I develop a plug in dll, i.e. some other process loads my dll, C++ using VS...
I need to add xml parsing to my code and I use libxml2.
I have added that do my dll and now when the application tries to load my dll it fails to load. It is a dependency issue but I can not figure out what all other libs/dlls I need to add to my project.
Any ideas?

I created GUI in C# as gui.dll and create C++/CLI interop interop.dll for C++ project. That means (*.exe call --> interop.dll and interop.dll call --> gui.dll) I test it with C++ console application which is working wintout any problem, because in the end consoleApp.exe and all dlls are in same folder.
What I did:
interop is c++/cli code with reference to C# dll. I created class and export it for use it inside plugin.vst3. C# dll is dynamicaly linked
inside plugin.vst3 project I includeLibrary for interop project to use class and add interop.lib to Linker. interop.dll is dynamicaly linked
What I want:
Now I want use those dlls (gui.dll and interop.dll) inside c++ project as another "dll" myPlugin.vst3 (audio plugin). For those who don't know, audio plugins are located on different location as program which use it. That means, if audio program load plugin, it is different scenario as my consoleApp.exe call dll on same location.
The Problem:
When I run host program which load my vst3, unfortunately vst3 start search for my dlls from AudioHost.exe view not from vst3 view where is my vst3 file located.
For example, if myPlugin.vst3 is inside D:\VstiPlugins\MyTest\, interop.dll is on D:\VstiPlugins\interop.dll and gui.dll next to C:\ProgramFiles\Reaper\Reaper.exe, my plugin is loaded. All files myPlugin.vst3, interop.dll and gui.dll must be on same location D:\VstiPlugins\MyTest.
The questions:
Simple question is "How to load those dlls from vst3" as I describe it in "What I want" and "The Problem"?
What come to mind as firstly was load plugin with code (like LoadLibrary(...)) instead use *.lib. But all examples and solutions, are for dlls which export only C functions and not as my scenario where I use class. Can be dll loaded from code and use class?
Another idea was DLL redirection with manifest file, but there is no documentation for that scenario or I can't find it. And I am not sure if it will be working.
it is possible to load a DLL created in C ++ at compile time. in fact, the goal is to distribute only the .exe without the .dll ?
Thank you .
If you want this to allow distribution of the stand-alone executable as a single file, you could achieve that by using the following method:
Compile the dll you want to include
Serialize it into a binary string and hard code it into your application
When your application starts, open a file and write the DLL string into it using binary mode
Load the DLL using LoadLibrary() and use it
I'm working on a keylogger. Here I found an implementation that loads current keyboard in runtime. The problem is that no keyboard libraries from win8 or win7 are loaded correctly. But I managed to find one US keyboard library that works fine.
So, now, I would like to add that library to resources and to use it when I'm loading keyboard.
My question is, how do I navigate to that resource dll when calling LoadLibrary()?
If you really want an exe instead of installer, you can bundle a dll as resource. ReadResource and write it to file disk(some temp path, such as appdata\local\temp); and then runtime load it, here is the link about runtime load library; Finally you need to delete it.
I have developed a Java applet that loads my C++ dll through the loadLibrary function. From there, my applet calls some native methods that are implemented in the C++ code. I have created an InstallShield installer that puts the C++ dll in the required location on my client computers.
Everything works just fine on my development PC, but when I try testing on a "fresh" client computer that does not have anything but the JRE installed, I am getting an UnsatisfiedLinkError: Can't find dependent libraries. I don't know if there is something else I need to include. I checked using DependencyWalker and below is what I saw.
Is there anything out of the ordinary that a fresh windows install would not include? What else can I do to determine what dependency my dll cannot find on the client?
I need to integrate a 3rd party DLL file with my application, I have only the .DLL and the .pdf documentation of the DLL.
This is the pdf of the dll: http://www.whiteboxrobotics.com/Support/pdf/PC-BOT_dotNet_v1.0_documentation.pdf
I can load the DLL in Visual Studio just by dragging it into the toolbox, BUT, I would like to know how that is done in coding.
Since I only have the DLL, I guess the only option is dynamic loading, using the LoadLibrary() and GetProcAddress().
But it seems to be such a hassle, and I can't figure out how I would load any of the functions which receive some custom (enum) parameters, e.g. in the .pdf the function SendMessage(...) which takes PCBOTEventArgs.messageType as one of the parameters.
Yet loading the DLL through the design view is so simple and extracts the whole DLL.
Why is that?
Is there something else besides using function pointers and GetProcAddress()?
A dotNET = (Mircosoft) .NET Framework is not the same as a "normal" dll, you can't use GetProcAddress and LoadLibrary with .NET dlls
.Net Dlls are normally packed classes, by dragging the dll into your workspace you just import the dlls scope, see for your self in the object browser
to load a .net dll (Assembly) during runtime, for example for a plugin, look here http://support.microsoft.com/kb/837908
3rd Party integration is done using connectivity of what you want to connect for ex you want to add a service to your website, For installing that particular DLL to your website ,first of all read the documentation and connectivity required and than copy paste the DLL files to your projects.
You can make more clear when you can specify the services which want to opt as 3rd party integration
