• Silverlight binaries what are .ni.dlls?

  - by BrettRobi

  In browsing around the Silverlight installation directory I see a number of framework DLLs as expected. But I also see a separate DLL with the same name but with .ni inserted between the dll name and extension. For example there is a System.dll and System.ni.dll. There appears to be a sister .ni dll for almost all of the system dlls. Looking at the quickly in Reflector they appear to include the same content, but are much bigger in binary size. Just out of curiosity, can anyone explain what these are?

• Converting Flash frame to JPEG

  - by dhorn

  We are attempting to convert a flash frame into a JPEG without using the Flex SDK or other adobe tools. Right now, we have a flash file that passes binary data over to a .cfm page, which uses the following code to change the headers: <cfset var = GetHttpRequestData()> <cfcontent type="image/jpeg"> <cfheader name="Content-Disposition" value="attachment; filename=#url.name#"> <cfoutput>#var.content#</cfoutput> This code is producing some strange results. Basically, it renders as an image, and I can "right click - Set as desktop background", but I cannot save the image any other way, as it simply saves the contents of the HTML Source. So, questions: 1) Is what I'm trying to do even possible? 2) If so, any suggestions? Thanks guys.

• Untrusted GPGPU code (OpenCL etc) - is it safe? What risks?

  - by Grzegorz Wierzowiecki

  There are many approaches when it goes about running untrusted code on typical CPU : sandboxes, fake-roots, virtualization... What about untrusted code for GPGPU (OpenCL,cuda or already compiled one) ? Assuming that memory on graphics card is cleared before running such third-party untrusted code, are there any security risks? What kind of risks? Any way to prevent them ? (Possible sandboxing on gpgpu or other technique?) P.S. I am more interested in gpu binary code level security rather than hight-level gpgpu programming language security (But those solutions are welcome as well). What I mean is that references to gpu opcodes (a.k.a machine code) are welcome.

• fread() behaves weird

  - by Cres

  hi, I have a problem in a C program of mine where after I use fread(), the file pointer goes to the end of the file sometimes. I'll try to explain better - the code looks something like: dummy = ftell(fp); fread(&buf, sizeof(unsigned char), 8, fp); dummy = ftell(fp); where fp is a file pointer to an opened file (opened it with "w+", I'm using it as a binary file and I know i'm supposed to have a "b" in there too, but I heard its not really important to add it..), dummy is just an unsigned long variable, and buf is unsigned char[8] now, when debugging, at the ftell before the fread, dummy is 262062 at the ftell after the fread, dummy is 262640 even though I only 'moved' 8 bytes.. does anyone have any idea what can be the cause of this..? thanks for your help :)

• Python+Windows+GStreamer = Impossible (for me)?

  - by james

  Hi :) essentially, my problem is, ater a long time searching, finding only this other question, i decided i was just going to ask my own... i am on windows 7 with python 2.6 and ossbuild GStreamer, but i am trying to get the python binding for it, and struggling. i have got gst-python from http://gstreamer.freedesktop.org/src/gst-python/ but as my eyes and research tell me, it does not work in the setup.py way, and the other question has a link to a site that he says has a binary avaiable, which no longer does, http://www.gstreamer-winbuild.ylatuya.es/doku.php?id=download and even the sdk is gone, and ossbuild dont seem to have anything useful either. so essentially, my question is, can anyone tell me a method, however convoluted, of getting my setup so if i write a script for (py)gst, with an import gst it will work? not the best of explanations... im tired k? xxx :)

• best way to output a full precision double into a text file

  - by flevine100

  Hi, I need to use an existing text file to store some very precise values. When read back in, the numbers essentially need to be exactly equivalent to the ones that were originally written. Now, a normal person would use a binary file... for a number of reasons, that's not possible in this case. So... do any of you have a good way of encoding a double as a string of characters (aside from increasing the precision). My first thought was to cast the double to a char[] and write out the chars. I don't think that's going to work because some of the characters are not visible, produce sounds, and even terminate strings ('\0'... I'm talkin to you!) Thoughts?

• ruby on rails: audio/mp3 content header download

  - by bandhunt

  How do you set the headers for downloads in ruby/rails? In php I'd set the header for an mp3 download like this: header("Content-Transfer-Encoding: binary"); header("Content-type: audio/mp3"); header("Content-Disposition: attachment; filename=\"$songname.mp3\""); header("Content-Length: " . $size); @readfile("http://example.com/12345.mp3"); Seems like there should be an easy should an easy solution. I did find this: response.headers['Content-type'] = 'Content-type: audio/mp3' But I'm not sure how/where the readfile would come into play and other headers. Thanks!

• DatabaseName.bak File Transfer Problem

  - by Jordon

  I have downloaded databasename.bak file from my hosting company, when i tried to restore that DB file in SQL server 2008 it is keep on giving me following error. The media family on device 'C:\go4sharepoint_1384_8481.bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE HEADERONLY is terminating abnormally. (Microsoft SQL Server, Error: 3241) According to this error and from following link http://www.sqlcoffee.com/Troubleshooting047.htm Later when I tried to restore file on server it was restored correctly, but when I tried to transfer same file using FTP Software FileZila and tried to restore that downloaded file it was giving above error. That is file is getting corrupted on the way to tranfer using FTP. Any Idea how can i avoid that file to get courrupt? Note: File is downloaded using FileZila - TransferType as Binary. Thank you.

• How do I use BCP or Sql Server Management Studio to get BLOB data our of Sql Server?

  - by Eric

  I'm sorry if this question has been asked already, but I couldn't find it anywhere. I have a table that stores files as BLOBS. The column that holds the file is an image datatype. I would like to be able to extract the binary data out of the column and turn it in to an actual file. I would ideally like to be able to do this with BCP or management studio if possible. I have tried BCP, but for some reason when I try and pull out an office document Word thinks it's corrupt. Here's what I've tried so far (obviously the values have been changed to protect the innocent :): bcp "select document_binary_data from database where id = 12345" queryout "c:\filename.doc" -n -S server -U username -P password This isn't working though? Any thoughts?

• Reintegrate a branch with externals fails in SVN

  - by dnndeveloper

  What I am doing: Apply external properties to a folder in the trunk (both single file and folder external, externals are binary files) Create a branch from the trunk and update the entire project Modify a file on the branch and commit the changes, then update the entire project. Merge - "Reintegrate a branch" when I get to the last screen I click "test merge" and get this error: Error: Cannot reintegrate into mixed-revision working copy; try updating first I update the entire project and still the same error. Other observations: If I "Merge a range of revisions" everything works fine. If I remove the externals everything works fine using either "Merge a range of revisions" or "Reintegrate a branch". How do I solve this issue? I am using Subversion 1.6.6 with TortoiseSVN 1.6.6.

• Sintra app in a gem

  - by JP

  I have a Sinatra application I've created and I'd like to package it as a gem-based binary. I have my gemspec and gem set up to generate a suitable executable that points to the my_sinatra_app.rb (which is executable) but the sinatra server never runs. Any ideas why and how to make it work? my_sinatra_app executable: #!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby # # This file was generated by RubyGems. require 'rubygems' version = ">= 0" if ARGV.first =~ /^_(.*)_$/ and Gem::Version.correct? $1 then version = $1 ARGV.shift end gem 'my_sinatra_app', version load Gem.bin_path('my_sinatra_app', 'my_sinatra_app', version)

• Is it a good idea to use .Net for commercial software?

  - by user146780

  I was playing around with .Net reflector today and realized that Miicrosoft's entire Expression suite is written in .Net. As a result I was pretty much able to see the underlying code for expression. This makes it far easier than binary to break copy protection. I think that that's a big deal. Is it generally recommended to make commercial software in .Net where it is fairly easy to see the source code down to the variable names? I was surprised that Microsoft didn't at least dotfescate it. Thanks

• Base64 Encoded Data - DB or Filesystem

  - by Marty

  I have a new program that will be generating a lot of Base64 encoded audio and image data. This data will be served via HTTP in the form of XML and the Base64 data will be inline. These files will most likely break 20MB and higher. Would it be more efficient to serve these files directly from the filesystem or would it be feasible to store the data in a MySQL database? Caching will be set up but overall unnecessary because it is likely that this data will be purged shortly after it is created and served. i know that storing binary data in the DB is frowned upon in most circumstances but since this will all be character data I want to see what the consensus is. As of now, I am leaning toward storing them in the filesystem for efficiency reasons but if it is feasible to store them in a database it would be much easier to manage the data.

• SQL Server many-to-many design recommendation

  - by Jean-Philippe Brabant

  I have a SQL Server database with two table : Users and Achievements. My users can have multiple achievements so it a many-to-many relation. At school we learned to create an associative table for that sort of relation. That mean creating a table with a UserID and an AchivementID. But if I have 500 users and 50 achievements that could lead to 25 000 row. As an alternative, I could add a binary field to my Users table. For example, if that field contained 10010 that would mean that this user unlocked the first and the fourth achievements. Is their other way ? And which one should I use.

• What information about me and my system do compilers add to executeables?

  - by I can't tell you my name.

  I'm currently using Microsoft Visual Studio 2010. If we say that we give 10 different people a copy of MSVC 10 and a short C++ Hello, World listing. They all create a new project using exactly the same settings, add a new cpp file with the Hello, World program and compile it. Do they all get the exactly same binary? If not, what are the exact differences? What information about my system does MSVC add to my executeable? Paranoia!

• Whats the best data-structure for storing 2-tuple (a, b) which support adding, deleting tuples and c

  - by bhups

  Hi So here is my problem. I want to store 2-tuple (key, val) and want to perform following operations: - keys are strings and values are Integers - multiple keys can have same value - adding new tuples - updating any key with new value (any new value or updated value is greater than the previous one, like timestamps) - fetching all the keys with values less than or greater than given value - deleting tuples. Hash seems to be the obvious choice for updating the key's value but then lookups via values will be going to take longer (O(n)). The other option is balanced binary search tree with key and value switched. So now lookups via values will be fast (O(lg(n))) but updating a key will take (O(n)). So is there any data-structure which can be used to address these issues? Thanks.

• Automatic upload of 10KB file to web service?

  - by Joseph Turian

  I am writing an application, similar to Seti@Home, that allows users to run processing on their home machine, and then upload the result to the central server. However, the final result is maybe a 10K binary file. (Processing to achieve this output is several hours.) What is the simplest reliable automatic method to upload this file to the central server? What do I need to do server-side to prevent blocking? Perhaps having the client send mail is simple and reliable? NB the client program is currently written in Python, if that matters.

• Test for undefined references in Linux

  - by Charles

  Is there a built in linux utility that I can use to test a newly compiled shared library for external undefined references? Gcc seems to be intelligent enough to check for undefined symbols in my own binary, but if the symbol is a reference to another library gcc does not check at link time. Instead I only get the message when I try to link to my new library from another program. It seems a little silly to get undefined reference messages in a library when I am compiling a different project so I want to know if I can do a check on all references internal and external when I build the library not when I link to it. Example error: make -C UnitTests debug make[1]: Entering directory `~/projects/Foo/UnitTests` g++ [ tons of objects ] -L../libbar/bin -lbar -o UnitTests libbar.so: undefined reference to `DoSomethingFromAnotherLibrary` collect2: ld returned 1 exit status make[1]: *** [~/projects/Foo/UnitTests] Error 1

• Storing rich text documents

  - by David Veeneman

  This is a follow-up to another question I asked earlier today. I am creating a desktop app that stores rich text documents created in WPF (in a RichTextBox control). The app uses SQL Compact, and up until now, I had planned to store each document in a binary column in the database. I am rethinking that approach. Would it be better practice to store each rich text document in the file system, rather than saving it to the database? I figure I could put the documents in the same folder with the database, then store a relative path to each document in its database record, along with other information about the document (tags and so on). I'd like to know some pros and cons of that approach, along with ideas of what is generally considered best practice for this sort of thing. Thanks for your help.

• Operations on bytes in C#

  - by Hooch

  Hello. I'm writing application to control LEDS on LPT. I have everything working except this. This is one small function. I have sth like that: I want to build function that will take two argument and return one number: In actual code those binary numers will be in hex. I put them there like that so that it's easier for you to visualize it. Example1: arg1 = 1100 1100 arg2 = 1001 0001 retu = 0100 1100 Example2: arg1 = 1111 1111 arg2 = 0001 0010 retu = 1110 1101 Example3: arg1 = 1111 0000 arg2 = 0010 0010 retu = 1101 0000 I have no idea how this function should look like. I want it to be as fast as possible. I'll call this function 200 times per second.

• fork within Cocoa application

  - by liuliu

  My problem is not the best scenario for fork(). However, this is the best func I can get. I am working on a Firefox plugin on Mac OSX. To make it robust, I need to create a new process to run my plugin. The problem is, when I forked a new process, much like this: if (fork() == 0) exit(other_main()); However, since the state is not cleaned, I cannot properly initialized my new process (call NSApplicationLoad etc.). Any ideas? BTW, I certainly don't want create a new binary and exec it.

• Embedded C++, any tips to avoid a local thats only used to return a value on the stack?

  - by lisarc

  I have a local that's only used for the purposes of checking the result from another function and passing it on if it meets certain criteria. Most of the time, that criteria will never be met. Is there any way I can avoid this "extra" local? I only have about 1MB of storage for my binary, and I have several thousand function calls that follow this pattern. I know it's a minor thing, but if there's a better pattern I'd love to know! SomeDataType myclass::myFunction() { SomeDataType result; // do I really need this local??? // i need to check the result and pass it on if it meets a certain condition result = doSomething(); if ( ! result ) { return result; } // do other things here ... // normal result of processing return SomeDataType(whatever); }
