QlmLicense.StoreKeysEx

Stores the license keys on the computer and returns an error message in case of failure. To read keys, use the ReadKeys API. To clear the stored keys, use the DeleteKeys API.

C#:    StoreKeysEx(string activationKey, string computerKey, out bool userLevelResult, out bool machineLevelResult, out string errorMessage)

Parameters

• activationKey- the activation key to store
• computerKey- the computer bound key to store.
• userLevelResult- returned boolean value indicating whether the operation was successful at the user level.
• machineLevelResult- returned boolean value indicating whether the operation was successful at the machine level.
• errorMessage- returned error message containing details about the failure, if any.

StoreKeysEx returns true if either the user level or the machine level operation is successful.

Description

QLM stores its data in two locations: one location at the user level and another location at the machine level. The StoreKeysOptions property controls where data is stored.

Additionally, the StoreKeysLocation property controls whether data is stored on the file system or in the registry.

EFile / Data on the file system

If you are running XP, the folders are:

C:\Documents and Settings\<your account name>\Application Data\IsolatedStorage\*
C:\Documents and Settings\All Users\Application Data\IsolatedStorage

On Windows 7 or higher, the folders are:

C:\ProgramData\IsolatedStorage
C:\Users\tom\AppData\Local\IsolatedStorage

Example on Windows 7 or higher:
C:\ProgramData\IsolatedStorage\1zy03lmk.jql\epxur3qn.na0\StrongName.gziza0ait44cgjtqq2fgdpi3yp0idvio\AssemFiles

Under these folders, a file whose name is the GUID associated to your product (GUID in Define Products page) is created and contains the license keys.

ERegistry / Data in the registry

When QlmLicense.StoreKeysLocation is set to EStoreKeysTo.ERegistry, QLM tries to stores the keys in 2 registry hives, one hive at the user level and one hive at the machine level.

On a 32 bit OS, QLM will write license information to:

• HKEY_CURRENT_USER\Software\Classes\CLSID\[GUID]
• HKEY_LOCAL_MACHINE\Software\Classes\CLSID\[GUID]

On a 64 bit OS, QLM will write license information to:

• HKEY_CURRENT_USER\Software\Classes\CLSID\[GUID]
• HKEY_LOCAL_MACHINE\Software\Classes\CLSID\[GUID]
• HKEY_CURRENT_USER\Software\Wow6432Node\Classes\CLSID\[GUID]
• HKEY_LOCAL_MACHINE\Software\Wow6432Node\Classes\CLSID\[GUID]

EFileCommonData

When selecting this option, license keys are stored in C:\ProgramData\<CommonDataFolder>\>CommonDataFileName>

where :

CommonDataFolder = Product Name or the value configured in the Protect Your App wizard

CommonDataFileName = license.txt or the value configured in the Protect Your App wizard
