To make a 30 days trial application you simply must locate an AVLock Lite control in your main form and to write the following line of code at the OnCreate event:
if not AvLockpro1.execute then Application.Terminate;
That's enough to convert the application in a 30 days trial version.
AllowBackDate : Type: boolean. When this value is True then the user is able to backward the system date to reuse an expired period.
AppCode : Type: dword. Numeric value to identify the application. For default his value is 123456789 but is strongly recommended to assign a different code for each application.
AppName : Type: string. Name assigned to your application. this appear in the title bar of the registration windows. For default this is leave blank.
Authorized : Type: boolean. If True, this mean that the application is temporarily registered.

InstalCode :Type: string; Length: 8. Hexadecimal Strig Value, not visible at design time. When your application run in the user PCs, AVLock Lite calculate a hexadecimal number called INSTAL CODE, distinct one for each PC and calculated in basis of the Hard Disk serial number. This code must be send to you from the users so you can generate with KeyGen.exe the apropiate REGISTRATION CODE for each user. For more information see below the description for the keyGen.Exe utility.
Logo : Type: bitmap. This property allow you to place your own logo into the registration form.
Prompts and Text properties : Type: string. This properties allow you customize and adapt the component to any language, these are: PromptHowTo, PromptSendTo, PromptWait, PromptToRegister, PromptEnterYour, PromptDaysToExpire, PromptAfterExpire, PromptBtnReg, PromptBtnCancel, PromptBtnContinue, PromptSuccessfull, PromptInvalidCode, TextWarning, TextCongratulation and TextExpired.

1) Temporary: This mean that the appliccation is authorized in a limited period of time bounded between two dates who are stored in the BeginDate and EndDate properties. This allow you to rent your application, since through of registration codes you can habilitate new authorized periods as many times as you want.
2) Permanent : This mean that the application is definitively registered without time limit.
Instalcode: Enter here the install code received from you user.
