Create Trial/Demo version of workbook or add-in
With DoneEx VbaCompiler for Excel you may create a trial / demo version of your workbook or Excel Add-In.
The main difference of such a trial version that it is limited by the amount of days from the moment it is first started on the customer’s computer.
After the expiration of the trial period of this trial workbook or add-in, it stops working and shows a message reminding the user about registration.
Once the trial period has expired, only applying registration key will the user be able to continue to work with the workbook or add-in.
To create a Trial/Demo version of the workbook or Excel add-in you need to compile the VBA code with the “Copy protection with registration key” option enabled and the “Trial mode” option enabled.
When you select “Trial version” option the “Trial Version Options” dialog window will be shown.
In the “Trial Version Options” dialog you may change trial version options, which originally have the suggested values by default.
The “Trial expires in XX days” option allows you to change the amount of trial days in the range from 1 to 99.
This many days after the user’s first launch of the application the trial period ends. After the trial period ends, the user will not be able to use the application without applying the appropriate registration key.
The “Close button appears in XX seconds” option controls the delay before “Close” button will be shown on trial warning window during the trial period. You can set value of the delay time in the range from 0 to 15 seconds.
After you select the trial version options and click on the “OK” button, the options that were selected will be set for your VBA code compilation.
Select “Compile” main menu option and wait until the workbook or add-in is compiled.
When your customer runs the trial version of the workbook, they will see the following warning:
Only after closing this trial warning window will the customer be able to continue working with the application.
After the set amount of trial days has expired, the customer will get the following message when they try to run the trial workbook or add-in.
After closing this message the trial workbook will be automatically closed and will not be available for work.
In the case that somebody will try to move the system clock back to restart the trial period, the run-time procedure will verify the current data through the Internet on public time servers.
If the user tries to disable internet to block this date/time verification procedure then the following message appears:
After you generate the registration key and put it into the folder where dll file with the compiled VBA code is located— the workbook will open without a trial message and will continue to work in its registered mode.
