This issue introduces a class called cRegistryUtils. The functions currently implemented retrieve the Registered User and Organization strings that Windows 95 shows when you go to Control Panel / System. It is also used to in many applications during setup as the default registered user and organization names.
In the future this source code will be enhanced to retrieve and save other useful values in the registry. If you have any suggestions, let us know at http://www.codeoftheweek.com/feedback.html
The two main functions in this issue we will discuss are RegisteredUser and Organization. It retrieves this information by reading the registry keys HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RegisteredOwner and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RegisteredOrganization. Their declarations look like this:
Public Function RegisteredUser() As Variant Public Function Organization() As Variant
RegisteredUser returns the registered user name. Organization returns the organization name. In both functions, if the data can not be found it will return an Empty string. You can check the return value using the built-in IsEmpty function. If IsEmpty returns True, the data was not found.
Below is an example of how this function works. It is assumed that txtOrganization and txtRegisteredUser are type TextBox.
Dim Reg As New cRegistryUtils txtOrganization = Reg.Organization txtRegisteredUser = Reg.RegisteredUser
