Exploring Windows Type Libraries
Go Up to How To Manage Files and Folders
You can open and inspect the interfaces and other types contained within a Windows type library. The type library contents are displayed in a Windows Explorer-style presentation, with a left pane containing a tree of the interface and type definitions within the type library. The right pane displays specific information on the selected item in the tree. The Type Library Explorer can open a .TLB file, as well as OCX controls, and .DLL and .EXE files that have type libraries as embedded resources.
To Inspect a Windows Type Library
- Choose File > Open.
- In the Open dialog box, from the Files of type drop-down list, select Type Library. This sets the file filter to display files with extensions of .TLB, .OLB, .OCX, .DLL, and .EXE.
- Navigate to the folder where the type library is located.
- Select the file and click Open.
