  • SFML fail to load image as texture

    - by zyeek
    I have come to a problem with the code below ... Using SFML 2.0 #include <SFML/Graphics.hpp> #include <iostream> #include <list> int main() { float speed = 5.0f; // create the window sf::RenderWindow window(sf::VideoMode(sf::VideoMode::getDesktopMode().height - 300, 800), "Bricks"); // Set game window position on the screen window.setPosition( sf::Vector2i(sf::VideoMode::getDesktopMode().width/4 + sf::VideoMode::getDesktopMode().width/16 , 0) ); // Allow library to accept repeatitive key presses (i.e. holding key) window.setKeyRepeatEnabled(true); // Hide mouse cursor //window.setMouseCursorVisible(false); // Limit 30 frames per sec; the minimum for all games window.setFramerateLimit(30); sf::Texture texture; if (!texture.loadFromFile("tile.png", sf::IntRect(0, 0, 125, 32))) { std::cout<<"Could not load image\n"; return -1; } // Empty list of sprites std::list<sf::Sprite> spriteContainer; bool gameFocus = true; // run the program as long as the window is open while (window.isOpen()) { sf::Vector2i mousePos = sf::Mouse::getPosition(window); // check all the window's events that were triggered since the last iteration of the loop sf::Event event; while (window.pollEvent(event)) { float offsetX = 0.0f, offsetY = 0.0f; if(event.type == sf::Event::GainedFocus) gameFocus = !gameFocus; else if(event.type == sf::Event::LostFocus) gameFocus = !gameFocus; if(event.type == sf::Event::KeyPressed) { if (event.key.code == sf::Keyboard::Space) { if(gameFocus) { // Create sprite and add features before putting it into container sf::Sprite sprite(texture); sprite.scale(.9f,.7f); sf::Vector2u textSize = texture.getSize(); sprite.setPosition(sf::Vector2f(mousePos.x-textSize.x/2.0f, mousePos.y - textSize.y/2.0f)); spriteContainer.push_front(sprite); } } if(event.key.code == sf::Keyboard::P) std::cout << spriteContainer.size() << std::endl; if( event.key.code == sf::Keyboard::W ) offsetY -= speed; if( event.key.code == sf::Keyboard::A ) offsetX -= speed; if( event.key.code == sf::Keyboard::S ) offsetY += speed; if( event.key.code == sf::Keyboard::D ) offsetX += speed; } // "close requested" event: we close the window if (event.type == sf::Event::Closed || event.key.code == sf::Keyboard::Escape) window.close(); // Move all sprites synchronously for (std::list<sf::Sprite>::iterator sprite = spriteContainer.begin(); sprite != spriteContainer.end(); ++sprite) sprite->move(offsetX, offsetY); //sprite.move(offsetX,offsetY); } // clear the window with black color window.clear(sf::Color::Black); // draw everything here... // window.draw(...); // Draw all sprites in the container for (std::list<sf::Sprite>::iterator sprite = spriteContainer.begin(); sprite != spriteContainer.end(); ++sprite) window.draw(*sprite); // end the current frame window.display(); } return 0; } A couple weeks ago it worked flawlessly to my expectation, but now that I come back to it and I am having problems importing the image as a texture "tile.png". I don't understand why this is evening happening and the only message I get via the terminal is "Cannot load image ..." then a bunch of random characters. My libraries are for sure working, but now I am not sure why the image is not loading. My image is in the same directory as with my .h and .cpp files. This is an irritating problem that keep coming up for some reason and is always a problem to fix it. I import my libraries via my own directory "locals" which contain many APIs, but I specifically get SFML, and done appropriately as I am able to open a window and many other stuff.

  • Url rewrite subfolder to root and forbid accessing subfolder

    - by Alessandro Pezzato
    I have drupal installed in a subfolder drupal, but I want to access pages as it is in root folder: http://www.example.com instead of http://www.example.com/drupal I'm able to have this working, but it's also working with url containing subfolder, so I have http://www.example.com and a clone site in http://www.example.com/drupal What is the rule to forbid access to subfolder?

  • SQL SERVER – Performance Tuning Resolution

    - by pinaldave
    This blog post is written in response to T-SQL Tuesday hosted by MidnightDBAs. Taking resolutions is such an interesting subject. I think just like records, these are broken way more often. I find this is the funniest thing as we all take resolutions every year but not every year, we can manage to keep them. Well, does it mean we should not take resolutions? In fact I support resolutions. Every year, I take a resolution that I will strive reduce my body weight and I usually manage to keep eating healthy till the end of January. When February begins, I begin to loose focus from my goal and as March starts, the “As usual” eating habits begin. Looking at the positive side, what would happen if every year I do not eat healthy in January, I think that might cause terrible consequences to my health in the long run. So keeping resolutions is a good practise and following them to the extent one can is commendable. Let us come back to the world of SQL Server. What is my resolution for year 2011 for SQL Server? There are many, I am going to list three of very important resolutions that I have taken this new year over here. To understand SQL Server Performance Tuning at a deeper Level I think I am already half way through. I have been being very much busy during any given month doing hands-on performance tuning for at least 12 days on an average. That means, I am doing this activity for almost doing 2 weeks a month. I believe that I have a good understanding of the subject. Note that the word that I have used is “good,” and not “best.” There are often cases when I am stumped, and I have no clue of what to do next. Then, I usually go for my “trial and error” method - whichever method works, I make sure to keep a note on my blog. My goal is that I should never ever go for the trial and error method again to achieve the same solution. I should know the solution right away when I see the problem. I do understand that Performance Tuning can be a strange animal at times and one cannot guess the right step every time. However, aiming a high goal never hurts and I am going to learn more and more in this focused area. Going further from Basic BI understanding I do fairly decent with BI concepts. I know the nbasics of SSIS, SSRS, SSAS, PowerPivot and SharePoint (and few other things MDS, StreamInsight, etc). However, I still consider myself as a beginner. I do not have hands-on experience like many other BI Gurus around. I think I want to take my learning further in this direction. I do not want to be a BI expert as the first step but the goal is to move ahead from basic level towards an advanced level. I am going to start presenting in User Group Sessions and other places on this subject. When I have to prepare new subject for presentations, I think I force myself to learn more. I am committed to learn a bit more in this direction. Learning new features SQL Server 2011 Denali This is new thing from “Microsoft” for all the SQL Geeks. I am eagerly waiting for final product later this year and I am planning to learn it well. I think if I follow my above two goals, I think this goal will be automatically covered. I am eager and excited for this new offering from Microsoft. I guess, these are my resolutions; may be next year about the same time, I must revisit this post and see how much successful I am in following my goal. On a lighter note, I am particularly fan of following cartoon strip (Courtesy: Calvin and Hobbes). I think when we cannot resolve our resolutions, we tend to act like Calvin.

  • Heading out to Dallas GiveCamp 2011

    - by dotgeek
    The day has finally arrived for twelve local charities here in the Dallas area, when they’ll get some help from various local Developers with their website initiative needs at this years Dallas GiveCamp. I’m really looking forward to helping out at this year event and what I hope will be the start of many more GiveCamps to follow. Similar to Habitat for Humanity, where people gather to help build and improve homes for people in need, GiveCamp brings together programmers and equips them with the virtual tools they need to build and improve their existing websites. Tonight is when things will kickoff for this weekends events and teams will start working on their various projects. The building continues on through the night then and all the way through until Sunday afternoon. The end goal for the teams and charities is to have a completed and working website for each charity to begin using and turn over all the production code and digital assets to them. None of this would be possible with out the great sponsors we have returning once again and their donations of various products to help these charities out with their projects, like Telerik's CMS product Sitefinity 4.0, paired with a year of hosting from Verio to mention just a few of them. Just like the skilled builders who might help train volunteers in the use of a nail gun in building a house. Training is also available here on site for the Developers and these local Charities. Giving them all the skills in how to manage and use these products, from site development and then into actual production is a key to the success of this weekends event.     Tonight's training sessions will kick off with a real treat from Giovanni Gallucci, as he speaks about Social Media for NPOs and then later Gabe Sumner from Telerik will begin a training session on Sitefinity for Developers. These training sessions will continue through out the weekend with .Net Nuke and Mojo Portal sessions also planned as well. If you’re a developer and would like to help out in the future, then check in your area and with your local User Groups to find out if you already have a GiveCamp near you to help out. If you don’t have one available, then consider starting up a local GiveCamp and then you too can help Code it Forward. About GiveCamp GiveCamp is a weekend-long event where software developers, designers, and database administrators donate their time to create custom software for non-profit organizations. This custom software could be a new website for the nonprofit organization, a small data-collection application to keep track of members, or a application for the Red Cross that automatically emails a blood donor three months after they’ve donated blood to remind them that they are now eligible to donate again. The only limitation is that the project should be scoped to be able to be completed in a weekend. During GiveCamp, developers are welcome to go home in the evenings or camp out all weekend long. There are usually food and drink provided at the event. There are sometimes even game systems set up for when you and your need a little break! Overall, it’s a great opportunity for people to work together, developing new friendships, and doing something important for their community. At GiveCamp, there is an expectation of “What Happens at GiveCamp, Stays at GiveCamp”. Therefore, all source code must be turned over to the charities at the end of the weekend (developers cannot ask for payment) and the charities are responsible for maintaining the code moving forward (charities cannot expect the developers to maintain the codebase).

  • LibGdx drawing weird behaviour

    - by Ryckes
    I am finding strange behaviour while rendering TextureRegions in my game, only when pausing it. I am making a game for Android, in Java with LibGdx. When I comment out the line "drawLevelPaused()" everything seems to work fine, both running and paused. When it's not commented, everything works fine until I pause the screen, then it draws those two rectangles, but maybe ships are not shown, and if I comment out drawShips() and drawTarget() (just trying) maybe one of the planets disappears, or if I change the order, other things disappear and those that disappeared before now are rendered again. I can't find the way to fix this behaviour I beg your help, and I hope it's my mistake and not a LibGdx issue. I use OpenGL ES 2.0, stated in AndroidManifest.xml, if it is of any help. Thank you in advance. My Screen render method(game loop) is as follows: @Override public void render(float delta) { Gdx.gl.glClearColor(0.1f, 0.1f, 0.1f, 1); Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); controller.update(delta); renderer.render(); } When world state is PAUSED controller.update does nothing at all, there is a switch in it. And renderer.render() is as follows: public void render() { int worldState=this.world.getWorldState(); updateCamera(); spriteBatch.begin(); drawPlanets(); drawTarget(); drawShips(); if(worldState==World.PAUSED) { drawLevelPaused(); } else if(worldState==World.LEVEL_WON) { drawLevelWin(); } spriteBatch.end(); } And those methods are: private void updateCamera() { this.offset=world.getCameraOffset(); } private void drawPlanets() { for(Planet planet : this.world.getPlanets()) { this.spriteBatch.draw(this.textures.getTexture(planet.getTexture()), (planet.getPosition().x - this.offset[0]) * ppuX, (planet.getPosition().y - this.offset[1]) * ppuY); } } private void drawTarget() { Target target=this.world.getTarget(); this.spriteBatch.draw(this.textures.getTexture(target.getTexture()), (target.getPosition().x - this.offset[0]) * ppuX, (target.getPosition().y - this.offset[1]) * ppuY); } private void drawShips() { for(Ship ship : this.world.getShips()) { this.spriteBatch.draw(this.textures.getTexture(ship.getTexture()), (ship.getPosition().x - this.offset[0]) * ppuX, (ship.getPosition().y - this.offset[1]) * ppuY, ship.getBounds().width*ppuX/2, ship.getBounds().height*ppuY/2, ship.getBounds().width*ppuX, ship.getBounds().height*ppuY, 1.0f, 1.0f, ship.getAngle()-90.0f); } if(this.world.getStillShipVisibility()) { Ship ship=this.world.getStillShip(); Arrow arrow=this.world.getArrow(); this.spriteBatch.draw(this.textures.getTexture(ship.getTexture()), (ship.getPosition().x - this.offset[0]) * ppuX, (ship.getPosition().y - this.offset[1]) * ppuY, ship.getBounds().width*ppuX/2, ship.getBounds().height*ppuY/2, ship.getBounds().width*ppuX, ship.getBounds().height*ppuY, 1f, 1f, ship.getAngle() - 90f); this.spriteBatch.draw(this.textures.getTexture(arrow.getTexture()), (ship.getCenter().x - this.offset[0] - arrow.getBounds().width/2) * ppuX, (ship.getCenter().y - this.offset[1]) * ppuY, arrow.getBounds().width*ppuX/2, 0, arrow.getBounds().width*ppuX, arrow.getBounds().height*ppuY, 1f, arrow.getRate(), ship.getAngle() - 90f); } } private void drawLevelPaused() { this.shapeRenderer.begin(ShapeType.FilledRectangle); this.shapeRenderer.setColor(0f, 0f, 0f, 0.8f); this.shapeRenderer.filledRect(0, 0, this.width/this.ppuX, PAUSE_MARGIN_HEIGHT/this.ppuY); this.shapeRenderer.filledRect(0, (this.height-PAUSE_MARGIN_HEIGHT)/this.ppuY, this.width/this.ppuX, PAUSE_MARGIN_HEIGHT/this.ppuY); this.shapeRenderer.end(); for(Button button : this.world.getPauseButtons()) { this.spriteBatch.draw(this.textures.getTexture(button.getTexture()), (button.getPosition().x - this.offset[0]) * this.ppuX, (button.getPosition().y - this.offset[1]) * this.ppuY); } }

  • RewriteRule not working for certain URLs

    - by keiki
    There are a few domains pointing towards the same server, and of course I need them all redirect to only one of them. Redirects work, but only for certain URLs. What works: http://www.domain.com, http://domain.com, domain.com/index.html, domain.com/index.php, , domain.com/nonExistentDirectory, and if I click in the menu the following URLs are also redirected correctly: domain.com/foo/bar, domain.com/foo/bar.html or .php or other extension. What doesn't work: domain.com/existentDirectory, domain.com/foo/bar (if I type the URL in the address bar). If anyone will have the time and skill and will to tell me where's the mistake, I'll be deeply grateful. Here's my .htaccess file: AddHandler x-httpd-php .html .htm <ifModule mod_gzip.c> mod_gzip_on Yes mod_gzip_dechunk Yes mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$ mod_gzip_item_include handler ^cgi-script$ mod_gzip_item_include mime ^text/.* mod_gzip_item_include mime ^application/x-javascript.* mod_gzip_item_exclude mime ^image/.* mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.* </ifModule> <ifModule mod_expires.c> ExpiresActive On ExpiresDefault "access plus 1 seconds" ExpiresByType text/html "access plus 1 seconds" ExpiresByType image/gif "access plus 2592000 seconds" ExpiresByType image/jpeg "access plus 2592000 seconds" ExpiresByType image/png "access plus 2592000 seconds" ExpiresByType text/css "access plus 2592000 seconds" ExpiresByType text/javascript "access plus 216000 seconds" ExpiresByType application/x-javascript "access plus 216000 seconds" </ifModule> <ifModule mod_headers.c> <filesMatch "\\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$"> Header set Cache-Control "max-age=2592000, public" </filesMatch> <filesMatch "\\.(css)$"> Header set Cache-Control "max-age=2592000, public" </filesMatch> <filesMatch "\\.(js)$"> Header set Cache-Control "max-age=216000, private" </filesMatch> <filesMatch "\\.(xml|txt)$"> Header set Cache-Control "max-age=216000, public, must-revalidate" </filesMatch> <filesMatch "\\.(html|htm|php)$"> Header set Cache-Control "max-age=1, private, must-revalidate" </filesMatch> </ifModule> <ifModule mod_headers.c> Header unset ETag </ifModule> FileETag None <ifModule mod_headers.c> Header unset Last-Modified </ifModule> # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress RewriteCond %{HTTP_HOST} ^foo\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.foo\.com$ RewriteRule (.*) http://domain.com/$1 [R=301,L,QSA] RewriteCond %{HTTP_HOST} ^foo1\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.foo1\.com$ RewriteRule (.*) http://domain.com/$1 [R=301,L,QSA] RewriteCond %{HTTP_HOST} ^foo2\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.foo2\.com$ RewriteRule (.*) http://domain.com/$1 [R=301,L,QSA] RewriteCond %{HTTP_HOST} ^foo3\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.foo3\.com$ RewriteRule (.*) http://domain.com/$1 [R=301,L,QSA] RewriteCond %{HTTP_HOST} ^foo8\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.foo8\.com$ RewriteRule (.*) http://domain.com/$1 [R=301,L,QSA] Thinking that the above version was overkill, I've also tried to redirect all the requests for domains different than the main on to be redirected to it like this: RewriteCond %{HTTP_HOST} !^domain\.com$ [NC] RewriteRule ^(.*)$ http://domain.com [L,R=301] Is it also wrong? Because it doesn't work either! P.S. @Sodved I've tried that and it doesn't help (I comment here because I can't seem to be able to comment your answer.) Removing the following piece of code didn't solve the issue either, so the problem must be somewhere else: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress New details: using this tool for checking the redirects I got the following results for the URLs that are not redirected: Checked link: http://domain.com/aDirectory/ Type of link: direct link (note the trailing slash above) and: Checked link: http://domain.com/aDirectory Type of redirect: 301 Moved Permanently Redirected to: http://domain.com/aDirectory/ (no trailing slash here) I hope/suspect I'm getting closer to the cause of this behavior.

  • Improving the efficiency of frustum culling

    - by DeadMG
    I've got some code which performs frustum culling. However, this defines the "frustum" way too broadly- when I have ~10 objects on screen, the code returns 42 objects to be rendered. I've tried taking "slices" through the frustum to attempt to increase the accuracy of the technique, but it doesn't seem to have made much impact. I also significantly reduced the far plane, so that the objects are barely at the edge. Here's my code (where size is the size in screen space- the resolution of the client area of the window I'm rendering into). Any suggestions? auto&& size = GetDimensions(); D3DVIEWPORT9 vp = { 0, 0, size.x, size.y, 0, 1 }; D3DCALL(device->SetViewport(&vp)); static const int slices = 10; std::vector<Object*> result; for(int i = 0; i < slices; i++) { D3DXVECTOR3 WorldSpaceFrustrumPoints[8] = { D3DXVECTOR3(0, size.y, static_cast<float>(i) / slices), D3DXVECTOR3(size.x, 0, static_cast<float>(i) / slices), D3DXVECTOR3(size.x, size.y, static_cast<float>(i) / slices), D3DXVECTOR3(0, 0, static_cast<float>(i) / slices), D3DXVECTOR3(0, 0, static_cast<float>(i + 1) / slices), D3DXVECTOR3(size.x, 0, static_cast<float>(i + 1) / slices), D3DXVECTOR3(size.x, size.y, static_cast<float>(i + 1) / slices), D3DXVECTOR3(0, size.y, static_cast<float>(i + 1) / slices) }; D3DXMATRIXA16 Identity; D3DXMatrixIdentity(&Identity); D3DXVec3UnprojectArray( WorldSpaceFrustrumPoints, sizeof(D3DXVECTOR3), WorldSpaceFrustrumPoints, sizeof(D3DXVECTOR3), &vp, &Projection, &View, &Identity, 8 ); Math::AABB Frustrum; auto world_begin = std::begin(WorldSpaceFrustrumPoints); auto world_end = std::end(WorldSpaceFrustrumPoints); auto world_initial = WorldSpaceFrustrumPoints[0]; Frustrum.BottomLeftClosest.x = std::accumulate(world_begin, world_end, world_initial, [](D3DXVECTOR3 lhs, D3DXVECTOR3 rhs) { return lhs.x < rhs.x ? lhs : rhs; }).x; Frustrum.BottomLeftClosest.y = std::accumulate(world_begin, world_end, world_initial, [](D3DXVECTOR3 lhs, D3DXVECTOR3 rhs) { return lhs.y < rhs.y ? lhs : rhs; }).y; Frustrum.BottomLeftClosest.z = std::accumulate(world_begin, world_end, world_initial, [](D3DXVECTOR3 lhs, D3DXVECTOR3 rhs) { return lhs.z < rhs.z ? lhs : rhs; }).z; Frustrum.TopRightFurthest.x = std::accumulate(world_begin, world_end, world_initial, [](D3DXVECTOR3 lhs, D3DXVECTOR3 rhs) { return lhs.x > rhs.x ? lhs : rhs; }).x; Frustrum.TopRightFurthest.y = std::accumulate(world_begin, world_end, world_initial, [](D3DXVECTOR3 lhs, D3DXVECTOR3 rhs) { return lhs.y > rhs.y ? lhs : rhs; }).y; Frustrum.TopRightFurthest.z = std::accumulate(world_begin, world_end, world_initial, [](D3DXVECTOR3 lhs, D3DXVECTOR3 rhs) { return lhs.z > rhs.z ? lhs : rhs; }).z; auto slices_result = ObjectTree.collision(Frustrum); result.insert(result.end(), slices_result.begin(), slices_result.end()); } return result;

  • At what point does "constructive" criticism of your code become unhelpful?

    - by user15859
    I recently started as a junior developer. As well as being one of the least experienced people on the team, I'm also a woman, which comes with all sorts of its own challenges working in a male-dominated environment. I've been having problems lately because I feel like I am getting too much unwarranted pedantic criticism on my work. Let me give you an example of what happened recently. Team lead was too busy to push in some branches I made, so he didn't get to them until the weekend. I checked my mail, not really meaning to do any work, and found that my two branches had been rejected on the basis of variable names, making error messages more descriptive, and moving some values to the config file. I don't feel that rejecting my branch on this basis is useful. Lots of people were working over the weekend, and I had never said that I would be working. Effectively, some people were probably blocked because I didn't have time to make the changes and resubmit. We are working on a project that is very time-sensitive, and it seems to me that it's not helpful to outright reject code based on things that are transparent to the client. I may be wrong, but it seems like these kinds of things should be handled in patch type commits when I have time. Now, I can see that in some environments, this would be the norm. However, the criticism doesn't seem equally distributed, which is what leads to my next problem. The basis of most of these problems was due to the fact that I was in a codebase that someone else had written and was trying to be minimally invasive. I was mimicking the variable names used elsewhere in the file. When I stated this, I was bluntly told, "Don't mimic others, just do what's right." This is perhaps the least useful thing I could have been told. If the code that is already checked in is unacceptable, how am I supposed to tell what is right and what is wrong? If the basis of the confusion was coming from the underlying code, I don't think it's my responsibility to spend hours refactoring a whole file that someone else wrote (and works perfectly well), potentially introducing new bugs etc. I'm feeling really singled out and frustrated in this situation. I've gotten a lot better about following the standards that are expected, and I feel frustrated that, for example, when I refactor a piece of code to ADD error checking that was previously missing, I'm only told that I didn't make the errors verbose enough (and the branch was rejected on this basis). What if I had never added it to begin with? How did it get into the code to begin with if it was so wrong? This is why I feel so singled out: I constantly run into this existing problematic code, that I either mimic or refactor. When I mimic it, it's "wrong", and if I refactor it, I'm chided for not doing enough (and if I go all the way, introducing bugs, etc). Again, if this is such a problem, I don't understand how any code gets into the codebase, and why it becomes my responsibility when it was written by someone else, who apparently didn't have their code reviewed. Anyway, how do I deal with this? Please remember that I said at the top that I'm a woman, and I'm sure these guys don't usually have to worry about decorum when they're reviewing other guys' code, but honestly that doesn't work for me, and it's causing me to be less productive. I'm worried that if I talk to my manager about it, he'll think I can't handled the environment, etc.

  • With a little effort you can &ldquo;SEMI&rdquo;-protect your C# assemblies with obfuscation.

    - by mbcrump
    This method will not protect your assemblies from a experienced hacker. Everyday we see new keygens, cracks, serials being released that contain ways around copy protection from small companies. This is a simple process that will make a lot of hackers quit because so many others use nothing. If you were a thief would you pick the house that has security signs and an alarm or one that has nothing? To so begin: Obfuscation is the concealment of meaning in communication, making it confusing and harder to interpret. Lets begin by looking at the cartoon below:     You are probably familiar with the term and probably ignored this like most programmers ignore user security. Today, I’m going to show you reflection and a way to obfuscate it. Please understand that I am aware of ways around this, but I believe some security is better than no security.  In this sample program below, the code appears exactly as it does in Visual Studio. When the program runs, you get either a true or false in a console window. Sample Program. using System; using System.Diagnostics; using System.Linq;   namespace ObfuscateMe {     class Program     {                static void Main(string[] args)         {               Console.WriteLine(IsProcessOpen("notepad")); //Returns a True or False depending if you have notepad running.             Console.ReadLine();         }             public static bool IsProcessOpen(string name)         {             return Process.GetProcesses().Any(clsProcess => clsProcess.ProcessName.Contains(name));         }     } }   Pretend, that this is a commercial application. The hacker will only have the executable and maybe a few config files, etc. After reviewing the executable, he can determine if it was produced in .NET by examing the file in ILDASM or Redgate’s Reflector. We are going to examine the file using RedGate’s Reflector. Upon launch, we simply drag/drop the exe over to the application. We have the following for the Main method:   and for the IsProcessOpen method:     Without any other knowledge as to how this works, the hacker could export the exe and get vs project build or copy this code in and our application would run. Using Reflector output. using System; using System.Diagnostics; using System.Linq;   namespace ObfuscateMe {     class Program     {                static void Main(string[] args)         {               Console.WriteLine(IsProcessOpen("notepad"));             Console.ReadLine();         }             public static bool IsProcessOpen(string name)         {             return Process.GetProcesses().Any<Process>(delegate(Process clsProcess)             {                 return clsProcess.ProcessName.Contains(name);             });         }       } } The code is not identical, but returns the same value. At this point, with a little bit of effort you could prevent the hacker from reverse engineering your code so quickly by using Eazfuscator.NET. Eazfuscator.NET is just one of many programs built for this. Visual Studio ships with a community version of Dotfoscutor. So download and load Eazfuscator.NET and drag/drop your exectuable/project into the window. It will work for a few minutes depending if you have a quad-core or not. After it finishes, open the executable in RedGate Reflector and you will get the following: Main After Obfuscation IsProcessOpen Method after obfuscation: As you can see with the jumbled characters, it is not as easy as the first example. I am aware of methods around this, but it takes more effort and unless the hacker is up for the challenge, they will just pick another program. This is also helpful if you are a consultant and make clients pay a yearly license fee. This would prevent the average software developer from jumping into your security routine after you have left. I hope this article helped someone. If you have any feedback, please leave it in the comments below.

  • Problem with sprite direction and rotation

    - by user2236165
    I have a sprite called Tool that moves with a speed represented as a float and in a direction represented as a Vector2. When I click the mouse on the screen the sprite change its direction and starts to move towards the mouseclick. In addition to that I rotate the sprite so that it is facing in the direction it is heading. However, when I add a camera that is suppose to follow the sprite so that the sprite is always centered on the screen, the sprite won't move in the given direction and the rotation isn't accurate anymore. This only happens when I add the Camera.View in the spriteBatch.Begin(). I was hoping anyone could maybe shed a light on what I am missing in my code, that would be highly appreciated. Here is the camera class i use: public class Camera { private const float zoomUpperLimit = 1.5f; private const float zoomLowerLimit = 0.1f; private float _zoom; private Vector2 _pos; private int ViewportWidth, ViewportHeight; #region Properties public float Zoom { get { return _zoom; } set { _zoom = value; if (_zoom < zoomLowerLimit) _zoom = zoomLowerLimit; if (_zoom > zoomUpperLimit) _zoom = zoomUpperLimit; } } public Rectangle Viewport { get { int width = (int)((ViewportWidth / _zoom)); int height = (int)((ViewportHeight / _zoom)); return new Rectangle((int)(_pos.X - width / 2), (int)(_pos.Y - height / 2), width, height); } } public void Move(Vector2 amount) { _pos += amount; } public Vector2 Position { get { return _pos; } set { _pos = value; } } public Matrix View { get { return Matrix.CreateTranslation(new Vector3(-_pos.X, -_pos.Y, 0)) * Matrix.CreateScale(new Vector3(Zoom, Zoom, 1)) * Matrix.CreateTranslation(new Vector3(ViewportWidth * 0.5f, ViewportHeight * 0.5f, 0)); } } #endregion public Camera(Viewport viewport, float initialZoom) { _zoom = initialZoom; _pos = Vector2.Zero; ViewportWidth = viewport.Width; ViewportHeight = viewport.Height; } } And here is my Update and Draw-method: protected override void Update (GameTime gameTime) { float elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; TouchCollection touchCollection = TouchPanel.GetState (); foreach (TouchLocation tl in touchCollection) { if (tl.State == TouchLocationState.Pressed || tl.State == TouchLocationState.Moved) { //direction the tool shall move towards direction = touchCollection [0].Position - toolPos; if (direction != Vector2.Zero) { direction.Normalize (); } //change the direction the tool is moving and find the rotationangle the texture must rotate to point in given direction toolPos += (direction * speed * elapsed); RotationAngle = (float)Math.Atan2 (direction.Y, direction.X); } } if (direction != Vector2.Zero) { direction.Normalize (); } //move tool in given direction toolPos += (direction * speed * elapsed); //change cameracentre to the tools position Camera.Position = toolPos; base.Update (gameTime); } protected override void Draw (GameTime gameTime) { graphics.GraphicsDevice.Clear (Color.Blue); spriteBatch.Begin (SpriteSortMode.BackToFront, BlendState.AlphaBlend, null, null, null, null, Camera.View); spriteBatch.Draw (tool, new Vector2 (toolPos.X, toolPos.Y), null, Color.White, RotationAngle, originOfToolTexture, 1, SpriteEffects.None, 1); spriteBatch.End (); base.Draw (gameTime); }

  • Too complex/too many objects?

    - by Mike Fairhurst
    I know that this will be a difficult question to answer without context, but hopefully there are at least some good guidelines to share on this. The questions are at the bottom if you want to skip the details. Most are about OOP in general. Begin context. I am a jr dev on a PHP application, and in general the devs I work with consider themselves to use many more OO concepts than most PHP devs. Still, in my research on clean code I have read about so many ways of using OO features to make code flexible, powerful, expressive, testable, etc. that is just plain not in use here. The current strongly OO API that I've proposed is being called too complex, even though it is trivial to implement. The problem I'm solving is that our permission checks are done via a message object (my API, they wanted to use arrays of constants) and the message object does not hold the validation object accountable for checking all provided data. Metaphorically, if your perm containing 'allowable' and 'rare but disallowed' is sent into a validator, the validator may not know to look for 'rare but disallowed', but approve 'allowable', which will actually approve the whole perm check. We have like 11 validators, too many to easily track at such minute detail. So I proposed an AtomicPermission class. To fix the previous example, the perm would instead contain two atomic permissions, one wrapping 'allowable' and the other wrapping 'rare but disallowed'. Where previously the validator would say 'the check is OK because it contains allowable,' now it would instead say '"allowable" is ok', at which point the check ends...and the check fails, because 'rare but disallowed' was not specifically okay-ed. The implementation is just 4 trivial objects, and rewriting a 10 line function into a 15 line function. abstract class PermissionAtom { public function allow(); // maybe deny() as well public function wasAllowed(); } class PermissionField extends PermissionAtom { public function getName(); public function getValue(); } class PermissionIdentifier extends PermissionAtom { public function getIdentifier(); } class PermissionAction extends PermissionAtom { public function getType(); } They say that this is 'not going to get us anything important' and it is 'too complex' and 'will be difficult for new developers to pick up.' I respectfully disagree, and there I end my context to begin the broader questions. So the question is about my OOP, are there any guidelines I should know: is this too complicated/too much OOP? Not that I expect to get more than 'it depends, I'd have to see if...' when is OO abstraction too much? when is OO abstraction too little? how can I determine when I am overthinking a problem vs fixing one? how can I determine when I am adding bad code to a bad project? how can I pitch these APIs? I feel the other devs would just rather say 'its too complicated' than ask 'can you explain it?' whenever I suggest a new class.

  • faster implementation of sum ( for Codility test )

    - by Oscar Reyes
    How can the following simple implementation of sum be faster? private long sum( int [] a, int begin, int end ) { if( a == null ) { return 0; } long r = 0; for( int i = begin ; i < end ; i++ ) { r+= a[i]; } return r; } EDIT Background is in order. Reading latest entry on coding horror, I came to this site: http://codility.com which has this interesting programming test. Anyway, I got 60 out of 100 in my submission, and basically ( I think ) is because this implementation of sum, because those parts where I failed are the performance parts. I'm getting TIME_OUT_ERROR's So, I was wondering if an optimization in the algorithm is possible. So, no built in functions or assembly would be allowed. This my be done in C, C++, C#, Java or pretty much in any other. EDIT As usual, mmyers was right. I did profile the code and I saw most of the time was spent on that function, but I didn't understand why. So what I did was to throw away my implementation and start with a new one. This time I've got an optimal solution [ according to San Jacinto O(n) -see comments to MSN below - ] This time I've got 81% on Codility which I think is good enough. The problem is that I didn't take the 30 mins. but around 2 hrs. but I guess that leaves me still as a good programmer, for I could work on the problem until I found an optimal solution: Here's my result. I never understood what is those "combinations of..." nor how to test "extreme_first"

  • Delphi label and asm weirdness?

    - by egon
    I written an asm function in Delphi 7 but it transforms my code to something else: function f(x: Cardinal): Cardinal; register; label err; asm not eax mov edx,eax shr edx, 1 and eax, edx bsf ecx, eax jz err mov eax, 1 shl eax, cl mov edx, eax add edx, edx or eax, edx ret err: xor eax, eax end; // compiled version f: push ebx // !!! not eax mov edx,eax shr edx, 1 and eax, edx bsf ecx, eax jz +$0e mov eax, 1 shl eax, cl mov edx, eax add edx, edx or eax, edx ret err: xor eax, eax mov eax, ebx // !!! pop ebx // !!! ret // the almost equivalent without asm function f(x: Cardinal): Cardinal; var c: Cardinal; begin x := not x; x := x and x shr 1; if x <> 0 then begin c := bsf(x); // bitscanforward x := 1 shl c; Result := x or (x shl 1) end else Result := 0; end; Why does it generate push ebx and pop ebx? And why does it do mov eax, ebx? It seems that it generates the partial stack frame because of the mov eax, ebx. This simple test generates mov eax, edx but doesn't generate that stack frame: function asmtest(x: Cardinal): Cardinal; register; label err; asm not eax and eax, 1 jz err ret err: xor eax, eax end; // compiled asmtest: not eax and eax, $01 jz +$01 ret xor eax, eax mov eax, edx // !!! ret It seems that it has something to do with the label err. If I remove that I don't get the mov eax, * part. Why does this happen? Made a bug report on Quality Central.

  • XNA Alpha Blending to make part of a texture transparent

    - by David
    What I am trying to do is use alpha blending in XNA to make part of a drawn texture transparent. So for instance, I clear the screen to some color, lets say Blue. Then I draw a texture that is red. Finally I draw a texture that is just a radial gradient from completely transparent in the center to completely black at the edge. What I want is the Red texture drawn earlier to be transparent in the same places as the radial gradient texture. So you should be able to see the blue back ground through the red texture. I thought that this would work. GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(SpriteBlendMode.None); spriteBatch.Draw(bg, new Vector2(0, 0), Color.White); spriteBatch.End(); spriteBatch.Begin(SpriteBlendMode.None); GraphicsDevice.RenderState.AlphaBlendEnable = true; GraphicsDevice.RenderState.AlphaSourceBlend = Blend.One; GraphicsDevice.RenderState.AlphaDestinationBlend = Blend.Zero; GraphicsDevice.RenderState.SourceBlend = Blend.Zero; GraphicsDevice.RenderState.DestinationBlend = Blend.One; GraphicsDevice.RenderState.BlendFunction = BlendFunction.Add; spriteBatch.Draw(circle, new Vector2(0, 0), Color.White); spriteBatch.End(); GraphicsDevice.RenderState.AlphaBlendEnable = false; But it just seems to ignore all my RenderState settings. I also tried setting the SpriteBlendMode to AlphaBlend. It blends the textures, but that is not the effect I want. Any help would be appreciated.

    Hi I am making a program to open and close the cd reader in which I have thought to write data to CD, the problem is the basis of the problem, which use "uses Windows 'and' uses MMSystem" but the problem is that when I use both at the same time being "uses Windows, MMSystem" gives an error and the program does not compile, I am using Delphi 2010, the strange thing is that when I use only one either Windows or MMSystem works fine and compiles. The error when I try to compile is: 'Could not find program' The code in question is this: mciSendString ('Set cdaudio door open wait', nil, 0, handle); I have two things to ask you first is how I avoid the error when using the two (Windows and MMSystem) and the other question was if he could open the CD player without using MMSystem, bone using Windows API, but not where to start The source : program Project1; {$APPTYPE CONSOLE} uses SysUtils,Windows,MMSystem; procedure opencd; begin mciSendString('Set cdaudio door open wait', nil, 0, 0); end; begin try Writeln('test'); except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.

  • VB6 ImageList Frm Code Generation

    - by DAC
    Note: This is probably a shot in the dark, and its purely out of curiosity that I'm asking. When using the ImageList control from the Microsoft Common Control lib (mscomctl.ocx) I have found that VB6 generates FRM code that doesn't resolve to real property/method names and I am curious as to how the resolution is made. An example of the generated FRM code is given below with an ImageList containing 3 images: Begin MSComctlLib.ImageList ImageList1 BackColor = -2147483643 ImageWidth = 100 ImageHeight = 45 MaskColor = 12632256 BeginProperty Images {2C247F25-8591-11D1-B16A-00C0F0283628} NumListImages = 3 BeginProperty ListImage1 {2C247F27-8591-11D1-B16A-00C0F0283628} Picture = "Form1.frx":0054 Key = "" EndProperty BeginProperty ListImage2 {2C247F27-8591-11D1-B16A-00C0F0283628} Picture = "Form1.frx":3562 Key = "" EndProperty BeginProperty ListImage3 {2C247F27-8591-11D1-B16A-00C0F0283628} Picture = "Form1.frx":6A70 Key = "" EndProperty EndProperty End From my experience, a BeginProperty tag typically means a compound property (an object) is being assigned to, such as the Font object of most controls, for example: Begin VB.Form Form1 Caption = "Form1" ClientHeight = 10950 ClientLeft = 60 ClientTop = 450 ClientWidth = 7215 BeginProperty Font Name = "MS Serif" Size = 8.25 Charset = 0 Weight = 400 Underline = 0 'False Italic = -1 'True Strikethrough = 0 'False EndProperty End Which can be easily seen to resolve to VB.Form.Font.<Property Name>. With ImageList, there is no property called Images. The GUID associated with property Images indicates type ListImages which implements interface IImages. This type makes sense, as the ImageList control has a property called ListImages which is of type IImages. Secondly, properties ListImage1, ListImage2 and ListImage3 don't exist on type IImages, but the GUID associated with these properties indicates type ListImage which implements interface IImage. This type also makes sense, as IImages is in fact a collection of IImage. What doesn't make sense to me is how VB6 makes these associations. How does VB6 know to make the association between the name Images - ListImages purely because of an associated type (provided by the GUID) - perhaps because it's the only property of that type? Secondly, how does it resolve ListImage1, ListImage2 and ListImage3 into additions to the collection IImages, and does it use the Add method? Or perhaps the ControlDefault property? Perhaps VB6 has specific knowledge of this control and no logical resolution exists?

  • Exchanging strings (PChar) between a Freepascal compiled DLL and a Delphi compiled EXE

    - by John Riche
    After a lot of experimentations, I found a way to exchange PChar from a FreePascal compiled DLL with a Delphi compiled EXE. I'm in charge of both the DLL and EXE source code but one MUST BE in FreePascal and the other one in Delphi. My solution involves the following methods in the DLL: function GetAString(): PChar; var aString: string; begin aString := 'My String'; result := StrAlloc(length(aString) + 1); StrPCopy(result, aString); end; procedure FreeString(aString: PChar); begin StrDispose(aString); end; And from the Delphi EXE, to call the GetAString method, I need to Call the GetAString method, save the PChar to an actual Delphi String and call the FreeString method. Is this the best way of exchanging a string from a FreePascal DLL with a Delphi EXE ? Can I avoid the call to FreeString from Delphi ? And finally, if that's the correct solution, how will it behave with Delphi 2010 and the WideString by default: do I need to force WidePChar in FreePascal too ?

  • delphi Ado (mdb) update records

    - by ml
    I´m trying to copy data from one master table and 2 more child tables when i select one record in the master table i copy all the fields from that table for the other (table1 copy from ADOQuery the selected record) procedure TForm1.copyButton7Click(Sender: TObject); SQL.Clear; SQL.Add('SELECT * from ADOQuery'); SQL.Add('Where numeracao LIKE ''%'+NInterv.text);// locate record selected in Table1 NInterv.text) Open; // initiate copy of records begin while not tableADoquery.Eof do begin Table1.Last; Table1.Append;// how to append if necessary! Table1.Edit; Table1.FieldByName('C').Value := ADoquery.FieldByName('C').Value; Table1.FieldByName('client').Value := ADoquery.FieldByName('client').Value; Table1.FieldByName('Cnpj_cpf').Value := ADoquery.FieldByName('Cnpj_cpf').Value; table1.Post; table2.next;/// end; end; //How can i update the TableChield, TableChield1 field´s at the same time? do the same for the child tables TableChield <= TableChield_1 TableChield1 <= TableChield_2 thanks

  • Convert CRC-CCITT Kermit 16 DELPHI code to C#

    - by Mehdi Anis
    I am working on a function that will give me a Kermit CRC value from a HEX string. I have a piece of code in DELPHI. I am a .NET developer and need the code in C#. function CRC_16(cadena : string):word; var valuehex : word; i: integer; CRC : word; Begin CRC := 0; for i := 1 to length(cadena) do begin valuehex := ((ord(cadena[i]) XOR CRC) AND $0F) * $1081; CRC := CRC SHR 4; CRC := CRC XOR valuehex; valuehex := (((ord(cadena[i]) SHR 4) XOR LO(CRC)) AND $0F); CRC := CRC SHR 4; CRC := CRC XOR (valuehex * $1081); end; CRC_16 := (LO(CRC) SHL 8) OR HI(CRC); end; I got the code from this webpage: Kermit CRC in DELPHI I guess that Delphi function is correct. If any one can please convert the code to C# that will be great. I tried to convert to C#, but got lost in WORD data type and the LO function of Delphi. Thank you all.
