How to use an binary stream file to generate Arb from Agilent 33250A?
I used Lv6.1 and ag33xxx.llb (download from NI web page). And I want to generate Arb waveform from Agilent33250A, this Arb according to an binary stream file, just like 0101110010100011.......
I used "Getting Started 2.vi" module, to try first, and all setting used default value. Instrument can be remote controlled. But what I can see from oscilloscope is very strange. The waveform is start with several sine wave (at very high voltage even to 40Vpp!!) and then several sine wave (at low voltage), then at about 0v. It is not what I want!
And, if I changed Frequecy or 0/1 data, NOTHING changed of output waveform.
On Agilent web site, I found there are some vi examples for Agilent33250A. But I can NOT read it for all vi modules in ag33250a.llb. I'm puzzled about where can I find this file ag33250a.llb.
I'm not sure what's the problem with "Getting Started 2.vi" module, or anything incorrect of my setting. And I want to know how can I do for my project right now?
I appreciate the help.
Thanks, Werner.
I used Agilent54622D scope to check Agilent33250A output directly via coaxial-cable.
Firstly, that's my mistake to not change scope setting "Probe scale" to 0.5:1, (default is 10:1).
Then I opened LV ag33xxx.llb (download on NI web site) --> ag33xxx - Getting Started.vi. Select "waveform shape" is Sine, Freq is 1KHz, Amplitude is 1Vpp. Run this vi, I can get correct sine wave from scope. Then select some other waveform, such as square and triangle, all are correct.
After above, I opened "ag33xxx - Getting Started 2.vi", it is used for Arb function. Run this vi directly, output waveform is in attachment. If I changed Freq, nothing changed of waveform.
So, I'm puzzled about it. Where the issue is?
You can use Arb mode successfully. How to do it?

Yue

When using Multicam in CS6 how do I choose which source file the audio comes from?
I've noticed when using the Multi-cam window to create edits, the audio does not change when I select the different video sources. How do I select which source file the audio comes from?
It doesn't make sense why the multicam source sequence only uses one track of audio. Was this by design? The issue with this as in my situation (and because I didn't know this) I recorded all my source videos with the music tracks on the right side which is what I'm using to cut my video with. Not being able to hear this while I'm cutting is really frustrating. There's a reason I separate dialog on the left side and music on the right. There should at a minimum be an option while setting up the multicam to choose more audio options. Even in the audio clip option settings, those don't seem to work when a clip is put into a multicam source sequence.
The other issue is when you bring in the audio after the fact or even before, there's no way to sync timecode with audio to the multicam sequence. When I create the Multicam source sequences in my project bin, I choose sync with timecode, not in points, because the record decks I'm using are all locked with a TC gen during the shoot.
Maybe I'm missing something, but there seems to be either a bug with multicam or a design flaw. Even in the help documentation, it states multiple audio tracks can be brought in with the multicam sequence, but only track one is enabled by default. I've never been able to have the MC sequence bring in more than one track of audio no matter what the audio settings are. -
How can i bulk rename music files in reverse order from artist - song name to songname - artist
How can I bulk rename music files in reverse order from artist - song name to songname - artist.
I actually dont need to rename the actual files.
Its just i have a huge txt list of 100,000 music names that are listed as so..
Artist - Song Name
Artist - Song Name
Artist - Song Name
Artist - Song Name
Artist - Song Name
Artist - Song Name
and i need this list to reverse it self so it is listed in the list as
Song Name - Artist
Song Name - Artist
Song Name - Artist
Song Name - Artist
Song Name - Artist
Song Name - Artist
Song Name - Artist
Im sure there is some kinda way to auto a mix of applescript/automator/terminal to do something like: all char before the "-" replace with the chars after the "-".
Please some one help me if you know how I can pull this offHow can I bulk rename music files in reverse order from artist - song name to songname - artist.

I wonder if we haven't misunderstood what you were asking for. Could it be that you have not a huge file, but just a huge list of names in many small files. If that's the case, you should rather use the following script instead of the previous one.
Since this script does not rename the files, make a backup of your files before running it.
set theFolder to choose folder -- the folder containing your text files
tell application "Finder"
set theNames to name of files of theFolder whose name extension is "txt"
end tell
set theTextFiles to {}
set theFolderPath to POSIX path of theFolder
repeat with thisName in theNames
copy theFolderPath & thisName to the end of theTextFiles
end repeat
repeat with thisFile in theTextFiles
set F1 to open for access thisFile
set theText to read F1
close access F1
set theParagraphs to paragraphs of theText
set bigList to (a reference to theParagraphs)
set theNewParagraphs to {}
set bigNewList to (a reference to theNewParagraphs)
repeat with X in bigList
set P to offset of " - " in X
if P = 0 then
set Y to X
else
set Y to text (P + 3) through -1 of X & " - " & text 1 through (P - 1) of X
end if
copy Y & return to the end of bigNewList
end repeat
set theNewText to text 1 through -2 of (bigNewList as text)
set F2 to open for access thisFile with write permission
set eof F2 to 0
write theNewText to F2
close access F2

hi
ideally if you want to print from the ipad you should have an airprint enabled printer:

Ummm... why would you want to get MSPaint anyway? Even in the absense of real software, Java's own graphics tools are way more sophisticated - with a little time and effort, you could write a simple paint package that beat MSPaint hands down.

How do you change application used to play streaming file?
I can change the application used to open a file directly on my computer by going to the Get Info for the file. However, I am trying to get a streaming file to play using QuickTime instead of Real Player (it's a SDP file from a Darwin Streaming Server) and there is no file to "Get Info" on. Real seems to have the .sdp extension locked up. Long time ago, you used to be able to go to a control panel and change the default application for certain file types. I cannot seem to find that anymore under Tiger. Anyone know how to do this?
Ok, I sorted it out. You have to do the following:
a) Open System Preferences > Quick Time > Advanced > MIME Settings. Click on the "Streaming - Streaming movies" triangle to expand it and make sure that the button nest to "SDP stream descriptor" is checked. Quit System Preferences.
b) Launch Real Player and go to its Preferences > Media Types. Uncheck the "Real-Time Streaming Protocol" and "Scalable Multicast" buttons. Click on "Save Media Types" on bottom Left (if it ask you to quit your browser, allow it to do so). That should do it. As far as I can tell this does not affect the streaming of .ram files. -
How to use a packaged Jar File?
Greetings to everyone reading this post!
I have a query about a thing that seems to be basic but I don't know how to accomplish, here it goes:
I have packaged a Simple application into a Jar file. this application contains a package like this:
lib.demo, inside this package I have a Class named MyClass with some simple methods like this one:
public void sayHi(String name){
//implementation here
}Now, I would like to Know how to use the Method sayHI(String name) from an entirely different Project. I have successfully included the Jar File as a Library(in the new Project), but I have I no Clue on How to invoke a Class inside my Jar library, and more Importantly, a method.
Could anybody help me?if the "project" (not a Java-related system, it's IDE-specific) already includes the JAR file in its classpath (library), then all you need is to import the package/class and invoke the method, as such:
// in your client code:
import lib.demo.*; // or, import lib.demo.MyClass;
public class Test {
public void inAMethod() {
MyClass myC = new MyClass();
myC.sayHi("say hi");
}simple. -
Hi,
I am trying to use a binary library (Xerces 2.9.0). I would like to know if there is a way to use this library by putting it in my project path and using an import statement to do so. I did this with a version of entagged and placed it in "lib\\entagged" (where my compiled classes are located) and used the folder hierarchy:
import lib.entagged.*;Is it possible to do the same with a binary package as in the image linked here:
http://img251.imageshack.us/img251/441/xercesnm4.jpg
This would make it easier to compile and use across multiple computers...
Thanks in advanceThanks Peter for the reply

you are not looking for a standard binary searchI'm not using a binary search in the very common I'm searching for a particular key sense, which is the Collections.binarySearch sense. But binary searches are used in other situations as well. In this case I'm finding a local maximum of a function, I could also be solving f(x)=0... is there a nice generic way to handle other uses of binary search that anyone knows of?
I would just copy the code from Collections.binarySearch and modify itI have this thing about reusing; just can't bring myself to do that :)
It would be quicker and more efficient than trying to shoe horn a solution which expects a trinary result.Not sure I understand the last bit. Are you referring to my bastardised compareTo method with only two results? If so, I know, it is ugly! I don't see how it could be less efficient though???

How to use Sharepoint 2013 img file
Hi,
I downloaded Sharepoint 2013 as an img file. I am trying to install it on VMWare 5.1 which only accepts ISO files. How can I convert the img file to ISO or what other workarounds are available?
I already tried renaming the file to ISO, but it didn't work.
ThanksHi WaelS,
If you want to use img file in VMWare, you may need to convert the img file to ISO, as VMWare doen't support img file.
Please do as the followings to convert the img file to iso:
1. Unzip the files
2. Open a command prompt (Start > Run > type cmd, press Enter)
3. Browse to the folder where the unzipped files are (cd "c:\Windows ISO Files")
4. Considering that you are in the folder containing the files command prompt, type
copy /b file1+file2+file3+file4+file5 file.iso
4a. Check that the files have no extension. If they have, the command changes to something like:
copy /b file1.ext+file2.ext+file3.ext+file4.ext+file5.ext file.iso
4b. If there aren't *any* other files in the folder, typing this should be enough:
copy /b *.* dvd_file.iso
If you still have question about the issue, I suggest you can post a thread in corresponding forum, you will get more helpful information from there.
