• Column data reading according to the number of lines

  Hi guys,.

  I am currently stuck on the problem of recovering the data from my database (MS Access) according to the number of lines, he has at any time (without having to know how many lines there will be during the programming of this part).

  First, I show how my program works. I'm working on an automated food, order and after the customer has chosen his power, system information such as the name of the food, quantity and price of the food will be written to the MS Access database table. (for example table name "Orderingtable" in MS Access) For my case, 1 order of food will occupy 1 line of the database table. In other words, as part of the same, if he orders 3 different foods, 3 rows will be filled in my database table.

  I would then get the part number of 'Quantity' for each order of the database and summarize the amount finally to count the total number of orders in the table of database at any time. This addition of result will be then shown on the Panel before informing the customer how many orders waiting's just prior to his order. In this case, it can get out if he wants to, if the number of orders is too big for its waiting time.

  However, I do not know how many lines my 'Orderingtable' will be 'Orderingtable' because both accumulate lines and data lines until being command to remove. Therefore, I cannot predict how many lines I program the party totals the number of quantity for each line.

  Is it possible that I can get the part of the 'quantity' without having to know the number of rows in the database so that I can count the total number of pending orders just by adding up the value of the quantity for each line?

  I do not wish to "code" my program by limiting the tables of database for us are going to say, only 50 lines at any time.

  Attached below, this is how my database table "Orderingtable" looks at, which will be used to extract the 'Quantity' column so that it can count the total number of orders and be shown/shown on the front panel of my Labview program.

  I hope that you are able to help me!

  Thank you so much in advance.

  See you soon,.

  You can also use the SUM function:

  SELECT SUM (Quantity) OF the order WHERE Queue_No = %d

  And no need of an "Order By" clause, if you add just the quantities.

• Reading from the sensor to LabView via rs232 or Subvi problem

  I'm quite new to LabView and not too experienced with instrument control so I was wondering if someone could help me to solve my problem?

  Currently, I'm using LabView 2011 and I'm trying to read pressure DualGauge of Pfeiffer (TPG 262) pressure sensor and display the readings of two pressure on LabView.  However, when I run my program, the pressure readings are not displayed - what is displayed are default 0.00 if same mBar pressure reading a reading of the display of the DualGauge probe.  To connect the sensor, I use a RS232 cable and have managed to find the device on my device manager, so I don't think that the connection is the problem (I've also seen the port appears in the Device Manager, when I connected the sensor via RS232 and USB in my computer).  I also use Subvi Pfeiffer in my code, and I suspect that the problem may be in there.

  Attached is my code and here are links to the manual of the DualGauge and the driver of the software LabView of Pfeiffer

  Double manual gauge - p. 23 and 68 are probably the only things related to the RS232 connection.

  Any help is very appreciated!

  You have not tested really do anything. Devices and MAX Manager displays only the com port that you added to the computer. It does nothing to verify that an instrument is truly connected. You might have the wrong settings of com or the wrong type of cable serial (null-modem is required). I suggest that you start with program such as hyperterminal, PuTTY or MAX and try something simple. It seems that you will receive an acknowledgement returned by the instrument when a correct command is received. Make sure that this simple step that happens.

• Read power meter in LabVIEW via RS-232/RS-485

  Hello!

  I have a power meter, an advanced WM14 DIN power Analyzer. I want to display different values, Kwh, WILL, etc. Kvar, the meter in the graphs in labview. I have just a basic knowledge of Modbus RTU and with RS-232 connection. But I don't know how to make it work with labview. To my counter, I plugged a converter Moxa TCC-100 (see attachments) RS - 485 to RS-232, given that my electricity meter works only with RS-485.

  The converter, I have an adapter usb to RS - 232 (see attachment) to COM3 on my PC.

  Perhaps the easiest way would have been the connection directly http://sine.ni.com/nips/cds/view/p/lang/sv/nid/12845 . But I have not bought!

  So now you know the configuration of the connection, drivers for the usb adapter is installed and also VISA drivers. I found no good examples explaining how you can do with programs and data sending and reciving.

  I have google around and discovered that you use read/write VISA blocks, and that there is a library, Modbus, you could use. I installed the library, but I don't know how to connect with my electricity meter.

  I have a communication protocol to my electricity meter, but I don't know how to use it.

  I'm a little stuck and don't really know where to start. But my understanding of modbus, such things should be easy to do, so I think that's not too difficult to learn.

  Is there anyone who could explain how these work thing or if there is something I could read or see?

• All read old version data file in Labview 8.6 (waveform playback of file.vi)

  Hi, I have a big problem on the use of file.vi in LV8.6 reading waveform to play *.wmf files that were generated LV7.1 program.

  He often appears a message windows, refer to the attached picture file, because I use LV8.6 program to read a considerable number of such files,

  I can't afford all these windows message in my program, please tell me how to get rid of this message.

  Thank you very much

  Hello

  The type of waveform data is in LabVIEW 8.6 differs from the version 7.1, so this conversion is required. This knowledge base article solves the same error: Read Waveform files from old Versions of LabVIEW .

  To prevent the message from appearing, add silentDatalogConvert = true to the LabVIEW.ini file. It is located in the National Instruments\LabVIE 8.6 folder. I hope this helps!

• you want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. A

  I want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. After that, I want to arduino to send out necessary via a serial port to labVIEW which should be read using visa read and store in a chain. While I am able to write or read both individually, I can't do it consecutively. I used advanced read and write vi for checking my code, but nothing is helping. The wrong bed 'time delay before execution. " Please let me know where I can go wrong. Also is it possible to write code for hx711 using labVIEW

  1. you need not "\n" on your orders println().  This command adds an end of line character already in the message.

  2. you get the error because you have a loop around your reading.  After the first reading (well technically, the second because of you add an extra line end character), there is nothing left in the port.  As a result, you will get the timeout.

  3. you should really consider using a Structure of the event.  This way you just don't write and read when you press the Write button and you can also use the structure of the event to make the loop to stop.  I also go up to close the port inside the stop-> value Change event.

  

• Failed to retrieve the DIAdem DataFinder research data, using data-finder toolkit LabVIEW 2009

  I am facing problem to retrieve the DIAdem Datafinder data.

  At first, I developed this project in LabVIEW 2010. But because of a problem that I met in LabVIEW 2010, I thougth to work on the project in LabVIEW 2009.

  Then, I reused the project that I created using LV 2010 using option economy for the previous version.

  When I tried to retrieve the data from the tiara using data finder toolkit. I got a 305505 warning. Please see the attached message of Warninig.

  But I have not seen this warning while I was working in LabVIEW 2010 and also, I was able to get the data from the tiara.

  Please suggest me a way to solve this problem.

  Hi Nanda,
  There is a bug when using the SDK use in combination with DataFinder Toolkit 2009.
  This bug is already fixed in LabVIEW 2010 and use SDK 2010. But as you said there is another question in LabVIEW 2010, forcing you to LV 2009.
  I suggest you use LabVIEW 2009 with use SDK 2009 and DataFinder Toolkit 2009 and instead to use the "Waveform.vi results" to read the search results, I would recommend to use the screw storage. I spread your example VI and it attached to this message. You will still see the dialog box to search for "lvStorage.dll" but it will automatically disappear and the VI works anyway because in this case LabVIEW will find the dll itself.
  My extended VI uses the '_openWithRoot.vi' to open a file with a different use than CT or PDM. This VI is also described in the following knowledge base article: http://zone.ni.com/devzone/cda/epd/p/id/4181
  With LabVIEW 2010 use support has been enhanced and fully integrated in the standard palette of storage screws. So in LabVIEW 2010, you can replace the "_openWithRoot.vi" with the 'Open Data Storage.vi' standard but with LabVIEW 2010, you can also use "Waveforms.vi results" to read the search results.

  I hope this helps.

  Kind regards

• Error - looking for help to recover or restore my data reading disk Windows 7

  My Windows 7 Pro machine restarts automatically while I had an open browser window (I didn't actually see it happen) but now I just see a message that says "a disk read error has occurred. Press Ctrl + Alt + Delete to restart» By pressing this key sequence does nothing. Just see a black screen with this message.

  I have booted from the CD of Installation Win 7 then went to repair. I tried to do a system restore, but no restore points could be found, so I chose the first option. No bones were listed in the list. A few diagnostic tests was performed and I looked at the details. The series of tests except the last System Volume has been altered. It says to reboot to see if that could fix the problem. Unfortunately, it does not and I still see the same black screen with the error message. BTW, as you know, I can't start in safe mode. Also restart on a Win 7 CD now is no longer gives me an option of just complete repair install. I tried to use this boot drive as one secondary drive on another machine to Win 7, but the OS tells me I need to format the disk before it can be used.

  I'm willing to put in the time to try to get the data restored on this boot drive, but don't know what I should try next. Reload the operating system completely wipe the file allocation table and make the data unrecoverable? Please notify.

  Thanks for the help everyone. I was able to restore all my files to the best of my knowledge. Just a quick overview in case others are experiencing a similar problem:

  1 SSD with Win 7 wouldn't start. Message displayed "a disk read error has occurred. Press Ctrl + Alt + Delete to restart» I restarted the machine and went into the BIOS to check that the drive was detected, which it was.

  2. started to Win 7 install DVD and select the repair option. Ran chkdsk on the drive affected with FixMbr and FixBoot, BootRec. I tried to restart after each of these executables, but he led the original disc reads the message. Along the way, the error messages I received were that the System Volume was damaged and Windows cannot recover master file table.

  3 reinstalled Win 7 on a separate startup disk (HDD) and mounted the SSD corrupted as a slave drive. Win 7 brought a dialog box to reformat the SSD drive as the data seem to be unreadable. Has rejected the format option. At this point, I am unable to browse the files on the SSD via Explorer.

  4 pitted some tools part 3 the SSD which indicated that the partition table on the disk doesn't have the hexadecimal value of appropriate endpoint.

  5 Ran chkdsk /r. Finally, some luck. This process lasted several hours and repair the files of nearly 1 million. The reader become navigable via Explorer. The directory on the disk structure has been restored and files (so far I have not found the missing files).

  What is the router of society provided separate cable from your cable modem? If so then why not just use the Netgear router instead of the provided ISP router?

  If it is a combination cable modem/router device and you want to run the Netgear router as a wireless access point then only...

  Here is a FAQ that will help you in this...

  http://www.dslreports.com/FAQ/11233

  Basically would be configured with a LAN IP in the same range as the IP address you get from the existing cable modem/router Netgear, Netgear is connected directly on the LAN cable port existing via a LAN port modem/router, Netgear DHCP server is disabled and that you configure the single wireless SSID, type of encryption (that is to say.) WPA2 is the best and do not use WEP) and a strong key. Here is an example...

  http://sdrv.Ms/LrESP6

  When you configure the Netgear I recommend that you connect to it with an Ethernet cable if you screw up the wireless and the DHCP part you can find and recover.

• I want to thank my wifi in another part of the House with an Airport Extreme. But I want to not be connected to the modem main via ethernet cable is it possible?

  I want to thank my wifi in another part of the House with an Airport Extreme. But I want to not be connected to the modem main via ethernet cable is it possible?

  I put in place already to extend the wifi of my modem still connected to the modem via ethernet cable.

  Now I want to be considered on the floor and use it to extend the wifi without ethernet cable

  The AirPort Extreme can extend only wireless signal from another router from Apple, so if you want to take the AirPort Extreme on the floor and extend wireless signal, you will need another airport connected to your modem by Ethernet cable router to produce the wireless signal that will extend the extreme on the floor.

  Another way of saying the same thing would be to say that if you want to extend wireless using a router from Apple, you'll need two of them do... because AirPort Extreme is not compatible with a third-party modem or modem/router for this purpose.

• Satellite A300D-135 - BIOS - System Configuration data read error

  Press to resume, installation

  After pressing F1 the machine starts Windows, very well, but the error message is quite irritating, while it comes with a loud BEEP

  I tried the following things so far (in that particular order):
  -Load BIOS default
  -Flashed the BIOS with the latest version of the BIOS (2.80) for this type of model
  -Reinstalled windows with HARD drive format

  All the these did not work.

  I saw the same message appearing on several places on the internet (on different laptops with a Phoenix BIOS in common), but so far I have not been able to find a working solution.

  It might me a hardware problem, but all devices (vga, soiund, lan, wifi, usb, hdd) seem to work perfectly under Windows, so this does not seem the question). Another solution that is mentioned in some forums, replace the battery. But because the phone keeps time correctly I don't think it's the case either.

  Any ideas?

  Kind regards

  Hello

  The POST (power on self-test) BIOS checks and detects errors on the motherboard.
  I think it has something to do with the hardware on the motherboard problem.
  I doubt that you can solve this if update of the BIOS and the BIOS default settings didn't change that.

  What to say; I think that the technician of the ASP should run tests to check what's wrong or what cause this I think it is question of s mobo.

  Help, please! because the "BEEP" is now getting on my nerves!

  See you soon

  Hi andrew_net82,

  It seems that the BIOS has detected an error with a certain part of material...

  Before doing something I recommend you load the default settings in the BIOS. If you are in the BIOS Setup, press the F9 key.

  If it doesn t work you need for professional assistance from an authorized service I think. Guys need to check which part of the material is defective and must be replaced.
  List of the ASP, you can find on the official website of Toshiba.

• Why the last OS update cost me gigabytes of data when you are connected directly to my computer and ISP via Itunes February 29, 2016

  Why the last OS update cost me gigabytes of data when you are connected directly to my computer and ISP via Itunes.  29 February 2016

  While it is connected to ITunes via my Dell system, I was informed of the latest OS update for my IPhone 6.  I decided that the direct connection to the internet would be the fastest way to download and install the software.  During the process I started to have some warning of our AT & T account that I approach the limit of our data plan, then in quick succession, only warnings, said I've reached the limit and then passed in the data, limit charges.  At the time it was done, I had accumulated more than 2 gigabytes of additional data charges.

  Until that point, I was very pleased with the device and confident in the ability to use Wifi and data.  Due to this incident, I became very suspicious of the camera and the huge potential for data overcharges. It is extremely disconcerting as it happened while it is directly connected to the internet using my computer at home.

  Please note that, in the episode my ISP and the computer is remained connected to the WEB with no sign of connectivity issues.

  Someone at - he had a similar experience and understand what went wrong?

  Thanks for your support,

  Jerry

  You have chosen the option of direct download, you have received a message of warning from AT & T about it yet.

• Access iCloud drive via the command line

  I wanted to write a small script to access iCloud by car via the command line, and to my surprise, this seems to be a very special place that is not displayed in /Volumes or even in my home directory is Dropbox.

  Veterinarians here know the way, if not to enlightenment, then to iCloud drive?

  Thanks in advance.

  It is actually a rather interesting problem. I did research I should have done before I came here and found that iCloud Drive is accessible here:

  ~/Library/Mobile\ Documents

  What is interesting is that the many, many interesting things found in this directory when you reveal all the files through ls - al, is that custom directories seem to appear. Even more interesting, in the Finder, select go > go to folder... and that type path and it does not recognize the path. Type ~/Library/, and then of course that's fine and see you the directory of Documents Mobile...
