serial in WPF instead of command line does not work

Need help, solve a problem of serial communication. I have a serial communication prog which works fine when the command line, but behaves sporatically when run from a WPF form. It's like I need to put something in the program with the serial port. It worked for a while without problem and works reliably from the command line. Is there something that I can put to open the serial port and let it free?

Hi Paul,.

  • Windows 7 Defrag from command line does not work

    We are running Windows 7 in a virtualized environment. When you run windows defrag hourly use of the command line, it does not work. The order that I will execute as administrator is

    C:\Windows\System32>defrag/c

    Microsoft Disk Defragmenter
    Copyright (c) 2007 Microsoft Corp.

    It displays the above message and leaves back to the command prompt. However if I run the defrag C: command it does not. Defragmentation from the GUI works so as long as both drives (C: and system reserved) are selected and when I click on defragment drives, works very well.

    I am concerned about defrag from the Task Scheduler with the command ' defrag/c' (self programmed to help set up the calendar... from Disk Defragmenter) does not work and the system never gets defragmented automatically.

    This only happens with some of the windows virtual machine 7 we have.

    There are no entries in the event log that point to defragmentation (using the Task Scheduler). Anything can happen on the ideas?

    OK, if the phone has been implemented using the o2 network and you want to use it with another carrier, you need to get o2 to unlock your phone.

  • After upgrading to LR 6.2 G (grid mode) command shortcut does not work in the library module. How to fix?

    After upgrading to LR 6.2 G (grid mode) command shortcut does not work in the library module. It works well to return to the grid when in the develop module. The problem was not resolved with LR 6.2.1.

    PS: Being a urser LR since 2008 I hate the new import dialog so I have stopped using the program and will do so until the classic dialogue is back. Or it won't and I should start looking for alternatives?

    One number of others have experienced this problem - please add your vote and details of this bug report in the Adobe official feedback forum: Lightroom: keyboard shortcut 'G' does not not in the library module.

    A few others have reported that restart the computer immediately after resetting preferences seems to fix the problem.  Also note that you can use the ESC key to exit the view library Loupe return to the display of the grid.

  • system files and command prompt does not work

    For the last two weeks, I'm having a nightmare. I disabled system restore and when I turned it on again every thing had stoped working (microsoft word and works procedssor), the user account micxrosoft help and support).

    I tried using command prompt, but it does not work properly. When I typed in the shadow of the list he has the right to copy, my name and disturbing without clichés present in this system.  When I go to system restore I just get ablank screen white. If I go into system the control panel says that my C drive is followed.

    I don't know what else to do Windows XP came with the perchase of my little computer. I only am not computer savvy very please check all instructions fool proof. Please HELP, as all I want for Christmas is saystem restoration. Thank you very much

    Please provide additional information on your system:
    What is your system brand and model?
    What is your Version of XP and the Service Pack?
    Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..
    The afflicted system has a CD/DVD drive work?
    You have a true bootable XP installation CD (it is not the same as any recovery CD provided with your system)?
    It seems that your system has or has had a malware infection.
    What is the issue that you are experiencing that you think that the system restore will be remedied (or you are just convenient)?  System Restore is not a time machine...
    You should be able to get your system restore calendar works again quite easily, but who will not only relieve your system of malware.
    Don't forget to fix the problem and the difficulty not only the symptom of the problem.
    If you disabled the system restore and he turned his back, which removes all points existing restoration (this is how it is supposed to work).
    I run a few scans of such malicious software indicated below, then work on all the remaining issues.
    Sometimes malicious will afflict your system restore to prevent you to find and remove malware.  It would much rather you trick into thinking that you need to repair or reinstall your XP when it is not necessary.  System Restore is sometimes so afflicted, you need to reinstall the system restore (you don't have to reinstall XP - just reinstall the system restore).
    No matter what you use for protection against malware, I do so and then only begin to solve any problems:
    Download, install, update and do a full scan with these free malware detection programs can solve any problems:
    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
    It can be uninstalled later if you wish.
    Restart your system and resolve outstanding issues.
    If your system restore calendar is always to show just a blank white screen, do the following:
    The scans using own it may also be necessary to re-register some dll (or you can do this part first, but you still have to do the scans).
    Re-record the dll is correct, even if they do not need re-registration.  You can also re-register the dll before the scans that can solve the problem, but the scans are always recommended.
    Click Start, run, and in the box enter orders following one at a time.  Click the OK button to execute each command one at a time:
    regsvr32 jscript
    regsvr32 vbscript
    regsvr32 /i mshtml
    The last order for mshtml load the DLL but can also contain a harmless warning depending on your environment.
    Check your system restore calendar now.

    Do, or do not. There is no test.

  • Highlight the line does not work after dynamic refresh

    Hello


    Request Express 4.2.1.00.08


    Hoping someone can help with this. I have a report (list of loans for a person) who gets refreshed dynamically when the account number is changed. The loan id column is a link when you click fires a dynamic action that uses JavaScript to highlight the current line

    $('.highlight-row').removeClass ('point culminating-row');

    $(this.triggeringElement) .parent () .parent () .children () .addClass ('point culminating-row');

    It works fine first time around, but if the loans area is updated the javascript does not work anymore and the current line is not highlighted.

    Thank you


    Neal



    Hello

    What is the scope of the event?

    It must be dynamic.

    You can create a new DA the event which is:

  • Simple straight line does not work

    Hello

    I leaned on AS3 code to:

    http://www.republicofcode.com/Tutorials/Flash/as3drawvectors/

    Near the top of this page, the author gives this very minimal code to draw

    a red line. The code is below:

    var my_shape:Shape = new Shape();
    addChild (my_shape);

    my_shape. Graphics.LineStyle (1, 0xFF0000, 1);
    my_shape. Graphics.MoveTo (50, 50);
    my_shape. Graphics.LineTo (100, 50);

    I pasted the code above in the Panel (frame 1) actions in

    a new flash document and I get 4 errors

    rather than a straight red.

    Anyone know why this code does not work?

    Thank you

    Jim

    Hi Jim, check this box:

    var my_shape:Shape = new Shape();

    my_shape. Graphics.LineStyle(1,0xFF0000);
    my_shape. Graphics.MoveTo (10, 20);
    my_shape. Graphics.LineTo (stage.stageWidth - 40, stage.stageHeight - 180);
    my_shape. Graphics.endFill ();
    addChild (my_shape);

    It's a little funny to you so that can see the potential to make shapes with actionscript

    stage.stageWidth - this is the width of your paper.

    stage.stageHeight is the height

    Good luck

  • BlackBerry App line does not work for me on 10.3.1.1179

    Hello
    Is - it still works?
    I ask because the link does not work for me on 10.3.1.1179

    I installed the nod as the link says without problems, then I downloaded and install the link on my phone. But it automatically closes when I press on it, even with Snapchat & Spotify.
    Anyone got it works on a Q10?

    MOD Edit: Edited post to reflect the new title of the topic

    Not all android applications work on BB10. I know that Snapchat does not work. Snapchat does not work, nor will they let someone else create an app to work. They don't like the BB users and do not plan to support them. Others I have not used personally so I can't say with certainty the current state for these applications.

  • 'command R' does not work, I can not restore the OS

    iMac11, 2

    4 GB at 1333 MHz RAM

    Macintosh HD 999,35 GB

    Unfortunately, I installed "Guardian of Mac". Although I have not activated my iMac has become very slow. Someone told me that I could solve the problem by getting the old version of the Time Machine OS. I tried several times, but the 'command + R' didn't work. He starts trying to connect somewhere (globe spinning on the screen) and after about 15 min, the Apple logo appears on the screen and stays there forever and nothing happens. He was supposed to appear a window of the utility of choice, isn't it? Can you help me, please?

    Thanks in advance.

    If your profile is correct and that your Mac running 10.6.5 then there not a Partition recovery which is required for the command + R to work.

  • Why the command/tab does not work in the new discourse during a presentation

    Why the command/tab doesn't work with Keynote 6.6.1 during a presentation.  I can't get out (smoothly and professionally) presentation for applications that run in the background, then return smoothly.  Slows down my presentation, seems unprofessional.  This key combination worked very well until I used the new version of Keynote.

    We have no problem with the service application switcher using Yosemite and Keynote 6.6.1 on any of our client systems, or there is no record of anyone having this problem on the discussions.

    This sounds like a problem of systems;

    • what amount of RAM is installed
    • What is the amount of free space on the boot volume
    • have you antivirus, security and cleaning of installed applications
    • emptied the Recycle Bin
    • is the clear office of files and folders
  • command prompt does not work well. He is unable to run the commands like 'help, tree, ipconfig, netstat', n many more

    the command prompt in my system has attracted some problem. A few months ago, it was all fine. BT now its disturbing. do not run the commands of other than "exit".

    even in the bar of tasks run these commands will not be executed.
