• Why can't I control my subfolders? (And how many files am I missing?)

  I'm trying everything under the Sun to import my last set of pictures in a subfolder in my collection. Import-> copy, import-> move and import-> add all seem to place the photos in a new folder in the root directory of my catalog, although the photos end up in the right place in the system of files on my hard drive. When I try to move them in Lightroom, it says that they are already there.

  If I try to sync my folders, get me into trouble as all my changes and metadata get deleted, because he seems to think that all my pictures are new. Lightroom seems to have a schizophrenic response to this:

  

  All right, so he wants to delete about 18000 photos and add 20000, removing my metadata and changes. Large. Reading from another thread, it seems that this isn't the way to go, and I can just tell Lightroom to find my missing photos:

  

  So, who's Lightroom?

  How can I get my folders to synchronize, but not to lose all my work?

  After a lot of frustration and searching, it seems as if my probem was that my file user on my old Macbook was "blair" (tiny b) and my new Macbook uses a more formal: Blair: with a capital b. I learned that Lightroom is case-sensitive, while my Mac OS is not. This is why when Lightroom asks MacOS to give it an image data, it appears despite the gap of the case. However, when he looks to see if the pictures are missing, they all appear absent because Lightroom resists less than "blair" and "Blair" is the same person. Somehow my catalog remind the old structure of directory (in lowercase) and confused trying to import new photos into the new structure.

  He seemed to have solved my problem as follows:

  • Leaving Lightroom. Created a new folder in/Users/Blair called "bananas".
  • Moved all the content of "/ users/Blair/images" to "/ users/Blair/bananas."
  • Starting Lightroom. All the photos and records were presented as being absent. Right clicked on ' Users/blair/images' and 'location of folder update... "said and pointed to" / users/Blair/bananas. " All photos and relevant changes / metadata was found.
  • Leaving Lightroom. All left/Users/Blair/Bananas to/Users/Blair/Pictures
  • Started Lightroom, photos and files, missing once again, "location of folder update... "once again and he did to" / users/Blair/images ".

  It wasn't how I wanted to spend half of my Saturday, but it works now.

• Why can't I control the 'name' on my Yahoo email?

  I have two Yahoo e-mail accounts. One of them plays very well and as you when I send a message from him, it displays the name I gave you ('Bob W') as the sender when it is received by the recipient. This gives the floor VAC ' t #1.

  The other account has the problem. The problem is that when I send an email from him, he shows only the name of 'Yahoo!' or 'Y!' as being the sender when it is received by the recipient. Call this VAC ' t #2.   In addition, the "Yahoo!" is their corporate logo in purple "BOLD" and is not something that I typed in any area of settings.

  It is worth noting that I checked all settings account and I see no difference in settings between these two accounts.

  How can I get acc '#2 to perform as VAC t' t #1?

  Thank you for any help or advice.

• How to read and display a my a miccrontroller (MCB1700) on labview signal connected via a port on a PXI machine CAN

  How to read and display a my a miccrontroller (MCB1700) on labview signal connected via a port on a machine PXI CAN?

  I tried using a DAQ Assistant, but the port is not included as one of the physical channels supported, even if all his drivers are up to date.

  Help, please...

  Thank you.

  If you can read it in MAX, then you should be able to run the NI CAN example.

  Help-> find examples

  Find the CAN and watch CAN Receive.vi.

  Basically, set up the network, open the object, read in a loop close object when it is done.

  If you have any questions about the example, go ahead and post your vi and we can work from there.

• Can I remotely from a computer that does not have control with LabVIEW?

  Hi, I have a PC at work that has LabVIEW (LV) installed, and I order several machines using a GPIB/USB interface. I would like to be able to control them remotely, at home, so I can start new experiences without having to enter in my lab. However, my PC at home isn't LV what are my options to achieve this?

  The most obvious solution is to use a software that allows me to remotely control the PC of my work, and then do that. However, it would be nice if there is an easy way to interface directly with LV. For example, something where he would create the VI as a Web page, and then I could see it in my browser to home or something. Is there something like this?

  What are my options to control everything from home, without LV on my PC at home?

  If "at work" is a reasonable society, there will be a firewall and it would be difficult to do anything without their approval. Connections to the internal network from external random places are usually blocked for good reasons. Talk to your first COMPUTER service.

  Assuming that you can connect to the remote computer, you can start reading here. Be aware that several modern browser (e.g. Chrome) is no longer support or allow NPAPI plugins, then your choice of browser style are limited.

  A better choice is direct on the remote control. This allows you to fully control the LabVIEW application, start it even if it is not active, loading/saving files, etc.

  I generally use Chrome remote desktop. I can connect to one of my computers from anywhere, even if both computers are located on networks private behind a NAT or firewall. Works great!

• With the help of modulated signal pulse width (square wave) to control when a signal is enabled or disable

  With the help of modulated signal pulse width (square wave) to control when a signal is enabled or disable

  Hello all

  I am using a modulated signal to labview created pulse width (square wave) to control when a signal is activated or not.

  Here is my logic and a concrete example:
  (1) the wave source signal is continuous
  (2) use a PWM (square wave) created in labview to control when the signal is enabled or disabled
  (3) if the PWM (amplitude) signal is superior to 0 play signal PWM is not greater than 0 do not play signal.

  I use actually this to the sequence step / pulse several distinct magnetic coils using my audio card (which has several channels of audio output), I have a signal in labview played constantly.  As to compare it to the PWM (square wave) which controls whether or not the signal is played on each separate channel.  That way I can control which coil is on and offshore and in what order they are activated.

  I couldn't find an edge detection for a square wave created in labview, so I tried the limits, but it doesn't seem to work unless I change the phase manually and it only goes 1-1.  I'm just trying to compare the PWM (edges of the square wave) already created by labview / play a signal if the pulse is greater than 0 and it shuts off the signal, if she is less than 0.

  Should I do this another way

  TIA

• I can't Omega PX4200 pressure transducers where I can get a reading of Labview

  Hello

  I am a new user of LabVIEW, and I currently try to wire in a 4-20mA Omega PX4200 pressure sensor in an NI USB-6009 Data Acquisition device. I have sources of power like a P SOLA SDN 5-24-100, and I use a 3-wire system. I have the black wire going to SOLA a +, the ground wire to the GND on the NI USB-6009 case and the white wire going to the AI0. Currently, I am unable to generate a significant signal either in solution of measurement and Automation Explorer or LABVIEW Signal Express 2010.

  If anyone has an idea on what I'm doing wrong, just reply to this topic.

  Thank you

  Dev

  The USB-6009 measure the voltage.  The pressure transducer is a current signal.  You must add a kind of conditioning of signals.  At a minimum, you must use a resistor to the terminals so that you can convert the signal 4-20 mA, the transducer is a tension.  To convert a signal of 20 MA in 10V, you would need a 500 Ohm resistor.

• VisualAnalog control with labview

  Hi all

  We bought an AD9643 that came with an FPGA based FIFO capture Board of Analog Devices, since they are just called VisualAnalog software to read the data and the control of the Board of CDA. Can I manage control this software under Labview?

  We just need to make easy control as start, stop and get the data.

  I tried the ActiveX method, but when I try to insert the ActiveX object, may not find all related objects.

  Hey Martin,

  I'm not particularly familiar with similar Visual but LabVIEW is usually good enough to communicate with third-party software. You said you tried to make calls through ActiveX (which was also my first try) and that doesn't seem to work. Below, I have included a link to an article that should be helpful when trying to interface with other software using LabVIEW.

• LabView signal generation

  Hi guys,.

  I have big problem with my signal generator and have no idea where can be a problem. I did a LabView program to make the signal that I am the phone my NI PCI-6221 card thanks to the DAQ Assistant. My program is:

  

  The Panel fromt with indicated generated signal is:

  

  But my problem is with the evolution of my signal parameters in the build process. For example when I change the weather, so the square exhibitor will take more time, I see on my osciloscope some rest of the previous signal. So the final singal (osciloscope) looks like this:

  

  (Sorry for the hand-painted painting)

  If I stop the program and start it again the new signal with new parametrs is built perfectly. So I think that the PCI 6221 once I have changed some settings is not throw all the data in the buffer (at least I think). For the DAQ Assistant, I use continuous sample with 800 k samples per second. With this mode (continuous sample) I get this remain on new signal signal. When I tried to use N samples mode, it seems to work fine, but generation time is really slow, medium, once per second and I need to use my card for data rading too so it's out of the question. I tried to program this PCI card manually write function (instad of DAQ Assistant) too, but then I ger hard signal which is really not so smooth from DAQ Assistant. I evn tried to change the number of samples each time when I change some parameters, but it did not work. I'm sure I'm doing something wrong, but after two days of looking for a solution, I'm out of ideas. So question is where can be the problem and how to change signal parametrs without obtaining this rest of signals, means how to clear buffer completely when I changed the signal. I use LabViw 8.5 but it is possible to use any newer version too, if you think that old version of labview can be the problem.

  OK I found the solution, it was impossible to use the normal function of Express DAQmx. After that I changed slightly this explicit function block, everything was fine. It was necessary to recalibrate the output of my card every time when I changed one of my settings. So whenever I changed something, I stopped my bit of any communication outupts and reinicializate of my PCI card.
