Hi all,
Workbook Demo.
As the tilte says, this is just a standard vba inputbox that I have customized with the use of the Windows API in order to validate user input dynamically as you type-in as well as masking the input with a password character (*) if required.
Another cool functionality I added to the function is the ability to show a balloon tooltip to inform the user when an event is fired.
The InputBoxEx function has the following signature:
Function InputBoxEx( _
ByVal Prompt As String, _
Optional ByVal Title As String, _
Optional ByVal Default As String, _
Optional ByVal XPos As Variant, _
Optional ByVal YPos As Variant, _
Optional ByVal HelpFile As String, _
Optional ByVal Context As Long, _
Optional ByVal OnKeyEventProcedure As String, _
Optional ByVal PassWordCharacters As Boolean, _
Optional ByVal AllowNumbersOnly As Boolean, _
Optional ByVal MaxChars As Long, _
Optional ByVal ShowBalloon As Boolean, _
Optional ByVal BalloonIconType As ICON_TYPE, _
Optional ByVal BalloonTitle As String, _
Optional ByVal BalloonText As String _
) As String
Among the arguments, there is this interesting OnKeyEventProcedure parameter which takes the name of the event callback routine whose signature is in line with the standard Office events layout (See the Test4 example routine below)
The callback routine is passed two arguments : (1) Byval the ASCII code of the character being typed-in and (2) ByRef a Cancel argument to stop the character from being entered into the InputBox.
1- Code in a Standard Module:
2- Code Usage examples:
I 've only tested the code on Excel 2016 64bit Windows 64bit and Excel 2007 Windows 64bit/32bit and I haven't notice any issues.
