More information is needed.
- What is the base directory of the AppDomains?
- How are you triggering the code in the AppDomain?
- Is the SimplePlugins.DLL also stored in each plugin-subfolder?
- Which assemblies are now loaded in the appdomain? Debug to find out the exact location.
- 'Why doesn't IsSubclassOf find the specified derived type' - does not make sense. IsSubclassOf returns either true or false.

I don't see how that matters. The plugin DLL is in a subfolder of the app's folder.

Calling a method.
maarten_oosterhoff wrote: Is the SimplePlugins.DLL also stored in each plugin-subfolder?
Yes, but that's when it fails. If I don't copy it to that folder, it's fine.

The app is in one domain, and the plugin is in another.

Yeah, I know. My statement indicates that it's returning false.
I just want to know why it makes a difference.

For me, to try to solve your question, it was necessary to ask for some more info. Working with AppDomains and dynamically loading assemblies is tricky, and I need to know what it is exactly that is loaded in the AppDomain, and what the start-up parameters are of said AppDomain (like the base-directory).
My apologies if this was not to your liking.
Good luck solving your problem.

I have an application using System.DirectoryServices.AccountManagement. This exe is in network and almost all user can run the application. For one user, The error is displayed as follows:
Unhanded exception has occured in your application. Could not load file or assembly 'System.DirectoryServices.AccountManagement, Version 3.5.0.0, culture =neutral Public key token = .b77assks778wsdcsd8' or one of its dependencies. The system cannot find the fie specified.
He is having the .Net framework 3.5 and 4. Can some one help me resolving the issue.
Thanks in advance.

That's the wrong public key token. It should be b77a5c561934e089 .
Is that a typo in your question? If not, it sounds like his .NET installation is corrupt.

There is any way for detecting client request is from Virtual Private Network or directly client computer?

You haven't told us anything about your application.

I suspect the IP address, workstation id, user id, logon type, etc. might give you a clue.

Hello Friends,
I'm developing software that uses the DiscUtils to store files in a container such as a virtual disk (VHD), I'm trying to use Ntfs system with VHD, but I've gone through soo many problems because I store a lot of files with varied sizes. The library generates random exceptions. The idea of using that library was to not spend time creating a file system.
The advantage of DiscUtils is that is native C#, so I can use it with Xamarin.
Well, i need an alternative or help to make it work, I need something that can store various files in a container (like a virtual disk). It can be a library that i use with pInvoke , any other library, or a help on how to use the DiscUtils correctly.
I've tried a thousand forks of DiscUtils.
Thank you, I'm desperate to solve this problem.

The only problem with these algorithms is that there is a reconstruction of the file when an entry is removed or added.
What becomes unusable.

Alternatively, you'd use a local database.

Do you recommend any particular compression algorithm?

You'd be using it as a file-archive, so I assume you're more interested in speed than getting a good compression. PkZip has (just like some others) the option "not to compress" anything. Meaning you'd have a (or multiple) dumb container(s) for storing/retrieving files.
You may want to create a test-setup and compare this to a local SQLite database; I'm not sure which of the two would perform better.

There are no "random exceptions"; you need to isolate the problem so you can consider an appropriate action (fix; abandon; whatever).
Work with one "file type" at a time instead of a "lot of files" starting out.
|
|
|
|

This is a backup software so i need it to work with any file type. I've tried to isolate the problem, but it would take a long time to understand the algorithm and fixes it.

That's why they pay you the big bucks.
Seriously, if you have a well-known library that is crashing all the time, then you are probably using it outside the bounds it was intended to be used. I would:
0. RTFM! and check that you are using the APIs correctly.
1. Check for limits on file storage (number of files that may be stored, upper limits on file sizes)
2. Check for limits on container size
3. Check for limits on the file-system containing your container (e.g. FAT32 can only handle files up to 4GB in size)
4. ...
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.
