No. I do not mean the voice. I just want to do a chat room like one in bbs. I want do it in ASP. What I type now the other will see it in immediately.

You can't litterally do a *real-time* chat room in ASP.NET. This is not allowed alone atleast. You could develop some type of ActiveX control, but you would essentially need to be able to process data back and forth transparently to the user. The website Wininsider has one of the newest forums I have seen that can suppose this *type* of idea.

Yes, I agree with you. In ASP, you can only refresh in 1 second. If you use VC++ to build a Activex Control, you can do it with WM_TIMER Message. It will make minmum refresh with mili-second level. So it seems as real-time.
It is not difficult I think.

I see the website Wininsider. It is amazing. How could it use asp and refresh can do this ?

Hi, I just see the Wininsider. I think it is not a real-time chat room. I ever see a kind of ICQ, when you just input some char into the txtbox, another one can see it immidiately.
For Wininsider, It will show the message after you send your message. I think it use this method.
When you push send button, it will submit message to the file to display the message and refresh it immidiately. That make your message show up at once.
For the chat room i built, I did not use this method. I just let display file refresh it automatically for each 2 second. Because I also add many function into it. If you use same method as Wininsider, it will make server very busy.
That is what i think.

Basically I think he just using a lot of stylesheets and he is storing the data in a database. Reason being is that I posting a *message* in his chat room about a month ago and when I checked the site last night my message was still there. You could do something very similar as well very easily. Is there something specific that you don't understand?

Greetings,
I am new to javascript, and I am trying to get this code snipet to work that I found in a book.
It complains in my web browser (IE 6.0) that a "Object is Required" on the switch statement.
Any ideas as to what I am doing wrong?
CODE:
====
function ParseXML()
{
documentXML = document.all("c:\\Test.xml").XMLDocument;
divResults.innerHTML = getChildren(documentXML, " ");
}
function getChildren(nodeXML, indent)
{
var typeXML;
switch (nodeXML.nodeType) // get error "Object Required" on this line.
{
....
....
// Rest of code
Thanks in advance for any advice.

I figured out what I was doing wrong, you can't have a file path, but you must use an id instead.
Before script block begins add this:
[XML ID = "TESTxml" SRC = "C:\\Test.xml"][/XML]
NOTE: "[" = Is really the "<",ect. I had to change because otherwise the post wouldn't show up.
Now in the actual script change to:
function ParseXML()
{
documentXML = document.all("TESTxml").XMLDocument;
divResults.innerHTML = getChildren(documentXML, " ");
}
That's it!
I hope this helps someone in the future.

Hey, in the Microsoft.Web.UI.WebControls.TreeView Control (which i had to d/l from MSDN), i'm having trouble with the SelectedIndexChanged event which is supposed to go off when a new node is selected. Here's what i've read so far:
Dynamically added nodes in Page_Load() won't have events, so just to be safe i create all nodes in the Page_Init().
Any advice other than this will be helpful!

Is the AutoPostBack on the control set to True?
|
|
|
|

I believe so, but I've had to put that on the backburner for now, i'll be sure to reply here if I start working on it again (which should be soon, i'm finishing up a more important project right now, so i'm sure i'll be stuck in asp.net land soon enough.)

make sure you put the code which sets the focus, at the end of the page, so that the browser runs it after it has already parsed the control you want to affect.
|
|
|
|
|
...or you can use the <script language=javascript defer> so that the script will run after the page is loaded, or fire the script on the onreadystatechange event

You mean there are other browsers besides IE?

I went into IIS and set the directory security (IP address and domain name restrictions) to Denied Access and then added a group of computers using our ip and subnetmask. I also added my own ip as a single computer. When I did this I can no longer open up my project in .NET properly. It says Web Access Failed. Any suggestions?

I figured it out. Apparently IIS is using inverse subnet masking? All the documentation seems to show the other way around. I had to use
IP Subnet Mask
24.24.32.0 0.0.0.255
instead of
IP Subnet Mask
24.24.32.0 255.255.255.0
which is what all the docs seem to use. Did they change this?
