    <p>I'm trying to get a script that works both in a native windows shell and a cygwin shell (via ssh) that prompts for and reads a password entered by the user. So far, I have tried the following methods:</p> <ol> <li>using Term::ReadKey and setting ReadMode to 'noecho' <ul> <li>RESULT: returns an error <code>GetConsoleMode failed</code> and quits</li> </ul></li> <li>using Term::ReadPassword::Win32 <ul> <li>RESULT: hangs and never offers a prompt or reads input</li> </ul></li> <li>using IO::Prompt <ul> <li>RESULT: returns an error <code>Cannot write to terminal</code> and quits</li> </ul></li> <li>using Term::InKey <ul> <li>RESULT: returns an error <code>Not implemented on MSWin32: The handle is invalid</code> and quits</li> </ul></li> </ol> <p>All of these work in a native Windows shell (command prompt or power shell), but none of them work when I'm in an ssh session to the server.</p> <p>Really, that's what I'm most interested in, getting it to work in the remote ssh session.</p> <p>I'm getting ssh via cygwin installed on the Windows server (2003 R2). I'm using strawberry perl and not the cygwin perl (cygwin perl breaks other perl scripts I need to run natively in Windows, not via ssh).</p> <p>My best guess is that cygwin+Windows is screwing with strawberry perl enough that it can't tell what kind of environment it is in. I'm looking into alternative sshd+Windows solutions to explore this.</p> <p>These are all the methods I've been able to find in my searching. Does anybody else have any other methods for hiding user input they can suggest?</p>

    1. COWhat do you mean 'none of them work'? Does the user not get a prompt or is the user's input not hidden?

    3. COTesting from ssh session, the first method returns an error `GetConsoleMode failed` and quits, the second method hangs and never offers a prompt or reads input, the third method returns an error `Cannot write to terminal` and quits, and the fourth method returns an error `Not implemented on MSWin32: The handle is invalid` and quits. In a native Windows shell they all work except for the third method which returns the same error, so it's possible I'm just not invoking it correctly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
