Hi all,

When I was connecting to the Internet I came up with the idea to make a password/login program just like Windows XP has. For the people who doesn't have XP: you can save your password, but nobody can read it, cause there is an other textbox over it which is showing 'Click to change the password'. So even with programs like Password Spy you can not get them...

Code:

%%username = username
%%password = password
  DIALOG CREATE,Password,-1,0,185,82
  DIALOG ADD,EDIT,eUsername,8,4,180,19,%%username
  DIALOG ADD,EDIT,ePassword1,32,4,180,19,,,PASSWORD
  DIALOG ADD,EDIT,ePassword2,32,4,180,19,Click here to change your password
  DIALOG ADD,BUTTON,bLogin,54,4,64,24,Login
  DIALOG SHOW

:Evloop
wait event,"0,1"
%%event = @event()
goto %%event

:Timer
if @equal(@focus(),ePassword2)
  dialog remove,ePassword2
  dialog focus,ePassword1
  end
goto evloop

:bLoginBUTTON
if @both(@equal(@dlgtext(eUsername),%%username,EXACT),@equal(@dlgtext(ePassword1),%%password,EXACT))@winexists(~ePassword2)
  info Hello %%username.@cr()You've been logged in correctly.
  else
  warn Oops... Try it again...
  end
goto evloop

:Close
exit

The password still could easily be retrieved using the Window Spy of VDS.

Also this call is invalid: @winexists(~ePassword2)

Randomly it will throw an access violation because you could only use the ~ "operator" for
valid existing controls, it won't work for non-existing controls.

Oops... I forgot that I've put the right password in Password1... My fault.

But about that @winexists(ePassword2), what is wrong with that? If there isn't a valid control, it will set @ok() to false, so it will work...

After entering some text in the password box and clicking "Login" it will crash with
Exception: Access violation at address 004201AF. Read of address 000000C0
because of the problem that I mentioned. This happens with VDS 4, I'm not sure if
it applies to VDS 3 as well.

The script doesn't work in VDS 3, because it usses the @focus() function.
