  • Floating point conversion from Fixed point algorithm

    - by Viks
    Hi, I have an application which is using 24 bit fixed point calculation.I am porting it to a hardware which does support floating point, so for speed optimization I need to convert all fixed point based calculation to floating point based calculation. For this code snippet, It is calculating mantissa for(i=0;i<8207;i++) { // Do n^8/7 calculation and store // it in mantissa and exponent, scaled to // fixed point precision. } So since this calculation, does convert an integer to mantissa and exponent scaled to fixed point precision(23 bit). When I tried converting it to float, by dividing the mantissa part by precision bits and subtracting the exponent part by precision bit, it really does' t work. Please help suggesting a better way of doing it.

  • NSXMLparser errorcode 5

    - by sukitha
    Hi, I'm using Amazon's simpledb in my app. When parsing xml it gives an error with the code 5. ie. NSXMLParserErrorDomain error 5. Sometimes it works fine and without any significant change in the navigation is gives that error. Again it works fine when i restart the app several times without doing any changes to the code or navigation in the system. I cant figure out the reason why this happens. thanks

  • Global name not defined

    - by anteater7171
    I wrote a CPU monitoring program in Python. For some reason sometimes the the program will run without any problem. Then other times the program won't even start because of the following error. Traceback (most recent call last): File "", line 244, in run_nodebug File "C:\Python26\CPUR1.7.pyw", line 601, in app = simpleapp_tk(None) File "C:\Python26\CPUR1.7.pyw", line 26, in init self.initialize() File "C:\Python26\CPUR1.7.pyw", line 107, in initialize self.F() File "C:\Python26\CPUR1.7.pyw", line 517, in F S2 = TL.entryVariableS.get() NameError: global name 'TL' is not defined I can't seem to find the problem, maybe someone more experienced may assist me?

  • FileSystemWatcher running under impersonated user

    - by AdmSteck
    I have an c# winform application that runs under a local account but needs to monitor folders on a domain. I am using slightly modified code from here to copy the files and that works fine. Can similar code be used with the FileSystemWatcher set up impersonation so I can monitor a folder on a domain?

  • SubSonic 2.x now supports TVP's - SqlDbType.Structure / DataTables for SQL Server 2008

    - by ElHaix
    For those interested, I have now modified the SubSonic 2.x code to recognize and support DataTable parameter types. You can read more about SQL Server 2008 features here: http://download.microsoft.com/download/4/9/0/4906f81b-eb1a-49c3-bb05-ff3bcbb5d5ae/SQL%20SERVER%202008-RDBMS/T-SQL%20Enhancements%20with%20SQL%20Server%202008%20-%20Praveen%20Srivatsav.pdf What this enhancement will now allow you to do is to create a partial StoredProcedures.cs class, with a method that overrides the stored procedure wrapper method. A bit about good form: My DAL has no direct table access, and my DB only has execute permissions for that user to my sprocs. As such, SubSonic only generates the AllStructs and StoredProcedures classes. The SPROC: ALTER PROCEDURE [dbo].[testInsertToTestTVP] @UserDetails TestTVP READONLY, @Result INT OUT AS BEGIN SET NOCOUNT ON; SET @Result = -1 --SET IDENTITY_INSERT [dbo].[tbl_TestTVP] ON INSERT INTO [dbo].[tbl_TestTVP] ( [GroupInsertID], [FirstName], [LastName] ) SELECT [GroupInsertID], [FirstName], [LastName] FROM @UserDetails IF @@ROWCOUNT > 0 BEGIN SET @Result = 1 SELECT @Result RETURN @Result END --SET IDENTITY_INSERT [dbo].[tbl_TestTVP] OFF END The TVP: CREATE TYPE [dbo].[TestTVP] AS TABLE( [GroupInsertID] [varchar](50) NOT NULL, [FirstName] [varchar](50) NOT NULL, [LastName] [varchar](50) NOT NULL ) GO The the auto gen tool runs, it creates the following erroneous method: /// <summary> /// Creates an object wrapper for the testInsertToTestTVP Procedure /// </summary> public static StoredProcedure TestInsertToTestTVP(string UserDetails, int? Result) { SubSonic.StoredProcedure sp = new SubSonic.StoredProcedure("testInsertToTestTVP", DataService.GetInstance("MyDAL"), "dbo"); sp.Command.AddParameter("@UserDetails", UserDetails, DbType.AnsiString, null, null); sp.Command.AddOutputParameter("@Result", DbType.Int32, 0, 10); return sp; } It sets UserDetails as type string. As it's good form to have two folders for a SubSonic DAL - Custom and Generated, I created a StoredProcedures.cs partial class in Custom that looks like this: /// <summary> /// Creates an object wrapper for the testInsertToTestTVP Procedure /// </summary> public static StoredProcedure TestInsertToTestTVP(DataTable dt, int? Result) { DataSet ds = new DataSet(); SubSonic.StoredProcedure sp = new SubSonic.StoredProcedure("testInsertToTestTVP", DataService.GetInstance("MyDAL"), "dbo"); // TODO: Modify the SubSonic code base in sp.Command.AddParameter to accept // a parameter type of System.Data.SqlDbType.Structured, as it currently only accepts // System.Data.DbType. //sp.Command.AddParameter("@UserDetails", dt, System.Data.SqlDbType.Structured null, null); sp.Command.AddParameter("@UserDetails", dt, SqlDbType.Structured); sp.Command.AddOutputParameter("@Result", DbType.Int32, 0, 10); return sp; } As you can see, the method signature now contains a DataTable, and with my modification to the SubSonic framework, this now works perfectly. I'm wondering if the SubSonic guys can modify the auto-gen to recognize a TVP in a sproc signature, as to avoid having to re-write the warpper? Does SubSonic 3.x support Structured data types? Also, I'm sure many will be interested in using this code, so where can I upload the new code? Thanks.

  • Java - short and casting

    - by chr1s
    Hi all, I have the following code snippet. public static void main(String[] args) { short a = 4; short b = 5; short c = 5 + 4; short d = a; short e = a + b; // does not compile (expression treated as int) short z = 32767; short z_ = 32768; // does not compile (out of range) test(a); test(7); // does not compile (not applicable for arg int) } public static void test(short x) { } Is the following summary correct (with regard to only the example above using short)? direct initializations without casting is only possible using literals or single variables (as long as the value is in the range of the declared type) if the rhs of an assignment deals with expressions using variables, casting is necessary But why exactly do I need to cast the argument of the second method call taking into account the previous summary?

  • PHP DateTime Regex

    - by CogitoErgoSum
    Hey, long story short I have inherited some terrible code. As a result a string comparison is buggy when comparing dates due to the format of the date. I am trying to convert the date to a valid DateFormat syntax so I can run a proper comparison. These are some samples of the current format: 12/01/10 at 8:00PM 12/31/10 at 12:00PM 12/10/09 at 5:00AM and so forth. I'd like to convert this to a YYYYMMDDHHMM format i.e 201012012000 for comparison purposes. If anyone can give me a quick regex snippet to do this that'd be appreciated as right now i'm hitting a brick wall for a regex. I can do it by exploding the string over several times etc but I'd rather do it in a more efficient manner. Thanks!

  • Gwt-gdata authentication

    - by Raffo
    Hi guys, I'm writing an application with GWT and I found on the internet that there's a library to use easily gdata features. In particular I need to use the integration with Google Calendar. I followed the official guide on gwt-gdata site to do the authentication ( http://code.google.com/p/gwt-gdata/wiki/GettingStarted ) but unfortunately, I got an error. This is the error: 17:59:12.463 [ERROR] [testmappa] Unable to load module entry point class testMappa.client.TestMappa (see associated exception for details) com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.google.accounts is undefined fileName: http://127.0.0.1:8888 lineNumber: 29 stack: ("http://www.google.com/calendar/feeds/")@http://127.0.0.1:8888:29 connect("http://127.0.0.1:8888/TestMappa.html?gwt.codesvr=127.0.0.1:9997","`gL1<a3s4B&Y{(Ci","127.0.0.1:9997","testmappa","2.0")@:0 ((void 0),"testmappa","http://127.0.0.1:8888/testmappa/")@http://127.0.0.1:8888/testmappa/hosted.html?testmappa:264 z()@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:2 (-2)@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:8 at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:195) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.accounts.client.User.login(User.java) at testMappa.client.TestMappa.onModuleLoad(TestMappa.java:68) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.ModuleSpace.onLoad(ModuleSpace.java:369) at com.google.gwt.dev.shell.OophmSessionHandler.loadModule(OophmSessionHandler.java:185) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:380) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:637) I'm not able to understand the reason of this error. My code is simply: String scope = "http://www.google.com/calendar/feeds/"; User.login(scope); And as far as I know it should work as it is. I don't know what to do and I'm here to ask how to solve this problem and if I can directly use gdata native java library, but I believe this other thing is not possible to be done for client-side gwt code (since the code is going to be converted to javascript). Thank you.

  • Input event loop in a console application

    - by Álvaro
    Hi, I'm trying to make a little console application that is able to deal with keystrokes as events. What I need is mostly the ability to get the keystrokes and be able to do something with them without dealing with the typical stdin reading functions. I tried to check the code of programs like mplayer, which implement this (for stopping the play, for example), but I can't get to the core of this with such a big code base. Thanks

  • Simple javascript to mimic jQuery behaviour of using this in events handlers

    - by Marco Demaio
    This is not a question about jQuery, but about how jQuery implements such a behaviour. In jQuery you can do this: $('#some_link_id').click(function() { alert(this.tagName); //displays 'A' }) could someone explain in general terms (no need you to write code) how do they obtain to pass the event's caller html elments (a link in this specific example) into the this keyword? I obviously tried to look 1st in jQuery code, but I could not understand one line. Thanks!

  • How do I use a self encrypting drive?

    - by Unique_Key
    I recently purchased a Micron RealSSD c400 self encrypting drive, and I am having a few issues when trying to get it recognized by my laptop (HP Elitebook 8440p running Windows 7 x64; also tried on a custom-built desktop). When I try to initialize the drive from disk management, I get a CRC error; also, when attempting to partition it from Windows setup, the program can't create the partitions. I also tried with UBCD, nothing. I assume this is due to drive security, but I haven't been able to find much information about this online; do I need a management software or something? I'm completely stumped here. EDIT As requested, when I try partitioning the device from Windows setup I get a 0x80300024 error; when I try initializing it from disk management, I get a "Data error (cyclic redundancy check)" message, and the event log shows the following under System: Source: VDS Basic Provider, message: unexpected failure. error code 490@01010004 (2x) Source: Virtual Disk Service, message: VDS fails to write boot code on a disk during clean operation. Error code: 80070001@02070008 (1x) Source: Disk, message: The device \Device\Harddisk2\DR2 has a bad block (2x) The security logs show nothing related. Also, when attempting to configure it from UBCD (utility: HDAT2), I get an error along the lines of "can't edit partition information" or something to that tune.

  • Zoom in UIImageView without scrollView nor WebView

    Hi, Is there any code example teaching how to zoom in and out in a UIImageView by user taps? I know it is possible to do it with UIScrollView and with UIWebView, but these solutions both need a lot of changes in the code, and I'm working on schedule (bad teachers). I wanted basically an example on how to manipulate directly the UIImageView. Thanks a lot!

  • Make Bluetooth on Android 2.1 discoverable indefinitely

    - by kanov-baekonfat
    Hello all. I'm working on a research project which involves Bluetooth and the Android OS. I need to make Bluetooth discoverable indefinitely in order for the project to continue. The Problem: Android limits discoverability to 300 seconds. I cannot ask the user every 300 seconds to turn discoverability back on as my application is designed to run in the background without disturbing the user. As far as I am aware, there is no way to increase the time though Android's GUI. Some sources have called this a safety feature, others have called this a bug. There may be a bit of truth in both... What I'm Trying / Have Tried: I'm trying to edit a stable release of cyanogenmod to turn the discoverability timer off (it's possible; there's a configuration file that needs to have a single number changed). This isn't working because I'm having verification problems with the resulting package. During the past week, I downloaded the cyanogenmod source code, changed a relevant class in the hope that it would make Bluetooth discoverable indefinitely, and tried to recompile. This did not work because (a) the repo is frequently changed, leading to an unstable code base which fails to compile (OR, it could be that I'm using it incorrectly; just because it looked like it was the code's fault in many instances doesn't mean I should blame it for all the problems I encountered!) and (b) the repo decides to periodically "ignore" me (but not always, as I have gotten the code base before!), replying to my synchronization/connection attempts with: fatal: The remote end hung up unexpectedly As you might imagine, the above two issues are problematic and very frustrating to deal with. More Info: I'm running Android 2.1 via cyanogenmod (v5 I believe). This means the phone is also rooted. I have a developer phone, which means that the bootloader is unlocked. My phone is an HTC Magic (32B). The Big Question: How can I make Bluetooth indefinitely discoverable on Android? Thanks for your time and input. I feel like I'm spinning my tires on this issue and I'd like to move past it.

  • Java library for HTML analysis

    - by Raj
    Hi, (I've seen similar questions, but I think none of them cater to my specific needs, hence...) I would like to know if there is a Java library for analysis of real-world (read: incomplete, ill-formed) HTML. By analysis, I mean things like: figuring out the most prominent color in an HTML chunk changing that color to some other color (hence, has to support modification of the HTML as well) pruning out unwanted tags fixing up the HTML to result in a well formed HTML snippet Parts of the last two are done by libraries such as Jericho, and jTidy. 'Plugins' on top of these would be great. Thanks in advance!

  • Validating String Characters as Numeric w/ Pascal (FastReport 4)

    - by user2525015
    I'm new to Pascal and FastReport. This question can probably be answered without knowledge of FastReport. Pascal is Delphi. FastReport4. I have a text box accepting an 8 character string as input. Each character should be numeric. I'm attempting to validate each character as numeric. I've tried using the val function... Procedure Val(S : String; var R: Real; Code : Integer); begin end; procedure thisinputOnChange(Sender: TfrxComponent); var S : String; error : Integer; R : Real; begin S := thisinput.lines.text; Val (S, R, error); If error > 0 then Button2.enabled := False; end; I got this code online. The explanation says that the function will return an error with a code greater than zero if the character cannot be converted to an integer. Is that explanation correct? Am I misinterpreting? Right now I am trying to set a button's enabled property to false if the validation fails. I might change that to a message. For now, I would like to get it to work by setting the button property. I'm not sure if I should be using the onChange event or another event. I'm also not sure if I need to send the input to the val function in a loop. Like I said, I'm just learning how to use this function. I am able to validate the length. This code works... procedure thisinputOnChange(Sender: TfrxComponent); begin if length(thisinput.lines.text) = 8 then Button2.enabled := True; end; Any suggestions? Should I use the val function or something else? Let me know if I need to provide more info. I might not be able to check back until later, though. Thanks for any help.

    I have some code grabbing a JSON array from my server and initially storing it as a string. This all works fine until I try and deserialize it using google's gson fromJson method. LogCat spits out the error: 04-08 17:46:35.163: ERROR/dalvikvm(401): Can't shrink stack: curFrame is in reserved area (0x41049000 0x410491c4) My code that causes the error is: String[] results = gson.fromJson(returnString, String[].class); Can anyone shed some light on what I am doing wrong? Cheers, Sam

  • Spring MVC annotation config problem

    - by Seth
    I'm trying to improve my spring mvc configuration so as to not require a new config file for every servlet I add, but I'm running into problems. I've tried using this tutorial as a starting point, but I'm running into an issue that I can't figure out. The problem is that when I do a GET to my servlet, I get back a 404 error. Here's my config and a representative java snippet from a Controller: web.xml: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name>SightLogix Coordination System</display-name> <description>SightLogix Coordination System</description> <servlet> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/application-context.xml /WEB-INF/application-security.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <url-pattern>/slcs/*</url-pattern> </servlet-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/application-context.xml /WEB-INF/application-security.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app> application-context.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd" default-init-method="init" default-destroy-method="destroy"> <mvc:annotation-driven /> <context:component-scan base-package="top.level" /> </beans> application-security.xml: <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <http> <intercept-url pattern="/**" access="ROLE_MANAGER" requires-channel="https" /> <http-basic /> </http> <authentication-manager> <authentication-provider user-service-ref="myUserDetailsService"> <password-encoder hash="sha"/> </authentication-provider> </authentication-manager> <beans:bean id="myUserDetailsService" class="path.to.my.UserDetailsServiceImpl"> </beans:bean> </beans:beans> Snippet of a Controller class (one of many, but they all look essentially like this): @Controller @RequestMapping("/foo.xml") public class FooController { @RequestMapping(method=RequestMethod.GET) public void handleGET(HttpServletRequest request, HttpServletResponse response) throws IOException { ...

  • How to stop event bubbling with jquery live?

    - by chobo2
    Hi I am trying to stop some events but stopPropagation does not work with "live" so I am not sure what to do. I found this on their site. Live events do not bubble in the traditional manner and cannot be stopped using stopPropagation or stopImmediatePropagation. For example, take the case of two click events - one bound to "li" and another "li a". Should a click occur on the inner anchor BOTH events will be triggered. This is because when a $("li").bind("click", fn); is bound you're actually saying "Whenever a click event occurs on an LI element - or inside an LI element - trigger this click event." To stop further processing for a live event, fn must return false It says that fn must return false so what I tried to do $('.MoreAppointments').live('click', function(e) { alert("Hi"); return false; }); but that did not work so I am not sure how to make it return false. Update Here is some more information. I have a table cell and I bind a click event to it. $('#CalendarBody .DateBox').click(function(e) { AddApointment(this); }); So the AddApointment just makes some ui dialog box. Now the live code(MoreAppointments) sits in this table cell and is basically an anchor tag. So when I click on the anchor tag it first goes to the above code(addApointment - so runs that event first) runs that but does not launch my dialog box instead it goes straight to the (MoreAppointment) event and runs that code. Once that code has run it launches the dialog box from "addApointment". Update 2 Here is some of the html. I did not copy the whole table since it is kinda big and all the cells repeat itself with the same data. If needed I will post it. <td id="c_12012009" class="DateBox"> <div class="DateLabel"> 1</div> <div class="appointmentContainer"> <a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a> </div> <div class="appointmentOverflowContainer"> <div> <a class="MoreAppointments">+1 More</a></div> </div> </td>

  • Java ExecutorService java heap space ptoblems

    - by Sergey Aganezov jr
    I have a little bit of a problem in a multitasking java department. I have a class, called public class ThreadWorker implements Runnable { //some code in here public void run(){ // invokes some recursion method in the ThreadWorker itself, // which will stop eventually { } all in all, pretty simple "worker" that can work on it's on. To work with threads I'm using public static int THREAD_NUMBER = 4; public static ExecutorServide es = Executors.newFixedThreadPool(THREAD_NUMBER); adding instances of ThreadWroker class happens here: public void recursiveMethod(Arraylist<Integers> elements, MyClass data){ if (elements.size() == 0 && data.qualifies()){ ThreadWorker tw = new ThreadWorker(data); es.execute(tw); return; } for (int i=0; i< elements.size(); i++){ // some code to prevent my problem MyClass data1 = new MyClass(data); MyClass data2 = new MyClass(data); ArrayList<Integer> newElements = (ArrayList<Integer>)elements.clone(); data1.update(elements.get(i)); data2.update(-1 * elements.get(i)); newElements.remove(i); recursiveMethod(newElements, data1); recursiveMethod(newElements, data2); { } and the problem is that the depth of the recursion tree is quite big, so as it's width, so a lot of ThreadWorkers are added to the ExecutorService, so after some time on the big input a get Exception in thread "pool-1-thread-2" java.lang.OutOfMemoryError: Java heap space which is caused, as I think because of a ginormous number of ThreadWorkers i'm adding to ExecutorSirvice to be executed, so it runs out of memory. Every ThreadWorker takes about 40 Mb of RAM for all it needs. Is there a method to get how many threads (instances of classes implementing runnable interface) have been added to ExecutorService? So I can add it in the shown above code (int the " // some code to prevent my problem"), as while ("number of threads in the ExecutorService" > 10){ Thread.sleep(10000); } so I won't go to deep or to broad with my recursion and prevent those exception-throwing situations. Sincerely, Sergey Aganezov jr.

  • subsonic in visual studio design host

    - by csizo
    Hi, I'm facing currently a problem regarding Subsonic configuration. What I want to achieve is using subsonic data access in a System.Web.UI.Design.ControlDesigner class. This class is hosted in Visual Studio Environment and enables design time operations on the attached System.Web.UI.WebControls.Control. The only problem is SubSonic seems always looking for SubSonicSection in the application configuration regardless passing connection string to it. The relevant code snippet: using (SharedDbConnectionScope dbScope = new SharedDbConnectionScope(new SqlDataProvider(), ConnectionString)) { Table1 _table1 = new Select().From<..().Where(...).IsEqualTo(...).ExecuteSingle<...>(); Throws exception on ExecuteSingle() method (configuration section was not found) while using (SharedDbConnectionScope dbScope = new SharedDbConnectionScope(ConnectionString)) { Throws exception on new SharedDbConnectionScope() (configuration section was not found) So the question is: Is there any way to pass the settings runtime to bypass the configuration section lookup as I don't want to add any subsonic specific configuration to devenv.configuration Thanks
