Or You can try this... by using RegisterStartupScript and pass the variable value from the code.
public void Page_Load(Object sender, EventArgs e)
{
// Define the name and type of the client scripts on the page.
String yourVariable = "yourVariable";
String csname1 = "PopupScript";
String csname2 = "ButtonClickScript";
Type cstype = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the startup script is already registered.
if (!cs.IsStartupScriptRegistered(cstype, csname1))
{
String cstext1 = "alert('Hello World');";
cs.RegisterStartupScript(cstype, csname1, cstext1, true);
}
// Check to see if the client script is already registered.
if (!cs.IsClientScriptBlockRegistered(cstype, csname2))
{
StringBuilder cstext2 = new StringBuilder();
cstext2.Append("script type=text/javascript; function DoClick(");
cstext2.Append(yourVariable);
cstext2.Append(") {");
cstext2.Append("Form1.Message.value='Text from client script.'} </");
cstext2.Append("script>");
cs.RegisterClientScriptBlock(cstype, csname2, cstext2.ToString(), false);
}
}
I hope this helps...
Cheers

In Java the technology is/was called liveconnect. The best manner to do it now would be to write to the document stream new data or to have Javascript make continuous calls to the server.
In your case I would just write the assignment to the file.

Hello everyone,
Currently, I have a simple cache component, which outputs value by an input key. Now I want to design an asynchronous interface to provide BeginXXX and EndXXX function.
Are there any reference documents or any samples/advices of how to design asynchronous interface?
thanks in advance,
George

Start with the async design pattern[^]
Then use background workers, threads, or the thread pool to achieve your operations on a different thread.

Thanks Simon,
I have read up all the stuff you recommended below,
http://msdn.microsoft.com/en-us/library/aa719595(VS.71).aspx
Two more questions about the link,
1.
What means "containers that support waiting on objects"? Could you show me the which API/Class it means please?
2.
For the sample "Do not supply the callback delegate when beginning asynchronous operation" -- I read it but confused. The sample said "Do not supply the callback", but actually in the code callback is supplied here, any comments?
IAsyncResult asyncResult = primeFactorizer.BeginFactorize(
factorizableNum,
ref primefactor1,
ref primefactor2,
callback,
state);
3.
The document mentioned IMessage, actually I have never used it and not found quite good stuff on MSDN. Could you describe or recommend some good stuff to describe what IMessage is and how to use it?
regards,
George

What means "chat sample code"? Could you provide some links please?

I mean chat applications like the windows live messenger.
You can download here in codeproject sample code about it. Chat application need a lot of thread management because of the "clients" (asynchronous or synchronous connections), maybe helpfull for you.
Just type "chat" in search textbox up in this page, you will get lots of articles. I dont really know the best for you, better open all and collect the code you need for your project.

Thanks nelsonpaixao,
Do you have any good stuff to recommended? I have found some but not interested in UI. I do not need UI. If there are some samples or documents which describe how to implement asynchronous pattern will be great!
Any recommendations?
regards,
George

i would like my application redirect after login.
Url: http://mySite.com/Login.aspx?ReturnUrl=http%3a%2f%2fmySite.com%2fpage.aspx%3f%26pid%3d1111%26%23Write
But don't know why the application return a error: A potentially dangerous Request.QueryString value was detected from the client (ReturnUrl="...1111&#Write").
Could anyone help?

I think that it's the http:// part of the data that it reacts on. Try to use a relative url instead of a fully qualified url.
Otherwise you can turn of ValidateRequest in the @Page directive.
Despite everything, the person most likely to be fooling you next is yourself.

Because some idiot thought it would be fun to make ASP.Net websites crash randomly. This ill-designed "protection" is causing more harm than good in each and every website where it's not turned off.
And now it seems in ASP.Net MVC 2 it can't be turned off. I've already modified web.config and this idiotic message still appears.
Hey dude, I ain't ever gonna include that value unescaped in the HTML, shut the heck up!

Greetings to all!
I have a genric list of UIElements.
A Method passes me two variables:
the direction represented by an integer (+1 or -1)
and the type of the last used object in the list.
I need to find out the index of the last object and get the next one.
eg.:
List<uielements> _list = new List<uielements>(){new Dialog1(), new Dialog2(), new Dialog3()};
internal UIElement GiveNavigationItem(int p, Type lastElement)
{
var result = from o in _list
where o.GetType() == lastElement
select o;
return _list[result + p];
}</uielements></uielements>
Thank you in advance!

Your using generics right?
You need to replace all the "<" and ">" signs in your post with "<" and ">". There's two buttons below the text box to help you. this will make your post easier to understand.

Unless I completely misunderstand what you want, just use this to get the last index:
int lastIndex = _list.Count - 1;
I'm not sure how you can get "the next one" if you're starting at the last index, because there is no "next one".

Let's say I have the List with 5 Elements.
Bound is the one with the Number 4 and I receive the command "+1"/"oldType(element4)"
So I need to check which is the Index of oldType in the list (it's 4) and check if there is a 5 as well.
Yes, it is, so return the Element with the Index 5.
Now I have Number 5 bound and reveive a command "+1"/"oldType(element5)"
Check again the Index of the oldType I find out it's 5.
Now check again if there's a 6 -> no, so keep the old Control.
Otherewise -1 would work.
This lokks like this:
(-) [Container] (+)
and the Control is loaded inside the Container. + gets the next one (if available) - the previous one
Anyway I got my hint for this problem alreadyand I could solve it. Thank you for your help.

here you go:
static UIElement GiveNavigationItem(int p, Type lastElement)
{
var result = (from o in _list
where o.GetType() == lastElement
select _list[_list.IndexOf(o) + p]).FirstOrDefault();
return result;
}

Thank you! That solves my problem!

Well Denver,
If you do a little searching yourself on CodeProject it will give you numerous solutions in a couple of seconds.....
But since I'm already answering your request, here we go:
have you tried the following:
Make a new class that inherites from panel control.
Override the OnPaintBackground and OnPaint methods.
Setting the ControlStyles.DoubleBuffer property on the panel might do the trick as well.
This site might help too:

Happy coding.

Assume this function:
private void Changing(int[] is, int i)
{
is[0] = 100;
i = 100;
}
When I call Changing in Main:
static void Main()
{
int[] is = {0, 1, 2, 3, 4};
int i = 0;
Console.WriteLine(i);
Console.WriteLine(is[0]);
Changing(is, i);
Console.WriteLine(i);
Console.WriteLine(is[0]);
}
is changed but i didn't, why?

Arrays in C# fall in the category of reference types. Like any other reference type, an array object refers to a memory space allocated on the heap.
If you want to deep knowledge then go to Google for Value Type vs Reference Type.

Hi, I am using VS C# 08 Express Edition and I have a personal web browser that I've almost finished, and on Form1_Load the web browser will goto my custom homepage. But I am not sure how to go about this. I want to have the HTML file that I've created to either be installed with the program when someone installs my program or have it embeded into the .Exe file somehow, is either way possible? Can somebody please explain how to do this? Thanks in advance 
regards,
jt
