Include a "timebomb"
I produce a number of quite complex spreadsheets for a number of clients. One client is due to change suppliers at the end of the year and currently recieves a very large amount of management information from us via the spreadsheets. It might sound like "sour grapes" but after they change suppliers I do not want the new supplier to simply pick up my spreadsheets and continue to provide the same management information without having any of the cost/headaches associated with producing the spreadsheets. Is there a way, perhaps using the date, to set the formulas to automatically delete themselves after a given date? I have no problem with the format or data - it's just removing the formulas. Logic says I should have password protected the files in the beginning ... hindsight is a great thing! I think that I am right in believing that I am not breaking any laws etc. (and I certainly don't want to even think about viruii). The iinformation is supplied as a service for which there is no charge. Any advice would be appreicated.

set up a macro which runs at opening. when if the date is greater than your
data of interest select all in each sheet, copies and pastes special-value. I would also have it delete all modules except the module including this macro. and have it close the file so that they can't just do undo. you need to have a rweset in the macro so it only runs once and they can then opn the file with the data as text only.

Why? Didn't your customer pay for your services? If so, haven't they become the rightful owner of said spreadsheets? -- It is I, DeauDeau (Free after monsieur Leclerc in 'Allo, 'allo) |

Insufficient. A user can always open a spreadsheet in Office Safe Mode and
avoid miscreant macros. -- Gary's Student "bj" wrote: set up a macro which runs at opening. when if the date is greater than your data of interest select all in each sheet, copies and pastes special-value.

it could be done but only on any new spreadsheets you send them.
wouldn't they have all the older spreadsheets you sent them? the older spread sheets would still have the formulas. regards FSt1 "y_not" wrote: I produce a number of quite complex spreadsheets for a number of clients.

I would caution you to consider the impact of "burning your bridges" as it were. If you screw with this client, not only do you assure they will <never utilize your services again, you also assure that they will give you bad word of mouth advertising. A better idea may be to turn this into a PR plus. Let them know you are not "locking down" your spreadsheets and that they are free to continue to utilize them. Most likely the new vendor will have their own system anyway, and won't need or want to utilize yours (they probably sold themselves as having a better system). Plus, all they need is a backup laying around once they figure out what you've done, alter the system date on a pc, open the file and modify your code.... Just my opinion, for what its worth...

: Absolutely not! Oh my! Did I say something wrong? A consultant is paid for his knowledge, expertise and abilities. The intellectual material that he/she develops as a tool to solve a client's issues are the property of the consultant unless stated otherwise in the contract between the consultant and the client. The consultant is selling his time not products. It depends on the contract, then. A bit of foresight is the trademark of a good consultant? ;-))) -- It is I, DeauDeau (Free after monsieur Leclerc in 'Allo, 'allo) |
