Trial version for ms Access file (.mde)

[Asher David]

Hi,

How can I possibly make a trial version on my access file before i compiled it to .mde file..

I have done it to Ms excel where the VBA I made is referring to cell(1,1) which is hidden. This cell(1,1) are referring to date. Once the date deadline was reached my program will put a data in the cell(1,1) and automatically saved it and close the application. So meaning even the user change the date of the computer the next time he use my application it will not work anymore..

How can I possibly do it in MS access? Like let say Table 1 (column1 row1) referring to date , then then (column2, row1) will have a value.

Thanks!

There are plenty of ways you can do it...

1) make use of registry, or
2) store the encrypted date in the text file, or
3) strore encrypted date in an encrypted database and so on...

there can be several possiblities..

Sounds good for number 1 and number 2. Any idea what website/link for me to look that I might start learning your suggestion? You know Im really so new in making a registry or something. But Im so interested on your suggestion.

If you do a search in vbforums, you will come across plenty of examples for registry handling...

Note: Make a bakup of your registry before you try anything...

Again same goes for encryption. do a search in this forum and you will get plenty of examples...

Hope this helps...
