In using javascript...
i'm trying to read content from an html document within an iframe cause I want to reformat the content.
In IE6 I can have the embedded web page set the status bar, and then I get read that from a script in the main page. (Or I can set the clipboard data and read the clipboard from a script).
None of this works in Mozilla 1.6 (Mozilla/5.0). But can something be made for Mozilla that will take data from an iframe's content and feed it into a variable of the web page?
VB Script could be okay or maybe a java applet available across the internet.
Thanks.

In your main file, you could have something like:
<html>
<head></head>
<body>
<form action="#" method="post">
<input type="button" value="click me" onclick="alert( aVariable );" />
</form>
<iframe src="o.html" width="300" height="300">
</body>
</html>
and, in o.html, you could have
<html>
<head>
<script type="text/javascript">
parent.aVariable = 500;
</script>
</head>
<body>
Moo.
</body>
</html>
The HTML file in the IFRAME sets a JavaScript variable in the parent document that the parent document can access.

Thanks. I hadn't tried that.
Anyhow that does work if I put both files on my web server.
But I didn't mention something that has seemed to gain more significance...
The web page in the IFRAME is at a different IP addresss. This seems to stop the transfer through the aVariable -- homeland security or just internet web browser security issue.

That's right. You can't access information across windows that have different server endpoints. I know of no work-around for it. And, if I found one, I'd tell the browser's author to get them to close the security hole!

I was able to put the following into the html document called by the iframe:
window.status="test data"
Since IE6 has only 1 status bar text buffer the text can be read from the main html.
Mozilla seems to give each opened html document a separate status buffer.
I may not have to rely on a trick like this, but I was still seeing if there is a solution.
Now if everything were originating from the same web server, this probably would be easier to solve...

Hai ,
I am having a html page. Inside I am having a textbox, a dropdown with static values and a html button.
I need to do a searching when user specify some text(piece of text) in side the text box and click the button. The searching should do inside my specified folder for some word documents.
Suppose I am having a word doc 'dem.doc' inside the folder C:\NewFolder.When user specify demo in the given text box, and clik the button, I need to open the specified word doc.
Is it possible by using only html and or javascript.
Please show me the right way.
Thank You,
Rahul.P.Menon

 The following code will hopefully do what u want:
function openWordDocument()
{
specificFolder="c:\\NewFolder";
var fso;
fso = new ActiveXObject("Scripting.FileSystemObject");
if(fso.FileExists(specificFolder+"\\"+f1.t1.value))
{
document.URL=specificFolder+"\\"+f1.t1.value;
}
else
{
alert("File does not exist");
}
}

A quick question:
given the following html-fragment:
<div id="mydiv">
<input type="text" value="abc" id="text1" name="text1" />
</div>
then
element = document.getElementById("mydiv");
var my_data = element.innerHTML;
if I do alert(my_data);
I get "<input type="text" value="abc" id="text1" name="text1" />"
if now I change the value on the window and make it "xyz" and do an alert,
IE gives me : "<input type="text" value="xyx" id="text1" name="text1" />"
but Firefox still gives: "<input type="text" value="abc" id="text1" name="text1" />"
how can I fix (or unfix) so firefox also gives me xyz? Only using innerHTML, as I do not want to go the dom way for this problem.

Easiest way, put this before the code that retrieves innerHTML:
var text = document.getElementById('text1');
text.setAttribute('value', text.value);

Thanks. That worked.

Hi, everybody!!
I'm doing a project on C# web application. I need to design a web page and a search engine. I need to design a search engine using the calendar to select the particular date we have click. I have drag and pull the calendar icon. Anyone could tell me the code that if i select on the date i've choose it will show me the database. Anyone who can help me with this.Thank! Your help will be appreciated..
Cheers!

Hi there,
What you might need to do is to create an event handler for the SelectionChanged event of the Calendar[^] control. In the event handler, you can get the selected date from the SelectedDate property and execute an SQL command to query data. If you don't know about the ADO.NET, then the documentation[^] can get you started.

Hi,
I am after some source that generates obsured images of random alphanumeric sequences as a test for human user.
There was something on The Code Project that did this but I lost the link and cannot find the artical.
I think it was either APS or JSP ?
Many thanks in advance.

Hello,
I have done such a task in my project. Try following.
Dim b1(file1.PostedFile.InputStream.Length - 1) As Byte
Dim b2(file2.PostedFile.InputStream.Length - 1) As Byte
file1.PostedFile.InputStream.Read(b1, 0, file1.PostedFile.InputStream.Length)
file2.PostedFile.InputStream.Read(b2, 0, file2.PostedFile.InputStream.Length)
Dim strimage1type = file1.PostedFile.ContentType
Dim strimage2type = file2.PostedFile.ContentType
Dim parmBlob1 As New SqlParameter("@image1", SqlDbType.Image, _
b1.Length, ParameterDirection.Input, False, 0, _
0, Nothing, DataRowVersion.Current, b1)
Dim parmBlob2 As New SqlParameter("@image2", SqlDbType.Image, _
b2.Length, ParameterDirection.Input, False, 0, _
0, Nothing, DataRowVersion.Current, b2)
cm.Parameters.Add(parmBlob1)
cm.Parameters.Add(parmBlob2)
Might be helpful.

Hi,
Can we add web user controls to the intellisense in visual studio .net.
Thanks
Muzammil Ahmed

In the VS 2003, the web user control only supports the intellisense in the code editor, while the VS 2005 supports both in design view and in code editor.

Help!
I would like to know. I am running VS 2005 beta with SQL 2005 beta. When running the Website Admin tool to create roles and users the site keeps on saying enter a different password. I do not know how to get past that.
Does anyone else have this problem?

I have a web site that I open on a remote server over a mapped network drive in VS2005.
It has subdirectories about three or four levels deep, with maybe 100 directories altogether.
When I try to build the web project, I get the following error:
W:\rootdir\subdir\subdir\subdir\subdir\web.config(0): Build (web): An error
occurred loading a configuration file: Failed to start monitoring changes
to 'W:\rootdir\subdir\subdir\subdir\subdir' because the network BIOS command
limit has been reached. For more information on this error, please refer to
Microsoft knowledge base article 810886. Hosting on a UNC share is not
supported for the Windows XP Platform.
I referred to the kb article and did what it said, and even restarted the computer. I am hosting on a mapped drive, not a UNC share.
Is there any way around this? VS seems to be monitoring changes on every single directory in the web, which is a large number of connections.
If I try to "Exclude from project" all the files I don't need ASP.NET to deal with, they get renamed with a ".exclude" extension - which is worthless.
Arrrgh!
Thanks
Mike

Hi,
When we are using XmlHttpRequest to get and submit data with the webserver, please advise what would be the modus operandi to handle concurrent requests.
We would be using a syntax similar to
req = new XmlHttpRequest();<br />
req.onreadystatechange() = function()<br />
{<br />
<br />
}
This req object would be erased before it the function returns for the next call.
How would be go about declaring dynamic req object in JavaScript.
Any pointers...
