  • Button layed out using layout_toLeftOf in a RelativeLayout does not show up

    - by rodion
    Hello all, I am trying to layout a Button to the left of a TextView that is centered on the screen. My layout looks like this: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="foo" android:id="@+id/center" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Left button" android:layout_toLeftOf="@id/center" /> </RelativeLayout> Unfortunately, the button just does not appear. I get the following result: As you see, the button doesn't show up. It works if I use layout_toRightOf, then the button appears to the right of the TextView, just as expected. Any ideas what I am doing wrong here?

  • How to retrieve all the records from a Berkeley DB in Ruby

    - by Federico Builes
    I'd like to be able to get all the key-values stored in a Berkeley DB using the Ruby bindings from http://github.com/mattbauer/bdb/tree/master but I'm not sure how to proceed. Any pointers will be appreciated. UPDATE Here's a small script that loops over the keys and prints them. Based on Pax' answer: require 'rubygems' require 'bdb' env = Bdb::Env.new(0) env.open('foo', Bdb::DB_CREATE,0) db = env.db db.open(nil, 'db1.db', nil, Bdb::Db::BTREE, Bdb::DB_CREATE,0) db.put(nil, 'key', 'value', 0) db.put(nil, 'key1', 'value1', 0) db.put(nil, 'key2', 'value2', 0) dbc = db.cursor(nil,0) key,val = dbc.get(nil,nil,Bdb::DB_FIRST) while key p key,val key,val = dbc.get(nil,nil,Bdb::DB_NEXT) end dbc.close db.close(0) env.close

  • Flexbuilder won't launch...arrrgh!

    - by eco_bach
    In a panic since I'm trying to meet a deadline so appreciate any feedback on this. For some reason, Flexbuilder 3 on my mac won't launch, crashes on startup. I've never experienced this before. Checked the .log file and what seems to be the problem is the following /Users/foo/Library/Preferences/Macromedia/Flash Player/#Security/FlashPlayerTrust/flexbuilder.fbr (No such file or directory) WTF is the flexbuilder.fbr??? Googled but not much luck. The only thing I've done that might have caused this is change flash player versions system wide using the official flash player uninstaller...but obviously this should not happen Any feedback appreciated...

  • Active directory select and display with asp.net (oledb) (error code: DB_E_ERRORSINCOMMAND(0x80040E1

    - by Phil
    I am trying to make a page which displays some user information returned from active directory. Here is my code so far: Dim oConnection As OleDbConnection Dim oCmd As OleDbCommand Dim strADOQuery As String Dim oleReader As OleDbDataReader oConnection = New OleDbConnection() oCmd = New OleDbCommand() oConnection.ConnectionString = "Provider=ADsDSOObject;" oConnection.Open() oCmd.Connection = oConnection strADOQuery = "select distinguishedName, cn, givenname, sn, mail, middleName, displayName, description, telephonenumber, physicalDeliveryOfficeName, employeeID from 'LDAP://dc=foo,dc=ac,dc=uk' WHERE objectCategory='Person' AND objectClass='user' AND sAMAccountName='" & Uname & "'""" oCmd.CommandText = strADOQuery oCmd.CommandTimeout = 600 oCmd.ExecuteReader() While oleReader.Read ADDN = r("distinguishedName") ADCommonName = r("cn") ADFirstName = r("givenname") ADLastName = r("sn") ADEmail = r("mail") ADFirstandLast = r("displayName") ADDescription = r("description") ADTelephone = r("telephonenumber") ADOffice = r("physicalDeliveryOfficeName") ADStaffnum = r("employeeID") End While oConnection.Close() oleReader.Close() I'm finding it hard to see exactly what is wrong with the code. The error message presented is vague: 'ADsDSOObject' failed with no error message available, result code: DB_E_ERRORSINCOMMAND(0x80040E14). Any assistance would be greatly appreciated Thanks.

  • Hibernate Schema Validation Fails on Oracle Table Synonyms

    - by Rob
    I'm developing a Java web application that uses Hibernate (annotations-based) for persisting entities to an Oracle 11g database. The DBA created synonyms for the tables and requested that I use these synonyms instead of the physical tables. (Eg: Table "Foo" has synonym "S_Foo") If I have "hibernate.hbm2ddl.auto=validate" enabled, then the application fails on startup with "Missing Table: S_Foo". If I turn off the validation, then the app starts up fine and works properly. My guess is that Hibernate only checks against physical tables and not synonyms when validating that a table exists. Is there any way to enable Hibernate schema validation with synonyms? Can I specify both a physical table and a synonym in the annotation? I prefer having that extra safety check that the table structure is correct when the application starts up.

  • Oracle analytic functions for "the attribute from the row with the max date"

    - by tpdi
    I'm refactoring a colleague's code, and I have several cases where he's using a cursor to get "the latest row that matches some predicate": His technique is to write the join as a cursor, order it by the date field descending, open the cursor, get the first row, and close the cursor. This requires calling a cursor for each row of the result set that drives this, which is costly for many rows. I'd prefer to be able to join, but what something cheaper than a correlated subquery: select a.id_shared_by_several_rows, a.foo from audit_trail a where a.entry_date = (select max(a.entry_date) from audit_trail b where b.id_shared_by_several_rows = a.id_shared_by_several_rows ); I'm guessing that since this is a common need, there's an Oracle analytic function that does this?

  • How can I get full filenames from Git difftool (for Microsoft Word "Compare Documents" feature)?

    - by Doug
    I am using the latest version of Git (1.6.6) on a Mac. My wife wants to use Git to manage her fiction writing as long as she can still use Microsoft Word 2008 (Mac). Instead of pushing her into saving everything as plain text, I would like to use Git Difftool to pass the files to Word and use Word's Compare Documents feature. She wouldn't be able to use Git Diff since Word docs are binary files but she could still use Git Difftool. I have written an Applescript which takes two filenames in this format: /Users/foo/Documents/my_novel.docx and opens Word to do the file comparison. However, Git Difftool seems to only pass the bare filenames (e.g. my_novel.docx) as parameters. Is there anyway to get the full filenames from Git Difftool? Thanks, Doug

  • WYSIWYG browser editor that generates *good* HTML?

    - by dauerbaustelle
    I'm searching for a "suck less" WYSIWYG browser HTML editor that generates good HTML code. (no <font>, <foo style="...">, <p></p><span></span><p><span>&nbsp;</span><span><span>blah</span></<span></p> and so on -- <b> and <i> etc is ok). Should be easy-to-use as it is going to be used by people that do not know what HTML is. Any suggestions? (I found a lot of editors but they all create that <font> and nested <span> crap that breaks site design and bloats a site with one table up to 100kB.)

  • Django and ImageField Question

    - by Hellnar
    Hello I have a such model: Foo (models.Model): slug = models.SlugField(unique=True) image = models.ImageField(upload_to='uploads/') I want to do two things with this: First of all, I want my image to be forced to resize to a specific width and height after the upload. I have tried this reading the documentation but seems to getting error: image = models.ImageField(upload_to='uploads/', height_field=258, width_field=425) Secondly, when adding an item via admin panel, I want my image's file name to be renamed as same as slug, if any issue arises (like if such named image already exists, add "_" to the end as it used to do. IE: My slug is i-love-you-guys , uploaded image such have i-love-you-guys.png at the end.

  • Name "main::a" used only once: possible typo at ... line ...

    - by knorv
    When running the following Perl code ... use Data::Traverse qw(traverse); use warnings; my $struct = [ 1, 2, { foo => 42 }, [ 3, 4, [ 5, 6, { bar => 43 } ] ], 7, 8 ]; traverse { print "$a => $b\n" if /HASH/ } $struct; ... the warning Name "main::[ab]" used only once: possible typo is given. Since the use of $a and $b is clearly not a typo in this case I want to get rid of the warning. How do I do that while still using warnings?

  • SWIG: Python list to uint32_t *?

    - by Lee Crabtree
    I'm trying to work with a Python module that was generated by SWIG. There's a C++ class defined that works like this (simplified): namespace Foo { class Thing { public: Thing(); ~Thing(); bool DoSomething(uint32_t x, uint32_t y, uint32_t z, uint32_t *buffer); }; }; When I try to call it from Python, I get an error about the last argument needing to be of type 'uint32_t*'. Normal Python integers work just fine for the other arguments, so I can't understand why a list of ints wouldn't work for the buffer. Any suggestions?

  • C++ Winsock non-blocking/async UDP socket

    - by Ragnagard
    Hi all! I'm developping a little data processor in c++ over UDP sockets, and have a thread (just one, and apart the sockets) that process the info received from them. My problem happens when i need to receive info from multiple clients in the socket at the same time. How could i do something like: Socket foo; /* init socket vars and attribs */ while (serving){ thread_processing(foo_info); } for multiple clients (many concurrent access) in c++? I'm using winsocks atm on win32, but just get standard blocking udp sockets working. No gui, it's a console app. I'll appreciate so much an example or pointer to one ;). Thanks in advance.

  • Django query if field value is one of multiple choices

    - by Nathan
    Say I want to model a system where a piece of data can have multiple tags (e.g. a question on a StackOverflow is the data, it's set of tags are the tags). I can model this in Django with the following: class Tag(models.Model): name = models.CharField(10) class Data(models.Model): tags = models.ManyToManyField(Tag) Given a set of strings, what's the best way to go about finding all Data objects that have one of these strings as the name of a tag in their tag list. I've come up with the following, but can't help thinking there is a more "Djangonic" way. Any ideas? tags = [ "foo", "bar", "baz" ] q_objects = Q( tags__name = tags[0] ) for t in tags[1:]: q_objects = q_objects | Q( tags__name = t ) data = Data.objects.filter( q_objects ).distinct()

  • JSP Custom Taglib: Nested Evaluation

    Say I have my custom taglib: <%@ taglib uri="http://foo.bar/mytaglib" prefix="mytaglib"%> <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%> <mytaglib:doSomething> Test </mytaglib:doSomething> Inside the taglib class I need to process a template and tell the JSP to re-evaluate its output, so for example if I have this: public class MyTaglib extends SimpleTagSupport { @Override public void doTag() throws JspException, IOException { getJspContext().getOut().println("<c:out value=\"My enclosed tag\"/>"); getJspBody().invoke(null); } } The output I have is: <c:out value="My enclosed tag"/> Test When I actually need to output this: My enclosed tag Test Is this feasible? How? Thanks.

  • URLEncoding a string with Objective-C

    - by Chris
    I'm trying to URL encode a string to form a GET request from objective-c. NSString *params = @"'Decoded data!'/foo.bar:baz"; NSRunAlertPanel( @"Error", [params urlEncoded], @"OK", nil, nil ); This is the category extending NSString -(NSString *) urlEncoded { NSString *encoded = (NSString *)CFURLCreateStringByAddingPercentEscapes( NULL, (CFStringRef)self, NULL, (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ", kCFStringEncodingUTF8 ); return encoded; } So the first time I run it I get back 1606410046ecoded 1606410784ata2270.000000foo.bar0X1.001716P-1042baz from the dialog box. Immediately after I run it again I get this 1606410046ecoded 1606410944ata227369374562920703448982951250259562309742470533728899744288431318481119278377104028261651081181287077973859930826299575521579020410425419424562236383226511593137467590082636817579938932512039895040.000000foo.bar0X1.66E6156303225P+771baz Then if I run it AGAIN it goes back to the first one. It's really weird. If params is set to @"&" or @" " I just get back a "2" (w/o the quotes) in the dialog box. Also is there a way I can have the % signs be shown in the alert dialog? Thanks

  • Python serialize lexical closures?

    - by dsimcha
    Is there a way to serialize a lexical closure in Python using the standard library? pickle and marshal appear not to work with lexical closures. I don't really care about the details of binary vs. string serialization, etc., it just has to work. For example: def foo(bar, baz) : def closure(waldo) : return baz * waldo return closure I'd like to just be able to dump instances of closure to a file and read them back. Edit: One relatively obvious way that this could be solved is with some reflection hacks to convert lexical closures into class objects and vice-versa. One could then convert to classes, serialize, unserialize, convert back to closures. Heck, given that Python is duck typed, if you overloaded the function call operator of the class to make it look like a function, you wouldn't even really need to convert it back to a closure and the code using it wouldn't know the difference. If any Python reflection API gurus are out there, please speak up.

  • Workflow Foundation: How to create Receive activity with custom message in xaml designer?

    - by Petr Felzmann
    I need to have Receive activity which can receive my custom data. I found examples, but all use coded workflows like such public class ProcessRequest : Activity { public ProcessRequest() { Variable request = new Variable { Name = "request" }; Receive receiveRequest = new Receive { ServiceContractName = "IProcessRequest", OperationName = "Foo", CanCreateInstance = true, Content = ReceiveContent.Create(new OutArgument(request)) }; } } The main point is that Receive.Content property. It is not clear for me how I can do it in XAML designer. What I have to set in the dialog of the Content property - Message or Parameters and what to set inside those options? Thanks for the light!

  • Custom UISwitch & App Store approval

    - by pix0r
    After doing some reading, I've found that you can customize the text and color on a UISwitch control. I'm curious if these methods will cause problems trying to get my app approved and included in the App Store. Sample code taken from iPhone Developer's Cookbook Sample Code: // Custom font, color switchView = [[UICustomSwitch alloc] initWithFrame:CGRectZero]; [switchView setCenter:CGPointMake(160.0f,260.0f)]; [switchView setLeftLabelText: @"Foo"]; [switchView setRightLabelText: @"Bar"]; [[switchView rightLabel] setFont:[UIFont fontWithName:@"Georgia" size:16.0f]]; [[switchView leftLabel] setFont:[UIFont fontWithName:@"Georgia" size:16.0f]]; [[switchView leftLabel] setTextColor:[UIColor yellowColor]];

  • web development with ruby without rails?

    - by kmorris511
    For reasons beyond my control, I'm being tasked with Ruby web development that does NOT use Rails or really any other heavyweight framework such as Merb. I'm wondering if anybody else has encountered this and can recommend best practices or resources that describe best practices for such a problem. I'd like to avoid the dreaded out.print('<td class="foo">'+some_data+'</td>') style of web development. A coworker has suggested Rack as a light framework but the documentation is sketchy and it seems unproven in the market.

  • Hibernates generates VARBINARY column with JPA @Enumerated annotation

    - by tran
    Hibernates is generating a VARBINARY column with JPA @Enumerated annotation. I'm using SQL Server 2005 w/ JTDS driver. The mapping is dirt simple: @Basic @Enumerated(EnumType.ORDINAL) private MyEnum foo; I would have expected Hibernate to generate an integer column? I've also tried EnumType.STRING (expecting a varchar column) with no success. Note that my app works fine; the column type makes it hard to inspect the DB, and to issue adhoc SQL when poking at the database.

  • How to use NSPredicate for Key-Path values

    - by randombits
    Using an NSPredicate for an array is rather straight forward using filteredArrayUsingPredicate:. How is this done for key-path values? Meaning, I have an array of objects (in this case, the objects are of the same type). The objects each have an instance variable called name. As per the documentation, it says to do the following: NSPredicate *predicate = [NSPredicate predicateWithFormat: @"ANY employees.firstName like 'Matthew'"]; Is that -also- used in filteredArrayUsingPredicate? What if I have an array of People objects? does that mean I would use: NSArray *allPeopleObjects; // pre-populated NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY people.name like 'Foo'"]; NSArray *matching = [allPeopleObjects filteredArrayUsingPredicate:predicate]; Documentation is a bit lacking in that department.

  • How do you give variables reference in javascript?

    - by Eric
    I want to give variables reference in javascript. For example, I want to do: a=1 b=a a=2 and have b=2, and change accordingly to a. Is this possible in javascript? If it isn't is there a way to do like a.onchange = function () {b=a}? What I wanted to do was make a function like makeobject which make an object and puts it in an array and than returns it like function makeobject() { objects[objects.length] = {blah:'whatever',foo:8}; } so than I could do a=makeobject() b=makeobject() c=makeobject() and later in the code do for (i in objects) { objects[i].blah = 'whatev'; } and also change the values of a,b and c
