  • How to use UIWebView to get scrolling text ?

    - by srikanth rongali
    Hi, In my iPhone application I need a scrolling text. I had the text to be displayed and scrolled up and down but I could not get customized text. I mean all the text is of same font. I need some different font size text . I am using UITextView, but UITextView do not support customized text in it. How can I have the scrolling text which has different font size. I read that to use UIWebView for this. But, I could not understand how to use it. the text contains no url's no editing.(It need to be just static text to read). How can I do this ? Thank you.

  • Rails streaming file download

    - by Leonard Teo
    I'm trying to implement a file download with Rails. I want to eventually migrate this code to using S3 to serve the file. I've copied the Rails send_file code almost verbatim and I cannot seem to get it to stream a file to the user. What happens is that it sends 'a' file to the user, but the downloaded file itself simply contains the text.inspect of the Proc: # What am I doing wrong here? options = {} options[:length] = File.size(file.path) options[:filename] = File.basename(file.path) send_file_headers! options render :status => 200, :text => Proc.new { |response, output| len = 4096 File.open(file.path, 'rb') do |fh| while buf = fh.read(len) output.write(buf) end end } Ps: I've read in a number of other posts that it's not advisable to send files through the Rails stack, and if possible serve using the web server, or in the case of S3 use the hashed URL it can provide. Yes, we really do want to serve the file through the Rails stack.

  • Is there a secure p2p distributed database?

    - by p2pgirl
    I'm looking for a distributed hash table to store and retrieve values securely. These are my requirements: It must use an existing popular p2p network (I must guarantee my key/value will be stored and kept in multiple peers). None but myself should be able to edit or delete the key/value. Ideally an encryption key that only I have access to would be required to edit my key value. All peers would be able to read the key value (read-only access, only the key holder would be able to edit the value) Is there such p2p distributed hash table? Would the bittorrent distributed hash table meet my requirements?' Where could I find documentation?

  • Why do Lua arrays(tables) start at 1 instead of 0?

    - by AraK
    Hi, I don't understand the rational behind the decision of this part of Lua. Why does indexing start at 1? I have read(as many others did) this great paper. It seems to me a strange corner of a language that is very pleasant to learn and program. Don't get me wrong, Lua is just great but there has to be an explanation somewhere. Most of what I found(on the web) is just saying the index starts at 1. Full stop. It would be very interesting to read what its designers said about the subject. Note that I am "very" beginner in Lua, I hope I am not missing something obvious about tables.

  • How to know from a bash script if the user abruptly closes ssh session

    - by Figo
    I have a bash script that acts as the default shell for a user loging in trough ssh. It provides a menu with several options one of wich is sending a file using netcat. The netcat of the embedded linux I'm using lacks the -w option, so if the user closes the ssh connection without ever sending the file, the netcat command waits forever. I need to know if the user abruptly closes the connection so the script can kill the netcat command and exit gracefully. Things I've tried so far: Trapping the SIGHUP: it is not issued. The only signal issued i could find is SIGCONT, but I don't think it's reliable and portable. Playing with the -t option of the read command to detect a closed stdin: this would work if not for a silly bug in the embedded read command (only times out on the first invocation)

  • How to automate testing of a browser-based app?

    - by mawg
    If it were a windows program, I would use Auto it to automate testing. Is there something similar for browser-based apps? Nothing too complex, it should just allow scripting (preferable for me to macro-recording) to simulate human interaction with the browser, which means being able to identify fields of a form by name, inject text into some, simulate mouse-click on others, etc and then, after submitting a form, should be able to read text certain named controls, check the status of others (checked, radio group index, read-only, etc). While I do appreciate a full featured product, I don't appreciate a steep learning curve. so something as simple as the scripting of Auto It woudl be fine. I don't know if it makes a difference which browser is used, but I could live with MSIE 6 or higher (maybe 7 or higher at a push).

  • CSS selectors : should I minimise my use of the class attribute in the HTML or optimise the speed

    - by Laurent Bourgault-Roy
    As I was working on a small website, I decided to use the PageSpeed extension to check if their was some improvement I could do to make the site load faster. However I was quite surprise when it told me that my use of CSS selector was "inefficient". I was always told that you should keep the usage of the class attribute in the HTML to a minimum, but if I understand correctly what PageSpeed tell me, it's much more efficient for the browser to match directly against a class name. It make sense to me, but it also mean that I need to put more CSS classes in my HTML. It also make my .css file a little harder to read. I usually tend to mark my CSS like this : #mainContent p.productDescription em.priceTag { ... } Which make it easy to read : I know this will affect the main content and that it affect something in a paragraph tag (so I wont start to put all sort of layout code in it) that describe a product and its something that need emphasis. However it seem I should rewrite it as .priceTag { ... } Which remove all context information about the style. And if I want to use differently formatted price tag (for example, one in a list on the sidebar and one in a paragraph), I need to use something like that .paragraphPriceTag { ... } .listPriceTag { ... } Which really annoy me since I seem to duplicate the semantic of the HTML in my classes. And that mean I can't put common style in an unqualified .priceTag { ... } and thus I need to replicate the style in both CSS rule, making it harder to make change. (Altough for that I could use multiple class selector, but IE6 dont support them) I believe making code harder to read for the sake of speed has never been really considered a very good practice . Except where it is critical, of course. This is why people use PHP/Ruby/C# etc. instead of C/assembly to code their site. It's easier to write and debug. So I was wondering if I should stick with few CSS classes and complex selector or if I should go the optimisation route and remove my fancy CSS selectors for the sake of speed? Does PageSpeed make over the top recommandation? On most modern computer, will it even make a difference?

  • How does the verbosity of identifiers affect the performance of a programmer?

    - by DR
    I always wondered: Are there any hard facts which would indicate that either shorter or longer identifiers are better? Example: clrscr() opposed to ClearScreen() Short identifiers should be faster to read because there are fewer characters but longer identifiers often better resemble natural language and therefore also should be faster to read. Are there other aspects which suggest either a short or a verbose style? EDIT: Just to clarify: I didn't ask: "What would you do in this case?". I asked for reasons to prefer one over the other, i.e. this is not a poll question. Please, if you can, add some reason on why one would prefer one style over the other.

  • Using memory mapping in C for reading binary

    - by user1320912
    I am trying to read data from a binary file and process it.It is a very large file so I thought I would use memory mapping. I am trying to use memory mapping so I can read the file byte by byte. I am getting a few compiler errors while doing this. I am doing this on a linux platform #include <unistd.h> #include <sys/types.h> #include <sys/mman.h> int fd; char *data; fd = open("data.bin", O_RDONLY); pagesize = 4000; data = mmap((caddr_t)0, pagesize, PROT_READ, MAP_SHARED, fd, pagesize); The errors i get are : caddr not initialized, R_RDONLY not initialized, mmap has too few arguments. Could someone help me out ?

  • In .NET which loop runs faster for or foreach

    - by Binoj Antony
    In c#/VB.NET/.NET which loop runs faster for or foreach? Ever since I read that for loop works faster than foreach a long time ago I assumed it stood true for all collections, generic collection all arrays etc. I scoured google and found few articles but most of them are inconclusive (read comments on the articles) and open ended. What would be ideal is to have each scenarios listed and the best solution for the same e.g: (just example of how it should be) for iterating an array of 1000+ strings - for is better than foreach for iterating over IList (non generic) strings - foreach is better than for Few references found on the web for the same: Original grand old article by Emmanuel Schanzer CodeProject FOREACH Vs. FOR Blog - To foreach or not to foreach that is the question asp.net forum - NET 1.1 C# for vs foreach [Edit] Apart from the readability aspect of it I am really interested in facts and figures, there are applications where the last mile of performance optimization squeezed do matter.

  • Can StructureMap be configured so that one can use different .config settings based on whether the p

    - by Mark Rogers
    I know that in StructureMap I can read from my *.config files (or files referenced by them), when I want to pass specific arguments to an object's constructor. ForRequestedType<IConfiguration>() .TheDefault.Is.OfConcreteType<SqlServerConfiguration>() .WithCtorArg("db_server_address") .EqualToAppSetting("data.db_server_address") But what I would like to do is read from one config setting in debug mode and another in release mode. Sure I could surround the .EqualToAppSetting("data.db_server_address"), with #if DEBUG, but for some reason those statements make me cringe a little when I put them in. I'd like to know if there was some way to do this with the StructureMap library itself. So can I feed my objects different settings based on whether the project is built in debug or release mode?

  • Import a number of csv files and replace NA by Zeros

    - by tao.hong
    I know how to do this individually. However, I have more than 1000 files. I decided to use a for loop. However, it seems like I did not find the correct way to evaluate my variables. Here is my code setwd('C:/data') filenames=dir() #find file names for (i in filenames){ adt = substr(x = i, start = 1, stop = nchar(i)-4) name=paste("data_", adt, sep="") assign(name, read.csv(i,header=T,sep=",")) #read each file and assign a variable name starting with data_ to it func=paste('name[is.na(name)] <- 0',sep="") # here is the place I have problem. R will not consider name is a parameter whose values change in each iteration eval((text=func)) }

  • download mail attachment with Java

    - by Don
    Hi, I had a look in the reference doc, and Spring seems to have pretty good support for sending mail. However, I need to login to a mail account, read the messages, and download any attachments. Is downloading mail attachments supported by the Spring mail API? I know you can do this with the Java Mail API, but in the past I've found that very verbose and unpleasant to work with. EDIT: I've received several replies pointing towards tutorials that describe how to send mail with attachments, but what I'm asking about is how to read attachments from received mail. Cheers, Don

  • Flex DataGrid reads a field from lastResult.node as number

    - by Nemi
    Why Flex 3 DataGrid reads a string from XML lastResult.node as number? A field is saved as var_char in mysql, php reads it as string and pass it OK. If there are more then 16 charaters it gets rounded.... For example: this in database cell: 12345678901234567 gets read in DataGrid as nubmer as 12345678901234568 this is in database cell: 5555544444222223333377777 php reads it same and puts it in XML flex reads XML into arrayCollection and DataGrid reads it as: 5.55554444422222e+24 So it reads it as number, why? And how to make it read as String? I tried with labelFunction, no help.

  • Custom component creation - how to add small icon representing component in Tool Palette?

    - by Wodzu
    Please bear in mind that I've read all the instructions I could find about adding component icon to my custom component. And I am able to do this when we talk about the icon size which is 24x24 pixels. I see the icon when a component is dropped on the form. However I can not see the small 16x16 icon which should be displayed when browsing Tool Palette. I've read that I should name my two other BMP files which are contained in DCR file like this: MyComponentName16 [for 16x16 BMP file] MyComponentName32 [for 32x32 BMP file] Unfortunately this does not seem to work, I've tried to restart Delphi few times in hope that it might be the case of not refreshing something, but without any success. Any ideas?

  • Find strong name signature without calling LoadAssembly

    - by Todd Kobus
    When reading a Windows PE file directly, I can't seem to find the strong name of a delay signed assembly. I can get to the CLR Header and read all the CLR header entries including the flags and the StrongNameSignature field. Unfortunately in a delay signed assembly the StrongNameSignature is zeroed out. Is the information in the MetaData directory specified within the CLR header? If so does anyone have an example of how to read this table? I am not interested in calling SN.exe or loading the assembly.

  • HTTP request stream not readable outside of request handler

    - by Jason Young
    I'm writing a fairly complicated multi-node proxy, and at one point I need to handle an HTTP request, but read from that request outside of the "http.Server" callback (I need to read from the request data and line it up with a different response at a different time). The problem is, the stream is no longer readable. Below is some simple code to reproduce the issue. Is this normal, or a bug? function startServer() { http.Server(function (req, res) { req.pause(); checkRequestReadable(req); setTimeout(function() { checkRequestReadable(req); }, 1000); setTimeout(function() { res.end(); }, 1100); }).listen(1337); console.log('Server running on port 1337'); } function checkRequestReadable(req) { //The request is not readable here! console.log('Request writable? ' + req.readable); } startServer();

  • Python - network buffer handling question...

    - by Patrick Moriarty
    Hi, I want to design a game server in python. The game will mostly just be passing small packets filled with ints, strings, and bytes stuffed into one message. As I'm using a different language to write the game, a normal packet would be sent like so: Writebyte(buffer, 5); // Delimit type of message Writestring(buffer, "Hello"); Sendmessage(buffer, socket); As you can see, it writes the bytes to the buffer, and sends the buffer. Is there any way to read something like this in python? I am aware of the struct module, and I've used it to pack things, but I've never used it to actually read something with mixed types stuck into one message. Thanks for the help.

  • Import part with specific meta data using MEF Preview 5

    - by Riri
    I have a export defined as as follows in MEF preview 5 [ExportMetadata("Application", "CheckFolderApplication")] [Export(typeof(ExtendedArtifactBase))] public class CheckFolderArtifact2 : ExtendedArtifactBase { ... Then I only want those imports with the "Application" "CheckFolderApplication" metadata. To currenly do that I read all the imports and then filter the result. [Import(typeof(ExtendedApplicationBase))] private ExportCollection<IApplication> _applications { get; set; } public IApplication GetApplication(string applicationName) { return _applications.Single(a => a.GetExportedObject().Name == applicationName).GetExportedObject(); } This feels really inefficient. What if I have thousands of plug-ins - do I have to read them all via MEF to just get one with the right metadata? If so how do you cache the result?

  • C++0x, How do I expand a tuple into variadic template function arguments?

    - by Gustaf
    Consider the case of a templated function with variadic template arguments: template<typename Tret, typename... T> Tret func(const T&... t); Now, I have a tuple t of values. How do I call func() using the tuple values as arguments? I've read about the bind() function object, with call() function, and also the apply() function in different some now-obsolete documents. The GNU GCC 4.4 implementation seems to have a call() function in the bind() class, but there is very little documentation on the subject. Some people suggest hand-written recursive hacks, but the true value of variadic template arguments is to be able to use them in cases like above. Does anyone have a solution to is, or hint on where to read about it?

  • Reading membership section from web.config in C#

    - by PlayKid
    Hi there, I have created a custom MembershipProvider class, so far so good, however, I am not sure how to read the configuration settings from the web.config file. I tried to search from Google and Stackoverflow, seems like someone also experiencing my problem and asked, but no answer has been given. It should be a simple thing, but I am very new in web development, so reading settings from web.config seems away too technical to me. Here is my settings: <membership defaultProvider="CustomMembershipProvider"> <providers> <clear/> <add name="CustomMembershipProvider" type="Test.Models.CustomMembershipProvider,Test" passwordFormat="Hashed" connectionStringName="ApplicationServices" minRequiredPasswordLength="8" minRequiredNonalphanumericCharacters="0" maxInvalidPasswordAttempts="5" enablePasswordReset="false" enablePasswordRetrieval="false" requiresQuestionAndAnswer="false" applicationName="/"/> </providers> </membership I would like to read the minRequiredPasswordLength setting, please assist. Thanks alot in advance.

  • reading a file that doesn't exist

    - by John
    Hi, I have got a small program that prints the contents of files using the system call - read. unsigned char buffer[8]; size_t offset=0; size_t bytes_read; int i; int fd = open(argv[1], O_RDONLY); do{ bytes_read = read(fd, buffer, sizeof(buffer)); printf("0x%06x : ", offset); for(i=0; i<bytes_read; ++i) { printf("%c ", buffer[i]); } printf("\n"); offset = offset + bytes_read; }while(bytes_read == sizeof(buffer)); Now while running I give a file name that doesn't exist. It prints some kind of data mixed with environment variables and a segmentation fault at the end. How is this possible? What is the program printing? Thanks, John
