• How to I prevent decimal truncation in Word 2003 when a document is auto populated via a Web Service

  - by thomas.loughran

  I have a document template which is being auto populated via an external web service. The incoming data exists as a currency (e.g. 3.10) but when it is passed into the Word Document template the variable is truncated to remove any trailing 0's. I need the number to always appear with 2 decimals, even if they are both 0's. This is with the 2003 version of Word, I have not tested with other versions since all of our document templates need to be generated using that version of Word. I feel like this can be done with a Macro or a VB script but I have a very small amount of time & no experience with these tools - Any help is greatly appreciated!

• Tree position terminology/naming

  - by wst

  This is a naming things question. I am processing trees (XML documents), and there are often special rules applied to nodes based on structure. It's been very difficult coming up with concise naming conventions for some cases, namely for nodes in the first position among their siblings, along with some recursive relationship: Given an arbitrary node, I want to describe its first child, and then that node's first child, and so on recursively. Given another arbitrary node, I want to describe its parent if the parent is first among its siblings, and that parent's parent if it's first, and so on recursively. Is there existing terminology to describe these tree positions? How would you name a variable or function that captures one of these cases so that it's intuitive to an unfamiliar developer trying to understand an algorithm?

• brackets in php templates

  - by Othman

  I have a script, and now it's the perfect time to have an option to change theme templates. I was looking forward to store these files in php files, or html files. with CSS file. I looked over some codes and I found that they use brackets to refer to the variable. Here's an example of a template block: <div class='block_div'> <center>{title}</center> {content} </div> I know that I can use PHP vars usering <?=$var;?>. However, I think the one above is better, and I looked over the web to find anything about it but I couldn't. My Question is how I can use these brackets in my php or html code. to let the user changing the template only not the code!

• Error installing Package Control for Sublime Text 3 on Ubuntu 14.04

  - by user1837378

  This is the error. It comes up when I paste and enter the installation code (which I get from the Package Control website) and each time I open up Sublime Text. Package Control Your system's locale is set to a value that can not handle non-ASCII characters. Package Control can not properly work unless this is fixed. On Linux, please reference your distribution's docs for information on properly setting the LANG environmental variable. As a temporary work-around, you can launch Sublime Text from the terminal with: LANG=en_US.UTF-8 sublime_text I had the same problem with Ubuntu 13.04 so it's probably not version-dependent.

• Box2D platformer movement. Should i mess with velocity?

  - by Romeo

  I have a platformer game in which I implemented the movement using a wheel attached to the hero. For jumping I use this: player.body.applyLinearImpulse(new Vec2(0, 30000000), player.body.getPosition()); The problem is that the xVelocity doesn't remain the same during the jump so it isn't looking natural. Is there any way to modify only the x velocity of the body so that before jumping I store it in a variable and after jumping I apply it to the body? I hope you understand what I am trying to say.

• What are the pros and cons of a non-fixed-interval update loop?

  - by akonsu

  I am studying various approaches to implementing a game loop and I have found this article. In the article the author implements a loop which, if the processing falls behind in time, skips frame renderings and just updates the game in a loop (the last variant called "Constant Game Speed independent of Variable FPS"). I do not understand why it is acceptable to call update_game() in a loop without making sure the update function is called at a particular interval. I do not see any value in doing this. I would think that in my game I want to be sure the game is updated periodically with a known period. So maybe it is worthwhile to have two threads, one would call update periodically, and the other one would redraw the game, also periodically? Would this be a good and practical approach? Of course I would need to synchronise the threads.

• Windows Azure : quand le Cloud vend des avions, Boeing utilise la plate-forme de Microsoft pour modéliser ses appareils

  Windows Azure : quand le Cloud vend des avions Boeing utilise la plate-forme de Microsoft pour modéliser ses appareils Lors du PDC (une de ses conférences pour développeurs) de l'année dernière, Microsoft avait illustré la puissance de calcul de Windows Azure par une démonstration ludique et très concrète. Les studios Pixar étaient montés sur scène pour montrer comment ils utilisaient un nombre variable d'instances hébergées pour obtenir le rendu de certaines scènes de leurs films. Un rendu qu'ils n'auraient pu obtenir, ou pas aussi rapidement, avec leurs propres outils internes. [IMG]http://ftp-developpez.com/gordon-fowler/AzurePixar.jpg[/IMG] P...

• How can I edit (in MS Expression Web ) FrontPage Site Parameters (Substitutions)?

  - by Clay Nichols

  Or, asked another way: Where are the values for MS Front Page Substitions (Site Parameters) stored? (so that I can edit in Web Expressions) Background I'm ashamed to admit that I've been maintaining our company's website in MS FrontPage for over 9 years. I'm moving it to Expression Web, which will display the Substitutions (stored as Site Parameters) but I can't figure out where to edit them. I tried searching the source folders for the website (on my development PC) for the name of the parameter (s-Variable=hoursOfOperation) but did not find it (other than in the files it was actually used in.

• How to make my sprite jump properly?

  - by Matthew Morgan

  I'm currently working on a 2D platformer in XNA. I have, however been having some trouble with creating a fully functional jumping algorithm. This is what I have so far: if (keystate.IsKeyDown(Keys.W)) if (onGround = true) //"onground" is true when the collision between the main sprite and the ground is detected { spritePosition.Y = velocity.Y = -5; } So, the problem I am now having is that as soon as the jump starts the variable "onGround" = false and the sprite is brought back the ground by the simple gravity I have implemented. The other problem I have is creating a limit to the height after which the sprite should automatically return to the ground. Any advice or suggestions would be greatly appreciated.

• Using "prevent execution of method" flags

  - by tpaksu

  First of all I want to point out my concern with some pseudocode (I think you'll understand better) Assume you have a global debug flag, or class variable named "debug", class a : var debug = FALSE and you use it to enable debug methods. There are two types of usage it as I know: first in a method : method a : if debug then call method b; method b : second in the method itself: method a : call method b; method b : if not debug exit And I want to know, is there any File IO or stack pointer wise difference between these two approaches. Which usage is better, safer and why?

• Handling array passed to object at creation

  - by cecilli0n

  When creating my object I pass it an array of a row from my database. (everything in the array we will need, disregarding unnecessary elements at sql query level) When I need to access certain array elements from within my class, I do so like $this->row['element'] However, As I continue development, I sometimes forget what exactly is in this passed array.(this itself doesn't seem good) I am wondering if their is a professional approach to dealing with this, Or am I the only one who has these "I wonder whats in the array" thoughts. One approach to tackling this could be that when we originally pass the array, in the constructor, we assign each element of the array to its own variable, but is this considered professional practice? Additionally by doing this, we could make those variables constants, in a attempt at immutability. Overall I am trying to adhere to good software craftsmanship. Regards.

• Ouya / Android : button mapping biwise

  - by scorvi

  I am programming a game with the Gameplay3d Engine. But the Android site has no gamepad support and that is what I need to port my game to Ouya. So I implemented a simple gamepad support and it supports 2 gamepads. So my problem is that I put the button stats in a float array for every gamepad. But the Gameplay3d engine saves their stats in a unsigned int _buttons variable. It is set with bitwise operations and I have no clue how to translate my array to this.

• How to name a method that both performs a task and returns a boolean as a status?

  - by Limbo Exile

  If there is a method bool DoStuff() { try { // doing stuff... return true; } catch (Exception ex) { return false; } } should it rather be called IsStuffDone()? Both names could be misinterpreted by the user: If the name is DoStuff() why does it return a boolean? If the name is IsStuffDone() it is not clear whether the method performs a task or only checks its result. Is there a convention for this case? Or an alternative approach, as this one is considered flawed? For example in languages that have output parameters, like C#, a boolean status variable could be passed to the method as one and the method's return type would be void.

• Why setter method when getter method enough in PHP OOP

  - by phphunger

  I am practicing OOP with PHP, and I am struck at setter and getter methods. I can directly access the class properties and methods with getter method then what's the use of setter method? See my example. <?php class MyClass{ public $classVar = "Its a class variable"; public function Getter(){ return $this -> classVar; } } $obj = new MyClass; echo $obj -> Getter(); ?>

• Class Versus Struct

  - by Prometheus87

  In C++ and other influenced languages there is a construct called Structure (struct) and we all know the class. Both are capable of holding functions and variables. some differences are 1. Class is given memory in heap and struct is given memory in stack 2. in class variable are private by default and in struct thy are public My question is that struct was somehow abandoned for Class. Why? other that abstraction, a struct can do all the same stuff a class does. Then why abandon it?

• Unity: Assigning String value in inspector

  - by Marc Pilgaard

  I got an issue with Unity I can't seem to comprehend, and it is possibly very simple: I am trying to write a simple piece of code in JavaScript where a button toggles the activation of a shield, by dragging a prefab with Resources.load("ActivateShieldPreFab") and destroying it again (Haven't implemented that yet). I wish to assign this button through the inspector, so I have created a string variable which appears as intended in the inspector. Though it doesn't seem to register the inspector input, even though I changed the value through the inspector. It only provides the error: "Input Key named: is unknown" When the button name is assigned within the code, there is no issues. Code as follows: var ShieldOn = false; var stringbutton : String; function Start(){ } function Update () { if(Input.GetKey(stringbutton) && ShieldOn != true) { Instantiate(Resources.load("ActivateShieldPreFab"), Vector3 (0, 0, 0), Quaternion.identity); ShieldOn = true; } } Hope somebody can help, in advance... Thanks

• Debugging-Setting Consoles in Games

  - by ShrimpCrackers

  Right now I have the graphical and input portions of a console for my game (command parsing hasn't been implemented yet). I was wondering how you would go about making changes to properties in game objects. For example, if I typed in the console: skeletonMonster maxHP 20 That would change all of the existing in-game skeletons' max hit points to 20. After you parse this information what are some ways to change the value? How can I change the variable(s) without violating information hiding? I'd like to implement this so I don't have to change variables in the code and recompile every time while playtesting.

• Optimization of time-varying parameters

  - by brama

  I need to find an optimal set of "n" parameter values that minimize an objective function (a 2-hr simulation of a system). I have looked at genetic algorithm and simulated annealing methods, but was wondering if there are any better algorithms and guidance on their merits and limitations. With the above optimization methods I can find the optimal parameter values that hold true for the entire simulation duration. Incase, I want to find the optimal "time varying" parameter values (parameter values change with time during the 2-hr simulation), are there any methods/ideas other than making each time varying parameter value a variable to optimize? Any thoughts?

• I'm having trouble understanding these exercises wording.

  - by KasHKoW

  Exercise 1-20. Write a program detab that replaces tabs in the input with the proper number of blanks to space to the next tab stop. Assume a fixed set of tab stops, say every n columns. Should n be a variable or a symbolic parameter? Exercise 1-21. Write a program entab that replaces strings of blanks by the minimum number of tabs and blanks to achieve the same spacing. Use the same tab stops as for detab. When either a tab or a single blank would suffice to reach a tab stop, which should be given preference? could you paraphrase these for me. thanks

• Is it relevant to warn about truncating real constants to 32 bits?

  - by zneak

  I'm toying around with LLVM and looking at what it would take to make yet another strongly-typed language, and now that I'm around the syntax, I've noticed that it seems to be a pet peeve of strongly typed language to warn people that their constants won't fit inside a float: // both in Java and C# float foo = 3.2; // error: implicitly truncating a double into a float // or something along these lines Why doesn't this work in Java and C#? I know it's easy to add the f after the 3.2, but is it really doing anything useful? Must I really be that aware that I'm using single-precision reals instead of double-precision reals? Maybe I'm just missing something (which, basically, is why I'm asking). Note that float foo = [const] is not the same thing as float foo = [double variable], where requiring the cast seems normal to me.

• What is a right datatype in C++ for OpenGL scene representation with use of GLSL

  - by Rarach

  I am programming in C++ OpenGl with GLSL. Until now I have been using a data structure that is composed of std::vector filled with structures of vertexes and with their parameters (position , normal, color ...) as a global variable for all the code. My question is, as I am using VBOs for drawing - is this a good approach to this problem? I am asking because I happen to have a lot of memory related trouble with this structure. I am trying to generate a terrain with a lot of vertices - more than 1 million. This seems to work, but as I refill the buffer I get memory related issues (crushes that occur, more or less randomly). So again the question is, is this a good data structure to use / and look for the faults in my code, or should I change to something else? Or what data structure would be advisable?

• Is it bad form to stage a function's steps in intermediate variables (let bindings)?

  - by octopusgrabbus

  I find I tend to need intermediate variables. In Clojure that's in the form of let bindings, like cmp-result-1 and cmp-result-2 in the following function. (defn str-cmp "Takes two strings and compares them. Returns the string if a match; and nil if not." [str-1 str-2 start-pos substr-len] (let [cmp-result-1 (subs str-1 start-pos substr-len) cmp-result-2 (subs str-2 start-pos substr-len)] (compare cmp-result-1 cmp-result-2))) I could re-write this function without them, but to me, the function's purpose looks clearer. I tend to do this quite in a bit in my main, and that is primarily for debugging purposes, so I can pass a variable to print out intermediate output. Is this bad form, and, if so, why? Thanks.

• Units in tile world

  - by Vilzow

  I've started to make a 2D sidescroller, the camera and world rendering works as I expect, but now comes the physics part of world. What I need is that one tile in x direction (or y direction) should correspond to 1 meter. Since I have a variable time step (android mobile game), I can't figure it out, since the timing and velocity always will be dependent of the device. So, is there any good way to make one tile to correspond 1 meter? This would be good, otherwise the physics implementation would later be weird.

• How to obtain window handle in SDL 2.0.3

  - by Diorthotis

  I need to obtain the handle of the window for SDL 2.0.3. I got the suggestion to use info.window after initializing SDL and filling the info variable with data by calling SDL_GetWindowWMInfo(); included in the header file SDL_syswm.h. My compiler (visual studio 2008 professional edition) gives the following error: 226) : error C2039: 'window' : is not a member of 'SDL_SysWMinfo' 1 include\sdl_syswm.h(173) : see declaration of 'SDL_SysWMinfo' Any help appreciated. Thanks. Nevermind, I needed to use "info.info.win.window". That seems a bit redundant, but whateves.
