• Avoiding cookies while requesting static content

  - by Abdel Olakara

  I just did an audit of one of my web application page (built using ASP.Net and running on development server) using Google chrome's developer tool. One particular warning caught my eyes: Serve static content from a cookieless domain (5)! Here is my screen shot (http://yfrog.com/7eauditresultp) as well. I would like to know is it possible to avoid cookies for these kind of requests. I see that there is no cookie requests for javascript files as well. I it possible to avoid cookies in the header for these files as well? and why didn't the browser attach cookies for javascript files and attach for CSS and image? Any thoughts and suggestions are welcome

• Maven test failure xml FileNotFoundException

  - by James

  My Maven build is failing on Hudson with a FileNotFoundException, I do not get the same failure through NetBeans. The FileNotFoundException is for some xml files in the same packages as my test classes themselves. It would appear these are not getting copied as part of the build in the same way the class files are. Do I have to add something to my POM for the xml files to be copied? If any more information is required please let me know, I wanted to keep the question short incase it was something simple.

• How can I bind a instance of a custom class to a WPF TreeListView without bugs?

  - by user327104

  First, from : http://blogs.msdn.com/atc_avalon_team/archive/2006/03/01/541206.aspx I get a nice TreeListView. I left the original classes (TreeListView, TreeListItemView, and LevelToIndentConverter) intact, the only code y have Added is on the XAML, here is it: <Style TargetType="{x:Type l:TreeListViewItem}"> .... </ControlTemplate.Triggers> <ControlTemplate.Resources> <HierarchicalDataTemplate DataType="{x:Type local:FileInfo}" ItemsSource="{Binding Childs}"> </HierarchicalDataTemplate> </ControlTemplate.Resources> </ControlTemplate> ... here is my custom class public class FileInfo { private List<FileInfo> childs; public FileInfo() { childs = new List<FileInfo>(); } public bool IsExpanded { get; set; } public bool IsSelected { get; set; } public List<FileInfo> Childs { get { return childs; } set { } } public string FileName { get; set; } public string Size { get; set; } } And before I use my custom class I remove all the items inside the treeListView1: <l:TreeListView> <l:TreeListView.Columns> <GridViewColumn Header="Name" CellTemplate="{StaticResource CellTemplate_Name}" /> <GridViewColumn Header="IsAbstract" DisplayMemberBinding="{Binding IsAbstract}" Width="60" /> <GridViewColumn Header="Namespace" DisplayMemberBinding="{Binding Namespace}" /> </l:TreeListView.Columns> </l:TreeListView> So finaly I add this code to bind a Instance of my class to the TreeListView: private void Window_Loaded(object sender,RoutedEventArgs e) { FileInfo root = new FileInfo() { FileName = "mis hojos", Size="asdf" }; root.Childs.Add(new FileInfo(){FileName="sub", Size="123456" }); treeListView1.Items.Add(root); root.Childs[0].Childs.Add(new FileInfo() { FileName = "asdf" }); root.Childs[0].IsExpanded = true; } So the bug is that the button to expand the elementes dont appear and when a node is expanded by doble click the child nodes dont look like child nodes. Please F1 F1 F1 F1 F1 F1 F1 F1.

• MS-Access nested DIR - check if a file exists elsewhere whilst looping through a folder

  - by David Carle

  I have used the DIR() command in Microsoft Access 2003 to loop through the files in folder A. This works fine, but I need to check if each file also exists in another location (folder B), and only process the file if it doesn't exist in folder B. The problem is that checking for the file existing in folder B also uses the DIR() function and this then resets or confuses the original one, with the result that no further files are found in folder A. Is there a way to check if a file exists without using DIR? Or, is there a way to have a separate instance of DIR? I suppose I could build a list of the files in folder A into an array and then process the entries in the array, but this seems rather 'clunky' Any suggestions for a better solution? Thanks

• Windows 8 permissions (CHMOD) with XAMPP

  - by Alex Gorcea

  While I know that CHMOD is impossible in Windows, I do have a problem with permissions. I'm running XAMPP on Windows 8 Release Preview and I'm trying to install ModenaCam. However, I get an error message which tells me that two files are not writable (they are 666) and they need to be 777. The permissions for the files are correct (full control for everyone, owner is everyone), but I can't get this thing to work! Any help would be greatly appreciated.

• R - Specifying colClasses in the read.csv

  - by Derek

  Hi, I am trying to specify the colClasses options in the read.csv function in R. In my data, the first column "time" is basically a character vector while the rest of the columns are numeric. data<-read.csv("test.csv" , comment.char="" , colClasses=c(time="character","numeric") , strip.white=FALSE) In the above command, I would want R to read in the "time" column as "character" and the as numeric. Although, the "data" variable did have the correct result after the command completed, R returned the following warnings. I am wondering how I could fix these warnings? Warning messages: 1: In read.table(file = file, header = header, sep = sep, quote = quote, : not all columns named in 'colClasses' exist 2: In tmp[i[i > 0L]] <- colClasses : number of items to replace is not a multiple of replacement length Thank in advance Derek

• Microsoft Windows 64-bit application development best practises installation folder.

  - by abmv

  My problem is that a vendor is providing me with a 64bit application (packed in a 64bit installer) but it goes and installs to the x86 (Program Files) Folder and he keeps telling me its OK but I want it to install in the Program Files directory; as the 32 bit version does that and scripts for the app are developed based on this assumption. Can someone direct me to the Microsoft recommended best practices for 64bit applications(links). Thanks in advance.

• SQL partial max

  - by Rob

  Struggling with the following SQL problem Assume a three dimensional table with entries (h,t,q) 1,A,20 1,A,10 1,B,5 2,A,10 2,B,3 2,B,8 3,C,50 4,A,10 etc. I would like to extract 1,30 2,11 3,50 etc. group by first element and then return the maximum q value of same type, i.e. for header number 2 there are 10 As and 11 Bs, so return 11 The "max" element (A in case 1, B in case 2 and C in case 3) is irrelevant, I just need to get out the header and that maximum value. This shouldnt be too tricky, but cant get it to work. Using MS Access, but can use SQL within.

• Windows 7 Homegroups not working?

  - by Jonas

  I've got a homegroup set up, and only the accounts/machines where the user and password is identical can see/share files. I thought the setting to let homegroup control the accounts would make that requirement unnecessary....am I missing something? To be clear: I can see the other machines/user accounts in my homegroup listing, but I can't see any of the files in their shared libraries.

• file upload in existing site with jquery and codeigniter

  - by Sam

  I am a new bee to ajax world. I am working on a site which uses jquery and codeigniter which processes big files like 2GB. It basically parses file and stores some extracted data from it, it uses ajax to show how far the files have been processed etc. Now I want to change the way we process files. I want to first store the file on server side and then start the processing. I evaluated upload class of codeigniter but looks like I cannot use it for this purpose as this class works with field_name and I could not find a way to make an ajax call to the upload class. My questions is : What would be suitable for my problem? Thanks in advance, Sam

• DVD playback with Windows Media Player 11 works fine, but when copied to HDD and then played back, t

  - by stakx

  I have several DVDs with short documentaries on it. Since the notebook I'm using (a Dell Latitude E6400) has only one DVD drive, and I might play back those short movies very often, I thought of copying them to the HDD and playing them back from there. However, I've run into a problem, namely stuttering audio. Problem description: When I play back these movies directly from DVD (with Windows Media Player 11 under Windows Vista), everything works fine. Smooth video, no significant audio problems (only the occasional click). But as soon as I copy any of these DVDs to the HDD and try to play them back from there (e.g. using the wmpdvd://drive/title/chapter?contentdir=path protocol, I get stuttering audio — audio playback sounds like a machine gun for a third of a second or so, approx. every 8 seconds. I have tried converting the VOB files from the DVD to another format (ie. ripping), but that resulted in a noticeable downgrade of picture quality. Therefore I thought it best to keep the files in their original format, if possible. Still, I suspect that the stuttering audio is due to some (de-)muxing problem, and that changing the file format might help. (After all, video playback is fine; therefore I don't think that the hardware is too slow for playback.) Only thing is, I don't know how to convert the VOB files to another Windows Media Player-compatible format without quality loss. I hope someone can help me, or give me further pointers on things I could try out to get HDD playback to work without the problem described. Some things I've tried so far, without any success: VOB2MPG, in order to convert the .vob file to a .mpg file. But that changes only the A/V container, not the content. No re-encoding takes place at all. Re-encoding with MPlayer/MEncoder. Lots of quality loss there, and I frankly haven't got the time to test all possible settings combinations available. Disabling all plug-ins, equalizers, etc. in Windows Media Player. Disabling all hardware acceleration on the audio playback device. Further info on the VOB files I'm trying to playback: The video format is MPEG ES, PAL 720x576 pixels @ 24/25 frames per second. The sound stream is uncompressed PCM, 16-bit stereo @ 48kHz. (Might it help if I somehow re-encoded the sound stream at a lower resolution, or as an MP3? If so, how would I do this without changing the video stream?) P.S.: I am limited to using Windows Media Player (11). (I previously tried MPlayer btw., but the video playback quality was surprisingly bad.)

• When does /tmp get cleared?

  - by John Lawrence Aspden

  I'm taking to putting various files in /tmp, and I wondered what the rules on deleting them are? I'm imagining it's different for different distributions, and I'm particularly interested in Ubuntu and Fedora desktop versions. But a nice general way of finding out would be a great thing. Even better would be a nice general way of controlling it! (Something like 'every day at 3 in the morning, delete any /tmp files older than 60 days, but don't clear the directory on reboot')

• Sourcing local .bashrc .vimrc without copy to remote machine

  - by David Strejc

  Does anyone have an idea or hack on how to source my local dotfiles (I will probably need more of them so this solution should work with many files) on remote machines without scp them to remote machine? Is something like scp .bashrc to /tmp folder on remote machine and then exporting BASHRC env variable the best solution? I need this because of our company policy and fast cloud servers deployment and redeployment and I don't want to touch .bashrc files on remote machine so my colleges are able to use their default env which doesn't suit me.

• Searching for known Team Development helper tools

  - by John

  Hello, My team is small, only two programmers.We both share one source ,but we live in different places.The problem is that Meanwhile I make changes on our project,the other team worker makes changes as well.It's very hard to write down every change,at least for us. When we decide we've made an important change,we contact each other sending the whole project's source. This is not good,because: The files sent from one do not contain the changes that the other worker has been working on meanwhile. We host the source on free servers,thus makes it possible for other to see the files.It will be VERY much better if only few(those that are changed) files are being uploaded rather than the whole project. My question: Are there any tools that could make our lives easier? Thanks in advance! EDIT: We use Delphi 2009.

• Office Automation Libraries

  - by Ian

  Some time ago I posted about a question about reading Excel files as a server process, to get around the tighter restrictions Microsoft have been applying on Office Automation. I now need to extend this, by finding methods/libraries to read other sorts of Office files in an automated way on a server. The applications I'm interested in are Word, Powerpoint, Project and to a lesser extent Word and Visio. I need to be able to support 97-2003 office files, and the newer open xml formats (e.g. xlsx, docx) at a very least. With regards to Word integration, I also need to be able to handle writing/reading RTF text. If anyone has any suggestions I'd be pleased to hear them. Thanks

• eclipse gcov plugin

  - by Taani

  I am using gcov plugin in Eclipse CDT + cygwin compiler & linker to find code coverage. I installed gcov plugin from http://svn.sourceforge.jp/svnroot/ginkgo/trunk/org.ginko.gcov.update/ location and follow the below link to get coverage of my .c file. I was able to create .gcno and .gcda files. But double clicking on those files, opens the files in eclipse editor. I could not find the gcov editor. Also I couldn't see any code coverage results in my .c file. What is the wrong with my procedure?

• data directory in automake

  - by Alex Farber

  I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only. How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.

• ExtJS Data Grid Column renderer to have multiple values

  - by Podlsk

  Hi, I am wondering if it is possible in ExtJS to have several values of the data source available to the renderer of the column. For example with the "Actions" column, the id is passed to the renderer. However I require both the user_id and id passed to the render. How may I do this? table_cols = [{ header: "User ID", width: 30, sortable: true, dataIndex: 'user_id' }, { header: "Actions", width: 60, sortable: false, dataIndex: 'id', renderer: function(val) { //IF USER ID MEETS A CONSTRAINT PRINT THE ID } }]; Thanks.

• Difference and correct usage for /tmp and /var/tmp

  - by David

  I haven't put much thought into this until now, but it seems odd that there is a /var/tmp and /tmp directories for most of the linux distro's I routinely use ( Ubuntu, Centos, Redhat ). Is there any semantic difference between the two, like when whoever designed the first file system layout, he or she thought "Not all tmp file's are created equal!" The only difference I've found for centos, is that /tmp routinely scrubs out files older then 240 hours while /var/tmp holds onto stale files for 720 hours.

• Excel 2010 Access to path is denied temp

  - by Chris Anderson

  I am using excel data reader to read data from an excel file. FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read); //1. Reading from a binary Excel file ('97-2003 format; *.xls) IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream); //2. Reading from a OpenXml Excel file (2007 format; *.xlsx) IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream); http://exceldatareader.codeplex.com/ This reads excel 1997-2003 format and excel 2007 format on my local machine and when we move it to our test server. However, when moved to production, it works for excel 97-2003 files, but when I try to read 2007 files I receive the following error: Access to the path 'C:\Documents and Settings\PORTALS03\ASPNET\LOCALS~1\Temp\TMP_Z129388041687919815' is denied. How is it possible that the 97-2003 excel file can be read but the 2007 files throw access is denied?

• Getting "on the wire" Size of Messages in WCF

  - by Mystagogue

  While I'm making SOAP or REST invocations to WCF, I'd like to have the channel stack on either end (client and server) record the on-the-wire size of the data received. So I'm guessing I need to add a custom behavior to the channel stack on either side. That is, on the server side I'd record the IP-header advertised size that was received. On the client side I'd record the IP-header advertised size that was returned from the server. But this presupposes that this information is visible to a custom WCF behavior at the channel stack level. Perhaps it is only visible at the level of ASP.NET (at a layer beneath WCF)? In short, does anyone have any further insight on if and how this information is accessible? I must qualify that this "size" data will be collected in a production environment, as part of regular business logic calls. This question is related to my earlier bandwidth question.

• Where can I find the gtk-builder-convert script?

  - by Marty

  I've built a small GUI app for work that uses some .glade files for pop-up windows. Recently, the ground beneath me was shifted - my environment was upgraded. Newer pyGTK versions require GTKBuilder and .xml files instead of Glade and .glade files and now my poor app is broken. I need to convert the .glade file to the newer .xml file. Problem is Glade-3 is not on our system, and I can't find gtk-builder-convert on the web. I've looked at the Gnome GIT Browser, don't know where to start looking or how to search it. Would anyone be kind enough to point me to the gtk-builder-convert python script?
