You have to show more of your code.
What you describe doesn't make sense if one only looks at the SQL query. An update query doesn't care if the value in the field is null or not, it updates the field in either case.

Ok..this is the exact query i am using....
Function testUpdate(ByVal appId As Integer, ByVal fname As String, ByVal lname As String) As Integer
Dim connectionString As String = "server='(local)'; trusted_connection=true; database='TESTDBfhms'"
Dim dbConnection As System.Data.IDbConnection = New System.Data.SqlClient.SqlConnection(connectionString)
Dim queryString As String = "UPDATE [R_Application] SET [Fname]=@Fname, [Lname]=@Lname WHERE ([R_Application]."& _
"[AppId] = @AppId)"
Dim dbCommand As System.Data.IDbCommand = New System.Data.SqlClient.SqlCommand
dbCommand.CommandText = queryString
dbCommand.Connection = dbConnection
Dim dbParam_appId As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_appId.ParameterName = "@AppId"
dbParam_appId.Value = appId
dbParam_appId.DbType = System.Data.DbType.Int32
dbCommand.Parameters.Add(dbParam_appId)
Dim dbParam_fname As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_fname.ParameterName = "@Fname"
dbParam_fname.Value = fname
dbParam_fname.DbType = System.Data.DbType.[String]
dbCommand.Parameters.Add(dbParam_fname)
Dim dbParam_lname As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_lname.ParameterName = "@Lname"
dbParam_lname.Value = lname
dbParam_lname.DbType = System.Data.DbType.[String]
dbCommand.Parameters.Add(dbParam_lname)
Dim rowsAffected As Integer = 0
dbConnection.Open
Try
rowsAffected = dbCommand.ExecuteNonQuery
Finally
dbConnection.Close
End Try
Return rowsAffected
End Function

There is nothing wrong with that code.
Debug the code and watch where you get the values from, as I suggested in the other thread.

I cant seem to remember how to record keystrokes. Basically i need to use the keystroke value in an IF Statement to say,
if back or delete were pressed then
end if
thanks in advance

The windows form as a KeyPress event that you can look at to retrieve the keystroke.

Here is some code that should work for you...
Private Sub yourtextbox_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles yourtextbox.KeyDown
'Only allow some control keys
If e.KeyValue = Keys.Delete OrElse e.KeyValue = Keys.Back Then
'good key press
Else
e.Handled = True
End If
End Sub
Hope that helps.

use the key down event handler as below
Private Sub txtTendered_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtTendered.KeyDown
If e.KeyCode = Keys.delete Then
do something here
elseif e.keycode = keys.enter then
do something else
end if
end sub
hope this helps

Let me get this straight. You want us to find prewritten code for you, I'm assuming it's a quiz program, so you can pass an exam?? Correct?

Hello,
Does any one have any information for sending e-mail using exchange server 2003.
I am using vs 2005 and need to be able to send e-mail from a windows application and have the exchange server send it to the destination e-mail.
If anyone can point me in the right direction or have some information that will be a great help. I have been told that this is very difficult to do.
Many thank for any help you can give me,
Steve

first you need to import this mail class
Imports System.Web.Mail
Dim mail As New MailMessage
mail.To = anyone@someDomain
mail.From = user@yourDomain
mail.Subject = "message subject comes here"
mail.Body = "body of the message.. could be from a textbox"
SmtpMail.SmtpServer = "MailServerName" 'your real server name goes here
SmtpMail.Send(mail) ' this section is what sends the mail...
this is perfectly fine....i have use it..
the from email account..must exist on the exchange mail server account.. so if you have an account on that server.. use it for the from section or just create a temp account to be used for this purpose..
hope this helps..

Hello,
Thanks for your help. The code i used is below. But I got a warning saying that using system.web.mail is obsolete and system.net.mail is the recommended to be used instead.
Also using the MS Exchange is very slow, i tried to send an e-mail to my hotmail and gmail account it takes more than 10 minutes to get there.
Is there any setting on the microsoft exchange server that need to be set?
Another quick question, is there a way to get the server name and the e-mail account automatically instead of a user inputting in? They can just click the send button.
Many thanks for your time,
Steve

First I would say that it is a bad practice to create and drop real tables from a program. If you are just creating tables for temporary use that is different. Now that I got that out of the way.
Is it not as simple as saying DROP TABLE TABLENAME?

Why?

Well for most DBs you would need to elevated priviledges in order to drop or add any table other than a #temp table.

Your original statement was more general than that. Assume that the user has the appropriate privileges. Why would it be bad practice to drop tables from a database in a program?
