  • MS SQL and .NET Typed Dataset AllowDBNull Metadata

    - by Christian Pena
    Good afternoon, I am generating a typed dataset from a stored procedure. The stored procedure may contain something like: select t1.colA, t2.colA AS t2colA from t1 inner join t2 on t1.key = t2.key When I generate the typed dataset, the dataset knows whether t1.colA allows NULLs, but it always puts FALSE in AllowDBNull for t2.colA even if t2.colA allows NULL. Is this because the column is aliased? Is there any way, from SQL, to hint to VS that the column allows NULL? We currently have to go in and update the column's AllowDBNull if we regenerate the table. Thanks in advance. Christian

  • PhysX Question about Raycasting - Setting the shape masks

    - by sweet tv
    I am trying to make the raycast give me the distance of the terrain and nothing else. But I'm not sure how to use the group Mask Filter. virtual NxShape* raycastClosestShape (const NxRay& worldRay, NxShapesType shapeType, NxRaycastHit& hit, NxU32 groups=0xffffffff, NxReal maxDist=NX_MAX_F32, NxU32 hintFlags=0xffffffff, const NxGroupsMask* groupsMask=NULL, NxShape** cache=NULL) const = 0; \param[in] groups Mask used to filter shape objects. Let's say my terrain is set in group 1. How would I use the function above?

  • VerifyError When Running jUnit Test on Android 1.6

    - by DKnowles
    Here's what I'm trying to run on Android 1.6: package com.healthlogger.test; public class AllTests extends TestSuite { public static Test suite() { return new TestSuiteBuilder(AllTests.class).includeAllPackagesUnderHere().build(); } } and: package com.healthlogger.test; public class RecordTest extends AndroidTestCase { /** * Ensures that the constructor will not take a null data tag. */ @Test(expected=AssertionFailedError.class) public void testNullDataTagInConstructor() { Record r = new Record(null, Calendar.getInstance(), "Data"); fail("Failed to catch null data tag."); } } The main project is HealthLogger. These are run from a separate test project (HealthLoggerTest). HealthLogger and jUnit4 are in HealthLoggerTest's build path. jUnit4 is also in HealthLogger's build path. The class "Record" is located in com.healthlogger. Commenting out the "@Test..." and "Record r..." lines allows this test to run. When they are uncommented, I get a VerifyError exception. I am severely blocked by this; why is it happening? EDIT: some info from logcat after the crash: E/AndroidRuntime( 3723): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 3723): java.lang.VerifyError: com.healthlogger.test.RecordTest E/AndroidRuntime( 3723): at java.lang.Class.getDeclaredConstructors(Native Method) E/AndroidRuntime( 3723): at java.lang.Class.getConstructors(Class.java:507) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.hasValidConstructor(TestGrouping.java:226) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.apply(TestGrouping.java:215) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.apply(TestGrouping.java:211) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.select(TestGrouping.java:170) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.selectTestClasses(TestGrouping.java:160) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.testCaseClassesInPackage(TestGrouping.java:154) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.addPackagesRecursive(TestGrouping.java:115) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestSuiteBuilder.includePackages(TestSuiteBuilder.java:103) E/AndroidRuntime( 3723): at android.test.InstrumentationTestRunner.onCreate(InstrumentationTestRunner.java:321) E/AndroidRuntime( 3723): at android.app.ActivityThread.handleBindApplication(ActivityThread.java:3848) E/AndroidRuntime( 3723): at android.app.ActivityThread.access$2800(ActivityThread.java:116) E/AndroidRuntime( 3723): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1831) E/AndroidRuntime( 3723): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 3723): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 3723): at android.app.ActivityThread.main(ActivityThread.java:4203) E/AndroidRuntime( 3723): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 3723): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 3723): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) E/AndroidRuntime( 3723): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) E/AndroidRuntime( 3723): at dalvik.system.NativeStart.main(Native Method)

  • NHibernate (3.1.0.4000) NullReferenceException using Query<> and NHibernate Facility

    - by TigerShark
    I have a problem with NHibernate, I can't seem to find any solution for. In my project I have a simple entity (Batch), but whenever I try and run the following test, I get an exception. I've triede a couple of different ways to perform a similar query, but almost identical exception for all (it differs in which LINQ method being executed). The first test: [Test] public void QueryLatestBatch() { using (var session = SessionManager.OpenSession()) { var batch = session.Query<Batch>() .FirstOrDefault(); Assert.That(batch, Is.Not.Null); } } The exception: System.NullReferenceException : Object reference not set to an instance of an object. at NHibernate.Linq.NhQueryProvider.PrepareQuery(Expression expression, ref IQuery query, ref NhLinqExpression nhQuery) at NHibernate.Linq.NhQueryProvider.Execute(Expression expression) at System.Linq.Queryable.FirstOrDefault(IQueryable`1 source) The second test: [Test] public void QueryLatestBatch2() { using (var session = SessionManager.OpenSession()) { var batch = session.Query<Batch>() .OrderBy(x => x.Executed) .Take(1) .SingleOrDefault(); Assert.That(batch, Is.Not.Null); } } The exception: System.NullReferenceException : Object reference not set to an instance of an object. at NHibernate.Linq.NhQueryProvider.PrepareQuery(Expression expression, ref IQuery query, ref NhLinqExpression nhQuery) at NHibernate.Linq.NhQueryProvider.Execute(Expression expression) at System.Linq.Queryable.SingleOrDefault(IQueryable`1 source) However, this one is passing (using QueryOver<): [Test] public void QueryOverLatestBatch() { using (var session = SessionManager.OpenSession()) { var batch = session.QueryOver<Batch>() .OrderBy(x => x.Executed).Asc .Take(1) .SingleOrDefault(); Assert.That(batch, Is.Not.Null); Assert.That(batch.Executed, Is.LessThan(DateTime.Now)); } } Using the QueryOver< API is not bad at all, but I'm just kind of baffled that the Query< API isn't working, which is kind of sad, since the First() operation is very concise, and our developers really enjoy LINQ. I really hope there is a solution to this, as it seems strange if these methods are failing such a simple test. EDIT I'm using Oracle 11g, my mappings are done with FluentNHibernate registered through Castle Windsor with the NHibernate Facility. As I wrote, the odd thing is that the query works perfectly with the QueryOver< API, but not through LINQ.

  • Patterns for simulating optional "out" parameters in C#?

    - by Jesse McGrew
    I'm translating an API from C to C#, and one of the functions allocates a number of related objects, some of which are optional. The C version accepts several pointer parameters which are used to return integer handles to the objects, and the caller can pass NULL for some of the pointers to avoid allocating those objects: void initialize(int *mainObjPtr, int *subObjPtr, int *anotherSubObjPtr); initialize(&mainObj, &subObj, NULL); For the C# version, the obvious translation would use out parameters instead of pointers: public static void Initialize(out int mainObj, out int subObj, out int anotherSubObj); ... but this leaves no way to indicate which objects are unwanted. Are there any well-known examples of C# APIs doing something similar that I could imitate? If not, any suggestions?

  • Managing of shared resources between classes?

    - by Axarydax
    Imagine that I have a several Viewer component that are used for displaying text and they have few modes that user can switch (different font presets for viewing text/binary/hex). What would be the best approach for managing shared objects - for example fonts, find dialog, etc? I figured that static class with lazily initialized objects would be OK, but this might be the wrong idea. static class ViewerStatic { private static Font monospaceFont; public static Font MonospaceFont { get { if (monospaceFont == null) //TODO read font settings from configuration monospaceFont = new Font(FontFamily.GenericMonospace, 9, FontStyle.Bold); return monospaceFont; } } private static Font sansFont; public static Font SansFont { get { if (sansFont == null) //TODO read font settings from configuration sansFont = new Font(FontFamily.GenericSansSerif, 9, FontStyle.Bold); return sansFont; } } }

  • Problem updating blog with hibernate?

    - by johnsmith51
    hi, i am having problem updating a blob with hibernate. my model have these getters/setters for hibernate, i.e. internally i deal with byte[] so any getter/setter convert the byte[] to blog. I can create an initial object without problem, but if I try to change the content of the blob, the database column is not updated. I do not get any error message, everything looks fine, except that the database is not updated. /** do not use, for hibernate only */ public Blob getLogoBinaryBlob() { if(logoBinary == null){ return null; } return Hibernate.createBlob(logoBinary); } /** do not use, for hibernate only */ public void setLogoBinaryBlob(Blob logoBinaryBlob) { ByteArrayOutputStream baos = new ByteArrayOutputStream(); try { logoBinary = toByteArrayImpl(logoBinaryBlob, baos); } catch (Exception e) { } }

  • "SELECT TOP", "LEFT OUTER JOIN", "ORDER BY" gives extra rows

    - by Codesleuth
    I have the following Access query I'm running through OLE DB in .NET: SELECT TOP 25 tblClient.ClientCode, tblRegion.Region FROM (tblClient LEFT OUTER JOIN tblRegion ON tblClient.RegionCode = tblRegion.RegionCode) ORDER BY tblRegion.Region There are 431 records within tblClient that have RegionCode set to NULL. For some reason, the query above returns all these 431 records instead of the first 25. If I change the query to ORDER BY tblClient.Client (the name of the client) like so: SELECT TOP 25 tblClient.ClientCode, tblRegion.Region FROM (tblClient LEFT OUTER JOIN tblRegion ON tblClient.RegionCode = tblRegion.RegionCode) ORDER BY tblClient.Client I get the expected result set of 25 records, showing a mixture of region names and NULL values. Why is it that ordering by a field retrieved through a LEFT OUTER JOIN will the TOP clause not work?

  • How can I make a DateTimePicker display an empty string?

    - by brass-kazoo
    I would like to be able to display a DateTimePicker that has a default value of nothing, i.e. no date. For example, I have a start date dtTaskStart and an end date dtTaskEnd for a task, but the end date is not known, and not populated initially. I have specified a custom format of yyyy-MM-dd for both controls. Setting the value to null, or an empty string at runtime causes an error, so how can I accomplish this? I have considered using a checkbox to control the enabling of this field, but there is still the issue of displaying an initial value.. Edit: Arguably a duplicate of the question DateTimePicker Null Value (.NET), but the solution I found for my problem is not a solution for that question, so I think it should remain here for others to find..

  • How can I use this downloaded Class(es) on my Prototype Routine?

    - by O.C.
    I'm a newbie and I'm in need of some help. I'm working on a prototype for an app, but I'm learning at the same time. I want to display a popup image over a given UIView, but I would like it to behave like the UIAlertView or like the Facebook Connect for iPhone modal popup window, in that it has a bouncy, rubbber-band-like animation to it. I was able to find the following class(es) on the net, from someone who was trying to do something similar. He/she put this together, but there was no Demo, no instructions nor a way to contact them. Being that I am so new, I don't have any idea as to how to incorporate this into my code. This is the routine where I need the bouncy image to appear... //======================================================== // // productDetail // - (void) showProductDetail { _productDetailIndex++; if (_productDetailIndex > 7) { return; } else if (_productDetailIndex == 1) { NSString* filename = [NSString stringWithFormat:@"images/ICS_CatalogApp_0%d_ProductDetailPopup.png", _productDetailIndex]; [_productDetail setImageWithName:filename]; _productDetail.transform = CGAffineTransformMakeScale(0.1,0.1); [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; // other animations goes here _productDetail.transform = CGAffineTransformMakeScale(1,1); // other animations goes here [UIView commitAnimations]; } NSString* filename = [NSString stringWithFormat:@"images/ICS_CatalogApp_0%d_ProductDetailPopup.png", _productDetailIndex]; [_productDetail setImageWithName:filename]; _productDetail.x = (self.width - _productDetail.width); _productDetail.y = (self.height - _productDetail.height); } and here is the code I found... float pulsesteps[3] = { 0.2, 1/15., 1/7.5 }; - (void) pulse { self.transform = CGAffineTransformMakeScale(0.6, 0.6); [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:pulsesteps[0]]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(pulseGrowAnimationDidStop:finished:context:)]; self.transform = CGAffineTransformMakeScale(1.1, 1.1); [UIView commitAnimations]; } - (void)pulseGrowAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:pulsesteps[1]]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(pulseShrinkAnimationDidStop:finished:context:)]; self.transform = CGAffineTransformMakeScale(0.9, 0.9); [UIView commitAnimations]; } - (void)pulseShrinkAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:pulsesteps[2]]; self.transform = CGAffineTransformIdentity; [UIView commitAnimations]; } My routine is based on the Prototyping class given by Apple during WWDC 09. It may not be "correct" but it works as is. I just would like to add the animation to this image/screen to really make the concept clear.

  • referencing a WCF web service

    - by ErnieStings
    Our current project uses an asmx service. We want to keep this service for now, but would like to add an additional wcf service for ajax calls. I followed a procedure i found online to set up the service and it works fine with javascript in aspx files within that particular project but i'm unsure how to reference it in javascript files in a different project (in the same solution). If someone could point me in the right direction it would be much appreciated. Thanks, Shawn EDIT: i wish to make calls in javascript similar to the following: function Button1_onclick() { var service = new AjaxServices.TestService(); service.wcfTest(4, onSuccess, null, null); } function onSuccess(result){ document.getElementById("ajaxPlaceHolder").innerHTML = "<p>" + result + "</p>"; } // ]]> but i'm willing to explore the jQuery option as well.

  • Adding STI to Existing Table...

    - by keruilin
    I want to add STI to an existing table using a custom type column. Let's call this taste_type whose corresponding model is Fruit. In the Fruit model I have: set_inheritance_column :taste_type In my migration to add STI I have: class AddSTI < ActiveRecord::Migration def self.up add_column :fruits, :taste_type, :string, :limit => 100, :null => false Fruit.reset_column_information Fruit.find_by_id(1).update_attributes({:taste_type => 'Sour'}) end def self.down remove_column :fruits, :taste_type end end When I run the migration, I get the following error: Mysql::Error: Column 'taste_type' cannot be null: ... Any idea what's going? I can get the migration to run if I comment the set_inheritance_column in the Fruit model, then uncomment it after I run the migration. Obviously, I don't want to do this, however.

  • iphone/ipad adding adding and removing a subview doesnt work

    - by Mark
    Im have a slight amount of trouble adding a new view to my scene, I have the code like this: - (void) showMyDayView { NSLog(@"My Day View was touched"); MyDayViewController *temp = [[MyDayViewController alloc] initWithNibName: @"MyDayView" bundle:nil]; self.myDayViewController = temp; NSLog(@"superview: %@", [[self mainNavView] superview]); [[self mainNavView] removeFromSuperview]; NSLog(@"after removal main: %@", [self mainNavView]); NSLog(@"after removal view: %@", [self view]); NSLog(@"after removal superview: %@", [[self view] superview]); [[[self view] superview] addSubview: [self.myDayViewController view]]; [temp release]; } And when I run this code, the console says "after removal superview: (null)" so when I add the subView to the superview, nothing happens because the superview is null. Any ideas? Thanks Mark

  • MVC Rendered Partial, how to get partial/view model in main model post to controller

    - by user1475788
    I have a text file and when users upload the file, the controller action method parses that file using state machine and uses a generic list to store some values. I pass this back to the view in the form of an IEnumerable. Within my main view, based on this ienumerable list I render a partail view to iterate items and display labels and a textarea. Users could add their input in the text area. When the users hit the save button this ienumrable list from the partial view rendered is null. so please advice any solutions. here is my main view @model RunLog.Domain.Entities.RunLogEntry @{ ViewBag.Title = "Create"; Layout = "~/Views/Shared/_Layout.cshtml"; } @using (Html.BeginForm("Create", "RunLogEntry", FormMethod.Post, new { enctype = "multipart/form-data" })) { <div id="inputTestExceptions" style="display: none;"> <table class="grid" style="width: 450px; margin: 3px 3px 3px 3px;"> <thead> <tr> <th> Exception String </th> <th> Comment </th> </tr> </thead> <tbody> @if (Model.TestExceptions != null) { foreach (var p in Model.TestExceptions) { Html.RenderPartial("RunLogTestExceptionSummary", p); } } </tbody> </table> </div> } partial view as follows: @model RunLog.Domain.Entities.RunLogEntryTestExceptionDisplay <tr> <td> @Model.TestException@ </td> <td>@Html.TextAreaFor(Model.Comment, new { style = "width: 200px; height: 80px;" }) </td> </tr> Controller action [HttpPost] public ActionResult Create(RunLogEntry runLogEntry, String ServiceRequest, string Hour, string Minute, string AMPM, string submit, IEnumerable<HttpPostedFileBase> file, String AssayPerformanceIssues1, IEnumerable<RunLogEntryTestExceptionDisplay> models) { } The problem is test exceptions which contains exception string and comment is comming back null.

  • TreeMap randomly stops properly returning values

    - by smessing
    I have the following TreeMap: TreeMap<String, Integer> distances = new TreeMap<String, Integer>(); and it contains both strings, "Face" and "Foo", with appropriate values, such that: System.out.println(distances); Yields: {Face=12, Foo=2} However, distances.get(Face) returns null, even though distances.get(Foo) properly returns 2. Previously, distances.get(Face) worked, but for some reason, it stopped working. Note I print out the map right before calling get() for both keys, so I haven't accidentally changed Face's value to null. Has anyone else ever encountered this problem? Is there anything I can do? I'm having a terrible time simply trying to figure out how to debug this problem.

  • Strcpy() corrupts the copied string in Solaris but not Linux

    - by strictlyrude27
    Hi all, I'm writing a C code for a class. This class requires that our code compile and run on the school server, which is a sparc solaris machine. I'm running Linux x64. I have this line to parse (THIS IS NOT ACTUAL CODE BUT IS INPUT TO MY PROGRAM): while ( cond1 ){ I need to capture the "while" and the "cond1" into separate strings. I've been using strtok() to do this. In Linux, the following lines: char *cond = NULL; cond = (char *)malloc(sizeof(char)); memset(cond, 0, sizeof(char)); strcpy(cond, strtok(NULL, ": \t\(){")); //already got the "while" out of the line will correctly capture the string "cond1".Running this on the solaris machine, however, gives me the string "cone1". Note that in plenty of other cases within my program, strings are being copied correctly. (For instance, the "while") was captured correctly. Does anyone know what is going on here?

Below is part of my code: BufferedInputStream bis = null; BufferedOutputStream bos = null; try { URL url = new URL(link); URLConnection urlConn = url.openConnection(); urlConn.addRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"); String contentType = urlConn.getContentType(); System.out.println("contentType:" + contentType); InputStream is = urlConn.getInputStream(); bis = new BufferedInputStream(is, 4 * 1024); bos = new BufferedOutputStream(new FileOutputStream( fileName.toString()));? Anyone could help me? Thanks in advance!
