filtering user input

[tamir]

how can i prevent a user from entering specific characters such as ! ^ & into an input control?

or maybe just allow the user to input letters (and maybe integers too)

i think there is a more proper way but my solution would be to check for those characters in the while loop and if they show up automaticly delete them and play the error noise. some one else probably has a better solution though

I would do it this way, myself.

Check for the existance of illegal characters with a StringSplit, For, StringIsXXX, Set Flag, Next loop.

Dim $input, $inputarray, $flag = 0
Do
   $input = InputBox("Test","Put test text here")
       If @error = -1 then Exit
   $inputarray = $input
   StringSplit($inputarray,""); splits each element into an array.

   For $x = 1 to $inputarray[0] step 1
      If StringIsAlpha($inputarray[$x]) = 0 or _ 
          StringIsDigit($inputarray[$x]) = 0 then $flag = 1
   Next
   If $flag = 1 then MsgBox(48,"Error","Illegal Characters Specified." & _
       @LF & "Please use only letters and numbers.",5)
Until $flag = 0

Hi,

Try using the _IsPressed function inside an AdLibEnable ?
