  • How to fix weird scrolling/alignment behavior when using keyboard in MenuStrip?

    - by bentsai
    I started noticing strange behavior when navigating the main toolbar of my Winforms application, and I don't know how to fix it. When I initially open the dropdown of the File menu, it looks like this: I begin to scroll down each item with the arrow keys, and everything is fine until I reach "Exit". As soon as I hit the down arrow key from "Log Off", or if I hit the up arrow key from "Open", the menu rearranges itself to look like this: I'm puzzled by this behavior. The menu still works, and from this point, if I start scrolling up, I can get the arrangement back to normal: A few observations: The menu still works. This doesn't happen when using the mouse. I have some code that toggles the Visible property of some of the menu items. I was able to modify what the arrangement was by playing around with this, but it was still messed up. Can anyone help me understand what is going on, and how to fix it?

  • Placement/Positioning/Alignment of UIScrollView w.r.t. length of Title NSString

    - by Shoaibi
    I have a scenario where i show stuff like: ----------------------------------- titleview (UITextView) ______________ tArea (UIScrollView) ttextview (UITextView) ----------------------------------- Now here is the condition: Length of titleview's text is dynamic, varies based on user input. Because of the condition I have trouble placing tArea e.g. UIScrollView on the screen, it either appears way too below than the titleview, or overlaps it. Previously what i did: Count the number of characters in titleview.text.length and divide them by 27 (e.g. characters in one line when using boldSystemFontOfSize:20) and multiply by 10 to get the starting X of tArea e.g. UIScrollView. But that sucked. Because i had to duplicate code for rotation to landscape. What do i have now? : CGSize titlesize = [title sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 90) lineBreakMode:UILineBreakModeWordWrap]; ttitleview = [[UITextView alloc] initWithFrame:CGRectMake(5, 5, 310,titlesize.height)]; ttitleview.text = title; ttitleview.font = [UIFont boldSystemFontOfSize:20]; ttitleview.backgroundColor = [UIColor clearColor]; ttitleview.editable = NO; [self.view addSubview:ttitleview]; CGSize textsize = [ttext sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 350) lineBreakMode:UILineBreakModeWordWrap]; tArea = [[UIScrollView alloc] initWithFrame:CGRectMake(5, titlesize.height, 310, 230)]; tArea.contentSize = CGSizeMake(310, textsize.height+20); tArea.pagingEnabled = FALSE; tArea.scrollEnabled = TRUE; tArea.backgroundColor = [UIColor clearColor]; [self.view addSubview:tArea]; ttextview = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 310, textsize.height + 20)]; ttextview.text = ttext; ttextview.font = [UIFont systemFontOfSize:20]; ttextview.backgroundColor = [UIColor clearColor]; ttextview.editable = NO; [tArea addSubview:ttextview]; But its no use. Looking for an elegant solution than this.

  • How does loop address alignment affect the speed on Intel x86_64?

    - by Alexander Gololobov
    I'm seeing 15% performance degradation of the same C++ code compiled to exactly same machine instructions but located on differently aligned addresses. When my tiny main loop starts at 0x415220 it's faster then when it is at 0x415250. I'm running this on Intel Core2 Duo. I use gcc 4.4.5 on x86_64 Ubuntu. Can anybody explain the cause of slowdown and how I can force gcc to optimally align the loop?

  • I always get stuck here... Divs not behaving properly (alignment issues)

    - by user345501
    Hi, I don't know why, after encountering this problem dozens of times, the answer always seems different and I can't seem to work my way through the problem-solving process, but here I am again with misaligned divs. I've got 3rows encasing columns. each row is to have (at least) 3 columns (and probably some nested divs down the line, but I'm not even there yet). I'm trying to make a fluid chunk in the center ultimately, with pretty corners. However, my top row is already showing signs of misbehaving. .O Please help with my silly questions!

  • Properly obsoleting old members in an XML Serializable class in C# VB .NET

    - by George
    Hi! Some time ago I defined a class that was serialized using XML. That class contained a serializable propertyA of integer type. Now I have extended and updated this class, whereby a new propertyB was added, whose type is another class that also has several serializable properties. The new propertyB is now supposed to play the role of propertyA, that is since type of propertyB is another class, one of its members would contain the value that previously propertyA contained, thus making peroptyA obsolete. What I am trying to figure out is how do I make sure that when I desireliaze the OLD version of this class (without propertyB in it), I make sure that the desreializer would take the value of propertyA from the old calss and set it as a value of one of the members of propertyB in a new class? Private WithEvents _Position As Position = New Position(Alignment.MiddleMiddle, 0, True, 0, True) Public Property Position() As Position 'NEW composite property that holds the value of the obsolted property, i.e. Alignment Get Return _Position End Get Set(ByVal value As Position) _Position = value End Set End Property Private _Alignment As Alignment = Alignment.MiddleMiddle <Xml.Serialization.XmlIgnore(), Obsolete("Use Position property instead.")> _ Public Property Alignment() As Alignment'The old, obsoleted property that I guess must be left for compliance with deserializing the old version of this class Get Return _Alignment End Get Set(ByVal value As Alignment) _Alignment = value End Set End Property Can you help me, please?

  • New Regular Expression Features in Java 8

    - by Jan Goyvaerts
    Java 8 brings a few changes to Java’s regular expression syntax to make it more consistent with Perl 5.14 and later in matching horizontal and vertical whitespace. \h is a new feature. It is a shorthand character class that matches any horizontal whitespace character as defined in the Unicode standard. In Java 4 to 7 \v is a character escape that matches only the vertical tab character. In Java 8 \v is a shorthand character class that matches any vertical whitespace, including the vertical tab. When upgrading to Java 8, make sure that any regexes that use \v still do what you want. Use \x0B or \cK to match just the vertical tab in any version of Java. \R is also a new feature. It matches any line break as defined by the Unicode standard. Windows-style CRLF pairs are always matched as a whole. So \R matches \r\n while \R\R fails to match \r\n. \R is equivalent to (?\r\n|[\n\cK\f\r\u0085\u2028\u2029]) with an atomic group that prevents it from matching only the CR in a CRLF pair. Oracle’s documentation for the Pattern class omits the atomic group when explaining \R, which is incorrect. You cannot use \R inside a character class. RegexBuddy and RegexMagic have been updated to support Java 8. Java 4, 5, 6, and 7 are still supported. When you upgrade to Java 8 you can compare or convert your regular expressions between Java 8 and the Java version you were using previously.

  • Having to check collisions twice per game tic

    - by user22241
    I have vertically moving elevators (3 solid tiles wide) and static solid tiles. Each are separate entities and therefore have their own respective collision routines (to check for, and resolve, collisions with the main character) I check my vertical collisions after characters vertical movements and then horizontal collisions after horizontal movements. The problem is that I want my platform to kill the player if it squashes him from the top, and also if he's on a moving platform (that is moving up) that squashes him into a solid block. Correct behaviour, player on solid blocks being squashed from above by decending elevator Here is what happens. Gravity pushes character into solid block, solid block collision routine corrects characters position and sits him on the solid block which pushes him into the moving elevator, elevator routine then checks for collision and kills player. This assumes I am checking solid blocks first, then elevator collisions. However, if it's the other way around, this happens.... Incorrect behaviour, player on accending elevator gets pushed into solid blocks above Player is on an elevator moving up, gravity pushes him into the elevator, solid block CD routine detects no collision, no action taken. Elevator CD routine detects character has been pushed into elevator by gravity, corrects this by moving character up and sitting him on the elevator and pushes him into the solid blocks above, however the solid block vertical routine has now already run for this tic, so the game continues and the next solid block collision that is encountered is the horizontal routine. This detects a collision and moves the character out of the collision to the left or right of the block which looks odd to say the least (character should get killed here). The only way I've managed to get this working correctly is by running the solid block CD, then the elevator CD, then the solid block CD again straight after. This is clearly wasteful but I can't figure out how else to do this. Any help would be appreciated.

  • Collision Detection with SAT: False Collision for Diagonal Movement Towards Vertical Tile-Walls?

    - by Macks
    Edit: Problem solved! Big thanks to Jonathan who pointed me in the right direction. Sean describes the method I used in a different thread. Also big thanks to him! :) Here is how I solved my problem: If a collision is registered by my SAT-method, only fire the collision-event on my character if there are no neighbouring solid tiles in the direction of the returned minimum translation vector. I'm developing my first tile-based 2D-game with Javascript. To learn the basics, I decided to write my own "game engine". I have successfully implemented collision detection using the separating axis theorem, but I've run into a problem that I can't quite wrap my head around. If I press the [up] and [left] arrow-keys simultaneously, my character moves diagonally towards the upper left. If he hits a horizontal wall, he'll just keep moving in x-direction. The same goes for [up] and [left] as well as downward-diagonal movements, it works as intended: http://i.stack.imgur.com/aiZjI.png Diagonal movement works fine for horizontal walls, for both left and right-movement However: this does not work for vertical walls. Instead of keeping movement in y-direction, he'll just stop as soon as he "enters" a new tile on the y-axis. So for some reason SAT thinks my character is colliding vertically with tiles from vertical walls: http://i.stack.imgur.com/XBEKR.png My character stops because he thinks that he is colliding vertically with tiles from the wall on the right. This only occurs, when: Moving into top-right direction towards the right wall Moving into top-left direction towards the left wall Bottom-right and bottom-left movement work: the character keeps moving in y-direction as intended. Is this inherited from the way SAT works or is there a problem with my implementation? What can I do to solve my problem? Oh yeah, my character is displayed as a circle but he's actually a rectangular polygon for the collision detection. Thank you very much for your help.

  • Calc direction vector based on destination vector and distance from enemy in AS3

    - by Phil
    I'm working on a zombie game in AS3 where I want a character to be able to move away from a zombie depending upon how close the zombie is. The character also has a destination that it's trying to get too on the screen. Ok so I have 2 vectors, one pointing to my destination, and one pointing to the zombie which I then invert to get my "away" vector. I then turn the distance between my character and the zombie into a value between 0 and 1. And then I'm stuck on how to get a resultant vector for my character. How would I use my 0-1 value to calculate how much of the away vector is used and how much of the original destination vector is still left if that makes sense? to end up with 1 direction vector to move my character? So if the zombie is right where my character is, then my direction vector = away vector, and if I'm far away from the zombie than my direction vector = destination vector, but how do I calculate the in-between? Ideally need the answer in AS3.

  • Preventing item duplication?

    - by PuppyKevin
    For my game, there's two types of items - stackable, and nonstackable. Nonstackable items get assigned a unique ID that stays with it forever. A character ID is assosicated with the item, as is a state (CHANGED, UNCHANGED, NEW, REMOVED). The character ID and state is used for item saving purposes. Stackable items have one unique ID, as in the entire stack has one unique ID. For example: 5 Potions (stacked ontop of each other) has one unique ID. When dropping a nonstackable item, the state gets set to REMOVED, and the unique ID and state don't change. If picked up by another player, the state gets set to NEW, and the character ID gets changed to the new character's ID. When dropping all items in a stack of stackable items (for example, 5 potions out of 5) - it behaves just like a nonstackable item. When dropping some of a stack of stackable items (for example, 3 potions out of 5)... I really have no clue what to do. The 3 dropped potions have the state of REMOVED, but the same unique ID and character ID. If another player picks it up, it has no choice but to obtain a new unique ID, and its state gets changed to NEW and its character ID to the new one. If the dropping player picks it back up, they'd just be readded to the stack. There's two issues with that though. 1. If the player who dropped the 3 potions picks it back up, there's no way to tell if they legitimately dropped the items, or if they're duped items. 2. If another player picks up the 3 potions (assuming they're duped), there's no way to know if they're duped or not. My question is: How can I create a system that detects duplicated items for both nonstackable and stackable items?

  • How can I pass an external instance to the constructor of an object that's being created using the default XNA XML content loader?

    - by Michael
    I'm trying to understand how to use the XNA XML content importer to instantiate non-trivial objects that are more than a collection of basic properties (e.g., a class that inherits from DrawableGameObject or GameObject and requires other things to be passed into its constructor). Is it possible to pass existing external instances (e.g., an instance of the current Game) to the constructor of an object that's being created using the default XNA XML content loader? For example, imagine that I have the following class, inheriting from DrawableGameComponent: public class Character : DrawableGameComponent { public string Name { get; set; } public Character(Game game) : base(game) { } public override void Update(GameTime gameTime) { } public override void Draw(GameTime gameTime) { } } If I had a simple class that did not need other parameters in its constructor (i.e., the Game instance), then I could simply use this XML: <XnaContent> <Asset Type="MyNamespace.Character"> <Name>John Doe</Name> </Asset> </XnaContent> ...and then create an instance of Character using this code: var character = Content.Load<Character>("MyXmlAssetName"); But that won't work because I need to pass the need to pass the Game into the constructor. What's the best way to handle this situation? Is there a way to pass in things like the current Game using the default XNA XML content loader? Do I need to write my own XML loader? (If so, how?) Is there a better object-oriented design that I should be using for my classes? Note: Although I used Game in this example, I'm really just asking how to pass any type of existing instance to my constructors. (For example, I'm using the Farseer Physics Engine, and some of my classes also need a reference to the Farseer World object too.) Thanks in advance.

  • Moving characters on a grid [on hold]

    - by madmax1
    i am developing my first game with C++. My game uses a grid of rectangles. I have a class Board which manages the grid as a whole, initializes the terrain, places/removes characters, etc. It has a 2D vector of a class Field, which handles the Structure of the field, contained Objects, Characters, etc. Field again contains a vector of class Character, which are positioned on the field. Now i want to implement the functionality to move a character on the board, however dont know which is best practice to do so. Should i implement a moveCharacter(character, offset) function in Board, make it search for the character and move it? Or should i implement a function move(offset) in Character? This sure would be nicest, however makes characters necessary to know the board they are on, or the field which in turn knows the board. On the one hand i feel like i should avoid inclusion between classes as much as possible e.g. to increase portability of classes for different projects, on the other hand i think the character.move() functionality is most comfortable for further development. Im pretty new to "bigger" C++ projects and these kind of design questions pop up more and more often lately and i have troubles deciding. Thanks a lot for any advice!

  • How do you handle animations that are for transitioning between states?

    - by yaj786
    How does one usually handle animations that are for going between a game object's states? For example, imagine a very simple game in which a character can only crouch or stand normally. Currently, I use a custom Animation class like this: class Animation{ int numFrames; int curFrame; Bitmap spriteSheet; //... various functions for pausing, returning frame, etc. } and an example Character class class Character{ int state; Animation standAni; Animation crouchAni; //... etc, etc. } Thus, I use the state of the character to draw the necessary animation. if(state == STATE_STAND) draw(standAni.updateFrame()); else if(state == STATE_CROUCH) draw(crouchAni.updateFrame()); Now I've come to the point where I want to draw "in-between" animations, because right now the character will just jump immediately into a crouch instead of bending down. What is a good way to handle this? And if the way that I handle storing Animations in the Character class is not a good way, what is? I thought of creating states like STATE_STANDING_TO_CROUCHING but I feel like that may get messy fast.

  • Make Gameobject Stand On Surface Facing Certain Direction

    - by Julian
    I want to make a biped character stand on any surface I click on. Surfaces have up vectors of any of positive or negative X,Y,Z. So imagine a cube with each face being a gameobject whose up vector pointing directly away from the cube. If my character is facing "forward" and I click on a surface which is to the left or right of me ( left or right walls), I want my character to now be standing on that surface but still be facing in the direction he initially was. If I click on a wall which is in the forward path of my character i want him to now be standing on that surface and his forward to now be what was once "up" relative to my character. Here is the code I am working with now. void Update() { if (Input.GetMouseButtonUp (0)) { RaycastHit hit; var ray = Camera.main.ScreenPointToRay(Input.mousePosition); if (Physics.Raycast(ray, out hit)) { Vector3 upVectBefore = transform.up; Vector3 forwardVectBefore = transform.forward; Quaternion rotationVectBefore = transform.rotation; Vector3 hitPosition = hit.transform.position; transform.position = hitPosition; float lookDifference = Vector3.Distance(hit.transform.up, forwardVectBefore); if(Vector3.Distance(hit.transform.up, upVectBefore) < .23) //Same normal { transform.rotation = rotationVectBefore; } else if(lookDifference > 1.412 && lookDifference <= 1.70607) //side wall { transform.up = hit.transform.up; transform.forward = forwardVectBefore; } else //head on wall { transform.up = hit.transform.up; transform.forward = upVectBefore; } } } } The first case "Same normal" works fine, however the other two do not work as I would like them to. Sometimes my character is laying down on the surface or on the wrong side of the surface. Does anyone know nice way of solving this problem?

  • F5 Networks iRule/Tcl - Escaping UNICODE 6-character escape sequences so they are processed as and r

    - by openid.malcolmgin.com
    We are trying to get an F5 BIG-IP LTM iRule working properly with SharePoint 2007 in an SSL termination role. This architecture offloads all of the SSL processing to the F5 and the F5 forwards interactive requests/responses to the SharePoint front end servers via HTTP only (over a secure network). For the purposes of this discussion, iRules are parsed by a Tcl interpretation engine on the F5 Networks BIG-IP device. As such, the F5 does two things to traffic passing through it: Redirects any request to port 80 (HTTP) to port 443 (HTTPS) through HTTP 302 redirects and URL rewriting. Rewrites any response to the browser to selectively rewrite URLs embedded within the HTML so that they go to port 443 (HTTPS). This prevents the 302 redirects from breaking DHTML generated by SharePoint. We've got part 1 working fine. The main problem with part 2 is that in the response rewrite because of XML namespaces and other similar issues, not ALL matches for "http:" can be changed to "https:". Some have to remain "http:". Additionally, some of the "http:" URLs are difficult in that they live in SharePoint-generated JavaScript and their slashes (i.e. "/") are actually represented in the HTML by the UNICODE 6-character string, "\u002f". For example, in the case of these tricky ones, the literal string in the outgoing HTML is: http:\u002f\u002fservername.company.com\u002f And should be changed to: https:\u002f\u002fservername.company.com\u002f Currently we can't even figure out how to get a match in a search/replace expression on these UNICODE sequence string literals. It seems that no matter how we slice it, the Tcl interpreter is interpreting the "\u002f" string into the "/" translation before it does anything else. We've tried various combinations of Tcl escaping methods we know about (mainly double-quotes and using an extra "\" to escape the "\" in the UNICODE string) but are looking for more methods, preferably ones that work. Does anyone have any ideas or any pointers to where we can effectively self-educate about this? Thanks very much in advance.

  • How to change mod_rewrite to avoid {REQUEST_FILENAME} in order to get around 255 character URL limit?

    - by Jeremy Reimer
    According to this answer: max length of url 257 characters for mod_rewrite? there is a maximum 255 character hard limit based on the file system for using mod_rewrite. According to the accepted answer, there are two solutions: Change the URL format of your application to a max of 255 characters between each slash. Move the Rewrite rules into the apache virtual host config and remove the REQUEST_FILENAME. I cannot use the first method, so I am trying to figure out the second. I have put the Rewrite rules into the Apache virtual host config as requested. However I cannot figure out how to remove the REQUEST_FILENAME and still have my web application framework (Dragonfly) still work. Here is the portion of the rewrite rules that I moved from .htaccess into the virtual host config file of Apache: RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-l RewriteCond %{REQUEST_FILENAME} !-f [OR] # if don't want Dragonfly to process html files comment # out the line below (you may need to remove the [OR] above too). RewriteCond %{REQUEST_FILENAME} \.(html|nl)$ # Main URL rewriting. RewriteRule (.*) index.cgi?$1 [L,QSA] I've tried removing {REQUEST_FILENAME} and it just breaks the framework in various ways. How do I rewrite this without using {REQUEST_FILENAME}?

  • Why is my program printing out the null termination character?

    - by Tyler Pfaff
    When I run this, it will SOMETIMES print out a null termination character. Most of the time it will, and probably 1/5 times it will print just the characters. void cryptogram::Encrypt(){ cout<<"encrypt"<tempS){ len=tempS.length(); int a=0; for(int j=0;j if(j!=len){ //if the word still has more characters j++; a=0; }else{ //if the word is done being scanned cout<<" "; } } } } } } } So that's it and this is the corresponding EXPECTED output that is printed SOMETIMES xvk bkikhxlr wggbtfkj wiylekgbdhx wjjm hko wigbtubxt xvk iwhj uedjkm glctb gvrmdiwhj iebbdielmeggtbx ctb xvtmk gbtubxvk wjjdxdthgbtubodll khvxvk imkbfdik xt xvk bkudth whj gbtfdjk hko tgxdthm whj tggtbxehdxdkm ctb mxejkhxmibdzdhtltur whj pemxdik mxejdkm mxdh cok wbk wlmt gbkgctb cteb hko zdh cgvrmdikjeiwhj qdhkmdtlturzzkjdydtivkzdmxbrw zdh zdjjlkkjeiwhj w jtixtbdh kjeiwjzdhdmxbittgkbodxv mjme whj eimj This is what normally prints though xvkÈ bkikhxlrÈ wggbtfkjÈ wiylekgbdhxÈ wjjmÈ hkoÈ wigbtubxtÈ xvkÈ iwhjÈ uedjkmÈ glctbÈ gvrmdiwhjÈ iebbdielmeggtbxÈ ctbÈ xvtmkÈ gbtubxvkÈ wjjdxdthgbtubodllÈ khvxvkÈ imkbfdikÈ xtÈ xvkÈ bkudthÈ whjÈ gbtfdjkÈ hkoÈ tgxdthmÈ whjÈ tggtbxehdxdkmÈ ctbÈ mxejkhxmibdzdhtlturÈ whjÈ pemxdikÈ mxejdkmÈ mxdhÈ cokÈ wbkÈ wlmtÈ gbkgctbÈ ctebÈ hkoÈ zdhÈ cgvrmdikjeiwhjÈ qdhkmdtlturzzkjdydtivkzdmxbrwÈ zdhÈ zdjjlkkjeiwhjÈ wÈ jtixtbdhÈ kjeiwjzdhdmxbittgkbodxvÈ mjmeÈ whjÈ eimj or some variation of an odd character at the end of each word This is what the cryptogram array is filled with by the way wyijkcuvdpqlzhtgabmxefonrs

  • Why can't I display a unicode character in the Python Interpreter on Mac OS X Terminal.app?

    - by apphacker
    If I try to paste a unicode character such as the middle dot: · in my python interpreter it does nothing. I'm using Terminal.app on Mac OS X and when I'm simply in in bash I have no trouble: :~$ · But in the interpreter: :~$ python Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> ^^ I get nothing, it just ignores that I just pasted the character. If I use the escape \xNN\xNN representation of the middle dot '\xc2\xb7', and try to convert to unicode, trying to show the dot causes the interpreter to throw an error: >>> unicode('\xc2\xb7') Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 0: ordinal not in range(128) I have setup 'utf-8' as my default encoding in sitecustomize.py so: >>> sys.getdefaultencoding() 'utf-8' What gives? It's not the Terminal. It's not Python, what am I doing wrong?! This question is not related to this question, as that indivdiual is able to paste unicode into his Terminal.
