  • Differences in IE8 behavior between XP, Vista, Win7?

    - by Piskvor
    Is there any significant difference in behavior (HTML, CSS, Javascript, ...) with Internet Explorer 8 on different operating systems? In other words, will a web page work the same way across IE8+XP, IE8+Vista and IE8+Win7, or are there some significant differences? (I'm aware that installed plugins and fonts will have an impact, but that's a bit outside my scope at the moment; assuming compatibility mode X-UA-Compatible: IE=8 or edge) Although The IEBlog contains very useful information, I haven't found this data there - so I'm assuming that there should not be any difference. However, search has turned up this (vague) question: "IE8 on XP: looks great! IE8 on Vista: looks terrible". Will have to check IE8+{XP,V,7} in VM in the meantime.

    - by Yatenda Goel
    I want to give XP Look and Feel to my Java Desktop Appliction, regardless of the platform it will run. I came to know that since JDK 1.4, Sun Microsystems has officially released a look and feel for XP - com.sun.java.swing.plaf.windows.WindowsLookAndFeel I am using Java 1.6 but when I didn't find any package named windows in javax.swing.plaf package. Q1. How can I use the XP Look and Feel? Q2. Will using this look and feel will appear same on all platforms (mac, solaris, linux)?

  • How to prevent Windows XP from stealing my input Ctrl-Space which is meant for Emacs

    - by Dean
    I am learning and using Emacs. What I found annoying is that Ctrl-Space input will be stolen by Windows XP to switch the language bar instead of setting the mark in Emacs. The "language bar" is the native input languages selection such as Chinese keyboard other than English keyboard. Is there a way to temporarily prevent XP from stealing it? I have disabled the language bar from "Regional and language options" from Control Panel but the problem still exists. It doesn't happen on my Windows 2000 desktop at office but it happens on my work Windows XP laptop. Thank you very much.

  • CM_Get_Device_ID gets correct values from win7 but not xp

    - by Jon W. Jones
    When using CM_Get_Device_ID(...) I am getting the correct value from windows 7. When using windows xp I am getting an incorrect value. For Example, on xp I get "USB\VID_2132&PID_0001\5&36FF4167&0&7" and on 7 I get "USB\VID_2132&PID_0001\413031000576". The value after the \ on PID is our serial number and it is correct on 7 but xp keeps giving back what appears to be a nonsensical value. My question is has anyone else encountered this and know of a workaround?

  • 3D Screensaver interfering with WPF application (Windows XP)

    - by Andrew Keith
    I have a fairly large application that uses WPF for its user interface. I recently found an unusual defect regarding 3D screensavers. The 3D screensavers 3D FlowerBox,3D Flying Objects,3D Pipes,3D Text causes 1 of my WPF windows to disappear when the screensaver activates. Other screensavers are fine. My application only encounters this problem on Windows XP. I have some experience with DirectX. When a 3D screensavers activates, the d3d device context will be switched to exclusive mode. I reckon that WPF has trouble restoring the device context when the device switches back to cooperative mode (hence why its only affecting windows XP) Has anyone seen such a scenario occur before ? Is there a remedy for the problem ? Windows XP SP3, DirectX 9.0c, .NET 3.5

  • Windows 7 - XP Mode - Apache

    - by Howard
    I've setup Virtual PC and XP Mode on my Windows 7 Pro. Using Apache 2.0.52 I have no problems having my website up and running on the Windows 7 machine. But Under VPC/XP Mode the best I can do is Localhost mode. What do I need to do to enable http connections? I need the XP Mode as besides the website I also run a Web BBS and a Dos based (via telnet) BBS. Some of the apps in the Dos BBS just won't work under 64 bit, no matter what setting (capability) are used. Thanks in advance...

  • Eclipse randomly exits after installation of Blackberry plugin/SDK

    - by canadiancreed
    Hello all Since adding the Blackberry Java classes from their website into eclipse, I've had it where eclipse will randomly close, with no discernible pattern, rhyme, error or reason. Here is the environment/software packages that I am using: Windows XP SP2 Eclipse v3.5.1 Blackberry Java Plugin v1.1.1.200911111641-15 Blackberry Java SDK 4.5.0.21 I've tried the usual steps of complete uninstall and reinstallation of Eclipse and the accompanying plugins on multiple systems with the same configuration, including one that had a fresh install of Windows XP SP2. Upgrading to Eclipse 3.6 didn't work (the plugin wont' install as it's the wrong version), nor the downgrade to 3.4 for the same reason. I also increased the heap size to 512 (system has two gigs of memory) as some research into Eclipse doing this type of thing with Groovy was resolved that way, but again, no dice. Eclipse works great when the blackberry plugins are not installed, and no entries of errors or issues in the event log are helping to show what the issue with these plug-ins might be. So if anyone has ran into this issue, and even better, has a solution, I'd love to hear about it. Thanks in advance. EDIT: An additional to my issue, autoComplete with the Blackberry SDK seems to make this extremely unstable, like almost a guaranteed crash. Is this fixable at all?

  • Is it possible to run my Windows Form application in Windows CE platform?

    - by Fakhrul
    I am new in Windows CE development and never done it yet. Need some advise from the expert in here. In our current project, we are developing a client-server application. The client side is using a windows form application that are base on Windows XP OS while the server is a web base application. This question are related to the client application (Windows Form). This application are using Sql Server Express Edition for data storage. The data is stored in XML object format. It also can transfer a data from client to server via web service. It also interact with hardware such as Magnetic Stripe Reader, Contactless Smart Card Reader, and a thermal printer. Most of the communication between hardware device and systems are base on Serial Port. It is use standard app.config for the configuration and is a multi threaded application. There is a new requirement to use a Handheld device which is use a Windows CE platform. This handheld included the required equipment such as Contactless Smart Card Reader, Printer and Magnetic Stripe Reader. Instead of developing a new client application, is it possible to me to convert my current application that are base on Windows XP to Windows CE? If yes, how can I do that? If no, is it any other brilliant suggestion to do this? Thanks in advance. Software Engineer

  • Windows theme affecting ListView header

    - by LihO
    I've created new Windows Forms Application (C#) with one simple form containing ListView. Then I changed the View Property to Details and increased the size of the font used in this ListView and here's the result: This is how it looks on Windows XP with Windows Classic theme: and here's the result with Windows XP theme: Creating the same Windows Forms Application in Visual C++ instead of C# yields same result. EDIT : Thanks to Kamil Lach, we already know that Visual Styles is what makes the appearance of ListView change. This can be avoided either by removing Application.EnableVisualStyles() call or by changing the Application.VisualStyleState. Both of these solutions yield the following result: This looks fine, but this change affects the appearance of other controls which is not good. I'd like my ListView to be the only control that is not affected by Visual Styles. I've also found similar questions that try to deal with it: Can you turn off visual styles/theming for just a single windows control? How do I disable visual styles for just one control, and not its children? Unfortunately, none of mentioned solutions works. Any C# solution that would make the ListView header have the correct height would be appreciated.

  • 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.

  • Setting up a minimalist linux environment

    - by Nate
    All right, I've been messing around with various linux distros and a variety of window managers (I seem to change operating systems like most people change their pants), and I've gotten to the point where I know what I want but I'm not sure the best way to set it up. Here's what I want out of my programming machine: I don't want a status bar. I don't want a menu bar. When there are no windows open, the screen should show my desktop background and nothing else. I'll use alt+f2 to run things, and my shell prompt will tell me my battery life and the time. I'll open network controls and volume controls when I need them, no need for them to pollute the screen all the time. I want a good, simple terminal emulator. I'll be using it with tmux. It should have no title bar and, if possible, no app frame. It's ok if I have to run it in full screen mode to remove the app frame, but only if it still plays nicely with alt-tab and workspaces. I want a dirt-simple window manager. It needs to support transparency: I don't have a lot of screen real-estate and I often overlay the terminal on the browser and type out commands. I don't want a tiling-only system, for the above reason. Bonus points for tiling and overlaying. I'd like multiple workspaces. I prefer to have one gui per workspace. If I could 'pin' the terminal emulator to always show up in each workspace, that's bonus points. If not, I can have a terminal emulator in each workspace attached to the same tmux instance. I'd like a way to set up a keypress that always takes me to the current open terminal emulator. Currently, 90% of the time I only have two windows open: the terminal emulator and something else. In this scenario, alt-tab works like a toggle between the two. If I have another gui open (like a developer window with a web browser), this throws a wrench in my workflow. I'd like a way to assign, for example, 'super-T' to switch to the first open terminal emulator. Bonus points if I can also assign 'super-B' (or whatever) to switch to the first open browser. So far I've been messing around with gnome and tweaking it heavily to match my preferences, but that seems like overkill and I can never get it quite right. I've toyed with xmonad, but it's more for handling many windows, and I usually only have the two. and am considering fluxbox, but I was wondering if any of your minimalists out there had suggestions that might better match my workflow. I'm sick of fighting the window manager, I just want it to get out of my way. Edit: To make things clear, I am not considering switching to a mac/windows environment. I find programming in windows to be a bore, and I have no interest in buying new (read: mac) hardware. Thanks! -Nate

  • Exploring TCP throughput with DTrace

    - by user12820842
    One key measure to use when assessing TCP throughput is assessing the amount of unacknowledged data in the pipe. This is sometimes termed the Bandwidth Delay Product (BDP) (note that BDP is often used more generally as the product of the link capacity and the end-to-end delay). In DTrace terms, the amount of unacknowledged data in bytes for the connection is the different between the next sequence number to send and the lowest unacknoweldged sequence number (tcps_snxt - tcps_suna). According to the theory, when the number of unacknowledged bytes for the connection is less than the receive window of the peer, the path bandwidth is the limiting factor for throughput. In other words, if we can fill the pipe without the peer TCP complaining (by virtue of its window size reaching 0), we are purely bandwidth-limited. If the peer's receive window is too small however, the sending TCP has to wait for acknowledgements before it can send more data. In this case the round-trip time (RTT) limits throughput. In such cases the effective throughput limit is the window size divided by the RTT, e.g. if the window size is 64K and the RTT is 0.5sec, the throughput is 128K/s. So a neat way to visually determine if the receive window of clients may be too small should be to compare the distribution of BDP values for the server versus the client's advertised receive window. If the BDP distribution overlaps the send window distribution such that it is to the right (or lower down in DTrace since quantizations are displayed vertically), it indicates that the amount of unacknowledged data regularly exceeds the client's receive window, so that it is possible that the sender may have more data to send but is blocked by a zero-window on the client side. In the following example, we compare the distribution of BDP values to the receive window advertised by the receiver (10.175.96.92) for a large file download via http. # dtrace -s tcp_tput.d ^C BDP(bytes) 10.175.96.92 80 value ------------- Distribution ------------- count -1 | 0 0 | 6 1 | 0 2 | 0 4 | 0 8 | 0 16 | 0 32 | 0 64 | 0 128 | 0 256 | 3 512 | 0 1024 | 0 2048 | 9 4096 | 14 8192 | 27 16384 | 67 32768 |@@ 1464 65536 |@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 32396 131072 | 0 SWND(bytes) 10.175.96.92 80 value ------------- Distribution ------------- count 16384 | 0 32768 |@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 17067 65536 | 0 Here we have a puzzle. We can see that the receiver's advertised window is in the 32768-65535 range, while the amount of unacknowledged data in the pipe is largely in the 65536-131071 range. What's going on here? Surely in a case like this we should see zero-window events, since the amount of data in the pipe regularly exceeds the window size of the receiver. We can see that we don't see any zero-window events since the SWND distribution displays no 0 values - it stays within the 32768-65535 range. The explanation is straightforward enough. TCP Window scaling is in operation for this connection - the Window Scale TCP option is used on connection setup to allow a connection to advertise (and have advertised to it) a window greater than 65536 bytes. In this case the scaling shift is 1, so this explains why the SWND values are clustered in the 32768-65535 range rather than the 65536-131071 range - the SWND value needs to be multiplied by two since the reciever is also scaling its window by a shift factor of 1. Here's the simple script that compares BDP and SWND distributions, fixed to take account of window scaling. #!/usr/sbin/dtrace -s #pragma D option quiet tcp:::send / (args[4]-tcp_flags & (TH_SYN|TH_RST|TH_FIN)) == 0 / { @bdp["BDP(bytes)", args[2]-ip_daddr, args[4]-tcp_sport] = quantize(args[3]-tcps_snxt - args[3]-tcps_suna); } tcp:::receive / (args[4]-tcp_flags & (TH_SYN|TH_RST|TH_FIN)) == 0 / { @swnd["SWND(bytes)", args[2]-ip_saddr, args[4]-tcp_dport] = quantize((args[4]-tcp_window)*(1 tcps_snd_ws)); } And here's the fixed output. # dtrace -s tcp_tput_scaled.d ^C BDP(bytes) 10.175.96.92 80 value ------------- Distribution ------------- count -1 | 0 0 | 39 1 | 0 2 | 0 4 | 0 8 | 0 16 | 0 32 | 0 64 | 0 128 | 0 256 | 3 512 | 0 1024 | 0 2048 | 4 4096 | 9 8192 | 22 16384 | 37 32768 |@ 99 65536 |@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 3858 131072 | 0 SWND(bytes) 10.175.96.92 80 value ------------- Distribution ------------- count 512 | 0 1024 | 1 2048 | 0 4096 | 2 8192 | 4 16384 | 7 32768 | 14 65536 |@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 1956 131072 | 0

  • How to keep a window from overlapping into another workspace?

    - by user1477
    It's annoying to me how if a window is even a couple pixels off the right edge of my screen, when I switch to that right workspace, the system thinks that the window is there. The unity launcher bar gets hidden because of it and switching to that window keeps you on the current workspace where you can't even see the window cause it's only a couple pixels. KDE seems to do this much better where when you switch to another workspace, the window just isn't there. But well I don't want KDE. Any way of getting that same behavior without the switch?
