Thanks for your answer. I tried the solutions mentioned ( /Zl is edit and continue debug info ) and /entry without success. I am looking for stuff from Grimes. I think the local bookstore has a copy of his .Net book maybe that has some answers. In the mean time building an unmanaged dll and calling it from the managed code is ok but not good answer.

I dimly remember seeing an article - can't find it now - by Richard Grimes(? maybe). The gist of it was that a bug in the compiler/libraries could hit .NET programs that use the C++ STL classes. I think the recipe was - Remove the /Zl option (that was lower case L not numeral 1) from the compiler options and remove the /entry option from the linker options. I can't recall what these options do or why they fixed the (described) problem. I have not tried it with BGL code. I certainly dont know if they will help you - but good luck. - Richard -----Original Message----- From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Bill Eidson Sent: 03 August 2004 19:50 To: boost-users@lists.boost.org Subject: [Boost-users] BGL in mangaged C++ (.Net ) Has anyone had success running the BGL from with managed C++ code? I have code that compiles fine, but at runtime throws a .Net exception called TypeLoadException. Googleing and documentation I have read are no help. The graph used is a plain vanilla adjacency_list<> and the exception occurs durring the resize operation of the vertex vector. thanks in advance bille _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users --- Incoming mail is certified Virus Free.
