• Streaming data to the browser as a file of unknown size

  - by Sir Psycho

  I have some data which is queried from the database and I'd like to send it to the client as a csv file. The file size varies each time due to the fact that the DB data returned can be of any size. Instead of saving this file to the hard disk, I'd like to send it to the browser at the same time it's being processed into a CSV by my algorithm. Response.Write seems useless. For some reason, the file download dialog is only displayed once my processing is finished. This seems odd as I'm writting all my output to the Response.Output stream. I have downloaded files on the web before where the filesize is not known and the browser just keeps on downloading. Is there any way to achieve this? The following stackoverflow thread did not offer any good advise. http://stackoverflow.com/questions/873995/asp-net-downloading-large-files-of-unknown-size Thanks

• Cygwin GCC + WinXP cmd.exe does nothing

  - by Stephen Friederichs

  My basic problem is that if I run GCC from the windows command line (cmd.exe in Windows XP) and it does nothing: no .o files are created, no error messages, nothing. It will only throw an error message if I use DOS-style paths, but nothing else. When I run from the Cygwin shell then it will throws error messages as appropriate for the errors in the source and produces the .o files as it needs. Using 'make' from the DOS command line doesn't work either. Has anyone encountered this behavior before?

• Force Response to Download File(s) to Desktop with Ruby?

  - by viatropos

  I was thinking about making a little crop/resize batch processor online, and wanted to know if there was a way for me to do the following: upload image and specify dimensions click "process" and remote app resizes image image downloads automatically locally to wherever it was I uploaded it (say from my desktop), but with a new name (based on the time for example). This would make it so I could host a free image processor that never stored any data other than tempfiles. Is that possible? Something like Rails' send_file method, but I'm using Sinatra and am looking for something in pure ruby. What's the basic concept behind this? What if I wanted to do this for multiple files? Åssuming I can get multiple files uploaded no problem, how can I download all of them automatically?

• Which of FILE* or ifstream has better memory usage?

  - by Viet

  I need to read fixed number of bytes from files, whose sizes are around 50MB. To be more precise, read a frame from YUV 4:2:0 CIF/QCIF files (~25KB to ~100KB per frame). Not very huge number but I don't want whole file to be in the memory. I'm using C++, in such a case, which of FILE* or ifstream has better (less/minimal) memory usage? Please kindly advise. Thanks! EDIT: I read fixed number of bytes: 25KB or 100KB (depending on QCIF/CIF format). The reading is in binary mode and forward-only. No seeking needed. No writing needed, only reading. EDIT: If identifying better of them is hard, which one does not require loading the whole file into memory?

• Handling of data truncation (short reads/writes) in FUSE

  - by Vi

  I expect any good program should do all their reads and writes in a loop until all data written/read without relying that write will write everything (even with regular files). Am I right? Implemented simple FUSE filesystem which only allows reading and writing with small buffers, very often returning that it is written less bytes that in a buffer (using -o direct_io). Some programs work, some not (notably mountlo). Are them buggy or programs should not expect truncated writes and reads from the regular files? In general, are seekable file descriptors expected to truncate data like sockets and pipes?

• Trouble creating a makefile

  - by catia

  Hi everyone! I'm having some trouble making a Makefile. Write now I just compile everything every time. Although, the professor is ok with that, I do want to get it working faster and to avoid unnecessary compiling. Here's what I have. FILES= p6.cpp SetIter.cpp Node.cpp Set.cpp CFLAGS= -ansi -pendantic -Wall -Wextra CC= g++ MakePg6: p6.cpp SetIter.cpp Node.cpp Set.cpp $(CC) $(CFLAGS) $(FILES) -o pg6 Node.cpp - node class Set.cpp - uses nodes. Friend of Node. SetIter.cpp - gets a set and uses a pointer to iterator through I'm confused with some of the depencies arising from the friends thing and the point of lib.o being included in the Makefile as some sites have. Any help is greatly appreciated. Thanks in advance.

• Saving full page content using Selenium

  - by Rick

  Hi all, I was wondering what's the best way to save all the files that are retrieved when Selenium visits a site. In other words, when Selenium visits http://www.google.com I want to save the HTML, JavaScript (including scripts referenced in src tags), images, and potentially content contained in iframes. How can this be done? I know getHTMLSource() will return the HTML content in the body of the main frame, but how can this be extended to download the complete set of files necessary to render that page again. Thanks in advance!

• .NET 3.5 SP1 Code from Network - "The system cannot find the file specified."

  - by DaMoose

  This issue has nothing to do with whether the assemblies have been signed or caspol has been run for the shared network folder. Apparently, the location of the files is the issue, but I cannot find what the real problem is. I have one executable that references 5 dll's. I can run the app from a local drive without any problem. When I run the app from a network share, I get an error stating that "Could not load file or assembly 'homer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." If all the files are in the same folder, what is the error really telling me? I should note also that the framework used is 3.5 SP1, which does not require changing code access policy. I had tried that anyhow, and I received the same error in both cases. Thanks, DaMoose

• How to setup Apache 2.2 (prefork) with mod_fcgid to test a C++ application?

  - by skyeagle

  I have written my first fastcgi application (C/C++), and I need to test it to ensure that it is behaving the way I expect it to. I have searched for examples on setting up Apache 2.2. with mod_fcgid, but all of teh tutorials etc I have seen, relate to PHP, Python, Perl etc. Is anyone aware of a resource that shows how I may setup Apache to use mod_fcgid (NOT mod_fastcgi) to test my binary? If no online resource is available (I'd be surprised), then could someone please point out the steps required to do the testing?

• Winform .Net 3.5 - Get path of ApplicationFolder for Office Add-In

  - by Serexx

  Greetings - I am writing an add-in for Expression Web 3 in VS2008 The solution has a Windows Installer setup project in which the ApplicationFolder is tagged to hold some ancillary files. I need to be able to access those files during the add-in's startup, but naturally the Application object as well as the AppDomain reference paths to Expression Web not to the Add-In. There is a tickle in the back of my head that the solution involves reflection but thats as far as I can get... has anyone dealt with this or have any suggestions? Thanks!

• Can NTFS-Search(An OSS project) scan any file on NTFS volume?

  - by Benjamin

  I want to apply NTFS-Search to our project. Our project have to find the files which we specified.(fast and exactly!) But I'm not sure the program(NTFS-Search) works well. What if the file specified is system file? What if the file is being opened by a process with NO_READ_SHARE_MODE? Do you think NTFS-Search can find any files? I don't know about NTFS filesystem well. So I can't find the answer myself. Is there anyone who knows that? I tried to find their email address, but I couldn't find. Thanks in advance.

• Customized generation/filtering resources with maven

  - by zamza

  I wonder what is the Maven way in my situation. My application has a bunch of configuration files, let's call them profiles. Each profile configuration file is a *.properties file, that contains keys/values and some comments on these keys/values semantics. The idea is to generate these *.properties to have unified comments in all of them. My plan is to create a template.properties file that contains something like #Comments for key1/value1 key1=${key1.value} #Comments for key2/value2 key2=${key2.value} and a bunch of files like #profile_data_1.properties key1.value=profile_1_key_1_value key2.value=profile_1_key_2_value #profile_data_2.properties key1.value=profile_2_key_1_value key2.value=profile_2_key_2_value Then bind to generate-resources phase to create a copy of template.properties per profile_data_*, and filter that copy with profile_data_*.properties as a filter. The easiest way is probably to create an ant build file and use antrun plugin. But that is not a Maven way, is it? Other option is to create a Maven plugin for that tiny task. Somehow, I don't like that idea (plugin deployment is not what I want very much).

• c#.net id duplicate reported untruthfully

  - by tracer tong

  I am getting an error in visual studio that appears to be flat out wrong. Here it is: The tag contains duplicate 'ID' attributes. on the following line: Rica.Yoodul.MiniSites.BaseMiniSiteUserControl ucMaster = (Rica.Yoodul.MiniSites.BaseMiniSiteUserControl)Page.LoadControl("~/MiniSites/" + templateName + "/Master.ascx"); I have checked though both the master and child pages for repeats of the id I last added (the only one added since last successful test) and the ID is used once across both files. Other than controls (e.g ), is there anything this error refers to? Or is there a workaround? I have checked I am editing the right files. On the face of it this appears to be a visual studio bug, but I want to be sure.

• Is vbscripting that difficult?

  - by eric young

  I need to write some vbscripts in my new project. I was told by other people that vbscripting is easy, but seems to me, it is not. For example, in the following example (provided by microsoft), these functions: CreateObject, CreateShortcut, as well as these property names: TargetPath, WindowStyle, Hotkey, etc, are used, but I just cannot find the corresponding API documentation about how to use them. In other words, how do you know you need to call these functions in your vbscripts? Visual Studio 2008/2010 do not have templates for vbscript either. Could anybody tell me what I am missing, and what the best way is to do vbscripting? set WshShell = WScript.CreateObject("WScript.Shell") strDesktop = WshShell.SpecialFolders("Desktop") set oShellLink = WshShell.CreateShortcut(strDesktop _ & "\MyExcel.lnk") oShellLink.TargetPath = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE" oShellLink.WindowStyle = 1 oShellLink.Hotkey = "CTRL+SHIFT+F" oShellLink.IconLocation = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE, 0" oShellLink.Description = "My Excel Shortcut" oShellLink.WorkingDirectory = strDesktop oShellLink.Save

• How do I get a list of all languages that my Windows Forms application has been localized to?

  - by Andrei B

  I have localized localized a Form into two language by setting the Localizable property to True and setting the Language from (Default) to (Dutch(Netherlands)), and I changed the control texts. Visual Studio generated the resource files and compiles them into the application. I need to get a simple list of all the languages that my form has been localized into. Currently it would be just two English and Dutch, but more may come. I need to programatically get a list of "what languages my application is localized into". Do I look into the resource files or use ResourceManager or what? Thanks!

• How does Rails Plugin Storage work?

  - by Kevin

  Trying to figure out how to install rails plugins manually on windows so I have a few questions. What does the directory need to be named in vendor/plugins? Is it arbitrary or is it linked to something within the plugin config files or is that what you set in the environment.rb? Once I've copied the files to the correct directory, do I always need to run something inside like init.rb or is it good to go? What's the difference between 'require' and 'include'? Thanks!

• Removing a Subversion folder from the client and server

  - by Code Sherpa

  Hi. I have been using Subversion for a few days now and have a question... I have a folder deep in my subversion trunk that I want to remove and replace with another folder. I have read about this on here and tried: Export: I clicked on the folder I wanted to remove I then created a new backup folder elsewhere when prompted I then exported Delete: I next chose the delete option (in TortoiseSVN) on the folder I wanted to remove and clicked it. The folder I want to remove now has an "X" over it as does all of the subfolders and files. But, when I go to the Subversion repository on the remote server, I still see the folder I want to remove and all of its files. What do I have to do to get the clients to forget about this folder and the Subversion server to remove it permanently from its sub-folders? Thanks in advance...

• Check if NFS share is mounted in python script

  - by Fabian

  I wrote a python script that depends on a certain NFS share to be available. If the NFS share is not mounted it will happily copy the files to the local path where it should be mounted, but fail later when it tries to copy some files back that were created on the NFS server. I'd like to catch this error specifically so I can print a useful error message that will tell the users of this script what they have to do. My first idea would be to execute mount using subprocess and then check the output for this nfs share. But I'm wondering if there isn't a nicer and more robust method of doing it.
