How OS Loaderlock works...

I'm trying to understand in a bit more detail how a OS loaderlock is used in relation to the loading and unloading of DLL's in Windows. I understand that every loaded DLL get notified when a new thread is created/destroyed and or a new DLL is loaded/unloaded. So does that mean that the DllMain function is run inside a lock and no other...

Where to place an unmanaged DLL for use importing into a C# program?

This must be a really stupid question, but I'm still very green when it comes to C#. Anyway, I've got a DLL and I'm importing it with a line like this: [DllImport(@"MyCoolDll")] I've lifted this straight from the demo app provided by the vendor, but it keep complaining that it can't find the DLL. The actual error (from Visual Studio ...

C++/CLI Explicitly Load Managed DLL at runtime (the equivalent of LoadLibrary for Unmanaged)

Problem 1: Is there a way to explicitly load a library at runtime instead of at compile time in C++/CLI. Currently I am using the .NET "Add Reference" at compile time. I would like to explicitly load a managed dll. Is there the .NET equivalent of LoadLibrary? Update: Thanks to Randolpho Assembly::LoadFrom example from MSDN Assembly^ ...

How to implement import lib with simple jmp assembly?

Generated import libraries (the ones used to link a program that will load a dll) AFAICS implements the various calls to the imported functions as assembly jmp statments. This indeed looks like a very optimal solution. It does not require pushing the arguments a second time, neither returning from a call. I want to create my own import...

Trouble registering ChilkatDotNet4.dll to the GAC

EDIT: the GAC issue below may not actually be the culprit. Turns out, even when I create a brand new Console App project and add the .dll directly (so that it lives in the bin), I still can't run it on the sever. Also, I've noted that Console apps are created targeting the .NET 4.0 Client Profile rather than the .NET Framework 4. When...

I have another program (which I do not have the source for, already compiled) that is calling a DLL. I want to swap the DLL out and put my own in its place, to run my own model (inside the DLLs) rather than this other one that comes with the software. I have made DLLs in fortran using the G95 compiler that work declaring them dynamical...
