Hello,

How do I create a password entry dialog box, i.e. a dialog box that replaces the password with dots?

Thanks

Use a string control with the display mode set to "Password"

By using a String control instead?

I haven't been working with labview that long.

How do you make a string control into a dialog box that allows someone to inconspicuously enter their password?

Place a String Control on your Front Panel.

Right-click said string control.

Look at the options until you see "Password Display"

Click that.

Type into string control and see the pretty ******s

You'll want to get used to right-clicking to see what options you have available. Otherwise, you'll spend more time waiting for answers than you will actually developing. Don't be scared of the code. Odds are, you can't hurt it.

1. Place the Express VI 'Prompt User For Input' onto a BD

2. Configure the inputs as you want, ie. two text inputs 'User' and 'Password' and an OK and Cancel button.

3. Click OK to finish configuration

4. Right-click the Express VI and choose 'Show Front Panel'. Confirm that you want to convert to a SubVI

5. Right-click the password string control and set the display to 'password'

6. (optional) right-click the Express VI again on the diagram and choose 'View as Icon'

Now you have a subVI which will serve as a password dialog box.

I already noticed that and i was able to get the string control to work for password entry.

However, I want the user to enter the password into a dialog box.

How do I create the dialog box that has a string control in it?

If you want the password entry screen to have a certain appearance, you'll need to make your own VI with a string control & buttons and use this as the password checker. With most cases, if you aren't happy about the default appearance, make your own.

This can be implimented in a number of ways, such as a subvi within your main program which stays in a while loop until the correct password is provided OR the user hits cancel (close LabVIEW on cancel). The other way is to have the password checker as a stand-alone VI and launch the main VI via a reference call after the correct password is provided.

That's what I was looking for. Sorry about the two duplicate post.
