Running two versions of same Dll parallel in Asp.Net
This error is because may be you have different versions of ddl but there namespace will be same, and you can reference only distinct namespaces in your project. To overcome this, Either create different namespaces for both versions or use strong names for assemblies....
Converting .so file of linux to a .dll file of windows

Reference Two DLLs with the same namespaces and types
Sorry, I had hoped to paste this a comment, but SO prevents me from doing so. As far as I know, VB has not added the C# Aliasing feature, but your assertion that there is no solution in VB.Net is incorrect. Your referenced post from 2011 points you to using...
Breaking as the code execution enters the Dll or Lib space
c++,visual-studio,debugging,dll
So I'm not sure what you want to achieve - you need the program to break without setting breakpoints, or you need just an information into which function/method from the dll program will enter first? I think you can accomplish that with timeline profiling using for example dotTrace: https://www.jetbrains.com/profiler/whatsnew/
Missing DLL even though the directory containing it is in the path
windows,visual-studio-2012,dll,vtk
In VStudio, go to your application project properties, select Debugging, and in the Environment option, add PATH=%path_to_the_folder_where_your_your_dll_is_located%; (I'd suggest using relative paths).

When is it a good idea to make a DLL file
What you are after is code reusability, which is a broader subject than making DLL's, which as @Jodrell said, is created when you compile an assembly. The idea of re using code is something which spans across multiple domains and is not thus strictly related to the .NET platform. You...
The linker link, but the executable ask for another dll
The problem is solved, there was a error in Makefile, in LDFLAGS a "-L/directory/lib", refering to a /lib directory that contain libgtksourceview-3.0.dll.a and libgtksourceview-3.0.la corresponding to the wrong dll.
Function pointer in DLL call - how to handle in C#?
You have to declare a delegate type that matches the native function pointer. It probably should look like this: [UnmanagedFunctionPointer(CallingConvention.Cdecl)] delegate int fct_line_callback(double power, IntPtr userdata); Now you can write the pinvoke declaration: [DllImport("foo.dll", CallingConvention = CallingConvention.Cdecl)] extern static int set_line(int width, fct_line_callback callback); If the callback can only be...
C# Namespace not found for DLL
You're declaring a template, but are not actually instantiating it. C++/CLI templates are just like C++ templates - if you don't instantiate them, they just don't exist outside of the compilation unit. You're looking for generics here (yes, C++/CLI has both templates and generics). And here's how you declare a...
When to free a dll after exporting object
The DLL needs to stay loaded for as long as you're using it, and that includes using the ICar instance. If you free the library and then call a function on that ICar, the function might no longer be there - you've freed it. Saying "I do not really need...
Do I really need __declspec(dllexport) when cross-compiling a DLL with MinGW and wclang?
No, you do not need __declspec(dllexport), when building a DLL with MinGW; (in fact, I frequently omit it myself). The caveat is that, if just one symbol to be included in the DLL is so decorated, then all others you wish to have exported must be likewise decorated, (unless you...
In VC++, is there any way to know the export class of a dll without any header files?
The closest you can get is by reverse engineering (use a debugger) to find the required memory size before calling a constructor, and maybe you could figure out what members are used for (as well as inheritance and other goodies), but you will definitely not have correct names for anything...

Importing C++ custom library functions into C#
std::vector<MyClass>, or indeed any unmanaged C++ class, cannot be used for interop to C#.

Is storing personal libraries as console applications a bad idea?
The immediate benefit is that I can easily implement integration tests within the main application. Why would you want to do that? I don't see that as a benefit at all. Why would you want to deploy your tests when you deploy your production code? And why would having...
Controlling the order of dllmain() calls while being injected to another process
I don't think you can safely call shell functions in DllMain. There is a long list of things you can't do due to the way process initialization is done in Windows.

JNA couldn't find the specified procedure in dll file through java
The problem here is that your DLL is a .Net DLL, which is not a native DLL. JNA only loads and understands native DLLs, that is, DLLs built to function outside the .Net framework. What this means is that you need a different glue between Java and .Net. I have...
How to remove error of incompatible variable types in LoadLibrary() function?
Try HINSTANCE hInstLibrary = LoadLibrary(L"DLL_tut.dll"); or HINSTANCE hInstLibrary = LoadLibrary(_TEXT("DLL_tut.dll")); The thing is that your project is probably compiled with UNICODE macro defined, which causes LoadLibrary to use LoadLibraryW version, which requires Unicode string as a parameter. ...

Translating DLL Call functions from C to Delphi
It would be more useful to see the DLL's actual .h file instead of documentation, as documentation tends to not mention what the calling conventions actually are (and this case is no exception). You are declaring your Delphi functions as stdcall, which may or may not be correct. cdecl is...

The answer was not easy to find. I had tried each DLL that I suspected one by one. The leak was an undeleted array in a C++/CLI wrapper class. Since it is a managed dll, I think, the native "new" calls are traced through msvcr110.dll, and ANTS shows leak in...

Program does not go in order through constructor thus leading to uninitialized variables
I believe 0xc0000409 indicates stack corruption, which could have resulted from various causes beyond just uninitialized variables. Since you note you've had to manually create a DLL header, there's a possibility that it doesn't completely match what the DLL was actually implemented as. Beyond things like parameter count/types and return...
Embarcadero C++Builder: Separate debug/release DLL references possible?

How to run a method on the first call to a .NET dll?
