• ASP.NET websites under IIS 7.5 (Windows 7) running extremely slow

  - by emzero

  I've just installed Windows 7 x64 Ultimate on my desktop PC. I installed IIS, Visual Studio 2008, registered ASP.NET, etc. I have this ASP.NET 3.5 website I'm working on running EXTREMELY slow on this new IIS. On STA and PROD servers (Windows 2003 Server) and on my old XP/IIS 5.1 everything runs smoothly. A page which usually takes 1-2 seconds to load is taking 8 seconds!!! I saw this post on IIS forum. It says something about Vista/7 not pooling connections (just to let you know, the website is running locally but it's connecting to a SQL Server 2005 hosted on a remote server). It seems that it takes a while to "start loading" the page... I mean, I click refresh and it stays for several seconds "Waiting for localhost"... Then when it gets response it loads the whole page normally... I don't have a clue how to force Win7/IIS7.5 to pool database connections. EDIT: I've created a new empty ASP.NET web application to see if the problems happens too. The answer is no, it responds fast as it should with an empty default page. Maybe is something related to the DB connection. I will do a further test. It should be a way to fix it... EDIT 2: Debugging the app I noticed that the delay occurs AFTER the execution of .NET code (Page_Load, etc)... so the delay seems to be somewhere when IIS serves the page to the browser.

• Problem interfacing GSM USB modem to Java application

  - by varun

  I am working on an open-source application called FrontlineSMS which can be interfaced with GSM modems to send and receive SMS. The windows installer that is available through their website works fine. Since i wanted to modify it, I got the source code and built the jar and tried to launch it. When I plug in the GSM modem and launch the application, it sometimes detects the GSM device and i am even able to send and receive SMS. Or else 1.) I get the following error- Launching FrontlineSMS for Windows...

• iPhone: Software Development And Distribution

  - by xsl

  I have a few quick questions about the iPhone software development. I did some research about the topic, but there are a few specific things I would like to ask here, because I will have to estimate the cost of the required hardware and software, before I am allowed to buy anything. I never did any Mac development nor have I ever owned an iPhone, so needless to say this is quite hard for me. I will buy an iMac mini with 2 GB RAM for iPhone development. I will have to use it at the same time as my regular PC, but the majority of the time I won't use the Mac at all. Do I have to buy an additional monitor, a mouse and a keyboard or is there a better solution? I will have to port a C library to the iPhone platform and develop an iPhone application that uses the ported library. Do I need anything else than the iPhone SDK to do this? If I use an external library (see above), can I test the application with the integrated emulator, or is it recommend to buy the device? In a later phase of the project I will have to buy an iPhone, but I will have to wait until the iPhone 4 is released here in Europe, because the application requires a camera. In addition to this I will have to send data to a remote webservice. Aside from these two things I don't require any other features. Can I just buy the iPhone online from another country (the iPhones here are sim locked), or should I buy one with a contract? When the application is ready, it will be installed on a few iPhones owned by our customer. Because of security reasons it is crucial that there is no third party involved in this process (i.e. the application should not be distributed on the app store). Is this possible?

• Web application development platform recommendation

  - by TK.Maxi

  Hi all I did a year's worth of Pascal, Visual Basic and C++ 15 years ago, so suffice it to say that I'm a complete n00b & lamer when it comes to this. I really do hope that this question doesn't canned, but if it does, please be so kind as to point me in the direction of where it should be posted. I have an idea, like so many others, for a web app. I don't necessarily have the capital to outsource the development of the app right now, and I probably wouldn't want to, since non-disclosure agreements can be expensive to enforce, especially in this day and age of intercontinental outsourcing. I need the app to be usable on any mobile device (eventually), primarily on the major mobile platforms at first, on the web, (pc/mac/*ix) obviously, on mobile web browsers like opera mobile, etc. I envisage the app interacting with the major social networks like fb, orkut, msn im, twitter, et al in a way where friend's are messaged and/or wall posted, a message is posted to the users wall. Geo-location functionality is a plus, considering the service/app can be location sensitive in two ways, 1, the immediate location of the user, 2. the desired location of the user. I'd like to incorporate OpenID sign on, and the flip-side, the service will require that people (service providers) list their specialities/specialisations/interests/areas of expertise, so that matches to user requests can be made by the service, while users' requests are posted into the web universe. I've probably described a glut of apps out there, but I'd appreciate feedback on the sort of platform that I should look at using, be it hosted on something like Google's app engine, or written in android friendly code, or whatever. I'm a firm believer in herd mentality, especially at the start of a project that I have very little experience in. The more opinions, the merrier! I can't get very much more specific, since that would give the idea away. Thanks for your time and I look forward to hearing from wise and experienced and the fresh and innovative alike. Thanks

• SPP Socket createRfcommSocketToServiceRecord will not connect

  - by philDev

  Hello, I want to use Android 2.1 to connect to an external Bluetooth device, wich is offering an SPP port to me. In this case it is an external GPS unit. When I'm trying to connect I can't connect an established socket while being in the "client" mode. Then if I try to set up a socket (being in the server role), to RECEIVE text from my PC everything works just fine. The Computer can connect as the client to the Socket on the Phone via SPP using the SSP UUID or some random UUID. So the Problem is not that I'm using the wrong UUID. But the other way around (e.g. calling connect on the established client socket) createRfcommSocketToServiceRecord(UUID uuid)) just doesn't work. Sadly I don't have the time to inspect the problem further. It would be greate If somebody could point me the right way. In the following part of the Logfile has to be the Problem. Greets PhilDev P.S. I'm going to be present during the Office hours. Here the log file: 03-21 03:10:52.020: DEBUG/BluetoothSocket.cpp(4643): initSocketFromFdNative 03-21 03:10:52.025: DEBUG/BluetoothSocket(4643): connect 03-21 03:10:52.025: DEBUG/BluetoothSocket(4643): doSdp 03-21 03:10:52.050: DEBUG/ADAPTER(2132): create_device(01:00:00:7F:B5:B3) 03-21 03:10:52.050: DEBUG/ADAPTER(2132): adapter_create_device(01:00:00:7F:B5:B3) 03-21 03:10:52.055: DEBUG/DEVICE(2132): Creating device [address = 01:00:00:7F:B5:B3] /org/bluez/2132/hci0/dev_01_00_00_7F_B5_B3 [name = ] 03-21 03:10:52.055: DEBUG/DEVICE(2132): btd_device_ref(0x10c18): ref=1 03-21 03:10:52.065: INFO/BluetoothEventLoop.cpp(1914): event_filter: Received signal org.bluez.Adapter:DeviceCreated from /org/bluez/2132/hci0 03-21 03:10:52.065: INFO/BluetoothService.cpp(1914): ...

• WPF combobox loses Aero theme when using a style trigger

  - by Greg R

  I am using style triggers to change combo box to texbox if it's readonly, but for some reason when I apply the style, it cause the combobox theme to change from Aero to Windows Classic (the theme I currently have in use on my PC). Can I avoid this somehow? Here is my code: <ComboBox ItemsSource="{Binding Source={StaticResource AllCountries}}" SelectedValue="{Binding OrderInfoVm.BillingCountry}" DisplayMemberPath="Value" SelectedValuePath="Key" IsReadOnly="{Binding ReadOnlyMode}" Style="{StaticResource EditableDropDown}" /> <Style x:Key="EditableDropDown" TargetType="ComboBox"> <Style.Triggers> <Trigger Property="IsReadOnly" Value="True"> <Setter Property="SelectedValuePath" Value="Content" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ComboBox"> <TextBox Text="{TemplateBinding SelectedValue, Converter={StaticResource StringCaseConverter}}" BorderThickness="0" Background="Transparent" FontSize="{TemplateBinding FontSize}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" FontFamily="{TemplateBinding FontFamily}" Width="{TemplateBinding Width}" TextWrapping="Wrap"/> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style>

• Question about using ServiceModelEx's "WCFLogbook" from "Programming WCF Services" book

  - by Bill

  I am attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign). Of course the example application utilizes Juval's ServiceModelEx library and logs faults/errors to a "WCFLogbook" database. Unfortunately, when the sample app faults, I get the following new error: "Cannot open database "WCFLogbook" requested by the login. The login failed. Login failed for user 'Bill-PC\Bill'." I suspect the error occurs as a result of not finding the "WCFLogbook" database, which I believe still needs to be created. Included in the library source directory, there are two files -WCFLogbookDataSet.xsd and WCFLogbook.sql; which neither seem to be referenced anywhere within the library code. This leads me to beleive that the sql and xsd files are there to be used to create the database somehow in SQL. Could someone please advise me if I am going in the correct direction here and if whether these files can be used to create the database (and if so, how)?

• Handling async ASMX web service exceptions

  - by Andy

  Hi, I've developed silverlight client with makes async web services calls to a asmx web service. The problem is, I want to handle exceptions, so far as to be able to tell in the client application whether there was an exception in the webservice (and therefore will be logged local to the webservice) or whether there was a communication problem (i.e. the endpoint for the webservice was wrong). In testing both types of exceptions in my project I get the same generic exception: System.ServiceModel.CommunicationException: The remote server returned an error: NotFound. This exception is amazingly useless when an exception occured in the webservice as it clearly has been found. Is the presence of this generic error to do with security (not being allowed to see true errors)? It can't be the fact that I don't have debug strings as I'm running on a dev PC. Either way, my question is, what's the best way to handle async errors in a commercial silverlight application? Any links or ideas are most welcome! :) Thanks a lot! Andy.

• WSDLs generated by Axis2 services can't be read by SoapUI or WSDL2Java

  - by RJCantrell

  I'm converting some services from Apache SOAP to Axis2, so the Java service classes already exist. I created a new project in Eclipse, imported the source, made sure that the Axis2 project facets were installed, and Axis2 emitter properties are correct. Then, in Eclipse, I selected the service class and chose "Create Web Service," choosing the Axis2 runtime. The service is up and running on my PC, and when I append "?wsdl" to the service's path, I do indeed get a WSDL that I save locally. Attempting to import this into SoapUI to build a client gives the error: ERROR:org.apache.xmlbeans.XmlException: C:\projects\soapUI\Axis2\DALService.wsdl:0: error: src-resolve: type 'SOAPException@http://www.w3.org/2001/XMLSchema' not found. The type it's referring to (SOAPException) is a holdover from the Apache SOAP services, and in the service code, I changed all "import" references in the service code (not the WSDL) from org.apache.soap.SOAPException (the old Apache SOAP package name) to javax.xml.soap.SOAPException (the Axis2 location). The code compiles and works, once I can access it, but I can't access it without generating a client. Any thoughts as to why changing the namespace of an object would keep the generated WSDLs from having the proper namespace references?

• Cannot connect to a SQL Server 2005 Analysis Services cube after installing SQL Server 2008 SP1.

  - by Luc

  I've been developing an application that talks directly to an SSAS 2005 OLAP cube. Note that I also have SQL Server 2008 installed, so the other day I did a Windows Update and decided to include SQL Server 2008 SP1 in my update. After doing that, my SSAS 2005 cube is no longer accessible from my application. I'm able to browse the data just fine within SQL Server 2005 BI Studio Manager, but I'm not able to connect to the cube from my application. Here is my connection string that used to work: Data Source=localhost;Provider=msolap;Initial Catalog=Adventure Works DW Here is the error message I get: Either the user, [Server]/[User], does not have access to the Adventure Works DW database, or the database does not exist.

• nhibernate will not cascade delete childs

  - by marn

  The scenario is as follows, I have 3 objects (i simplified the names) named Parent, parent's child & child's child parent's child is a set in parent, and child's child is a set in child. mapping is as follows (relevant parts) parent <set name="parentset" table="pc-table" lazy="false" fetch="subselect" cascade="all-delete-orphan" inverse="true"> <key column=FK_ID_PC" on-delete="cascade"/> <one-to-many class="parentchild,parentchild-ns"/> </set> parent's child <set name="childset" table="cc-table" lazy="false" fetch="subselect" cascade="all-delete-orphan" inverse="true"> <key column="FK_ID_CC" on-delete="cascade"/> <one-to-many class="childschild,childschild-ns"/> </set> What i want to achieve is that when i delete the parent, there would be a cascade delete all the way trough to child's child. But what currently happens is this. (this is purely for mapping test purposes) getting a parent entity (works fine) IQuery query = session.CreateQuery("from Parent where ID =" + ID); IParent doc = query.UniqueResult<Parent>(); now the delete part session.Delete(doc); transaction.Commit(); After having solved the 'cannot insert null value' error with cascading and inverse i hopes this would now delete everything with this code, but only the parent is being deleted. Did i miss something in my mapping which is likely to be missed? Any hint in the right direction is more than welcome!

• Confusion about Kerberos, delegation and SPNs.

  - by Vilx-

  I'm trying to write a proof-of-concept application that performs Kerberos delegation. I've written all the code, and it seems to working (I'm authenticating fine), but the resulting security context doesn't have the ISC_REQ_DELEGATE flag set. So I'm thinking that maybe one of the endpoints (client or server) is forbidden to delegate. However I'm not authenticating against an SPN. Just one domain user against another domain user. As the SPN for InitializeSecurityContext() I'm passing "[email protected]" (which is the user account under which the server application is running). As I understand, domain users have delegation enabled by default. Anyway, I asked the admin to check, and the "account is sensitive and cannot be delegated" checkbox is off. I know that if my server was running as a NETWORK SERVICE and I used an SPN to connect to it, then I'd need the computer account in AD to have the "Trust computer for delegation" checkbox checked (off by default), but... this is not the case, right? Or is it? Also - when the checkbox in the computer account is set, do the changes take place immediately, or must I reboot the server PC or wait for a while?

• Hot to configure EnterpriseLibrary.Logging to only output message and timestamp

  - by thomas nn

  I am trying to log a simple string to a log file. I only need Category, message and timestamp. Thus I have configured app.config like this: <listeners> <add name="Flat File Destination" fileName="C:\Log\Phoenix.Common.Tests\Debug.log" header="-----------------------------------------------------------------" formatter="Text Formatter" footer="" rollFileExistsBehavior="Increment" rollInterval="Midnight" rollSizeKB="0" timeStampPattern="yyyy-MM-dd" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> </listeners> <formatters> <add name="Text Formatter" template="Category: {category} Message: {message} Timestamp: {timestamp}" type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> </formatters> But I get all kind of additional stuff in my log file: Priority: 50 EventId: 50 Severity: Verbose Title:Testing Log Machine: DK-PC-P4740 App Domain: TestAppDomain: 80803a4f-8e18-47bb-901e-cdac784c8041 ProcessId: 6492 Process Name: C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\QTAgent32.exe How do I avoid this additional stuff? Can someone send me a link to an example that only log the message into the log file? /Thanks

• MVC App Works in Visual Studio, but not IIS7

  - by kesh

  Working on a an ASP.NET MVC Project, and I'm having some difficulties deploying to a shared dev server. Locally, when debugging using the local Visual Studio 2008 server, everything works peachy. However, once deployed, I receive the following error: Parser Error Description: An error occurred during the parsing of a resource required to service this request.

• How to Compile Mod_Python 3.3.1 for Python 2.6 and Apache 2.2 on Windows?

  - by John

  I have no experience compiling code other than using Visual Studio's Build command. I am hoping we can create a step by step guide for compiling mod_python on windows. Please be as descriptive as possible. This is what I've done so far: Download and install python 2.6.2 Download and install apache 2.2.11 Download the most recent source code for mod_python from svn From here I'm lost to what the next step is. I've downloaded Microsoft Visual C++ 2008 Express Edition. As mentioned by Hao I've already tried the tutorial mentioned in that link. Here is the error messages I'm receiving with that tutorial.

• Why is software quality so problematic?

  - by Yuval A

  Even when viewing the subject in the most objective way possible, it is clear that software, as a product, generally suffers from low quality. Take for example a house built from scratch. Usually, the house will function as it is supposed to. It will stand for many years to come, the roof will support heavy weather conditions, the doors and the windows will do their job, the foundations will not collapse even when the house is fully populated. Sure, minor problemsdo occur, like a leaking faucet or a bad paint job, but these are not critical. Software, on the other hand is much more susceptible to suffer from bad quality: unexpected crashes, erroneous behavior, miscellaneous bugs, etc. Sure, there are many software projects and products which show high quality and are very reliable. But lots of software products do not fall in this category. Take into consideration paradigms like TDD which its popularity is on the rise in the past few years. Why is this? Why do people have to fear that their software will not work or crash? (Do you walk into a house fearing its foundations will collapse?) Why is software - subjectively - so full of bugs? Possible reasons: Modern software engineering exists for only a few decades, a small time period compared to other forms of engineering/production. Software is very complicated with layers upon layers of complexity, integrating them all is not trivial. Software development is relatively easy to start with, anyone can write a simple program on his PC, which leads to amateur software leaking into the market. Tight budgets and timeframes do not allow complete and high quality development and extensive testing. How do you explain this issue, and do you see software quality advancing in the near future?

• .NET assembly cache / ngen / jit image warm-up and cool-down behavior

  - by Mike Jiang

  Hi, I have an Input Method (IME) program built with C#.NET 2.0 DLL through C++/CLI. Since an IME is always attaching to another application, the C#.NET DLL seems not able to avoid image address rebasing. Although I have applied ngen to create a native image of that C#.NET 2.0 DLL and installed it into Global Assembly Cache, it didn't improved much, approximately 12 sec. down to 9 sec. on a slow PIII level PC. Therefore I uses a small application, which loads all the components referenced by the C#.NET DLL at the boot up time, to "warm up" the native image of that DLL. It works fine to speed up the loading time to 0.5 sec. However, it only worked for a while. About 30 min. later, it seems to "cool down" again. Is there any way to control the behavior of GAC or native image to be always "hot"? Is this exactly a image address rebasing problem? Thank you for your precious time. Sincerely, Mike
