Hi,
You guys would have seen the image cropping tool which has a selection option (marque tool) created in javascript.
[URL="http://marqueetool.net/examples/"]http://marqueetool.net/examples/[/URL]
Like this i want to get all elements under a selection.

For example in windows we have mouse group selection of files and folders by dragging the mouse to select multiple files. Like that i need to get all the elements under a selection in javascript. I can try other gimmicks but if there could be a simple tool then i can speed up my work.

In a window, to select multiple files or folders that are near each other, you may drag the mouse pointer to create a selection around the outside of all the items that you want to include, to do a similar thing in a web page you first create a div and size and position it, then compare it's coordinates to the objects on the page .

That's a good idea.
So, i need to do a recursive dom parsing or to use document.all if it is anywhere on the screen.
or if it is inside a layer for example a table or a div then i get all the elements inside it and have a compare with its left and top properties. That is get the coordinates and check it with the selection boundary. And we can filter out the elements which we need to work on using the className attribute. Nice. This will work. thank you.

There are no built in methods of function, you must create it, in JavaScript yourself. Rather than spending the time and resources to do so wouldn't you think it more efficient to use a pre-built library?

This is not what you were expecting... anyway here i go...
Doesn't asp have an option of sending mail to multiple recipients in one shot like in php?
It has been a long time i have used that.
I could suggest a tedious work around. Have a dll or other com component specially for this which could send mail using smtp. or send mail using smtp by using sockets.

You should be able to get code snippets for this i hope...

Try This,It worked for me

char[] splitter = { ';' };
string[] MailIdTo = txtMailTo.Text.Split(splitter);
string[] MailCc = txtMailCc.Text.Split(splitter);
string[] MailBcc = txtMailBcc.Text.Split(splitter);

MailMessage mailToSend = new MailMessage();
if (txtAuthenticationMailId.Text != "")
mailToSend.From = new MailAddress(txtAuthenticationMailId.Text);
else
mailToSend.From = new MailAddress("XYZ@gebbs.com");

for (int i = 0; i < MailIdTo.Count(); i++)
{
if (MailIdTo[i] != "")
mailToSend.To.Add(new MailAddress(MailIdTo[i]));
}
if (txtMailBcc.Text != "")
{
for (int i = 0; i < MailIdTo.Count(); i++)
{
if (MailCc[i] != "")
mailToSend.Bcc.Add(new MailAddress(MailCc[i]));
}
}
if (txtMailCc.Text != "")
{
for (int i = 0; i < MailIdTo.Count(); i++)
{
if (MailBcc[i] != "")
mailToSend.CC.Add(new MailAddress(MailBcc[i]));
}
}
if (FileUpload1.HasFile)
{
string FileName = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
mailToSend.Attachments.Add(new Attachment(FileUpload1.PostedFile.InputStream, FileName));
}
if (FileUpload2.HasFile)
{
string FileName = System.IO.Path.GetFileName(FileUpload2.PostedFile.FileName);
mailToSend.Attachments.Add(new Attachment(FileUpload2.PostedFile.InputStream, FileName));
}
if (FileUpload3.HasFile)
{
string FileName = System.IO.Path.GetFileName(FileUpload3.PostedFile.FileName);
mailToSend.Attachments.Add(new Attachment(FileUpload3.PostedFile.InputStream, FileName));
}

{

}
if (FileUpload5.HasFile)
{
string FileName = System.IO.Path.GetFileName(FileUpload5.PostedFile.FileName);
mailToSend.Attachments.Add(new Attachment(FileUpload5.PostedFile.InputStream, FileName));
}
mailToSend.IsBodyHtml = true;

Web Services -- start up notifications

First, sorry if this is a numbskull question:

Is there a way to catch a 'start up' event from IIS?

Here is the problem:

I have a significant amount of data to cache when the web-service starts up and I have not found a way to (reliably!) get notified when the web service is first started.

If I could catch that event, then I could do all the data pre-fetches before the first web service caller comes in.

Thanx in advance.

ajax, xml results and ie error "object required"

cjoki1-Apr-10 9:12

Hello all,

This is more of a posting of my findings. I traced the issue I had with an ajax script error. Since I found little information on the web on a fix for it, I wanted to make this post.

The Issue:
I have an ajax call to a script that returns contact information stored in a database. The xml result looks like this

<rs>
  <coname>A Company</coname>
  <addr>123 main st.</addr>
  <city></city>
  <state></state>
  <zip>77001</zip>
</rs>

When the returned information include fields that are empty ie will throw an error "object required" when you try to access the value like...

document.getElementById("city").value = xmlDoc.getElementsByTagName("city")[0].childNodes[0].nodeValue;

...this is the source of the ie error, firefox does not generate an error.

Testing for empty string or null has no effect.

To work around it you can test for an empty sring in the result from the database query and either use a character string to test for in your callback function or leave the value out of the xml and test for undefined. Like..

<rs>
  <coname>A Company</coname>
  <addr>123 main st.</addr>
  <city>-1</city>
  <state>-1</state>
  <zip>77001</zip>
</rs>

<rs>
  <coname>A Company</coname>
  <addr>123 main st.</addr>
  <zip>77001</zip>
</rs>

Anyone else have ideas on this issue, I would like to hear them.

All the Best!

if(xmlDocument.getElementsByTagName("city")){
   if(xmlDocument.getElementsByTagName("city").childNodes){
      alert(xmlDocument.getElementsByTagName("city")[0].nodeValue)
}}

That's just a sorta, the idea is to test
for the object before accessing its property.

the check I was using...

if(typeof xmlDoc.getElementsByTagName("city")[0].childNodes[0] != "undefined")
{
	document.getElementById("city").value = xmlDoc.getElementsByTagName("city")[0].childNodes[0].nodeValue;
}

IE did not complain about the object (childNode[0]) being undefined. Nor did FF. FF just assigned a blank string to city and IE would choke at the assignment and toss the error.

Maybe I could have done this to check if the value is set, but I have not checked if it is even valid.

if(typeof xmlDoc.getElementsByTagName("city")[0].childNodes[0].nodeValue != "undefined")

I now use this and it works fine...

if(typeof xmlDoc.getElementsByTagName("city")[0].childNodes[0] != "undefined")
{
	if(xmlDoc.getElementsByTagName("city")[0].childNodes[0].nodeValue!="-1")
	{
		document.getElementById("city").value = xmlDoc.getElementsByTagName("city")[0].childNodes[0].nodeValue;
	}
	else
	{
		document.getElementById("city").value = "";
	}
}

I check server side for an empty string and instead return a -1 when one is found.

From C++ to Web - which way to go?

Ok so I'm new(ish) to web stuff being predominantly a C/C++ programmer up to now. I'm looking to produce my own website (for fun (!)) to display photos in gallery and slideshow form, I'd like it to be flashy and cool with nice transitions between photos, lots of shiny things, reflections etc ( Poke tongue | ;-P

)

Whats the best route to go down as regards what language(s) to start with?

Not Active1-Apr-10 6:43

1-Apr-10 6:43

The language doesn't really matter, you can do all if with html and JavaScript.

However, it would be an easier transition from C++ to C# and JavaScript since the syntax and structure is very similar.

I would recommend looking at the JQuery as it provides a nice library of useful UI widgets and functions for JavaScript. Silverlight would also get you the very flashy coolness but it has a learning curve for one not accustomed to .NET

You don't need any tools except notepad really. VS will give intellisence if it's setup, but that won't help with learning the language. For that you would need to pick up book or look on the web, plenty of resources there.
