How to start a subdiagram when he meets a specific condition

I have a file of commands (epoc.bat)

I use Labview to call this batch file. The batch file will be run a task on the windows command prompt, and it will show my value of sensor material permanently (at the frequency of 128Hz) in a text file on the disc. Please note that the batch file creates the empty text se file and then writes the values in this text file.

The problem is that the batch file needs time to initialize the material (a hundred milliseconds) before it prints the first value of the probe. My job is to determine when the first sample is printed, in order to launch my right to events after that the first value of the probe is printed.

I put my question in the VI of attached file. Also this photo below which describes clearly.  I put all the events in the correct order in a sequence of dish.

How can I determine when the first sample is printed. I think that there are 2 steps: first of all check if if the text file is available and then checking the size of the file? How can I make this work. Then and especially, how can I build a condition to run the following image?

This technique works... I just tested it...

    Hi Anna,.

    Click the icon (top left of your screen) Apple > System Preferences > users and groups.

    Then, by default, the "Password" button is selected on the top. Click on the button "Login Items".

    Here you can add items, folders, applications, network even locations which will be launched during its connection.

    Find Skype in your Applications and add and it will start automatically when you start your Mac.

    (I have OSX Lion, if you have something else, it might be a little different, but I think the general idea is the same

    Good luck!

  • How to start a task when the other ends

    I want to run multiple scripts in the order (in Windows 7 Professional) and each have a tenure when the previous one ends. Is there a way to tell the Scheduler to do this? There are a variety of different types of (Korn Shell scripts running under Cygwin, R, BACK lot), and each of them produces results that are used in the following script. Different types of scripts, I don't think I can combine them into a single script.

    I do this every night, to develop a weather-based forecast for a hands-on experience. There are a lot of calculation and a time limited, and I do also simplified as possible, so I can't just schedule the scripts independently, separated far enough out so that they would never overlap. I couldn't get Cron to work in Cygwin, so I'm using the Windows Task Scheduler.  So far I can get all one script to run at any time I want, I just can't understand how to link the start one at the end of another.

    You can put several actions in any task to Task Scheduler.  You will use the trigger 'on an event"for what you need.

    The best advice on TS is Task Scheduler Overview - MSTechNet.

  • How to start viClient & Login when Windows starts

    Actually it's maybe a stupid question but for some less techie or low-level administrators, this can be useful in some situations.

    Especially if we need help from other admins, but do not want to release our passwords.

    I have a job I have run 2 x viClient for the PRD VMware vCenter VDI VIew VMware vCenter respectively.

    -Click the shortcut of viClient

    -Choose the vCenter in menu drop-down (or type it in)

    -Enter the ID user & PW (I normally use Windows logon credentials)

    Is it possible to automatically open a session:

    1. start the viClient for the PRD VMware vCenter when workstations Win7 boot?

    2. run the viClient at the sight of VMware vCenter when workstations Win7 boot?

    3. start the viClient for the VirtualCenter of VMware RDP via a shortcut or a batch file?

    4. start the viClient for the VMware View VirtualCenter via a shortcut or a batch file?

    Try to change the properties of the shortcut to

    "C:\Program Files (x 86) \VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe" s u user_name Pei Secret Server

    or

    "C:\Program Files (x 86) \VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe" s server - passthroughAuth

    If you use Windows authentication.

    Don't have not tried, but if you want the client autostart, it might work if you add shortcuts to the startup folder.

  • How to start the program before windows 7 user logon

    I already know how to start a program when a user logs on to Windows 7. * (Not easy to find, but once you know the trick, it's simple as pie: place a shortcut in C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup). So don't answer that. I already know that.

    But my question is this:

    How can I get the same program to launch * before * the users logon? I want the program start when Windows restarts.

    This program does not require the user's privileges - does not open the files, etc., except access to (of course) its location in C:\Program Files (x 86) / folder.

    (What, you may ask? I would like to launch a program of Wake-on-LAN to send a "magic packet" to a computer on the local subnet to sleep. Asleep computer happens to host some of the shared data).

    If you want to start until the user opens a session, you will have to start as a service.

    This is the boot sequence for the main registry keys, starting immediately after reading bootmgr and ending with the program shortcut entries in the two startup folders.

    1 HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\BootExecute. This may include instructions to schedule chkdsk runs, but not the user programs.

    2 services start ensuites, followed by the keys of registry RunServicesOnce and RunServices (if present)

    3. the user then connects to the system

    4 HKLM Winlogon, Userinit. This indicates that the program C:\WINDOWS\system32\userinit.exe, and the entry ends with a comma. Other programs can be started from this key by adding and separated by a comma.

    5 HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell. This must contain an entry, explorer.exe.

    6. program entered into these key 2 registry for all USERS start following:

    HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and \RunOnce

    7. program entered into these 2 registry for the CURRENT USER key start following:

    HKCU\Software\Microsoft\Windows\CurrentVersion\Run and \RunOnce

    8. programs in startup of all records users and current user are started last of all.

    Important as antivirus and firewall programs begin early in the sequence as Services. The icons that appear in the Notification area (at the bottom right of the screen) is just their user interfaces, i.e. options and preferences.

    The additional location of 32-bit applications on a 64-bit computer is HKLM\SOFTWARE\Wow6432Node and HKCU.

  • How can I configure windows update in order to start the procedure, when I connect to the school network?

    OT:help configuration of Windows Update.

    I use windows 8, now my problem is that I have to enter a user_name and password each time you start the browser, if you close the browser, or open another browser, you must enter user password again once you use a wifi or lab computers. Now when I connect to wifi, my browser instantly request name username-password but windows update is not so. I tried this a few times, only once named windows update displays dialong box asking username and password and it takes hours to do.

    How can I configure windows update already if start update already when I connect to the school network.

    Wifi authentication which traverse the browser means that you still need to open a browser and a connection that first, before any other programs can access the network.

  • How to start a timer in labview, when a signal crosses a threshold of voltage

    Hello

    Please could someone help to find a way to start a timer when an event occurs? (like when a signal crosses a threshold of voltage)

    Thus, I would ask that help me cope with the following question:

    I'm acquiring a signal from an acquisition of data and comparing it with a certain threshold value. Once the voltage of the signal crosses this value, a timer should start and will continue until 30 seconds, IF the signal value PERSISTS beyond the threshold. The timer must be set back to zero if the voltage of the signal goes back the threshold before a period of 30 seconds.

    Thanks in advance for your support,

    Bill

    Hi Bill,

    What version of LabVIEW are you using?  If you are in 2009, you can actually save the .png to your computer file and just drag it into the block diagram of a white VI.  Also attached is the VI even recorded in LV 8.2 (the feedback node has been replaced with a shift during the downconversion register).

  • SUBJECT VERY ESSENTIAL... HOW TO START A DATABASE PROJECT

    Hello everyone,

    I actually followed several courses in Oracle, in particular, in DBA. With the fact that all my classes are hands-on classes, but I really want to start something for me. I want to see me do something. For example, an oracle database for a school. I know it's a very big project; but I want to create a small demo of the project for a school database.

    My problem is I don't know where to start! Should I create the tables first through SQL. create points of view; Enter some data demonstration; Then go to build forms; and build reports? This is how it works?

    Please give me an advice in simple and clear words.

    Thank you very much.

    How to start a database project is no different from any other software development project. There is a basic software development lifecycle SDLC (or life).

    The first thing to do is to determine the objectives of the project. You know what must the project and what requirements must be completed.

    If you do not know that... so how do you know what to develop, how to test that and when to stop development?

    There are tons of books on the subject. There are many views and opinions, and SDLC methodologies - but your project does not have a dollar of multi-million one, you can afford to keep it simple and easy.

    The basic software engineering life cycle has the following steps.

    User specification. This article describes the basic problem (in a perspective of business or user) that needs to be addressed. For example the school needs a student registration system...

    Specification of functional requirements. These are crucial because they determine the goal of the project posts. The final solution s/w is checked against this and every listed function checked to see if the s/w addresses. Functional specifications are independent of the technology. No project, no architecture and no coding considerations at this stage. Instead, the functions are described that the system must support. For example "add new student" will be such a function. "a transfer student" another. Each function will be described in detail (from the perspective of the company) exactly what the company needs to do and have to perform with success this business function.

    Requirement technical specifications. This translates the functional specification in the data sheet. These technical specifications is what will be used to develop the system and that developers will use. It should contain the data, specification of database model, specifications of language, standards, architecture, interfaces and management controls and so on — all the workings of the proposed solution.

    Development and test phase. This is where the database is created, a software written, created test harness, etc.. This is typically an iterative phase (develop service abctest abc, defdevelop, test the function def, function etc.).

    Deployment phase. In this phase the system for the use of production - and often goes hand in hand with final test and acceptance (by ensuring that the delivered system meets the requirements of functional specifications).

    In a Word, this is the essence of a software lifecycle. There may be many differences on that. Agile design and development is a relatively new approach (but always contains the basic ingredients of above). It was JAD (joint application development) which became popular in the 1990s. There is DSDM (Dynamic Systems Development method) and others.

    But don't be too preoccupied by these--as sucks it that you understand the basis of the life cycle of software engineering and know how to create the action plan you need before that start whacking away at the keyboard creating tables and writing code.

  • Response of local folders looks like the answer to the discussion group. No signature or formatting options. How can I change the local folders meets regularly?

    Please see image attached. Responses from the eyes of local folders as responses to the discussion groups. No signature or formatting options. How can I change the local folders meets regularly, as they are in the Inbox?

    I don't think that the format of replies to the messages in the local folders are linked with focus groups or to individual account settings. As local folders can contain messages between several accounts or identities, it is more likely that formatting uses the setting of the account or identity appearing in the: field when you reply.

    This is how I think it should work. How this works in practice may be different.

    Hello

    Does anyone know how to start to use the remote that came with my makeup P750 114.
    When I press on simple volume keys + / doesn't seem to work.
    I have the batteries in it but do not know if I have to activate something on the laptop itself to start using the feature.

    Hello

    A remote control that is included with some models allows you to perofom certain functions.
    Using the remote control, you can
    -Navigate and control the media center window
    -Check the video or live tv display
    -Place the computer in and out of fashion "Eve".

    There is a button on the remote control.
    It begins or ends the OS. The functions of this button as your computer's power button. By default, the "sleep mode" is equivalent to powering down of the State of your laptop. to change this click Start-> Control Panel-> system and security-> power options.
    You will find options; do nothing, sleep, hibernate, shut down.

  • Satellite L500-14Z starts to beep when it reaches 10% of battery

    Greetings,

    As I installed the sound card driver on my laptop, it always starts to beep when it reaches 10% battery in every 10 seconds. It is not a voice of Windows, but I tried to look for the sound controls and even the BIOS to disable this thing. It may be useful in some cases, but I really want to get rid of him or to use only if the screen is off and I do not see the level of battery charge.

    Overall, the question is, how do I disable or control the sound signal after the 10% battery level without uninstall the Realtek audio driver?

    Yours Sincerely,

    Fifty

    Hello

    You can disable it in:
    Start > Control Panel > Sound
