Me.MyTableAdapter.Update(Me.MyDataSet.MyTable)
This all works fine but I should like to return to the user a MsgBox which displays the count of new records added and/or existing records amended.I know I could count the records in the underlying table before and after the update, the difference being the count of new records. How can I count amended existing records ?

I have the following search code which works fine. However, I have an additional task to do, which is create a count function for the Record found or Record not found. Presently what it does is it searches and if a record is found it displays at the tooltip "Record Found" if not it says "Record Not found". However, sometimes you have 2 or more records. Therefore, the tooltip should say the exact amount of records found.. For example, 3 Records Found or even 5 Records Found. Also if only one record is found it says "Record Found" but if more it should display " 2 Records Found".

I am using a mysql database and I am trying to get the number of results. I should only have 1 result because this is for a username/password login. I tried this
If loginReader.HasRows Then 'do whatever here Else 'do something else here End If
The loginReader gets the results and does the ExecuteReader. The problem with this is that if I use a good username and password it works but if I put in a bad username and password it doesnt do either one of them. Any ideas on how to just count the number of results?
There are 3 textboxes->textbox1,textbox2,textbox3 and 1 button.In textbox1 bname will be stored and in textbox2 aname is stored.Bname and aname are columns of databasetable.This are not unique.There are same bnames and anames records.What I am trying to do is:when the user clicks on button then the code should match textbox1 and textbox2 with the databasetable and get the count of rows that match this data. And print the count in the textbox3.If there is no similar bname and aname in the table then the count should show 0.I tried doing this but am pretty sure that its not right as its not working.

I'm using VB.NET, and I'm trying to write a program for the company I work for, that interacts with a database designed for logging web site email submissions (After a user fills out a form for a item request or comment sheet, the email the form sends gets logged so we can more easily see which site gets spammed more, and we keep a record of the actual spam). My program mainly just makes the data easier to read. However, I want to add a feature so that a user can click a button, then an automatic query will take place so that all the preserved URLs in the database are tested, then a form will appear that states something along the lines of: These Sites Sent This Number of Emails
