String to smalldatetime errors VB6 app to SQL Express

We have 2 vb6 applications.
Both used to use SQL 2000 Standard.
Both databases were recently moved to SQL 2005 Express.

Both application use the same code to convert textbox values to sql date time values.

Public Function SQLDate(dtValue As Date) As String
10        SQLDate = "'" & Format(dtValue, "YYYY-MM-DD") & "'"
End Function

SQLExec = "UPDATE tbl SET CreateDate = "  & SQLDate(Text1.text) & " WHERE User = 1"
Adoconn.Execute SQLEXEC

Application 1 has no problems doing these updates.
Application 2 on the otherhand gives an error.
The conversion of char data type to smalldatetime data type resulted in an out-of-range smalldatetime value.

I get the same error in both dbs when if copy'n'paste sqlexec into query analyzer. When the quotes around the date are removed, it works fine......

Application 2 works when I alter the date format to:

Public Function SQLDate(dtValue As Date) As String
10        SQLDate = "'" & Format(dtValue, "DD-MM-YY") & "'"
End Function

But only works on my development machine and not on a production machine.

I have tried changing the datatypes to DateTime instead of SmallDateTime to no avail.

What's going on here and how can I resolve it.

Thanks!

Hello,
You can always use sql syntax like this:
SQLExec = "UPDATE tbl SET CreateDate = Convert(smalldatetime,"  & SQLDate(Text1.text) & ",105) WHERE User = 1"
Adoconn.Execute SQLEXEC

105 parameter for Convert T-SQL function is for second version of your SQLDate function but you can find something useful in documentation of Convert T-SQL function.

Your problem is probably because of using different national and region settings on laptop and sql server.

! - date format may different in development  and production(means in development  server may dd/mm/yyyy format  and in production may 'mm/dd/yyyy')

Fooky,
Your idea might work but I have a lot of date fields and I would have to make many changes in the application.
It also still doesn't explain why the exact same code does work from the other application.

Binuth,
My development machine, production machine and db server all have the same regional settings.

Doesn't work in SQL management
UPDATE tbl SET CreateDate = '2008-10-30 12:32:42'  WHERE User = 1

But htis does (no quotes)
UPDATE tbl SET CreateDate = 2008-10-30 12:32:42 WHERE User = 1

So I change the SQLDate function to not include any quotes.

Public Function SQLDate(dtValue As Date) As String
10        SQLDate = Format(dtValue, "YYYY-MM-DD")
End Function

No difference. :-( ??

Got it !!
I compared the 2 application databases using
DBCC UsersOptions
Found that the database for applcation 1 had date format YMD.
So I just changed the date format of the other applications databse to the same.
Set DateFormat YMD
