  • How do I add programmatically-generated new files to source control?

    - by Alex Basson
    This is something I've never really understood about source control, specifically Subversion (the only source control I've ever used, which isn't saying much). I'm considering moving to git or Mercurial, so if that affects the answer to my question, please indicate as such. Ok. As I understand it, every time I create a new file, I have to tell SVN about it, so that it knows to add it to the repository and place it under control. Something like: svn add newfile That's fine if I'm the one creating the file: I know I created it, I know its name, I know where it lives, so it's easy to tell SVN about it. But now suppose I'm using a framework of some kind, like Rails, Django, Symfony, etc., and suppose I've already done the initial commit. All of these frameworks create new files programmatically, often many at once, in different directories, etc. etc. How do I tell the source control about these new files? Do I have to hunt each one of them down individually and add them? Is there an easier way? (Or am I possibly misunderstanding something fundamental about source control?)

  • SQL Joining Two or More from Table B with Common Data in Table A

    - by Matthew Frederick
    The real-world situation is a series of events that each have two or more participants (like sports teams, though there can be more than two in an event), only one of which is the host of the event. There is an Event db table for each unique event and a Participant db table with unique participants. They are joined together using a Matchup table. They look like this: Event EventID (PK) (other event data like the date, etc.) Participant ParticipantID (PK) Name Matchup EventID (FK to Event table) ParicipantID (FK to Participant) Host (1 or 0, only 1 host = 1 per EventID) What I'd like to get as a result is something like this: EventID ParticipantID where host = 1 Participant.Name where host = 1 ParticipantID where host = 0 Participant.Name where host = 0 ParticipantID where host = 0 Participant.Name where host = 0 ... Where one event has 2 participants and another has 3 participants, for example, the third participant column data would be null or otherwise noticeable, something like (PID = ParticipantID): EventID PID-1(host) Name-1 (host) PID-2 Name-2 PID-3 Name-3 ------- ----------- ------------- ----- ------ ----- ------ 1 7 Lions 8 Tigers 12 Bears 2 11 Dogs 9 Cats NULL NULL I suspect the answer is reasonably straightforward but for some reason I'm not wrapping my head around it. Alternately it's very difficult. :) I'm using MYSQL 5 if that affects the available SQL.

  • IPhone sdk, more accurate collision detection and set the frame/bounds of UIImageView...

    - by Harry
    Hey, Im having a big problem with my app at the moment, its all too inaccurate. I have a image of a ballooon, https://dl.dropbox.com/u/2578642/Balloonedit.png And i have a dart which if it collides into the balloon the game ends. At the moment i am populating the image of the balloon with 8 UIImageViews. and i am detecting if the dart hits them, this was suppose to make it really accurate but its not, the dart pretty much passes through the balloon when its meant to collide, so i have a plan, is there any way to detect when the dart hits the actual image of the balloon not the UIImageView, or is there any way to draw a border around the balloon and detect if it hits that? currently i am using this code to detect the collision: if (CGRectIntersectsRect(pinend.frame, balloonbit1.frame)){ [maintimer invalidate]; accelManeger.delegate = nil; [ball setImage:img]; [UIImageView beginAnimations:nil context:NULL]; [UIImageView setAnimationDuration:0.3]; ball.transform = CGAffineTransformMakeScale(2, 2); [UIImageView commitAnimations]; } So in one method there are 40 of these bits of code and as you can imagine it is not very accurate/fast to respond. So like i said is there a way to draw a border or something around the balloon and detect the collision between the border and dart? Because then i would imagine it would run a lot smother because it would only have to process 5 bits of code. Thanks for any help. This is a big Question so if you can answer it i will buy your app :) Cheers, Harry :/

  • Photoshop CS5 not recognising activeDocument

    - by Max Kielland
    I wrote a quite big script for Photoshop CS5.1 on my 64bit Vista machine. Now when I run the very same script on my new 64bit Windows 7 machine, Adobe ExtendScript Tool complains about activeDocument (no such element) in this simple script: #target photoshop var pDoc = app.activeDocument; alert("Done!"); I have tried both and without #target and choosing the target in the ExtendedScript Tool. Is there something I have missed, or do I need to install something more. I only installed the 64bit version of Photoshop. Is it so that the 32bit Photoshop has the script extensions? I don't see why I need to install both 32bit and 64bit versions if I'm only going to use the 64bit version. EDIT I installed the 32bit version as well. Tried the same script against 32 and 64 bit, still no difference. SOLVED The mystery is solved. It is embarrassing simple if you interpret the error message more careful. Of course I can't get an activeDocument if there are no documents in Photoshop, duh!?! I interpreted it as the statement activeDocument wasn't recognised, but of course if I have no document there is no such element (as a photoshop document) to give me. I'm used to C++ and would expect the reuslt to be a NULL value or similar if there is a problem to get the document... excuses, excuses ;) Well, if someone else should get into the same problem, here is the answer on my expense :D

  • svcutil, XmlSerializer and xsd:list

    - by Dmitry Ornatsky
    I'm using svcutil to generate classes from service metadata. This XML schema <xsd:complexType name="FindRequest"> ... <xsd:attribute name="Significance" type="Significance" use="optional" /> </xsd:complexType> <xsd:simpleType name="Significance"> <xsd:list> <xsd:simpleType> <xsd:restriction base="xsd:int"> <xsd:enumeration value="1" /> <xsd:enumeration value="2" /> <xsd:enumeration value="3" /> </xsd:restriction> </xsd:simpleType> </xsd:list> produces following code: public partial class FindRequest { ... private int significanceField; private bool significanceFieldSpecified; [System.Xml.Serialization.XmlAttributeAttribute()] public int Significance { get { return this.significanceField; } set { this.significanceField = value; } } [System.Xml.Serialization.XmlIgnoreAttribute()] public bool SignificanceSpecified { get { return this.significanceFieldSpecified; } set { this.significanceFieldSpecified = value; } } } My questions are: Is it possible to make XmlSerializer understand this type of list: <FindRequest Significance="1 2 3"/> For example by using some kind of a flags-style enum: public enum EmployeeStatus { [XmlEnum(Name = "1")] One = 1, [XmlEnum(Name = "2")] Two = 2, [XmlEnum(Name = "3")] Three = 4 } If the answer is yes, Is it possible to make svcutil/xsd.exe generate classes that are serialized that way without changing the schema?

  • What is the correct way to implement a massive hierarchical, geographical search for news?

    - by Philip Brocoum
    The company I work for is in the business of sending press releases. We want to make it possible for interested parties to search for press releases based on a number of criteria, the most important being location. For example, someone might search for all news sent to New York City, Massachusetts, or ZIP code 89134, sent from a governmental institution, under the topic of "traffic". Or whatever. The problem is, we've sent, literally, hundreds of thousands of press releases. Searching is slow and complex. For example, a press release sent to Queens, NY should show up in the search I mentioned above even though it wasn't specifically sent to New York City, because Queens is a subset of New York City. We may also want to implement "and" and "or" and negation and text search to the query to create complex searches. These searches also have to be fast enough to function as dynamic RSS feeds. I really don't know anything about search theory, or how it's properly done. The way we are getting by right now is using a data mart to store the locations the releases were sent to in a single table. However, because of the subset thing mentioned above, the data mart is gigantic with millions of rows. And we haven't even implemented cities yet, and there are about 50,000 cities in the United States, which will exponentially increase the size of the data mart by so much I'm afraid it just won't work anymore. Anyway, I realize this is not a simple question and there won't be a "do this" answer. However, I'm hoping one of you can point me in the right direction where I can learn about how massive searches are done? Because I really know nothing about it. And such a search engine is turning out to be incredibly difficult to make. Thanks! I know there must be a way because if Google can search the entire internet we must be able to search our own database :-)

  • Check if UINavigationItem title is truncated

    - by PartiallyFinite
    I want to check whether the title of a UINavigationItem is truncated. I set the title like this: self.navigationItem.title = whatever. I know I can check if the text in a UILabel is truncated like this: CGSize size = [label.text sizeWithFont:[UIFont fontWithName:@"myfont" size:18.0]]; if (size.width > label.bounds.size.width) { // set a shorter title } And I can even find the UINavigationItemView object in which the title is displayed like so: UIView *navItemView; for (UIView *view in self.navigationController.navigationBar.subviews) { if ([view isKindOfClass:NSClassFromString(@"UINavigationItemView")]) { navItemView = view; } } But I cannot apply this method to the navItemView because is always seems to have a width of exactly 58, which is much less than the title in it, so according to that, it would appear that the title is truncated, even when it isn't. So, my question comes down to this: How do I find the width of the title displayed in the UINavigationItem? UPDATE: I have found a solution to my problem, but it isn't exactly ideal, perfect, or reliable, so I am not marking it as an answer yet. If anyone has any better solutions, please share them.

  • Parse XML function names and call within whole assembly

    - by Matt Clarkson
    Hello all, I have written an application that unit tests our hardware via a internet browser. I have command classes in the assembly that are a wrapper around individual web browser actions such as ticking a checkbox, selecting from a dropdown box as such: BasicConfigurationCommands EventConfigurationCommands StabilizationCommands and a set of test classes, that use the command classes to perform scripted tests: ConfigurationTests StabilizationTests These are then invoked via the GUI to run prescripted tests by our QA team. However, as the firmware is changed quite quickly between the releases it would be great if a developer could write an XML file that could invoke either the tests or the commands: <?xml version="1.0" encoding="UTF-8" ?> <testsuite> <StabilizationTests> <StressTest repetition="10" /> </StabilizationTests> <BasicConfigurationCommands> <SelectConfig number="2" /> <ChangeConfigProperties name="Weeeeee" timeOut="15000" delay="1000"/> <ApplyConfig /> </BasicConfigurationCommands> </testsuite> I have been looking at the System.Reflection class and have seen examples using GetMethod and then Invoke. This requires me to create the class object at compile time and I would like to do all of this at runtime. I would need to scan the whole assembly for the class name and then scan for the method within the class. This seems a large solution, so any information pointing me (and future readers of this post) towards an answer would be great! Thanks for reading, Matt

  • Binding data to the custom DataGridView

    - by Jatin Chaturvedi
    All, I have a customized DataGridView where I have implemented extra functionality and bounded datasource in the same custom DataGridView (Using C# and .NET). Now, I could able to use it properly by placing it on a panel control. I have added label as button on panel control to display data from datasource on to datagrid and create a binding source. Another Label which act as a button is used to update data from grid to databse. Issue: I pressed show label to display data in a dsatagridview. Modified the grid cell value and immediately pressed update label which is on same panel control. I observed that, the cursor is still in the grid cell when I press Save button. While saving, the cell value is null even though I have entered something in the presentation layer. My expected behaviour is to get the modified value while saving. Special Case: After typing something in the grid cell, if I click on somewhere else like the row below where I entered something, before I click on Save button, it is working fine. (Here, mainly I tried to remove the focus from the currently modified cell) Is there any way to bind sources before I click on save button? Please suggest me. Please feel free to ask me if you need any information. I have also seen same kind of problem on this forum, but unfortunately the author got the answer and didnt post it back. here is that URL: http://social.msdn.microsoft.com/Forums/en/winformsdesigner/thread/54dcc87a-adc2-4965-b306-9aa9e79c2946 Please help me.

  • Sending email through a Google Apps account is working locally, but not on my web server...

    - by Janis Baldwin
    Related: Send Email via C# through Google Apps account My question is the same so I implemented Koistya's solution as follows. The heartbreak is that it works beautifully on my dev laptop but when ported to web server it times out with no explanation. My SMTP config is in my web.config file. I made mods based on Koistya's answer: <mailSettings> **Changed** <smtp from="[email protected]"> <network host="smtp.gmail.com" password="[password]" port="587" userName="[email protected]"/> </smtp> **Original** <!--<smtp from="[email protected]"> <network host="mail.domain.com" password="[password]" port="25" userName="[email protected]"/> </smtp>--> </mailSettings> My .Net C# code (before & after removed): SmtpClient mSmtpClient = new SmtpClient(); mSmtpClient.EnableSsl = true; mSmtpClient.Send(message); As I said this works great on my dev environment but not on web. Can anyone help? Thanks.

  • Why does output of fltk-config truncate arguments to gcc?

    - by James Morris
    I'm trying to build an application I've downloaded which uses the SCONS "make replacement" and the Fast Light Tool Kit Gui. The SConstruct code to detect the presence of fltk is: guienv = Environment(CPPFLAGS = '') guiconf = Configure(guienv) if not guiconf.CheckLibWithHeader('lo', 'lo/lo.h','c'): print 'Did not find liblo for OSC, exiting!' Exit(1) if not guiconf.CheckLibWithHeader('fltk', 'FL/Fl.H','c++'): print 'Did not find FLTK for the gui, exiting!' Exit(1) Unfortunately, on my (Gentoo Linux) system, and many others (Linux distributions) this can be quite troublesome if the package manager allows the simultaneous install of FLTK-1 and FLTK-2. I have attempted to modify the SConstruct file to use fltk-config --cflags and fltk-config --ldflags (or fltk-config --libs might be better than ldflags) by adding them like so: guienv.Append(CPPPATH = os.popen('fltk-config --cflags').read()) guienv.Append(LIBPATH = os.popen('fltk-config --ldflags').read()) But this causes the test for liblo to fail! Looking in config.log shows how it failed: scons: Configure: Checking for C library lo... gcc -o .sconf_temp/conftest_4.o -c "-I/usr/include/fltk-1.1 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT" gcc: no input files scons: Configure: no How should this really be done? And to complete my answer, how do I remove the quotes from the result of os.popen( 'command').read()? EDIT The real question here is why does appending the output of fltk-config cause gcc to not receive the filename argument it is supposed to compile?

  • How to run R through PHP with exec?

    - by dkar
    I am going to ask something, that I know that it has been asked already some times. But since, all of the past posts are quite old and none of them answer my problem..I try again. I am completely new in R language and relative new in php. What I want to do is to use the exec() function from php in order to execute a R script. Most of the people here will start talking about rapache, rserve and I don't know what else..but since I am not familiar with all these technologies, I prefer just using exec. The code I will show here is working just fine when I run it with Rscript from the terminal. # R script png("temp.png") plot(5,5) dev.off() But when I try to run it either with Rscript or with R CMD BATCH from PHP, like this: echo exec("Rscript my_rscript.R"); //OR //echo exec("R CMD BATCH my_rscript.R"); I get nothing back. I have checked if exec() function is available and if it works. Everything is ok with this. I read also, that I might have to change the permissions of the webserver...but I don't know how to do this in mamp. I hope I am clear with my problem and someone can help. Thanks Dimitris

  • Working around "one executable per project" in Visual C# for many small test programs

    - by Kevin Ivarsen
    When working with Visual Studio in general (or Visual C# Express in my particular case), it looks like each project can be configured to produce only one output - e.g. a single executable or a library. I'm working on a project that consists of a shared library and a few application, and I already have one project in my solution for each of those. However, during development I find it useful to write small example programs that can run one small subsystem in isolation (at a level that doesn't belong in the unit tests). Is there a good way to handle this in Visual Studio? I'd like to avoid adding several dozen separate projects to my solution for each small test program I write, especially when these programs will typically be less than 100 lines of code. I'm hoping to find something that lets me continue to work in Visual Studio and use its build system (rather than moving to something like NAnt). I could foresee the answer being something like: A way of setting this up in Visual Studio that I haven't found yet A GUI like NUnit's graphical runner that searches an assembly for classes with defined Main() functions that you can select and run A command line tool that lets you specify an assembly and a class with a Main function to run

  • NonStop ODBC: how the connections (ODBC servers) are assigned to CPUs?

    - by Vladimir Dyuzhev
    We have an ODBC pool running on a NonStop server. The pool is connected to SQL/MX. This pool is used by a few external Java applications, each of which has an JDBC pool connected to ODBC pool (e.g. 14 connections per application). With time (after a few application recycles) we see an imbalance between CPUs -- some have 8 ODBC processes running, some only 5. That leads to CPU time imbalance too. Up to this point we assumed that a CPU is assigned to ODBC process in round-robin fashion. That would maintain the number of ODBC processes more or less equally distributed. It's not the case though. Is there any information on how ODBC pool decided which CPU to choose for every new allocated process? Does it look at CPU load? Available memory? Something else? Sadly, even HP's own people (available to us, that is) couldn't answer those questions with certainty. :-(

  • Comparing two collections for equality

    - by Crossbrowser
    I would like to compare two collections (in C#), but I'm not sure of the best way to implement this efficiently. I've read the other thread about Enumerable.SequenceEqual, but it's not exactly what I'm looking for. In my case, two collections would be equal if they both contain the same items (no matter the order). Example: collection1 = {1, 2, 3, 4}; collection2 = {2, 4, 1, 3}; collection1 == collection2; // true What I usually do is to loop through each item of one collection and see if it exists in the other collection, then loop through each item of the other collection and see if it exists in the first collection. (I start by comparing the lengths). if (collection1.Count != collection2.Count) return false; // the collections are not equal foreach (Item item in collection1) { if (!collection2.Contains(item)) return false; // the collections are not equal } foreach (Item item in collection2) { if (!collection1.Contains(item)) return false; // the collections are not equal } return true; // the collections are equal However, this is not entirely correct, and it's probably not the most efficient way to do compare two collections for equality. An example I can think of that would be wrong is: collection1 = {1, 2, 3, 3, 4} collection2 = {1, 2, 2, 3, 4} Which would be equal with my implementation. Should I just count the number of times each item is found and make sure the counts are equal in both collections? The examples are in some sort of C# (let's call it pseudo-C#), but give your answer in whatever language you wish, it does not matter. Note: I used integers in the examples for simplicity, but I want to be able to use reference-type objects too (they do not behave correctly as keys because only the reference of the object is compared, not the content).

  • How can I setup ANT with Subversion and ColdFusion Builder (eclipse) to check out a local build to w

    - by Smooth Operator
    I am not sure if there's an answer for this already -- couldn't find one for this (hopefully common) setup: I recently converted one of my ColdFusion projects to deploy via ANT. I have a local ant script that instructs a remote server to check out the code, and run the application's specific build file, remotely on the server. I have a few endpoints: Live - production (on the production server) Staging - on the production server, different datasource, etc. dev - on the local box. What I have run into it seems is a simple and common problem. I now need ANT to create any build, even locally. Fine, created a local endpoint and it configures for my box. Issue? How do I get it to show up as a project (automatically if possible) in Eclipse/ColdFusion builder. What I envision is instead of checking out a branch via the subversion plugin in CFBuilder/Eclipse, I now use ANT to do that for me. Since I use ColdFusion Builder (Eclipse + Adobe's plugin), I have all of eclipse's tools and plugins available to solve the problem of : how can I best call ANT from within Eclipse/ColdFusion Builder, to setup the local build as a project that I can develop and work on? I think when I check the code back in from the local box, I'd have to be sure not to check in any files with local config paths, etc. I hope this is a detailed and clear enough explanation, if not, please ask. Thanks in advance!

  • Why is MySQL with InnoDB doing a table scan when key exists and choosing to examine 70 times more ro

    - by andysk
    Hello, I'm troubleshooting a query performance problem. Here's an expected query plan from explain: mysql> explain select * from table1 where tdcol between '2010-04-13:00:00' and '2010-04-14 03:16'; +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ | 1 | SIMPLE | table1 | range | tdcol | tdcol | 8 | NULL | 5437848 | Using where | +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ 1 row in set (0.00 sec) That makes sense, since the index named tdcol (KEY tdcol (tdcol)) is used, and about 5M rows should be selected from this query. However, if I query for just one more minute of data, we get this query plan: mysql> explain select * from table1 where tdcol between '2010-04-13 00:00' and '2010-04-14 03:17'; +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ | 1 | SIMPLE | table1 | ALL | tdcol | NULL | NULL | NULL | 381601300 | Using where | +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ 1 row in set (0.00 sec) The optimizer believes that the scan will be better, but it's over 70x more rows to examine, so I have a hard time believing that the table scan is better. Also, the 'USE KEY tdcol' syntax does not change the query plan. Thanks in advance for any help, and I'm more than happy to provide more info/answer questions.

  • Retrieve click() handler in jQuery for later use

    - by Xiong Chiamiov
    I'm using the jQuery tablesorter plugin to sort a table, which assigns .click() handlers to the <th>s in the table. Since my table has alternating colors for each column, I've built a simple fix_table_colors(identifier) function that does as it should when I call it manually using Firebug. I would like, however, to have that automatically called after a sort. To do this, I decided to retrieve the .click() handler from the <th>s, and assign a new handler that simply calls the previous handler, followed by fix_table_colors(). (This SO question is similar, but uses standard onClick() attributes, which won't work here.) From the accepted answer to this question, I have created the following code: $(document).ready(function() { $("table.torrents").tablesorter({ debug: true, headers: { 1: { sorter: 'name' }, 2: { sorter: 'peers' }, 3: { sorter: 'filesize' }, 4: { sorter: 'filesize' }, 5: { sorter: 'filesize' }, 6: { sorter: 'ratio' } } }); $('table.torrents thead th').each(function() { var th = $(this); var clickHandler = th.data('events').click[0]; th.click(function() { clickHandler(); fix_table_colors('table.torrents'); }); }); }); While this is conceptually correct, clickHandler doesn't appear to actually be a function, and so I cannot call it. With a bit more digging in Firebug, I found that click[3] appears to hold the function I'm looking for (and click[10] my new one). I get an 'e is undefined' error on line 2 of tablesorter.min.js when using that, though. Am I even going down the right path? I have a feeling that with what I've found so far, I can make this work, but it's going to be much uglier than I would expect it needs to be.

  • When virtual inheritance IS a good design?

    - by 7vies
    EDIT3: Please be sure to clearly understand what I am asking before answering (there are EDIT2 and lots of comments around). There are (or were) many answers which clearly show misunderstanding of the question (I know that's also my fault, sorry for that) Hi, I've looked over the questions on virtual inheritance (class B: public virtual A {...}) in C++, but did not find an answer to my question. I know that there are some issues with virtual inheritance, but what I'd like to know is in which cases virtual inheritance would be considered a good design. I saw people mentioning interfaces like IUnknown or ISerializable, and also that iostream design is based on virtual inheritance. Would those be good examples of a good use of virtual inheritance, is that just because there is no better alternative, or because virtual inheritance is the proper design in this case? Thanks. EDIT: To clarify, I'm asking about real-life examples, please don't give abstract ones. I know what virtual inheritance is and which inheritance pattern requires it, what I want to know is when it is the good way to do things and not just a consequence of complex inheritance. EDIT2: In other words, I want to know when the diamond hierarchy (which is the reason for virtual inheritance) is a good design

  • MVC Paging and Sorting Patterns: How to Page or Sort Re-Using Form Criteria

    - by CRice
    What is the best ASP.NET MVC pattern for paging data when the data is filtered by form criteria? This question is similar to: http://stackoverflow.com/questions/1425000/preserve-data-in-net-mvc but surely there is a better answer? Currently, when I click the search button this action is called: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Search(MemberSearchForm formSp, int? pageIndex, string sortExpression) {} That is perfect for the initial display of the results in the table. But I want to have page number links or sort expression links re-post the current form data (the user entered it the first time - persisted because it is returned as viewdata), along with extra route params 'pageIndex' or 'sortExpression', Can an ActionLink or RouteLink (which I would use for page numbers) post the form to the url they specify? <%= Html.RouteLink("page 2", "MemberSearch", new { pageIndex = 1 })%> At the moment they just do a basic redirect and do not post the form values so the search page loads fresh. In regular old web forms I used to persist the search params (MemberSearchForm) in the ViewState and have a GridView paging or sorting event reuse it.

  • How to scan an array for certain information

    - by Andrew Martin
    I've been doing an MSc Software Development conversion course, the main language of which is Java, since the end of September. We have our first assessed practical coming and I was hoping for some guidance. We have to create an array that will store 100 integers (all of which are between 1 and 10), which are generated by a random number generator, and then print out ten numbers of this array per line. For the second part, we need to scan these integers, count up how often each number appears and store the results in a second array. I've done the first bit okay, but I'm confused about how to do the second. I have been looking through the scanner class to see if it has any methods which I could use, but I don't see any. Could anyone point me in the right direction - not the answer, but perhaps which library it comes from? Code so far: import java.util.Random; public class Practical4_Assessed { public static void main(String[] args) { Random numberGenerator = new Random (); int[] arrayOfGenerator = new int[100]; for (int countOfGenerator = 0; countOfGenerator < 100; countOfGenerator++) arrayOfGenerator[countOfGenerator] = numberGenerator.nextInt(10); int countOfNumbersOnLine = 0; for (int countOfOutput = 0; countOfOutput < 100; countOfOutput++) { if (countOfNumbersOnLine == 10) { System.out.println(""); countOfNumbersOnLine = 0; countOfOutput--; } else { System.out.print(arrayOfGenerator[countOfOutput] + " "); countOfNumbersOnLine++; } } } } Thanks, Andrew

    - by Cawas
    Similar questions have been brought (good speed comparison there) on this same subject. Hopefully this question is different and updated to Python 2.6 and 3.0. So far I believe the faster and most compatible method (among different Python versions) is the plain simple + sign: text = "whatever" + " you " + SAY But I keep hearing and reading it's not secure and / or advisable. I'm not even sure how many methods are there to manipulate strings! I could count only about 4: There's interpolation and all its sub-options such as % and format and then there's the simple ones, join and +. Finally, the new approach to string formatting, which is with format, is certainly not good for backwards compatibility at same time making % not good for forward compatibility. But should it be used for every string manipulation, including every concatenation, whenever we restrict ourselves to 3.x only? Well, maybe this is more of a wiki than a question, but I do wish to have an answer on which is the proper usage of each string manipulation method. And which one could be generally used with each focus in mind (best all around for compatibility, for speed and for security). Thanks.

  • Allowing user to edit only the page content and some custom fields in wordpress

    - by GaVrA
    This is the site: http://www.backpackers.rs Using "User Role Editor" i have user group that can only read and edit published pages so i can have as many users as i want in that user group and they all will have only one published page on their own so they can edit only that page. Now, this is how a user in that user group currently is seeing "edit page" page: http://i39.tinypic.com/rwuesh.png What i need is to disable all those things that have a red border around it + something with custom fields. So i need to disable these things for user in that user group: ability to change status of the page entire "Attributes" block is something that he/she must not see or be able to change ability to change something in "Discussion" block he/she shouldnt see "Page revisions" block i need a way to give those users ability to use only some custom fields. Currently we have 6 custom fields, and i want to give these users ability to only use 4 of those custom fields. i need to disable these users from creating new custom fields. I dont need complete answers for these things, something to get me started is really what i need. I have been reading codex a lot, but still didnt find something to help me with this, so basically any answer is more then appreciated!

  • advanced Visual Studio kung-fu test -- Calling functions from the Immediate Window during debugging

    - by kizzx2
    I see some related questions have been asked, but they're either too advanced for me to grasp or lacking a step-by-step guide from start to finish (most of them end up being insider talk of their own experiment results). OK here it is, given this simple program: #include <stdio.h> #include <string.h> int main() { FILE * f; char buffer[100]; memset(buffer, 0, 100); fun(); f = fopen("main.cpp", "r"); fread(buffer, 1, 99, f); printf(buffer); fclose(f); return 0; } What it does is basically print itself (assume file name is main.cpp). Question How can I have it print another file, say foobar.txt without modifying the source code? It has something to do with running it through VS's, stepping through the functions and hijacking the FILE pointer right before fread() is called. No need to worry about leaking resources by calling fclose(). I tried the simple f = fopen("foobar.txt", "r") which gave CXX0017: Error: symbol "fopen" not found Any ideas? Edit I found out the solution accidentally on Debugging Mozilla on Windows FAQ. The correct command to put into the Immediate Window is f = {,,MSVCR100D}fopen("foo.txt", "r") However, it doesn't really answer this question: I still don't understand what is going on here. How to systematically find out the {,,MSVCR100D} part for any given method? I know the MSVCR version changes from system to system. How can I find that out? Could anyone explain the curly brace syntax, especially, what are those two commas doing there? Are there more hidden gems using this syntax?

  • Autorotation and multiple view controllers

    - by alku83
    I'm creating an iPad application which should only work in portrait and portait upsidedown modes. For performance reasons in my applicationDidFinishLaunching method I'm creating several viewControllers, and adding them to my main window as subviews. I then hide the ones I don't want to see straight away. There is no tab bar or navigation controller. My problem is that only the first viewController seems to be receiving the rotate calls. I have verified this by swapping around the order in which I add the subviews to the main window and NSLog's. Is there some way I can force all the controllers to receive the calls? Some of my views are designed to lay over the top of another view, but this behind view will not always be the same one - so it seems to make sense to have the overlay view in a separate view controller. Am I doing something fundamentally wrong, and that's why it's not behaving as I would expect? EDIT: The accepted answer for this question seems to indicate the exact problem I'm facing: http://stackoverflow.com/questions/548142/uiviewcontroller-rotate-methods
