How can i do subtraction of integers in C without using either the unary or binary '-' operator?
Or can we do the same for other data types like float/double?
I am writing a web service that will receive uploads from mobile clients. The data will have 4 or more text fields followed by a large binary field. What is the best standard technology to use for this, as I may make the API public in the future and want to use something that everyone likes. XML? SOAP? Just HTTP and a completely customized payload?
Thanks.
I don't know whether SVN has this feature, How do I tell svn to not maintain the history of changes for a file but it should have only the latest version of the file. Of course this is not the work of a version control, but it will be useful if I want to have some binary files within the repo without versioning.
And, does it cache it locally?
I ask because I am wondering if it's possible to change the sound of a push notification via SSH, replacing an app sound.
My question is specifically about how the API for push notifications works. Does it send a .caf (aiff) binary file for the phone to play each time?
This is a three part question.
One: Would using a
Dictionary<String,Object>
be a good way of saving data where it would be
Dictionary<Key,Value>
as the basis?
Two: What would be a better way without using app.settings or xml?
Three: How would you serialize this(Or the better solution) into a binary format that is compact and serializes quickly?
I commited a lot of files locally (including binary files removing & adding...) and now when I try to push it takes a lot of time. Actually I messed up my local repo history.
How could I avoid this mistake in the future ? Can I transform a set of local revision 1-2-3-4 to 1-2 with 2 being the final revision of the local clone ?
Hi All,
We have a .sqlite file ported with the app, and i wanted to decrypt the file(not just the contents, the whole file), the code we have is able to read a .txt file and i also tried reading the file in binary mode. This isn't working, is there a way to read a .sqlite file from the code.
kindly help
I want to write a python script that populates a database with some information. One of the columns in my table is a BLOB that I would like to save a file to for each entry.
How can I read the file (binary) and insert it into the DB using python? Likewise, how can I retrieve it and write that file back to some arbitrary location on the hard drive?
Does any one know of an example on how to store an image in a SQL Server CE database?
What data type should the column be? (I am guessing binary.)
I use Linq-To-Datasets. Is it possible using that to put the image into the database and pull it out again later?
Thanks for any advice.
I have some data that is base64 encoded that I want to convert back to binary even if there is a padding error in it. If I use
base64.decodestring(b64_string)
it raises an 'Incorrect padding' error. Is there another way?
I want to look at a production binary and know which revision in the SCM corresponds to that build. How it is possible? Can I accomplish that in Visual Studio using VSS?
I noticed that when I build a given C# source to produce a DLL, the binary output is different each time. It would be helpful for our build / deployment process if this was not the case. Can I control this?
Hey.. my question is how to prevent someone upload a virus or some malicious code with the extension you pretend for example i have a pdf file uploader, anyone can upload a binary with pdf camouflage there are lots of programs to do that.
I have tried to generate "Hello World" with openxml sdk. To my surprise when trying to open the xml document it was not purely text format but it contains some ugly binary stuff.
Is there any option to have text format when the content is only text ?
I'm currently profiling an implementation of binarysearch. Using some special instructions to measure this I noticed that the code has about a 20% misprediction rate. I'm curious if there is any way to check how many cycles I'm potentially losing due to this. It's a MIPS based architecture.
I am looking for tool that can convert .Glade (or xml) file to C source.
I have tried g2c (Glade To C Translator) but i am looking for windows binary.
Any one does know any good tool for window.
Thanks,

Hi!
I have to deserialize a dictionary in PHP that was serialized using cPickle in Python.
In this specific case I probably could just regexp the wanted information, but is there a better way? Any extensions for PHP that would allow me to deserialize more natively the whole dictionary?
Apparently it is serialized in Python like this:
import cPickle as pickle
data = { 'user_id' : 5 }
pickled = pickle.dumps(data)
print pickled
Contents of such serialization cannot be pasted easily to here, because it contains binary data.
PHP's str_replace() was intended only for ANSI strings and as such can mangle UTF-8 strings. However, given that it's binary-safe would it have a problem if it was only given valid UTF-8 strings as arguments?
Edit: I'm not looking for a replacement function, I would just like to know if this hypothesis is correct.
How can i convert a hex string lenght 6 bytes for example string ='1122aaccddff';
to raw binary data of lenght 8 byes the last 2 bytes shoul be padded with zeros,
The status says "rejected" in iTunes Connect. I replied to the email I got, left the "line" in there that they apparently use for tracking. Do I just wait to hear back from them or do I reject the entire binary and start over? It's not clear from the email or the site what is supposed to or will happen next.
Hello!
How do I know that I can safely upgrade Boost Serialization Library on a production system without breaking compatibility with the existing data ? Is there any test that I should perform in order to be sure that all data stored in the binary format by previous version of the library will be successfully read by the new one ? Does Boost Serialization library itself guarantee some sort of compatibility between versions ?
I'v created a Notepad-like application and if I load a 1MB file into the textbox, it takes about 1 minute. The Visual Studio Binary editor displays lines, Hex, and ascii versions in a fraction of a second. How do they get the data into the textbox so quickly?
Thanks
Is there any way to convert differential backup to SQL statements which will produce identical results when applied?
Or any other solution similar to binary log in MySQL?
