I am evaluating the product for you and so far I am finding it amazing! I'm having some difficulties in testing mode WLM, you could give me an example of the function VMProtectActivateLicense with Delphi?
The way I'm using I can activate the following code in
http://weblm.vmpsoft.com (Product # 89), however, I get a generic error BEX and the program ends at this point.
...
var
SerialNumber: PAnsiChar;
begin
ActivateState: VMProtectActivateLicense = ("IZR2-VLDM-GXDZ '
SerialNumber,
Round (4096/8 * 3/2 + 10));
end;
Thank you for your support.

Code: Select all
var Buf:array [0..1023] of AnsiChar;
State: Integer;
begin
State := VMProtectActivateLicense('IZR2-VLDM-GXDZ', Buf, SizeOf(Buf));
if State=0 then
edSerial.Text:=Buf
else
MessageDlg(Format('Activation error: %d',[State]),mtError,[mbOk],0);
end;

It worked perfectly!
Now I'm having trouble activating the codes for certain modes of the product.
If I activate an activation code for the product # 89 works, but if I activate an activation code to the way "30 days free trial" get the status 2 at the time of setting the serial number. And strangely when I check the serial number generated
http://weblm.vmpsoft.com get an error saying "Serial number parsing error".
Thanks for your support.

Thanks for your report. The bug in WebLM is fixed.
P.S. For trial activation code you can use unlimited activation count (the value of "Activations Count" can be empty).

Again, it worked perfectly!
I really like the speed bug fix.
Now that my application is "integrated" with the VMProtect I have some conceptual doubts, see if you can help me:
I like to do in my application a licensing process similar to Kaspersky, for example, the application itself must generate an activation code (trial) on the first run. Is this possible? Is there any API for this step?
I realized that if I manually lock a serial number and reactivate my application WLM will generate another serial number. How do I put a serial number on the blacklist and prevent the application to work in a particular customer?
PS.: If I register a unique activation code with unlimited activations will look like the name and e-mail since it will already be informed in the code? His suggestion was just to test or is as it should be used?
Thank you for support.

You don't need this. Just generate an unlimited activation code and put it to your application. At the first run you do the activation using that code, WebLM checks the database for such HWID and either generates a new serial number for the fresh activation, or returns an existing one. So the user can't activate twice to get a new trial, for example.

But in this case the name and e-mail customer will always be the same for trial activations, right? Is there a way to activate the code by the application with the name and e-mail each customer?

That feature is not (yet) supported, you may try to put your server between the application and WebLM, so it acts like a proxy and saves name/serial number pairs to your own database. Our vision so far is that trials should be anonymous.
