hi everybody!
i'm making an addin that will be selled.
1st.
i want make a trial version that will be working just 15 days. i want that on the first use of a certain botton the date will be stored in a global variable
, then i'll put an if statement to control the date and i'll make the addin not working. the problem is how can i store the date, without loose it on exit? i want it to be stored permanently in the addin.
2nd.
i want to make a registration userform where will be displayed the unique serial number of the addin (then i'll make an algorithm to produce the key)
i thouhgt to use ip adress (i already have the code to obtain the ip address) to originate the serial number, then the user must refer this number and i'll provide the key.
i want to input the key in a textbox and then, by pressing a button, make this textbox unselectable and unchangable...the problem is (like before) i can make this permanent change in the userform, without reset the userform each time the addin is loaded?
thanks to everybody,
and sorry for my english ;-) i tried my best
