Configuration :: How To Security Exception Accessing Unmanaged Code DLL
Dec 25, 2010
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.
Exception Details: System.Security.SecurityException:
System.Security.Permissions.SecurityPermission

I have a class that derives from System.Web.UI.Page and have set my pages to derive from this custom page class instead of Page. At runtime, the controls are never initialized and throw a NullReferenceException. I've changed some class names and namespaces in the pasted code to protect the innocent. The only thing that I currently override in my PageBase is OnPreLoad and I do call the base.OnPreLoad. I'll eventually add more functionality to this PageBase but for now all that it has is this:
[Code]....
I've tried putting this into a class library (with System.Web referenced) and I've also tried moving the class into the web application and had the same results either way. As another strange twist, I have another class with derives from PageBase called IndexPageBase and it doesn't have this problem:

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)

I'm having hard time to figure out whats going on with my IIS.My application was running in IIS very well untill I used Visual studio Copy website to update the files in the wwwroot.All of a sudden I got this error.My application works fine from the file system.I tried deleting my application from IIS and uninstalled from control panel and ran the newly built msi/exe but I never got my application back what so ever.This is web.config for reference.I've also tried <trust level="Full"> element but this didn't help.I remember the whole problem started when I was trying to debug the functionality to upload and download files in ASP.Net.

I have an Asp.net web service that I created using Visual Studio 2005. I can acess the web service in my test environment, call methods and return data as expected. If this web service is published to the outside world (Outside of the company firewall), it will return a null why this might be happening? The same code is being used,against the same database. The only difference is that the published website is giving back the null reference exception. If I type in the URL for the web service "https://secure.theSiteGeist.com/wsIndigo.asmx" a list of methods for the web service is displayed in my browser. Yet if I try and call any methods on the web service I get back the null reference exception. Note that the URL I posted above is not the real name of my web service, but is just used for reference sake.

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?

In 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 tried the FreeLibrary method but it did not work, [URL]

I am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.

I'm able to browse my website on my IIS through Localhost. However when I try and access it from my own workstation i cannot connect.
How will overcome this issue? It is down to something on the network, or is it something to do with the IIS?
