Hi everyone:

*MyPlugin

|--------------A.dll(third party dll)

|--------------B.dll(third party dll)

*MyPlugin_Entrance-----real add-on,including CheckEnvironment\RegisterInterface\Initialize\FreeData

1,Above is my project structure.

2,Part of the code in MyPlugin is as follows:

extern "C" _declspec(dllexport) void Export() { API_ProjectInfo project_info; auto err = ACAPI_ProjectOperation_Project(&project_info); err = NoError; void* origSight; err = ACAPI_Sight_SelectSight(nullptr, &origSight); return ; }

3,Part of the code in MyPlugin_Entrance is as follows:

API_AddonType CheckEnvironment (API_EnvirParams* envir) { RSGetIndString (&envir->addOnInfo.name, ID_ADDON_INFO, 1, ACAPI_GetOwnResModule ()); RSGetIndString (&envir->addOnInfo.description, ID_ADDON_INFO, 2, ACAPI_GetOwnResModule ()); return APIAddon_Preload; } // CheckEnvironment // typedef void (*PluginEntry)(); // PluginEntry Do_Export = NULL; // static void LoadAssembly() { std::string assembly_dir = GetExecutablDir(); if (assembly_dir.empty()) return; // std::vector<std::string> assemblys = { "A.dll", "B.dll", "MyPlugin.apx"}; for (size_t i = 0; i < assemblys.size(); i++) { auto assembly = assembly_dir + "/" + assemblys[i]; // auto model = LoadLibrary(assembly.c_str()); //get entry from plugin if (i == assemblys.size() - 1) Do_Export = (PluginEntry)GetProcAddress(model, "Export"); } } GSErrCode ViewNotificationHandlerProc(const API_NotifyViewEventType* viewEvent) { if (Do_Export) { Do_Export(); return NoError; } return NoError; } GSErrCode Initialize (void) { // LoadAssembly(); if (err == NoError) err = ACAPI_Notification_CatchViewEvent(APINotifyView_Opened, API_PublicViewMap, ViewNotificationHandlerProc); return NoError; } // Initialize

The question is that ACAPI_ProjectOperation_Project and ACAPI_Sight_SelectSight return -2130312313 in function Export().

The code outside of ACAPI in the function Export() can execute normally.

I dont know the errors reason. I didnt tried this infrastructure exactly as this.
And it very depend on how A.dll, B.dll work.

Personally, I would have done it differently. All API specific code in real API Addon only.

If you can directly use functionality A.dll, B.dll by GetProcAddress, MyPlugin will not needed.
If the MyPlugin.dll more convenient or needed, It will be like a high level "bridge" between the addon and a third-party dlls functionality and possible memory handling issues. The MyPlugin will not depends on API and not will linked to API.

PS: It's not necessarily good or right, it's just my personal opinion.
