  • Lock Windows keyboard and mouse but still display screen normally

    - by Stephen Lacy
    I'm using windows 7, I have a dual monitor display. It displays important information related to the business, I'd rather that random users that walk in can't just walk over to it and start using the computer with the same access rights as the user the monitoring software is running as. What I would like is if any time someone presses a button on the keyboard including alt-ctrl-delete all that would appear is a dialog asking for a password. Then I can click cancel and it will return to showing the data I want displayed. ClearLock doesn't work I tried it btw

  • Hide a 2nd Monitor from a Programs Print Screen

    - by jasondavis
    I run 2 monitors on a PC that also runs a program for the Freelancing site Elance.com. The program they provide, takes screenshots and uploads them to my account for a client to see at different intervals. My goal is to make the screenshot that the program takes and uploads, to somehow only take a shot of my "Main" or "Defualt" monitor and ignore my 2nd monitor. The main reason is my 2nd monitor generally has private data that I do not displayed to the world on a website. Does anyone know if there is any kind of program or trick I can use that will make it appear that I have 1 monitor when a Screenshot is taken? I am not sure how the program does it and how that works as I am a web developer and not a C++ or any kind of low level programmer. If the Elance program simply runs the same function that is called when a PrintScreen key is pressed on a keyboard, then I am thinking it might be possible to maybe trick that into only the default desktop? Any ideas or help would be appreciated, thank you

  • Using external monitor and screen resolution?

    - by Johnydep
    it might sound very basic question but i need some help. I have lenovo Ideapad y560p which offers a maximum resolution of 1366px x 768px. Now i am planning to buy an external monitor, and i short listed some FULL HD resolution monitors, but it is my understanding that even with FULL HD, i would only achieve the best resolution my laptop supports. Is it true? And also if this is the case, should i really go for an HD monitor or settle down with a lower resolution version? 2ndly, is there any way to increase resolution with simple upgrade? or it is not possible without voiding the warranty??

  • Generate random coordinates from area outside of a rectangle?

    - by Rockmaninoff
    Hi all, I'm working on a simple tutorial, and I'd like to randomly generate the positions of the red and green boxes in the accompanying images anywhere inside the dark gray area, but not in the white area. Are there any particularly elegant algorithms to do this? There are some hackish ideas I have that are really simple (continue to generate while the coordinates are not outside the inside rectangle, etc.), but I was wondering if anyone had come up with some neat solutions. Thanks for any help!

  • [iPhone] Play video not in full screen mode

    - by Kyo
    Hello, First, excuse my english :) I've read on apple developer website that video playback provides by the framework supports only full screen mode. I will need to develop an application where video can be played in reduce screen mode. I've see that Orange TV make something which looks like what i need to do. http://img218.imageshack.us/img218/1228/tvplayerorange.jpg The application is available on app store but you need to have a subscription to test this application. Whatever, to resume it, we can see video (tv stream video) in a reduce mode and if we click on the screen it switch to a full screen mode. So my question, what i want to do is possible (Orange TV made it) but i wonder the difficulty to make it. It seems that I have to make a video player. If it take a bunch of time, I tkink I will use Media Player Framework of iPhone even isn't the optimal solution for me. Feel free to ask me more details ;) Thank you for your answers.

  • How to make PuTTY X11 forwarding work in a screen session?

    - by Alex Howell
    I'm using PuTTY with X11 forwarding enabled, using Xming as my X server on Windows 7. When I SSH to a Linux host, X11 forwarding works fine. If I start a "screen" screen manager session, it still works fine. If I disconnect from the screen session, then later resume in a different PuTTY window using "screen -rd", X11 forwarding doesn't work any more - I get an error: xterm X connection to localhost:11.0 broken (explicit kill or server shutdown). This seems to be because $DISPLAY is different in each PuTTY SSH session (localhost:11.0 in the first session, then localhost:12.0 in the next, and so on). If I manually set $DISPLAY to localhost:12.0 in the screen session, X11 forwarding works again. Is there a way to automatically set $DISPLAY in the screen session, each time it's resumed, so that it always matches the parent PuTTY session's?

  • Android multiple screen sizes and density problems

    - by Ben Mc
    I'm having a real problem with my drawables that I just can't seem to figure out. The problem is this: There are screen sizes at approximately 320x480, 480x800, 480x854 Then there are most commonly densities at 1.0 (160) and 1.5 (240) Now, on a Droid, the screen size is 480x800 and the density is reporting using DisplayMetrics as 1.5 On the G1, it's 320x480 and reporting back at a density of 1.0 BUT tablet devices are reporting back at 480x800 with a density of 1.0 (160) So, I'm going mad because I can put 320x480 images in the drawables-mdpi folder and 480x800 images in the drawables-hdpi folder, but on Tablet computers, no matter what it's not resizing up anything to a full screen. Any help would be greatly appreciated. I just want all of my 320x480 images to scale up regardless of the device.

  • zsh behaves weird in screen

    - by Nils Riedemann
    Hi there, I have zsh set up as my default shell. It works fine as long as i am not within a screen. When i start screen it looks as if some dotfiles are not loaded. For example my $PATH isn't set correctly and some directories are missing. I'm not quite sure where to start looking. Since all is fine, as long as i'm not in a screen. My dotfiles can be viewed on github. I also use oh-my-zsh — as you will notice.

  • Rendering splash screen on the iPhone using Open GL ES

    - by Rich
    Hi, I want to render a splash screen on the iPhone whilst using an Open GL view. The iPhone screen as we know is 320x480, which is not a power of 2. Before I enter into the world of chopping the texture up and rendering sub parts, or embedding the screen on another texture page I was wondering if there was another way? Is it possible to overlay another view that I could render to using CoreGraphics functions? Or is it possible to render to a Open GL surface using Core Graphics functions. What would you recommend? Cheers Rich

  • Opening a new screen from xml file text.

    - by Clozecall
    Hey all I'm looking to edit my app so that when a text within an xml file is selected, a new window opens. I've found various ways of making a new screen open via a class, but I need it done from a xml file. My program as a tablayout, and here is some of the stuff displayed within my first tab: <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> android:id="@+id/ScrollView01" android:layout_height="wrap_content" android:layout_width="fill_parent" <TextView android:textColor="#FFFFFF" android:text="First Header here" android:textStyle="bold" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <TextView android:textColor="#FFFFFF" android:text="First body text here" android:layout_width="fill_parent" android:layout_height="wrap_content" /> So basically I need it so that when a text is selected, a new screen pops up. As said the reason this specifically has to be done in xml is because this is all apart of a tab layout, It would be great if the next within each tab could open a a new screen. Thanks.

  • How to make a rectangle on screen invisible to screen capture ?

    - by Kesarion
    How can I create a rectangle on the screen that is invisible to any sort of screen capture(printscreen or aplications) ? By create a rectangle on screen I mean something like this: #include <Windows.h> #include <iostream> void drawRect(){ HDC screenDC = ::GetDC(0); ::Rectangle(screenDC, 200, 200, 300, 300); ::ReleaseDC(0, screenDC); } int main(void){ char c; std::cin >> c; if (c == 'd') drawRect(); std::cin >> c; return 0; } I'm using Visual Studio 2010 on Windows XP

  • "Aero snap"-animation not working correctly on the right side of the screen [closed]

    - by Niklas
    When using the "aero snap"-feature on the right side of screen the animation doesn't fill up the complete screen height, Only if the mouse pointer is at the very top of the right side of screen. Otherwise the animation box moves vertically as the mouse is moved along the edge of the screen, this does not happen on the other sides of the screen. I thought about submitting a bug but the bug program advised me to ask here first.

  • Isometric - precise screen coordinates to isometric

    - by Rawrz
    I'm trying to translate mouse coords to precise isometric coords (I can already find the tile the mouse is over, but I want it to be more precise). I've tried several different methods but I seem to keep falling short. For drawing I use: batch.draw( texture, (y * tileWidth / 2) + (x * tileWidth / 2), (x * tileHeight / 2) - (y * tileHeight / 2)) This is what I currently use for figuring out a tile position: float xt = x + camPosition.x - (ScreenWidth/2) ; float yt = (ScreenHeight) - y + camPosition.y - (ScreenHeight/2); int tileY = Math.round((((xt) / tileWidth) - ((yt) / tileHeight))); int tileX = Math.round((((xt) / tileWidth) + ((yt) / tileHeight))- 1); I'm just wondering how I could update these to allow for more precise coordinates, instead of tile only. EDIT: Following what ccxvii said below, and removing the -1 from tileX, the object follows my mouse just like I had wanted. Just going to re-examine the math and figure out if that change will result in other messes =o

  • Why does my Ubuntu freeze in the middle of something with a blank screen?

    - by mohamed
    I am facing a serious problem as my Dell Optiplex 745 loaded with Ubuntu 12.04 32bit freezes with a blank screen no mouse cursor no keyboard activity in many occasions. Sometimes when I open firefox, or software center, I really can't tell what the main problem is, but what i am certain about is it i have to do a hard reset to reboot. I tried to use a live-cd to boot but it did the same, tried the recovery console but couldn't find a way to fix from there (I am a new user) suspected a hardware problem but windows runs flawlessly so I believe its something related to ubuntu. Specs: Intel Celeron D 3.06 GHZ 3.0 GB ram Intel built in graphics Q965 1 TB HDD Bios Phoenex 2.6.4 Please help I really love ubuntu and I don't want to go back to windows!

  • Raycasting mouse coordinates to rotated object?

    - by SPL
    I am trying to cast a ray from my mouse to a plane at a specified position with a known width and length and height. I know that you can use the NDC (Normalized Device Coordinates) to cast ray but I don't know how can I detect if the ray actually hit the plane and when it did. The plane is translated -100 on the Y and rotated 60 on the X then translated again -100. Can anyone please give me a good tutorial on this? For a complete noob! I am almost new to matrix and vector transformations.

  • Creating a curved mesh on inside of sphere based on texture image coordinates

    - by user5025
    In Blender, I have created a sphere with a panoramic texture on the inside. I have also manually created a plane mesh (curved to match the size of the sphere) that sits on the inside wall where I can draw a different texture. This is great, but I really want to reduce the manual labor, and do some of this work in a script -- like having a variable for the panoramic image, and coordinates of the area in the photograph that I want to replace with a new mesh. The hardest part of doing this is going to be creating a curved mesh in code that can sit on the inside wall of a sphere. Can anyone point me in the right direction?

  • New EFI Laptop: After restart, Ubuntu boots to black screen?

    - by Henson S
    So, I've got this new laptop (Acer Aspire 5560 15") that's doing a funny thing.. If I cold booth the machine, everything is great! I see the grub menu, and Ubuntu 12.04 loads just fine. If I reboot within Ubuntu, I see the BIOS screen, but then nothing. No grub menu, no hard drive activity except for just a blip. I noticed that when installing Ubuntu this time, I had to create an EFI boot partition -- something I'm not used to. And I'm guessing that it has something to do with the issue. Could be totally wrong. Any ideas?

  • Android how to get opengl 3D coordinates in ontouch event

    - by Sandy
    I created a cube in opengl and it rotates in ontouch event. To to this I created a CustomSurfaceView as follows public class CustomSurfaceView extends GLSurfaceView { @Override public boolean onTouchEvent(MotionEvent e) { float x = e.getX() float y = e.getY(); } } Here x and y are screen coordinates. How can I get 3D coordinated from this? I have already looked gluProject and NeHe. But I dont know how to implement this in my project, it shows that there is no GLdouble,GLfloat class.
