How to identify between ok and cancel button in inputbox

Question

Hi Hi I have to write a code where if the user clicks enters something in the input box it should proceed further.If it doesnot enter any value it should throw back the same

Answer 1

I'm using VBS and my investigation into cancel/ok revealed the following:

Cancel returns an empty string AND a zero length string - same thing you say?, apparently not.

Ok returns a zero length string only.

I use the code below to differentiate.

   if IsEmpty(nmbr)  then               'cancel button pressed ?
        nmbr = "x"  
   end if  

   if not IsEmpty(nmbr) then            'ok button pressed ?
      if len(nmbr) = 0 then
        nmbr = "ok"
      end if 
   end if
