The code you posted checks txtAccount name in both subroutines, ignoring txtIssuingBank. Apart from that, this code looks ok to me.

VB Code:
  1. Private Sub txtAccountName_Validating(ByVal sender As Object, _
  2. ByVal e As System.ComponentModel.CancelEventArgs) Handles _
  3. txtAccountName.Validating
  4.  
  5. If IsNumeric(txtAccountName.Text) Then
  6. ErrorProvider1.SetError(txtAccountName, "Not a numeric value.")
  7. Else
  8. ' Clear the error.
  9. ErrorProvider1.SetError(txtAccountName, "")
  10. End If
  11.  
  12.  
  13. End Sub
  14.  
  15. Private Sub txtIssuingBank_Validating(ByVal sender As Object, _
  16. ByVal e As System.ComponentModel.CancelEventArgs) Handles _
  17. txtIssuingBank.Validating
  18.  
  19. If IsNumeric([b]txtAccountName.Text[/b]) Then
  20. ErrorProvider1.SetError(txtIssuingBank, "Not a numeric value.")
  21. Else
  22. ' Clear the error.
  23. ErrorProvider1.SetError(txtIssuingBank, "")
  24. End If
