public Myprogram( java.net.URL url ) {
this.url = url;
Thanking you.
Sharon.

Please check the Code snippet and detail the difference

Please go through the two code snippets given below...
Can some one please let me know if using generics is a better way to denote the signature and if yes, why is it so?
Thank you
Two classes:
class SimpleStr {
     String name = "SimpleStr";
     public SimpleStr(String name) {
          this.name = name;
     public String getName() {
          return this.name;
     public String toString() {
          return getName();
class MySimpleStr extends SimpleStr {
     String name = "MySimpleStr";
     public MySimpleStr(String name) {
          super(name);
          this.name = name;
     public String getName() {
          return this.name;
     public String toString() {
          return getName();
Code Snippet 1:
class AnotherSimpleStr {
     public <S extends SimpleStr>S getInfo() {
          return (S)new MySimpleStr("val3");
Code Snippet 2:
class AnotherSimpleStr {
     public SimpleStr getInfo() {
          return new MySimpleStr("val3");
}

Also, please see the code below, the getInfo() method is not taking care of Type safety right??!!!!
class AnotherSimpleStr {
     public <S extends SimpleStr>S getInfo() {
          return (S)new Object();
     public <S extends SimpleStr>S getInfoAgain(Class<S> cls) {
          return (S)new MySimpleStr("Val");
}

Please help me with this error in this code snippet!

Code Snippet:

hi ,
ther is not syntax with clear with 'X".
but you can do one thing to get the one character.

What Is The Difference In The Following Code Snippet?

public class Test12 {
     Test12(){
          Test12();//Compiler Error
and
public class Test12 {
     Test12(){
          new Test12();//Runtime Error after the 1GB of Ram space is used
}Can you please explain as to what is the difference b\w the above code snippet?
Edited by: The_Matrix on Feb 15, 2008 8:19 AM

public class Test12 {
     Test12(){
          Test12();//Compiler Error
}This is not valid because you cannot call a contractor this way. However you can replace it with following code and it will work but it is a infinite recursion.
public class Test12 {
     Test12(){
          this(); // We have now no error. Yahooo...
}The second part of code is also an infinite recursion. I mean following one
public class Test12 {
     Test12(){
          new Test12();//Runtime Error after the 1GB of Ram space is used

Code Snippet - Swipe Gesture to frame or Scene

Using the Timeline Navigation code snippets is real easy to use and understand, I am using the codes to " Click to next scene or frame etc etc and they work fine.
What I dont see in the code snippets is a easy to use " Swipe Gestures" Swipe to frame/ Swipe to Scene/ Swipe to next scene.
Im not a Coder. Everything I have learned is from watchng Lynda.com, Total training and alot of trial and error. When it come to reading long
lines of code my mind goes fritzy. And because of this I have learned to respect you guys who know coding.
I noticed that the you can add your on personal snippets into your library.
I will gladly pay someone to write me a simple Right to left swipe gesture Snippet that lets me navigate to a frame or Scene.
I hope this is something that adobe is planning to add to the Code Snippets Options soon.
Can someone please give me some input on how to make this happen.

What this is ... is a demo for an phone app.
They are doing the demo on a PlayBook.
There are 20 screens and the design looks like a BlackBerry Torch.
The bottom navigation takes the user back to screen One.
I have a button on Frame 1 of the timeline that runs across all 20 screens.
The Code Snippet for that button is:
HomeLeft.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame_9);
function fl_ClickToGoToAndStopAtFrame_9(event:MouseEvent):void
gotoAndStop(1);
So .. if the user is on say ... screen 10 and clicks the "HomeLeft" button .. it takes them to screen #1.
That works.
All the navigation works up to screen 19.
Then ... when you navigate to screen 20 ... nothing.
The buttons react ... but the script is not activated.
I have looked EVERYWHERE for rogue code.
I even deleted the frames for screen 20 and then built it again.
Still ... it does not work.
If I could show you a screen shot of the timeline ... I think it would make more sense.

Serial port control -- what's this code snippet?

Hi, all.
I've just become active working with LabView, version 6.0i. And this because of a program which "suddenly" stopped working, with no changes made by anyone that I can see (yeah, likely story, right?).
In short, the screenshot which I'll include with this post is of one tiny code snippet buried deeply in the .vi which runs an X-Z positioning system. I'd like to know what people thing this code snippet does. I have my suspicions, but I can't believe that whoever wrote this code actually used it for this purpose!
The X- and Z-positioners which I'm using are controlled by separate power sources, and separate ports on the computer. The X-positioner is ultra-fine-resolution, and has an optical encoder. It's controlled by the RS-232 port on the computer, and it's meant to be moved only a little at a time. The Z-positioner is a bit more coarse, and usually moves quite a bit at a time. It's serial-port controlled.
The screenshot is of the portion of the code called "XMove" -- that portion of the code which controls the x-positioning stepper motor. Often, the Z-positioner is still running during this part of the code (the "ZMove" subroutine is called before the "XMove"), and then, after both parts of the positioner have stopped, the code should shut down the power to them, and update the position of the translation stage.
However, once the code gets to this portion (screenshot), that while loop just keeps running.
Here's what I think is happening (please correct me if I'm wrong!): The Z-positioner is run by the serial port, which, as far as I know, can be controlled by only one device at a time. Thus, this While loop does the following:
1) attempts to write the characters "1R" followed by a linefeed to port 0 (the applicable serial port on this computer);
2) reads how many characters are stored in the serial buffer;
3) reads all the characters in the serial buffer;
4) takes the first two characters from the string read;
5) compares these two characters to *R;
6) if the two characters are R, then the loop terminates and the code finishes.
As far as I can tell (I've probed many parts of this structure), the code fails when the "N" portion passes the number of characters in the serial buffer to the "R" portion -- it's always zero. It appears to me that the "W" portion writes to the buffer AFTER the number of characters is read (I wouldn't have suspected this unless I'd run it many times and monitored which steps were done in which order). This ain't right!
I found a similar question answered in the KnowledgeBase forum, but the answer to that one was that the serial port may have an "echo" mode. That doesn't change the fact that data is being from to the port before it's written, does it?
Is there a way to make sure that the "read" statement happens AFTER the "write" statement? Am I way off base with what this code snippet should do? And, most importantly, *** is this a good way to tell if the Z-positioner is done with its job? ***. Is this a standard trick to tell if a program is done with the serial port?
Thanks, all. I know the quandary of trying to debug with so few details, and not having the program in front of you. Any help is appreciated!
Sincerely,
Curtis Osterhoudt

I suspect someone did change it, but they just don't realize they did.
THe code snippet is an example of some very bad LV code! What you suspect is happeneing is indeed true. LV uses a data dependacy paradigm that says code execution order is dependent on data availablility. Data availability is determined by ythe rule that the output of a node or sub-VI is not available until the object completes.
In you snipet, the only node that has to complete before the read bytes at port and the write to port VI is the the constant port number constant. That means that LV can execute either the write or the check bytes at port VI's first. This is determined at LV compile time. If for some reason LV decideds to compile in the write before the check bytes at port, the
n the I/O may work as intended, BUT NOT POROGRAMMED!
For a quick fix, put the contant port number and the write VI in a single frame sequence structure. This way the read from the constant and wire operation must comlplete before the seq completes, therby forcing the read stuff to wait.
I hope this help,

Sharing Code Snippets with team

Does anyone know how to change the Snippets folder to a
shared network folder?
I've had a look in;
C:\Documents and Settings\[username]\Application
Data\Macromedia\Dreamweaver 8\Configuration
and
C:\Program Files\Macromedia\Dreamweaver 8\Configuration
But I'm not entirely sure, I'd like to set up a shared folder
so our team can add/edit and share a code snippet library within

Dreamweaver doesn't support this functionality, even if the
same feature was
already available in Homesite almost 10 years ago.

Working code snippet for JSSE 1.0.2

This code works only with JSSE 1.0.2. JSSE 1.0.1 has a bug I believe which give null cert chain
error when using client authorization.
Below is a java code snippet to create a SSL server and client sockets.
SocketsFactory.java
This class is an utility class which gets you the Secure Socket for server and the client.
It reads from the properties file.
public class SocketsFactory{

          return ctx;
The Server properties file looks like this.
#     Specify the SSL provider here.
#     Using sun's reference implementation for testing..
com.ibm.idmg.ssl.sslProvider=com.sun.net.ssl.internal.ssl.Provider
#     Specify the keystore file that this ssl socket should use
com.ibm.idmg.ssl.keyStore=server.ks
#     Specify the password for this keystore file
com.ibm.idmg.ssl.keyStorePassword=servercanpass
#     Specify the password used to protect the keys in the keystore
#     Note: all the keys should have the same password
com.ibm.idmg.ssl.keyPassword=icanpass
The client properties file
#     Specify the SSL provider here.
#     Using sun's reference implementation for testing..
com.ibm.idmg.ssl.sslProvider=com.sun.net.ssl.internal.ssl.Provider
#     Specify the keystore file that this ssl socket should use
com.ibm.idmg.ssl.keyStore=client.ks
#     Specify the password for this keystore file
com.ibm.idmg.ssl.keyStorePassword=clientshouldpass
#     Specify the password used to protect the keys in the keystore
#     Note: all the keys should have the same password
com.ibm.idmg.ssl.keyPassword=canipass
Now to create the certificates..
Its a 5 step process
1) Create the keystore file.
     keytool -genkey -alias mohan -dname "CN=Mohan Tera OU=IS O=IM L=sanjose S=NY C=US" -keystore server.ks -storepass servercanpass -validity 180 -keypass icanpass
2) Create a self signed certificate. If you need to get it signed from
     verisign then you have to create a certificate request. For testing purposes,
     you can create a self signed certificate.
     keytool -selfcert -alias mohan -dname "CN=Mohan Tera OU=IS O=IM L=sanjose S=NY C=US" -keystore server.ks -storepass servercanpass -validity 180 -keypass icanpass
3) Export the public key from the keystore to a certificate file that is to be imported to the client keystore.
     keytool -export -alias mohan -file fromserver.cer -keystore server.ks -storepass servercanpass
4) Repeat the above steps for the client also..
     a)
     keytool -genkey -alias moks -dname "CN=Jennifer Poda OU=Javasoft O=Sun L=Edison S=NJ C=US" -keystore client.ks -storepass clientshouldpass -validity 180 -keypass canipass
     b)
     keytool -selfcert -alias moks -dname "CN=Jennifer Poda OU=Javasoft O=Sun L=Edison S=NJ C=US" -keystore client.ks -storepass clientshouldpass -validity 180 -keypass canipass
     c)
     keytool -export -alias moks -file fromclient.cer -keystore client.ks -storepass clientshouldpass
5) Import the certificates that were exported in steps 3 and 4c in client and server keystore respectively.
     keytool -import -trustcacerts -alias new -file fromserver.cer -keypass keypass -storepass clientshouldpass -keystore client.ks
     keytool -import -trustcacerts -alias new -file fromclient.cer -keypass keypass -storepass servercanpass -keystore server.ks
And voila you are all set to go..
Hope this explains to all the people who are struggling with JSSE..

Moks

How do I create a drop down menu with Code Snippets and Flash CS5?

Hi
I am wondering how to create a drop down menu using the Code Snippets and CS5?
There are some older tutorials out there and it would be nice if someone could create an updated drop down menu tutorial, and it might be me doing this after I have figured out the best and easiest way to create one, but before that I need some pointers.
Thanks!
Have a great day!
Paal Joachim

You can use panel widget to create manual menu where set to show target on rollover.
Something like this :

OLE2 Doc/Code snippet to assist in creating a word doc with underlined text

I would like to use OLE2 to create a simple Word document. I would like some of the text to be bold/underlined and the rest of the text to be regular. There seems to be a serious dearth of information regarding OLE2 in conjunction with PS/SQL in Word applications. We're running Forms 6 and Oracle 9i.
I don't believe that I need to use the techniques described in the Forms Manual (OLE2 containers, etc.). I have managed to create a Word doc and write some text to it but I've been unable to find out/guess at the syntax that I'd need to control bolding and underlining. It would be a big help if I could just find the syntax for Word OLE2 commands. During my documentation search, I seem to remember a post that mentioned 'Reference 2' and maybe 'Reference 3' as a source of information related to OLE2 in PL/SQL code. If anyone can give me a shove in the right direction I'm more than willing to read the manuals. I won't be too disappointed if someone could send me a code snippet either!
Thanks,
Ron Walker

Hi Ron,
Office ships with a number of resources that you will find indispensable for the sort of work you're doing. Take a look at the VBA IDE (Visual Basic for Applications IDE). You may already be familiar with it, if you've ever written a Word macro, but to call it a macro editor sells it short -- it is a full-blown development environment. Its Object Browser allows you to browse Word's object model, search by keyword, and view call syntax.
In case you aren't familiar with the VBA IDE, try this:
1. Open Word
2. Switch between Word and the VBA IDE by pressing <Alt><F11>
3. Open the Object Browser by pressing <F2>
Spend some time familiarizing yourself with the Object Browser. Constrain its scope by selecting the Word library instead of <All Libraries> (the default). Learn to search by keyword. Click on items within your results for details. If Visual Basic Help is installed, pressing <F1> will raise help on a selected item.
Visual Basic Help may not be part of the Compact or Typical install. Running Office Setup, either from the install CD, or through Add/Remove Programs under Control Panel, will allow you to add the feature. (The Office installer lists Visual Basic Help in the Office Tools section.)
I have found the VBA IDE to be the perfect place for prototyping and testing automated processes. It is a far friendlier environment for learning Office automation, as it offers code completion and context-driven help. Once the process works, I manually translate my VBA routine into Forms PL/SQL, which is fairly painless. I've written a short tutorial, that I will post shortly -- I didn't want to bury it in this thread!
Hope this helps,
