Flash video player doesn't play after rewriting a url

- by Joel

Hi! I recently started a new job working on a content management system. One of the jobs was to implement url rewriting, which i've done, but for some reason the URL rewriting has killed the ability to play flv files through FLVPlayer_Progressive. An example can be seen below: Working if you then follow the link on the menu and go to Campaigns It's a Living Thing you can see how it's not working when the url is being re-written. Below is the html for the object tag i'm setting within a gui editor on the admin side, everything on that end works also! <object height="160" width="284" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" id="FLVPlayer"> <param name="movie" value="/sitefiles/PeachSocial/flash/FLVPlayer_Progressive.swf"> <param name="salign" value="lt"> <param name="quality" value="high"> <param name="scale" value="noscale"> <param name="FlashVars" value="&MM_ComponentVersion=1&skinName=Clear_Skin_1&autoPlay=true&autoRewind=true&streamName=/sitefiles/PeachSocial/flash/dept_envrnmnt"> <embed src="/sitefiles/PeachSocial/flash/FLVPlayer_Progressive.swf" flashvars="&MM_ComponentVersion=1&skinName=Clear_Skin_1&autoPlay=true&autoRewind=true&streamName=/sitefiles/PeachSocial/flash/dept_envrnmnt" quality="high" scale="noscale" name="FLVPlayer" salign="LT" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" width="284" height="160"> </object> I would have thought giving the path the way i am would have taken it back to the server root and gone from there, but it doesn't seem to like it once the url rewriting happens. Anyways i'm outta ideas after a pretty frustrating day of trying to pass the thing absolute urls, relative paths and the like and am hoping a fresh set of eyes may help.

Overriding MSBuildExtensionsPath in the MSBuild task is flaky

- by Stuart Lange

This is already cross-posted at MS Connect: https://connect.microsoft.com/VisualStudio/feedback/details/560451 I am attempting to override the property $(MSBuildExtensionsPath) when building a solution containing a C# web application project via msbuild. I am doing this because a web application csproj file imports the file "$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets". This file is installed by Visual Studio to the standard $(MSBuildExtensionsPath) location (C:\Program Files\MSBuild). I would like to eliminate the dependency on this file being installed on the machine (I would like to keep my build servers as "clean" as possible). In order to do this, I would like to include the Microsoft.WebApplication.targets in source control with my project, and then override $(MSBuildExtensionsPath) so that the csproj will import this included version of Microsoft.WebApplication.targets. This approach allows me to remove the dependency without requiring me to manually modify the web application csproj file. This scheme works fine when I build my solution file from the command line, supplying the custom value of $(MSBuildExtensionsPath) at the command line to msbuild via the /p flag. However, if I attempt to build the solution using the MSBuild task in a custom msbuild project file (overriding MSBuildExtensionsPath using the "Properties" attribute), it fails because the web app csproj file is attempting to import the Microsoft.WebApplication.targets from the "standard" Microsoft.WebApplication.targets location (C:\Program Files\MSBuild). Notably, if I run msbuild using the "Exec" task in my custom project file, it works. Even more notably, the FIRST time I run the build using the "MSBuild" task AFTER I have run the build using the "EXEC" task (or directly from the command line), the build works. Has anyone seen behavior like this before? Am I crazy? Is anyone aware of the root cause of this problem, a possible workaround, or whether this is a legitimate bug in MSBuild?

Graph navigation problem

- by affan

I have graph of components and relation between them. User open graph and want to navigate through the graph base on his choice. He start with root node and click expand button which reveal new component that is related to current component. The problem is with when use decide to collapse a node. I have to choose a sub-tree to hide and at same time leave graph in consistent state so that there is no expanded node with missing relation to another node in graph. Now in case of cyclic/loop between component i have difficult of choosing sub-tree. For simplicity i choose the order in which they were expanded. So if a A expand into B and C collapse A will hide the nodes and edge that it has created. Now consider flowing scenario. [-] mean expanded state and [+] mean not yet expanded. A is expanded to reveal B and C. And then B is expanded to reveal D. C is expanded which create a link between C and exiting node D and also create node E. Now user decide to collapse B. Since by order of expansion D is child of B it will collapse and hide D. This leave graph in inconsistent state as C is expanded with edge to D but D is not anymore there if i remove CD edge it will still be inconsistent. If i collapse C. And E is again a cyclic link e.g to B will produce the same problem. /-----B[-]-----\ A[-] D[+] \-----C[-]-----/ \ E[+] So guys any idea how can i solve this problem. User need to navigate through graph and should be able to collapse but i am stuck with problem of cyclic nodes in which case any of node in loop if collapse will leave graph in inconsistent state.

@OneToMany and composite primary keys?

- by Kris Pruden

Hi, I'm using Hibernate with annotations (in spring), and I have an object which has an ordered, many-to-one relationship which a child object which has a composite primary key, one component of which is a foreign key back to the id of the parent object. The structure looks something like this: +=============+ +================+ | ParentObj | | ObjectChild | +-------------+ 1 0..* +----------------+ | id (pk) |-----------------| parentId | | ... | | name | +=============+ | pos | | ... | +================+ I've tried a variety of combinations of annotations, none of which seem to work. This is the closest I've been able to come up with: @Entity public class ParentObject { @Column(nullable=false, updatable=false) private String id; @OneToMany(mappedBy="object", fetch=FetchType.EAGER) @IndexColumn(name = "pos", base=0) private List<ObjectChild> attrs; ... } @Entity public class ChildObject { @Embeddable public static class Pk implements Serializable { @Column(nullable=false, updatable=false) private String objectId; @Column(nullable=false, updatable=false) private String name; @Column(nullable=false, updatable=false) private int pos; ... } @EmbeddedId private Pk pk; @ManyToOne @JoinColumn(name="parentId") private ParentObject parent; ... } I arrived at this after a long bout of experimentation in which most of my other attempts yielded entities which hibernate couldn't even load for various reasons. The error I get when I try to read one of these objects (they seem to save OK), I get an error of this form: org.hibernate.exception.SQLGrammarException: could not initialize a collection: ... And the root cause is this: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'attrs0_.id' in 'field list' I'm sure I'm missing something simple, but the documentation is not clear on this matter, and I haven't been able to find any examples of this anywhere else. Thanks!

Turning off hibernate logging console output

I'm using hibernate 3 and want to stop it from dumping all the startup messages to the console. I tried commenting out the stdout lines in log4j.properties but no luck. I've pasted my log file below.

Python web scraping involving HTML tags with attributes

- by rohanbk

I'm trying to make a web scraper that will parse a web-page of publications and extract the authors. The skeletal structure of the web-page is the following: <html> <body> <div id="container"> <div id="contents"> <table> <tbody> <tr> <td class="author">####I want whatever is located here ###</td> </tr> </tbody> </table> </div> </div> </body> </html> I've been trying to use BeautifulSoup and lxml thus far to accomplish this task, but I'm not sure how to handle the two div tags and td tag because they have attributes. In addition to this, I'm not sure whether I should rely more on BeautifulSoup or lxml or a combination of both. What should I do? At the moment, my code looks like what is below: import re import urllib2,sys import lxml from lxml import etree from lxml.html.soupparser import fromstring from lxml.etree import tostring from lxml.cssselect import CSSSelector from BeautifulSoup import BeautifulSoup, NavigableString address='http://www.example.com/' html = urllib2.urlopen(address).read() soup = BeautifulSoup(html) html=soup.prettify() html=html.replace('&nbsp', '&#160') html=html.replace('&iacute','&#237') root=fromstring(html) I realize that a lot of the import statements may be redundant, but I just copied whatever I currently had in more source file. EDIT: I suppose that I didn't make this quite clear, but I have multiple tags in page that I want to scrape.

One object in jTemplate?

- by Dejan.S

Hi I'm using jTemplate for the first time. I been reading and it's not that hard to use it BUT what I can not figure out and find any thing on is how to work with one object, all the examples I find are a list of objects. My situation is I need to work with one object only. How can I do that? I mean How to work with the data in the jTemplate like this example but one only. <script type="text/html" id="TemplateResultsTable"> {#template MAIN} <table cellpadding="10" cellspacing="0"> <tr> <th>Artist</th> <th>Company</th> <th>Title</th> <th>Price</th> </tr> {#foreach $T.d as CD} {#include ROW root=$T.CD} {#/for} </table> {#/template MAIN} {#template ROW} <tr class="{#cycle values=['','evenRow']}"> <td>{$T.Artist}</td> <td>{$T.Company}</td> <td>{$T.Title}</td> <td>{$T.Price}</td> </tr> {#/template ROW} </script>

Loading data from a dictionary of dictionaries into an array in Objective C for an iphone app

- by Kat

I have a UINavigationController consisting of a tableview I want to load some data into. I have a dictionary plist containing Dictionaries for each Train Line which in turn have dictionaries for each station with the relevant information along with one string lineName. I need to collect the station Names keys and add them to an array to populate my table (This is working). The line names are stored as a string in my lines dictionary with the key being "lineName" Root->| | |->TrainLine1(Dictionary)->| | |-> lineName (String) | |-> Station1 (Dictionary) | |-> Station2 (Dictionary) | | |->TrainLine2(Dictionary)->| | |-> lineName (String) | |-> Station1 (Dictionary) | |-> Station2 (Dictionary) Am I going about this the wrong way? Should I reorganise my plist? The code below crashes the app. - (void)viewDidLoad { self.title = @"Train Lines"; NSString *path = [[NSBundle mainBundle] pathForResource:@"lineDetails" ofType:@"plist"]; NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:path]; NSMutableArray *array = [[NSMutableArray alloc] init]; NSMutableArray *lineNameArray = [[NSMutableArray alloc] init]; NSString *key; for (key in dictionary) { NSMutableDictionary *secondDictionary = [NSDictionary dictionaryWithDictionary:[dictionary valueForKey:key]]; [lineNameArray addObject:key]; NSLog(@"Adding this in array:%@", key); [array addObject:[secondDictionary objectForKey:kLineNameKey]]; } self.trainLines = array; self.trainLineKeys = lineNameArray; NSLog(@"Array contents:%@", self.trainLineKeys); [lineNameArray release]; [array release]; [dictionary release]; [super viewDidLoad]; }

Oracle T4CPreparedStatement memory leaks?

- by Jay

A little background on the application that I am gonna talk about in the next few lines: XYZ is a data masking workbench eclipse RCP application: You give it a source table column, and a target table column, it would apply a trasformation (encryption/shuffling/etc) and copy the row data from source table to target table. Now, when I mask n tables at a time, n threads are launched by this app. Here is the issue: I have run into a production issue on first roll out of the above said app. Unfortunately, I don't have any logs to get to the root. However, I tried to run this app in test region and do a stress test. When I collected .hprof files and ran 'em through an analyzer (yourKit), I noticed that objects of oracle.jdbc.driver.T4CPreparedStatement was retaining heap. The analysis also tells me that one of my classes is holding a reference to this preparedstatement object and thereby, n threads have n such objects. T4CPreparedStatement seemed to have character arrays: lastBoundChars and bindChars each of size char[300000]. So, I researched a bit (google!), obtained ojdbc6.jar and tried decompiling T4CPreparedStatement. I see that T4CPreparedStatement extends OraclePreparedStatement, which dynamically manages array size of lastBoundChars and bindChars. So, my questions here are: Have you ever run into an issue like this? Do you know the significance of lastBoundChars / bindChars? I am new to profiling, so do you think I am not doing it correct? (I also ran the hprofs through MAT - and this was the main identified issue - so, I don't really think I could be wrong?) I have found something similar on the web here: http://forums.oracle.com/forums/thread.jspa?messageID=2860681 Appreciate your suggestions / advice.

Setup.exe files downloading without cab files over poor connections

- by Colin

We have customers who are trying to download a setup.exe file over mobile connections that appear to be very slow. They have reported that when they click on the downloaded setup.exe, the install wizard starts up, but part way through the wizard they get an error message indicating that a cab file is corrupt or missing. They couriered a problem tablet to us, and we downloaded the file without a problem but I could replicate the problem by using https to download the file (https is normally used to access the rest of the site, although it is not necessary for the download). When I did this the downloaded file was 2.8MB. It should be 8MB. I don't think that https is the root cause of the problem because I can see the download link in the browser history using http, so I know the customer tried to download using http. I think that the issue is that the poor connection is preventing a complete download, but the browser is acting as if it is complete. Is there a way to ensure the file is downloaded fully, or not at all? Why does the browser not indicate that the download is incomplete?

How to open a document using an application launched via NSTask?

- by zneak

Hello world, I've grown tired of the built-in open Mac OS X command, mostly because it runs programs with your actual user ID instead of the effective user ID; this results in the fact sudo open Foo opens Foo with its associated application with your account instead of the root account, and it annoys me. So I decided to make some kind of replacement. So far I've been successful: I can open any program under the open -a or open -b fashion, and support optionally waiting. I'm using NSTask for that purpose. However, I'd like to be able to open documents too. As far as I can see, you need to use NSWorkspace for that, but using NSWorkspace to launch programs results in them being launched with your account's credentials instead of your command line program's credentials. Which is precisely what the default open tool does, and precisely what I don't want. So, how can I have a program request that another program opens a document without using NSWorkspace? From the NSTask object, I can have the process ID, but that's about it.

haskell: a data structure for storing ascending integers with a very fast lookup

- by valya

Hello! (This question is related to my previous question, or rather to my answer to it.) I want to store all qubes of natural numbers in a structure and look up specific integers to see if they are perfect cubes. For example, cubes = map (\x -> x*x*x) [1..] is_cube n = n == (head $ dropWhile (<n) cubes) It is much faster than calculating the cube root, but It has complexity of O(n^(1/3)) (am I right?). I think, using a more complex data structure would be better. For example, in C I could store a length of an already generated array (not list - for faster indexing) and do a binary search. It would be O(log n) with lower ?oefficient than in another answer to that question. The problem is, I can't express it in Haskell (and I don't think I should). Or I can use a hash function (like mod). But I think it would be much more memory consuming to have several lists (or a list of lists), and it won't lower the complexity of lookup (still O(n^(1/3))), only a coefficient. I thought about a kind of a tree, but without any clever ideas (sadly I've never studied CS). I think, the fact that all integers are ascending will make my tree ill-balanced for lookups. And I'm pretty sure this fact about ascending integers can be a great advantage for lookups, but I don't know how to use it properly (see my first solution which I can't express in Haskell).

wcf callback exception after updating to .net 4.0

- by James

I have a wcf service that uses callbacks with DualHttpBindings. The service pushes back a datatable of search results the client (for a long running search) as it finds them. This worked fine in .Net 3.5. Since I updated to .Net 4.0, it bombs out with a System.Runtime.FatalException that actually kills the IIS worker process. I have no idea how to even go about starting to fix this. Any recommendations appreciated. The info from the resulting event log is pasted below.

HTML include statement

- by iMaster

I'm just trying to do a simple include statement in HTML. I have no clue why its not working. My file setup is basically index.php in the root and then a file called "includes" with a file "header.html" inside. So here's my code: <!DOCTYPE html> <html lang="en"> <html> <head> <title>Title</title> <link type="text/css" href="style/style.css" media="screen" rel="stylesheet"> <script src="scripts/jquery.js" type="text/javascript"></script> <script src="scripts/code.js" type="text/javascript"></script> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> </head> <body> <div id="wrapper">  ...blah blah blah </div> </body> </html> I've verified that the file is there so I'm not sure what else the problem could be. Thanks!

How does VS 2005 provide history across all TFS Team Projects when tf.exe cannot?

- by AakashM

In Visual Studio 2005, in the TFS Source Control Explorer, these is a top-level node for the TFS Server itself, with a child node for each Team Project. Right-clicking either the server node or the node for a Team Project gives a context menu on which there is a View History item. Selecting this gives you a History window showing the last 200 or so changesets, either for the specific Team Project chosen, or across all Team Projects. It is this history across all Team Projects that I am wondering about. The command-line tf.exe history command provides (as I understand it) basically the same functionality as is provided by the VS TFS Source Control plug-in. But I cannot work out how to get tf.exe history to provide this across-all-Team-Projects history. At a command line, supposing I have C:\ mapped as the root of my workspace, and Foo, Bar, and Baz as Team Projects, I can do C:\> tf history Foo /recursive /stopafter:200 to get the last 200 changesets that affected Team Project Foo; or from within a Team Project folder C:\Bar> tf history *.* /recursive /stopafter:200 which does the same thing for Team Project Bar - note that the wildcard *.* is allowed here. However, none of these work (each gives the error message shown): C:\> tf history /recursive /stopafter:200 The history command takes exactly one item C:\> tf history *.* /recursive /stopafter:200 Unable to determine the source control server C:\> tf history *.* /server:servername /recursive /stopafter:200 Unable to determine the workspace I don't see an option in the docs for tf for specifying a workspace; it seems to only want to determine it from the current folder. So what is VS 2005 doing? Is it internally doing a history on each Team Project in turn and then sticking the results together?? note also that I have tried with Power Tools; tfpt history from the command line gives exactly the same error messages seen here

Automatically add links to class source files under a specified directory of another project in Visu

- by Binary255

I want to share some class source files between two projects in Visual Studio 2008. I can't create a project for the common parts and reference it (see my comment if you are curious to why). I've managed to share some source files, but it could be a lot more neat. I've created a test solution called Commonality. The Solution Explorer of the Commonality solution which contains project One and Two: What I like: All class files under the Common folder of project One are automatically added to project Two by linking. It's mostly the same as if I would have chosen Add / Existing Item... : Add As Link on each new class source file. It's clear that these files have been linked in. The shortcut arrow symbol is marking each file icon. What I do not like: The file and folder tree structure under Common of project One isn't included. It's all flat. The linked source files are shown under the project root of project Two. It would look much less cluttered if they were located under Common like in project One. The file tree structure of the Commonality solution which contains project One and Two: $ tree /F /A Folder PATH listing for volume Cystem Volume serial number is 0713370 1337:F6A4 C:. | Commonality.sln | +---One | | One.cs | | One.csproj | | | +---bin | | \---Debug | | One.vshost.exe | | One.vshost.exe.manifest | | | +---Common | | | Common.cs | | | CommonTwo.cs | | | | | \---SubCommon | | CommonThree.cs | | | +---obj | | \---Debug | | +---Refactor | | \---TempPE | \---Properties | AssemblyInfo.cs | \---Two | Two.cs | Two.csproj | Two.csproj.user | Two.csproj~ | +---bin | \---Debug +---obj | \---Debug | +---Refactor | \---TempPE \---Properties AssemblyInfo.cs And the relevant part of project Two's project file Two.csproj: <ItemGroup> <Compile Include="..\One\Common\**\*.cs"> </Compile> <Compile Include="Two.cs" /> <Compile Include="Properties\AssemblyInfo.cs" /> </ItemGroup> How do I address what I do not like, while keeping what I like?

Unresolved external symbol - MySQL API C++

- by Zack_074

Hey I've had nonstop problems with SQL. I'm trying to get some experience because I know it's a vital part of the industry. I got it working with C#, but now I'm working on connecting to a database in c++. I have the project properly linked and what not. Here's my code and the errors I'm getting. #include "stdafx.h" #include <mysql.h> #include <iostream> MYSQL mysql; MYSQL_RES result; using namespace std; int _tmain(int argc, _TCHAR* argv[]) { mysql_init(&mysql); if(!mysql_real_connect(&mysql, "localhost", "root", "angel552002", "MyDatabse", 0, NULL, 0)) { printf("Failed to connect"); } return 0; } and the errors: Error 1 error LNK2001: unresolved external symbol _mysql_real_connect@32 c:\Users\Zack-074\documents\visual studio 2010\Projects\MySql\MySql\MySql.obj Error 2 error LNK2001: unresolved external symbol _mysql_init@4 c:\Users\Zack-074\documents\visual studio 2010\Projects\MySql\MySql\MySql.obj Error 3 error LNK1120: 2 unresolved externals c:\users\zack-074\documents\visual studio 2010\Projects\MySql\Debug\MySql.exe 1 I really appreciate the help.

Codeigniter: Base_url doesn't seem to be working

- by Dwayne

I have developed a simple site that fetches tweets from the Twitter public timeline, caches them for 60 seconds and so on. I have recently moved hosts from Hostgator to Mediatemple and my site was previously working fine on Hostgator. My application doesn't use a database connection, nor does it use any form of flat-file database either. Tweets are cached in an XML file stored in the root directory, not that most of that is important. The url helper is being included as can be seen below (this is my helpers line from autoload.php): $autoload['helper'] = array('url'); I have also removed my index.php file from the URL using .htaccess directives and once again this was previously working on Hostgator (see my .htaccess code below): RewriteEngine On RewriteRule ^(application) - [F,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php/$0 [PT,L] In my home.php view file which is in the views folder inside of application, I am using the function base_url() which was previously working on Hostgator inside of my view files and appending it a base href value in my header: <base href="<?php echo base_url(); ?>" /> Here is what my base_url value looks like in the config.php file: $config['base_url'] = "http://threetune.com/"; Although what appears to be happening is that the base_url is not to be seen at all. It doesn't appear to be echoing out the value of base_url as it appears to be empty for some reason. What makes things weirder is that I have a link in another view file called 'fetch.php' and for some reason it appears to be stripping out the value (XSS filtering is off): <a href="threetune/show"><img src="assets/images/cookie.jpg" /></a> The threetune/show part is not to be seen and I only see an empty href value like this <a href=""><img src="assets/images/cookie.jpg" /></a> Can anyone possibly see anything wrong that I may have done, some kind of Mediatemple server limitation or PHP.ini flag that needs to be set? Thank you and I hope I was descriptive enough.

IntelliJ IDEA plugin development: Get classes VirtualFile (or paths) for a specific source VirtualFi

- by Ran Biron

Hi all. This is a cross-post from http://www.jetbrains.net/devnet/message/5264436#5264436 - I failed to get any answer on that forum for two weeks now, so I'm re-asking it here (please don't flame). This question refers to plugin development for the IntelliJ IDEA IDE, specifically targeting java development: Is there any API to get the list of .class files for given source file? I'm trying to write a plugin that creates a binary patch jar based on a changelist. I've managed to get the changelist and, from it, a list of source files (VirtualFile). Now I'm trying to get the compiled class files for these source files (I don't mind preforming a "make" or relying on the previous compile output). I've played a bit with ProjectFileIndex but could only find the classes root. I'd hate to do a "dumb" path-based search because inner classes (and inner anonymous classes) would make it difficult to get correctly. Is there such an API? Or am I doomed to parse the paths? Thanks, Ran.
