Replace password with *** in input box, xlVeryHidden

[John]

Hi,
The following code works fine but the password "secret" is visible as I
type. How can I hide it? Can I hide it by putting a label or another box on
top of the password input box? I believe it is not possible to hide charters
inside an input box...

Private Sub CommandButton1_Click()
pwd = "secret"
i_pwd = InputBox("Please Enter Password to Unhide Sheet", "Unhide Sheet")
Select Case i_pwd
Case pwd
Worksheets("Sheet1").Visible = True
Worksheets("Sheet2").Visible = True
Worksheets("Sheet2").Activate
Case Else
MsgBox "Incorrect password; no action taken.", vbInformation, "Unhide
Sheet..."
End Select
End Sub

this site should point you in right direction:

Yep. You can not do this kind of thing with an inputbox.

But you could design your own form. There's a .passwordchar property for
textboxes that you could change to asterisk.

Thank you Dave.

Do you mean: Make a a new Custom UserForm in VBA, and then insert a textbox
from the tools menue. Then set the property of this inserted textbox to xxx?
Or do I develop a form in "Excel mode". (I'm not an expert of VBA yet...)

If you want to design your own userform:

You can change properties within the VBE (manually) or you could use code:

Option Explicit
Private Sub UserForm_Initialize()
Me.TextBox1.PasswordChar = "*"
End Sub

Here is the end result for the un-hide operation:

'In the sheet where I have the button to call the UserForm:
Private Sub CommandButton1_Click()
Password.Show
End Sub

'The UserForm Cancel button:
Private Sub CancelButton_Click()
Unload Me
End Sub

'The UserForm OK button:
Private Sub OKButton_Click()
If TextBox1.Text <> "secret" Then
MsgBox "Invalid Password"
Exit Sub
ElseIf TextBox1.Text = "secret" Then
Worksheets("Sheet2").Visible = True
Worksheets("Sheet1").Visible = True
Worksheets("Sheet1").Activate
Unload Password
End If
End Sub

The UserForm has a TextBox with TextBoxCharter set to "*", and the form is
called "Password"

Make sure you protect your project, too.

Inside the VBE:
Tools|VBAProject Properties|Protection tab

It's not 100%, but will keep most people from viewing your code.

=================================================
Sub CommandButton1_Click()
pwd = "secret"
i_pwd = InputBox("Please Enter Password to Unhide Sheet", "Unhide
Sheet", , 10000, 9500)
'
' nobody can see the text that you type because it is out of screen !!!

Select Case i_pwd

what is your question?

so this is not a question. You are saying that instead of using a textbox
control with the password character set, one can use an input box and place
it off screen somewhere? I use Vista and I see the input box - it will not
allow a user interface where a user cannot enter it. I'd suggest this is not
a good idea.

Thanks the code works exalctly the way i wanted

There is another solution which avoids using a textbox on a userform.
First, though, credit to Daniel Klann (there used to be a link to this
but it doesn't work anymore:
'DanielKlann.com | Daniel Klann'
(http://www.danielklann.com/excel/hiding_text_in_a_vba_inputbox.htm)
but there's another one 'here '
(http://www.tek-tips.com/faqs.cfm?fid=4617)and I include the code
below.

I would put the entire code below into its own code module then forget
it:

Code:
--------------------
Option Explicit
'////////////////////////////////////////////////////////////////////
'Password masked inputbox
'Allows you to hide characters entered in a VBA Inputbox.
'
'Code written by Daniel Klann
'March 2003
'////////////////////////////////////////////////////////////////////
'API functions to be used

'Constants to be used in our API functions
Private Const EM_SETPASSWORDCHAR = &HCC
Private Const WH_CBT = 5
Private Const HCBT_ACTIVATE = 5
Private Const HC_ACTION = 0
Private hHook As Long
Public Function NewProc(ByVal lngCode As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Dim RetVal
Dim strClassName As String, lngBuffer As Long
If lngCode < HC_ACTION Then
NewProc = CallNextHookEx(hHook, lngCode, wParam, lParam)
Exit Function
End If
strClassName = String$(256, " ")
lngBuffer = 255
If lngCode = HCBT_ACTIVATE Then 'A window has been activated
RetVal = GetClassName(wParam, strClassName, lngBuffer)
If Left$(strClassName, RetVal) = "#32770" Then 'Class name of the Inputbox
'This changes the edit control so that it display the password character *.
'You can change the Asc("*") as you please.
SendDlgItemMessage wParam, &H1324, EM_SETPASSWORDCHAR, Asc("*"), &H0
End If
End If
'This line will ensure that any other hooks that may be in place are
'called correctly.
CallNextHookEx hHook, lngCode, wParam, lParam
End Function

Public Function InputBoxDK(Prompt, Optional Title, Optional Default, Optional XPos, _
Optional YPos, Optional HelpFile, Optional Context) As String
Dim lngModHwnd As Long, lngThreadID As Long
lngThreadID = GetCurrentThreadId
lngModHwnd = GetModuleHandle(vbNullString)
hHook = SetWindowsHookEx(WH_CBT, AddressOf NewProc, lngModHwnd, lngThreadID)
InputBoxDK = InputBox(Prompt, Title, Default, XPos, YPos, HelpFile, Context)
UnhookWindowsHookEx hHook
End Function

--------------------


Now you can replace your line:

Code:
--------------------
i_pwd = InputBox("Please Enter Password to Unhide Sheet", "Unhide Sheet", , 10000, 9500)
--------------------

with:

Code:
--------------------
i_pwd = InputBoxDK("Please Enter Password to Unhide Sheet", "Unhide Sheet")
--------------------

Worked here in xl2003.

so this is not a question. You are saying that instead of using a
textbox
control with the password character set, one can use an input box and
place
it off screen somewhere? I use Vista and I see the input box - it will
not
allow a user interface where a user cannot enter it. I'd suggest this
is not
a good idea.
