  Hello

  I put t know if the touchpad software includes this option.
  You should check this in the touchpad options.

  You can find it in:
  Control Panel-> mouse-> tab advanced-> button Advanced settings

  But in my case, this option does not exist.

• Simulate the entry

  Hello

  To check my software, I want to simulate some signals on the entrance of the simulated NIDAQmx Council. Is this possible?

  I created the jury simulated in NI MAX, but I know not how to simulate the signal on the inputs and run my software (in C language) in order to acquire the data.

  Thank you

  Theinput signal of the simulated device is built-in, you can't change it. It is better to write your own piece of code that simulate the signal.

• Trying to simulate the device USB-6366 (without success)

  I read through the tutorials DAQmx and MAX about the simulation of the device, but I can't yet find a way to effectively simulate the acquisition and generation of a signal using a device USB-OR-6366.

  I am a (given at the entrance of this VI) signal using DAQmx Write and then use DAQmx Read to read the signal captured from the internal memory of the card (which has a buffer of 32 MS). To do this, I created a task with DAQmx I feed in the writing block.

  I know that the approach is most likely wrong, but I can't understand not just how to do this in a simple way and documentation of NOR is anything but simple. All I want is to

  (a) test using 2 digital inputs to capture this signal by the device and then read what she has gained from its internal buffer

  (b) send the same signal to 2 digital outputs the signal output again.

  See you soon

  Yes! the simulation is designed to allow you to write a program and check that it works theoretically even if you do not have the material physically available. It has no interface programming to influence on the what the reading functions will return simulated data. And write the function has no notable effect anywhere, working as a receiver of data in nirvana. It is always useful because you can test software without getting all kinds of errors on the non existing hardware access attempt, but it has its limits, of course. However, a programming interface for manipulating that which and how the data are simulated, while it would be a very interesting feature, is almost certainly to complicated not only to implement but also to use.

• Avast! Writes to the SSD much antivirus software during scan

  Hi guys,.

  I have installed avast! Antivirus on my Mac, do not protect my Mac specifically, but to keep it to pass on the Windows malware to other computers or on my Windows partition. When the full analysis of the system, I notice that he reads a lot of data in the player (that I know), but it saves up to 40 GB of data in the SSD at the end of the analysis! I know writing excessively on the SSD can shorten their life (although I tried to calculate its expected service life using my daily writing, and I should have at least another 10 years of use, which is more than enough).

  My point being, why is avast! write on the disk so during a scan? Is it caused by a heuristic analysis or something? I don't want to put unnecessary pressure on my SSD, even though I know that Apple SSD are generally pretty durable.

  Thank you.

  Note: Please don't give me a conference on the installation of antivirus software on Mac - I know that this is not strictly necessary but I explain why I use it at the beginning of my post.

  Your windows contacts can take care of themselves. He has no need of you to your Mac protecting wear.

  Your Mac is already well protected without that avast garbage making it unstable.

• Satellite A660 - question of recovery of the system and Windows software

  Hi all

  I recently bought a new Toshiba laptop and created a set of disks for backup use Toshiba Recovery media creator.
  Now, this laptop is proved to be defective and was exchanged by another.
  There was a slight difference in the software, what the faulty version was preloaded Office 2010 starter and the new Office 2007 trial 60 busy days.

  As I have already created backup discs of the defective model (i.e. same spec/model number) can just recover the system using the device backup discs?

  The reason why I want to do is that I prefer the Office 2010 Starter version (as opposed to the trial version). Software recovery disks that you create on this computer in particular connected serial number is or can I use them on the new machine to replace the identical specifications?

  Thank you

  Generally you can use it if the two laptops have the same part number (model number PAxxxx).

  Before that, you create an original DVD for the machine, you now have. If something goes wrong, you can use the original disc.

• Simulate the sine wave using LabVIEW FPGA with NOR-myRIO and display in real time

  Hello

  I'm relatively new to LabVIEW FPGA. I am trying to test (and later apply) controllers high speed on myRIO.

  At this point, I'm trying to simulate the sine wave from 1 to 10 kHz using Sinewave generator VI express. I also intend to display the sine wave on the time real (RT) using FIFO. However, I had a bit of trouble to understaing various synchronization parameters.

  1. how to encode information about the sampling frequency generating sine wave? (The side FPGA vi requires only the frequency of the signal and possibly phase and does not rate update lines)

  2. how to estimate the number of items in a FIFO? (that is, the relationship between the rate of updates to loop (RT), the signal frequency, sampling frequency and the number of items in the FIFO)

  It would be great if we could share a very simple program (side host and target) that did something similar.

  Thank you

  MILIN

  Milot,

  I think the problem is the type of data in your FIFO. Your FIFO is configured to use a data type of I16. The problem is the number, it displays only ever will be-1, 0 or 1. To resolve this problem, you must send the sine wave as a fixed point data and convert it to a double on the side of the RT. This should significantly improve your resolution.

• Use the toggle button to simulate the Ctrl key now

  Hello

  I saw someone asked something very similar before, but nobody seemed to know the solution.

  I was wondering if it is possible to use a toggle button to simulate the CTRL key now, the idea being that the user could then zoom in on a rectangle of their choice on a field without having to press the button themselves. I know that you can use the FakeKeystroke function to simulate support that the key however is possible that it may be held?

  Thank you

  I forgot one thing. You must handle the case when you have a real EVENT_DOUBLE_CLICK. In this case, you don't want to reset the keyboardState. Here's the modified code.

  char oldKeyState [256] = {0};
  
  char newKeyState [256] = {0};
  
  int isFakeDouble = 0;
  
  Zoom CVICALLBACK int (int, int int event, control panel,
  
  		void * callbackData, int eventData1, int eventData2)
  
  {
  
  	HWND hwnd;
  
  	toggleButton int = 0;
  
  	switch (event)
  
  	{
  
  		case EVENT_LEFT_CLICK:
  get the current state of the keyboard
  
  			GetKeyboardState (oldKeyState);
  
  			get the State of the toggle button
  
  			GetCtrlVal (panelHandle, PANEL_TOGGLEBUTTON, & toggleButton);
  If (ToggleButton)
  
  			{
  
  				create the new copy of the keystate
  
  				memcpy (newKeyState, oldKeyState, 1);
  Active control key.
  
  				newKeyState [VK_CONTROL] = 128;
  
  				SetKeyboardState (newKeyState);
  generate left mouse button events that will be holding the CTRL active
  
  				SetActiveCtrl (panelHandle, PANEL_GRAPH);
  
  				GetPanelAttribute (panelHandle, ATTR_SYSTEM_WINDOW_HANDLE, (intptr_t *) &hwnd);)
  
  				isFakeDouble = 1;
  
  				SendMessage (hwnd, WM_LBUTTONDOWN, 0, 0);
  
  				isFakeDouble = 0;
  
  			}
  break;

• No option to simulate the peripheral cRIO after installing Labview and RT/FPGA Modules of downloads (lack of driver support?)

  Hi guys -.

  Basically, I need to simulate a cRIO device without yet having equipment on-site, like this:

  How to simulate the FPGA hardware target using with LabVIEW Project Explorer

  Instead, I only get the options presented in the attachment "Add Target Options.jpg.  I guess it's because of missing drivers, which I assume is due to an error that I made during a recent new LV installation installation went like this: I downloaded (not diskettes) and installed the following (in this order, the latest versions all around):

  (1) LabView development system

  (2) real-time module

  (3) FPGA module

  (4) NEITHER-RIO (previous installation-by-installation)

  (5) DAQmx

  At the end of (1) and (2), I got the screen shown in the second attachment ("Drivers Installer Message.jpg"), but could not able to recognize the folder "device drivers OR" (I also downloaded), or one of its subfolders.

  According to me, I'm missing an obvious option to load the necessary drivers after installation, but can't seem to find reference to it in the forums.  Could someone give me a little help in the right direction?

  Thanks a lot and have a nice day.

  
  

• Simulate the structure of the event in the LabVIEW base?

  I have a basic version of LabVIEW (v8.6) who doesn't have the structure of the event. I found it was quite embarrassing monitor the status of several controls (action after clicking a control depends on the State of the other control (s)). Especially if I want to add another function (control), the effort exponentially increase with the current number controls

  I had an idea to simulate the structure of the event using "shift register. First, I will provide all the values for the controls in a cluster. Then I'll put the cluster in a while loop and compare the value of the cluster to its previous value (xor the registry change). If the result of the comparison is false (none of the control is changed), the program moves to the next iteration. If the XOR result is true (one of the control has changed), then the program goes into code (it will pass what control has changed and the entire cluster) event management. So for each change of control, we can write an independent code to process the event. After processing of the event, the event was allowed.

  Here are some of my ugly code currently used to monitor multiple controls. And I think rewriting using above idea so there is less chance a hiden bug.

  Comments, suggestions?

  I'm not quite sure what I'm looking for on your photo of your block diagram because it seems that only the lower quarter right in your code.  I would do the following to detect a change in a cluster without the structure of the event control:

  

  The basic package include the notifications than us?  You can put your "event management" in another thread by this method:

  

  The advantage here is your main loop of the program is not "bogged down" every time that a change in your cluster held.  It also allows to separate the code so that it is cleaner.

  Hope that helps!
