  • make target is never determined up to date

    - by Michael
    Cygwin make always processing $(chrome_jar_file) target, after first successful build. So I never get up to date message and always see commands for $(chrome_jar_file) are executing. However it happens only on Windows 7. On Windows XP once it built and intact, no more builds. I narrowed down the issue to one prerequisite - $(jar_target_dir). Here is part of the code # The location where the JAR file will be created. jar_target_dir := $(build_dir)/chrome # The main chrome JAR file. chrome_jar_file := $(jar_target_dir)/$(extension_name).jar # The root of the JAR sources. jar_source_root := chrome # The sources for the JAR file. jar_sources := bla #... some files, doesn't matter jar_sources_no_dir := $(subst $(jar_source_root)/,,$(jar_sources)) $(chrome_jar_file): $(jar_sources) $(jar_target_dir) @echo "Creating chrome JAR file." @cd $(jar_source_root); $(ZIP) ../$(chrome_jar_file) $(jar_sources_no_dir) @echo "Creating chrome JAR file. Done!" $(jar_target_dir): $(build_dir) echo "Creating jar target dir..." if [ ! -x $(jar_target_dir) ]; \ then \ mkdir $(jar_target_dir); \ fi $(build_dir): @if [ ! -x $(build_dir) ]; \ then \ mkdir $(build_dir); \ fi so if I just remove $(jar_target_dir) from $(chrome_jar_file) rule, it works fine.

  • Grails: can remoteField update multiple fields?

    - by Michael Bavin
    Hi, Assume i have a book entity with an isbn field. When entered a isbn number, i want 2 fields to be updated: title and author. My controller looks like this: def ajaxGetBook = { def book = Book.findByIsbn(params.isbn) if(book==null) book = new Book() render book as JSON } So my call works, and i get a full JSON Book. Now i would like to update 2 texfields by the update attribute <g:remoteField action="ajaxGetBook" update="title" name="isbn" value="${bookInstance?.book?.isbn}" paramName="isbn"/> Now the title field gets updated with the full book object, so that doesn't work. Is it possible to update field title with only the JSON book.title? Is it possible to update more fields at once? I could render book.title as JSON but that works for only one field. Thank you

  • MySQL: LOAD DATA reclaim disk space after delete

    - by Michael
    I have a DB schema composed of MYISAM tables, i am interested to delete old records from time to time from some of the tables. I know that delete does not reclaim the memory space, but as i found in a description of DELETE command, inserts may reuse the space deleted In MyISAM tables, deleted rows are maintained in a linked list and subsequent INSERT operations reuse old row positions. I am interested if LOAD DATA command also reuses the deleted space? UPDATE I am also interested how the index space reclaimed?

  • "Reloading" Bindings in Ninject2?

    - by Michael Stum
    I'm using Ninject2 for DI and I have a Module that loads data from a config file. I wonder if there is a way to tell the Kernel or the Module to reload the config? (I can trigger that through code if needed) What worries me is the lifetime of existing objects. Say I have ITest bound to TestImpl1 in Singleton Scope and I change the config to bind ITest to TestImpl2 instead. All new requests should get TestImpl2, but the classes that already requested TestImpl1 before obviously keep it. However, what if all users of TestImpl1 are gone - will TestImpl1 be properly garbage collected and disposed in case it implements IDisposable? Or will it just be orphaned? Do I have to loop through each type and call Unbind/Bind on it? Or can I just unload the entire Module and reload it while still managing any existing object?

  • What is the equivalent of Java's .length for arrays in C#?

    - by Michael Loftus
    I'm new to C#, and I'm trying to convert this code from java into C#. static public double euclidean_2(double[] x, double[] y) { if (x.length != y.length) throw new RuntimeException("Arguments must have same number of dimensions."); double cumssq = 0.0; for (int i = 0; i < x.length; i++) cumssq += (x[i] - y[i]) * (x[i] - y[i]); return cumssq; } I know java uses .length but what is the equivalent in C# since I keep getting an error Thanks

  • How to access a subset of XML data in Java when the XML data is too large to fit in memory?

    - by Michael Jones
    What I would really like is a streaming API that works sort of like StAX, and sort of like DOM/JDom. It would be streaming in the sense that it would be very lazy and not read things in until needed. It would also be streaming in the sense that it would read everything forwards (but not backwards). Here's what code that used such an API would look like. URL url = ... XMLStream xml = XXXFactory(url.inputStream()) ; // process each <book> element in this document. // the <book> element may have subnodes. // You get a DOM/JDOM like tree rooted at the next <book>. while (xml.hasContent()) { XMLElement book = xml.getNextElement("book"); processBook(book); } Does anything like this exist?

  • Preserving the GLBlendFunc

    - by Michael Minerva
    I need to preserve the current GlBlendFunc so can restore it after I do some work. It seems that this is not one of the attributes that can be saved with GLPushAttrib, is there some other similar method I can use to preserve the state?

  • jQuery slideDown() not animating (jquery-rails 3.0.4; jquery-ui-rails (4.0.5)

    - by Michael Guren
    I am following along in the latest Agile Web Development with Rails 4 book. In Chapter 11 (AJAX), the book instructs us to use the following code in the "create.js.erb" file: if ($('#cart tr').length == 1) { $('#cart').show('blind', 1000); } This code causes the #cart div to jump down without any content. After 1 second it appears. There is no sliding effect. I tried using slideDown(); as well, but the div just appears immediately. Out of curiosity, I tried slideUp(); when the div was visible. Voila. The div slid up. This appears to be a jQuery bug and wondered if anyone else has experienced this, or has any suggestions for me. Thanks.

  • 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.

  • How to create DataSource dependency property on a wpf User Control

    - by Michael Hedgpeth
    I have a user control that wraps a grid. I want to be able to set the underlying grid's data source, but through the user control, like this: <my:CustomGrid DataSource="{Binding Path=CollectionView}" /> I have set this up in the grid like this: private static readonly DependencyProperty DataSourceProperty = DependencyProperty.Register("DataSource", typeof(IEnumerable), typeof(CustomGrid)); public IEnumerable DataSource { get { return (IEnumerable)GetValue(DataSourceProperty); } set { SetValue(DataSourceProperty, value); underlyingGrid.DataSource = value; } } But this doesn't work (it doesn't give me an error either). The data source is never set. What am I missing?

  • CSS:Hover's problem with text that is hidden because of overflow:hidden ?

    - by Michael Harringon
    In my application i have lots of divs containing text. All divs have overflow set to hidden so that the user does not see the text if the container is not large enough to contain the writing. If the user wants to see the hidden text they are supposed to mouse over the "box". The box then expands and shows the text. Sounds simple enough, right? Well i am having problems and the solution i tried did not work. The problem is that when the user mouses over the box, the text does indeed appears but stays really narrow and comes out of the bottom box, the sameway it would if overflow was set to visible. below is the standard css applied to the div box: .newevent { overflow: hidden; z-index: 0; } I Tried to fix this by setting a hover trigger, when it is activated the box widens, i thought that this would then mean there would be more space to display the text, below is the hover effect: .newevent div:hover { width: 200px; padding: 50px; background-color:#D4D4D4; border: medium red dashed; overflow: visible; z-index: 1; } How do i go about "redrawing" the text when it is hovered over, so that the text can use the new widened area rather than behaving as it is still in a narrow box.

  • C# Unit Testing: How do I set a Lazy<T>.ValueCreated to false?

    - by michael paul
    Basically, I have a unit test that gets a singleton instance of a class. Some of my tests required me to mock this singleton, so when I do Foo.Instance I get a different type of instance. The problem is that my checks are passing individually, but failing overall because one test is interfering with another. I tried to do a TestCleanup where I set: Foo_Accessor._instance = null; but that didn't work. What I really need is Foo_Accessor._instance.IsValueCreated = false; (_instance is a Lazy). Any way to unset the Lazy object that I didn't think of?

    I can firgure out how to push a UIView from a Tableview and have the "child" details appear. Here is the view I'm trying to load: Here is the code that checks for children and either pushes a itemDetail.xib or an additional UITable, I want to use the above .xib but load the correct contents "tableDataSource" into the UItable: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the dictionary of the selected data source. NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; if([Children count] == 0) { ItemDetailViewController *dvController = [[ItemDetailViewController alloc] initWithNibName:@"ItemDetailView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release]; } else { //Prepare to tableview. FirstTab *rvController = [[FirstTab alloc] initWithNibName:@"FirstView" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.CurrentLevel += 1; //Set the title; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } } Thanks for the help. I see lots of stuff on this but can't find the correct push instructions.

  • Ruby: totalling amounts

    - by Michael
    I have a Donation.rb model with an amount column that takes an integer. I want to sum all the individual donations together and show the total on the home page. In the home_controller, I'm doing @donations = Donation.all and then in the view I do <% sum = 0 %> <% @donations.each do |donation| %> <%= sum += donation.amount if donation.amount? %> <% end %> The problem is that this is printing the running sum each time a new donation is added to it. I just want the total sum at the end after they've all been added together.
