  • Is there a faster alternative to using textures in XNA?

    - by Matthew Bowen
    I am writing a map editing program for a 2D game using XNA. To create a Texture2D for all of the tiles that a map requires takes too long. Are there any alternatives to using textures for drawing with XNA? I attempted to create just one texture per tile set instead of a texture for every tile in a tile set, but there is a limit to the size of textures and I could not fit all the tiles of a tile set into one texture. Currently the program contains all the would-be textures in memory as Bitmap objects. Is there a way to simply draw a Bitmap object to the screen in XNA? I have searched but I cannot find any information on this. This approach would avoid having to create textures altogether, however any tinting or effects I would have to do to the bitmap directly. Any help would be very much appreciated. Thanks

  • How to create windows form to display properly in all monitors?

    - by madhu bn
    I have created a windows form using (vs.net 2008 and vb.net as programming lanugage). Functionality part is working fine as expected. My issues is that, when i run my application in different machines, the form display is not proper accross the monitory screen. In some machines i noticed extra space on leftside of the container. In some other machine's it is vice versa. If you maximize or restore the form, the size varies. I tried to check the window form design on different machines using visual studio 2008, there also the form design looks differently. Please give me the solution to fix this issue. Thanks in advance.

  • How to set probability for a targetSprite shooting accuracy in shooting game ?

    - by srikanth rongali
    Hi, My code is ion cocos2D. I have written code for generating the bullets from the enemy gun for every 0.3seconds. The enemySprite is in right side of the screen in (land scape mode) at winSize.height/2. the bullet starts from the same point and reach the player's end. I used rand() to generate y-coordinate for the bullet to hit on player side. Now, if the bullet bounded rectangle meets the player bounded rectangle the enemy won. If it misses enemy shoots again after 0.3 seconds. Every thing is fine up to here for me. But I have 10 enemies and each have accuracy of hitting player of probabilities ranging from 0.80 to 1.0. First enemy probability is .80 and 10 enemy's is 1.0. How can I adjust the probability for enemy such that it runs according to its probability. Player also hits the enemy.

  • Are there any online database schema drawing tools?

    - by Pure.Krome
    Hi folks, i wish to draw up some database schemas. Eg, table 1 has zero to many rows in table 2, etc. It's purely for visual purposes (eg. no sql code, etc). Are there any online tools / website that offer this? (please don't say: Use Sql Server Database Diagrams, print screen, upload to image hosting service). thanks :) EDIT: Please take note of the keyword - ONLINE. I don't want any desktop solutions (because I already have one of these).

  • JComponent undock effect

    - by Christo Du Preez
    I'm trying to accomplish an undock effect for a custom Swing JComponent. By default the component is used inside a form along with other components. I want to be able to maximize this component to use the whole screen and then be able to dock it again. So far I've tested public void showDialog() { JFrame mainFrame = App.getApplication().getMainFrame(); JDialog dialog = new JDialog(mainFrame); dialog.setModal(true); dialog.setSize(800, 600); //Set to 80x660 for now dialog.add(this); //This is my JComponent dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); dialog.setVisible(true); } This gives me desired effect but when closing the dialog my component doesn't receive events no more. How can I prevent this? Or is there perhaps a better way to accomplish this?

  • VS 2008 SP1 text editor flickering over remote desktop connection

    - by AltairDusk
    I am connecting from a Windows 7 x64 machine to my dev machine running Windows XP SP3 using the built in remote desktop client. For most apps it works fine with no problems, for Visual Studio whenever I am typing the entire text editor keeps redrawing. I stumbled across this question: http://stackoverflow.com/questions/873849/vs-2008-sp1-over-remote-desktop-constant-repainting and I have tried all of the suggestions in it to no effect, including resetting all VS settings back to default then disabling the suggested settings. Has anyone found a reliable solution to this? I feel like I'm going insane with the screen constantly refreshing when I'm working from home. Some additional information: Remote Desktop is set to run at 1680x1050, 15bit color, Low-speed broadband for the experience setting with all but Visual styles and Persistent bitmap caching unchecked. Visual Studio 2008 Team System is running on the dev machine with Service Pack 1 and Power Commands installed.

  • Modal View Controller with keyboard on landscape iPad changes location when dismissed

    - by Roi
    I present a modal view controller on my on my iPad with UIModalPresentationFormSheet presentation style and UIModalTransitionStyleCoverVertical transition style. The Modal View Controller contains a UIWebView with some TextFields on it. When the user taps one of the text fields the keyboard comes up. I have noticed that in landscape mode after the keyboard is shown, if I try to dismiss the modal view controller with animation the view changes its position from the center of the screen to the left side just before the animation starts.. This happens only if the keyboard is up and only in landscape mode on the iPad. If the user closes the modal view without pressing on any text field this doesn't happen. Anyone familiar with this strange behavior?

  • Execute an autocommand only once

    - by Andrej M.
    I have an issue with using GVim on Windows. I have set up the following in my .vimrc: if has("gui_running") autocmd VIMEnter * :source C:/session.vim endif Unfortunately this creates a problem. If I'm a the top of the file and try to move up a line (k), the screen flashes. If I hold the key for just a second it will flash a few dozen times, it is really nasty too look at. I've tried using GUIEnter instead but I got the same results. The docs mention that I can fire an autocommand only once, but I couldn't figure out the exact syntax. Care to help?

  • DataGridView lags for a second with large data updates

    - by alexD
    I have a DataGridView with about 400 rows and 10 columns. When the user first displays this table, it receives all of the data from the server and populates the table. The DGV uses a DataTable as it's data source, and when updating the DataTable I use row.BeginEdit/EndEdit and acceptChanges, but when the View itself is updated it lags for a second while all of the DGV is being updated. I am wondering if there is a way to make this smooth, so that for example, if the user is scrolling through the data and it updates, it won't interrupt the scrolling. Or if the user is moving the display around the screen and it updates, it won't interrupt. Is there an easy way to do this? If not, is there away to prevent the DGV from updating the view until all events have ended so it won't be repainted until the user stops scrolling, dragging, etc ?

  • Creating a child process on Unix systems?

    - by Hakan Svensson
    I'm trying to create a child process in another process. I am writing both the programs in C language. First I write a dummy process which will be the child process. What it is doing is only to write a string on the screen. It works well on its own. Then I write another program which will be the parent process. However, I can't make it happen. I'm trying to use fork and execl functions together, but I fail. I also want the child process does not terminate until the parent process terminates. How should I write the parent process? Thanks.

    - by Hasan Gürsoy
    I have a full page flash animation. When this page is open at Firefox and I want to minimize or re-size Firefox screen, minimize button starts to blink and Firefox does not take any action till this tab is closed. There is not too much code in the flash file. What can cause this? Also this could not be related with full page. I saw other flash files doing same thing. As I remember same problem at Daily Motion. When trying to switch tab nothing happens till I stop video or close the tab.

  • Adding Listeners at runtime? - Java MVC

    - by Halo
    My model in my MVC pattern, generates components at runtime and gives them to the View to be displayed on the screen through update() method (you know, model is the observable and the view is the observer). But I also need to add listeners to these components, and the controller has the listener methods (because they say the MVC pattern is like this) and it's not involved in this update process. So I can't add the listeners at runtime, but only in the controller's constructor at startup. I've got an idea, that is making the controller the observer and then giving the data to the view, as well as adding the listeners. Do you think this would be OK?

  • Creating an Improved Digital Zoom

    - by Kazar
    Hey, Ok, so I have a given video source (for the sake of the example, it is a camera). It does not have optical zoom, but we supply digital zoom instead. Now this digital zoom is pretty simple, simply cropping the image to a specified portion, and filling the screen with that portion. The problem is that the zoomed video can have pretty rubbish quality when the digital zoom is enabled. I am wondering if anyone knows of an approach by which a higher quality of digital zoom can be achieved in real-time. The software is on Windows, and the video is rendered using DirectShow, but it isn't a platform solution I'm necessarily after, more just a better approach to the problem. Cheers

  • Process touches behind the UINavigationBar

    - by Reed Olsen
    In my application, I'm displaying a fullscreen image in a 320 x 480 frame. After I display the image, I fade the navigation bar out to allow the user to see the whole picture. When the user taps in the area where the navigation bar was, I would like to bring the navigation bar back. This is very similar to what happens in the iPhone Photos app. Unfortunately, after I've hidden the UINavigationBar, I can't process touches on the screen where the navigation bar once was. I believe this is because the origin of the parent view is right below the navigation bar: How can I process touches in this area to bring the nav bar back?

  • Rotate image in Quartz? Image is upside down! (iPhone)

    - by Johannes Jensen
    I don't want to transform the ENTIRE context. I'm making a game with Quartz, and I'm drawing my player with lines, rects and ellipses. And then I have diamong.png which I rendered at 0,0 in the top left of the screen. Problem is... It renders upside down! How would I rotate it 180 degrees? Here's some of my code: CGImageRef diamondImage = CGImageRetain([UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"Diamond.png" ofType:nil]].CGImage); CGContextDrawImage(context, CGRectMake(0, 0, 32, 24), diamondImage); If it's of any help, I'm using Landscape mode, with home button to the right. It's defined both in my .plist, and in my ViewController's -shouldAutorotateToInterfaceOrientation:interfaceOrientation: How would I rotate/transform it?

  • How to get the quickfix timestamp?

    - by yves Baumes
    I've seen in quickfix doxygen documentation that it generates an utc timestamp as soon as it has received a FIX message from a socket file. Have a look in ThreadedSocketConnection::processStream(), it calls then m_pSession->next( msg, UtcTimeStamp() ); I would like to get that timestamp, because I need it to screen network and QuickFix lib latencies. I didn't find a way to get it from FixApplication::fromApp() callback or 'Log::onIncoming()' callback. As I am newbie with quickfix I would like to know if I missed something in the Quickfix documentation. Did anybody ever done that before? Of course there is other solutions, but for homogeneity with others market acces applications I maintain, I would prefer to avoid them. For instance, I would prefer not to modify QuickFix code source. And I would like to avoid re-write the application logic that quickfix provide me, quickfix helpping me only for message decoding.

  • Android back button does not restart activity?

    - by Chris
    My app intiates an activity. On the click of a button, the app opens up the browser with a webpage. When I hit the back button, it comes back to my initial activity screen, but does not resume or restart the activity. When I put all the layout code and activity code in onResume instead of onCreate, the activity gets restarted. My question is whether this is the right way to go about it? Can I use onResume to draw my layout and initiate the activity, or is this poor design? When the browser fires up, does the initial activity forget its layout? Please let me know what you suggest. Thanks Chris

  • $().mouseMove <-- Empty selector in jQuery 1.4

    - by Matrym
    The following bit of code breaks in the upgrade to jquery 1.4: $().mousemove( function (e) { defaults.mouseX = e.pageX; defaults.mouseY = e.pageY; }); }; What appeared to be a reasonable fix was adding "html" as the selector, ex: $("html"). The fix works fine - except now when the user mouses off the page, it doesn't register the mouse position beyond the boundaries. When attempting to use the mouse position for a drag, for example, the amount of movement beyond the screen is really important. Anyone got any ideas? Thanks in advance.
