You could always do this by sub-classing the edit control. (You would
trap WM_CHAR messages, save the characters in your own buffer, and pass
an asterisk, space or other character to the original wndproc.)

Windows 3 has a new edit control style, ES_PASSWORD, that makes this all
very easy. By default an asterisk will be displayed, rather than the 
character typed. You can change the character displayed by sending the
control the EM_SETPASSWORDCHAR message.

As noted in a previous posting, a similar mechanism is provided in 
OS/2 1.2.
