

When the application is running on the Internet you are executing on a hosting server which has a published IP address. Thus resolving it using HttpContext.Current.Request.UserHostAddress;

The IP address of a client machine executing a desktop application will be 127.0.0.1, the loop back IP address.

He is either working with a web service or a desktop application. Never both.

Thus my comment about blurring the lines between Internet applications (web services) and desktop applications.

Please confine you snipping to my post and not try to make it a global war.

Better yet if you would like to continue to snipe take it to the soapbox.

Jimmy,
As per my understanding he is consuming a Web Service from a desktop Application. Current Context returning null because of that. Smile | :)

Right I was mistaken there.

When he calls from a browser there is a current context but not from a desktop application.
