Trying to make a file viewer

I am trying to make a program which allows the user to select a file and display it on the screen in LabVIEW 6.1. My problem is that the Picture control seems to hold the previous as well as the current pictures. I am new to using image applications in LabVIEW and cannot find a way to erase the image (if I send an empty image it just goes into the rotation).
Can anyone offer some suggestions?

I'm not sure if this is what you mean, but attached is a small example program demonstrating the effect of the "Erase First" Property.
If you run the vi with Erase true, toggling the top switch between runs results in either one or two circles being drawn. If you set Erase to false, the drawing will always show two circles, regardless of the position of the top switch, or more accurately, any new drawing is simply layered on top of what's already there.

Trying to make a file alias, but I'm stuck!

I've come up with 3 ways to do the same thing, and none of them work..
I want a droplet where I can drop a file (this case, a photo) and then an alias is created in another specified folder on the desktop. I have a hundreds of photos to go thru and i want to have a shortcut to the ones that are approved, so I can go back later and photoshop them. I don't want to double up on the photos and I want to keep the structure they're in now, so I don't want to move them.
Where am I going wrong with any one of these...??
*Script 1*
on open draggeditems
tell application "Finder"
set draggeditem to theFile
make new alias of file in folder "Approved" of folder "Desktop" of folder "kit" of folder "Users" of startup disk to theFile
end tell
end open
Returns: The variable theFile is not defined.
*Script 2*
on open draggeditems
tell application "Finder"
set draggeditems to input
set alias of the input to make new alias file at folder "Approved" of folder "Desktop" of folder "kit" of folder "Users" of startup disk to input
end tell
end open
Returns: The variable input is not defined.
*Script 3*
on open draggeditems
tell application "Finder"
set sourcefiles to thisFile(draggeditems)
repeat with thisFile in sourcefiles
tell application "Finder" to reveal item thisFile
set thisFile to thisFile as alias
set alias of file in folder "Approved" of folder "Desktop" of folder "kit" of folder "Users" of startup disk to thisFile
end repeat
end tell
end open
Returns: Can't continue thisFile.
I realise there's a trend showing here, but I can't seem to break it..

The errors are fairly straightforward when you realize what's going on.
In scenario 1:
on open draggeditems
so 'draggeditems' is a list of the files that were passed to your script.
Two lines later you say:
set draggeditem to theFile
So now you're trying to set 'draggeditem' to 'theFile', but nowhere in your script is theFile defined. Hence the error.
I'm assuming you want to extract each file from the list of draggeditems, in which case you want something like:
<pre class=command>repeat with theFile in draggeditems</pre>
so now 'theFile' contains a reference to each file in turn. From there you can make an alias to it:
<pre class=command>make new alias to file theFile at folder "Approved" of (path to Desktop)</pre>
So, in all your script should look more like:
on open draggedItems
repeat with theFile in draggedItems
  tell application "Finder"
   make new alias to file theFile at folder "Approved" of (path to Desktop)
  end tell
end repeat
end open</pre>

Problem trying to transfer multiple file over a network or the internet

Hello I'm trying to make a file transfer program to transfer file over the internet or a network. I've been able to successfully transfer one file but when I try to send multiple files I keep getting a EOFException after the client trys to send the files. The client says it sent both files and the connection was closed but the server said that it only received one file and throws a EOFException. I've included the code from the client and the server. Any help is much appreciated.
The Client
private class createSocket implements Runnable {
          String address;
          int port;
          public createSocket ( String address, int port ) {
               this.address = address;
               this.port = port;
          public void run() {
               try {
               postStatusMsg( "Opening Connection at " + address + ":" + port );
               Socket socket = new Socket( address, port );
               postStatusMsg( "Connected to " + address + ":" + port );
               DataOutputStream dos = new DataOutputStream( socket.getOutputStream() );
               DataInputStream dis = new DataInputStream( socket.getInputStream() );
               dos.writeInt( files.length );
               for ( File f : files ) {
                    BufferedOutputStream out = new BufferedOutputStream( dos );
                    BufferedInputStream in = new BufferedInputStream( new FileInputStream(f) );
                    postStatusMsg( "Sending: " + f.getName() );
                    byte[] b = new byte[8192];
                    int read = -1;
                    dos.writeUTF( f.getName() );
                    while ( ( read = in.read( b ) ) >= 0 ) {
                         out.write( b, 0, read );
                    postStatusMsg( "File Sent" );
                    in.close();
               dos.close();
               postStatusMsg( "Closing Connection" );
               socket.close();
               postStatusMsg( "Connection Closed" );
          catch( IOException e ) {
               Main.ShowMsgBox( statusTA, "Error", e.getMessage(), JOptionPane.ERROR_MESSAGE );
               try {
                    e.printStackTrace( new PrintStream( "./log.txt" ) );
               catch ( FileNotFoundException ee ) {
                    ee.printStackTrace();
     }The Server
public class ServerHandler implements Runnable {
          private Socket s = null;
          public ServerHandler( Socket s ) {
               this.s = s;
          public void run() {
               try {
                    handlers.add( this );
                    DataInputStream dis = new DataInputStream( s.getInputStream() );
                    DataOutputStream dos = new DataOutputStream( s.getOutputStream() );
                    BufferedInputStream in = new BufferedInputStream( dis );
                    BufferedOutputStream out = null;
                    int count = dis.readInt();
                    for ( int i = 0; i < count; i++ ) {
                         File f = new File( Main.settings.SAVE_DIR );
                         if ( !f.isDirectory() )
                              f.mkdir();
                         f = new File( Main.settings.SAVE_DIR + "\\" + dis.readUTF() );
                         out = new BufferedOutputStream( new FileOutputStream( f ) );
                         postStatusMsg( "Receving: " + f.getName() );
                         byte[] b = new byte[8192];
                         int read = -1;
                         while ( ( read = in.read( b ) ) >= 0 ) {
                              out.write( b, 0, read );
                         postStatusMsg( "File Received" );
                         out.close();
                    in.close();
                    postStatusMsg( "Closing Connection" );
                    s.close();
                    postStatusMsg( "Connection Closed" );
                    handlers.remove( this );
               catch ( IOException e ) {
                    Main.ShowMsgBox( statusTA, "Error", e.getMessage(), JOptionPane.ERROR_MESSAGE );
                    try {
                         e.printStackTrace( new PrintStream( "./log.txt" ) );
                    catch ( FileNotFoundException ee ) {
                         ee.printStackTrace();
     }

Something like this, modulo bugs:
// sender
dos.writeLong(file.length());
// send the file
// receiver
long length = dos.readLong();
long current = 0;
int count;
while (current < length && (count = in.read(buffer, 0, (int)Math.min(buffer.length, length-current))) > 0)
out.write(buffer, 0, count);
current += count;
}

Trying to make a text file of ITunes library

I'm trying to make a list of my itunes library in any type of text file (word, notebook, notepad,etc). My ex sent me an old library this way just so that I could see what I already had at his place so I wouldn't duplicate things. How do I do this??

In iTunes, use View > Options to show the fields you want to show. Then Edit > Select All, then Edit Copy.
Open Word and use *Paste Special > Unformatted Text.*
Try it first on a short playlist so you can see how it works.

I am trying to make a pdf of a file and I need to get the file size to be no bigger than 10MB. What is the best way to do this

I am trying to make a pdf of a file and I need to get the file size to be no bigger than 10MB. Even when I save it, the image quality at minimum the file size is 10.9 MB. What is the best way to do this

@Barbara – What purpose is that PDF for? Print? Web?
If web purpose, you could convert CMYK images to sRGB. That would reduce the file size as well.
A final resort to bring down file size is:
1. Print to PostScript
2. Distill to PDF
That would bring file size down even more. About 20%, depending on the images and other contents you are using, compared with the Acrobat Pro method. If you like you could send me a personal message, so we could exchange mail addresses. I could test for you. Just provide the highres PDF without any downsampling and transparency intact. Best provide a PDF/X-4.
I will place the PDF in InDesign, print to PostScript, distill to PDF.

Trying to copy ANY file from my MacBook Pro to an external hard drive spins for 45 minutes then fails. I hate this computer and WISH I never would have wasted my money. Any ideas? WD My Passport 2TB Drive, had to buy a program to make the POS read files. Copies that would take seconds from a Windows based machine never complete. I have to close the transfer or shut off the machine half the time. Worst computer I have EVER owned, crashes non-stop, constantly freezes, and seems like EVERY operation is more complicated with this thing. Literally, my 1997 Compaq was FAR MORE reliable and user friendly.

This is one of the messages I keep getting; The Finder can’t complete the operation because some data in -- File Whatever -- can’t be read or written.(Error code -36)
I have copied things to the hard drive in the past, but it has always been incredibly slow, and now just seems to freeze and fail

I am getting this response when I am trying to open a file: Before viewing PDF documents in this browser you must launch Adobe Reader and accept the End User License Agreement, then Quit and relaunch the browser.” What do I do? I have opened this up in the past without a problem.

Back up all data.
If Adobe Reader or Acrobat is installed, there should be a setting in its preferences such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected. Otherwise do as follows.
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard (command-C):
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, remove any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present. The same goes for a plugin called "iGetter," and perhaps others.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

Are you looking for iPodService.exe?
Might be better to run services.msc from the run dialog and shut down the service polietly.

I get this message when I am trying to save a file that was done in CS4, now using CS6 "Cannot save the file as the font "ArmenianLSU-italic" could not be embedded because of licensing restrictions. Turn off the pdf compatibility option and try again." Even if I start a new file I unable to save it with this font. I need to use this font.

Then you need to outline all text before savng the PDF.
Make sure you do this on a copy of the file.

You need to use quotes.

Any more info? It could be many things including what you are doing - you do not "move" anything to the iPhoto library - you use iPhoto (or image capture) to "import" into iPhoto
We know nothing except what you tell us so full information and correct terminology is critical to getting valid answers - the more that is left to one guessing and assuming the better the chance of a bad answer
