An unhandled exception of type 'System.StackOverflowException' occurred in System.Data.dll ASP.NET - asp.net
This issue is making me crazy from past two days and I couldn't find any recursion is happening on this method and this issue happening recently, though none of the code has been changed, the following is my code
Calling the procedure:
Dim dssw As New Data.DataSet
dssw = RepSWSC()
The procedure:
Public Function RepSWSC() As Data.DataSet
Dim strConn As String = GetConnString()
Dim patient As String = String.Empty
Dim qid As String = String.Empty
patient = Session("patient")
qid = Session("qid")
Dim con As SqlConnection
If con Is Nothing Then
con = New SqlConnection(strConn)
End If
Try
Dim command As SqlCommand = New SqlCommand("spTestCall", con)
command.CommandType = Data.CommandType.StoredProcedure
Dim parameter As SqlParameter = command.Parameters.Add("#house_id", Data.SqlDbType.Int)
parameter.Value = patient
parameter = command.Parameters.Add("#q_id", Data.SqlDbType.Int)
parameter.Value = qid
If con.State = ConnectionState.Open Then
con.Close()
End If
con.Open()
Dim theDataAdapter As SqlDataAdapter = New SqlDataAdapter(command)
Dim ds As Data.DataSet = New Data.DataSet()
theDataAdapter.Fill(ds)
con.Close()
Return ds
Catch ex As Exception
Throw ex
Finally
con = Nothing
End Try
End Function

Turns out I had to install the ReportViewer runtime exe on the new server.
External Component Thew An Exception
I am having a very weird error on one of my websites. This error only happens on this particular website even though it uses a CMS that is being used by many others. This error also doesn't happen on my test machine, it only happens on the live server. The error is as follows: System.Web.HttpCompileException: External component has thrown an exception. The stack trace is pretty generic: System.Web.HttpParseException (0x80004005): External component has thrown an exception. ---> System.Web.HttpCompileException (0x80004005): External component has thrown an exception. at System.Web.Compilation.AssemblyBuilder.Compile() at System.Web.Compilation.BuildProvidersCompiler.PerformBuild() at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.UI.BaseTemplateParser.GetReferencedType(VirtualPath virtualPath, Boolean allowNoCompile) at System.Web.UI.PageParser.ProcessMainDirectiveAttribute(String deviceName, String name, String value, IDictionary parseData) at System.Web.UI.TemplateParser.ProcessMainDirective(IDictionary mainDirective) at System.Web.UI.TemplateParser.ProcessException(Exception ex) at System.Web.UI.TemplateParser.ParseStringInternal(String text, Encoding fileEncoding) at System.Web.UI.TemplateParser.ParseString(String text, VirtualPath virtualPath, Encoding fileEncoding) at System.Web.UI.TemplateParser.ParseFile(String physicalPath, VirtualPath virtualPath) at System.Web.UI.TemplateParser.ParseInternal() at System.Web.UI.TemplateParser.Parse() at System.Web.Compilation.BaseTemplateBuildProvider.get_CodeCompilerType() at System.Web.Compilation.BuildProvider.GetCompilerTypeFromBuildProvider(BuildProvider buildProvider) at System.Web.Compilation.BuildProvidersCompiler.ProcessBuildProviders() at System.Web.Compilation.BuildProvidersCompiler.PerformBuild() at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVirtualPathObjectFactory(VirtualPath virtualPath, HttpContext context, Boolean allowCrossApp, Boolean throwIfNotFound) at System.Web.Compilation.BuildManager.CreateInstanceFromVirtualPath(VirtualPath virtualPath, Type requiredBaseType, HttpContext context, Boolean allowCrossApp) at System.Web.UI.PageHandlerFactory.GetHandlerHelper(HttpContext context, String requestType, VirtualPath virtualPath, String physicalPath) at System.Web.UI.PageHandlerFactory.GetHandler(HttpContext context, String requestType, String virtualPath, String path) at System.Web.HttpApplication.MaterializeHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) One of the exceptions revealed a little bit more detail: System.ComponentModel.Win32Exception: Access is denied System.Web.HttpParseException (0x80004005): Cannot execute a program.

Does this mean that an Asp.Net exe file is denying requests from my website? This error is random too; sometimes it works and sometimes I get this. Any ideas?
SignalR HTTP 500 when calling server method from client
I'm just getting started with SignalR and have been able to broadcast messages out to all connected clients without any problems. I'd now like to have my client (javascript) join a group and receive only messages for that group. In my hub, I have the following method that adds connections to named groups:
public Task JoinGroup(string groupName)
{
return this.Groups.Add(Context.ConnectionId, groupName);
}
On the client, I have the following JS:
var latLonBounds = new google.maps.LatLngBounds();
var tripIdentifier = '#Model.TripIdentifier';
$(function () {
var hub = $.connection.locationHub;
hub.client.updateLocation = function (coordinates) {
// Implementation omitted
});
latLonBounds.extend(position);
map.fitBounds(latLonBounds);
};
$.connection.hub.logging = true;
$.connection.hub.start().done(function() {
hub.server.joinGroup(tripIdentifier);
});
});
When my page loads,in Chrome, I see an HTTP 500 for the following URL in the console:
http://localhost:49914/signalr/send?transport=serverSentEvents&connectionToken=AQAAANCMnd8BFdERjHoAwE%2FCl%2BsBAAAA8OmZGDrRfEaOjaHahkkarwAAAAACAAAAAAAQZgAAAAEAACAAAADM78kCBInmZa7OROdPoXraiugBXLR5Xu3htxYC2JSnSAAAAAAOgAAAAAIAACAAAAAZwnPx6GMKOiw%2FivqQPlSfCb4WNP342YxvGyBpalmjSDAAAADljl1vg%2F7GYtD3R4AA2A9LXEnNZkyQVQjDUrW7ZVbvfPpWz1GCcOn6aw5yrkrWFrhAAAAAyX5otz0Xhx8tuIRgX2Pr1b9ZWFMvoairvqzns1%2FhjN%2BRhDIuAqAfonTbsZDjkdyDAZXzAKQqwTEKhpa5LYBhKg%3D%3D
In Visual Studio, I see the following stack trace:

If I remove the call to hub.server.joinGroup(tripIdentifier); from my JS, then I don't get the HTTP 500/exception so it seems like this line is the source of the exception.
Any suggestions as to what I can do to get group registration working would be much appreciated.
Thanks!
This is the part of the stack that tells you what's wrong: ---> (Inner Exception #0) System.MissingMethodException: No parameterless constructor defined for this object. at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark) at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark) at System.Activator.CreateInstance(Type type, Boolean nonPublic) at System.Activator.CreateInstance(Type type) at Microsoft.AspNet.SignalR.Hubs.DefaultHubActivator.Create(HubDescriptor descriptor Basically what's that's saying is your hub class doesn't have a parameterless constructor. If you're trying to setup dependency injection for your hubs you appear to have an issue with registering your dependency resolver with SignalR. If you provide more details we can probably help you with getting that fixed as well.
What is the error in this connection string in vb.net?
I have the following connection string
<add name="portal_ConnSql" connectionString="Data Source=GFO-SQL03;Initial Catalog=PortalDB_V2;uid=Portal_Usr;Password=20!!P0rt#!" providerName="System.Data.SqlClient"/>
The code to get the Key :
Public Sub New()
connString = ConfigurationManager.ConnectionStrings("EPER_ConnSql").ToString()
conn = New SqlConnection(connString)
portalConnString = ConfigurationManager.ConnectionStrings("portal_ConnSql").ToString()
portalConn = New SqlConnection(portalConnString)
cmd = New SqlCommand
End Sub

Get
