9800 torch Touch Screen and Trackpad problem

Our application adds buttons only on devices that support the touch screen.

The reason why we do this is because if you have a selected item in a list field and press the getSelectedIndex returns the correct index on a touchscreen.

Add this button on a trackpad/trackball device would not work properly because you can't the selected list box item and then click the button. You need to scroll this button first, the getSelectedIndex in this case would be the first clue or the last index according to the place where the button.

If anyone has a solution or suggestions please post. I'll also post updates and a solution if I find one.

We had the same problem when we added a toolbar style touch the foot of some screens that contains a list field.

Our solution: vertical movement of pointer changes the selection of the list, while the horizontal movement jumps down to the toolbar, but leave the current selection in the list where it is.

May not work for your particular application, but seems to be accepted in our.

    I broke the touchscreen for my Acer V5 - 122P when the laptop has fallen. I'm trying to find out how I can have it replaced. How much should I order? The LCD works but the touch screen is not. The touch screen and LCD are separated? Alternatively, they are integrated? I'm not a computer person, so please excuse my ignorance.

    Please notify.

    Try a battery pull if you please, with the BlackBerry device powered on, remove the battery 15 seconds and then reinsert the battery to reboot the device. This will clear all hide as restarting a PC. Then try again and see if the problem persists.

    What OS are you on? On your device, type a new message MYVER and a space after to see and report please.

    On device, go to Options, device, application management is a great way to see what your applications with your use of the CPU on Smartphone. Simply drag bar greater than CPU and see what happens. Also touch the CPU menu to see other time variables. I discovered that an application has been eroding CPU cycles on my own

    remember the ESC key to close most applications, with the exception of GPS and some chat clients. other applications must use the menu and then exit or close. The key furthest to the right is a key to the House and does not close on its own apps, but will put an end to the calls.

    If the above does not work then maybe in running a new OS is in order.

    Manual device OS upgrade instructions:

    1. start by searching for your operator and the system operating file that you want to use.

    2. make a backup of your device first, using Desktop Manager > backup. Close at the end Office Manager and disconnect it from BlackBerry. Get DM here http://us.blackberry.com/apps-software/desktop/

    6 remove the internet connection for PC and reboot the PC.

    7. plug the BlackBerry and double-click on "Loader.exe." It is located in the same place as the above vendor.xml file was in.

  • Samsung series 5 ultra touch screen tactile intermittent problems

    Hello

    Windows 8 is already installed when I bought the computer. Now sometimes when I boot it the touch screen does not work. The computer seems to think that this isn't a touchscreen, even in the PC info it says that there is no button or a pen. When I restart is always seems to fix the problem and then to the PC info, it says full touch support. I have to restart it almost every time I turn on the touch screen to get.
    Any ideas?
    Thank you

    The problem is probably Fast Startsup, faster PC boots, but all drivers do not always load but they will when you restart.

    Disable Quick start, your system will take more time to start, but it should solve your problem of dual-boot.

    Go to control panel > hardware and sound > Power Options, click on choose what the power buttons do, under stop settings, uncheck quick start if there is a check mark in it.  When you perform a cold start it will slow down the startup and touchscreen should take effect, but as I said, the start-up will take a little longer.

  • Satellite L650-1EQ - black screen and overheating problems

    Hello

    I have a problem with my laptop Satellite L650-1EQ.
    A few days ago my laptop was overheated quite often.
    I would like to start playing a video game and the computer could actually turn off after 10 minutes of playing it.

    I realized that this was getting serious so I stopped using my computer to play games and I decided that I need to clean it. However, I was looking for online on how to clean up my computer and then my screen turns white!

    I didn't know what happened and was very scared.
    I turned off the computer.

    The next day I turned on the computer to see if it was good, and the screen was black however the laptop power light comes on and I hear the vents work.

    I turned on the computer and tried to start it again, and the computer started fine.
    The image appeared and the problems disappeared.
    But I knew that something bad was about to come so I took the laptop computer repair technician.

    I told her what happened.
    He has used the vacuum to "clean" the dust of the computer and told me to go back if the computer kept a overheating.

    I restarted the computer again when I came home, and after an hour and a half the computer screen turns white but I don't think that it overheated. : s

    I tried to start the computer and the screen is black, no picture, the only light on is the power one and I hear the vents work. I tried of transformed market but now it just stays as if it were now.

    I tried on another computer for solutions such as the battery and pressing the power button for 2 minutes and other things, but nothing has worked. I don't know what to do so I decided to create a thread to get answers: s

    Please help me, thank you!

    Hello

    This does not sound very good boyfriend. I'm afraid that there could be some sort of dysfunction material Mr. something like the problems of graphics card or motherboard issue.

    You can try plugging the external monitor to the laptop just to see if something would be visible on 2nd screen.
    But if nothing will appear on the 2nd monitor, I think that the chip of the graphics card died :(

    Of course, this is just my personal opinion and a laptop computer technician must check the laptop to know what part of the laptop could be faulty.

    Of course, I know what you mean about how things are. Many things change in one form or another, but the basics of troubleshooting are fairly constant. Eliminate the possibilities and drill down to the cause.

  • Separate the touch screen and mouse entries?

    The concept was to allow me to run the procedure step by step videos, scan emails and follow the tides on the secondary touch screen while playing my games on the main screen. What I see is that the touch input screen seems to be married to the coordinates of the main screen.

    Is there a way to allow multiple entries in Win7? A mouse and a touch screen running on two screens simultaneously and independently?

    Thanks in advance :) JKLauderdale

    Good so I tried this out.  If you touch the screen of the Surface to scroll through everything that is open about it, he doesn't move the cursor of the mouse at all.  The arrow of the mouse pointer disappears from view, but as soon as you touch the mouse again, it's still there at the original location on the touchscreen (no) external.

    But touch the other program moves the focus (the other program you touched becomes 'active' program), then to continue typing my response here for example, I had to click once again.

    My Dell has had some problems (patially due to age), so a buddy of mine and I put a new hard drive in it and then installed windows XP Pro.  Installation went great, but now that it's installed, I can not get the screen resoultion to change and I can't connect to the internet.  I feel like with the internet, can I have a driver problem.  I know that the internet works, I'm on it with the laptop right now.  Any suggestions?

    ????  I'm not sure I understand your question. You download the drivers to a place, you will find them, as the office. If you want to put them on a USB stick, copy the files downloaded to the key and take it to the computer target. Copy the files on the computer desktop. Double-click on a file and it will unpack the installation routine starts. Follow the installation wizard. Reset when said to repeat as needed until all the drivers, etc are installed. Subsequently, you can delete the downloaded files from Dell (from installation .exe). MS - MVP - Elephant Boy computers - don't panic!

  • Start white screen and other problems

    I don't know what exactly caused this do. I turned on my computer as usual, but instead of start normally, the computer showed the tutorial screen that you see when you start your computer for the first time.

More of this, I am unable to access or change the settings for my PC, create new folders, etc. (the drop down just 'empty' bed) or pin programs to my taskbar. My desktop items also have this box little pop up next to them when I hover over them.
    I started my computer in safe mode, but the problem still persists.

    Brilliant Hello,

    Thank you for the update on the issue.

    According to the result of the scan SFC that he managed to find some damaged files, but could not fix some of them, it means that there is a corruption with your system files. To go further and to repair system files, so I suggest you run the DISM commands and see the are able to repair system files.

    Maintenance of the images of deployment and management (DISM) installs, uninstalls, configures, and updates features and CBS packages in Standard Windows 8 Embedded images (standard 8) offline and offline Windows Preinstallation Environment (Windows PE) 4.0 images. The commands and options that are available for servicing an image depending on whether the image is offline or online. All controls operate on a standard 8 offline image. Subsets of commands are available for the maintenance of an operating system.

    I suggest you run the commands in elevated command prompt and control below if this can help.

    • Press Windows key and X at the same time.
    • Choose line (Admin) command on the shortcut menu.
    • In the command prompt, type the following command and press ENTER:

    DISM / Online/Cleanup-Image /ScanHealth.

    This command is used to check if an image is repairable. Scan the image to check corruption. This operation may take several minutes.

    DISM / Online/Cleanup-Image /RestoreHealth

    This command is used to repair an image.

    Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.
