loadlibrary

一、背景 在给Adobe Premiere/After Effects等后期制作软件开发第三方插件的时候，我们总希望插件依赖的动态库能够脱离插件的位置，单独存储到另外一个地方。这样一方面可以与其他程序共享这些动态库，还能保证插件安装时非常的清爽。就 Adobe Premiere Pro/After Effects 来说，插件文件是放到 C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore ( Windows 平台)的。这个是 PremierePro 和 AfterEffects 的公共插件目录，二者在启动的时候都会尝试去这个位置加载插件。与此同时，我们希望自己开发的插件所依赖的动态库放到另外的位置，另外也希望插件显示链接的动态库能够尽量少。因为如果是显式链接的话，这些插件依赖的动态库必须和插件保存在同一个位置。不然插件找不到这些依赖文件就会加载失败的。当然，我们也可以在环境变量里面增加一条路径，但是这容易污染环境变量，或者与其他的程序库产生冲突。 LoadLibrary 在这个时候就产生作用了。 LoadLibrary 通过将指定路径的动态库加载到当前的调用进程，然后获取其导出的函数就可以正常使用了。对于像第三方插件这样的应用场景， LoadLibrary 可以说是个不错的实现方式。但是正因此也有个弊端

While loading a dll file, I am getting the following exception: Exception in thread "main" java.lang.UnsatisfiedLinkError: D:\Transliteration\rlpnc-3.1.0-sdk-ia32-w32-msvc80\rlp\bin\ia32-w32-msvc80\btrntjni.dll: The system cannot find message text for message number 0x%1 in the message file for %2 at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(Unknown Source) at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.load0(Unknown Source) at java.lang.System.load(Unknown Source) at com.basistech.util.internal.Native.loadLibrary

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. 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_dzResourceDllLoader.pas .. but it needs other files from the same repository. Yes you can, and you need not

Here's my problem: I would like to create two separate instances of the same DLL. The following doesn't work because Handle1 and Handle2 will get the same address Handle1 := LoadLibrary('mydll.dll'); Handle2 := LoadLibrary('mydll.dll'); The following works, but I have to make a copy of the DLL and rename it to something else (which seems a bit silly) Handle1 := LoadLibrary('mydll.dll'); Handle2 := LoadLibrary('mydll2.dll'); Is there a way to have only one DLL file, but load several instances of it? I don't think that's possible. You'd have to write a .exe which loads the dll. Then you can span

I think I have researched this pretty thoroughly and I have not found an acceptable answer. First the broad strokes: Windows 8.1, Visual Studio 2013. Although, I don't think these are important. Problem as follows. The application I am writing makes use of A.dll. We use a third-party vendor product (a backup program, but again this is not important) that has installed a Context Menu Handler control under HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHandlers. Let's say the path to this is c:\Program Files\Vendor\control.dll. Now, the issue is that when my program opens a file chooser dialog

Is there a platform-independent Java statement to load a native library from a different directory than the Java source code is in? I would like to use something like this: public class HelloWorld { static { System.loadLibrary("../some_project/HelloWorld"); } public static native void print(); } The problem is that System.loadLibrary() doesn't support directory separators in the pathname argument. Also, System.load() unfortunately requires an absolute pathname, which not only means I can't specify a relative directory as above (which I would like to do), but it also requires the argument to

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, which raises an exception. Any insight would be appreciated. The DLL includes testinterfaceload_u and
