  • IIS 7.5 can't access file from managed code

    - by Bob
    I am working on a project that is click-once deployed from an IIS 7.5 web server. After installing the parent application (i.e. setting up the IIS site) I am able to hit the url for the click-once app's config file from a remote box. HOWEVER, when I attempt to do the same thing from my app (and the stub app below), I get a 401 Unauthorized. What is the difference between hitting the URL from IE, and from a .NET app? The file and directory itself have full control granted to everyone on the webserver at the moment, and I am an admin on the box. We are using Windows Authentication with NTLM only. Thanks, -Bob Here is the stub app that produces the 401 - Unauthorized when on the doc.Load() line. I can hit the same URL successfully from IE and open the file... static void Main(string[] args) { Console.WriteLine("Config Test"); string filename = "http://dev-rs/myClient/myClickOnce/myApp.config.xml"; Console.WriteLine(filename); XmlDocument doc = new XmlDocument(); doc.Load(filename); Console.WriteLine("Loaded"); Console.WriteLine("Inner Text : " + doc.InnerText); }

  • Cocos2d shake/accelerometer issue.

    - by Ryan Poolos
    So I a little backstory. I wanted to implement a particle effect and sound effect that both last about 3 sec or so when the user shakes their iDevice. But first issue arrived when the build in UIEvent for shakes refused to work. So I took the advice of a few Cocos veterans to just use some script to get "violent" accelerometer inputs as shakes. Worked great until now. The problem is that if you keep shaking it just stacks the particle and sounds over and over. Now this wouldn't be that big of a deal except it happens even if you are careful to try and not do so. So what I am hoping to do is disable the accelerometer when the particle effect/sound effect start and then reenable it as soon as they finish. Now I don't know if I should do this by schedule, NStimer, or some other function. I am open to ALL suggestions. here is my current "shake" code. - (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration { const float violence = 1; static BOOL beenhere; BOOL shake = FALSE; if (beenhere) return; beenhere = TRUE; if (acceleration.x > violence * 1.5 || acceleration.x < (-1.5* violence)) shake = TRUE; if (acceleration.y > violence * 2 || acceleration.y < (-2 * violence)) shake = TRUE; if (acceleration.z > violence * 3 || acceleration.z < (-3 * violence)) shake = TRUE; if (shake) { id particleSystem = [CCParticleSystemQuad particleWithFile:@"particle.plist"]; [self addChild: particleSystem]; // Super simple Audio playback for sound effects! [[SimpleAudioEngine sharedEngine] playEffect:@"Sound.mp3"]; shake = FALSE; } beenhere = FALSE; }

  • java - coding errors causing endless loop

    - by Daniel Key
    Im attempting to write a program that takes a population's birthrate and deathrate and loops the annual population until it either reaches 0 or doubles. My problem it that it continuously loops an endless amount of illegible numbers and i cant fix it. please help. //***************************************** //This program displays loop statements //Written by: Daniel Kellogg //Last Edited: 9/28/12 //**************************************** import java.util.Scanner; public class Hwk6 { public static void main (String[] args) { int currentYear, currentPopulation; double birthRate, deathRate; Scanner stdin = new Scanner(System.in); System.out.println("\nPopulation Estimator\n"); System.out.println("Enter Year"); currentYear = stdin.nextInt(); System.out.println("Enter Current Population"); currentPopulation = stdin.nextInt(); System.out.println("Enter Birthrate of Population"); birthRate = stdin.nextDouble(); System.out.println("Enter Deathrate of Population"); deathRate = stdin.nextDouble(); int counter = currentPopulation; System.out.println("Population: "); while (currentPopulation != -1) while (counter < currentPopulation * 2) { System.out.print(counter + " "); counter = counter + (int)(counter * birthRate - counter * deathRate); } System.exit(0); } }

  • How to run White + SL4 UATs through TeamCity?

    - by Duncan Bayne
    After experiencing a series of unpleasant issues with TFS, including source code orruption and project management inflexibility, we (meaning the project team of which I'm a part) have decided to move from TFS 2010 to TeamCity + SVN + V1. I've managed to get our MSTest component and unit tests running as part of every build. However, our UATs are failing, and I was hoping for some advice from the TeamCity community as to best practices w.r.t. running web servers and interacting with the desktop. Each of our UAT fixtures starts a web server to host the site, like this: public static void StartWebServer() { var pathToSite = @"C:\projects\myproject\FrontEnd\MyProject.FrontEnd.Web"; var webServer = new Process { StartInfo = new ProcessStartInfo { Arguments = string.Format("/port:9150 /path:\"{0}\"", pathToSite), FileName = @"C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0\WebDev.WebServer40.EXE" } }; webServer.Start(); } Needless to say, this doesn't work when running through TeamCity, as the pathToSite value is different each time. I'm hoping there is a way of determining the path into which the the code is checked out prior to building? That would allow me to point the web server at the right place. The other issue is that our UATs use White to drive the Silverlight UI through an instance of Internet Explorer: _browserWindow = InternetExplorer.Launch("http://localhost:9150/index.html#/Home", "Home - Windows Internet Explorer"); _document = _browserWindow.SilverlightDocument; I've ensured that the TeamCity service is granted the ability to interact with the desktop, and I've set the build agent machine up to log in automatically (an open session is a pre-requisite for White to work properly). Is that all I need to do or are there additional steps required?

  • How do I write test code to exercise a C# generic Pair<TKey, TValue> ?

    - by Scott Davies
    Hi, I am reading through Jon Skeet's "C# in Depth", first edition (which is a great book). I'm in section 3.3.3, page 84, "Implementing Generics". Generics always confuse me, so I wrote some code to exercise the sample. The code provided is: using System; using System.Collections.Generic; public sealed class Pair<TFirst, TSecond> : IEquatable<Pair<TFirst, TSecond>> { private readonly TFirst first; private readonly TSecond second; public Pair(TFirst first, TSecond second) { this.first = first; this.second = second; } ...property getters... public bool Equals(Pair<TFirst, TSecond> other) { if (other == null) { return false; } return EqualityComparer<TFirst>.Default.Equals(this.First, other.First) && EqualityComparer<TSecond>.Default.Equals(this.Second, other.Second); } My code is: class MyClass { public static void Main (string[] args) { // Create new pair. Pair thePair = new Pair(new String("1"), new String("1")); // Compare a new pair to previous pair by generating a second pair. if (thePair.Equals(new Pair(new string("1"), new string("1")))) System.Console.WriteLine("Equal"); else System.Console.WriteLine("Not equal"); } } The compiler complains: "Using the generic type 'ManningListing36.Paie' requires 2 type argument(s) CS0305" What am I doing wrong ? Thanks, Scott

  • I installed XAMPP in a virtual drive and now I can't run its services. Why?

    - by Haris
    Hi, The description is quite long. Please spend some time to read it. ^:)^ I have an old PHP application and I'm trying to test and debug it. Unfortunately, the application uses important data so I can't just click this and that. Now, what I'm trying to do is create a copy of the application in a different computer. From now on, I will call the computer running my original PHP application as 'Computer A' and the computer which I'm going to use to run the copy of the application as 'Computer B'. To prevent missing link problems since the application contains static paths, such in images or tags, I have to copy all files and folder related to my PHP application from Computer A to the same path in Computer B. Unfortunately, Computer B only has drive C while Computer A has drive D and the files of my PHP application is located in 'D:\xampp\htdocs' in Computer A. OK, now I have to create drive D in computer B. At first, I tried to create a second partition in Computer B by using PowerQuest Partition Magic 8, but somehow Partition Magic doesn't run in Computer B. I have tried to reinstall it but it still doesn't run. So, another alternative is to create a virtual drive. That is what I did. I created a virtual drive by running the 'subst' command in Command Prompt. The virtual drive is D and it refers to a directory, which is 'C:\Virtual'. After I have drive D in Computer B, I installed XAMPP there. The installation was successful. Now, I also have 'D:\xampp\htdocs' in Computer B. However, when I ran the Apache, MySQL, or Filezilla service, I receive an error message "Error 3: The system cannot find the file specified.". In Computer B, there is no IIS or process using the port 80. What should I do? Please help me. Many thanks in advance, Haris

  • PHP IP Validation Help

    - by Zubair1
    Hello, I am using this IP Validation Function that i came across while browsing, it has been working well until today i ran into a problem. For some reason the function won't validate this IP as valid: 203.81.192.26 I'm not too great with regular expressions, so would appreciate any help on what could be wrong. If you have another function, i would appreciate if you could post that for me. |--------------------------------------------| The code for the function is below: |--------------------------------------------| public static function validateIpAddress($ip_addr) { global $errors; $preg = '#^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}' .

  • Hybrid EAV/CR model via WCF (and statically-typed language)?

    - by Pat
    Background I'm working on the architecture for a cloud-based LOB application, using Silverlight for the client, WCF, ASP.NET/C# for server and SQL Server for storage. The data model requires some flexibility per user (ability to add custom properties and define validation rules for them, for example), and a hybrid EAV/CR persistence model on the server side will suit nicely. Problem I need an efficient and maintainable technology and approach to handle the transformation from the persisted EAV model to/from WCF (and similarly allow the client to bind to the resulting data - DataGrid is a key UI element)? Admission: I don't yet know enough about WCF to understand if it supports ExpandoObject directly, but I suspect it will. Options I started off looking at WCF RIA services, but quickly discovered they're heavily dependent upon both static type data and compile-time code generation. Neither of these appeal. The options I'm considering include: Using WCF RIA services and pass the data over the network directly in EAV form (i.e. Dictionary), and handle the binding issue purely on the client side (like this) Using a dynamic language (probably IronPython) to handle both ends of the communication, with plumbing to generate the necessary CLR type data on the client to allow binding, and transform to/from EAV form on the server (spam preventer stopped me from posting a URL here, I'll try it in a comment). Dynamic LINQ (CreateClass() and friends), although I'm way out of my depth there and don't know what the limitations on that approach might be yet. I'm interested in comments on these approaches as well as alternative approaches that might solve the problem. Other Notes The Silverlight client will not be the only consumer of the service, making me slightly uncomfortable with option #1 above. While the data model is flexible, it's not expected to be modified heavily. For argument's sake, we could assume that we might have 25 distinct data models active at a given time, with something like 10-20 unique data fields/rules each. Modifications to the data model will happen infrequently (typically when a new user is initially configured).

  • How can I print a web page on a server?

    - by Gavin Schultz
    Suppose I develop a web page using the cool Google visualization API, and it does everything the user wants. They can the parameters, look at the graphs, and print the page to get a reasonable-looking report. All good. Now suppose I want to do the same thing server-side. For example, say we need a set of report generated at a specific time of day, printed to a PDF and emailed to a manager. It's not a user-initiated action, so we don't have a user's browser or their printer. We have a URL that would render the report if we had a browser, and that's it. Is there a good way to do this server-side? Is this just foolish? Has anyone done anything like that before? Do any of the major browsers have APIs that might provide such functionality? Keep in mind too that it's not just static HTML; probably javascript will be running first to shift the DOM around. I know we could implement a whole different reporting engine on the server side to do this, but that will (a) generate reports that look a bit different, and (b) require me to build/maintain two sets of functionality. Instead, I'd be happy if I could just render the page / pages I want in an invisible server-side browser and print it to a PDF (let's mostly ignore that step - I know any number of PDF printer drivers that could do this). I don't really want to do it ugly either - i.e. by starting a browser process and then sending keystrokes directly to the window either - that's just bound to fall apart with a slight nudge. The only related question I found had an answer like that. Any advice appreciated!

  • Multiplication of 2 positive numbers giving a negative result

    - by krandiash
    My program is an implementation of a bloom filter. However, when I'm storing my hash function results in the bit array, the function (of the form f(i) = (a*i + b) % m where a,b,i,m are all positive integers) is giving me a negative result. The problem seems to be in the calculation of a*i which is coming out to be negative. Ignore the print statements in the code; those were for debugging. Basically, the value of temp in this block of code is coming out to be negative and so I'm getting an ArrayOutOfBoundsException. m is the bit array length, z is the number of hash functions being used, S is the set of values which are members of this bloom filter and H stores the values of a and b for the hash functions f1, f2, ..., fz. public static int[] makeBitArray(int m, int z, ArrayList<Integer> S, int[] H) { int[] C = new int[m]; for (int i = 0; i < z; i++) { for (int q = 0; q < S.size() ; q++) { System.out.println(H[2*i]); int temp = S.get(q)*(H[2*i]); System.out.println(temp); System.out.println(S.get(q)); System.out.println(H[2*i + 1]); System.out.println(m); int t = ((H[2*i]*S.get(q)) + H[2*i + 1])%m; System.out.println(t); C[t] = 1; } } return C; } Any help is appreciated.

  • Web API Getting Http 500 error : Issue Solved See Below

    - by Joe Grasso
    Here is my MVC Controller and everything is fine: private UnitOfWork UOW; public InventoryController() { UOW = new UnitOfWork(); } // GET: /Inventory/ public ActionResult Index() { var products = UOW.ProductRepository.GetAll().ToList(); return View(products); } Same method call in API Controller gives me an Http 500 Error: private UnitOfWork _unitOfWork; public TestController() { _unitOfWork = new UnitOfWork(); } public IEnumerable<Product> Get() { var products = _unitOfWork.ProductRepository.GetAll().ToList(); return products; } Debugging shows that indeed there is data being returned in both controllers' UOW calls. I then added a customer configuration in Global: public static void CustomizeConfig(HttpConfiguration config) { config.Formatters.Remove(config.Formatters.XmlFormatter); var json = config.Formatters.JsonFormatter; json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); } I am still receiving an Http 500 in API Controller ONLY and at a loss as to why. Any ideas? UPDATE: It appears using lazy loading caused the problem. When I set the associated properties to NON-VIRTUAL the Test API provided the necessary JSON string. However, whereas before I had the Vendor class included, I only have VendorId. I really wanted to included the associated classes. Any ideas? I know there are alot of smart people out there. Anyone?

  • Invalid method declaration, return type required

    - by Brett Steen
    I am getting an error at public Rectangle(double width, double height){ saying that it's an invalid method declaration, return type required. I'm not sure how to fix it. These are also my instructions for my assignment: Write a super class encapsulating a rectangle. A rectangle has two attributes representing the width and the height of the rectangle. It has methods returning the perimeter and the area of the rectangle. This class has a subclass, encapsulating a parallelepiped, or box. A parallelepiped has a rectangle as its base, and another attribute, its length. It has two methods that calculate and return its area and volume. `public class Rectangle1 { private double width; private double height; public Rectangle1(){ } public Rectangle(double width, double height){ this.width = width; this.height = height; } public double getWidth(){ return width; } public void setWidth(double width) { this.width = width; } public double getHeight(){ return height; } public void setHeight(double height){ this.height = height; } public double getArea(){ return width * height; } public double getPerimeter(){ return 2 * (width + height); } } public class TestRectangle { public static void main(String[] args) { Rectangle1 rectangle = new Rectangle1(2,4); System.out.println("\nA rectangle " + rectangle.toString()); System.out.println("The area is " + rectangle.getArea()); System.out.println("The perimeter is " + rectangle.getPerimeter()); } }`

  • Ruby and duck typing: design by contract impossible?

    - by davetron5000
    Method signature in Java: public List<String> getFilesIn(List<File> directories) similar one in ruby def get_files_in(directories) In the case of Java, the type system gives me information about what the method expects and delivers. In Ruby's case, I have no clue what I'm supposed to pass in, or what I'll expect to receive. In Java, the object must formally implement the interface. In Ruby, the object being passed in must respond to whatever methods are called in the method defined here. This seems highly problematic: Even with 100% accurate, up-to-date documentation, the Ruby code has to essentially expose its implementation, breaking encapsulation. "OO purity" aside, this would seem to be a maintenance nightmare. The Ruby code gives me no clue what's being returned; I would have to essentially experiment, or read the code to find out what methods the returned object would respond to. Not looking to debate static typing vs duck typing, but looking to understand how you maintain a production system where you have almost no ability to design by contract. Update No one has really addressed the exposure of a method's internal implementation via documentation that this approach requires. Since there are no interfaces, if I'm not expecting a particular type, don't I have to itemize every method I might call so that the caller knows what can be passed in? Or is this just an edge case that doesn't really come up?

  • Pass Variable to Java Method from an Ant Target

    - by user200317
    At the moment I have a .properties file to store settings related to the framework. Example: default.auth.url=http://someserver-at008:8080/ default.screenshots=false default.dumpHTML=false And I have written a class to extract those values and here is the method of that class. public static String getResourceAsStream(String defaultProp) { String defaultPropValue = null; //String keys = null; try { InputStream inputStream = SeleniumDefaultProperties.class.getClassLoader().getResourceAsStream(PROP_FILE); Properties properties = new Properties(); //load the input stream using properties. properties.load(inputStream); defaultPropValue = properties.getProperty(defaultProp); }catch (IOException e) { log.error("Something wrong with .properties file, check the location.", e); } return defaultPropValue; } Throughout the application I use method like follows to just exact property needed, public String getBrowserDefaultCommand() { String bcmd = SeleniumDefaultProperties.getResourceAsStream("default.browser.command"); if(bcmd.equals("")) handleMissingConfigProperties(SeleniumDefaultProperties.getResourceAsStream("default.browser.command")); return bcmd; } But I have not decided do a change to this and use ant and pass a parameter instead of using it from .properties file. I was wondering how could I pass a value to a Java Method using ANT. Non of these classes have Main methods and will not have any main. Due to this I was unable to use it as a java system properties. Thanks in advance.

  • How can I search an XML file without a dynamic language?

    - by jeph perro
    Let me try to explain my situation: We are using a CMS which 'bakes' a website, and you publish it to a webserver. The published site contains only static HTML ( or XML ) pages ( generated from the content in the CMS database ). I imported an XML file with the names and phone numbers from the company phone directory. Using only XSLT, can I create a way to search that directory? For example, if my XML file, directory.xml looks like this: <directory> <person> <fname>Ryan</fname> <lname>Purple</lname> <phone>887 778 5544</phone> </person> <person> <fname>Tanya</fname> <lname>Orange</lname> <phone>887 998 5541</phone> </person> <directory> Can I create a way to search for a person with the last name starting with "Pur" ? Can I pass a parameter to the XSLT? Can I search the XML tree to match the string in the parameter?

  • Advantages/Disadvantages of different implementations for Comparing Objects using .NET

    - by Kevin Crowell
    This questions involves 2 different implementations of essentially the same code. First, using delegate to create a Comparison method that can be used as a parameter when sorting a collection of objects: class Foo { public static Comparison<Foo> BarComparison = delegate(Foo foo1, Foo foo2) { return foo1.Bar.CompareTo(foo2.Bar); }; } I use the above when I want to have a way of sorting a collection of Foo objects in a different way than my CompareTo function offers. For example: List<Foo> fooList = new List<Foo>(); fooList.Sort(BarComparison); Second, using IComparer: public class BarComparer : IComparer<Foo> { public int Compare(Foo foo1, Foo foo2) { return foo1.Bar.CompareTo(foo2.Bar); } } I use the above when I want to do a binary search for a Foo object in a collection of Foo objects. For example: BarComparer comparer = new BarComparer(); List<Foo> fooList = new List<Foo>(); Foo foo = new Foo(); int index = fooList.BinarySearch(foo, comparer); My questions are: What are the advantages and disadvantages of each of these implementations? What are some more ways to take advantage of each of these implementations? Is there a way to combine these implementations in such a way that I do not need to duplicate the code? Can I achieve both a binary search and an alternative collection sort using only 1 of these implementations?

  • NPE with logging while launching webstart on jre7 update 40

    - by atulsm
    My application was running fine until I upgraded my jre to 7u40. When my application is initializing, it's doing Logger.getLogger("ClassName"), and I'm getting the following exception. java.lang.ExceptionInInitializerError at java.util.logging.Logger.demandLogger(Unknown Source) at java.util.logging.Logger.getLogger(Unknown Source) at com.company.Application.Applet.<clinit>(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.sun.javaws.Launcher.executeApplication(Unknown Source) at com.sun.javaws.Launcher.executeMainClass(Unknown Source) at com.sun.javaws.Launcher.doLaunchApp(Unknown Source) at com.sun.javaws.Launcher.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.NullPointerException at java.util.logging.Logger.setParent(Unknown Source) at java.util.logging.LogManager$6.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.util.logging.LogManager.doSetParent(Unknown Source) at java.util.logging.LogManager.access$1100(Unknown Source) at java.util.logging.LogManager$LogNode.walkAndSetParent(Unknown Source) at java.util.logging.LogManager$LoggerContext.addLocalLogger(Unknown Source) at java.util.logging.LogManager$LoggerContext.addLocalLogger(Unknown Source) at java.util.logging.LogManager.addLogger(Unknown Source) at java.util.logging.LogManager$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.util.logging.LogManager.<clinit>(Unknown Source) The exception is coming from this line: private static Logger logger = Logger.getLogger(Applet.class.getName()); Could it be because of any sideeffects with fix http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8017174 ? A workaround is to open the java control center and enable logging. This is a concern since by default "Enable Logging" is unchecked. If I select "Enable Logging", the application starts fine.

  • Regex help in java validations

    - by user1697113
    Hi i want to do some validations.I used to put regex in JS but im new to regex in java, so i tried to make up a code on similar lines in java. Here is what i did. 1)Check whether first character in string is alphanumeric. 2)Check whether the string atleast 1 number. so i wrote a code, but it is always returning false.I am not sure if i'm doing this correctly. private static boolean checkEmbeddedPassword(final String field) { boolean returnValue=true; String testpatternAlpha="/^[A-Za-z0-9].+$/"; String testNumber="/[0-9]/"; Pattern pattern=Pattern.compile(testpatternAlpha); Pattern pattern2=Pattern.compile(testNumber); Matcher matcher = pattern.matcher(field); Matcher matcher2 = pattern2.matcher(field); boolean firstChar=matcher.matches(); boolean numberFlag=matcher2.matches(); System.out.println("-----the value of pwd iss-----"+field); System.out.println("---------Regex---------Out--put-----"+firstChar); System.out.println("---------Regex---------Out- for numeral-put-----"+numberFlag); if(firstChar){ returnValue=false; } else if(field.contains(" ")) { System.out.println("-----------cannot have space------"); returnValue=false; } else if(numberFlag) { returnValue=false; } return returnValue; }

  • How to draw a circle in java with a radius and points around the edge

    - by windopal
    Hi, I'm really stuck on how to go about programming this. I need to draw a circle within a JFrame with a radius and points around the circumference. i can mathematically calculate how to find the coordinates of the point around the edge but i cant seem to be able to program the circle. I am currently using a Ellipse2D method but that doesn't seem to work and doesn't return a radius, as under my understanding, it doesn't draw the circle from the center rather from a starting coordinate using a height and width. My current code is on a separate frame but i need to add it to my existing frame. import java.awt.*; import javax.swing.*; import java.awt.geom.*; public class circle extends JFrame { public circle() { super("circle"); setSize(410, 435); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Panel sp = new Panel(); Container content = getContentPane(); content.add(sp); setContentPane(content); setVisible(true); } public static void main (String args[]){ circle sign = new circle(); } } class Panel extends JPanel { public void paintComponent(Graphics comp) { super.paintComponent(comp); Graphics2D comp2D = (Graphics2D) comp; comp2D.setColor(Color.red); Ellipse2D.Float sign1 = new Ellipse2D.Float(0F, 0F, 350F, 350F); comp2D.fill(sign1); } }

  • why DbCommandBuilder (Oracle) produces weird WHERE-clause to UpdateCommand?

    - by matti
    I have a table HolidayHome in oracle db which has unique db index on Id (I haven't specified this in the code in any way for adapter/table/dataset, don't know if i should/can). DbDataAdapter.SelectCommand is like this: SELECT Id, ExtId, Label, Location1, Location2, Location3, Location4, ClassId, X, Y, UseType FROM HolidayHome but UpdateCommand generated by DbCommandBuilder has very weird where clause: UPDATE HOLIDAYHOME SET ID = :p1, EXTID = :p2, LABEL = :p3, LOCATION1 = :p4, LOCATION2 = :p5, LOCATION3 = :p6, LOCATION4 = :p7, CLASSID = :p8, X = :p9, Y = :p10, USETYPE = :p11 WHERE ((ID = :p12) AND ((:p13 = 1 AND EXTID IS NULL) OR (EXTID = :p14)) AND ((:p15 = 1 AND LABEL IS NULL) OR (LABEL = :p16)) AND ((:p17 = 1 AND LOCATION1 IS NULL) OR (LOCATION1 = :p18)) AND ((:p19 = 1 AND LOCATION2 IS NULL) OR (LOCATION2 = :p20)) AND ((:p21 = 1 AND LOCATION3 IS NULL) OR (LOCATION3 = :p22)) AND ((:p23 = 1 AND LOCATION4 IS NULL) OR (LOCATION4 = :p24)) AND (CLASSID = :p25) AND (X = :p26) AND (Y = :p27) AND (USETYPE = :p28)) all these fields that have like: ((:p17 = 1 AND LOCATION1 IS NULL) OR (LOCATION1 = :p18)) are defined in oracle db like this: LOCATION1 VARCHAR2(30) so they allow null values. the code looks like this: static bool CreateInsertUpdateDeleteCmds(DbDataAdapter dataAdapter) { DbCommandBuilder builder = _trgtProvFactory.CreateCommandBuilder(); builder.DataAdapter = dataAdapter; // Get the insert, update and delete commands. dataAdapter.InsertCommand = builder.GetInsertCommand(); dataAdapter.UpdateCommand = builder.GetUpdateCommand(); dataAdapter.DeleteCommand = builder.GetDeleteCommand(); } what to do? The UpdateCommand is utter madness. Thanks & Best Regards: Matti
