Sound file path

Hi Everyone,
I'm using the sound file path to play with Play Sounf File.vi.
I have to select the file again everytime I close and open labview.
Any suggestion as to how I can make it permanent?
Thanks.
Solved!
Go to Solution.

Two things to do
1) In Front panel right click on control and select data operations->make current value default, then save
2) In the block diagram right click and select change to constant, then save
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

How do I set the default file path for the Place command?

I keep my graphics files for each document in a particular folder. Every time I open an existing InDesign document and place a new image I have to browse back to that location - even though all of the previous images in that document came from the same folder. InDesign does not remember the file path that was used previously in the document. This is very annoying.
IS THERE A WAY TO SET THE DEFAULT FILE PATH, OR LOCATION, FOR IMAGE FILES?
I have looked through the preferences, searched the forums and internet, but I have not found any reference to setting default paths. Is there a setting like the one in MS Word called "File Locations" on the Options toolbox?
Thank you.

Since you're working in ID on Windows, you can take advantage of a neat trick in Windows. Copy the file path out of the File Explorer address bar and paste it directly into the Place filename field. That will jump you directly to the desired volume. For example, let's say I want to place a graphic located at X:\PS Jobs\May PS\709672bp\Working Source Files\Links. I copy that entire path from the File Explorer address bar, go to InDesign, select File|Place, and press Control + V to paste that path into the filename field. I press the Open button and Shazam! I'm there instantly, without a bunch of navigation.
You can do the same thing in the File|Save As and File|Export fields. Let's say you want export a PDF file from InDesign to the volume X:\PS Jobs\May PS\709672bp\Working PDF Files. First copy the desired file path from the File Explorer window. In InDesign, select File|Export, click anywhere in the filename field, and press the Home key to move the insertion point to the front of the filename. Press Control + V to paste that path in front of the filename, then add the backslash character (\). The filename will now look like this: X:\PS Jobs\May PS\709672bp\Working PDF Files\Filename.pdf. Press the Save button to bring up the Export Adobe PDF window. Select your desired PDF preset, press the Export button, and the PDF file will magically appear in the desired volume.
This sounds really complicated, but it's not. In practice, it only takes a few seconds. I probably save an hour's worth of needless navigation every day with this technique.

Problem with playing a sound file.

Hi,
I simply want to play a sound by a button click. I imported
<AVFoundation/AVAudioPlayer.h>. The code block is here:
In .h file:
#import <UIKit/UIKit.h>
#import <AVFoundation/AVAudioPlayer.h>
@interface PlaySoundViewController : UIViewController <AVAudioPlayerDelegate>
in .m file:
-(IBAction)btnPlay:(id)sender
    //Get the filename of the sound file:
    NSString *path = [[NSBundle mainBundle] pathForResource:@"REC001" ofType:@"MP3"];
    AVAudioPlayer* thePlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];//error here as it will compile if I commented it (and two line after) out.
    thePlayer.delegate = self;
    [thePlayer play];
Everything looks fine but it failed when I tried to run it. Looks like it cannot find my sound file "REC001.MP3". I put it in folder ".../PlaySound/Resource Files/SoundFiles/REC001.MP3", and "PlaySound" is my project name. However the path returned is ".../PlaySound/REC001.MP3". I guess this is why it cannot find the object. But it didn't work even I put the sound file under "PlaySound" directly. Anyone has a solution?
Thanks.

Taizhi

Hi Mark,
Thanks for the reply. Based on your instruction, I checked and I can see the sound files in Build Phases. The location is ".../PlaySound/SoundFiles/REC001.MP3". I don't know why it ignores folder "Resource Files". I guess that is the way it is as I also can see other images in different folders which are shown properly in the project.
The detailed error message is here:

Is the framework AVFoundation I added wrong? Thanks.

D11.5 Projector gets stuck on encountering first sound file

My projector runs fine on my PC (where I have D11.5) but when pack up all the files and try to play it from a new machine, the projector plays the opening screen and as soon as it has to make the first sound, it freezes. It seems as if it can not find the sound. I tried putting the sound file right next to the projector and even that does not work.
My usual method is to call the sound files with the path such as
sound playfile 1, the moviepath & "sounds\" & "playThisSound.aif"
This works just fine on my machine. The projector does not hang up.
Any ideas?

You are using ancient and deprecated Lingo to play sounds. Try importing them into a castLib and use sound(channel).play() or a new mixer object (consult the docs)

Hi Vehnasa1,
Looks to me like your program started from the Sound File to Sound Output.vi example.
Does this example play *.wav files for you?
On my computer it is located here:
C:\Program Files (x86)\National Instruments\LabVIEW 2011\examples\sound2\sound2.llb\Sound File to Sound Output.vi
You are also indexing an array of paths that are all the same.

Automatic file path pages

How do I add a file path in a new file of Pages ?

In Pages '09:
Menu > File > Insert File Name
It sounds like you may have Pages 5 on Mac OSX 10.9 (Maverick).
Apple has removed over 90 features from Pages 5.
http://www.freeforum101.com/iworktipsntrick/viewforum.php?f=22&sid=3527487677f0c 6fa05b6297cd00f8eb9&mforum=iworktipsntrick
Pages '09 should still be in your Applications/iWork folder.
Archive/trash Pages 5 and rate/review it in the App Store, then get back to work.

Show Full File Path

I have no luck locating the full file path to a Photoshop document in CS5. I have tried hovering my cursor over the short title in the tab for the document, but I only get the name of the document.
I am on XP Professional.
I don't have this problem on another computer which I use that runs Vista.

Hi Noel,
Thanks for the help. I am refering to documents opened from disk, not new documents. I ended up writting a script that I have a hotkey assigned to that brings up an alert dialog with the path to the file on disk:
The whole issue is: I have opened a bunch of files in PS, some may be duplicate images in different locations, or "I just want to know where [on disk] this image is that I am working on" without having to close-reopen, go to the recent list, or other series of steps. I know this may sound kinda lame at first look, "Hey doesn't he know where the file is that he just opened?", but working in the games industry I, at times, have many files open or am moving from one [disk] location to another and it is just VERY convenient to have the file path info readily available in PS.
BTW: A cooler windows util for getting/copying the path (in a variety of ways) of a file in windows explorer is the context util called Path Copy: http://download.cnet.com/Path-Copy/3000-2072_4-10036463.html. Which looks like this:

Search c:\ drive and return file path for winword.exe and save as variable

Hi all, here is what I'm trying to do;
1. Search C:\ drive for winword.exe
2. take the file path and save it as a variable.
3. Then based on the path value, use the switch statement to run "some command"
Essentially I'm trying to find what the file path for winword.exe is, then run a command to modify the registry. I already have the script that will modify the registry like I want but the problem it, the path is hard coded in the script, I want to
now look for all versions of word and set the right file path so I can make the right registry changes.

This should get you started:

What is a Logical and Physical file path in sap?

what is a Logical and Physical file path in sap?

Hi,
Physical file is what you see from the OS level.
Logical file is what ABAP code can call certain functions to read/write.
Transaction FILE would link them together. Typically the logical path ends with "<FILENAME>", and the logical file refers to the logical path.
To extract the physical path from the logical path name
DATA: lf_mandt TYPE sy-mandt,
        lf_opsys TYPE sy-opsys.
lf_mandt = sy-mandt.
lf_opsys = sy-opsys.
To extract the physical path from the logical path name
CALL FUNCTION 'FILE_GET_NAME'
    EXPORTING
      client           = lf_mandt
      logical_filename = p_unix
      operating_system = lf_opsys
    IMPORTING
      file_name        = gwa_input
    EXCEPTIONS
      file_not_found   = 1
      OTHERS           = 2.
IF sy-subrc EQ 0.
Concatenating the physical path and the input unix file name
    CONCATENATE gwa_input p_file INTO gf_file .

Inserting file path/filename

Hi, all out there,
I've just strated using Pages '08, and exploring it. But Pages Help and User Guide do not tell me how to insert the file path or filename in the footer, so that it's automatically updated whenever changed. It's not in the Insert menu, and cannot find it in Insert > Function.

Hi Peggy,
Though that feature is useful isn't found in 10.4.10. The Devon Technologies WordService ReadMe file has the following:
Insert:
Contents Of Path
Inserts files and folders of the selected path (tilde is expanded)
and of all its subdirectories (e.g. select the path '~/' and this function
will insert all contents of your home directory)
Short Date Cmd-'{'
Inserts the current date (no text selection necessary)
Long Date Cmd-'}'
Inserts the current date (no text selection necessary)
Short Date & Time Cmd-'_'
Insert the current date & time (no text selection necessary) Long Date & Time Cmd-'%'
Insert the current date & time (no text selection necessary) Time
Insert the current time (no text selection necessary)
Maybe that's what you're seeing in your services menu perhaps.
Sincerely,
RicD

How can I transfer a sound file from my "Voice Memos" app on my iPhone to my iPad?

How can I transfer a sound file from my "Voice Memos" app on my iPhone to my iPad?

In iTunes with your iPhone connected, click on the iPhone device, select the Apps tab, scroll down to the File Sharing section and pick an app that plays Quicktimes ("Files Connect" works in this example, but I'm open to suggestions of better apps for playing transferred Quicktimes) and drag your Quicktime from Finder to the Documents pane for the File Sharing app. Once the file transfer is complete, go to the app on your iPhone to play the Quicktime.

How to get a list of file paths for all files used in a project

I have a project in Premiere Pro CC which has a large number of bins. A sequence in one of these bins uses files from other bins. I am trying to find the locations of all each of the files used in the project.
1) Obviously I can select each clip in the timeline and show in finder, but there a lot of clips
2) The video usage associated with each file in the project would help. However
1. I haven't found a way to display only clips that have video useage if all of the bins have not been expanded.
2. Video usage shows usage for all sequences, so one would have to manually check the pull down for each file to see if it is used in the sequence in question.
3) I tried exporting the project to final cut pro xml. The path url gives me the information that I need. For some reason, however, when I do the export only one clip's information is there, not the information for all of the other clips in the project.
4) I tired an export for speedgrade and all of the file names are there. However the paths are not.
Basically I want to find all of the files in the project and relocate them to a specific folder for that project. There's got to be a way to do this but I'm not seeing it ....

Thanks for the suggestion concerning the file path. And certainly it would have been nice to have done this before beginning. However this is a project that has been around for quite a while, and the files have been moved into different bins. And now the project sequence is being revised.
So the problem is, worded slightly differently, how can I search all of the bins for the files that are used just by this sequence, ignoring the files which are used by other sequences? Or, how can I get a list of the file paths of the files that are used in the sequence?
