36 * generating your own version from the elusive binary .tlb file takes a lot of
37 * hacking and results in a 3MB header file (!), we opt for this slightly
38 * voodoo approach. The following is just enough definition to be able to
39 * reach the _AppDomain::CreateInstance method that we need to use to be able
40 * to fire up .Net objects. We used to use IDispatch for this, but it would
41 * not always work.
42 *
43 * The following info was obtained using OleView to export the IDL from
44 * mscorlib.tlb. Note that OleView is unable to generate C headers for this
45 * particular tlb... hence this mess.
