This page provides downloads for the Type Libraries used in the samples on this site and also
provides information for writing your own Type Libraries. All Type Libraries come with complete
source code.
Note: Type Libraries follow the same rules as other COM objects: if you modify the code and
rebuild the type library, you must change also change the CLSID, the Type Library Name and the
Type Library Filename to prevent clashing with other user's work.

This Type Library provides access to COM interfaces used by the Shell to show
folder and file lists. The following interfaces are exposed:
IContextMenu
IContextMenu2
IContextMenu3
IEnumIDList
IMalloc
IOleWindow
IShellDetails
IShellView
IShellView2
IUnknown
To see the Type Library in use, check out Brad Martinez's excellent EnumDeskVB sample at his
web site, Brad's VB-32 Programs & Samples.
vbAccelerator samples use the IMalloc and IUnknown interfaces.

ThreadAPI - API Calls Used for Threading
|
| |
VB5 and 6 can be used to develop free-threaded DLLs. However, once a new thread has been created
you cannot run any VB code at all until the first object has been created on it. This Type Library
provides all the Win32 API and COM calls required to initialise an object into a new thread. It
also provides a good demonstration of how to translate Win32 API calls into Type Library calls.
Supported calls:
- OLE32
CoMarshalInterThreadInterfaceInStream, CoGetInterfaceAndReleaseStream, CLSIDFromProgID, CoInitialize, CoUninitialize, IIDFromString, CoCreateInstance
- Kernel32
WaitForSingleObject, CreateEvent, CloseHandle, PulseEvent, SetEvent, ResetEvent, ResumeThread, SuspendThread,
InterlockedIncrement, InterlockedDecrement, WaitForMultipleObjects, GetCurrentThreadID, GetCurrentProcessId , GetCurrentProcess, CreateThread ,
CopyMemory, ZeroMemory, Sleep, InitializeCriticalSection, EnterCriticalSection, LeaveCriticalSection, DuplicateHandle,
GetExitCodeThread
- User32
PeekMessage, TranslateMessage, DispatchMessage, EnumThreadWindows, GetClassName

Shell Extension Interfaces v1.01 - Eduardo Morcillo
|

This Type Library is provided at Eduardo Morcillo's excellent VB site, Edanmo's VB Page.
On the site it is used to generate a whole array of shell extensions in VB.
Supported calls:
- IContextMenu
- IContextMenu2
- IDataObject
- IDropTarget
- IEnumFORMATETC
- IExtractIcon (ANSI and Unicode)
- IPersistFile
- IShellExecuteHook (ANSI and Unicode)
- IShellExtInit
- IShellPropSheetExt
To see the type library in use, check out the RichEdit 3.0
Text Object Model sample, which uses it to access the OLE IDataObject interface to transfer
information in RTF format from the RichEdit 3.0 control.

This Type Library was originally provided with the CodeFlow sample from the
VB Owner's Area at MSDN. It contains only one interface declaration (which could equally be written in VB
as a class) but does allow an ActiveX object to be created without its public interface
being cluttered with items the user of the object does not care about.
Supported calls:

article.

Type Library Utilities
|
VB Type Library registration utility
|
| |
This all-VB application uses the registry, OLE interfaces and TLBINF32.DLL to allow you to
register, unregister and check the condition of your Type Library registrations.
|
|
|
GUID Generation
|
| |
If you don't have Microsoft's GUIDGen.EXE then here is an alternative, implemented in VB by
Dion Wiggins.
