function ValidateText()
{
var txtVal = document.Form1.Elements["textboxname"].value;
var len = txtVal.length;
for(var i = 0;i<len; i++)
{
if(txtVal.charAt(j) < 'A' || txtVal.charAt(j) > 'Z' && txtVal.charAt(j) <'a' || txtVal.charAt(j)>'z')

You behind code language as C# and use below function. I have verified the output.

static void validname(string[] args)

{

Regex regex = new Regex(@"^[a-z A-Z .]*$");

string input = null;

Console.Write("Enter input: ");

input = Console.ReadLine();

if (input == null || regex.Match(input).Success == false)

{

Console.WriteLine("Invalid input. Try again.");

Console.Write("Enter input: ");

return false

}

return true;

Console.WriteLine("Validated!");

Console.Read();

}

  2.  Add the last code into the BODY of your HTML document  -->

<!-- STEP ONE: Paste this code into the HEAD of your HTML document  -->

<HEAD>

<SCRIPT LANGUAGE="JavaScript">

select distinct DataBase I want to add: SELECT DISTINCT [RIVER SCHOOL].email1 FROM [RIVER SCHOOL]; to the following query in an accrees database but I just can't seem to IsNull([dad]), [mom], IIf([dad]> = "A" And [mom]> = "A", [dad] & " " & "and" & " " & [mom]))) AS ggwname, [River School].Sent, [River School].Dad, [River School].Mom, [River School].Student, [River School].Last, [River School].grade, [River School].Address, [River School].Phone1, [River School].Phone2, [River School].email1, [River School
the database but now I am stuck (again!) Here is what I have table 1- School School name, school number, school address, phone, etc. . . . table 2- Fiscal Report fiscal year, quarter number, school number (look up from other table) revenues, expenses, etc. . . . Now I need to generate a report that shows the "Missing" School that have not turned in their reports for a specific quarter. I have built a help! I have a June 1st deadline! Thanks Try This Query : SELECT S1.SchoolName From School S1, Shool S2, FiscalReport WHERE (S1.SchoolNumber = FisacalReport.SchoolNumber) AND (S2.SchoolNumber = FisacalReport.SchoolNumber) AND a error. Is that where this is supposed to go? Thanks SELECT S1.SchoolName From School S1, Shool S2, FiscalReport WHERE (S1.SchoolNumber = FisacalReport.SchoolNumber) AND (S2.SchoolNumber = FisacalReport.SchoolNumber) AND
the user to. The stored procedure then parses the ; delimited list and enters a userid-school record for each school into the tbl_UsersInSchools table . I was wondering how I could make the while statement at CREATE PROCEDURE dbo.wsp_Roles_AssignSchoolsByUserId @UserId uniqueidentifier, @Schools varchar(8000) AS - - declare a table to hold school names DECLARE @USER_SCHOOLS TABLE ( ID INT IDENTITY (1, 1), SCHOOL char(4) ) - - parse the delimited list of schools into individual schools - - and insert the school names into the user_schools table INSERT INTO @USER_SCHOOLS SELECT VALUE AS SCHOOL FROM dbo.fn_Split( @Schools, ';') - - check to see if table has any records DECLARE @COUNT int SELECT @COUNT = count(*) FROM @USER_SCHOOLS IF @COUNT > 0 BEGIN - - select individual school names and insert them along with the user id - - into tbl_UsersInSchools DECLARE @SCHOOL char(4) WHILE( @COUNT > 0 ) BEGIN SET @SCHOOL = (SELECT TOP 1 SCHOOL from @USER_SCHOOLS) INSERT
