Cannot swap symbols at all in CS3?
Flash CS3 on Mac OSX 10.4.11
Extremely simple timeline. Simply want to fade one image to another.
Created a keyframe, added a bitmap, converted it to a symbol, set the alpha of 1st frame to 100%, 2nd frame to 0% & tweened.
Image fades to white -perfect.
Create a new keyframe, set the alpha to 100%, try to swap the symbol to another bitmap I'd converted to a symbol.
Doesn't work.
Inspector always says "instance of symbol 1". Cannot use any other symbols except for this one??
Hoping I'm missing something basic, but I've never seen anything like this happen before.
Here's the code that won't appear in a web browser:

Hi All, I have two questions. First of all my CS3 is saying that it is installed on more than one machine, is there a way of seeing what machines my serial number is registered to? If i want to buy another CS3 serial number how do i go about it? I cannot afford to move to the creative cloud.....
there's no way for you to identify which machines have or had cs3 activated, and you can no longer purchase a cs3 license from adobe.
you can request an activation count reset (Contact Customer Care) and deactivate your cs3 on all your computers. you can then install and activate on up to two computers. -
Please help with cannot find symbol error. Been struggling all day :(
Hi all. :)
Writing a game for my phone with KToolbar and have been getting a cannot find symbol error for every variable and method I try to use across Classes. I've looked all over and though it seems a common problem I always either don't understand or can't get working the various solutions. Example of my errors:
C:\...\BTK800i.java:197: cannot find symbol
symbol : variable youSayWhat
location: class HelloCanvas
youSayWhat=key;
^
If I try BTK800i.variable or BTK800i.message I get a new error.
C:\...\src\BTK800i.java:184: non-static method newOrdersSarge() cannot be referenced from a static context
BTK800i.newOrdersSarge();
^
Both these errors apply to both variables and methods. It only happens when I'm using methods/variables of one class in another, am I using public and private incorrectly? It doesn't seem to make a difference if I make variables public or leave them private, I'm trying to get to them with a public method within a private class. Is it something else? I really have no idea. :(
Here's my code, it's long enough to be a tiresome read so I've tried to skip what I know isn't relevant.
public class BTK800i extends MIDlet {
private Display myDisplay;
private HelloCanvas myCanvas;
public int youSayWhat;
//a whole bunch more skipped here, but I'm fairly certain it's not anything that'll help find a solution
public BTK800i() {
paused=false;
public void startApp() throws MIDletStateChangeException {
if( paused ) {
myCanvas.repaint();
else {
myDisplay=Display.getDisplay(this);
myCanvas=new HelloCanvas();
myDisplay.setCurrent(myCanvas);
myCanvas.setFullScreenMode(true);
youSayWhat=0;
//again with the skipping, more code not related
public void newOrdersSarge() {
//whole bunch of code
//other methods skipped
class HelloCanvas extends Canvas {
public void keyPressed (int key) {
youSayWhat=key;
repaint ();
//skippage
}The stuff I skipped is mainly either more of the same sorta thing or maths/writing to screen stuff.
Thanks alot to anyone who helps. I'm really struggling with this. :(
Dan.But I have been reading them :(
My next-door neighbour unfortunately is an 80-something married man, but I will go have a looksie about static and instances.
I thought the point of public variables was that other classes could use them, is this wrong?
Also does this mean that to use the variables from my BTK class in the HelloCanvas class I need to first instantiate BTK? I don't understand how that works as the code starts running from the BTK class in the first place :S I guess more reading will help with this.
Thanks very much for replying. :)
Edit:
OK I have read up on it but I don't think I found anything I hadn't read before. I tried to make a new class which I could instantiate to hold all the variables and methods I wanted everything to be able to access, but that went disastrously. Am I right in understanding that there are no global variables in Java? :s

1) Please in future use the code tags to format code you post so that it doesn't think you have italics in your code and render it largely1 unreadable. Read this
http://forum.java.sun.com/help.jspa?sec=formatting
2) You commented out the import of java.util which is the problem you are complaining about.
3) Are you planning to stick all the code you ever write into the one source file? Why is all this stuff rammed together. Yoinks. -
Please help. Cannot find symbol Error!
I have been working on this code for days now. It keeps coming up with errors. The error says cannot find symbol. I will bold the areas that say that. I got it down to 23 from 42 but now I have no idea what the problem is. any help is greatly appreciated!! I only added a couple of them mainly because it is overwhelming. I can add the rest of someone replies. Thank you again. Oh and the Classpath is set right. I am compiling from the desktop where I have the file also.

How to export Fw CS3 Symbol Library to Fl CS3 ?
Is it possible to export Symbols created in Fireworks CS3 to
Flash CS3 Professional witout losing their properties?Curt
>Just to be clear CS4 you see some, but not all keywords, or in CS4 you see no keywords?<
I've made more sense of the problem. It's to do with Olympus Raw files - .orf. I've been shooting in Olympus camera raw since 2004.
My workflow is: import the raw files into Bridge via a card reader; rename them in Bridge as [filename].ORF, apply keywords, edit them in Adobe Camera Raw, save them as [filename].PSD (or sometimes .TIF or .JPG), move the PSDs to a working folder, edit them in Photoshop, and finally move them to a 'Finals' folder.
In Bridge CS3, in my old computer, I can see all keywords for ORF files. I can also see all keywords for the working and final PSDs, TIFs and JPGs.
In Bridge CS4, in my new computer, I cannot see any keywords for ORF files, or for the working and final PSDs, etc.
I can only see keywords for files which started life as TIFs - photos scanned with my negative scanner or flatbed scanner.
This is also true in both Bridge CS3 and Bridge CS4 in my new laptop, which is running XP Pro. I could see the keywords in my old laptop, but not in my new one.
>If you right click on file info in Bridge do you have the keyword listed in keyword box? Do the same with Windows Explorer and see if keyword is listed in Properties/details.<
'Keyword' isn't listed in Windows Explorer, though everything else under the sun is.
The keywords are listed if I right click in Bridge CS3 on a file in my old computer. And if I click on Advanced, and expand the categories, e.g. XMP or Dublin Core Props, I get a heading 'xap:Keywords (bag container)', and a list of all the keywords attached to the file.
But the same file in CS3 in the laptop, or CS4 in laptop or new computer, has no keywords in Advanced.
I've had a quick look on the web for topics connected with Olympus camera raw/orf/losing keywords, but so far haven't found anything.

Getting error message Cannot Resolve Symbol when trying to compile a class

I am using Sun JDK Version 1.3.0_02" and Apache/Tomcat 4.0. Both the calling and the called class are in the same directory.
Any help would be greatly appreciated.
tnx..
addiIs ConnectionPool in this "cal" package as well as PooledConnection? From the directory you are compiling from it appears that it is. If it is, then you are compiling it incorrectly. To compile ConnectionPool (and PooledConnection similarly), you must change the current directory to the one that contains cal and type
javac cal/ConnectionPool. -
How do i transfer a symbol library from .ai cs3 to cs6
how do i transfer a symbol library from .ai cs3 to cs6
You could just copy the ai file to the new folder. All custom symbol libraries are just ai files.
But since CS3 9-slice guides were introduced, so you might want to check your symbols first (if the guides might be applied or if they are correctly not applied - whatever is appropriate) -
Issue with - "cannot find symbol - variable JOptionPane"

Class error - cannot resolve symbol "MyDocumentListener"

this is a groaner I'm sure, but I don't see the problem.

Qusay -
I am having a "Cannot find symbol" problem. My Java is a bit rusty so I'm not exactly sure what it could be. I have two classes, City and SisterCities. The SisterCities references the City class. The City class compiles fine. Both classes are part of the same package. However, when I compile SisterCities, I get the error. Could you please tell me how to get the second class to recognize the first (import, extends, not really sure. I've tried alot) Here are those two classes so far...
****** City ********
package hw01;
public class City
public final String name;
public final String country;
public final City [] sisters;
public City (String name, String country)
// throw new RuntimeException ("Not implemented yet.");
this.name = name;
this.country = country;
this.sisters = new City [0];
public City (String name, String country, City [] sisters)
// throw new RuntimeException ("Not implemented yet.");
this.name = name;
this.country = country;
this.sisters = new City [sisters.length];
for (int i = 0; i < sisters.length; i++) {
this.sisters[i] = sisters;
public void setSisters (City [] sisters)
// throw new RuntimeException ("Not implemented yet.");
for (int i = 0; i < sisters.length; i++) {
this.sisters[i] = sisters[i];
public String getName ()
// throw new RuntimeException ("Not implemented yet.");
return this.name;
public String getCountry ()
// throw new RuntimeException ("Not implemented yet.");
return this.country;
public City [] getSisters ()
// throw new RuntimeException ("Not implemented yet.");
return this.sisters;
******** SisterCities *********
package hw01;
import java.util.LinkedList;
public class SisterCities
public final LinkedList cityList;
public SisterCities ()
// throw new RuntimeException ("Not implemented yet.");
public void addCity (City city)
// throw new RuntimeException ("Not implemented yet.");
this.cityList.add(city);
public int getNumCities ()
// throw new RuntimeException ("Not implemented yet.");
public City getCity (int i)
// throw new RuntimeException ("Not implemented yet.");final attribute members like "cityList" must be initialised when they're declared or inside the constructors
if you want to compile, you'll also have to uncomment the "throws" in your methods (or return a value)
(pay attention to the error messages the compiler gives you and paste them all when posting questions) -

Scanner keyboard = new Scanner(System.in);generates an error with my compiler:
cannot find symbol class Scanner
please helpyou aren't using jdk 5 or higher then. that's when scanner was added to the jdk.

VijuActually, you have NO CLUE what he's trying to doActually he said what he is trying to do in his posting. It's no mystery. But that's all the information that's available. If you know something that isn't posted here why not say so?
Your reply was a snide, rude, "You're stupid for doing it that way" answerMy reply was neither snide nor rude and implied none of what you impute to it. It was a proper and constructive suggestion. You are entitled to disagree with it, but that doesn't justify this immoderate outburst.
Bottom line is, you chose to be nastyBottom line is you're just making this up. You are imputing motives to me without evidence. Don't do that.
You are the type of person that makes searching forums and posting questions for assistance a near waste of time.I doubt that you'll find many regulars here that would agree with that assertion. When you have made over 16,000 posts here over ten years as I have, come back and we'll discuss it some more.
Go back to grade school and ...I suggest you try it yourself. You're not adding anything except noise to the discussion. Try curbing your temper, and while you're at it have a good look at the Code of Conduct for these forums. You're verging on personal abuse here.
And, additionally, I've used ANT in the past. Batch files are FAR AND AWAY easier to set up.In your opinion. I disagree entirely, and I have eleven years' experience with Java to back it up.
As for CLASSPATH, I haven't done anything about setting it beyond installing the JDK since about 1999, and it has a dot in it as we speak. -
"cannot find symbol" error - password checker class
I had to make a program to check a password to make sure it had two letters, at least eight characters, and only numbers and letters. I'm pretty sure I have all of the checking correct but I can't make use of the method I made to do it. here is my code:
if(password.LegalPassword())
System.out.println("You enterend a valid password!");
else
System.out.println("You have entered an invalid password!");
class LegitPassword
//constructor
public LegitPassword(String userPassword)
public boolean LegalPassword (String userPassword)
int digitCounter = 0;
for(int i = 0; i < userPassword.length(); i++)
//is character a letter or number?
if(!(Character.isDigit(userPassword.charAt(i))) || !(Character.isLetter(userPassword.charAt(i))))
return false;
//is the password at least 8 characters?
if(userPassword.length() <= 8)
return false;
//count the digits
if(Character.isDigit(userPassword.charAt(i)))
digitCounter ++;
if(digitCounter <= 2)
return false;
return true;
}oh, and the exact error is:
PasswordChecker.java:27: cannot find symbol
symbol : method LegalPassword()
location: class java.lang.String
if(password.LegalPassword())
^Here is the full code so that you can see how I declared password...
public class PasswordChecker
static Scanner console = new Scanner(System.in);
public static void main(String[] args)
String password;
System.out.println("Please enter a new password.");
System.out.println("Remember: Passwords must be at least eight characters"
+ " consisting of only numbers and letters with at minimal two numbers.");
System.out.print("Password: ");
password = console.nextLine();
//LegitPassword thePassword = new LegitPassword(password);
if(password.LegalPassword())
System.out.println("You enterend a valid password!");
