Your only option to do that on a simple html page is to use an mailto: url in a form. This will use the mail program on the visitors computer, so it will of couse only work from a computer that actually has a mail program installed with a working email account.

If you don't want to go down the line of developing your own server-sode code for this, and your website is hosted by an independednt ISP, ask them - most offer a cgi script you can utilise to do this.

u can do validation using Javascript.
function IsNumeric(sText)
{
var ValidChars = "0123456789.";
var IsNumber=true;
var Char;

for (i = 0; i < sText.length && IsNumber == true; i++)
{
Char = sText.charAt(i);
if (ValidChars.indexOf(Char) == -1)
{
IsNumber = false;
}
}
return IsNumber;

}

This Javascript function

function chkQty(qty) {
var regex = /^\d+$/;
if ( !regex.test(qty) ) {
alert('Please enter a number larger than 0');
return false;
}
return true;
}

will return true only for +ve whole numbers passed to it, so you can use it to check the textbox entry on submiting the form, or even on the onblur event of the box itself

Use RegularExpressionValidator then open properties and simplye write down \d{0,9} in validation expression property. It will validate on client side.

In addition to what was already written:

If you are writing an asp.net ajay enabled web application then you can use the FilteredTextBoxExtender and specify its type as numeric.

Are you calling your databind method in the page load or something? The method won't get called automatically.

Re: annoying problem

I would change this line:
dgUsers.DataSource = ds
to point to the table you want to bind to.
perhaps it is the first table returned:
dgUsers.DataSource = ds.Tables(0)

I think you are missing AutoGenerateColumns="true"
in your datagrid code in the html.

Problem in mailto:

hi,

i am using mailto: command on my web page.
the problem with this is when i am including the subject in this command and if subject is having '&' then the subject is being truncated in outlook.

please find the code below:

mailto:Webv2test96@executiveboard.com?subject=Message Regarding Leadership Development (ContentId=1118)& Rohit

Output:
Subject line only picks "Message Regarding Leadership Development (ContentId=1118)" and truncates "& Rohit" part.

i want to show all the text "Message Regarding Leadership Development (ContentId=1118)& Rohit" in the subject line in outlook.

Please suggest any workaround for this problem

thanks in advance.

YOu need "" since you have spaces in your subject.

" " (beginning and ending double quotes) are necessary if any spaces are used

Mailto parameter should be preceded by "?" for the first or only parameter and "&" for second and subsequent parameter.

In your subject text (Message Regarding Leadership Development (ContentId=1118)& Rohit), you'll need to replace the "&" character with "%26". "&" is a reserved character used to separate parameter name/value pairs, just like in an HTTP url:

mailto:test@example.com?subject=My Subject&body=This is the body of my test message

This is what your mailto: link will do with "&" replaced by "%26":

Use Server.UrlEncode to encode the string properly for putting it in the url.

This will also encode the spaces in the string, as spaces are not allowed in a well formed url.

Hi
I was wondering if you would be able to give me some general feedback on my latest issue

I have created a user login screen, but now I want to be able to create some sort of authentication, so that I don't require the user to enter there login credentials everytime i need to do somthin in my database.

What is the best way of doing this, would issueing a cookie after succesfully loggin in do the job, so it gives me a constant reference to who the user is, allowing me to pull data from tables that is relevant to them

any help appreciated

boy

Re: Authentication

Have you tried just using Session variables? You could go the cookies route but make sure the password is not in plain text and the cookie is set to expire with in a short time later. Say like 20 minutes or one hour... Just a quick thought...
