Tonyckx-

Are you trying to detect wether the user pressed all of these keys at once?  Or in a series with each other?

If it is in a series, simply write code in the change event that interrogates the value of the textbox.

i.e.

private function textbox1_change()
   dim required(4) as integer
   dim x as long
   for x = 1 to len(textbox1.text)
      if mid(textbox1.text,x,1) = specchar then
         required(1) = 1
      else
         if mid(textbox1.text,x,1) = captial then
            required(2) = 1
         else
            if mid(textbox1.text,x,1) = lower then
               required(3) = 1
            else
               if mid(textbox1.text,x,1) = number then
                  required(4) = 1
               end if
            end if
         end if
      end if
   next

   If all required's are 1 then
      success
   else
      fail
   end if


P.s.  You would check for number, special char, etc...by using the ASC function against each character to get the ASCII value

sadcock,
i use a textbox to give user key in  string of character.  when user click command button, a algorithm will check the input textbox. so how i want to write a algorithm to check the input are combination of Capital letter, small letter, number and speacial character? example if the input is:-
1)abcde (boolean = false because small letter only.)
2)1234  (boolean = false because number only)
3)!@#$  (boolean = false because special character only)
4)abc!@#123 (boolean = false because no capital letter)
5)!@#TonyCKX123 (boolean = true) combination of Capital letter, small letter, number and speacial character

can you give me some coding about the situation? thanks very much.
