Basically I'm retrieving all the data in my program through runtime, I was wondering how will I retrieve the number of rows affected after an update so I could prompt the user about it through VB.NET

How do I get it where when I click button2, it will count the number of rows in the mysql table and then display it in a messagebox or label1.text?
The user has to enter the text in the textbox , to write a text user need to press the keys and release the keys. Write a code to count the number of keypresses and keyreleases and display the value in the labels.
View 1 Repliesi have a Dataset command (DELETE FROM TABLE Where Name =@name)On my winform i have a Delete button that it deletes the rows, next i want to display the number of rows deleted to a msgbox, what i get now is 0this is my code:
Me.NetworkErrorsTableAdapter.Del(par)
MsgBox(" " & Me.NetworkErrorsTableAdapter.Del(par).ToString & " records deleted ")
Any method that can effectively get the total number of rows that is StartRows to EndRows in a database table and then get the corresponding data from that row as currently I am having difficulty in retrieving out the correct row of data to the column that I am comparing. It will always get the first row of data regardless of which row I put in the handphone number which I'm comparing to. The codes below is the one which I am currently using now to detect the maxrows in the database and also to retrieve the corresponding information.
MaxRows = ds2.Tables("CustDetail").Rows.Count
MaxRows = MaxRows - 1
Dim numbers() As Integer
Dim EndAt As Integer
inc = 0
[Code] .....
I used a msgbox(n) to see the number of rows in the database but it displays only one where I have two rows in my database. The for loop is the one which will detect the number of maxrows and also retrieve out the corresponding details. But apparently this is not the appropriate way.

I am trying to run a nested loop; it should call a result from a MDB database. Which it does, when I run the single loop it goes thru all of the entries. But when I try to get a number to display twice it stops on the second entry. Having it display the number twice is just a test to make sure it does work, I am going to modify it after I can prove the loop works. The count on the Message Box is correct, but the number displayed is wrong?I want it to display each number twice and then move on to the next number. [code]
View 2 Repliesdesigning a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"
