FIX: Non-U.S. English DevStudio Typelibs Improperly Registered

MORE INFORMATION

Visual C++ 5.0 introduced a new Automation Model that gives access to a variety of internal data and functions. Four type libraries describe the interfaces to the objects exposed by this model. Installing Visual C++ registers these type libraries with OLE/COM under globally unique IDs (GUIDs). The installation saves the paths to the type libraries under the U.S. English locale code, the code under which they were compiled.

The four libraries and their GUIDs are:

   DSDebugger (devdbg.pkg)       {34C63000-AE64-11CF-AB59-00AA00C091A1}
   DSProjectSystem (devbld.pkg)  {96961265-A819-11CF-AD07-00A0C9034965}
   DSSharedObjects (devshl.dll)  {B3CF8E20-19B6-11CF-8E4D-00AA004254C4}
   DSTextEditor (devedit.pkg)    {2A6DF200-8240-11CF-AB59-00AA00C091A1}
				

Several OLE interfaces (for example, ITypeLib, ITypeLib2) return object and method documentation from type libraries. The following code gets the ITypeLib interface for Visual Studio Shared Objects (Devshl.dll):

   #include <atlbase.h>
   const GUID guidShl
               = { 0xB3CF8E20L, 0x19B6, 0x11CF,
                 { 0x8E, 0x4D, 0x00, 0xAA, 0x00, 0x42, 0x54, 0xC4 } }
   CComPtr<ITypeLib> pTLib;
   HRESULT hr  = LoadRegTypeLib(
      &guidShl,   // REFGUID rguid.
      1,          // Unsigned short wVerMajor.
      0,          // Unsigned short wVerMinor.
      0x409,      // LCID lcid.
      &pTLib );   // ITypeLib FAR* FAR* pptlib.
				

Steps to Reproduce Behavior

1. In OLE/COM Object Viewer, click View and verify that Expert Mode is selected.
2. In the left pane, expand the Type Libraries node.
3. Find the four Visual C++ type libraries:

   Visual Studio 97 Debugger (Ver 1.0): devdbg.pkg
   Visual Studio 97 Project System (Ver 1.0): devbld.pkg
   Visual Studio 97 Shared Objects (Ver 1.0): devshl.dll
   Visual Studio 97 Text Editor (Ver 1.0): devedit.pkg

   The Visual C++, version 6.0 type libraries that work properly are:

   Visual C++ Debugger (Ver 6.0): devdbg.pkg
   Visual C++ Project System (Ver 6.0): devbld.pkg
   Visual C++ Shared Objects (Ver 6.0): devshl.dll
   Visual C++ Text Editor (Ver 6.0): devedit.pkg

4. Double-click the name of the type library.

RESULT: In non-U.S. English systems, OLE/COM Object Viewer fails to display the type library.
