Prevent macro from Running Twice in one day (Using GetSetting and SaveSetting to hold values)

Hi one and all,
This time I have come up with a RunOrNot Macro.The purpose of this macro is to restrict user to run the Main Macro (YOUR_MACRO) for once in a day.

Changes required in the code:-
In the Code below you have to change the YOUR_MACRO with your actual main macro.The text of Msgbox can be changed accordingly.


Sub RunOrNot()
    ExDate = GetSetting("Excel", "Forum", "ExDate")
    
    If Not IsDate(ExDate) Then
        SaveSetting "Excel", "Forum", "ExDate", Format(Date, "DD-MM-YYYY")
        MsgBox "This is the first and last time today that you are running the macro.", vbInformation
        Call YOUR_MACRO
    
    ElseIf (Date - DateValue(ExDate)) & 0 Then
        MsgBox "This is the next day. Click OK to run the macro.", vbInformation
        SaveSetting "Excel", "Forum", "ExDate", Format(Date, "DD-MM-YYYY")
        Call YOUR_MACRO
    
    Else
        MsgBox "You have already run this macro today. So now you can't.", vbInformation
    
    End If
End Sub


 Explanation:-
Actually, this macro uses Windows registry settings to save current day when the code is run for the first time in a day.
The benefit of using the Registries is that :-
If the user re-downloads the file (having this code inside) on the same computer, even then he will be restricted to run the Main Macro because the ExDate (Current Date) would have already been saved in the windows registry.
I hope you like the concept.
If you have any doubts in implementing it and understanding it then do comment.

Regards,
Vikas Gautam
