  • How to add padding for background image

    - by michael
    Hi, I have a linear layout which has a background image (a 9 patched png file). How can I add padding to left and right so that the background image does not take up the whole width? I have tried 'android:paddingLeft' and 'android:paddingRight', but that does not change anything. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingLeft="25dip" android:paddingRight="25dip" android:background="@drawable/background"> The whole background still stretches the whole screen width. Thank you for any help.

  • regular expression repeating subexpression

    - by Michael Z
    I have the following text <pattern name="pattern1"/> <success>success case 1</success> <failed> failure 1</failed> <failed> failure 2</failed> <unknown> unknown </unknown> <pattern name="pattern2"/> <success>success case 2</success> <otherTag>There are many other tags.</otherTag> <failed> failure 3</failed> And the regular expression <failed>[\w|\W]*?</failed> matches all the lines contains failed tag. What do I need to to if I want to include the lines contains pattern tag as well? Basically, I want the following output: <pattern name="pattern1"/> <failed> failure 1</failed> <failed> failure 2</failed> <pattern name="pattern2"/> <failed> failure 3</failed> I am doing this in javascript, I do not mind of doing some intermediate steps.

  • C++ Problem: Class Promotion using derived class

    - by Michael Fitzpatrick
    I have a class for Float32 that is derived from Float32_base class Float32_base { public: // Constructors Float32_base(float x) : value(x) {}; Float32_base(void) : value(0) {}; operator float32(void) {return value;}; Float32_base operator =(float x) {value = x; return *this;}; Float32_base operator +(float x) const { return value + x;}; protected: float value; } class Float32 : public Float32_base { public: float Tad() { return value + .01; } } int main() { Float32 x, y, z; x = 1; y = 2; // WILL NOT COMPILE! z = (x + y).Tad(); // COMPILES OK z = ((Float32)(x + y)).Tad(); } The issue is that the + operator returns a Float32_base and Tad() is not in that class. But 'x' and 'y' are Float32's. Is there a way that I can get the code in the first line to compile without having to resort to a typecast like I did on the next line?

  • Setup database for Unit tests with Spring, Hibernate and Spring Transaction Support

    - by Michael Bulla
    I want to test integration of dao-layer with my service-layer in a unit-test. So I need to setup some data in my database (hsql). For this setup I need an own transaction at the begining of my testcase to ensure that all my setup is really commited to database before starting my testcase. So here's what I want to achieve: // NotTranactional public void doTest { // transaction begins setup database // commit transaction service.doStuff() // doStuff is annotated @Transactional(propagation=Propagation.REQUIRED) } Here is my not working code: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"/asynchUnit.xml"}) @DirtiesContext(classMode=ClassMode.AFTER_EACH_TEST_METHOD) public class ReceiptServiceTest implements ApplicationContextAware { @Autowired(required=true) private UserHome userHome; private ApplicationContext context; @Before @Transactional(propagation=Propagation.REQUIRED) public void init() throws Exception { User user = InitialCreator.createUser(); userHome.persist(user); } @Test public void testDoSomething() { ... } } Leading to this exception: org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63) at org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:687) at de.diandan.asynch.modell.GenericHome.getSession(GenericHome.java:40) at de.diandan.asynch.modell.GenericHome.persist(GenericHome.java:53) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:318) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:196) at $Proxy28.persist(Unknown Source) at de.diandan.asynch.service.ReceiptServiceTest.init(ReceiptServiceTest.java:63) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:27) at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:74) at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:83) at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:72) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:231) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:71) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:174) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:49) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) I dont know whats the right way to get the transaction around setup database. What I tried: @Before @Transactional(propagation=Propagation.REQUIRED) public void setup() { setup database } - Spring seems not to start transaction in @Before-annotated methods. Beyond that, thats not what I really want, cause there are a lot merhods in my testclass which needs a slightly differnt setup, so I need several of that init-methods. @Transactional(propagation=Propagation.REQUIRED) public void setup() { setup database } public void doTest { init(); service.doStuff() // doStuff is annotated @Transactional(propagation=Propagation.REQUIRED) } -- init seems not to get started in transaction What I dont want to do: public void doTest { // doing my own transaction-handling setup database // doing my own transaction-handling service.doStuff() // doStuff is annotated @Transactional(propagation=Propagation.REQUIRED) } -- start mixing springs transaction-handling and my own seems to get pain in the ass. @Transactional(propagation=Propagation.REQUIRED) public void doTest { setup database service.doStuff() } -- I want to test as real as possible situation, so my service should start with a clean session and no transaction opened So whats the right way to setup database for my testcase?

  • Can an ActiveRecord before_save filter halt the save without halting the transaction?

    - by Michael Boutros
    Is there any way for a before_save filter to halt the entire save without halting the transaction? What I'm trying to do is have a "sample" version of my model that the user can interact with and save but the changes themselves are never actually saved. The following will halt the transaction and (naturally) return false when I call @model.update_attributes: before_filter :ignore_changes_if_sample def ignore_changes_if_sample if self.sample? return false end end Thanks!

  • Oauth2 External Browser Request - App Launches, Credentials received, Browser Not Updated

    - by Michael Drozdowski
    I'm using an external browser request to authenticate myself with the SoundCloudAPI in OSX. My app launches, and has a button that opens an external browser window to authenticate against SoundCloud. When I click "connect" in the new window, I get a "External Protocol Request" that is consistent with my custom launch URI scheme. Clicking this loads the app, and it gets the correct credentials. The trouble is, the browser window never changes - it simply says that it's connecting forever. There is no "connection confirmed" alert coming from SoundCloud. I know I'm logged in because I can make the correct calls to the API to get things such as my username. Why isn't the browser confirming the connection or dismissing? The same thing happens if I load the authentication in an internal WebView in the app.

  • SqlCeCommand ExecuteNonQuery performance issue

    - by Michael
    I've been asked to resolve an issue with a .Net/SqlServerCe application. Specifically, after repeated inserts against the db, performance becomes increasingly degraded. In one instance at ~200 rows, in another at ~1000 rows. In the latter case the code being used looks like this: Dim cm1 As System.Data.SqlServerCe.SqlCeCommand = cn1.CreateCommand cm1.CommandText = "INSERT INTO Table1 Values(?,?,?,?,?,?,?,?,?,?,?,?,?)" For j = 0 To ds.Tables(0).Rows.Count - 1 'this is 3110 For i = 0 To 12 cm1.Parameters(tbl(i, 0)).Value = Vals(j,i) 'values taken from a different db Next cm1.ExecuteNonQuery() Next The specifics aren't super important (like what 'tbl' is, etc) but rather whether or not this code should be expected to handle this number of inserts, or if the crawl I'm witnessing is to be expected.
