Silent pw entry not working - Ra7eN - 12-11-2022

The following code does the following
prints "*" when entering a password (scratch built) and then return the plaintext back.

Instead it returns a zero and blank text. What did I miss? thanks.

Code: (Select All)
Print "-Enter Password: "; pInput$ = silentInput$

    Print pInput$ 'DEBUG DELETE AFTER TESTING

Code: (Select All)
Function silentInput$

    Dim Txt$

    Dim KeyPress$

    Txt$ = ""

    ' GREAT FOR PASSWORDS

    Do

        Do: KeyPress$ = InKey$: Loop Until KeyPress$ > ""

        If KeyPress$ <> Chr$(13) Then

            Txt$ = Txt$ + KeyPress$

            Print "*"; ' crate a visual

        End If

    Loop Until KeyPress$ = Chr$(13)

    Print

    silentInput$ = Txt$

End Function

PS, appreciate you guys keeping the qb64 going!! thank you

Adding a colon will fix it or a new line. Not sure why but it did!

Code: (Select All)
PRINT "-Enter Password: ";: pInput$ = silentInput$  

Code: (Select All)
PRINT "-Enter Password: ";

pInput$ = silentInput$

Good luck!

RE: Silent pw entry not working - Ra7eN - 12-11-2022

YES! that does work.
And I think I know why.

silentInput$ is a variable and I am still "printing" the var - it would seem to be similar to using

input "some text: ";a$

I think LOL

beuler, beuler??

Adding the colon is the same as separating the silentInput$ statement from the PRINT statement. So why does it need to be separated? Well, it's because that semi-colon ";" after the PRINT statement is telling PRINT you want to include IF pInput$ = silentInput$ to it. Like Ra7eN figured out, that's a variable comparison expression when it is used that way.

PRINT a = b' That would be false, so it returns zero.

PRINT "Pete" = "Steve" ' That would be false, so it returns zero.

PRINT "Pete" > "Steve" ' Well, that's a story for another time! Big Grin

So even though it still successfully calls the function, it isn't assigning the string variable pInput$ to the function return, it's comparing the null string pInput$ to the results of the the function. So it will always print "0" unless you just hit Enter without typing, which would return a -1, since a null string and an empty string are the same thing.

Welcome to the forums. You made Pete change away from his cowboy clothes into three-piece suit and back. Now let me see if I could remember that Looney Tunes episode... it must have been the "Wentworth" one ROFLMAO.

Wait, but not:

Code: (Select All)
PRINT "PETE" > "steve"

???

Well, apparently another time is here...

I've long said that's a bug in QB64...

First, let's change what you wrote to...

PRINT "pete" > "STEVE"

But wait, that dog won't hunt... "Expected variable required after =..." [Syntax error message].

So we have to go to the extra work and code...

a$ = "Pete"
b$ = "Steve"
PRINT a$ > b$
'output -1

Hey wait. TARNATION, that' still buggy!!! Big Grin

We do have fun around here. My excuse is I was too much Star Trek, and have a warped sense of humor.

I never understood the sense of a silent/hidden (or what ever you wanna call) input field.

Simply don't type your password if too many suspicious creatures hanging around you.

And..., if I would be one of those creatures, then I would follow your fingers on the keyboard, so you should better get a keyboard with blank keys instead.
