Protect a Xojo Windows app with QLM

QLM can protect a Xojo Windows app.

A Xojo sample can be found in the following folder:

 C:\Users\Public\Documents\Quick License Manager\Samples\qlmpro\Windows\Xojo

 We highly recommend that you familiarize yourself with the sample before protecting your own application.

To protect your Xojo Windows application with QLM:

• Copy the LicenseValidator class from the Xojo sample to your Xojo app
• Copy the following files from C:\Users\Public\Documents\Quick License Manager\Samples\qlmpro\Windows\Xojo folder to your Xojo project. 
• QlmLicenseLib.dll
• QlmWrapper.dll
• QlmLicenseWizard.exe
• register.bat
• Open a command prompt as Administrator (Run As Administrator) and execute register.bat. Make sure the registration is successful before proceeding.
• In the Xojo IDE, click Insert / Active X Component, go to the References tab, locate QlmWrapper.dll, select it and click Ok. 
• Locate the InitializeLicense method of the LicenseValidator class and update the following to to match your own product:
• Update all arguments of the call to DefineProduct
• Update the PublicKey
• Update the DefaultWebServiceUrl
• Update the CommunicationEncryptionKey
• When your app starts up, call the ValidateLicenseAtSartup method of the LicenseValidator class.
• If ValidateLicenseAtStartup fails, launch the QLM License Wizard process to prompt the user to enter his Activation Key.
• Right after the QLM License Wizard process returns, call ValidateLicenseAtSartup again. If the call fails, exit your application. If the call succeeds, proceed to launch your application.
