Question about VB

scojones

Ok i'm doing user and password authentication by simply comparing two strings. The way it was thought in a lecture was silly. password=InputBox("enter your pw") stuff like that. What i'm wondering is with InputBox can you hash out (*) what the user enters in the password field so that users behind you cannot see what you type. I know there is a property to do this for a txtbox, i'm just wondering about an inputbox.. cheerrs

Don't think there's a property.

You could try deleting each char as it's input, and writing out a *, bit of a hack though, and won't work when it's a slow machine.

that'd be too much work for a little thing like that. Thanks for the help though much appreciated

amen

You cannot do it with the basic InputBox, because once the inputbox dialog appears, you have no programmatic control until the user returns from it via OK or Cancel.

The standard approach is to write a simple Login Box form, with all the necessary handling.

If you want to make it reuseable, then you dont get the form to do anything except accept the input values, and then make them available as properties of the form, as well as info on whether the OK or Cancel buttons were pressed (yes, you can add properties to the form, and even reference them after the form has unloaded without forcing the form to reload).

Then, get your Sub Main (or whatever) to essentially have code like :

bContinue = false
bExit = false
while not bContinue and not bExit
    frmLogin.Show vbModal
    if not frmLogin.CancelPressed then
      sUsername = frmLogin.Username
      sPassword = frmLogin.Password
      bContinue = MyLoginFunction(sUsername, sPassword)
    else
      bExit = true
    end if
end while      

if bExit then
    'code to exit application here?
end if

At least, thats how I'd do it
