    - by dragonfly

  • What's the proper technical term for "high ascii" characters?

    - by moodforaday
    What is the technically correct way of referring to "high ascii" or "extended ascii" characters? I don't just mean the range of 128-255, but any character beyond the 0-127 scope. Often they're called diacritics, accented letters, sometimes casually referred to as "national" or non-English characters, but these names are either imprecise or they cover only a subset of the possible characters. What correct, precise term that will programmers immediately recognize? And what would be the best English term to use when speaking to a non-technical audience?

  • database vs flat file, which is a faster structure for "regex" matching with many simultaneous reque

    - by Jamex
    Hi, which structure returns faster result and/or less taxing on the host server, flat file or database (mysql)? Assume many users (100 users) are simultaneously query the file/db. Searches involve pattern matching against a static file/db. File has 50,000 unique lines (same data type). There could be many matches. There is no writing to the file/db, just read. Is it possible to have a duplicate the file/db and write a logic switch to use the backup file/db if the main file is in use? Which language is best for the type of structure? Perl for flat and PHP for db? Addition info: If I want to find all the cities have the pattern "cis" in their names. Which is better/faster, using regex or string functions? Please recommend a strategy TIA

  • Creating New Objects in JavaScript

    - by Ken Ray
    I'm a relatively newbie to object oriented programming in JavaScript, and I'm unsure of the "best" way to define and use objects in JavaScript. I've seen the "canonical" way to define objects and instantiate a new instance, as shown below. function myObjectType(property1, propterty2) { this.property1 = property1, this.property2 = property2 } // now create a new instance var myNewvariable = new myObjectType('value for property1', 'value for property2'); But I've seen other ways to create new instances of objects in this manner: var anotherVariable = new someObjectType({ property1: "Some value for this named property", property2: "This is the value for property 2" }); I like how that second way appears - the code is self documenting. But my questions are: Which way is "better"? Can I use that second way to instantiate a variable of an object type that has been defined using the "classical"way of defining the object type with that implicit constructor? If I want to create an array of these objects, are there any other considerations? Thanks in advance.

  • How do I draw an ESB on a SoaML diagram?

    - by dave
    I've recently had to draw some architectural diagrams that feature the use of an Enterprise Service Bus. The ESB is critical, so everyone wants it to show up on the diagram. But since it's the center of what everything is connected to, it really of gets in the way. I settled on trying to use SoaML. I color-coded the request points blue and service points green, to help then stand out. The text names on the ports give you a sense of what talks to what, and it's incredibly obvious that everything goes through the ESB. Can anyone comment on my approach? Any suggestions on something better?

  • Rotation of two objects in relation

    - by DMan
    I've got a two sprites- I'll say I have a swing and a person. The swing 'swings' back and forth as I passed a rotation variable into spriteBatch.Draw(). Now I want my person to 'sit' on the swing, and am not sure of how to approach it. Since I want a relative to the swing sprite, I tried personPos=swingPos, but that obviously doesn't work as the swing's position is always the same (it's anchored to a point and swings from there). How would I make the person sprite follow the swinging part of the swing sprite, if that makes any sense?

  • Java: How do you access a sub-object of an object with no "getXXX" method to that sub-object

    - by Daxon
    I'll explain with pictures from Eclipse Debugger I have an Class called "FieldContext", (I can't edit it, it's compiled in the Java OVal API) Within "FieldContext" on the eclipse variable tab are "CompileTimeType" and "field" Q1 Is there a legend for the icons in the variables tab? like what the red box with the "F" means + yellow diamond boxes? Now I want to access the fields inside the "field" object (RedBox) .. preferably "name" But the "FieldContext" does not have a "getField()" method, yet it has a "getCompileTimeType()" method. Q2 So is there anyway to get that field object being a "SerializableField" Class from the "FieldContext"? If eclipse debugger can see/get/edit them then I hope I can do the same in Java.

  • Why is the proper "respond_to" format not getting called?

    - by humble_coder
    Hi All, I'm having a bit of an odd issue. Really too odd to type out, but here goes. Basically I have a controller that refuses to "respond_to" using javascript unless I assign my "chart.generate_xml" to a variable before the "respond_to" block like so: @xml = @chart.generate_xml(@begin_date,@end_date,1.hour) respond_to do |format| format.html format.js{ render :update do |page| page.insert_html :bottom, "chart-div", @xml #page.insert_html :bottom, "chart-div", @chart.generate_xml(@begin_date,@end_date,1.hour) end } If I remove the upper "@xml= …" portion and go with the lower "page.insert", the "format.js" section doesn't get called. And if I try to force the format with "request.format = :js", I get the javascript returned as text. I'm not doing anything special here in that method call, so I'm not sure why it would choose to respond any differently. FWIW, the method that triggers this controller action is using JS to do so, so I'm confused as to why "format.js" isn't always getting called. Thoughts? Best.

  • Update JProgressBar from new Thread

    - by Dacto
    How can I update the JProgressBar.setValue(int) from another thread? My secondary goal is do it in the least amount of classes possible. Here is the code I have right now: **Part of the main class....** pp.addActionListener( new ActionListener(){ public void actionPerformed(ActionEvent event) { new Thread(new Task(sd.getValue())).start(); } }); public class Task implements Runnable{ int val; public Task(int value){ this.val = value; } @Override public void run() { for (int i=0; i<=value; i++){ //Progressively increment variable i pbar.setValue(i); //Set value pbar.repaint(); //Refresh graphics try{Thread.sleep(50);} //Sleep 50 milliseconds catch (InterruptedException err){} } } } pp is a JButton and starts the new thread when the JButton is clicked. pbar is the JProgressBar object from the Main class. How can I update its value?(progress) The code above in run() cannot see the pbar.

  • How to check whether the form has any ShowDialog() forms open?

    - by kornelijepetak
    I have a form MainForm with several properties/methods that are accessed from another thread. At some point I might open a form AuxForm with ShowDialog() and then while that modal form is open, the other thread still modifies the MainForm's properties. This is all desired. In one of the methods accessed from another thread I need to execute some code, but only if the modal AuxForm is not open. Is there any way to check this (by using .NET WF Form properties) or I need to use a flag variable? NOTE: None of these properties/methods modify the controls (so no Invoke is required).

  • Developing "Command Line" in .NET?

    - by Sergey Malyan
    Imagine a "search box" on the right top side of the UI Windows Application. When user types a desired action, a matching functionality is executed. Screen gets opened, or action gets performed. For example: user types "create" and intellisence offered next word options "client"/"product", user picks "client", and "Create New Client" screen opens up. So what I am looking for if there is a framework support for this. I assume that framework shall bind together text commands names, commands and show in intellisense. Same framework possibly could have been used in alternative "Command Line interface". I recall Microsoft had some recent framework that helps to setup "command Line Interface" environmental. It is hard to search on web for this keywords, so relying on intelligent help from you guys. Thanks in advance.

  • SQL Server Import table keeping default values

    - by Chrissi
    I am importing a table from one database to another in SQL Server 2008 by right-clicking the target database and choosing Tasks Import Data... When I import the table I get the column names and types and all the data fine, but I lose the primary key, identity specifications and all the default values that were set in the source table. So now I have to set all the default values for each column again manually. Is there any way to get the default values with the import, or even after with a Query? I am VERY new to this and flailing in the dark, so forgive me if this is a really stupid question...

  • How to perform COUNT() or COUNT(*)

    - by ninumedia
    I have a list of tags in a database. Ex: villan hero spiderman superman superman I wanted to obtain a sorted list of the tag names in ascending order and the number of times the unique tag appeared in the database. I wrote this code: Ex: SELECT hashtag.tag_name, COUNT( * ) AS number FROM hashtag GROUP BY hashtag.tag_name ORDER BY hashtag.tag_name ASC This yields the correct result: hero - 1 spiderman - 1 superman - 2 villan - 1 How can I obtain the full COUNT of this entire list. The answer should be 4 in this case because there are naturally 4 rows. I can't seem to get a correct COUNT() without the statement failing. Thanks so much for the help! :)

  • Rerversing AND Bitwise.

    - by Benjamin
    Hey all, Here's the following algorithm: int encryption(int a, int b) { short int c, c2; uint8_t d; c = a ^ b; c2 = c; d = 0; while(c) { c &= c - 1; d++; } return d; } How can I find which variable a and b I should send in that function to decide of the output value of d? In other words, how can I reverse the algoritm to let's say if I want d=11?

  • My object becomes NSCFArray when running on iPhone

    - by cagreen
    I'm really scratching my head on this one: I have an object (MyObject) which I instantiate, and this object has an NSArray member variable. The following simple code working in the sim: MyObject *myObj = [[MyObject alloc] init]; NSArray *arr = [myObj myMemberArray]; When I hover over myObj in XCode the tooltip reads "MyObject". Good! But when I debug it on the device (OS 3.1.3) I get: "[NSCFArray myMemberArray]: unrecognized selector sent to instance ... " When I hover over myObj, sure enough it reads "NSCFArray". Can anyone give me some pointers on where to go next with this? Thanks.

  • gethostbyname in C

    - by Matic
    I don't know how to write applications in C, but I need a tiny program that does: lh = gethostbyname("localhost"); output = lh->h_name; output variable is to be printed. The above code is used in PHP MongoDB database driver to get the hostname of the computer (hostname is part of an input to generate an unique ID). I'm skeptical that this will return the hostname, so I'd like some proof. Any code examples would be most helpful. Happy day, Matic

  • Loading textures in an Android OpenGL ES App.

    - by Omega
    I was wondering if anyone could advise on a good pattern for loading textures in an Android Java & OpenGL ES app. My first concern is determining how many texture names to allocate and how I can efficiently go about doing this prior to rendering my vertices. My second concern is in loading the textures, I have to infer the texture to be loaded based on my game data. This means I'll be playing around with strings, which I understand is something I really shouldn't be doing in my GL thread. Overall I understand what's happening when loading textures, I just want to get the best lifecycle out of it. Are there any other things I should be considering?

  • gem install cannot find a header file

    - by Milktrader
    Following along the github README for talib_ruby: sudo port install ta-lib Complete. Next is where the trouble begins. sudo env ARCHFLAGS="-arch PLATFORM" gem install talib_ruby -- --with-talib-include=ABSOLUTE_PATH_TO_TALIB_HEADERS --with-talib-lib=ABSOLUTE_PATH_TO_TALIB_LIBS This install fails I believe because apparently it cannot find the ta_abstract.h file talib.c:2:25: error: ta_abstract.h: No such file or directory . . . many more errors I have included in my .bash_profile file the following: export ABSOLUTE_PATH_TO_TALIB_HEADERS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/include/ta-lib export ABSOLUTE_PATH_TO_TALIB_LIBS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/lib And indeed the ta_abstract.h file is located where I'm saying in the ABSOLUTE_PATH variable assignment. What gives?

  • Maximum Possible File Name Length in Windows Kernel

    - by Lambert
    I was wondering, what is the longest possible name length allowed by the Windows kernel? E.g.: I know the kernel uses UNICODE_STRING structures to hold all object paths, and since the byte length of a wide-character string is stored inside a USHORT, that allows for a maximum path length of 2^15 - 1 characters. Is there a similar, hard restriction on a file name (rather than path)? (I don't care if NTFS or FAT32 imposes a particular restriction; I'm looking for the longest possible theoretically allowed name in the kernel, assuming no additional file system or shell restrictions.) (Edit: For those wondering why this even matters, consider that normally, traversing a directory is achieved by FindFirstFile/FindNextFile calls, one call per file. Given the function named NtQueryDirectoryFile, which is the underlying system call and which returns multiple file names per call, it's actually possible to take advantage of this maximum-length restriction on the path to make an extremely-fast directory traverser that uses solely the stack as a buffer. Now I'm trying to extend that concept, and I need to know the maximum size of a file name.)
