I need a database programmer who knows how to manipulate excel files in such a way that he/she will be able to do all of the things listed below 1. Add password to an excel file such that the client will not be able to change or remov the password 2. Ensure that the excel file expires after a period e.g 1 year. It should not be possible for the client to manipulate the computer date or the macro to by-pass thisSent on:12:54 pm 3. Since the client knows that the excel file will expire, he would definately copy the contents into another program e.g Access or SPSS. what i want is that when he copy to another file e.g SPSS, the data in the new SPSS file should also expire after the specified period. i.e It is more of content protection that file protection.

Hi, i can help you in this project but in different way, as what you are asking in Excel is NOT possible, as for me i can crack the excel password in 3 min. Relevant Skills and Experience so the idea is to have a tool (windows) application that will allow the user to view the data but not copy it. and you can add expiry and this can be configured online. Proposed Milestones $750 USD - we can discuses about this but its project minimum :)

I hope we can reach some advantageous arrangement, I am an Excel Access designer, The password is not complicated. But something expiration, what you can is take time internet, and as for content content is complicated but I can do some tricks that avoid it, it will depend on the content. Because there is information that can be encrypted, another to make an image and another is that with variables hit statements so that when copied memory is erased. Htos propuestos $750 USD - excel this offer I can better price.

Expert In Excel Macro creation I have created several excel macros and i am highly proficient with Excel VBA knowledge. I have created 2 major macros which are being used in the IT companies. 1. I created 1 macro to link the defects to different test cases in Quality Center. The process used to take 1-2 hours and a lot of efforts manually but with the macro, the defects linking takes hardly 30-40 seconds. 2. I have created one macro for the HR departments where they wanted to collect the data from different employees from different department and consolidate their data depending upon the project on which they are working, whether they are on bench or not.. etc. The macro reduced the whole effort to hardly 40 seconds. I have a principle and i work on that only- 'Serve the Best'
