#704 Heat throws "Bad Image" error on typelibs.

heat (135)

Not sure why but all the TLB files (created
internally) which are harvested by heat all throw
a "Bad Image" error.

Version: 3.0.2218.0

    Check the tool you're generating the type libraries with. I get a
    TYPE_E_CANTLOADLIBRARY error when trying to open the attached type library with
    oleview.exe (from the Platform SDK/VS2005). The problem seems to be in the coclass.

    If that tool cannot open it, it's very likely malformed.

    Thanks Mike. The file was created with VB6. I can open the file happily with my copy of oleview (v2.10.054)

    I have the same problem with a type library generated with MIDL. From checking the source, the problem is coming from the native LoadLibraryEx call. LoadLibrary(Ex) will display an error message box whenever you attempt to load a non-DLL image file. Since the code in UtilHarvesterMutator attempts to load the file first as a regular DLL then as a TLB if that fails, you get the message box before it will continue successfully processing the TLB.

    Probably should add an explicit file extension check (.TLB) before running it through the DllHarvester.
