Masked TEdit derived control to get password input

[Gianni Rossi]

Hello,

I have a Borland C++ 5.02 OWL application (so not OWLNext) in which I need to request the user password and obviously I would like to implement a usual masked input visualizing dots instead of the real typed characters.

So I wonder if someone of you has already implemented a TEdit derived class for this purpose and is willing to send it to me.

Thanks in advance.

Hi Gianni:

The standard windows EDIT control (aka TEdit for OWL/OWLnext) already has the 'password' attribute. Just use the Resource Workshop to enable the 'password' atribute.

Best regards,
Sebastian

Hi Sebastian,

Thanks for your reply.

Sorry I did not well specify my purpose.

I would like to show dots instead of asterisks and also allow only a certain
set of characters.

Ciao,

Gianni Rossi

1 - I dont know of any implementation of 'TPasswordEdit' that allows to select the visible char.
2 - You can use a TValidator to allow specific chars. in your TEdit.

Hi, Gianni,

You can try to use TEdit::SetPasswordChar() to change the displayed character in a password edit box. Behind the scenes it sends a EM_SETPASSWORDCHAR message to the control.
