@PAYEENAME char(20),
@PAYERINITIAL char(20),
)
AS
DECLARE
@ReturnValue int
INSERT INTO PAYEE (CUSTID, PAYEEACCNUM,PAYEEACCTYPE,PAYEENAME,PAYERINITIAL, REF)
VALUES (@CUSTID,@PAYEEACCNUM,@PAYEEACCTYPE,@PAYEENAME,@PAYERINITIAL, REF)
IF @@ERROR<>0
BEGIN
PRINT 'ERROR'
SET @ReturnValue=1
RETURN @RETURNVALUE

Web Forms :: Generate A Unique Identifier Or Reference Number Based On A Format?

Jan 22, 2010

I need to generate a Unique Reference number that has 7 digits.

It should be formatted in the following way:

1st: B (Ball), G (Gift), C (Cat)

2nd: represents year of booking A(2010), B(2011),C(2012), etc

3rd: represents the month of booking J(Jan),F(Feb),M(Mar),A(Apr),Y(May), U(Jun), L(Jul),G(Aug), S(Sep),O(Oct),N(Nov),D(Dec)

4th: days of booking A(1st) - Z(26th), 1(27th) - 5(31st)

5,6,7th: These are counters for the number issues each day. Each can be A-Z,0-9 giving a total of 46,656 combinations. So 0 is first, then 1, 2, 3, 4, 5, 6, 7, 8, 9, A-Z, then 00 to 0Z, then 10 to 1Z, then 20 to 2Z, etc

Now , the 1st Digit is a Character that I generate based on a condition and that shouldn't be a problem.

Web Forms :: Unique Id Not Being Set Early Enough On User Control?

Jan 14, 2011

I have a UserControl (basically a custom menu) that has some properties on it that I store in the view state. My pages may have multiple instances of this control, so to keep the values unique in the ViewState I concat my names with the control's UniqueId. However, when the properties are set the UniqueId does not exist yet, it returns the control's ID, in the case below, mnuFormNote. So then later when they are read it doesn't return the correct value because later the UniqueID is set so it attempts to read from a different ViewState location.

So, my question is am I doing something wrong or just missing something? If not, is there a way around this?

[Code]....

So when the page loads, and ShowEvents is set to False the property set actually does this: ViewState("mnuFormNoteShowEvents") = False. But later, when I attempt to Get the ShowEvents value it is doing this: ViewState("ctl00$ctl00$mstrContent$iepointMasterContent$dlForms$ctl00$dlStudentForms$ctl00$mnuFormNoteShowEvents"), which is nothing, so it returns the default of True. I need this value to be unique.
