To do that, you would write it in javascript to run on the client.

Hi friends
I want show an image that sent from a webcam through internet. If it was windows form, I used picturebox. But in web for, what I can do?

You need to use an img tag and update the image either via AJAX or by making the page auto refresh.
Unless you can point to a stream that you can connect to with windows media player.

Hi all,
i want to erase the textbox values when user presses browser's back button.
i have tried erasing the values before redirecting the page but its not working ..
Can anybody guide me how to achieve this......

One way is to not store values in viewstate at all, and just getting them from the URL. How are they populated now, is it just viewstate ?

What error are you getting?
The current situation is that you can access "a.html" under this virtual directory "http://localhost/web/learning/reportdesign/a.html" but you can't access your project.
Where is your project? is it under "http://localhost/web/learning/reportdesign/"?
Try to open the project file (e.g: ".csprj") not solution file. and check the path in your project file...

You should probably contact with their support.... As this control is not the standard controls of .NET framework, we all here might not have any experience in using that control.

How to convert datagrid in excel format in asp.net.
|
|
|
|
|
What do you want to do ? You can write the contents of a datagrid to an Excel file on the server end using office interop. You can also send that Excel file to the client if you want to.

i m developing web application in which i m sending and receiving sms through mobile connected with a cable. but sms is not receiving.

You've asked this three times now. You need to talk to the people who provide you with an API for SMS sending/recieving. I don't really see how you can connect to a mobile with a cable, and then run it as a web app, given as your code will run on the server, and the phone will be on the client end.

my dear you want to recive sms through internet so u can use some protocoles

in http you can connect to the smsc (mobile company)and they send to u they message in query string and from your side you can catch them by httplistner

The synchronous model is appropriate if your application should block while waiting for a client request

Using the synchronous model
call the ***GetContext method***
which waits for a client to send a request.
The method returns an HttpListenerContext object to you for processing when one occurs.

Listener.GetContext();

// Construct a response.

// Get a response stream and write the response to it.

***************************************************************************************
***************************************************************************************

In the more complex asynchronous model, your application does not block while
waiting for requests and each request is processed in its own execution thread.
Use the*** BeginGetContext***
method to specify an application-defined method to be called for each incoming request.
Within that method
call the EndGetContext method to obtain the request, process it, and respond.

//For Example we have 20 servers
for (int x = 0; x < 20; x++)

Listener.BeginGetContext(new AsyncCallback(ListenerCallback),this.Listener);

{
if (this.Listener == null) return;
//HttpListenerContext Provides access to the request and response objects used by the HttpListener class.

See, it's because of people like you that certifications are worthless. Just say I had these answers and sent them to you. Do you think you can go into an interview with that certificate, but have no idea how to pass the test ( i.e. not know how to write web apps with C# ) and get a job ?

Hi,
I have a problem with browser back button in my website on production server. I have done lot of googling but cannot find the solution. However browser back button work correctly on local server.
I am using asp.net 1.1 / C#, Window 2003 server and also me website using ssl.
In some pages browser back button works correctly, but in some page it gives the following error.
"The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you.
To resubmit your information and view this Web page, click the Refresh button. "
Any Help would be highly appreciated.

This means you did a postback. The way around this is to redirect on a postback and put the data your form needs to maintain it's state, on the URL.

Hi,
Thanks for your quick response. Actually I am not doing a POSTBACK. I am just clicking the browser back button, so that browser get the page from cache and display it. But it shows that the page has expired.
It works correctly on local server where we have not incorporte ssl certificate. But it shows poblem on server where we have incorporate ssl certificate.
Again thanks for you reply ..

OK, then it's an issue when SSL is on. You didn't say that before.

Hello guys,
I want to update my Access database. I can update all fields of the table except password field.
If i omit password field from the QuerryString, remaining fields are successfully updating. E.g.
QuerryString = "update Users set name=@name,emailid=@emailid,dob=@dob,address1=@address1,address2=@address2,city=@city,state=@state,pincode=@pincode,country=@country,accounttype=@accounttype,boss=@boss where username='ABC'";
This is successful.
But when i add password field to it, its showing syntax error in update stmt. e.g.
QuerryString="update Users set password=@password,name=@name,emailid=@emailid,dob=@dob,address1=@address1,address2=@address2,city=@city,state=@state,pincode=@pincode,country=@country,accounttype=@accounttype,boss=@boss where username='ABC'";
This is showing error:"Syntax Error in Update Stmt."
Can anyone help me?
Thanks,
Nagendra.
