  • Set Android Gallery widget to show specific starting image

    - by Dalmazio Brisinda
    Hi all, I have a task where the user can select an image from a GridView representing a photo album, and from this I start a new activity which displays a Gallery widget to show the images of the photo album. However, I can't seem to get the Gallery widget to show the contents of the photo album with a given image as the starting point. Ideally I would like a Gallery#setStartingImage(int position) or something similar. Any ideas would be greatly appreciated. Best, Dalmazio

  • Regex with all optional parts but at least one required

    - by Alan Mendelevich
    I need to write a regex that matches strings like "abc", "ab", "ac", "bc", "a", "b", "c". Order is important and it shouldn't match multiple appearances of the same part. a?b?c? almost does the trick. Except it matches empty strings too. Is there any way to prevent it from matching empty strings or maybe a different way to write a regex for the task.

  • Initialization of ComboBox in datagrid, Silverlight 4.0

    - by Budda
    I have datagrid with list of MyPlayer objects linked to ItemsSource, there are ComboBoxes inside of grid that are linked to a list of inner object, and binding works correctly: when I select one of the item then its value is pushed to data model and appropriately updated in other places, where it is used. The only problem: initial selections are not displayed in my ComboBoxes. I don't know why..? Instance of the ViewModel is assigned to view DataContext. Here is grid with ComboBoxes (grid is binded to the SquadPlayers property of ViewModel): <data:DataGrid ="True" AutoGenerateColumns="False" ItemsSource="{Binding SquadPlayers}"> <data:DataGrid.Columns> <data:DataGridTemplateColumn Header="Rig." Width="50"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <ComboBox SelectedItem="{Binding Rigid, Mode=TwoWay}" ItemsSource="{Binding IntLevels, Mode=TwoWay}"/> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> </data:DataGrid.Columns> </data:DataGrid> Here is ViewModel class ('_model_DataReceivedEvent' method is called asynchronously, when data are received from server): public class SquadViewModel : ViewModelBase<SquadModel> { public SquadViewModel() { SquadPlayers = new ObservableCollection<SquadPlayer>(); } private void _model_DataReceivedEvent(List<SostavPlayerData> allReadyPlayers) { TeamTask task = new TeamTask { Rigid = 1 }; foreach (SostavPlayerData spd in allReadyPlayers) { SquadPlayer sp = new SquadPlayer(spd, task); SquadPlayers.Add(sp); } RaisePropertyChanged("SquadPlayers"); } And here is SquadPlayer class (it's objects are binded to the grid rows): public class SquadPlayer : INotifyPropertyChanged { public SquadPlayer(SostavPlayerData spd) { _spd = spd; Rigid = 2; } public event PropertyChangedEventHandler PropertyChanged; private int _rigid; public int Rigid { get { return _rigid; } set { _rigid = value; if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("Rigid")); } } } private readonly ObservableCollection<int> _statIntLevels = new ObservableCollection<int> { 1, 2, 3, 4, 5 }; public ObservableCollection<int> IntLevels { get { return _statIntLevels; } } It is expected to have all "Rigid" comboboxes set to "2" value, but they are not selected (items are in the drop-down list, and if any value is selected it is going to ViewModel). What is wrong with this example? Any help will be welcome. Thanks.

  • How to sed search and replace without changing ownership

    - by Ian
    I found this command line search and replace example: find . -type f -print0 | xargs -0 sed -i 's/find/replace/g' It worked fine except it changed the date and file ownership on EVERY file it searched through, even those that did not contain the search text. What's a better solution to this task? Thanks.

  • Managing Linux Directory Permissions & SFTP

    - by Dizzle
    Good morning; I have a RHEL 5.7 web server configured to allow SSH/SFTP only by specific groups. I'd like for content managers to upload content to their respective directories and have that content inherit the user/group ownership of the directory regardless of upload method or application. For example: John is in group "web" for SSH/SFTP rights and "finance" for directory permissions, and uploads to directory "webstuff" via SFTP. Directory "webstuff" has permissions of "2760" (rwxrws---), and ownership of "apache:finance". If John uploads an update to an existing file in "webstuff", the ownership of the file stays at "apache:finance". If John uploads a new file to "webstuff", the ownership of the file is "john:finance". My desire is to have any file from John uploaded to "webstuff" to change to the directory's owner. I've tried with setuid and setgid both set, but the user-ownership didn't take. I've seen mentions on ServerFault of using ACL's, or a chrooted jail for SFTP but I have yet to configure and test them, and I don't know if they're a viable solution (they could be, I just don't know because I've never done either). Any thoughts and assistance would be greatly appreciated.

  • Reliable and fast way to convert a zillion ODT files in PDF?

    - by Marco Mariani
    I need to pre-produce a million or two PDF files from a simple template (a few pages and tables) with embedded fonts. Usually, I would stay low level in a case like this, and compose everything with a library like ReportLab, but I joined late in the project. Currently, I have a template.odt and use markers in the content.xml files to fill with data from a DB. I can smoothly create the ODT files, they always look rigth. For the ODT to PDF conversion, I'm using openoffice in server mode (and PyODConverter w/ named pipe), but it's not very reliable: in a batch of documents, there is eventually a point after which all the processed files are converted into garbage (wrong fonts and letters sprawled all over the page). Problem is not predictably reproducible (does not depend on the data), happens in OOo 2.3 and 3.2, in Ubuntu, XP, Server 2003 and Windows 7. My Heisenbug detector is ticking. I tried to reduce the size of batches and restarting OOo after each one; still, a small percentage of the documents are messed up. Of course I'll write about this on the Ooo mailing lists, but in the meanwhile, I have a delivery and lost too much time already. Where do I go? Completely avoid the ODT format and go for another template system. Suggestions? Anything that takes a few seconds to run is way too slow. OOo takes around a second and it sums to 15 days of processing time. I had to write a program for clustering the jobs over several clients. Keep the format but go for another tool/program for the conversion. Which one? There are many apps in the shareware or commercial repositories for windows, but trying each one is a daunting task. Some are too slow, some cannot be run in batch without buying it first, some cannot work from command line, etc. Open source tools tend not to reinvent the wheel and often depend on openoffice. Converting to an intermediate .DOC format could help to avoid the OOo bug, but it would double the processing time and complicate a task that is already too hairy. Try to produce the PDFs twice and compare them, discarding the whole batch if there's something wrong. Although the documents look equal, I know of no way to compare the binary content. Restart OOo after processing each document. it would take a lot more time to produce them it would lower the percentage of the wrong files, and make it very hard to identify them. Go for ReportLab and recreate the pages programmatically. This is the approach I'm going to try in a few minutes. Learn to properly format bulleted lists Thanks a lot.

  • HT create a new vector in data frame that takes correlation of existing vectors

    - by Milktrader
    I have a time series of two indexes, with each row representing the closing price on the same day. I'd like to go to row 30 and lookback over the last 30 'days' and calculate the pearson correlation. And then store that value in a new vector. Then, repeat the calculation for the entire time series. It is a trivial task in Excel, so I'm convinced it can be done in R. I don't know the method to use though.

  • Converting to and from Unicode in PHP

    - by Chris
    Hey, I'm using php 5 and need to communicate with another server that runs completely in unicode. I need to convert every string to unicode before sending it over. This seems like an easy task, but I haven't been able to find a way to do it yet. Is there a simple function that returns a unicode string? i.e. convert_to_unicode("the string i'm sending")

  • What bugs apply to the different FindBugs reportLevels?

    - by Daniel H
    According to the Ant task, the report level is a low/medium/high setting that would look for bugs of different criticallity levels. However, there isn't anything I could find that explains which of the bugs apply to these different reporting levels. Is there somewhere that provides this, even if it is something I need to look at within the source?

  • python multithreading for dummies

    - by albruno
    trying to find a simple example that clearly shows a single task being divided for multi-threading. Quite frankly... many of the examples are overly sophisticated thus.... making the flow tougher to play with... anyone care to share their breakthrough sample or point to an example? As well, what is the best docs? many google lookups are too specific (for me at this stage) Thanks in advance.

  • How best to store Subversion version information in EAR's?

    - by Rene
    When receiving a bug report or an it-doesnt-work message one of my initials questions is always what version? With a different builds being at many stages of testing, planning and deploying this is often a non-trivial question. I the case of releasing Java JAR (ear, jar, rar, war) files I would like to be able to look in/at the JAR and switch to the same branch, version or tag that was the source of the released JAR. How can I best adjust the ant build process so that the version information in the svn checkout remains in the created build? I was thinking along the lines of: adding a VERSION file, but with what content? storing information in the META-INF file, but under what property with which content? copying sources into the result archive added svn:properties to all sources with keywords in places the compiler leaves them be I ended up using the svnversion approach (the accepted anwser), because it scans the entire subtree as opposed to svn info which just looks at the current file / directory. For this I defined the SVN task in the ant file to make it more portable. <taskdef name="svn" classname="org.tigris.subversion.svnant.SvnTask"> <classpath> <pathelement location="${dir.lib}/ant/svnant.jar"/> <pathelement location="${dir.lib}/ant/svnClientAdapter.jar"/> <pathelement location="${dir.lib}/ant/svnkit.jar"/> <pathelement location="${dir.lib}/ant/svnjavahl.jar"/> </classpath> </taskdef> Not all builds result in webservices. The ear file before deployment must remain the same name because of updating in the application server. Making the file executable is still an option, but until then I just include a version information file. <target name="version"> <svn><wcVersion path="${dir.source}"/></svn> <echo file="${dir.build}/VERSION">${revision.range}</echo> </target> Refs: svnrevision: http://svnbook.red-bean.com/en/1.1/re57.html svn info http://svnbook.red-bean.com/en/1.1/re13.html subclipse svn task: http://subclipse.tigris.org/svnant/svn.html svn client: http://svnkit.com/
