Since JavaScript is a dynamically-typed language, you may wish to use the following code to handle all types of data. The data types supported by this interface are defined as named constants on the interface as follows:Įach of these types (except TYPE_NONE) has a corresponding method to read the value data: This method returns an integer indicating the data type of the value. You can check the type of a value using the method getValueType().

However, Windows registry values can have several data types, so you need to ensure that you read the correct type.

The simple example above shows how to read an existing string value. Probably the most common action associated with the Windows registry is reading values.

Once you've opened a registry key, you can begin to make use of it. Var id = subkey.readStringValue("ProductId") Here's the simple example again, but using openChild(): var wrk = subkey = wrk.openChild("Windows\\CurrentVersion", wrk.ACCESS_READ) Both methods take a relative path and access mode as parameters and return a new object implementing nsIWindowsRegKey. You can call these methods on an already-opened registry key to open a child key. In addition to open() and create(), there are the openChild() and createChild() methods.

You can read the interface documentation for a full explanation, but we will show only the three most commonly used modes here: It is specified as a bitwise combination of flags defined on the interface. The third parameter for open() and create() is the access mode. As noted in the example above, you will need to escape backslashes within the string. The second parameter for open() and create() is the path to the key. ROOT_KEY_LOCAL_MACHINE - Corresponds to HKEY_LOCAL_MACHINE.ROOT_KEY_CURRENT_USER - Corresponds to HKEY_CURRENT_USER.ROOT_KEY_CLASSES_ROOT - Corresponds to HKEY_CLASSES_ROOT.From JavaScript, you will want to use the named constants on the interface for this parameter. Note that it is not an error to call create() on an existing key, and doing so has the same result as calling open().īoth of these methods take a root key as the first parameter.

If you want to create a new key, you can use the create() method, which takes the same parameters as open(). The example above demonstates this using the open() method. Opening Registry Keysīefore doing anything with a registry key you must first open the key you are interested in. Finally, note that you should close the key when you are done to avoid wasting system resources. You have to specify what type of data you expect to read, which we will expand on later. The value is read using readStringValue(). This can be very important when dealing with non-Administrator accounts with restricted privileges. The desired access rights are specified using a named constant from the interface, in this example ACCESS_READ. Also notice that the path to the key has backslashes escaped, a necessity in JavaScript and C++ string constants. Notice in the open() call that the root key to use is specified using the named constants available on the nsIWindowsRegKey interface, in this case ROOT_KEY_LOCAL_MACHINE, which corresponds to HKEY_LOCAL_MACHINE in the Windows registry. Second, you must call open() on the key before attempting to read a value. First, you must use createInstance() to get an object implementing this interface, not getService().

This example, while simple, shows several important things about using the interface. Here's a simple example showing how to read your Windows ProductId: var wrk = id = wrk.readStringValue("ProductId") If you are writing an extension that only needs to support Firefox 1.5 or newer, then you only need to read this section. The interface follows the Windows API fairly closely, but with many of the low-level details taken care of for you. In Firefox 1.5, a new API was added, nsIWindowsRegKey, which provides extensive registry functionality. The examples in this document are all written in JavaScript using XPCOM. This article will show you how to use the available interfaces in several Mozilla products. To this end, there exist XPCOM interfaces to read and write registry data. When implementing Windows-specific functionality, it is often useful to access the Windows registry for information about the environment or other installed programs.
