Email validation and javascript

Email validation and javascript

• ERK

  Hi,
  I think you are talking about ASP.Net Project using Vb.net.
  If so then...
  
  Solution 1
  Tto validate email address for a textbox put a expression validator set its ControlToValidate property to text box for which validation is required and from its ValidationExpression select Internet Email Address.
  
  Solution 2
  If you want to show javascript confirm message on server sided button control click event then write following code at page load...
  
  

  btnDelete.Attributes.Add("onclick", "return Del();");
  
  Now what you have to do is declare a javascript button in HTML of you page.
  
  <script language="javascript">
  

  function Del()

  {
  
  if (confirm("Are you sure to want to delete "))
  
  { return true; }
  
  else
  { return false; }
  
  }

  </script>

  Hope this help.

  thanks Mubshir Raza Ali

  the javascript problem i solved it by using other method already......but how can i check the email input by the user whether it is in valid type......txtEmail.Text <> "\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*

  but this is not a correct way to do it........(this is what i did in vb.net).... but now i wanna check it in visual basic....is there any possible way to check it

  thanks

  is it possible for us to add a javascript in visual basic project.......

  Not in VBE.

  The paid for products have the Visual Web Designer built in so you can do web projects including javascript. You can still do a web project by down loading Visual Web developer. I believe that's still free.

  thanks for ur help, Mubshir Raza Ali

  i found another solution which is easier to use.....below is the sample solution for email validation

  Regex.IsMatch(txtEmail.Text, _
  "^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\] )$") = False Then

  epModifyMerchant.SetError(txtEmail, "Invalid email type")

  thanks

  Hi,

  Ok here is email validation in VB6

  Public Function IsEmail(argEmail As String) As Boolean
  Dim tabemail() As String
  Dim tabprovider() As String
  
  IsEmail = False
  
  If InStr(1, argEmail, " ", vbTextCompare) = 0 Then
  tabemail = Split(argEmail, "@")
  If UBound(tabemail) = 1 Then
  tabprovider = Split(tabemail(1), ".")
  If UBound(tabprovider) > 0 Then
  If Len(tabprovider(UBound(tabprovider))) >= 2 Then IsEmail = True
  End If
  End If
  End If
  End Function

  You can find details here!
  
  Hope this help
