从内存中调用DLL函数的源代码，鄙视MemLibLoader不开源

找了个7z的Delphi源码，发现MemLibLoader未开源，其实就是从内存中调用DLL函数，从网上找了些代码拼了一个，以下函数申明方式全部从MemLibLoader照抄 function _LoadLibraryA(FileName:PAnsiChar):DWORD; function _LoadLibraryW(FileName:PWideChar):DWORD; function _LoadLibraryFromResourceA(Instance:DWORD;Name,ResType:PAnsiChar):DWORD; function _LoadLibraryFromResourceW(Instance:DWORD;Name,ResType:PWideChar):DWORD; function _LoadLibraryFromResourceIDA(Instance:DWORD;ResID:Integer;ResType:PAnsiChar):DWORD; function _LoadLibraryFromResourceIDW(Instance:DWORD;ResID:Integer;ResType:PWideChar):DWORD; function _GetProcAddress(hMoudle:DWORD;lpProcName:PAnsiChar):Pointer; stdcall; function _GetProcAddressA(hMoudle:DWORD;lpProcName:PAnsiChar):Pointer; stdcall; function _GetProcAddressW(hMoudle:DWORD;lpProcName:PAnsiChar):Pointer; stdcall; function _LoadLibraryMem(lpMemory:Pointer):DWORD; procedure _FreeLibrary(hMoudle:DWORD); 不过_LoadMemRunExe函数目前无法体会原作者的意图，未加上去。D7下嵌入7z源代码有效，其他环境为测试。
