Show message box in vb.net

This is just sample messagebox code using vb.net language. I place this in the onclick button and prompt it during save. the code looks like this one.


Dim rstResult As DialogResult

rstResult = MessageBox.Show("Are you sure want to update?", _
"Business Card", _
MessageBoxButtons.YesNo, _
MessageBoxIcon.Question)

If rstResult = DialogResult.Yes Then
// do some action here. is the user selected Yes and nothing is no.
End If
