loadlibrary

问题 I am writing a JNI program and I want to unload the dll after i hava finished using it. What can I do for this purpose? I couldn't find a unloadLibrary() method in the Javadoc. 回答1: There is no direct way of manually unloading your dll. Put simply, your dll will be unloaded when the ClassLoader of the Class that loaded your jni-dll is handled by the garbage collector. 回答2: JVM will manage unloading library so don't bother yourself :) 回答3: Try: FreeLibrary(sdl_library); 来源： https:/

问题 I'm trying to load a library I built with the standalone NDK toolchain. I built libGLmove.so and placed it in libs/armeabi of my Eclipse project However, the call to System.loadLibrary("GLmove") throws an UnsatisfiedLinkError Any ideas as to how to resolve the problem or make Android find my library? How does ndk-build package the library after it builds it? Edit: The exact compile flags are: /Users/thomas/Documents/android-ndk-r5b/toolchains/arm-eabi-4.4.0/prebuilt/darwin-x86/bin/arm-eabi-g+

问题 The LoadLibrary function is returning to me the error code 182. From MSDN: ERROR_INVALID_ORDINAL: "The operating system cannot run %1" Does anyone have a better description of what this error is? 回答1: Very obscure error. The term "ordinal" is however strongly associated with a DLL. A DLL contains a list of exported functions as well as a list of imported functions. Other DLLs that it has a dependency on. These exports and imports usually have a name, but that's not required. They always have

问题 Is it possible to mimic the loadlibrary function? I want to load a library from a BLOB field without first writing it to a temporary file, and I need a solution which is not dependent on specific version of delphi compiler or windows, and does not trigger antivirus software. 回答1: dzlib contains a ready made object for reading a dll from a resource into memory and using it without ever saving it to disc: This is the main file ... http://sourceforge.net/p/dzlib/code/147/tree/dzlib/trunk/src/u

问题 Using Delphi XE. When trying to access a Delphi interface object from a DLL, it fails if I try to do it dynamically versus statically. The interface unit in the dll implements a function to return an instance of the interface. When linked statically, the result is nil when entering the function and everything works. When loading dynamically, the result is non-nil, so when the assignment to result is being done, the IntFCopy code sees it as non-nil and so tries to free it before the assignment

问题 I'm stuck as to why I can't load my dll "interfac" using LoadLibrary. It seems to be failing when loading a dependency but I'm not sure why. Here's the code: AfxMessageBox(L"before load library"); HMODULE interfacDll = LoadLibrary(TEXT("C:\\QA\\Pcdlrn\\Win32\\Release\\INTERFAC.DLL")); if (!interfacDll) DWORD dw = GetLastError(); // returns 0xc1 (193) AfxMessageBox(L"after load library"); And here's the output from gflags (x86)'s loader snaps: 18a0:2a40 @ 06858973 - LdrGetDllHandleEx - ENTER:

问题 i have given a chance to my software user to select dll from openfile dialog.(so my user can download dlls form my website and use it with the main project ). everything is working fine and it can even find that dlls is provided by me or selected an invalid dll.but the problem raises if the user selects a renamed file(eg : apple.txt file renamed to apple.dll ). i typed the code like this try dllHandle := LoadLibrary( pwidechar(openfiledialog1.filename)) ; catch { showmessage if it is not a

问题 I am trying to load a .dll file and have it display a message box when loaded. From my understanding, once a .dll is loaded, it makes a call to dllmain() and switches to the DLL_PROCESS_ATTACH option. I have written the code for both the .dll and the .exe which loads it. The .exe can load it correctly and print out the address in which the dll has been loaded, but I do not see a message box being displayed. I read somewhere on Microsoft.com that the dll enters a "lock" when loaded as to

问题 I have external .DLL file with fast assembler code inside. What is the best way to call functions in this .DLL file to get best performance? 回答1: Your DLL might be in python or c++, whatever , do the same as follow. This is your DLL file in C++. header: extern "C" __declspec(dllexport) int MultiplyByTen(int numberToMultiply); Source code file #include "DynamicDLLToCall.h" int MultiplyByTen(int numberToMultiply) { int returnValue = numberToMultiply * 10; return returnValue; } Take a look at

问题 MSDN says: It must not call the LoadLibrary or LoadLibraryEx function (or a function that calls these functions), because this may create dependency loops in the DLL load order. This can result in a DLL being used before the system has executed its initialization code. I tried to call LoadLibrary from DllMain and nothing happened. The only issue that I see is that loaded DLL will use functions in my DLL before rest of my DllMain executes. Why I must not call LoadLibrary in DllMain? EDIT: OK,
