• Accessing an RSS feed in Flex, works when run from Flash Builder 4, but not when the project is onli

  - by ben

  Hey guys, In my Flex 4 app, I access an RSS feed (I'm using http://news.ycombinator.com/rss as a dummy). It works okay when I run it from Flash Builder 4, but if I export the project and upload it, I get the following error when it tries to load the RSS feed: Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: my_website_url cannot load data from http://news.ycombinator.com/rss. What could be causing this error? Shouldn't RSS be able to be accessed from anywhere? Thanks for reading.

• view is not rendered when returning ModelAndView

  - by adancu

  Hi, I have the following problem. I need to export a PDF in a controller The code below, where I return a View, works as expected. @RequestMapping(method = RequestMethod.GET) public View exportReport( @RequestParam(value = "userName", required = true) String userName, @RequestParam(value = "startDate", required = true) Date startDate, @RequestParam(value = "endDate", required = true) Date endDate) { /////////////////////////////////////////// return new TimeSheetReportPdfView(); } The problem occurs if I change the method to return a ModelAndView: @RequestMapping(method = RequestMethod.GET) public ModelAndView exportReport( @RequestParam(value = "userName", required = true) String userName, @RequestParam(value = "startDate", required = true) Date startDate, @RequestParam(value = "endDate", required = true) Date endDate) { /////////////////////////////////////////// return new ModelAndView(new TimeSheetReportPdfView(), model); } Now, the PDF is not exported, all I get is a blank page and nothing in the logs. Any help appreciated. Thanks.

• Force Python to be 32 bit on OS X Lion

  - by sciencectn

  I'm trying to use CPLEX within Python on Mac OS 10.7.5. CPLEX appears to only support a 32 bit python. I'm using this in a python shell to check if it's 32 bit: import sys,platform; print platform.architecture()[0], sys.maxsize > 2**32 I've tried these 2 commands as suggested in man 1 python, but neither seem to force 32 bit: export VERSIONER_PYTHON_PREFER_32_BIT=yes defaults write com.apple.versioner.python Prefer-32-Bit -bool yes The only thing that seems to work is this: arch -i386 python However, if I run a script using arch which calls other scripts, they all seem to start up in 64 bit mode. Is there another system wide variable to force it into 32 bit mode?

• stting environment variables in powershell by calling python script that prints $env:myVar=myvalue

  - by leeg

  I have some legacy python scripts that manage my shell environment for all the programs and plugins I am running on Linux (bash) and windows (cmd.exe). I want to port this to powershell. How do I set environment variables in powershell by calling python script that prints $env:myVar=myvalue and causes my environment variable to persist in the powershell. In Bash I can use a bash function to call my python script which prints export var=value to stdout and the function will set the environment variables in my shell. This will also work in windows cmd shell by calling a .bat file. I cannot figure out how to do this in powershell. I think it should be something like this: setvar.ps1: function SETVAR {c:\python26\python.exe varconfig.py } varconfig.py: import sys print >> sys.stdout, '$env:myVar=foo'

• How can I replicate the functionality of the Flash Builder's release tool in ant?

  - by Chris R

  I want to build an ant script that does exactly the same compilation actions on a Flash Builder 4 (Gumbo) project as the Project->Export Release Build... menu item does. My ant-fu is reasonably strong, that's not the issue, but rather I'm not sure exactly what that entry is doing. Some details: I'll be using the 3.x SDK (say, 3.2 for the sake of specificity) to build this. I'll be building on a Mac, and I can happily use ant, make, or some weird shell script stuff if that's the way you roll. Any useful optimizations you can suggest will be welcome. The project contains a few assets, MXML and actionscript source, and a couple of .swcs that are built into the project (not RSL'd) Can someone provide an ant build.xml or makefle that they use to build a release .swf file from a similar Flex project?

• Is there a reasonable way to attach new path to PATH in bashrc?

  - by Ripley

  Guys I constantly need to attach new paths to the PATH environment variable in .bashrc, like below: export PATH=/usr/local/bin:$PATH Then to make it take effect, I always do 'source ~/.bashrc' or '. ~/.bashrc', while I found one shortcoming of doing so which make me uncomfortable. If I keep doing so, the PATH will getting longer and longer with many duplicated entries, for example in the previous command, if I source it twice, the value of PATH will be PATH=/usr/local/bin:/usr/local/bin:/usr/local/bin:$PATH(<-the original path). Is there a more decent way to attach new path to PATH in bashrc without making it ugly?

• Exporting DataTable using FileHelpers

  - by Dat

  I want to export the contents of a DataTable to a text delimited file using FileHelpers, is this possible? Here is what I have so far: // dt is a DataTable with Rows in it DelimitedClassBuilder cb = new DelimitedClassBuilder("MyClassName", "|", dt); Type t = cb.CreateRecordClass(); FileHelperEngine engine = new FileHelperEngine(t); I have to convert the contents of dt to an array of type "MyClassName" but I'm not sure how to do that? I know there is a FileDataLink class but none of them work with DataTable (or even a DataSet).

• How to retrieve files/documents that are not found on the web server machine.

  - by jhorton

  I am trying to create an export feature for a user to be able to download documents into a zip file. I have the feature working when the files are located on my local and I can use an absolute path on my local. But after talking to the infrastructure team, I found out that the documents are not stored on the same machine as the web server but located at a server farm located off site. I can query the database which gives me a file path. But the path is more of a relative path. So can anyone help me understand how to use FileInfo with getting files from another machine. I believe the infrastructure team said there is a virtual drive set up to the outside server. Am I able to use a virtual path some how? Thanks.

• How to determine path to project folder in .Net?

  - by paul

  I have a project folder called XSL which contains xsl files used for transforming xml. I use the following code to fetch an xsl file: string html = @"c:\temp\export.html"; XslCompiledTransform transform = new XslCompiledTransform(); Uri uri = new Uri(@"XSL\ToHtml.xsl", UriKind.Relative); transform.Transform(CurrentXmlFile, html); System.Diagnostics.Process.Start(html); This works ok when debugging but when I deploy using clickonce and install it, I get an error - 'Could not find part of the path {my user path}\XSL\ToHtml.xsl' What must I do to correctly reference this path?

• C#: Changing the order of columns when binding DataTable to a GridView

  - by Nir

  How is it possible to change the displayed order of columns from a DataTable? For example, dataTable "dt" contains two columns "a" and "b". I bind it to a GridView like this: gridView.DataSource = dt; gridView.DataBind(); But I'd like the GridView to display "b" first (leftmost). Important point: I'm using this to export to Excel and there's no actual output to screen, using: HtmlTextWriter htw = new HtmlTextWriter(sw); gridView.RenderControl(htw); Thanks!

• Can I Import an updated structure into a MySQL table without losing its current content?

  - by Udi Wertheimer

  We use MySQL tables to which we add new fields from time to time as our product evolves. I'm looking for a way to export the structure of the table from one copy of the db, to another, without erasing the contents of the table I'm importing to. For example say I have copies A and B of a table, and I add fields X,Y,Z to table A. Is there a way to copy the changed structure (fields X,Y,Z) to table B while keeping its content intact? I tried to use mysqldump, but it seems I can only copy the whole table with its content, overriding the old one, or I can use the "-d" flag to avoid copying data (dumping structure only), but this will create an empty table when imported, again overriding old data. Is there any way to do what I need with mysqldump, or some other tool?

• avmutablecomposition insertEmptyTimeRange

  - by smartfaceweb

  I have created an avmutablecomposition and tried to use insertEmptyTimeRange to generate 1 minute of silence. This doesn't appear to be working. I have also tried creating an avmutablecompositiontrack using addMutableTrackWithMediaType:preferredTrackID: and then insertEmptyTimeRange on the track and still no success. To give some background on my app, I allow users to add audio samples a timeline and then playback or export and this is working really well using the av classes. The problem is that I need to make sure that the audio is exactly 1 min (for example). Regardless of the info about my specific app above, is it possible to insert an empty time range into a comp or comptrack?

• Paging in SQL Server problems

  I have searched for paging in SQL Server. I found most of the solution look like that What is the best way to paginate results in SQL Server But it don't meet my expectation. Here is my situation: I work on JasperReport, for that: to export the report I just need pass the any Select query into the template, it will auto generated out the report EX : I have a select query like this: Select * from table A I don't know any column names in table A. So I can't use Select ROW_NUMBER() Over (Order By columsName) And I also don't want it order by any columns. Anyone can help me do it? PS: In Oracle , it have rownum very helpful in this case. Select * from tableA where rownum > 100 and rownum <200 Paging with Oracle

• Is there a reason why SSIS significantly slows down after a few minutes?

  - by Mark

  I'm running a fairly substantial SSIS package against SQL 2008 - and I'm getting the same results both in my dev environment (Win7-x64 + SQL-x64-Developer) and the production environment (Server 2008 x64 + SQL Std x64). The symptom is that initial data loading screams at between 50K - 500K records per second, but after a few minutes the speed drops off dramatically and eventually crawls embarrasingly slowly. The database is in Simple recovery model, the target tables are empty, and all of the prerequisites for minimally logged bulk inserts are being met. The data flow is a simple load from a RAW input file to a schema-matched table (i.e. no complex transforms of data, no sorting, no lookups, no SCDs, etc.) The problem has the following qualities and resiliences: Problem persists no matter what the target table is. RAM usage is lowish (45%) - there's plenty of spare RAM available for SSIS buffers or SQL Server to use. Perfmon shows buffers are not spooling, disk response times are normal, disk availability is high. CPU usage is low (hovers around 25% shared between sqlserver.exe and DtsDebugHost.exe) Disk activity primarily on TempDB.mdf, but I/O is very low (< 600 Kb/s) OLE DB destination and SQL Server Destination both exhibit this problem. To sum it up, I expect either disk, CPU or RAM to be exhausted before the package slows down, but instead its as if the SSIS package is taking an afternoon nap. SQL server remains responsive to other queries, and I can't find any performance counters or logged events that betray the cause of the problem. I'll gratefully reward any reasonable answers / suggestions.

• phpmyadmin and the database

  - by Jonathan

  Not sure I fully understand what phpmyadmin does. I created a database in phpmyadmin, and would now like to start accessing the data in it from php. However I have no idea where the database is? Should I export in the phpmyadmin software? I tried that but it came up with a .sql file which can be opened in notepad and contains the SQL statements used to create the datbase and the one table inside. Basically that doesn't look like a database to me.

• ssrs column groups disable multiple columns

  - by DKS

  I'm using ASP.NET 4.0 Visual Studio 2010 RC version Sql Server Report Services (SSRS) ReportViewer and are aware that columns only display on PDF export - not the preview. I want to use a matrix embedded in a table on a page that has multiple columns. I've done some testing and frustratingly found that if you have a tablix with at least one grouped column (even if there is only one displayed matrix-like column group) the columns seem to be disabled. Once I remove the tablix with a grouped column from the tablix from the report the report does multiple-columns. Does anyone know a way around this?

• Anova test in the loop and outputing the p-value in separate column

  Once again I'm trying to get an answer. I am already stuck for like 5h with that so that's why I keep trying to get an answer. That's my data: id Sequence variable value 75 AAAAGAAAVANQGKK BiotinControl1_2 3893050.50 192 AAAAGAAAVANQGKK BiotinControl1_2 900604.61 3770 AAFTKLDQVWGSE BiotinControl1_2 90008.14 The code which I am trying to use to calculate the p-value: My Code: tbl_anv <- tbl_all_onlyK[,c("id", "BiotinControl1_2", "BiotinControl2", "BiotinControl3", "BiotinTreatment1_2", "BiotinTreatment2", "BiotinTreatment3", "Sequence")] tbl_reo <- melt(tbl_anv, measure.vars=2:7) set.seed(1) vars <- c("id", "BiotinControl1_2", "BiotinControl2", "BiotinControl3", "BiotinTreatment1_2", "BiotinTreatment2", "BiotinTreatment3", "Sequence") tbl_reo <- as.data.frame(tbl_reo) by(tbl_reo,tbl_reo$Sequence,function(x){ anova(lm(value ~ variable, data = x))$"Pr(>F)"[1] }) An error ocurs: There were 50 or more warnings (use warnings() to see the first 50) Anyway, how can I do that and export the p-value in the separate column. That's what I tried to do on my own: aov_test <- by(tbl_reo,tbl_reo$Sequence,function(x){ anova(lm(value ~ variable, data = x))$"Pr(>F)"[1] }) tbl_reo[,5] <- aov.test[[1]]$'Pr(>F)'[1]

• How do I change the JAVA_HOME for ant?

  - by Eugene M

  I'm doing java work on a class server where I don't have root. Whenever I try to compile using ant, it points to the wrong directory (/usr/tomcat instead of /usr/tomcat/jre ). One of the things we were told to do when setting up our user accounts was to add export JAVA_HOME=/usr/tomcat/jre to the .bashrc file. I don't know if that was supposed to take care of the problem but it doesn't seem to. So, how can I change the JAVA_HOME property for ant but only for when I run ant? EDIT: echo $JAVA_HOME points to /usr/tomcat/jre echo $JAVA_HOME\bin points to /usr/tomcat/jrebin The problem is when I normally run ant I get this error: Unable to locate tools.jar. Expected to find it in /usr/tomcat/lib/tools.jar Buildfile: build.xml compile: [javac] Compiling 1 source file to /home/ejm244/build/classes BUILD FAILED /home/ejm244/build.xml:9: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath.

• Python and sqlite3 - importing and exporting databases

  - by JPC

  I'm trying to write a script to import a database file. I wrote the script to export the file like so: import sqlite3 con = sqlite3.connect('../sqlite.db') with open('../dump.sql', 'w') as f: for line in con.iterdump(): f.write('%s\n' % line) Now I want to be able to import that database. I tried: import sqlite3 con = sqlite3.connect('../sqlite.db') f = open('../dump.sql','r') str = f.read() con.execute(str) but I'm not allowed to execute more than one statement. Is there a way to get it to run a .sql script directly?

• Optimizing simple search script in PowerShell

  - by cc0

  I need to create a script to search through just below a million files of text, code, etc. to find matches and then output all hits on a particular string pattern to a CSV file. So far I made this; $location = 'C:\Work*' $arr = "foo", "bar" #Where "foo" and "bar" are string patterns I want to search for (separately) for($i=0;$i -lt $arr.length; $i++) { Get-ChildItem $location -recurse | select-string -pattern $($arr[$i]) | select-object Path | Export-Csv "C:\Work\Results\$($arr[$i]).txt" } This returns to me a CSV file named "foo.txt" with a list of all files with the word "foo" in it, and a file named "bar.txt" with a list of all files containing the word "bar". Is there any way anyone can think of to optimize this script to make it work faster? Or ideas on how to make an entirely different, but equivalent script that just works faster? All input appreciated!
