How do i make my public ip static?
Hello. I host a server for me and my friends to mplay on. When ever i unplug the router or the power goes out, my ip changes. Is there a way to make my ip stay the same so i dont have to tell my friends the new one? Thanks.
Call Comcast and ask for a static IP address. They will be happy to provide one for $19.95/month, or a block of 5 addresses for $24.95/month.

How do I make dynamic text look static while the HMTL tagging is enabled?
Hi all,
I am using flash 8 with AS 2.0.
I have a dynamic text field where I am setting it's text value through a variable. Now, I need this dynamic text field content to look like static font on runtime. I tried embedding the text field but that makes my file so heavy and most importantly, it disables the HTML tagging on the text field.
Please suggest me on how to make a dynamic text field content look static on runtime while the HTML tagging is enabled and working fine.
Thanks.I am sorry. But the attachment was not intended for what you
thought my friend.
It was there so that there are no confusions for what I mean by look of dynamic and static text fields. -
How do I make a clipping mask static?
I have a group of objects that move around within a 700x500 px artboard. The size of one object within this group is a map that spills over outside the artboard. I want this group to only be 400 px high, but not change anything withing the group. Just shorten the height of the clip. When I tried to just clip the height to 400 the clipping obviously followed the zooming of the animation of the group. I want the hight to be static at 400 when the animation plays.
Any ideas? Do I need a second clipping mask like I would have added if I worked in Illustrator? So I could move a whole group within a static clipping mask. If so, how do I create one?"1) remove the clip set to the group"
How? When I mark the group and then click on clipping tool (only why I know to mark the clipping mask) I can´t delete it without deleting the entire group.
"2) use style="overflow:hidden" instead of use style="overflow:visible"
But that´s on the stage? It´s already set at hidden there. I don´t want to change the height of the stage. -
How to create website on iweb and make it public, and tell me how to put a password on it.
Hi, can you tell me how to create website on iweb and make it public, and tell me how to put a password on it, thanks.
Find a webhosting company :

They will provide the instructions how to password protect a directory (=folder)?
Until you find one, you can practice on your own computer :

How To Make A Public Page Parameter (similar to session)
Hi, I'm new to Oracle Portal
I wonder how to make a public parameter that can be accessed from any page (similar to session).
So the portlets can use the public parameter.
Case:
when user logged in, I pass the employee_ID to the session.
Portal pages, which contains employee portlet, and some other portlet depends on employee_ID.
So I think, may be there's a way to set the parameter for once, but the value is accessible until the user log off.
Any suggestion or help?
Thx before,
ChrisLet me explain the problem once again:
Page 1 Portlet 1 contains employee table
ID, Name, Address
When I click the employee ID (using event), it will be pass the value to page parameter EMPID
And i want this EMPID can be accessed by
Portlet 2 - Showing sales report
Portlet 3 - Showing report
Portlet 4 - Showing chart
Portlet 5
and so on
Portlet 2, 3 4, 5, and so on is using EMPID as the parameter too,
but these portlets are located in different page
Portlet 2 is in page 2
Portlet 3 is in page 3
Portlet 4 is in page 4
Portlet 5 is in page 5
and so on
First I think about using Package wwpro_api_parameters
but after read further, this package can get and retrieve only
I wonder can this (public page parameter) be done by using default Oracle Portal Tools / API, or I should do some java coding, or something else?
Please help me...
Thanx before,
Chris -
How to javadoc "public final static int"?
How can we create "Field Summary" HTML document for "public final static int" variables?
This question is probably same as the below question.
http://forums.java.sun.com/thread.jsp?forum=41&thread=72832
p.s.
The below document indicates CENTER, NORTH, ...
How an we achieve it to document "public final static" variables?
http://java.sun.com/products/jdk/1.2/docs/api/index.htmlNo, 1.3 does not have the static constant values exposed to the Doclet API,
and so that information is not available to any doclets to place in the
generated documentation.
BTW, based on feedback from a developer, we changed the format from:
public static final int NORTH = 0
to
public static final int NORTH
See: Constant values
where the "Constant values" link takes them to a summary page that
lists all of the values. This helps discourage users from mistakenly
seeing and using the value instead of the constant.

How to make page public / non public with api
I need to turn some pages to be public or non-public (the same as the tick box on the access page) using plsql. But the API's wwsec_api.set_user_acl or wwsec_api.set_group_acl do not seem to work for public. How can I a page public or non public using plsql.
supported solution for doing this is using wwsbr_api.modify_folder(p_page => p_page);
(from version 10.1.4)
you should have something like this
SELECT *
INTO r_page
FROM wwv_user_corners
WHERE siteid = p_pgrid
AND id = p_pageID
AND language = p_portal_lang;
r_page.ispublic := 1;
wwsbr_api.modify_folder(p_page => p_page); -
How can I make the combo box turn to the value of black.
When the show button is pressed (and not before), a filled black square should be
displayed in the display area. The combo box (or drop down list) that enables the user to choose the colour of
the displayed shape and the altering should take effect immediately.When the show button is pressed,
the image should immediately revert to the black square, the combo box should show the value that
correspond to the black.
Now ,the problem is: after I pressed show button, the image is reverted to the black square,but I don't know
how can I make the combo box turn to the value of black.
Any help or hint?Thanks a lot!

How do you make an array of image icons and then call them?
How do you make an array of image icons and then call them, i have searched all over the internet for making an array of icons, but i have
found nothing. Below is my attempt at making an array of icons, but i cant seem to make it work. Basically, i want the image to match the value of the roll of the dice (rollVal)
Any help would be greatly appreciated, some code or link to tuturial, ect.

How can I make ANY vector graphics with graphics2D and save on clipboard?
I am at my wits end here, and need some help. Simply put, I have a program that creates a basic x-y graph, drawn in a jpanel. I want to create the graph as a vector (emf, eps, svg, I don't care anymore, any of them would be good). But, all I get is a jpg or bitmap.
I tried using the infamous FreeHEP programs, but it won't recognize the output as anything but "image" which means bitmap/jpg.
The user enters x/y data, clicks a button, which crreates a jpanel thusly:
public class GraphMaker extends JPanel {
static BufferedImage image = new BufferedImage(600, 500, BufferedImage.TYPE_INT_ARGB);
GraphMaker(double[] xVals, double[] yVals, double[] sems){
setPreferredSize(new Dimension (600,500));
symSize = 10;
XminV = 0;
XmaxV = 0;
// code here just converts input x and y's to pixel coordinates, spacing of ticks, etc...
for (int i =0;i < ArLn; i++){
gX[i] = xO + (gX[i] * xRat);
gX[i] -= xStart;
gY[i] = gY[i] * yRat;
gY[i] = yEnd - gY;
semVal[i] = semVal[i]*yRat;
Ymin = yEnd - (Ymin*yRat);
Ymax = yEnd - (Ymax*yRat);
BufferedImage anImage = new BufferedImage(600, 500, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = anImage.createGraphics();
g2.setBackground(white);
g2.setColor( Color.WHITE );
g2.fillRect(0,0,600,500);
g2.setStroke(stroke);
// here I use the values to draw lines and circles - nothing spectacular:
g2.setPaint(Color.blue);
int ii = 0;
for ( int j = 0; j < ArLn[ii]; j++ ) {
g2.fill(new Ellipse2D.Float(LgX[ii][j] - symOffst, gY[ii][j]-symOffst, symSize,symSize));
g2.draw(new Line2D.Float(LgX[ii][j],(gY[ii][j]-semVal[ii][j]),LgX[ii][j],(gY[ii][j]+semVal[ii][j])));
g2.draw(new Line2D.Float(LgX[ii][j]-2.0f,(gY[ii][j]-semVal[ii][j]),LgX[ii][j]+2.0f,(gY[ii][j]-semVal[ii][j])));
g2.draw(new Line2D.Float(LgX[ii][j]-2.0f,(gY[ii][j]+semVal[ii][j]),LgX[ii][j]+2.0f,(gY[ii][j]+semVal[ii][j])));
g2.draw(new Line2D.Float(xLoVal[ii],yLoVal[ii],xHiVal[ii],yHiVal[ii]));
image = anImage;
And, when the user clicks on the "copy" button, invokes this:
public class Freep implements Transferable, ClipboardOwner {
public static final DataFlavor POSTSCRIPT_FLAVOR = new DataFlavor("application/postscript", "Postscript");
private static DataFlavor[] supportedFlavors = {
DataFlavor.imageFlavor,
POSTSCRIPT_FLAVOR,
DataFlavor.stringFlavor
private static JPanel chart;
private int width;
private int height;
public Freep(JPanel theGraph, int width, int height) {
this.theGraph = Graphs;
this.width = width;
this.height = height;
//******This is the key method right here: It is ALWAYS imageFlavor, never anything else. How do I make this an EPS flavor?
public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException, IOException {
if (flavor.equals(DataFlavor.imageFlavor)) {
return GraphMaker.image;
else if (flavor.equals(POSTSCRIPT_FLAVOR)) {
return new ByteArrayInputStream(epsOutputStream().toByteArray());
else if (flavor.equals(DataFlavor.stringFlavor)) {
return epsOutputStream().toString();
} else{
throw new UnsupportedFlavorException(flavor);
private ByteArrayOutputStream epsOutputStream() throws IOException {
EPSDocumentGraphics2D g2d = new EPSDocumentGraphics2D(false);
g2d.setGraphicContext(new org.apache.xmlgraphics.java2d.GraphicContext());
ByteArrayOutputStream out = new ByteArrayOutputStream();
public DataFlavor[] getTransferDataFlavors() {
return supportedFlavors;
public boolean isDataFlavorSupported(DataFlavor flavor) {
for(DataFlavor f : supportedFlavors) {
if (f.equals(flavor))
return true;
return false;
public void lostOwnership(Clipboard arg, Transferable arg1) {
The same happens with FreeHEP - I want the flavor to be EMF, but the program sees an image so it is always imageFlavor. I know I am missing something, but what, I don't know.
thanks for your help.I don't think there's a built-in solution. One workaround I've seen is to create a dummy graphics class that overrides the desired drawing functions. Instead of actually drawing pixels, the object writes postscript commands to a buffer. There also seems to be commercial code that does exactly this.
