如何運行DLL項目

Question

這是Oculus的街景項目.....只是我想了解並運行，但我做不到......請幫助我

// dllmain .cpp：定義DLL應用程序的入口點。

包括 「stdafx.h中」

BOOL APIENTRY的DllMain（HMODULE HMODULE， DWORD ul_reason_for_call， LPVOID lpReserved ） { 開關（ul_reason_for_call） { 情況下DLL_PROCESS_ATTACH： 情況DLL_THREAD_ATTACH： 情況DLL_THREAD_DETACH ： case DLL_PROCESS_DETACH： break; } return TRUE; }

包括「stdafx.h中」

你提的問題是很難理解的，因爲它不會對你已經嘗試過什麼什麼真正的東西，什麼是不工作，等

它看起來像你試圖「運行」一個DLL，這是不可能的。一個DLL必須由另一個應用程序加載。所以你會有一個可執行文件來加載這個DLL，並調用它的OVR_Init和OVR_Exit函數。
