Hide Password in Input Box

[smtazulislam]

Thank you so much. Its work..

 

[isladogs]

Glad to have assisted.
As already stated, I do urge you to ENCRYPT your passwords

As already stated, I do urge you to ENCRYPT your passwords

No sir, I have a strongly login password. and 5 users use with secure. But I here show shortly demo .
I have another question.
If I would like to input my own create a FORM then what I should change there ?

 

[isladogs]

You are missing the point.
No matter how strong the passwords are, storing them in an Access table with or without a password mask is totally insecure.
It is trivial for any user to remove the table password mask and, by doing so, be able to view all users passwords.

If you must store user passwords, encryption is absolutely essential to provide some degree of security.
Better still, don't store passwords. Use Active Directory instead. That is VERY secure.

As for your other question, you are hijacking the thread by asking your own unrelated question.
Please start a new thread for that question. I suggest you also try and explain it more clearly

That's a functional code I used to use on 64bit

I have made some enhancements to post #27 by @riti90

• The function is named InputBox() and will override any normal calls to the VBA InputBox thus you don't have to update code if you implement in an existing app.
• It has an additional parameter that when set to True will mask all input as '*'
• If a Title is not passed it will default to the app title.
• As a bonus this also includes a MsgBox function that will override the VBA MsgBox function and default the dialog title to the app title if one is not passed.
• I recommend you save this code in a new module named basInputBox. The beauty of this code is that you can add it to any existing app and it should not break existing code. It does not rely on any forms or references.

Thanks Ben
I will look at your code properly, hopefully in the next few days

 

[Mylton]

What does that mean exactly? What does happen?
Did you copy the entire code needed for InputBoxDK?

Have a look at the code on my website Masked Input Box - Mendip Data Systems

EDIT: You have a syntax error in the DLookup line. It should be as shown below with no quote mark before Password:

If x<>DLookup("*", "Users", "UserName = '" & me.txtUserName & "' And Password = '" & x & "'")

good night
Could you please update the example address?
thanks.

good night

thanks.

As requested, I've just updated two old links in this thread

Hello to all! and thanks!!
I am not very skilled on VBA. I do have a Type mismatch error on on this statement:
hHook = SetWindowsHookEx(WH_CBT, AddressOf NewProc, lngModHwnd, lngThreadID)
error is over lngThreadID parameter. Any comment will be apreciated!!

Are you using the code from my website or that by @bsacheri in post #49?

You'll need to help us help you as I can't replicate the issue
Which version/bitness of Access are you using?

 

[Pat Hartman]

Maybe I'm missing something but that seems to be a lot of code for nothing.

If you create a tiny popup form with a textbox, you can set the input mask to "password" to hide the text as it is typed. The popup form would place the entered value into a control on the calling form and then exit. The control on the calling form can be hidden or if visible, use the "password" input mask to hide the text.

Hello!
Thanks for your answer.
and yes I am testing @bsacheri code. I am using Access for Microsoft 365, my references are:

Visual Basic For Applications
Microsoft Access 16.0 Object Library
OLE Automation
Microsoft Office 16.0 Access database engine Object Library

let me know if something else is needed.

 

[isladogs]

I've already tested it without error in A365 version 2301 and with the same standard references

32-bit or 64- bit? Version and build number for A365? You might find it easier to use my version checker utility for this

Access/Office365/Win Check

Use this utility to obtain the full Access/Windows/Office 365 version and bitness information

www.isladogs.co.uk

It is also available as an add-in.

Also suggest you test the older masked input box code on my website and see if that works for you

Masked Input Box

This article contains an updated version of the masked input box code and works in 32-bit and 64-bit Access

www.isladogs.co.uk

 

[isladogs]

UPDATE
Just tested it in 64-bit Access & got the same error
Easily fixed.
Change the following line from

Dim lngModHwnd As LongPtr, lngThreadID As LongPtr

to

Dim lngModHwnd As LongPtr, lngThreadID As Long

so that it matches the output of the API declaration for GetCurrentThreadId

Tested & working in both 32-bit & 64-bit

 

[bejaranoangel]

Hello Sir!!
Workeeed!!
I though for x64 ptr was the correct. Thanks so much!, and I wanna get this chance that I grab your attention to let you know that I been follow your job per years, every time I see your contributions are just admirable and personally help full. You're one of the greatest on this area. I wish you the best @isladogs.
Best Regards.
PD: Greetings from México. Apologize my English

 

[isladogs]

Thanks for your very positive feedback

For info LongPtr is only needed for handles & pointers such as hWnd (or in this case lngModHwnd)
Whereas lngThreadID isn't being used as a handle, Long is correct

There are many lengthy articles about this topic, some better than others. For a good example, see:

For info, standard input boxes cannot handle languages which use unicode characters sets e.g. Arabic, Japanese, Malayalam without changes to locale and keyboard settings. This is also true for standard message boxes

However, I've just posted a web article which includes a new function UnicodeInputBox which does work with Unicode characters sets including right-to-left languages such as Arabic, & Hebrew

Unicode Input Box

This function allows input boxes to handle unicode character sets used in languages such as Bengali, Chinese etc without changes to locale or keyboard settings. It can also handle right-to-left languages such as Arabic and Hebrew. A further advantage is that it can be used successfully with...

www.isladogs.co.uk

For example

The language used for the buttons is automatically updated when the Office language is changed

I've not included the code that Ben Sacherich posted earlier but I may merge both sets of code at a later date

Maybe I'm missing something but that seems to be a lot of code for nothing.

If you create a tiny popup form with a textbox, you can set the input mask to "password" to hide the text as it is typed. The popup form would place the entered value into a control on the calling form and then exit. The control on the calling form can be hidden or if visible, use the "password" input mask to hide the text.

I like this approach because it is easy to implement into an existing application. All you need to do is add one code module. All of your existing code will continue to work. Any place you want to accept password input you can pass an additional parameter to the InputBox() function. The dialog that appears will still have the standard look and feel of other dialogs.

In other applications I have created a custom InputBox form but for my most recent app I felt that copying a form and a module and then tweaking the looks of the form was more work than I wanted to deal with. I guess it depends on the situation.

 

[Pat Hartman]

Not sure why you prefer code to a property setting but whatever.
