I have a text control in an ASP page in which user can enter alphanumeric data.I want to change lower case letters to uppercase once user enters a character and i am doing that using onkeypress event and it works fine but,the problem is suppose i have a value like CD-1-02-4010 in the text box and i think that i have entered wrong value and try to change any character in the value it is appending at the end of the value.It is not being entered in the right place.How do i overcome this

Here how i have
<form id = "frm">
<input type = text id = "txtTest" onkeypress = "Vbscript:CaseConversion"></input>
</form>
<script language = "vbscript">
    sub CaseConversion
      frm.txtTest.value = ucase(frm.txttest.value)        
    end sub
</script>

Above Code works but,it doesn't let me change the value.Some one please help.Thanks

Your problem is then when a key is pressed your function is executed, it substitutes the value of a input box and then returns after which the character gets in the box.

try using this

<form id = "frm">
<input type = text id = "txtTest" onkeypress = "Vbscript:CaseConversion"></input>
</form>
<script language = "vbscript">
   sub CaseConversion
     if window.event.keyCode >= 97 and window.event.keyCode <= 122 then
          window.event.keyCode = window.event.keyCode - 32
       end if
   end sub
</script>

if a user types any character from lowercase 'a' to 'z' it will be substituted by uppercase 'A' - 'Z'

On my computer it runs just fine, what do you mean by the first character. The first one you typed or the character 'a'?

Try this

<form id = "frm">
<input type = text id = "txtTest" onkeypress = "Vbscript:CaseConversion"></input>
</form>
<script language = "vbscript">
  sub CaseConversion
    if window.event.keyCode > 96 and window.event.keyCode < 123 then
         window.event.keyCode = cint(window.event.keyCode) - 32
      end if
  end sub
</script>
