problem with sound functionality in ASP.NET and C#

I have a problem which i am facing in my chat application. I am working on asp.net 2.0 and C#. My problem is regarding a sound functionality. I have to provide a visitor with a functionality of ringing a bell on the visitor chat window page. So when the visitor rings the bell, it is supposed to ring on the operator's machine. Now i have the below mentioned code... This works fine on a local environment, but when i uploaded this to my server, it doesn't work...

the logic is as follows... i have 2 pages - the visitor chat window & the operator chat window...

When the visitor presses the bell icon on the visitor chat window page, i write his ID & Is Belled flag onto to an XML file.

Now on the operator side i check continuously for correct operator receiving the ringing. Then i am calling the sound function on my server. No plug ins are used...

string soundPath = "";
soundPath = "http://"+Request.ServerVariables["HTTP_HOST"]+"/images/LiveChatImages/ringout.wav";

System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer();

myPlayer.SoundLocation = soundPath;
myPlayer.Play();

i am using the soundplayer class in asp.net 2.0

another code i also tried with no success is below:

public void PlaySound()
{
string soundPath = "";
soundPath = http://"+Request.ServerVariables["HTTP_HOST"]+"/images/LiveChatImages/ringout.wav";

WSounds ws = new WSounds();

ws.Play(soundPath, ws.SND_FILENAME | ws.SND_ASYNC);

}

public class WSounds
{
[DllImport("WinMM.dll")]
public static extern bool PlaySound(string fname, int Mod, int flag);

// these are the SoundFlags we are using here, check mmsystem.h for more

public int SND_ASYNC = 0x0001; // play asynchronously

public int SND_FILENAME = 0x00020000; // use file name

public int SND_PURGE = 0x0040; // purge non-static events

public void Play(string fname, int SoundFlags)
{

PlaySound(fname, 0, SoundFlags);

}

}

Anybody can help me with my problem... both these codes are working in my local system ... but none work on the server. Can anybody point out where i am wrong?

Thanks & regards,

This is always a sign that you're confusing what happens on the client and on the server.

If you're doing it on the server, why not use a local path to the file ?

Can you send the mail in html format and just use a simple mailto:

I'd be surprised if you are able to 'automatically' send emails from an embedded script. There are some security issues there if you think about it.

How do I get a control into my ToolBox

I'm trying to use a control I've downloaded, the vbAccelerator IconComboBox[^], but I can't get it to appear in the Toolbox. On the General tab I open "Choose items...", browse to the dll, and select it. I click OK, and the dialogue closes but the control appears nowhere. If I do another "Choose Items..." I see the control is still checked, as if it should be in the Toolbox, but I can't find it anywhere,

OnCheckedChanged not firing

Hi,

This is the weirdest error. I have several checkboxes on my page, and they all are defined the same way but the problem is only for one of them. The problem is that when I deselect the checkbox a postback will occur but the event will not fire.

The code for the checkbox is straight forward:

<asp:checkbox id="CheckBoxId" runat="server" oncheckedchanged="CheckedChangeFunction" autopostback="true" validationgroup="MyValidationGroup" text="My text" />

Found the error. The Enable property was set to false in the page_load (don't ask me why, I didn't write that part =))and for some reason the event was not fired when the box was unchecked.

Hello.
I think the problem is generated span.
Because your checkbox has value on attribute text.
Its populating a span, a input and a label tag.
Event "onchange" is writed on span tag. Its doesnt work.

If u use "onclick" its works.

Good luck.

Sorry i didnt see the date of post.
I hope this answer help someone next time enter here.

in the global.asax file.

my question:
i have a code than run in the session_end method
and this code was no execute. (the code activate other method in other class).

maybe i need to do something before?

for example:

....Session_End....
{
MyClass.MyMethod();
}

Thanks..
Tal

The Session_End method only runs if there is a persistent session object that times out. The session object is only persisted if you have stored any session variables in it.

Also, a common misconception is that the session ends when the browser window is closed, which is not the case. The session ends when the session object on the server times out (by default 20 minutes after the last request).

Use the value property of the textbox element.

how to stop the exeution of a javascript function for few seconds

in vb.net we can stop the fuctionality of a code for some time usig threads.in the same way is it possible to stop a javascript fuction for some time

Re: how to stop the exeution of a javascript function for few seconds

Not really. Javascript is strictly single threaded, so if you pause the script for a few seconds, the browser freezes up totally and does nothing until the script continues.

If you want the execution of a script to continue after a while, use a timeout to start a function:

function work() {
   // do something
   window.setTimeout('work2();', 5000); // continue after 5 seconds
}

function work2() {
   // continue doing something
}

The setTimeout method adds a timer in the window object. After the specified time (5000 milliseconds), the code ('work2();') is executed, which will run the work2 function.
