Controlling the STDIN STDOUT of a legacy in LabVIEW application

I have a legacy DOS base program that runs in a command line interface in Windows.  Normal use which is a type of operator in a command, look at the result, then type in another command based on the results.  I need launch this application, KEEP IT OPEN and send/receive orders from certain TIME CMD line Interface IT IS ALWAYS OPEN.

Because I need to open this program, I can't use normal Exec.vi system that allows a single STDIN/STDOUT.

Has anyone else done this?  I heard that it is possible using PERL, but I'm doing it in native LabVIEW, if possible.

Under Linux, you can use the LabVIEW VIs hose supplied with. For Windows, you can try the OpenG Pipe library.

WARNING: Only library Pipe works for me but it is not fully debugged software, so beware when using it in a production environment.

To install the attached package you prefer using the Manager of Package of VI.

  • by using labview co-simulation, how to control the PWM market factor in multisim

    I am new to the use of Multisim with LabVIEW using co-simulation. I would like to ask if there is a PWM component in Multisim, which can have its cycle have to be controlled using LabVIEW? I have an algorithm in LabVIEW that returns the duty cycle values between 0 and 1, representing the percentage of duty cycle.

  • Cannot control the volume

    I have an Apple TV 4 (tvOS 9.2.1) with a Philips BDM4065UC 40 '' monitor (not TV) connected via HDMI. Everything works OK, except that I can't control the volume with the Apple Remote.

    In the volume control settings, I can choose between 'Auto', 'TV via IR' and 'Off '. Obviously 'Off' does not work. But not more than the other two.

    I asked Philips support if the BDM4065UC supports the HDMI-CEC, that I understand to be a sine qua non for Apple TV, and I'll make their response when I get it. However, I understand that the options 'Auto' and 'TV via IR' would not be displayed if HDMI-CEC was not taken in charge for the monitor.

    I can't form a new setting because the BDM4065UC is not a remote control to train with.

    I tried to use Apple's HDMI cable and the HDMI supplied with the BDM4065UC.

    Any thoughts?

    I'm waiting for the volume of a computer screen (if it has speakers) to be flown by the device to which it is connected. The monitor is equipped with a remote control, otherwise I think he won't have the receivers to receive a signal from one.

  • How to control the rendering of the tab character in a TXT file?

    When I browse a TXT file, the tab character is rendered in order to look a lot like 8 places. Is there a way to control the apparent number of spaces in the rendering? Yes, I know that things like

                   pre { tab-size: 4 }
    

    in CSS3 could control this number in the rendering of HTML elements, but I want a control similar to a TXT file.

    Or if you want to use CSS, this bookmarklet will insert the style rule on the page:

    javascript:var r="pre{-moz-tab-size:4;}"; var s=document.createElement("style"); s.type="text/css"; s.appendChild(document.createTextNode(r)); document.body.appendChild(s); void 0;
    

    (Note that at least for now, you must prefix-moz - on the size of tabs in Firefox.)

    Hi TheWeav, the article you mentioned is for the new phones of filed. Is your question about one of those or Firefox on your Windows XP system?

    Versions of Firefox for desktop computers do not have a brightness adjustment. You can adjust the brightness of your display using the global setting for Windows, which may include some special on your keyboard function keys or a Windows Control Panel.

    If you want only to adjust the brightness of the pages in Firefox - to moderate the white backgrounds, for example - you could try an add-on.

  • How to control the fan on Portege Z830?

    I have a Portege Z830 with BIOS version 1.7 and I am very upset by the noise of the fan.
    I was wondering if it is possible to control the fan noise, so I started to experiment with a little utility called SpeedFan. I put in place so that the fan will not turn on until the temperature of the processor exceeds a defined number. But it does not; It seems that the BIOS is ignorant these parameters.

    So my question is how can I set the fan to work my way?

    There are not many options to control the fan.

    The fan is controlled by the BIOS. The fan table that is stored in the BIOS contains information how a cooling module must operate.

    As mentioned by Liam, you can change the settings of power plant of Win 7 more battery as a way to minimize the performance of fans
    This should help a little...

  • Satellite C660D - software to control the fan speed?

    Just brought a C660D. Someone knows the software to control the fan speed?

    My laptop CPU fan always turns to 74-80% of max speed. That's a lot of noise. I tried cpucool, but it did not work.

    If does not work, the fan speed will remain at the temperature of 0 with cpu at 38 oC. But with any operation tiny, like the click of the mouse, it will change again to 74%, CPU temperature does not change.

    You are looking at it too deeply. We can't control the AppleTV himself device. Instead, you tell iTunes output its flow to the AppleTV and just play:

    Hello

    I guess that the Toshiba Power Saver has been installed on your laptop and you use this software from Toshiba.

    If you are using Win XP and that the GST is installed, then you can check the configuration of basic settings and you might find the options to control CPU, CPU processing speed and method of cooling.

    If you are using Vista, then you should check the Vista Power Options:
    Check this thread how to manage Windows Vista power management features
