Writes data into a QLM cookie. To read keys, use the ReadCookie API.
C#: bool StoreCookie(string data, string cookieName, int index, out bool userLevelResult, out bool machineLevelResult, out string errorMessage)
StoreCookie returns true if either the user level or the machine level operation is successful.
- data - the data to write
- cookieName - a unique name for the cookie
- index - the index of the element to write. You can write multiple entries into a iven cookie.
- 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.
QLM can store 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.
