I'm in the process of writing a plugin for LDraw Design Pad. Problem is, I can't
get the darn thing to work in the program. When I compile the .dll and move it
to the Plugins directory for LDDP, and open the program, the menu entry for my
plugin shows 3 characters of garbage text; so does its description. There seems
to be no indication that the Plugin_Info() function is called correctly at all.
I think the problem is with the declaration. LDDP's sample C++ plugin is
designed for Borland, and I'm using Microsoft Visual C++. This is the spec for
the original:
extern "C" void WINAPI __declspec(dllexport) Plugin_Info(unsigned char CaseID,
char *buffer, unsigned char maxlength)
That doesn't compile for me; the compiler freaks out about one of those
keywords. If I move WINAPI to after __declspec(), it compiles, but then the
plugin just doesn't work at all (producing the garbage text I mentioned above).
I've tried various combinations of things, including removing the extern "C"
bit, but nothing works. Has anyone successfully compiled an LDDP plugin with
VC++ who can explain what I need to change?

| Please disregard the previous message. I was able to compile and use the plugin by creating a .def file, and using this syntax: extern "C" void __declspec(dllexport) WINAPI Plugin_Info(unsigned char CaseID, char *buffer, unsigned char maxlength) (...) (18 years ago, 28-Oct-06, to lugnet.cad)
