• SSRS 2005 Set SimplePageHeaders on the report instead of the server?

  - by Adam

  I have one report that does not export to excel friendly from SSRS 2005. I know I can use <Render> <Extension Name="EXCEL" Type="Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer,Microsoft.ReportingServices.ExcelRendering"> <Configuration> <DeviceInfo> <SimplePageHeaders>True</SimplePageHeaders> </DeviceInfo> </Configuration> </Extension> </Render> in the rsreportserver.config, but I am not the only person with reports on this machine. I also found that you can pass &rc:SimplePageHeaders=True in the url to export the report programatically. I tried adding the &rc:SimplePageHeaders=True to the end of the url when navigating to the report manager, but when I select excel from the dropdown and click export the headers are still exported. I even tried setting the rc:Command=Render and rc:Format=EXCEL in the url too without any luck. Is there a way to do what I am trying to do? note: I am wanting to render the report on the built in report manager and use the build in export to excel dropdown, not in an app or website.

• Notification Email Best Practices--From Server Setup to Programming

  - by Andrew Wagner

  All, I'm in the process now of building a SaaS tool that allows network admins to generate notification emails to the members of the end-users of our platform (among many many other things). I'm running into a bit of an "out of my expertise" wall, as I know there are a lot of variables involved with configuring an application that can: Run in a distributed way via load balancing and still-- Leverage a single mail server for sending notification emails Process unsubscribe requests Avoid any ISP blacklisting in the process. If anyone has the time and has done this before, I'd love if you could walk me through the A-Z of best practices both from a configuration perspective and an execution perspective for generating these emails (anything from necessary DNS settings to ideal SMTP setup and configuration) Currently, our application generates email via Google Apps using the PHPMailer class. While this works well, it doesn't queue messages (potential for timeout problems if any of our clients amass a very large list of end-users), and Google limits the amount of allowed generated email messages to 500/day. I know this is a lofty question, but any guidance you could provide would be smashing and a big help as we work through this hurtle in our beta development stage. Thanks!

• Stresstesting ASP.NET/IIS with WCAT

  - by MartinHN

  I'm trying to setup a stress/load test using the WCAT toolkit included in the IIS Resources. Using LogParser, I've processed a UBR file with configuration. It looks something like this: [Configuration] NumClientMachines: 1 # number of distinct client machines to use NumClientThreads: 100 # number of threads per machine AsynchronousWait: TRUE # asynchronous wait for think and delay Duration: 5m # length of experiment (m = minutes, s = seconds) MaxRecvBuffer: 8192K # suggested maximum received buffer ThinkTime: 0s # maximum think-time before next request WarmupTime: 5s # time to warm up before taking statistics CooldownTime: 6s # time to cool down at the end of the experiment [Performance] [Script] SET RequestHeader = "Accept: */*\r\n" APP RequestHeader = "Accept-Language: en-us\r\n" APP RequestHeader = "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705)\r\n" APP RequestHeader = "Host: %HOST%\r\n" NEW TRANSACTION classId = 1 NEW REQUEST HTTP ResponseStatusCode = 200 Weight = 45117 verb = "GET" URL = "http://Url1.com" NEW TRANSACTION classId = 3 NEW REQUEST HTTP ResponseStatusCode = 200 Weight = 13662 verb = "GET" URL = "http://Url1.com/test.aspx" Does it look OK? I execute the controller with this command: wcctl -z StressTest.ubr -a localhost The Client(s) is executed like this: wcclient localhost When the client is executed, I get this error: main client thread Connect Attempt 0 Failed. Error = 10061 Has anyone in this world ever used WCAT?

• Rx Reactive extensions: Unit testing with FromAsyncPattern

  - by Andrew Anderson

  The Reactive Extensions have a sexy little hook to simplify calling async methods: var func = Observable.FromAsyncPattern<InType, OutType>( myWcfService.BeginDoStuff, myWcfService.EndDoStuff); func(inData).ObserveOnDispatcher().Subscribe(x => Foo(x)); I am using this in an WPF project, and it works great at runtime. Unfortunately, when trying to unit test methods that use this technique I am experiencing random failures. ~3 out of every five executions of a test that contain this code fails. Here is a sample test (implemented using a Rhino/unity auto-mocking container): [TestMethod()] public void SomeTest() { // arrange var container = GetAutoMockingContainer(); container.Resolve<IMyWcfServiceClient>() .Expect(x => x.BeginDoStuff(null, null, null)) .IgnoreArguments() .Do( new Func<Specification, AsyncCallback, object, IAsyncResult>((inData, asyncCallback, state) => { return new CompletedAsyncResult(asyncCallback, state); })); container.Resolve<IRepositoryServiceClient>() .Expect(x => x.EndRetrieveAttributeDefinitionsForSorting(null)) .IgnoreArguments() .Do( new Func<IAsyncResult, OutData>((ar) => { return someMockData; })); // act var target = CreateTestSubject(container); target.DoMethodThatInvokesService(); // Run the dispatcher for everything over background priority Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Background, new Action(() => { })); // assert Assert.IsTrue(my operation ran as expected); } The problem that I see is that the code that I specified to run when the async action completed (in this case, Foo(x)), is never called. I can verify this by setting breakpoints in Foo and observing that they are never reached. Further, I can force a long delay after calling DoMethodThatInvokesService (which kicks off the async call), and the code is still never run. I do know that the lines of code invoking the Rx framework were called. Other things I've tried: I have attempted to modify the second last line according to the suggestions here: Reactive Extensions Rx - unit testing something with ObserveOnDispatcher No love. I have added .Take(1) to the Rx code as follows: func(inData).ObserveOnDispatcher().Take(1).Subscribe(x = Foo(x)); This improved my failure rate to something like 1 in 5, but they still occurred. I have rewritten the Rx code to use the plain jane Async pattern. This works, however my developer ego really would love to use Rx instead of boring old begin/end. In the end I do have a work around in hand (i.e. don't use Rx), however I feel that it is not ideal. If anyone has ran into this problem in the past and found a solution, I'd dearly love to hear it.

• Please explain some of Paul Graham's points on LISP

  - by kunjaan

  I need some help understanding some of the points from Paul Graham's article http://www.paulgraham.com/diff.html A new concept of variables. In Lisp, all variables are effectively pointers. Values are what have types, not variables, and assigning or binding variables means copying pointers, not what they point to. A symbol type. Symbols differ from strings in that you can test equality by comparing a pointer. A notation for code using trees of symbols. The whole language always available. There is no real distinction between read-time, compile-time, and runtime. You can compile or run code while reading, read or run code while compiling, and read or compile code at runtime. What do these points mean How are they different in languages like C or Java? Do any other languages other than LISP family languages have any of these constructs now?

• Interfacing Android Nexus One with Arduino + BlueSmirf

  - by efgomez

  I'm a bit new to all of this, so bear with me - I'd really appreciate your help. I am trying to link the Android Nexus One with an arduino (Duemilanove) that is connected to a BlueSmirf. I have a program that is simply outputting the string "Hello Bluetooth" to whatever device the BlueSmirf is connected to. Here is the Arduino program: void setup(){ Serial.begin(115200); int i; } void loop(){Serial.print("Hello Bluetooth!"); delay(1000); } One my computer BT terminal I can see the message and connect no problem. The trouble is with my android code. I can connect to the device with android, but when I look at the log it is not displaying "Hello Bluetooth". Here is the debug log: 04-09 16:27:49.022: ERROR/BTArduino(17288): FireFly-2583 connected 04-09 16:27:49.022: ERROR/BTArduino(17288): STARTING TO CONNECT THE SOCKET 04-09 16:27:55.705: ERROR/BTArduino(17288): Received: 16 04-09 16:27:56.702: ERROR/BTArduino(17288): Received: 1 04-09 16:27:56.712: ERROR/BTArduino(17288): Received: 15 04-09 16:27:57.702: ERROR/BTArduino(17288): Received: 1 04-09 16:27:57.702: ERROR/BTArduino(17288): Received: 15 04-09 16:27:58.704: ERROR/BTArduino(17288): Received: 1 04-09 16:27:58.704: ERROR/BTArduino(17288): Received: 15 ect... Here is the code, I'm trying to put only the relative code but if you need more please let me know: private class ConnectThread extends Thread { private final BluetoothSocket mySocket; private final BluetoothDevice myDevice; public ConnectThread(BluetoothDevice device) { myDevice = device; BluetoothSocket tmp = null; try { tmp = device.createRfcommSocketToServiceRecord(MY_UUID); } catch (IOException e) { Log.e(TAG, "CONNECTION IN THREAD DIDNT WORK"); } mySocket = tmp; } public void run() { Log.e(TAG, "STARTING TO CONNECT THE SOCKET"); InputStream inStream = null; boolean run = false; //...More Connection code here... The more relative code is here: byte[] buffer = new byte[1024]; int bytes; // handle Connection try { inStream = mySocket.getInputStream(); while (run) { try { bytes = inStream.read(buffer); Log.e(TAG, "Received: " + bytes); } catch (IOException e3) { Log.e(TAG, "disconnected"); } } I am reading bytes = inStream.read(buffer). I know bytes is an integer, so I tried sending integers over bluetooth because "bytes" was an integer but it still didn't make sense. It almost appears that is sending incorrect baud rate. Could this be true? Any help would be appreciated. Thank you very much.

• NoSQL vs Ehcache caching advise for speeding up read only mysql Database

  - by paddydub

  I'm building a Route Planner Webapp using Spring/Hibernate/Tomcat and a mysql database, I have a database containing read only data, such as Bus Stop Coordinates, Bus times which is never updated. I'm trying to make the app run faster, each time the application is run it will preform approx 1000 reads to the database to calculate a route. I have setup a Ehcache which greatly improves the read from database times. I'm now setting terracotta + Ehcache distributed caching to share the cache with multiple Tomcat JVMs. This seems a bit complicated. I've tried memcached but it was not performing as fast as ehcache. I'm wondering if a MongoDb or Redis would be better suited. I have no experience with nosql but I would appreciate if anyone has any ideas. What i need is quick access to the read only database.

• psexec failing with return code 122 when used from Windows service

  - by Jeremy McGee

  I've written a WCF service as a wrapper around a C# utility we've written that uses the SysInternals psexec utility to run jobs on a remote system. psexec is invoked from C# with command-line parameters that specify the domain, user and password to use. All works fine when I invoke the C# utility from PowerShell locally. However, when I run the utility from the WCF service we see a return code of 122, which corresponds to (?) "The data area passed to a system call is too small". psexec is running against Windows Server 2008. The credentials I'm passing are local administrator, in the same domain as the machine that hosts the service wrapping the utility.

• Async friendly DispatcherTimer wrapper/subclass

  - by Simon_Weaver

  I have a DispatcherTimer running in my code that fire every 30 seconds to update system status from the server. The timer fires in the client even if I'm debugging my server code so if I've been debugging for 5 minutes I may end up with a dozen timeouts in the client. Finally decided I needed to fix this so looking to make a more async / await friendly DispatcherTimer. Code running in DispatcherTimer must be configurable whether it is reentrant or not (i.e. if the task is already running it should not try to run it again) Should be task based (whether or not this requires I actually expose Task at the root is a gray area) Should be able to run async code and await on tasks to complete Whether it wraps or extends DispatcherTimer probably doesn't really matter but wrapping it may be slightly less ambiguous if you don't know how to use it Possibly expose bindable properties for IsRunning for UI

• Privilege Elevation only when and if required.

  - by Cameron Peters

  My application only very occasionally requires privilege elevation... I need to reference some 3rd party COM components that only work correctly when run as administrator. I would like my application to request privilege elevation only when it needs it... Generally, I don't want my application to run as administrator unless I need to use the 3rd party COM components. I see that CoCreateAsAdmin could potentially solve the problem, but the component author doesn't set up the required registry entries, and I'm not sure how to use CoCreateAsAdmin in C# and in conjuction with Runtime-Callable-Wrapper that is created by tlbimp. Another solution would be to spawn another process, but I have no experience with this yet... I don't want to create a completely separate application... I would be happy to create an assembly that runs in a separated elevated process if someone can show me how to make it work. Thanks...

• Firebird query is crashing with org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544364. reque

  - by user321395

  I am using JdbcTemplate.queryForInt to insert a Row into the DB, and then get the ID back. The Query is "INSERT INTO metadocs(NAME) values (?) RETURNING METADOCID". If I run the statement in Flamerobin, it works fine.

• Jmesa table page navigation

  - by Sara

  I am new to Jmesa and am trying to use it on my jsp page. I use exactly same JSP and controller code as the example on http://code.google.com/p/jmesa/wiki/JSPTagExample . The table shows up and looks fine. The problem is non of the buttons on the toolbar are working. E.g. page navigation arrows, etc. What might be wrong with my code( As I said it is exactly same as the example). Should I add extra code for page navigation? Thanks, Sara. Update: I found out what the problem is, after I enter toolbar buttons it routes to "localhost:8080/portal/projectTag.run?maxRows=4&projectTag_tr_=true&projectTag_p_=1&projectTag_mr_=4" "Instead of "localhost:8080/portal/page/projects/projectTag.run?maxRows=4&projectTag_tr_=true&projectTag_p_=1&projectTag_mr_=4" So it doesn't include the "/page/projects" in the url. How can I add that?

• c# Network Programming - HTTPWebRequest Scraping

  - by masterguru

  Hi, I am building a web scraping application. It should scrape a complex web site with concurrent HttpWebRequests from a single host to a single target web server. The application should run on Windows server 2008. One single HttpWebRequest for data could take from 1 minute to 4 minutes to complete (because of long running db operations) I should have at least 100 parallel requests to the target web server, but i have noticed that when i use more then 2-3 long-running requests i have big performance issues (request timeouts/hanging). How many concurrent requests can i have in this scenario from a single host to a single target web server? can i use Thread Pools in the application to run parallel HttpWebRequests to the server? will i have any issues with the default outbound HTTP connection/requests limits? what about Request timeouts when i reach outbound connection limits? what would be the best setup for my scenario? Any help would be appreciated. Thanks

• CC.NET Dashboard Error: Could not load type 'System.Security.Authentication.ExtendedProtection.Chann

  - by Leslie

  Late last week I upgraded CC.NET locally and on the build server. The build server is still fine, but locally I am now getting the following error: Exception Details: Exortech.NetReflector.NetReflectorTypeLoadException: Unable to load types from assembly System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089: Failed to load 1 of the 3612 types defined in the assembly.

I'm afraid this started after a batch of Windows updates this morning. I had another two updates that won't run, 979909 and 982168 (I had an update that wouldn't run last month). Anyone else having any issues? Thanks!

• Build failing - VS2010 solution on TFS2008

  - by Nick

  I have migrated a VS2008 ASP.NET MVC solution to VS2010/MVC2/.NET 4.0 The solution builds locally and all unit tests pass. Our TFS server is still TFS2008 and I am having problems getting the CI build to pass. The projects all build successfully, the unit tests all run and pass but the Running Tests item fails. I followed this blog post on how to get the build working and I'm almost there. Combing the log file for failures I have found the following: Test Run Completed.

• WiX - create a bootstrap that passes arguments to the msi

  - by Dror Helper

  I need to create a bootstrap for my WiX project I've tried using setupbld.exe but it will only allow me to create an executable that will show my UI or one that will behave as a silent installer but not both. I need to be able to run the resulting executable with argument that will tell it wether or not to show the UI during installation. I've found this post by John Robbins that explains how to re-build the setup.exe stub used in the creation of the bootstrap but I was hoping there is a simpler way to do what I need. Does anyone know of a way to create a bootstrap that I use to run either as a simple (with UI) install or as a silent install.

• Load ActiveX DLL in Internet Explorer with elevated privileges

  - by adum

  I have an ActiveX control that I'm loading with JavaScript in Internet Explorer. It needs to run as medium integrity under UAC in Vista and Win7. This is written in C/C++, compiled in Visual Studio. One way to elevate privileges is to create a broker process that can request a medium integrity level. However, for this project, this is not a practical solution. I really need the ActiveX control itself to run elevated. My question is: what's the easiest way to do this? Can I change the build options on the project to be an exe, and use the COM interprocess connect system to automatically handle the communications, or do I need to be more sophisticated? Do I need to do anything complicated like manually call CreateProcess and make some kind of broker, or can it just work as an ActiveX exe that elevates itself?

• ASP.NET MVC & Silverlight development - on Ubuntu

  - by queen3

  I recently moved my working environment from Windows 7 to Ubuntu, and enjoy this every minute of my working day. My work is currently to develop ASP.NET MVC and Silverlight applications. Thus, important Windows stuff is being still run in VirtualBox (such as IIS, MSSQL, Silverlight 3, and legacy COM stuff). For now, I use Visual Studio under VirtualBox as editor/IDE/debugger. But since I prefer Ubuntu fonts and UI much more I'd like to move at least editor (and better IDE) to native Ubuntu. Things I have already done: I store project files in my home folder and run Visual Studio from \vboxsvr share. With few tricks for ASP.NET it works. I use svn on Ubuntu. I test my ASP.NET MVC site using FireFox/FireBug on Ubuntu. What I need on Ubuntu: SQL client to manage MSSQL. I mostly need querying, but I would miss SQL intellisense support. I enjoy command-line svn a lot, but there're times when it's not enough (e.g. view files / check diffs / selectively commit at the sames time) so I wonder if there're any addons - I don't mean replacement for svn, just addons for rare cases like above. I wonder if there're editors that can provide some C# intellisense. Yes I know about MonoDevelop, but will it provide intellisense without compiling (since I'm going to compile remotely in Win box)? And pretty big topic, what's the best way (editor/IDE) to do "folder-based" development? What I mean: The project is /trunk. Everything is there. I don't want to manually add files to project or like that. The project is the folder and files down there. Main task is to edit files of course. I need a quick way to open / search for files in the project. Like in Resharper, I can click Ctrl-Shift-T (IIRC) and just type file name, a list of matching files in the project folder and below is shown. For example, gedit has file tree browser, but I can't quickly type XYZ to find all XYZ files there; moreover it doesn't automatically switch focus to/from editor; so it's more mouse-oriented; I need 100% keyboard way. I need syntax highlighting for C#/HTML/JS. Most importantly, I need HTML tags autocompletion. I can live without it, but I'll be sorry. I need to run compilation remotely (via ssh I think, invoking NAnt script which does MSBuild) and grab results such as errors and warnings, and I'd prefer to quickly go to error line/file. In short, I need to edit/search/open/svn/compile/run files in some folder. Looks like a case for command-line, but imaging I'm in /trunk and want to open file.cs inside /trunk/foo/bar/boo/far, I wouldn't want to type all this path even with bash autocompletion help. I'd prefer to enter :open file.cs, and maybe then select from list of file.cs and file1.cs. Well, maybe I'll add more soon. Actually, I don't have exact requirements; for example, I don't even know if I need to ask for IDE or editor; or should it have svn support integrated or I need to use it from console; do people work with files from console (search/commit/delete/etc) and open editor from there, or they work from editor/IDE and manage files (search/commit/delete) from there? What's better? I have a feeling that vim might have everything I need. I'd like to confirm that, before I spend a lot of time learning it. No I don't want Emacs. Any other IDE? I like Eclipse, but is it good for such stuff? And after all, do you feel like it's a good way to go? I enjoy Ubuntu, enjoy learning new stuff, and Ubuntu + Windows in VirtualBox actually runs faster than Windows7 on my mahcine, but maybe I need to keep development (editor/files management/etc) in Windows/VirtualBox only, leaving other stuff for Ubuntu?

• SSRS 2008 Report Manager Error

  - by Nick

  I have just installed SQL Server 2008 including Reporting Services on Windows Server 2003. I'm having a problem though accessing the Report Manager. When the Reporting Service is first started I can access it fine but after maybe an hour when I try and access it I get an error saying: Unable to connect to the remote server. The reporting service is still running at this point. I can connect to it through Reporting Services Configuration Manager and clicking on the Web Service URL gives a directory listing (I assume that is correct behaviour). If I stop and start the service through Reporting Services Configuration Manager then I can access Report Manager once again (although in maybe an hour I will get the same error once again). I've installed the latest SP1 service pack. I'm using the same domain account to run all the SQL services. The report server is set to use the default ReportServer virtual directory, is set to IP address All Assigned, TCP Port 80 and no SSL certificate. The report manager is set to use the default Reports virtual directory, IP address All Assigned, TCP Port 80 and no SSL certificates. In the log file I get an error: Unable to connect to remote server HTTP status code 500 An attempt was made to access a socket in a way forbidden by its access permissions. Does anyone have any idea why this is happening? I've searched the net but haven't been able to find a solution.

• Guice and JSF 2

  - by digitaljoel

  I'm trying to use Guice to inject properties of a JSF managed bean. This is all running on Google App Engine (which may or may not be important) I've followed the instructions here: http://code.google.com/docreader/#p=google-guice&s=google-guice&t=GoogleAppEngine One problem is in the first step. I can't subclass the Servlet module and setup my servlet mappings there because Faces is handled by the javax.faces.webapp.FacesServlet which subclasses Servlet, not HttpServlet. So, I tried leaving my servlet configuration in the web.xml file and simply instantiating a new ServletModel() along with my business module when creating the injector in the context listener described in the second step. Having done all that, along with the web.xml configuration, my managed bean isn't getting any properties injected. The method is as follows @ManagedBean @ViewScoped public class ViewTables implements Serializable { private DataService<Table> service; @Inject public void setService( DataService<Table> service ) { this.service = service; } public List<Table> getTables() { return service.getAll(); } } So, I'm wondering if there is a trick to get Guice injecting into a JSF managed bean? I obviously can't use the constructor injection because JSF needs a no-arg constructor to create the bean.

• UITableView backgroundColor always gray on iPad

  - by rjobidon

  Hi, When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light gray background for any color I set including groupTableViewBackgroundColor. Steps to reproduce: Create a new navigation-based project. Open RootViewController.xib and set the table view style to "Grouped". Add this responder to the RootViewController:- (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blackColor]; } Select Simulator SDK 3.2, build and run. You will get a black background (device and simulator). Select your target in the project tree. Click on Project : Upgrade Current Target for iPad. Build and run. You will get a light gray background. Revert the table view style to Plain and you will get a black background. Thanks for your help!

• Android daemon process

  - by J Andy

  Is it possible (without violating any licenses) to write a native C/C++ application on top of the Android OS and make it run as a daemon process? There are already several daemon process' running which one can see with the 'ps' command, the legal part concerns me the most. And also the lack of documentation on how to exactly do this. For the writing part, I guess one could use basic Linux programming concepts, since Android supports at least to some level the standard Posix API. To make it run as the phone boots, some modifications is of course required in init as well. I have no plans to have this app in the Android Market, so installing it manually to the phone is not a problem. As long as it does not require re-compiling the whole OS or kernel. I really appreciate all info on this topic, since there's isn't much available. Thanks.

• How to allow to allow admins to edit my app's config files without UAC elevation?

  - by Justin Grant

  My company produces a cross-platform server application which loads its configuration from user-editable configuration files. On Windows, config file ACLs are locked down by our Setup program to allow reading by all users but restrict editing to Administrators and Local System only. Unfortunately, on Windows Server 2008, even local administrators no longer have admin privileges (because of UAC) unless they're running an elevated app. This has caused complaints from users who cannot use their favorite text editor to open and save config files changes-- they can open the files (since anyone can read) but can't save. Anyone have recommendations for what we can do (if anything) in our app's Setup to make editing easier for admins on Windows Server 2008? Related questions: if a Windows Server 2008 admin wants to edit an admins-only config file, how does he normally do it? Is he forced to use a text editor which is smart enough to auto-elevate when elevation is needed, like Windows Explorer does in response to access denied errors? Does he launch the editor from an elevated command-prompt window? Something else?
