• Divide a line into several points

  I see that I can use SDO_LRS. SPLIT_GEOM_SEGMENT to divide a line into one only point (and get 2 lines resulting).
  
  However, someone at - it an idea how can I split a line, at several points, in several segments? I need to do for the number of lines, so a function or procedure would be nice as appropriate.
  
  Thank you

  Sorry for pasting quick and dirty, was a minimum on time and problems with my dev env.

  Perhaps still not the best outline but hoping there more explanaition should be ok.

• Multitouch touch several points of confusion

  I'm currently implementing several points of contact for the first time.  I tested on a Samsung Galaxy Tab 2 7.0; If I device USB debugging, AIR indicates that the device supports 2 points of contact and touch events are supported.

  The app I'm trying is in its infancy, so there's not much going on right now. I have two SimpleButtons that I am putting in place so that the user can press both at the same time, but I can't make it work right. If I hold the first button and then press the second button, the first button is pressed and the second button does not recognize a press (the SimpleButton doesn't change even its origins to the depressed state). If I want the second button, and then press the first button, the first button does nothing, and the second button is released (in my code and visually).

  public function enableButtons (): void {}

  Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;

  trace ("supportsTouchEvents:" + Multitouch.supportsTouchEvents);

  Button1.addEventListener (TouchEvent.TOUCH_BEGIN, onHoldButton, false, 0, true);

  Button2.addEventListener (TouchEvent.TOUCH_BEGIN, onHoldButton, false, 0, true);

  }

  private void onHoldButton(event:TouchEvent):void {}

  trace ("the" + event.target.name);

  var button: SimpleButton = event.currentTarget as SimpleButton;

  button.removeEventListener (TouchEvent.TOUCH_BEGIN, onHoldButton);

  button.addEventListener (TouchEvent.TOUCH_END, onReleaseButton, false, 0, true);

  button.addEventListener (TouchEvent.TOUCH_OUT, onReleaseButton, false, 0, true);

  }

  private void onReleaseButton(event:TouchEvent):void {}

  trace ("BUTTON of UNLOCK" + event.target.name);

  var button: SimpleButton = event.currentTarget as SimpleButton;

  button.addEventListener (TouchEvent.TOUCH_BEGIN, onHoldButton, false, 0, true);

  button.removeEventListener (TouchEvent.TOUCH_END, onReleaseButton);

  button.removeEventListener (TouchEvent.TOUCH_OUT, onReleaseButton);

  }

  I'm doing something wrong here? Do SimpleButtons support multitouch?

  Can't seem to edit my post, so here's the short of it based on your findings.

  Here's the answer: SimpleButton does NOT support Multitouch.

  You can mark this or your own answer as being correct.
  

• Pop-up window with several point

  Hello
  
  I want to create a pop with several point window when I click on the button.
  I want to insert the value into the table using this pop up window.
  
  
  How can I do that.
  
  
  
  
  Thank you

  Hello

  1. create a normal page with multiple elements and process page to insert the value in the table. (Assume that it comes from page 10)
  Edit this page
  Switch to the attribute to display tab.
  Under page template, select popup

  2. now, suppose you have a button on the Page 9 and when you click on this button, page 10 show popup in a pop-up window.
  Edit this button
  Go to the tab URL redirection
  Under target, select URL
  in the target URL text box enter

• How to select several points of movement Tracker?

  I have a trajectory of Tracker with a lot of points. I can slide individually, and I can Shift + click to select more than one. But is there an easy way to select all the points in a given region? Or, best of all, all the points that follow a given time?

  I'm trying to drag all the points that follow a discontinuity in the path, to the difficulty of the discontinuity.

  Don't know what you're trying to do here. These 'points' are just keyframes and can be mass selected in the timeline panel and then you can change the values it by rubbing the digital displays. This will adjust them compared to the base value. If you need anything else, then you must adjust them one at a time, although you can find tools like KeyTweak and others found on AEScripts useful...

• Cannot listen to an audio track of several registered through the recording of the cycle... ?

  I'm a new logic/Mac user, so I think I'm missing something obvious.

  I use Logic Pro X I used the cycle recording recording a few songs - but changed the following setting:

  -went to folder, duplication of Audio recordings, create titles selected and Mute under record Cycle

  -J' recorded audio takes 4-5, which was all placed in the new circuits controlled by a single potentiometer

  -When I listen to these songs at the same time, I only heard one of them at a time. If I cut one of the tracks, they all get muted. If I solo, they all get to have.

  Why don't I hear a track at a time? I want to double to the top of my voice recording, but seem not to be able to...?

  Please help, thanks!

  -Mike

  You know a little more sense, to understand what is happening.

  The "short": answer

  • In logic, a track (the way horizontal track that records your regions) and a channel strip (which is responsible for the delivery of audio) are two separate components.
  • You can create several tracks which are all assigned to the same channel strip.
  • All of these buttons Mute , Solo buttons, sliders to Volume and Pan buttons are technically identical, a representation of the coontrols of this single Channel Strip. So pressing a button Mute or Solo allows all other buttons on the pieces.
  • This is the program installation you created with the recordings option overlapping 'create tracks.
  • You must create new tracks (assigned to their own Channel Strip) or reassign these tracks and copy regions.
  • In your case, select records that overlap "create a folder to" and then choose "unpack new tracks" in the Comp Menu.

  You might get the idea that there is some learning/reading to do to be able to use logic, regardless of what you do.

  Hope that helps

• Data storage of the optical spectrum for several points and recalling a specific

  Hi, I'm working on an installation of measurement of the optical spectrum automated for a summer project, I have been using labview for about a week now and have had bases for stage motor control, but I have problems with the data management...

  I'm looking to store data such as those acquired with an optical spectrum for several XY points Analyzer and recall the optical spectrum for a specified point? Currently, I am looking at writing to the file of measure and reading of the measures such as the options file, but I'm not sure how to name each piece and the data and to recall them correctly. Are there examples where this has been done? any help will be greatly appreciated.

  I use a connect Yokogawa AQ6370 via ethernet, LabVIEW drivers are provided for this, but I can't find the screws provided here is

• Several points of access Cisco Aironet 1131AG and same SSID?

  We have several Cisco Aironet 1131AG, all wired devices on a switch (2560) Cisco L2 which is connected to the L3 switch (3550). We have assigned a VLAN for access point to the L3 switch which acts as a vtp Server (L2 switch is vtp client). All the ap will have a static ip address and all will have the same SSID and no security, and they will use several channels (e.g. 1,6,11).  They will work in 3 floors for a roaming wireless client. We not using any wireless controller.

  So my question is this: how to configure the same APs-all with a different ip address, can we use L3 switch to create the dhcp server to access points VLAN (pool for guests) and the rest of the static ip address for the ap? One of the ap can be WDS and on the same radius server local time with users without Cisco Secure ACS or similar controller or I did not understand this very well :-). I followed the guide http://www.cisco.com/en/US/docs/wireless/access_point/12.3_2_JA/configuration/guide/s32roamg.html for WDS where Abu Cisco ACS part is a problem, so I can use the same ap as a Local authenticator as a guide http://www.cisco.com/en/US/docs/wireless/access_point/12.3_4_JA/configuration/guide/s34local.html#wp1035723.

  Thank you very much...

  Well, just so you know, WDS, and local RADIUS authentication is necessary only if you use authentication on your wireless connection.  You say that you do not plan to use security, so it's not necessary.  However, I highly recommend at least using a simple WPA2-PSK to lock your connection, otherwise you might end up giving free Internet access at best and at worst you could give access to the computers and corporate servers.  If you want to reuse a 802. 1 x or WPA authentication method, then Yes, you can use an AP as RADIUS and to improve WDS Server authenticated to roaming, but this is much more limited than the use of a Cisco ACS.

  As for your other questions, Yes, your APs can all be configured the same except for at least three settings: IP address, hostname, and channel.  Configure your static IP addresses on the interface of the PA BVI1.  Do not place it on the Radio or Ethernet interfaces, because if one of these interfaces goes down, you lose the ability to configure the AP, so it's best to use the BVI1 interface.

  And Yes, configure a DHCP scope for your customers on your L3 switch is good design, or you can also use your DHCP server on a different subnet by using the command of support-ip address on the interface of L3.  I hope this helps!  Let me know if you need help to set all this up.

  Merry Christmas!

• Warp track missing stabilizer points...

  Stabilize a bunch of clips using warp stabilizer and some bit of reason points are not visible on a random selection of them. Have on, off a bunch of times, without a bit of luck. Everyone experienced before?

  Three things need to be checked if you want to see the WS follow points:

  1. the effect in the effect controls should be highlighted

  2. the track points see the verified on Advanced sub

  3. control of the layer must be on. Click on the Tools tab: display-> control of the view layer, or click the path to mask and of shape toggle visibility button

• How can I do a summation of a table summarizing several points once, leaving me with another table?

  Hello, I tried to find a way to do the summation of a table, the sum of 19 points at a time, leaving me with another table.  I feel like this has a simple solution, but I'm not sure how.

  Thank you.

  A time loop that contains the subset of the table can do.

It provides information in real time to a patient when walking from their foot position, random target (points Exchange with each step) and a reference point (constant).  At present, data from three points are grouped in the same plot on the graph XY.  In the graphics property, when I change the color for field 0, every color change.  I tried to connect the XY graph in table built above, but a cut wire it occurs (connected 2 groups with different content).

  Any help would be great!  Thank you

  Thank you.  I tried to change the plots in properties, but it did not work.

  Here's what you can do with very minor changes. It is basically the same as in my previous example.

  

• Several points of access WAP300N just stop working

  I have 3 WAP300Ns in my office, all with the same SID.  They will work for several days, then stop working - will not respond to the ping, etc.  I do not think that all fail at the same time, but seems it tends to be in a group.  (I know they are all 3 down when I can't get Wifi)  Turn off and turn on again gets working them again.  All have the latest firmware.  I tried different frequencies but doesn't seem to help. Very frustrating.  Any suggestions?

  Lets see what are the results of a disabling WPS.

• Tracking of Multiple Point in Blackberry Maps

  Hi all

  I wonder if it is possible to use the webworks geolocation API to plot multiple points on a Blackberry or a Google map. Has anyone tried this yet? Are there references that you could give me to kick off development?

  Thank you!

  Yes it is possible. You ask just the API to update location and add the coordinate on the map. Just be careful with Google maps, as it can break WebWorks events.
