Then they wouldn't be global now would they?

I didn't have a question. I do know though, do you know the difference between the meaning of local and global?

Stop it, the pair of you. There is no excuse for this form of behaviour in the forums. Please refrain from these attacks - they are not clever.

I'm not a stalker, I just know things. Oh by the way, you're out of milk.

Accessing local machine from web page

Is it possible to access local machine form webpage without IE/ActiveX? For example, can I execute an exe file on a local machine? Or, If viewer's machine hosts a webservice, can i invoke it through webpage?

No. Think about it. Would you want some website, written by an unknown party, to run an application on your local systems, say "format c:"

Thank you for the answer i asked before. it is great. i have the same problem with url. just look at the code below.

// open a hypertext link with javascript: scheme to call display function
document.write('')

// print transparent image (use any height and width)
document.write('')

// close link tag
document.write('')

in href link why they didnt take the url. what is the meaning of that code "javascript:display(\' '+(red+green+blue)+'\')" why they take like that? can u expaline it clearly.

If you have the same problem you should ask in the same context, or at least reference the previous questions/answers.

Remember, we are not sitting at the same desk as you, we don't see the same thing you do, so you can't asked a question without some frame of reference or giving a complete description of the problem.

I get the feeling that you have taken someone else's code and are working through it step by step trying to figure out what is happening. I would suggest you get a good Javscript book or online tutorial, and get comfortable with the language before addressing some more complex issues.

I must get a clever new signature for 2011.

Sir, I believe that every student do the same thing, because they think they are making a better time. but the truth is that they are wasting their time and also other's.

I think that may or may not be the case; I have learned lots of useful things by taking someone else's code and working through it. However, I usually start by studying the basics of the language in question.

I have a problem with this code. if you understand this please send me the explantion.
I dont understand the variable intialization. could u please tell me what it means.

var openImage = ""

function getPath(url)
{
lastSlash = url.lastIndexOf("/")
return url.substring(0, lastSlash + 1)
}

regards

Assuming url contains something like "dir/subdir/filename" then you will get the following:

openImage = <IMG SRC="filenamedg
closeImage = .gif" HEIGHT=21 WIDTH=16>

// so putting them together will create the string 

<IMG SRC="filenamedg.gif" HEIGHT=21 WIDTH=16>

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
