visual studio - Trying to convert Delphi interface definition to C++ for VS 2008 -
i need convert interface defined in delpi c++. made small demo project contains of stuff shown below.
first delphi function person claims working on this thread:
function canfilebedeletedtorecyclebin(const afilename: unicodestring): boolean; var recyclebinmanager: irecyclebinmanager; begin olecheck(cocreateinstance(clsid_recyclebinmanager, nil, clsctx_inproc_server or clsctx_local_server, irecyclebinmanager, recyclebinmanager)); try result := recyclebinmanager.willrecycle(pwidechar(afilename)) = s_ok; recyclebinmanager := nil; end; end; the rest of delphi interface definitions are here.
so came following c++ code unfortunately crashes. (again, let me repeat person wrote delphi version claims works fine him.)
hresult hr; coinitializeex(null, coinit_disable_ole1dde | coinit_apartmentthreaded); // {4a04656d-52aa-49de-8a09-cb178760e748} const clsid clsid_recyclebinmanager = {0x4a04656d, 0x52aa, 0x49de, {0x8a, 0x09, 0xcb, 0x17, 0x87, 0x60, 0xe7, 0x48}}; // {5869092d-8af9-4a6c-ae84-1f03be2246cc} const iid iid_irecyclebinmanager = {0x5869092d, 0x8af9, 0x4a6c, {0xae, 0x84, 0x1f, 0x03, 0xbe, 0x22, 0x46, 0xcc}}; irecyclebinmanager* pirbm = null; hr = cocreateinstance(clsid_recyclebinmanager, null, clsctx_inproc_server | clsctx_local_server, iid_irecyclebinmanager, (void**) &pirbm); // hr = shcocreateinstance(null, &clsid_recyclebinmanager, null, iid_irecyclebinmanager, (void **)&pirbm); if (succeeded(hr)) { //i crash on next line: //unhandled exception @ 0x76175ed2: 0xc0000005: access violation writing location 0xa84d252b. hr = pirbm->willrecycle(l"c:\\test del"); pirbm->release(); } i tried best convert interface delphi (here) c++. here's got (after @remylebeau's suggestions, unfortunately still didn't work me.)

rather translating interface code delphi c++, can take original code russian site, put in .pas file as-is, , add file c++ project. when build project (or compile .pas file itself), c++ .hpp file generated you, can #include c++ code.
doing way, following code works fine me in c++builder xe2 on windows 7:
#include "urecyclebinstuff.hpp" #include <comobj.hpp> bool __fastcall canfilebedeletedtorecyclebin(const unicodestring &afilename) { delphiinterface<irecyclebinmanager> recyclebinmanager; olecheck(cocreateinstance(clsid_recyclebinmanager, null, clsctx_inproc_server | clsctx_local_server, iid_irecyclebinmanager, (void**)&recyclebinmanager)); return (recyclebinmanager->willrecycle(afilename.c_str()) == s_ok); } void __fastcall tform1::button1click(tobject *sender) { if (canfilebedeletedtorecyclebin(l"c:\\test del")) showmessage("can deleted"); // <-- code makes here else showmessage("can not deleted"); } here generated .hpp file looks like:
