I have two 3rd party unmanaged c++ dll and one C++ project which uses these dlls. In my asp.net project i added c++ project as reference but in runtime it fails with that error:
Exception from HRESULT: 0x8007007E
Visual studio puts c++ project's dll into /bin folder auto. Even if i put other dlls into bin folder, it fails.
I am having a silly beginners problem with ASP.Net/Visual Studio 2010. I would like to integrate a number of third party packages into my asp.net MVC app (e.g. CKEditor, TinyMCE.) During the prepwork I sooner or later end with instructions to the order of "copy the package into your project/scripts directory". Sounds easy but I still can't figure out how to do it.
For the time being I trick visual studio into adding the package by adding a blank directory, then go to windows exporer to copy files into the directory, then go back to visual studio to add them one by one. That works for a few javascripts but not for a more complex package. Clearly there must be a better way to add a third-party hierarchical structure to a project, right?

I have a webservice that wraps an unmanaged C++ dll. I'm wondering how I should handle state and multiple connections? I'm thinking that the unmanaged dll will be shared across all connections...is this the case? Note that I am using a shared host so I have limited abilities to modify IIS specifically. If the unmanaged dll is not shared and will have a unique instance for every connection then I have nothing to worry about. If it's the case it's shared then I guess I will have to persist the unmanaged state on a per-connection basis through a DB?
View 1 RepliesIn our WCF service we use a third party product (product C) for querying an external database. We can not change the code in this third party product.
The library is imported for exemple via Declare Function vbPriopti Lib "PRIMCSAM.dll" (ByVal a As String, ByVal b As Integer) As Integer Declare Function vbConnectionClose Lib "PRIMCSAM.dll" () As Integer etc
The problem we face is that the product C keep connections in memory and refuses more connections from the same user/ip address. And their "vbConnectionClose" subroutine does not do proper clean up, something is left in memory and we can therefore not do a new connection.
The only thing to do a new connection is to restart the wcf servcie appliaction on the web server. But I do not want to close my whole app and restart it because of errors in the product C, instead it would be better to just reload the imported dll again?!
What is the easiest way to handle this problem? Restart/close the imported dll? Work with appdomain?

I have created a C++ dll. It works fine and does the job. I have created methods in asp.net that call the methods in C++ dll. DLL path is absolute. It works fine too. I then published the website onto a folder and hosted the website on IIS. I get an error message Exception Details: System.DllNotFoundException: Unable to load DLL 'FilesCreator.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
View 1 RepliesI've inherited a half completed application that seems to use a model that I'm not sure can reliably work.It is a ASP.NET webservice that on each call loads a unmanaged C++ .DLL using
[DllImport ( "kernel32.dll" , EntryPoint = "LoadLibraryA" )]
public static extern int LoadLibrary( string lpLibFileName );.
[DllImport(@"MyUnamanagedDLL.dll")]
public static extern string DoStuff( );
In the unmanaged C++ .dll it is using a singleton to hold state between calls.This is so that it only has to initialise once and load a bunch of slow stuff from disk and database rather than on each webservice call as this is too slow.
So I have an unmanaged C++ dll which I am calling from my ASP.NET application, it has a single entry point and a couple of structures for passing data. If I create a C# console app to call the dll it works fine. If I hook it in to my asp.net app running on my local WinXP machine (IIS 5.1) then it works fine.
When I publish it to our development environement which is running Windows 2003 and IIS 6 then the first 1 or 2 calls works fine but then it simply stops responding. I'm getting no error messages, warnings etc... but I am fast running out of hair!
I've set the virtual directory which runs the asp.net app up inside of its own application pool but this seems to have had no impact.
I am trying to access unmanaged code(C++) dll in my asp.net web application project. I created a class to access library functions to be able to use in my application. The DLL is located in Bin Folder of my project. I was able to work with it fine on my localhost server but when I try it on the server where the application is hosted, it gives me this error:
Security Exception:
Description:
The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission contact your system administrator or change the application's trust level in the configuration file.

View 1 RepliesWhen I turn on Code Coverage in my test settings, on a project that references the Unity DI container I get the following error:
Cannot initialize the ASP.NET project'{Project Name}'.
The event log specifies the following reason:
Could not load file or assembly 'Microsoft.Practices.Unity, Version=2.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. Strong name signature could not be verified.
I have an ASP.NET project under source control (Subversion). For various reasons, I don't want to add the Bin directory or its contents to source control, so I have it svn:ignored. DLLs are loaded into here during a Visual Studio build, and I can start with a clean directory and/or delete all the contents of this directory and still have a successful build.
View 5 RepliesThe server is 64 bit, but the app pool is configured to run as 32 bit. Do i need to publish 64 bit dlls? The rapid fail recovery sometimes recycles the app pool and someone suggested that it may be because i am not using 64 bit dlls. Doesn't sound likely... but you never know.I switched the publish settings to release and any cpu. But it spits out in the bin folder /bin/x64 as well. Do i copy over everything in the bin folder or do i just copy over the x64 dlls?? kinda confused on that. And why are pdb files being spit out with the dlls as well? I thought this was a debug thing only.

We have a plugin system on a WCF service that checks libraries placed in the bin folder for certain assembly level attributes and loads them. This allows customization of certain service calls based on which client is making the call. This works great most of the time. However, sometimes it seems to lose the dll, which causes the service to revert back to the default implementation for every client. The solution so far has been to just move the dll file out of the bin folder, and back in.
View 6 RepliesI created some .net dlls as component to my web application. When I added the reference through VS10, they got into BIN folder. But when I uploaded them on my web host, It doesn't seem to detect them (shows not found error). What additional do I need to do to make them detected?
View 1 RepliesThe way we have to update our site now is to create a copy of the website project locally. Make changes. Then take the dll and any other new files and copy them to the project on the server. Sometimes they want us to work on something they need uploaded right away and other times work on something that needs to be uploaded in the future. So I have to do silly things to give them what they want now and exclude what I am working on for later. What is the best way to resolve this? I just wanna have to upload a piece of the project and certainly not the a whole new dll everytime.

View 4 RepliesI recently noticed that when a dll is replaced at my web site, the site will take a long time to come back, even though the dll is only used by limited pages. I generally have to reset IIS to make the web site come back faster. Is this the normal behavior? or some settings need to be ajusted to avoid this?

How can I get rid of the DLLs?
