hi men
how can I make validation to accept specific input
such as in my text box Only email is valid input
aaa..@dddd.com
like that
|
|

well one option would be to check for a '@' character in the textbox.Text string, then see if there is atleast one '.' character after the '@' character.
something like:
string text = TextBox1.Text;
string[] split = text.split('@');
if(split.length == 1)
{
if(split[1].Contains('.'))
}

Have you ever heard of Regular Expressions?
In fact, Regular Expression validators(as the name suggest) can do this with lot ease.

<asp:TextBox ID="tbEmail" runat="server" ValidationGroup="Register" />
<asp:RegularExpressionValidator ForeColor="Red" ValidationGroup="Register" ControlToValidate="tbEmail" ErrorMessage="Email Address is not valid." ValidationExpression="^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$" EnableClientScript="true" ID="RegularExpressionValidator1" runat="server" Display="Dynamic" />
Or you could create a custom validator that will do the validation for you and set your page IsValid property to true or false depending whether valid or not.

There are women on this site, too.
There's a control built in for validating text, or, as someone said, you can use regex.

This is a javascript email validator. This validator can be customized to allow any domain name.
// Email Validator
function emailCheck (emailStr) {
/* The following variable tells the rest of the function whether or not
to verify that the address ends in a two-letter country or well-known
TLD. 1 means check it, 0 means don't. */
var checkTLD=1;

var knownDomsPat=/^(com|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|info|pro|museum)$/;
/* The following pattern is used to check if the entered e-mail address
fits the user@domain format. It also is used to separate the username
from the domain. */
var emailPat=/^(.+)@(.+)$/;
/* The following string represents the pattern for matching all special
characters. We don't want to allow special characters in the address.
These characters include ( ) < > @ , ; : \ " . [ ] */
var specialChars="\\(\\)><@,;:\\\\\\\"\\.\\[\\]";
/* The following string represents the range of characters allowed in a
username or domainname. It really states which chars aren't allowed.*/
var validChars="\[^\\s" + specialChars + "\]";
/* The following pattern applies if the "user" is a quoted string (in
which case, there are no rules about which characters are allowed
and which aren't; anything goes). E.g. "jiminy cricket"@disney.com
is a legal e-mail address. */
var quotedUser="(\"[^\"]*\")";
/* The following pattern applies for domains that are IP addresses,
rather than symbolic names. E.g. joe@[123.124.233.4] is a legal
e-mail address. NOTE: The square brackets are required. */
var ipDomainPat=/^\[(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})\]$/;
/* The following string represents an atom (basically a series of non-special characters.) */
var atom=validChars + '+';
/* The following string represents one word in the typical username.
For example, in john.doe@somewhere.com, john and doe are words.
Basically, a word is either an atom or quoted string. */
var word="(" + atom + "|" + quotedUser + ")";
// The following pattern describes the structure of the user
var userPat=new RegExp("^" + word + "(\\." + word + ")*$");
/* The following pattern describes the structure of a normal symbolic
domain, as opposed to ipDomainPat, shown above. */
var domainPat=new RegExp("^" + atom + "(\\." + atom +")*$");

different pieces that are easy to analyze. */

even fit the general mould of a valid e-mail address. */

//alert("The username doesn't seem to be valid.");
return false;
}

return false;
}
}
/* domain name seems valid, but now make sure that it ends in a
known top-level domain (like com, edu, gov) or a two-letter word,
representing country (uk, nl), and that there's a hostname preceding
the domain or country. */

//alert("The address must end in a well-known domain or two letter " + "country.");

I want to define a color array based on the system defined color such as Color.Blue, Color.Green and so on.
that is: Color [50] color_array=new Color [50]
but I don't know how to define it in an easy way so that I don't need to write all the available color by hand, because if I want to write all, it will take so long time, is there any simple way? thanks.

you can iterate over the Colors array that exists already, or use loops to build colors with steadily increasing r/g/b values.

The color's that are availableare actually static properties of the Color class, so I think you may have to use reflection.
There's not *that* many, it'd be easier to do it by hand and your program will run much quicker IMO.

He could always write a microapp that used reflection to write out a hardcoded list to include in his main program.

you can use the KnownColor[^] enumeration to do stuff like this:
foreach (string color in Enum.GetNames(typeof(KnownColor)))
{
}

This is not the HL7 support site.
Beyond that, if you're working with HL7, it sucks to be you. Of course, you could be working on AHLTA, and that sucks even more.
