  • Sql: simultaneous aggregate from two tables

    - by Ash
    I have two tables: a Files table, which includes the file type, and a File Properties table, which references the file table via a foreign key. Sample Files table: | id | name | type | --------------------- | 1 | file1 | zip | | 2 | file2 | zip | | 3 | file3 | zip | | 4 | file4 | jpg | And the Properties table: | file_id | property | ----------------------- | 1 | x | | 2 | x | I want to make a query, which shows the count of each file type, and how many files of that type have a property. So in the example, the result would be | type | filecount | prop count | ---------------------------------- | zip | 3 | 2 | | jpg | 1 | 0 | I could accomplish this by select f.type, (select count(id) from files where type = f.type), count(fp.id) from files as f, file_properties as fp where f.id = fp.file_id group by f.type; But this seems very suboptimal and is very slow. Any better way to do this?

  • How to specify physical path in ASPX page?

    - by salvationishere
    I am developing a C# VS 2008 / SQL Server 2008 ASP.NET Web Applications project. In one of my ASPX files I am trying to reference the Master file, which is actually located in the parent website. In other words, when I open the parent website, I see this project listed. But when I open this project separately, I do not see parent website and this project is the root. So now how do I use the Master file from the parent website? Currently, I have in my ASPX file: <%@ Page Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeFile="EnhancedCreateUserWizard.aspx.cs" Inherits="Membership_EnhancedCreateUserWizard" Title="Untitled Page" %> But this won't work because it is a virtual path and since this project is the root, I can't access the Master file virtually. Instead I want to specify physical path. How accomplish I do this?

  • subversion 1.6.x losing changes on check-in

    - by Bernard
    I'm trying to figure out if this is a known issue with SVN 1.6.x Developer A modifies a file and commits it. Developer B modifies the same file. Tries to commit it and gets told local copy out of date so does an update and then a commit. However the changes from Developer A are lost so the resulting file only contains the version that Developer B checked in. We can see this in the logs. It seems to happen when the same file is modified but in different places. Anyone else experienced this? We've had it happen 4 or 5 times in the past few weeks and we've lost a half day or so each time trying to figure out what's been lost, etc. We're starting to lose confidence in SVN. Should we be thinking of moving to GIT or Mecurial? Would that sort out this problem?

  • How to Implement Backbone Java Logic Code into Android

    - by lord_sneed
    I wrote a program to work from the console in Eclipse and the terminal window in Linux. I am now transforming it into an Android app and I have the basic functionality of the Android UI done up until the point where it needs to use the logic from the Java file of the program I wrote. All of my inputs from the Java file are currently from the keyboard (from Scanners). My question is: how do I transform this to get it work with the user interaction of the app? The only input would be from the built in NumberPicker. Should I copy and paste the code from the Java program to the activity file in the onCreate method and change all of the input methods (Scanners) to work with the Android input? Or do I create variables in the activity file and pass them to the Java program (in the separate class)? (If so, how would I do that? the Java file starts from the main method: public static void main(String[] args) {) Also, will the print statements I have, System.out.println(...);, translate directly into the Android UI and print on the screen or do I have to modify those?

  • How to read remote video on Amazon S3 using ffmpeg

    - by virtualize
    I need to create poster frames from videos hosted on Amazon S3 via ffmpeg. So is there a way to use the remote video file directly in ffmpeg command line like this: ffmpeg -i "http://bucket.s3.amazonaws.com/video.mp4" -ss 00:00:10 -vframes 1 -f image2 "image%03d.jpg" ffmpeg just returns: http://bucket.s3.amazonaws.com/video.mp4: I/O error occurred Usually that means that input file is truncated and/or corrupted. I also tried forcing ffmpeg to use the videos mp4 container for reading: ffmpeg -f mp4 -i "http://bucket.s3.amazonaws.com/video.mp4" ... But no luck. Wget this video from S3 and processing it locally works fine of course, as well as reading the file remotely from other 'standard' http servers. So I know that ffmpeg supports remote file reading, but why not on S3?

  • Django Interrupted system call when sending email

    - by mhost
    Hi, Sometimes, when submitting a form (pretty much any form on my site that sends me an email), I get the following error: File "/usr/lib/python2.5/smtplib.py", line 603, in starttls (resp, reply) = self.docmd("STARTTLS") File "/usr/lib/python2.5/smtplib.py", line 378, in docmd return self.getreply() File "/usr/lib/python2.5/smtplib.py", line 352, in getreply line = self.file.readline() File "/usr/lib/python2.5/socket.py", line 381, in readline data = self._sock.recv(self._rbufsize) error: (4, 'Interrupted system call') My code is sending email via gmail. I am also using django contact-form which does the same thing. The problem doesn't always happen. It seems very random. At one point today it got so bad that it displayed the error every time I submitted a form. Restarting apache fixes the problem for one submission and then it does it again. I have checked the RAM and there is plenty available (about 350MB available). Can someone lead me in the right direction? What does this error mean? What can I do to prevent this. Thanks.

  • How can I import the sqlite3 module into Python 2.4?

    - by Tony
    The sqlite3 module is included in Python version 2.5+. However, I am stuck with version 2.4. I uploaded the sqlite3 module files, added the directory to sys.path, but I get the following error when I try to import it: Traceback (most recent call last): File "<stdin>", line 1, in ? File "sqlite3/__init__.py", line 23, in ? from dbapi2 import * File "sqlite3/dbapi2.py", line 26, in ? from _sqlite3 import * ImportError: No module named _sqlite3 The file '_sqlite3' is in lib-dynload, but if I include this in the sqlite3 directory, I get additional errors. Any suggestions? I am working in a limited environment; I don't have access to GCC, among other things.

  • Bash script with regex not behaving on Ubuntu

    - by user265330
    I have a Bash script that is working on my OpenSuSE box, but when copied across to my Ubuntu box, is not working. The script reads in from a file. The file has fields separated by white space (tabs and spaces). #!/bin/bash function test1() { while read LINE do if [[ $LINE =~ "^$" || $LINE =~ "^#.*" ]] ; then continue; fi set -- $LINE local field1=$1 local field2=$2 done < test.file } test1 with test.file containing: # Field1Header Field2Header abcdef A-2 ghijkl B-3 There seem to be two problems: (1) $field2, the one with the hyphen, is blank (2) The regex to strip out the blank lines and lines that start with # is not working Anyone know what's wrong? As I said, it works fine on OpenSuSE. Thanks, Paul

  • visual-studio-2008 versioninfo for all files updated from one place

    - by ravenspoint
    The version information, displayed when the mouse cursor hovers over the file in windows explorer, is set for a file built by visual studio in the VERSION resource. I would like to set the version in one place for all the files built by a solution, preferably when I change the version in the install properties. Is there a way to do this? The motivation for this is that if the version is not updated for a file, then the installer will leave previous versions of files instead of replacing them with new files. This happens even when the 'RemovePreviousVersions' property is set. In order to save the tedious and error prone task of updating the version in every file built and installed, I remove the version resource from all files - which is not elegant.

Tversity shows up on my Xbox 360, but when i click on it, it just loads and loads and after a minute it times out and tells me it can't connect. Has anyone successfully gotten this working?

  • ASP.NET DropDownList Replacement

    - by user302004
    Currently, I'm populating a drop down list when a file is created in a configurable folder. if (!downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.FullName)) Then, I add the file and remove "No Responses Available". However, if the same file is resubmitted (i.e., the file name is the same but the timestamp is different), then I want to remove the older entry and replace it with a new entry in the drop down list. I have the filename, so I go into the "else" block from the line of code above. From there, I'm checking to see if I have the same filename and a different creation time. if (downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.FullName) && downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.CreationTime) From here, I want to find the position, remove it, and add the new text. This approach isn't working. Can anyone offer an alternate approach?

  • Adobe Air: Read and Write MP3 or JPG from local directory and switch bytes

    - by Max
    I would like to make my local jpg and mp3 files kind of unreadable (without encoding) by just putting the first 100 bytes from the beginning of the file to the end and then saving the file with a .dat extension. I know I have to use the byte array but can't get it work. I would also need then a small function to read that file and put the 100bytes back to the front so that I can play/display the file. It would be great if you could post the whole function because I am quite new to Air so that I fully understand. Thank You!!!!

  • Trouble dragging and dropping gui components onto other .net forms using NHibernate

    - by IsaacB
    Hi, using VS2008, here. I have a GUI component that loads some stuff from a database mapped by nhibernate in its constructor. When I drag and drop this component onto another form from the toolbox, NHibernate complains that it can't find the config file in program files\visual studio 9\common7\ide. Why is it looking here for the cfg file? I'm actually calling database stuff through another project in the same solution, and the cfg file is located at the root of that project. copy/pasting the cfg file over to there does work, but I'm working with svn here and I don't want to have configuration files outside the repository. Something else that would help would be turning off how it tries to load the data in the form design screen. How would I do that?

  • Drupal: Programmatically saving imagefield images

    - by Ace
    Hey there! I'm trying to write a sync function that saves some data to nodes, which works fine, until I try to save the thumbnail image associated with the node. I've managed to download the file and put it in my sites/default/files folder, but what's the best way to tell Drupal, "put this file in that CCK imagefield"? EDIT To clarify a bit.. I sync the thumbnails separately (since one image can be used by several nodes)... I would like the initial thumbnail sync to save the files in the correct folder (not a temp one) and just point the imagefield to this file... That's what annoys me with field_file_save_file(), it saves a new file instead of just making a pointer.. Any advice?

  • Passing a paramter/object to a ruby unit/test before running it using TestRunner

    - by Nahir Khan
    I'm building a tool that automates a process then runs some tests on it's own results then goes to do some other stuff. In trying to clean up my code I have created a separate file that just has the test cases class. Now before I can run these tests, I have to pass the class a couple of parameters/objects before they can be run. Now the problem is that I can't seem to find a way to pass a parameter/object to the test class. Right now I am thinking to generate a Yaml file and read it in the test class but it feels "wrong" to use a temporary file for this. If anyone has a nicer solution that would be great! *********Edit******* Example Code of what I am doing right now: #!/usr/bin/ruby require 'test/unit/ui/console/testrunner' require 'yaml' require 'TS_SampleTestSuite' automatingSomething() importantInfo = getImportantInfo() File.open('filename.yml', 'w') do |f| f.puts importantInfo.to_yaml end Test::Unit::UI::Console::TestRunner.run(TS_SampleTestSuite) Now in the example above TS_SampleTestSuite needs importantInfo, so the first "test case" is a method that just reads in the information from the Yaml file filname.yml. I hope that clears up some confusion.
