I am creating Costume DNN Module but I have "General Exception" happening recently. just want to ask if anyone get this error " General Exception" and how to fix it

That is an easy one, fixed in the next Template release. https://christoctemplate.codeplex.com/discussions/440995
Basically, update your .DNN file to include the proper namespace for your BusinessController class, I left a hardcoded one in there by mistake in one of the templates.

I recently noticed that most of the databases on my SQL Server are getting the Recovery Pending status after running for a few hours (sometimes 6, sometimes more). I can't imagine this being the expected outcome, so I decided to post about it here.
I opened the Event Log viewer and decided to find some more info about what's going on. It seems that all my databases are "Starting up" every few minutes or so (as cam be seen here). Some of them get started multiple times in a row. Is that supposed to work like that?
After scrolling a bit more, I found this warning from one of my IIS websites:

Custom event details:
Seems like there's something wrong with SignalR, so it shouldn't have any direct relation with the database, but there aren't any other errors/warnings there.
Am I missing something here?
Thank you!
Do you have "auto close" enabled on the database?
Best practice is to have it OFF
ALTER DATABASE <mydb> SET AUTO_CLOSE OFF
I would also check AUTO_SHRINK while I was there
I have a C++/CLI DLL that needs to run in the context of an ASP.NET WebApi action.
The action is affected by an ActionFilter that uses log4net's LogicalThreadContext to set a property containing a request ID; this works nicely to write the request ID into the log entries.
The problem is that ASP.NET seems to be creating an appdomain when it's time to load the class from the C++/CLI dll. (I can't seem to find any documentation on how that works; I'd love to find some.) When the appdomain plumbing tries to deserialize everything, it chokes because it can't find log4net.dll (see stack trace below).
Fusion logs show that it's looking in C:\Windows\System32\inetsrv, which is incorrect... I would expect it to look in the probing path or along the %PATH% environment variable.
A few data points:
log4net.dll is available in the web app's bin directory and works fine for everything else I'm using it for.
The C++/CLI code has no dependencies on log4net.
If I comment out my calls to log4net.LogicalThreadContext.Properties[...], everything works fine.
If I copy log4net.dll from my bin folder to C:\Windows\system32\inetsrv, everything works fine.
The web.config file specifies the probing path with a <probing privatePath="bin"/> element.
My Application_Start method in global.asax.cs prepends the web app's bin directory to the %PATH% environment variable:
var currentPathEnvVar = Environment.GetEnvironmentVariable("PATH");
var binPath = Path.Combine(Server.MapPath("~") ?? String.Empty, "bin");
_log.DebugFormat("Prepending paths to PATH: [{0}]", binPath);
Environment.SetEnvironmentVariable("PATH", String.Concat(binPath, Path.PathSeparator, currentPathEnvVar));
The log shows that the %PATH% is getting prepended correctly:
2015-06-05 17:07:48,816 1 DEBUG MyNamespace.WebApiApplication (null) Prepending paths to PATH: [C:\Program Files\MyCompany\MyApp\web\bin]
So how do I get the appdomain that ASP.NET creates to look in the right place to load assemblies?
Thanks.
Here's the stack trace that gets logged when all this goes down.

This helped me to resolve similar issue:
https://blogs.msdn.microsoft.com/jorman/2007/08/31/loading-c-assemblies-in-asp-net/
Faced option 2.a and proposed solution worked fine:
protected void Application_Start(object sender, EventArgs e){
String _path = String.Concat(System.Environment.GetEnvironmentVariable("PATH"), ";",
System.AppDomain.CurrentDomain.RelativeSearchPath);
System.Environment.SetEnvironmentVariable("PATH", _path, EnvironmentVariableTarget.Process); }
I'm using crank to load test my signalr application. The command that I'm using is as follows
crank /NumClients:100 /Url:http://localhost:29573/TestConnection /BatchSize:10
I'm getting an exception in my powershell window as follows...

I do have the sample application: SignalR.LoadTestHarness running at localhost:29573. This is the same application that is found in the SignalR source code samples.
What am I doing wrong?
You did not provide the ControllerUrl parameter and as a result crank is trying to create a hub connection with null Url which results in throwing a NullReferenceException on this line.
I'm creating an app "plugin" dll that loads at run-time for my Mono for Android App and starts a new Activity. (the app will be installed ad-hoc - so no comments on downloading executable code)
I'm coming from Obj-C on iOS - where you can include .nibs and ViewControllers in a library.
I can have the main Android app and the loaded dll both reference another common dll, and load objects just fine.
The following works:
var test = plugin.CreateInstance("Test.Satellite.testClass");
MethodInfo getString = test.GetType().GetMethod("getString");
MethodInfo tryPatient = test.GetType().GetMethod("tryPatient");
Where
public class testClass
{
public string getString ()
{
return "This was read from the object";
}
public string tryPatient ()
{
Patient p = new Patient();
p.Name = "This was created from the Core/Common DLL";
return p.Name;
}
}
However, when I try to load an Activity (either through CreateInstance or Intent/StartActivity) it gives the following exception:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Exception: test.satellite.RootActivity

What I can read from that is that the Dalvik can't find the class test.satellite.RootActivity - but it found test.satellite.testClass just fine...?
Any help would be appreciated.
It looks like you are inconsistent about the casing of packages. Might that be the problem?
"Test.Satellite.testClass" -- works
"test.satellite.RootActivity" -- doesn't work

Is this an inner exception that you are seeing?
regarding ToString():
If there is no error message or if it is an empty string (""), then no error message is returned. The name of the inner exception and the stack trace are returned only if they are not a null reference
