I having a weird problem now... all the function run correctly, but the msgboc just didnt show out... it may make my user confuse is the function been run or not.
when i test it the function just run correct, save item if there is no record of it which mean Add new record, if there is record in it then dont perform anything.
Do
On Error Resume Next
temp = rs![custNO]
rs.MoveNext
Loop Until (rs.EOF)
If ccustno.Text <> rs![custNO] Then
rs.AddNew 'Add detail to record
rs.Fields("CustNo") = ccustno.Text
rs.Fields("Customer") = UCase(ccus.Text)
rs.Fields("Area") = UCase(carea.Text)
rs.Fields("Address") = UCase(caddress.Text)
rs.Fields("Tel") = cphone.Text
rs.Fields("Fax") = cfax.Text
rs.Fields("Name") = UCase(cattn.Text)
rs.update 'update u record
rs.MoveFirst
MsgBox ("Customer Information Recorded")
Else: MsgBox ("Customer already been create, please use the UPDATE function for update"): Exit Sub
End If
---
i have edit the code, it works well now 
'move the return the database at first data if not it will have no current record error
'using DO loop to set the value to temp then compare it again and perform action with another ifelse outside the loop.
rs.MoveFirst <br />
Do<br />
If ccustno.Text <> rs![custno] Then<br />
ElseIf ccustno.Text = rs![custno] Then<br />
temp = rs![custno]<br />
End If<br />
rs.MoveNext<br />
Loop Until (rs.EOF)
<br />
If ccustno.Text <> temp Then<br />
....

You are mistaken, the function doesn't run correctly at all.
When you exit the loop the recordset will always be read to the end, so when you try to use rs![custNO], you will get an error as you can not read anything from the recordset beyond the last record.
You are using On Error Resume Next, but you are not checking for errors anywhere, which means that you silently ignore anything that goes wrong.

ok now i have cancel the on error resume
I having error on handle my error control, when user try to save a new data which alreayd been create in database then i will show an error msg out with IF -ELSE but i not sure y the error keep pop out ask me to debug as it said there is duplication in the database.
I have already put the If else statment to control it ....but not really work...
If ccustno.Text <> rs![custno] Then
rs.AddNew 'Add detail to record
rs.Fields("CustNo") = ccustno.Text
rs.Fields("Customer") = UCase(ccus.Text)
rs.Fields("Area") = UCase(carea.Text)
rs.Fields("Address") = UCase(caddress.Text)
rs.Fields("Tel") = cphone.Text
rs.Fields("Fax") = cfax.Text
rs.Fields("Name") = UCase(cattn.Text)
rs.update 'update u record ------->highlight ERROR
rs.MoveFirst
MsgBox ("Customer Information Recorded")
ElseIf ccustno.Text = rs![custno] Then
MsgBox ("Customer already been create, please use the UPDATE function for update")
Exit Sub
End If

What code do you use to make that check?
campbells wrote: but i not sure y the error keep pop out ask me to debug as it said there is duplication in the database.
The reason is very simple. You get the error message for the reason that is clearly stated in the error message. You are trying to create a duplicate in the database.

When i put the "on error resume next" my function work well REcently i just use that for temporary atleast my function work well.., cause i see the result myself. When user save something that already been save it will not save any change, if the record no exist then Add the new record. But the problem here is it always pop up the msgbox that record been save even when the record didnt save at all. suppose it have to pop up the other msgbox about the data didnt save in my elseif statement ccustno.Text = rs![custno].

It only works well as long as there is no error. If there is an error, it doesn't work, but you don't notice it. At least not until later...

That is because you are ignoring the error. Handling errors by ignoring them is not a good way to handle them. That is like turning the radio up when the car starts to sound funny...
But the problem here is it always pop up the msgbox that record been save even when the record didnt save at all.

This just doesn’t make any sense what so ever.
[Warning This is Pseudo Code!] 
Why not do a
Select Count(CustNo) as CountOfCustNo from Table where CustNo = ccustno.Text
[The above sql query doesn’t protect again SQL injection attacks.]
Then you can just do a simple
Int iCount
iCount = rs.Fields("CountOfCustNo”).Value
if iCount > 0 then
Msgbox “Customer Number in use”
Else
Update the record
I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

Yes, that works, but I have seldom seen it done in such an inefficient way...
Instead of looping throught the entire recordset, select the record you are interrested in. Then you just have to check if the recordset is empty or not.

yes! thanks for telling me... i just edit it ,it almost like my search function .... more easy way... anyway having good experience :P
Dim recselect As Recordset
Dim sql
sql = "select *from Customer where [custno]=" & "'" & ccustno.Text & "'"
'On Error Resume Next
Set recselect = DB.OpenRecordset(sql, dbOpenSnapshot)
If recselect.RecordCount = 0 Then
rs.AddNew 'Add detail to record
rs.Fields("CustNo") = ccustno.Text
rs.Fields("Customer") = UCase(ccus.Text)
rs.Fields("Area") = UCase(carea.Text)
rs.Fields("Address") = UCase(caddress.Text)
rs.Fields("Tel") = cphone.Text
rs.Fields("Fax") = cfax.Text
rs.Fields("Name") = UCase(cattn.Text)
rs.update 'update u record
rs.MoveFirst
MsgBox ("Customer data saved")
Else
MsgBox ("Customer already been create, please use the UPDATE function for update")
End If
BUT will this cause SQL injection attack??

Hi,
I am wondering if I can have a drop down list launching a sub without autopostback on?
I need it to populate another DDL when an item is selected...
The reason I want it to happen without autopostback on, is, I have so many many active items on page it takes forever to populate the second drop down list, and redisplay a datagrid...
Unacceptable, takes way too long...
So, in short: how to launch a sub from the DDL when selected index changed, without autopostback on (or if you have another suggestion on how to prevent whole page to reload)

thx for reply,
I'll have to look more at that ajax thing..
But for now, is there no asp element i can put the grid (and other panels/controls) in to prevent it from "blinking" every time a value in my drop down lists changes?
Or no vb.net solution to preventing this, and really have control over what happens on a selectedindexchanged..?

Not an official release version but you could try using the UpdatePanel component in the latest Atlas[^] CTP (which would be implementing Alax style controls).
Bear in mind that because the Atlas stuff is still pre-release it may be buggy & you shouldn't use it for any mission critical solutions. Apart from that i think the license agreement only runs till September 2007 (i'm open to correction there).
You could try doing it via client side scripts but that would probably be ridiculous.

A client side script launching a server side vb sub (which would then populate the next DDL)? that possible? (don't think so, but it would be nice...)
I guess I'm gonna look at that atlas thing, I failed to install/get it to work on my porject last time I tried it...
Still waiting if someone has a miracle solution like "just put your datagrid in <asp:[magicantipostback[> !"
