JOB SECURITY- How To Make A VBA Script Expire

Apr 20, 2007

method for making a VBA script expire?

I.e. it will only work for a specified time and requires the author of the script to renew it at a given point?

I want to be able to do this to strengthen my position as an independent contrator financially...and copy protect my work from unwanted exploitation

Some ideas:
1-MSG box requesting a pre-defined password to renew the time for the script to work along with contact info for the author

2-Ability to define # of days, months and or years the script will work

3-Ability to define the # of days, months and or years that a MSG box warning of pending expiration will appear

4Ability to define the # of days, months and or years that the renew will extend the use of the script with multiple pre-defined passwords allowing different lengths of time extention! Perhaps an encryption method allows you to in another excel sheet (say the comfort of your own home) generate at will a password that will extend a scripts life for 3 months?! They contact you again, and again you generate a "random" password that will extend the original script

5-Anti-hacking measures, using MS's built in security

This might be a useful way of extracting monies over time, for the use of a script you provide....pre-set

How To Make Excel Spreadsheet Access Expire

Feb 15, 2014

I recall a few years ago that I located a program that allowed me to create an Excel spreadsheet and share it with others, but that locked the spreadsheet after a given period of time. I need to create a spreadsheet, but I want to put a time frame on it which requires users to request an access code from me every so many days. I don't want users in my business to be able to take the spreadsheet and use it should they leave the company. I know there was a subscription program that allowed me to do this, but I can't recall the name of it. It also allowed Excel to hide all of the formulas, even though the calculations worked.

I have a raw of data consists of expire date. I would like the excel to control the first expire first out by highlighting the nearest expire date for each materials.

Note that for each materials there are several batch with different expire date. I want the excel to highlight to me which batch i should use first base on nearest expire date. And also highlight in different color if the batch had expired.

Example is attached. I had manually highlight suggest batch to use in yellow, and expired batch in red. How should i do it with formula? Perhaps with "conditional formatting"?

Calculate Time (yr,mth,dy) Left To Expire?

Mar 11, 2009

I have products that have a 3 year shelf life from date of package, I've got:

Col A: code of product.
Col B: date of package.
Col C: expiry date.
Col D: I would like to construct an if statement which will state:

Condition 1: that if expiry date (Col C) is less than current date (today()) then to display "expired by x years, y months and z days" with reference to the current date - using pearson's DATEDIF formula:

"Expired by "&DATEDIF(C2,TODAY(),"y")&" years "&DATEDIF(C2,TODAY(),"ym")&" months "&DATEDIF(C2,TODAY(),"md")&" days"

Condition 2: that if expiry date (Col C) is greater than current date (today()) then to display "in date - x years, y months, z days left to expire" I'm unsure as to how to construct the second formula - as it will be a countdown date difference from the current date to the expiry date? Final if statement will be:
If(C2<=Today(),formula for condition 1 as shown above,formula for condition 2)

Date Expire And Password Reset

Apr 30, 2007

I have an excel file with several worksheets and 1000's of lines of data.

Protection is already given courtesy of having to enable macros or sheets are hidden, and copying of data is not possible. It is however unfortunately possible to copy the excel file, therefore I would like to have code to to render the file inoperative if a date elapses. In addition since the file is password protected (as regards alterations - read only for others), I would like the clock to increment for example 7 days further every time the correct password is entered. In other words if the time period elapses simply entering the password will reset the clock and permit all users access for another week once the file is saved..

Macro Security (saying That The Macro Security Level Is Too High)

Nov 18, 2008

I have a sheet that will not let me use macros. I can record them, but when I go to use them it says that the Macro security level is too high. I change it to Medium or Low but it doesn't make a difference.

The same spreadsheet works with Macros on another computer, but not my main one.

Are You Sure - Security For Macro

Aug 7, 2007

I have a spreadsheet that I regularly have to clear the data and start over on, so i recorded a macro for clearing this rather long sheet with only one cllick.

My problem is that i am not the only person who will use this sheet, if They click the control button by mistake they will clear their work and you cannot undo it. I was wondering if i could make it ask "are you sure" kind of like the save option when closing an unsaved document.

VBA Security Options

Oct 12, 2009

We have developed an Excel workbook with hundreds of lines of VBA code written for a specific application, and we would like to protect it.

Could someone give me an idea of what security options we have over and above the below (if any)?

We have protected all sheets and the workbook itself with passwords. The VBA itself is protected with a passoword.

My understanding is that VBA can be hacked into quite easily.....is there any way of adding another layer of security/protection without having to move to another platform altogether?

Security Code Input

Dec 7, 2009

If I have a cell which has been validated and has a drop down list of 4 names in it.
I need it to prompt the user that when they choose there name and select, a window pop up or similar window appears asking for a 4 digit(or similar) code.

This is to stop others using peoples names against jobs they have completed so there is accountability if there are issues with information.

For each line I need it to re-prompt the user to enter the 4 digit pin so it cannot be tampered with.

Can anyone help with sending through a form and VB code possibly which I can copy into my spread sheet or a method I can use!

Cell Value Security Check

Apr 10, 2007

There are 2 cells on my spreadsheet where individuals must populate $ values. I want to put a security feature in the worksheet that would create a pop up warning to the user that one cell must be greater than the other.

B26 (Client Assets) must be greater than B41 (Dollar Impact), otherwise a dialog box pops up to indicate to the user that B41 cannot be greater than
B26.

Make Userform Show Data From Spreadsheet And Add Delete Or Make New Entry

Jan 24, 2014

I have a spreadsheet on sheet 1 with a list of customers and their information. So on column A I have the customer number (i.e. k968, e37, p528,...), on column B i have the customer's name, on column C the street's name, on Column D the house number, on column E the zip code and finally the city on column F.

Right now there are around 600 customers in this list.

I have made a userform with a combobox in which I want to select an existing customer (pulled from the spreadsheet). On the same userform I have textboxes (customer number, name, street, number, zip, city). When I select a customer in the combobox, I want this customer's info to show up in the textboxes. I want to be able to change the info and hit Next to store the changes in the spreadsheet. When I do not select a customer from the combobox, I want to add new info in the textboxes and hit Next to store this info as a new customer. The userform also has a delete button. Then I select a customer in the combobox, this customer (and it's info) should be deleted from the spreadsheet when i hit Delete. So the spreadsheet is variable in length.

Security Warning (Macros Have Been Disabled)

Apr 28, 2008

I was playing around with Macros on an excel file. I created a few and ran them. In the end, I didn't like the way they ran, so I deleted them all. However since I ran them in the excel file, every time I open the file it gives me a warning saying
"Macros have been disabled."

Is there any way to remove the possible Macros ties/links from my file? I know I can disable the warning, but if I just want to remove the Macros ties to my file.

VBA To Determine If Federal ID Or Social Security #

Jan 29, 2010

What would be the simplest VBA to determine if a cell E7 contains:

A federal ID always 9 digits with only one hyphen which is always after the 1st two numbers. For example: 12-3456789

or

A social security number always 9 digits with only two hyphens which are always 1 hyphen after the 1st 3 numbers & the other hyphen after the next 2 numbers. For example 123-45-6789.

In other words,

If Range("E7") = a federal id then
or
If Range("E7") = a social security number then

Sort Out All Bid Prices For A Specific Security

Jan 4, 2006

I have a security order list. This consist of several columns most important are

Column A Column B

Sec a 15,00
Sec b 14,50
Sec c 16,00
Sec a 15,10
Sec a 15,70
Sec b 16,70
Sec a 14,80

The first column gives the name of the security, the second column gives the bid price.

What I want is that I want to sort out all bid prices for a specific security. Vlookup works fine but again it just gives the first record. How can I get all bid prices for security a on a new worksheet without blank cells. If possible I would like to have it sorted as well.

Xl Macro Cant Email Due To Outlook Security

Jul 3, 2002

I've written code into excel that sends workbooks to email recipients. This works fine except for use on one friends computer. Of course it's the friend that needed the code in the first place.
What happens is that when the macro attempts to mail a spreadsheet an outlook popup occurrs warning that a macro is attempting to email a message. And so nothing gets emailed out!

Macro To Compare Security Codes

Jul 18, 2008

I have 4 worksheets in a workbook: “choose security”, “download”, “MC” and “Lending”,

In the choose security” worksheet in CELL A2 is an HEX code, i.e. stock code.

2. In MC worksheet is raw data of all holdings related to various p’folios and securities, the information we need from this worksheet is,

a) p’folios, which are in column A,
b) Holdings which is Col B
c) Security code i.e. stock code which is in Col D

I need a macro or a formula to look at what security code is in “choose security” worksheet CELL A2, then look for this security in worksheet “MC” Col D, once matched, copy the data for this security to worksheet “download” and paste in CELL A3, I only need p’folios and holdings to be copied to “download” so data in Col A and B.

Once data has been copied to worksheet “download”, I then need another macro or formula to repeat step 2, but this time the macro will be looking at worksheet “Lending”,

a) P’folios, which are in Col B
b) Security code is in Col D
c) Holdings is in Col H

Once the macro or formula has found a match of security code, it will then copy the data from Col B and H to download worksheet CELL E3.

Active Workbook Refreshall Security

Nov 4, 2008

I have a function that is called in Access vba code that refreshes all sheets in a given workbook. We use it all the time for workbooks containing any number of tabs to be refreshed. The code has a key line: ActiveWroksheet.Refreshall. I need to now start to secure the pivot so the user can not refresh it. Another post pointed me towards: .PivotCache.EnableRefresh = False.

This apparently can only be used for a particular sheet; ie it can not be applied to ALL sheets in the workbook. The trouble is the function is generically used to refresh any workbook, and the number of sheets may vary.

Any thoughts on how I can disable the ability to refresh a pivot for ALL sheets. I'd prefer not to turn off the pivot wizard since the user should be allowed to manipulate it...just not refresh it.

Trusted Macro Regardless Of Security Setting

I've been told the latest Excels will allow any workbooks in a certain folder
to run macros as trusted (regardless of security setting?).

Can anyone confirm this please? Is there more to it? What versions are affected? Mine is 2003 so I can't check for this.
