Manage the Windows System Registry and Register Objects from Microsoft
The Registry control in Total Access Components lets you read and write
Windows registry values, and register objects like DLL and ActiveX files
to the Windows OLE server.
The Windows registry is a structured database of settings used to store
setting and configuration information for Windows and applications. It
separates machine and user level information and has security based on
your Windows login rights.
Overview of the Windows System Registry
To use the Registry control, you need a basic understanding of the
Windows Registry and should be familiar with the Windows REGEDIT.EXE
The registry is organized at the top level with root keys. Each of
these root keys contains sub-keys, which can themselves contain sub-keys
and values. Each value in a key has data associated with it. A value is
identified by three pieces of information:
- Root Key:
- Key Name
- Value Name
Using the Registry Control
Place the Registry control on your Microsoft Access form and call its
methods (there are no properties for this control).
When you invoke a method, you'll need to specify the Root, Key, and
Value names. You can then invoke methods such as:
- GetKeyValue and GetKeyCount
- GetSubKeyString and SetSubKeyCount
- DeleteKey and DeleteKeyValue
Using the Register Method
The Register method lets you easily register a DLL or ActiveX control
by providing the file name. The control automatically updates the
registry with the appropriate entries.
