X220T: Skype squealing of high-field with speakers muted
What is the cause?
http://www.YouTube.com/watch?v=mrR8Mq8VAO0&feature=youtu.be
My Lenovo Thinkpad X220T making sounds very strange, treble when Skype starts - even if I cut the speakers. The model of the sound is always the same, indicating that Skype should do whenever he starts.
This video was filmed with a Samsung Galaxy S, and you may need headphones/good speakers to hear the sound. Despite a lot of noise (fan of the computer), there is no other loud sounds to break your hearing with - then turn up the volume.
Very likely groan of CPU. Workaround is to disable CPU power management, which significantly increases the consumption and production of heat.

Problem with Spotlight fields with the higher priority than browserfield
It comes to JRE6.
Some Web sites make a redirect of content or another ajax request when the document is loaded. When the screen contains a browserfield and a focusable field with a higher priority, an illegal state Exception is thrown by the browser because it is not to the point when the content refreshes the field. (As in defining BrowserField.setFocus () before calling BrowserField.refresh ()).
Using the code of the BrowserField2 example, simply by adding a ButtonField in the survey except title when navigating to twitter.com. Other sites work fine, but when the content/javascript is in a certain way on Twitter, she seems to have some problems.
package mypackage; import net.rim.device.api.ui.component.ButtonField; import net.rim.device.api.ui.container.*; import net.rim.device.api.browser.field2.*; import net.rim.device.api.ui.*; class MyBrowserField2Sample extends UiApplication { private MainScreen _screen; private BrowserField _bf2; private ButtonField btnField; MyBrowserField2Sample() { btnField = new ButtonField(); btnField.setLabel("A BUTTON"); _bf2 = new BrowserField(); _screen = new MainScreen(); _screen.setTitle(btnField); _screen.add(_bf2); pushScreen(_screen); _bf2.requestContent("http://www.twitter.com"); } public static void main(String[] args) { MyBrowserField2Sample app = new MyBrowserField2Sample(); app.enterEventDispatcher(); } }
The code above throws an illegal state exception at startup. If you delete the setTitle (or any field focusable) that has a higher priority than the browserfield, so it works well.
How can I force the focus on the browserfield when she needs?
I Googled, found issues similar and all say "force focus on the browserfield", but even if you force the focus, the same illegal state occurs due to the updating of the content.
Thanks in advance,
Nate
After reviewing the matter further, the problem may be to the field focusable, but it doesn't have to be on top. Basically, any field focusable on the same screen as the browserfield throws the exception.
While going to twitter.com in blackberry browser works very well (sends you to the mobile site), this behavior causes problems with the browserfield.
The workaround, is just to force the link to open the mobile site directly.

How Skype number I can buy with the same ID
Hello
I just want to know how many Skyp No. I can buy with my unique skyp ID.
If I want to buy then a Skype number I have to create a new ID skpye, or by several, I train same ID?
Hi, Skype606, and welcome to the Skype community,
A Skype account can have ten 10 Skype number subscriptions attached to it.
Please note, however, if you need to respond individually to each number or have a separate for each number of Skype Voicemail, then you will need to set up a separate Skype account for each number of Skype.
Kind regards
Elaine

One of the HP monitors have loudspeakers built-in and audio output ports that can connect to external speakers?
Hello
Check this box:

I think not only considered the monitor speakers is a good idea, you need many cables aound except pass by wireless. Just buy a monitor with speakers builtin (many brands autour).

A measure of speed high speed with encoder in quadrature and NI 9401 on cDaq
Greetings,
We use an encoder in quadrature with 360 pulses/turn on the tracks (track A and B) and no trace of Z to measure motor speed at startup. Data acquisition, we use a NI 9401 in 9178 cDaq chassis and a pc with LabVIEW. The problem is that the start-up period is relatively short (less than 1 second), during which we measure speed as precisely as possible. The speed range is from 0 to 10000 RPM.
What type of measurement method that you would recommend.
Here are a few methods that we have already tried:
-Measure with DAQmx CIFreq--> high frequency with 2 counters: speed measurement, but with a very big mistake (+ 166 RPM).
-CIFreq DAQmx--> wide range with 2 counters: good speed data but more slow measurement,
-CICntEdges DAQmx (counting separated the two lanes, speed conversion): very incoherent speed data.
Thanks in advance for your help.
Matej
I would definitely say a 4, the measure of a low freq called option with 1 meter. (Frankly, I've never been
fond of this name because it is useful for freqs much higher than what I expect most people think "low freq".) This
is the method that I almost * always * use for frequency of counter measures. It works really well to capture transitional
variations in speed.
10000 rpm and 360 cycles/rev, you are looking at a maximum frequency of 60 kHz. The frequency measurement mode 1 meter
There will be 80 MHz internal clock by encoder cycle edges, then you will get more than 1000 strokes per measure. The point
that means only 1 number of quantization errors, you can expect<>
Further, you can average overall, say, 10 samples to you give even better accuracy and you could still be a data capture
rate significantly higher than the probable bandwidth of your mechanical system. (The average would just clean the jitter and noise and would not
Hide answer true mechanical characteristics).

Realtek High Defination Audio speakers is not plugged in, no sound in Windows
Hi guys.
I got my PC for about 2 years now, and all of a sudden my audio stopped working. When I go to manage my audio devices in the Control Panel, it says "realtek high definition audio speakers are not connected. I use the onboard sound on the motherboard Asus Maximus V extreme.
Therefore, the realtek digital output has been selected automatically. I since changed it NVIDIA high definition audio digital output - so that sound for now plays on my speakers monitors via the HDMI cable.
I tried my speakers on an MP3 player and they work no - including the cable, so the speakers and cable are not a problem.
I tried to restore the pc to a time where noise - WORKS DO not STILL working.
Downloaded the latest drivers Realtek and installed - DOES NOT ALWAYS WORK.
Deleted the latest drivers and install them from the CD of motherboard drivers - DOES NOT ALWAYS WORK.
I disabled all audio devices, hoping that speakers will then - DO WORKS not ALWAYS. Help, please...
System:
Windows 7 Pro 64-bit

Text field with AutoComplete do not store Item Value for Cascading LOV
Hello
I have created a form to the APEX 4.2, and two elements on the page have a problem. The first point is a text field with AutoComplete for the PROVIDER. The second element is a list select number that has the PROVIDER as part of waterfall to fill.
When a user selects one of the values that the field can be seized semiautomatic provider , the value autocomplété should make the selection list produce the numbers respective associated PROVIDER. The problem that I am running is that AutoComplete is not give PROVIDER selection list value is filled.
For example: if I type 'st' in the PROVIDER field that autocompletes to "steve" is selected, the NUMBER field must interrogate him for the numbers where VENDOR = steve. However, after reviewing the Session State from the PROVIDER element, the contained value is always only "st."
Here are the settings I have for the field PROVIDER : and NUMBER:
There should be a way to have the value of the seized field semi-automatic to account for what appears after selecting a value, but I don't know what it is. You can provide any help would be appreciated.
Thank you!
your query full auto would: select supplier_name | ' ('| supplier_id |') '

f: Validator field with dependencies on line table
Hi guys,.
I have a built with a custom SQL view object. I created a page with a table jsf, users can edit all fields and later this information he was send by webservice.
A field has a validator. This validator check if not equal 0. Now, I add a new condition, when the other field equals 0 then should not see the error.
Example:
Field1 Field2
2 0-> error, Field2 0 and Field1 is not 0.
Change Field2
2 1-> OK-> Field2 is not equal 0
Change Field2
2-> 0 error, Field2 0 and Field1 is not 0
Change Field1
0 0-> OK, Field2 0 but field1 0
I added a validator attribute, but it does work very well. I thought of using required field with groovy expression but it is not working properly, but when field2 is 0, it is compelled value.
I don't know how this implementation.
Any idea?
Thank you!
Kind regards.
Hello AlfreNet,
Sorry for the delay, but he questions and I m there (maybe all) do not get warnings in my Inbox (Inbox does not).
For the table, you can iterate trought the lines as its explained Timo Hahn in this post: Hello, I am using j developer 12.1.3 ;
On the action of the button, I think you can do as explained on that: Re: conditional Navigation on the CommandButton Action use EL? to only return the string to navigate when there are no validation errors, otherwise return null and show the message; (I have a request that the action of the button returns a string based on the review of the method and redirects accordingly, but I m not finding any to show you, sorry).
Kind regards

How to create the equivalent of 'field with AutoComplete text' in a report updated
I have a region based on a relationship of type "SQL Query (updateable report)". "
The table that the report is based on a a comment field that users should be able to update. Currently, it is defined as ' display as '-text field, to allow users to change.
I want to be able to provide users a standard set of comments from which they can choose, if they wish, OR to put in another comment or to choose a standard comment and change, that is very much like a drop-down list box.
Other types of fields can be defined as "text field with AutoComplete", which would be fine if I could put it on this area, but in such field, on this type of regions, it is not possible.
Is it possible that I can create a work around to get the same effect.
Thank you
Dave
Hello
It turns out that due to my need is satisfied by the standard features.
I was looking for "offering users a standard set of comments from which they can choose, if they wish, OR to put in another comment or to choose a standard comment and change, IE a lot as a combo box"
The answer is a Popup LOV. (As opposed to a Select list).
Selecting a popup LOV will bring back the text in the field AND ALLOW the EDITION. And if you do not use the context menu, you can always change the field.
If you want to get AutoComplete on it as well, then try code of Jari.

Fill a field with the results of the other (sort and add custom text)
I have a PDF form with many fields popup asking 'Yes', 'Maybe' or 'no '. I need a way to collect the answers and sorting, all the 'yes' first of all, that all the 'maybe', all the 'no '. When I need after that sort of response of three, is put in a 'Results' field with the container of the ToolTips for each popup and the ability to add a "BOLD" text, between three sorted responses.
I have found some javascript in the forum here to collect data from field only. It seems to be easy to modify if you have several fields to collect/sorting/extract.
Assistance or management to do will be appreciated.
Thank you!
Assuming that you have 50 menus named A1, A2... A50 and each drop-down list has three elements (Yes, maybe, no), you could do something like:
Initialize object to contain the info of the answer
var oResponse = {}
'Yes': [],.
"Maybe": [],.
['No':]
};
var i, f;
Browse fields (A1, A2... A50)
for (i = 1; i<= 50;="" i="" +="1)">=>
Get a reference to the current field
f = getField ("A" + i);
Add ToolTip text of the current field to the corresponding table in the response object
oResponse [f.valueAsString] .push (f.userName);
}
Generate the output string
aOutput var = [];
If (oResponse ['yes'] .length > 0) aOutput.push ("It's the priority YES\r" + oResponse ["Yes"] .join ("\r"));
If (oResponse ["Maybe"] .length > 0) aOutput.push ("It's the priority MAYBE\r" + oResponse ["Maybe"] .join ("\r"));
If (oResponse ['No'] .length > 0) aOutput.push ("It's the priority NO\r" + oResponse ["No"] .join ("\r"));
Enter the results
getField("Results").value = aOutput.join("\r\r");
