Password Field

[Jerry Daniels]

Brian,

I answered this last week for Doug Lerner but maybe my email went 
astray or maybe you didn't see it. Here follows an answer to your 
question (as well as his)...

************************

Here's one possible way to tackle your question number 2 (password 
entry so that you only see asterisks):

1. Make two editable (but empty) text fields called "password" and 
"password mask."
2. Hide "password" but keep "password mask" visible for text entry of 
the password.
3. Put these handlers into the visible field, "password mask":

on keyDown theKey
   --> FIND OUT WHAT'S SELECTED:
   put the selectedChunk into theChunk
   put word 2 of theChunk into theStartPos
   put word 4 of theChunk into theEndPos
   --> PUT ASTERISK INTO THE SELECTION IN VISIBLE MASK FIELD:
   put "*" into char theStartPos to theEndPos of fld "Password Mask"
   --> PUT REAL DATA INTO THE HIDDEN FIELD:
   put theKey into char theStartPos to theEndPos of fld "Password"
   focus on me
end keyDown

on keyUp
   --> GET THAT SELECTION GOING AGAIN:
   focus on me
   pass keyUp
end keyUp

on backspaceKey
   --> IF THEY HIT BACKSPACE...SAME IDEA AS KEYDOWN:
   put the selectedChunk into theChunk
   put word 2 of theChunk into theStartPos
   put word 4 of theChunk into theEndPos
   if theStartPos > theEndPos then
     put empty into char theEndPos of fld "Password Mask"
     put empty into char theEndPos of fld "Password"
   else
     put empty into char theStartPos to theEndPos of fld "Password Mask"
     put empty into char theStartPos to theEndPos of fld "Password"
   end if
   focus on me
end backspaceKey

on deleteKey
   --> IF THEY HIT DELETE...SAME IDEA AS KEYDOWN:
   put the selectedChunk into theChunk
   put word 2 of theChunk into theStartPos
   put word 4 of theChunk into theEndPos
   if theStartPos > theEndPos then
     put empty into char theStartPos of fld "Password Mask"
     put empty into char theStartPos of fld "Password"
   else
     put empty into char theStartPos to theEndPos of fld "Password Mask"
     put empty into char theStartPos to theEndPos of fld "Password"
   end if
   focus on me
end deleteKey

When you want the password, it will be in the hidden field "password", 
not "password mask."

Hope that helps,

Jerry Daniels
