Simply drag the “magnifying glass” over any “password” edit control and Eureka!

Eureka! is a 32-bit Windows utility that allows you to view password fields. For
example, let’s say that you forget what your FTP password is. If you use WSFTP,
the security dialog shows you the password in an Edit field. However, it is shown
as a row of asterisks. This is because the ES_PASSWORD style was used for Edit
control. Using Eureka! you can uncover that lost password! Simply click on the
magnifying glass icon and drag it over the password edit control and Eureka!,
the text “behind” the asterisk will appear on Eureka!’s dialog!

This application was developed using Visual C++ 5.0 and has been tested on both
Windows ’95 and Windows NT 4.0 Workstation. The source code for this application is
freely downloadable. It should be understood that this application was NOT developed
for the purpose of any illegal activity. This application should only be used for
the purpose(s) expressed. Insofar as the source code is concerned, you are free
to download this code. The only thing I ask is that you do not claim my work as
your own own. In other words, give credit where credit is due.


  • While this utility has been tested and does work with the password screens
    of such applications as WSFTP, CuteFTP and Outlook Express, it does not work with
    Internet Mail and the Windows NT User Manager. Why not? Who knows 🙂 I wrote this
    app in about an hour for a specific purpose and have never had the time to go back
    and make it work with all applications. If anyone wants to “fix” this, I’ll be more
    than happy to update the code and give them credit.

Version History

  • August 3, 1999 – Original version
  • February 11, 2000 – Original version was hardcoded to look for windows that were defined
    with a class name of “Edit”. Steve Bryndin
    updated the source code to provide the ability to enter a list of Windows classes on
    the dialog that are treated as password edit controls.
