Try pixelLeft
If your trying to get the coordinates of an element relative to the document I believe you will have to iterate each parent element and tally up their TOP values.
It's frustrating being a genius and living the life of a moron!!!

<br />
Dim objMail<br />
Set objMail = Server.CreateObject("CDONTS.NewMail")<br />
<br />
objMail.From = "info@4guysfromrolla.com (4GuysFromRolla.com)"<br />
objMail.Subject = "Email attachment demo"<br />
objMail.AttachFile Server.MapPath ("name")<br />
objMail.To = Request.Form("txtEmail")<br />
objMail.Body = "This is a demo on sending an email with an attachment."<br />
objMail.Send<br />
<br />
Response.write("Mail was Sent")<br />

You should first encode the name because http always convert special symbol like it convert blank space into + sign and also more .
First use server.encode(name)
then pass it as query string
then in the next page first use
name = server.decode(name)
If it not work then
make own symbol like + to replace blank from querystring
and another symbol from the query string
and then in the next page replace these symbol again .

Hi all:
I need to control the vertical scroll position of a page when the user hits an arrow. The problem is that the page is like a list or text area control and the behavior should be like this: only when I'm at the bottom of this list the scroll should go down and not at every hit of the arrow. Every item of the list is a DIV element, so I've intended to scroll at a certain position depending on the DIV viewed but I can't manage to work it. How can I know if the DIV is within the viewed area?
I dont't know if that's the best way to do it so if you think there's a better way it'll be welcome.
Thanks,
Marc

I have a search page that has a form that only works half way when I use "GET" and the other half only works when I use "POST"... does anyone have any ideas???
Thanks in advance
|
|
|
|
|
I'm not sure I know what your saying...but...
If you mean some of your POST/GET variables are not being submitted to the server...
You should ask your hosting company or check the config's to see if maybe there is an option which limits the amount of GET/POST data allowed to be submitted - on the server side (ie: PHP you may want to look at the php.ini)
Cheers

Hi, i will be launching a site on which i will have a birthday reminder service along with some other features. Site is being made with the help of ASP and MSAccess. its birthday reminder service is a bit similar to that of birthdayalarm.com. Now if you go to www.birthdayalarm.com you will notice that when it gives you an option to add birthdays to your list, it allows you to get access to your msn list on that very site..a user just has to enter his msn/yahoo id and password on that site and then it shows his full contact list, and then with just one click it can e-mail all those users in the contact list. I want that kind of a system with which users on my site can have access to their msn and yahoo contact list...after they provide their user id and password. Does someone has any idea on how that thing can be made available on my site...any help would be greatly appreciated as its a really important part of my site. Any help (specially with some detailed instructions) would be greatly appreciated.

Hi, Everybody,
I have a question about how to send an email with attachment, here is it:
We can just give a string of the filePath+FileName to AttachFile method, and then send it by using CDO message object. My question is where is the file located? is it on the server of on the client side.
The client side I mentioned aboved means, I create an ASP page where the user can choose the files he/she wants it appears on the EMail. This way the file is on the client side(internet user's pc). Can we just use the file path or we have to upload the file to the server first and then use the server's file to attach it to the email?
Thanks a lot!!

The email is sent in the server, so you have to upload the file to the server and then attach the file in the server to the email.

Hi,
Thanks very much for your answer.
I have one more question:
when I use the following code send the email, I got an Error like this:
Error Type:
CDO.Message.1 (0x8004020A)
The SMTP server name is required, and was not found in the configuration source.
code:
Set Msg = CreateObject("CDO.Message")
With Msg
.To = "careers@integrarx.com"
.From = myRequest("email")
.Subject = "Applied Form"
.HTMLBody = htmlBody
.AddAttachment SavePath
.Send
End With
set Msg=nothing
the code works very well without the attachment, Would you please tell me why and how to fix it.

Hello,
I have 3 HTML textbox controls with the same name & 3 button controls on the page. So it creates an array for textbox controls when I want to refer it in client Javascript. I want to hide one control at a time based on certain condition.
If I click 1st button, I want to hide 1st textbox. If I click 2ns button, I want to hide 2nd button & so on.
Can somebody help me in doing this?
Thanks

i have just begun to learned jsp and java recently, so have the question below:
Situation:
My boss asked me to do a project for doing online data mining.
He requested the thing below:
1. Write a webpage by jsp with some textfield or pull down meun to get the parameter for getting the opinion and the parameter needed for the java class.
2. When the user click the buttom in the website, then the java class have to be invoked.
Questions:
1. ask i put the .java in the server, i can simply use cmd and type the following command:
java -Xmx800M P05context 1 1 3 6 F01xyz.txt F10xyz.txt
which F01xyz is the prepared text file for the java class to read and the F10xyz.txt is the output file generated by the P05context.class
but i don't know how to invoke the P05context.class by jsp
My boss have suggested me two ways to do this:
a. write a java virtual class to execute the java program.
but i don't know how to write.
i think conceptualy will be like this :
public class run_java<br />
{<br />
public void run java(parameter1,parameter2....,parameter6)<br />
{<br />
}<br />
}
b. write a javabean in the jsp. and i have try to use this code(at the end of the message:
but the tomcat server reply a internal error to me
how cani do ?
the jsp file-->

uuHai, I am doing a project on claculating the shortest distance between two cities. The problem is I do not have any idea on which programming language should I use. Is it possible for me to use Dreamweaver to create interface and ASP to calculate the distance? Or I need to use JAVA or C++ to do the find the shortest distance function? What is ASP actually? Is it a programming language like JAVA, Visual Basic?
Plz help me...I am really lost... HELP!HELP!HELP! Thanks!

Firstly, where do you get the data to do the calculations?

You could do this if you want.

ASP (active server pages) is basically a script that runs on a web server that returns HTML to the web user.
ASP is typically written in VBScript, although you can also use JScript.
Cheers,
