i 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 ")
how do i count the number of rows that are affected when I updated a table, and display the number of affected rows in a message box ??
here is my code for updating the table ...
For Each row As DataGridViewRow In DataGridView1.Rows
req = row.Cells(Column1.Name).Value
If row.Cells("Column1").Value = True Then

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 have two datatable that I pull information from a db. I have a complicated form, and I have found it easier to write a simple SQL statement to pull the records. I have then used other controls on the form to trim the info down even further. When a particular falls out of the secondary control it is then deleted from the datatable.
I am then going back through the datatable and performing other actions on the datatable. When I narrow the information, sometimes I'm getting a DeletedRow is inaccessible. I have been looking at a way to do an IF statement to see if a row has been deleted, but I haven't figured out a way to skip a deleted row. Is there a way to skip a deleted row that I'm not seeing.
The problem im having is that I have a table that when a user click on a button it adds a row to the table via javascript, which works fine. The problem is that if a user need to update other data the user click another button which refreshes the page and all rows the user created in the table are deleted. My question is what can I do to make the rows not to be deleted once the page is refreshed? I know some might think, just not refresh the page, but there is to much data that has to be displayed and a new query has to be generated to grab the data.

This code works fine for colllecting the the data and displaying it in the ListBox1. But then I want to display all the entries that are in the ListBox1 to a TextBox or MsgBox but I'm having trouble.
I'm stuck! i'm trying to read a txt file with the data as below:
LEE
JOSH
JOSH
[Code]....
the txt file is updating all the time. So, i like to read this file and then display in msgbox the name that is most duplicated. In this case the MsgBox will show JOSH.
So I want when you click Button1, it displays MsgBox ("Hello"), when you click again, it displays Msgbox("World"). Then it all starts Hello "world hello world" etc.

I'm currently having a form that has a button starting a long process, with feedback into another windows textbox (call frmProcessLog).
I'm using a Background worker to laucnh the process, upgrade the status of the process and display feedback on the frmProcessLog textbox, and to know when the thread process ended up, (from the cancel button, from an error or normal termination).
the main thread process has some msgbox in it, asking questions to the operator (yes/no/cancel).
I've added the msgboxstyle.systemmodal to the msgbox call which works "ok" excpet if the operator decide to ignore the showing message box and click the cancel button on the frmProcessLog form, which is still clickable even though I supplied "systemModal" to the msgbox. this makes the msgbox hidden behind the frmProcesslog form and the process can still continue.
If I close my frmProcessLog form, I will see the previously msgbox behind it and If I end up click one of the button it will end up at an application error because the thread that called it is not existing anymore.
So I would like that the msgbox to be launched from the thread making it as if it was launched from my frmProcessLog window in a modal way.
is there a way to generate a random number and then display that number?
like for example i want to say "i got # - # pencils" or something like that
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]
