  • Xcode & passing command line arguments

    - by Brisco
    I just started working with C & Xcode and I've run into a little difficulty. All I want to do is read a file from the command line and see the output in the terminal. I think my problem lies with the path to the file that I want to read in. I'm using a Mac and the file is on my desktop, so the path should be Users/myName/Desktop/words.txt. Is this correct? This is my code: #import <Foundation/Foundation.h> int main (int argc, const char* argv[]){ if(argc == 1){ NSLog(@" you must pass at least one arguement"); return 1; } NSLog(@"russ"); FILE* wordFile = fopen(argv[1] , "r"); char word[100]; while (fgets(word,100,wordFile)) { NSLog(@" %s is %d chars long", word,strlen(word)); } fclose(wordFile); return 0; }//main

  • Joda-Time: Period to string

    - by tt
    I'm using the Joda-Time library with Java. I'm having some difficulty trying to turn a Period object to a string in the format of "x days, x hours, x minutes". These Period objects are first created by adding an amount of seconds to them (they are serialized to XML as seconds and then recreated from them). If I simply use the getHours() etc. methods in them, all I get is zero and the total amount of seconds with getSeconds. How can I make Joda calculate the seconds into the respective fields, like days, hours, etc...?

  • How can I only allow certain filetypes on upload in php?

    - by Chris
    I'm making a page where the user upload a file. I want an if statement to create an $error variable if the file type is anything other jpg, gif, and pdf. Here's my code: $file_type = $_FILES['foreign_character_upload']['type']; //returns the mimetype if(/*$file_type is anything other than jpg, gif, or pdf*/) { $error_message = 'Only jpg, gif, and pdf files are allowed.'; $error = 'yes'; } I'm having difficulty structuring the if statement. How would I say that?

  • Java service wrapper and additional application command line parameters

    - by Jake
    I'm currently using java service wrapper to wrap a java application that I've developed. I'm needing to ability to pass in additional command line parameters to my application through the java service wrapper. Pretend my app is called myapp and I've setup java service wrapper so that the script I run to start is called myapp. I'd like to be able to do something like this: ./myapp start Parameter1 parameter2 and have those additional parameters get passed into my application. Any ideas how to do this? I'm finding that googling and looking at the documentation is only pulling up how to use command line arguments to setup java service wrapper. I've had difficulty finding anything about passing command line arguments to your application except for having them hard coded in your wrapper.conf file. Right now I feel like my option is to take the additional command line parameters, set them to environment variables and have those hard coded in the wrapper.conf. I'd prefer not to go down that road though and am hoping I've overlooked something.

  • PHP gallery, thumbnail listing

    - by Benjamin
    Hi everyone, I am planning a dynamic PHP photo gallery and having difficulty deciding on the best way to display the thumbnails after they have been retrieved via MySQL. I considered using an inline unordered list but this resulted in the thumbs being stacked one on top of the other (touching). Also tried a table but not sure how I would start the next row after x number of thumbnails. Any suggestions on page layout for this purpose? I will be using Lightbox to cycle through the photos themselves, that isn't the issue. Also, would a while() loop be best for fetching the list of thumbs and inserting the appropriate HTML? Thanks! -Ben

  • Python In-memory table

    - by nsharish
    What is the right way to forming in-memory table in python with direct lookups for rows and columns.I thought of using dict of dicts this way, class Table(dict): def __getitem__(self, key): if key not in self: self[key]={} return dict.__getitem__(self, key) table = Table() table['row1']['column1'] = 'value11' table['row1']['column2'] = 'value12' table['row2']['column1'] = 'value21' table['row2']['column2'] = 'value22' >>>table {'row1':{'column1':'value11','column2':'value12'},'row2':{'column1':'value21','column2':'value22'}} I had difficulty in looking up for values in columns. >>>'row1' in table True >>>'value11' in table['row1'].values() True Now how do I do lookup if 'column1' has 'value11' Is this method of forming tables wrong?Is there a better way to implement such tables with easier lookups?.Thanks

  • Starting Tornado Web

    - by picklepete
    Hi, I'm quite new to using Tornado Web as a web server, and am having a little difficulty keeping it running. I normally use Django and Nginx, and am used to start/stop/restarting the server. However with Tornado I'm having trouble telling it to "run" without directly executing my main python file for the site, ie "python ~/path/to/server.py". I'm sure I'm getting this completely wrong - is there a way of 'bootstrapping' my script so that when Nginx starts, Tornado starts? Any help would be appreciated!

  • Parsing JPEG file format: Format of entropy-coded segment (ECS) segments?

    - by me2
    I'm having difficulty understanding the ITU-T T.81 spec for the JPEG file format. Hopefully someone else here has tried to parse JPEG files and/or knows about the details of this file format. The spec indiates that the ECS0 segment starts after the SOS segment but I can't find where in the spec it actually talks about the format of the ECS0 segment or how do detect its start. Simple JPEG implementations online are of limited help because they assume many things about the JPEGs they parse. Can anyone point me in the right direction?

  • Exclude all normal alphanumeric character from a mixed chinese-and-alphanumeric character word list

    - by Christine
    I have a list of chinese characters and normal alphanumeric characters, mixed together, and I want to get rid of any element that contains an alphanumeric character. Is there a simple way to do this? If I simply exclude any element that contains an alphanumeric character, I get no result because the chinese characters (in utf-8) are similarly affected. I also tried [w for w in fourchar if w.startswith("\x")] to try to get the chinese characters but I'm not sure if that's valid at all. I'm having difficulty figuring out what the alphanumeric characters are in unicode. Thanks for any help!

  • Mixing static and dynamic endpoints in app.yaml file

    - by Greg
    I'm trying to describe endpoints in my App Engine app and am having difficulty for directory structures that mix static and dynamic content. But my yaml rules are conflicting with one another. Before I change my directory structure, does anyone have a recommendation? The goal is to create a directory that contains both documentation (static html files) and implementations. /api - /v1 - getitdone.py - doc.html - index.html What I think I should be doing with my application yaml... - url: /api/v1/getitdone script: api/v1/getitdone.py - url: /api/ static_files: api/index.html upload: api/index.html - url: /api static_dir: api But this causes the dynamic endpoints to fail. I'm assuming the static_dir reference is breaking it. How can I do this without describing every script and static file reference (I have many more than are listed here)?

    I am trying to perform literal match with regular expression using wildcard. string utterance = "Show me customer id 19"; string pattern 1 = "*tom*"; string patter 2 = "*customer id [0-9]*"; Desired results: if (Regex.IsMatch(utterance, pattern 1 )) { MATCH NOT FOUND } if (Regex.IsMatch(utterance, pattern 2 )) { MATCH FOUND } I have tried looking for literal match solution/syntax in wildcard but having difficulty. Could you also enlighten me with with an example on possible Pattern Matching Strength algorithm i.e. if code match 90 select? Note: I have table with 100000 records to perform literal matches from user utterances. Thanks in advance.

  • linux display drivers

    - by salman
    I've run into a major display problem on newly installed fedora 11, on my 6 years old pc which runs a pentium4 2.4 GHz processor, 1 gb ddr ram, intel 845 motherboard with integrated graphics card. When i open an image or play a video, my complete screen turns garbled. I simply cannot make out whats on my screen. With difficulty i have to close the image/video window and move around the folder window to clean the screen image. Is it because of my display drivers? How can i fix it? I also ran into mp3 plugins and flash issues which i was able to resovle. I'm new to linux, the sole purpose of isntalling it on my old pc was to learn linux but this display problem is frustrating me. Thanks, Salman

  • Restlets with Google App Engine, Java Server Pages, (JSP's), and Shiro authentication

    - by DutrowLLC
    I'm having difficulty integrating Restlets into my project. I'm using google app engine (GAE) and I also have some java server pages (JSPs) set up. The JSP's never seem to work at the same time as the Restlets, should I only be using one or the other in GAE? I'm also using Shiro (formerly Ki, formerly JSecurity) and I have been unable to get Restlets to work with Shiro's filter for authentication. Are there any issues in particular that I should be aware of? What are other people using to secure restlet apps on GAE? Is Shiro overkill if I just need authentication and some role-based authorization? Thanks so much! Chris

  • Finding the second highest number in array

    - by Richard Jackson
    I'm having difficulty to understand the logic behind the method to find the second highest number in array. The method used is to find the highest in the array but less than the previous highest (which has already been found). The thing that I still can't figure it out is why || highest_score == second_highest is necessary. For example I input three numbers: 98, 56, 3. Without it, both highest and second highest would be 98. Please explain. int second highest = score[0]; if (score[i] > second_highest && score[i] < highest_score || highest_score == second_highest) second_highest = score[i];

  • How do you balance business process changes against the challenges of changing software?

    - by Achilles
    In my admittedly young career I've found myself writing code to support quirky business rules and processes. Inevitably these changes were always in some massively difficult code base and caused many issues. My question has a couple of parts: While software is a tool for businesses to make their lives easier, at what point do we as developers suggest a change in business process rather than in the software as the "magic bullet" to solve a particular problem. How do we as developers evangelize a certain level of reverence for the software as well as the difficulty involved in making changes simply to support the quirks of the business? I understand that these changes in business processes promote our industry, but in an analogy my father would understand: Which is easier, to melt down a hammer to forge a screwdriver to drive screws or to simply use nails since your hammer is already awesome...?

  • Is it possible to set properties on a Mock Object in Simpletest

    - by JW
    I normally use getter and setter methods on my objects and I am fine with testing them as mock objects in SimpleTest by manipulating them with code like: Mock::generate('MyObj'); $MockMyObj->setReturnValue('getPropName', 'value') However, I have recently started to use magic interceptors (__set() __get()) and access properties like so: $MyObj->propName = 'blah'; But I am having difficulty making a mock object have a particular property accessed by using that technique. So is there some special way of setting properties on MockObjects. I have tried doing: $MockMyObj->propName = 'test Value'; but this does not seem to work. Not sure if it is my test Subject, Mock, magic Interceptors, or SimpleTest that is causing the property to be unaccessable. Any advice welcome.

  • Linq to Sql Data class in dbml

    - by Simon
    I am abit curious about dbml.... Should I create one dbml file for one database or separated into different parts e.g. User dbml (only tables relate to users) etc? When I do this I will have abit of problems. Assume the User dbml has a User table and if the Order dbml has a User table as well, this won't be allowed if the entity namespace are the same. If I have set a different entity namespace for each of the dbml, it works but this will gives me a different entity of User table. When a single data returns to Business Logic layer, there is a difficulty of knowing which entity namespace of the user table to be used. If I built one dbml file instead of having separate dbml, will single dbml appear slower than the separated dbml version when fetching the data from the database.

  • insertNewObjectForEntityForName: inManagedObjectContext: returning NSNumber bug?

    - by beinstein
    I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. All of a sudden I'm now dumbfounded by an error. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

  • SQL - How can I apply a "semi-unique" constraint?

    - by Erin Drummond
    Hi, I have a (simplified) table consisting of three columns: id INT PRIMARY KEY NOT NULL AUTO_INCREMENT, foreignID INT NOT NULL, name VARCHAR NOT NULL Basically, I would like to add a constraint (at the database level rather than at the application level) where it only possible for one unique 'name' to exist per foreignID. For example, given the data (id, foreignid, name): 1,1,Name1 2,1,Name2 3,1,Name3 4,2,Name1 5,2,Name2 I want the constraint to fail if the user tries to insert another 'Name3' under foreignId 1, but succeed if the user tries to insert 'Name3' under foreignId 2. For this reason I cannot simply make the whole column UNIQUE. I am having difficulty coming up with a SQL expression to achieve this, can anybody help me? Thanks

  • SlideDown then call custom function

    - by user275074
    Hi, Having difficulty understanding why my function is being called twice. I'm trying to detect when a radio button is called (intRev_yes), check if a div is empty, slide down another div and then call a custome function which dynamically creates a date field. if(this.id=="intRev_yes"){ if($('div#mainField').is(':empty')){ $('.intRevSections').slideDown('slow',function(){ current=-1; addIrField(); }); } } When I alert out at each stage, after getting to the end (i.e. addIrField()), the script seems to go back to the slideDown() section and recalls addIrField(). I can't understand why, there are no loops. current is used as an index for the date field.

  • Stop propagating deletes

    - by Mark
    Is it just me or is anyone else finding EF very difficult to use in a real app :( I'm using it as the data layer and have created custom business objects. I'm having difficulty converting the business objects back to EF objects and updating/adding/deleting from the database. Does anyone know a good, simple example of doing this? Actually the current problem that's driving me nuts is when I delete something EF tries to delete other related stuff as well. For example, if I delete an invoice it will also delete the associated customer! Seems odd. I can't figure out how to stop it doing this. // tried: invoiceEfData.CustomerReference = null; // also tried invoiceEfData.Customer = null; context.DeleteObject(invoiceEfData); context.SaveChanges(); // at this point I get a database error due to it attempting to delete the customer

  • Graceful handling of server timeout in BlazeDS

    - by Rydell
    I have a flex client that makes service calls to a tomcat server running BlazeDS. I would like to gracefully handle server session timeouts in this environment. I do have security constraints on the service, so the client authenticates against a remote object by initializing a ChannelSet based on the destination, and then logging in using that ChannelSet. After the user is authenticated, if they go get a (long) cup of coffee, their session will inevitably time out. I would like the client to detect the timeout, and return the user back to the login page, with the appropriate informational messages. But I am having difficulty finding the best way to detect this timeout from the client. Is it possible, or must I have the server throw an error when the timeout occurs? Thanks!

  • What is a TFS Agile Issue?

    - by Jaxidian
    With TFS2010 using the "MSF for Agile Software Development v5" process template, I'm having some difficulty in understanding exactly what an Issue is. The most specific documentation I've been able to find is this. Is an Issue a higher-level item for which we will probably generate a Bug for after some investigation in code/requirements? Or is an Issue something different than a Bug because it has not actually a mistake in code but is more of a critical oversight in design (for example, there was never an attempt to create a datepicker for all date fields and this is a UX issue but not really a bug) and therefore a change request of sorts? Or is it something different?

  • Sharepoint checkin/checkout

    - by Prashanth
    We have a sharepoint based application that uses a custom database for storing metadata/files (which could also be on a file share) My question is how can the standard file checkin/check out option in document library be customized? The javascript file ows.js in the layouts folder contains the functions that provide checkin/check out/ open file functionality. Behind the scenes it relies on a combination of HTTP Post/GET methods + SOAP + an activeX control to achieve the desired functionality. Customizing these javascript function seems tedious/error prone. Note that we have a web service that exposes endpoints, for retrieving necessary file information/data from the backend. The difficulty is in integrating it with the sharepoint js functions, due to lack of proper documentation. (Also the js functions might change over different versions of sharepoint) Also is it possible to create files/open files etc from the cache area on the client machine from server side code?
