FIX: Can't Get IBuildProject Interface from Developer Studio

#include <bldauto.h>
IBuildProject* pIBuildProject = NULL;
pIGenericProject->QueryInterface(IID_IBuildProject,
   (void**)&pIBuildProject));
				

RESOLUTION

The fix to this problem consists of a .tlb file to add to the Developer Studio SharedIDE\Bin\IDE folder and a .reg file for properly registering the IBuildProject interface. The registry fix is nondestructive to existing entries, and the type library is additional; it does not overwrite anything.

To implement the fix, you must first create the .tlb file. To do so, follow these steps:

1. Copy the following code from this article and paste it into a text editor, such as Microsoft Notepad. Save the file as IBuildProject.odl.

   // IBuildProject.odl : type library source for IBuildProject.tlb
   
   // This file will be processed by the Make Type Library (mktyplib) tool to
   // produce the type library (IBuildProject.tlb).
   
   [ uuid(48187B40-02D6-11D1-A308-00A0C909E775), version(1.0),
     helpstring ("Type Library to properly register IBuildProject") ]
   library AddIn
   {
     importlib("stdole32.tlb");
     importlib("devshl.dll");
     importlib("ide/devbld.pkg");
   
     [  uuid(96961264-A819-11CF-AD07-00A0C9034965),
   
        helpstring("Represents a group of related files that can include one or more configurations"),
        oleautomation,
        dual
     ]
     interface IBuildProject : IGenericProject
     {
   
        // methods
        [id(0x00000064), propget, helpstring("Returns the set of configurations in this project")]
        HRESULT Configurations([out, retval] IConfigurations** Configurations);
     };
   
   };
   					

2. From a command line in the same folder as the file IBuildProject.odl, type the following command and press ENTER:

   MKTYPLIB IBuildProject.odl

3. Copy the IBuildProject.tlb file (which was created by the previous step) to the folder <Developer Studio installation folder>\SharedIDE\Bin\IDE.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.


Now you must register the modified IBuildProject interface. To do so, follow these steps:

1. Copy the following code and paste it into a text editor, such as Microsoft Notepad.

   Save this file as IBuildProject2.reg.
2. If your Developer Studio installation path is not "C:\Program Files\DevStudio\SharedIDE\BIN\IDE", edit the registry key named [HKEY_CLASSES_ROOT\TypeLib\{48187B40-02D6-11D1-A308-00A0C909E775}\1.0\409\win32] to point to the folder where you copied IBuildProject.odl.
3. From Windows Explorer, open the file IBuildProject2.reg. Click OK when you are prompted to import the file into the registry.
