How can I get the coordinates to draw a line?

Hi,
I want to draw a line. Here is a part of my Quell-code.
public class Map extends JFrame {
public Map() {
super("Map");
setSize(340, 340);
MapPane map = new MapPane();
getContentPane().add(map);
class MapPane extends JPanel {
public void paintComponent(Graphics comp) {
Graphics2D comp2D = (Graphics2D)comp;
comp2D.drawLine(0,0,340,340);
Now, the line begins exactly top left in the edge, but ends not exactly down right in the edge of my Frame. Is there any possibility to determine the exact coordinates of the frame. I thought, if the size of the window is set by the setSize-Method to (340,340), the line ends exact
in the edge (down right). See: comp2D.drawLine(0,0,340,340).
Can somebody give me a piece of advice, please?
Thanks, joletaxi

Have you tried the getWidth() and getHeoght() methods to determine how long the line should be?

How can I get the coordinate in the layer coordinate system while doing the iterate?

I found that the position(x,y) the iterate function tell me is not right sometimes.
Actually,it happens when the top of the layer is negative. The "y"is in the comp coordinate system(maybe?) but not the layer.In another word, the position with y=0 is not the top.
More specifically, I have got the color map of a layer. I am able to get the color of any pixel in the layer. But I can't set the color one for one when I use "iterate",because there is an offset.
Am I supposed to get the offset? Is there any way to access the whole layer directly if I use iterate function?

so indeed it's the offset at play.
AE will diminish the buffer at 20% increments, and not for each pixel that
goes out of sight. it's not really in relation to the upper left corner,
it's all about what part of your layer buffer is out of sight.
there's also an "iterate offset function". check it out. perhaps it will
save you some trouble.

How can I get the CFL of PO Detail Line?

Hi,Expert
The issue is as the Title.
Apperciate any valuable suggestion.
Regards
Eric Wang

I explain it in detail .I want to get the PO line data by creating the CFL.
The c# code as follows:
        private void AddChooseFromList() {
            try

Shell script: How can i get the parameters of a command line?

Im a newbie. Help please!
For example my mini script test.sh
#!/bin/bash
echo all parameters: $*and now i run some test:
$ ./test.sh aa bb cc
all parameters: aa bb ccok!
$ ./test.sh aa bb $cc
all parameters: aa bbwhere is here $cc ?
$ ./test.sh aa $bb cc
all parameters: aa ccwhere is $bb ?
My question: How can i become 'aa $bb cc'? But without using of \ or ' or " like this:
./test.sh aa \$bb cc
or
./test.sh 'aa $bb cc'Many thanks!

This is exactly what i want! Why not?
It is possible to run a Linux command or bash script from SQLPlus.
It begin with "!" and the script can have parameter too!
You can say:
SQL>!ls
SQL> !ls -l /u01/app
It is possible, also i do it!
My script should have following functions:
- take the SQL statement from SQLPlus as paraameter,
- execute the SQL
- spool the result to a temp file.
- format the select result: elimnate unwanted the column spacing
- present again in SQLPlus
It look like this:
SQL>!do_select_format select * from v$logfile;do_select_format is the name of my script!
and i see somthing like this:
GROUP# STATUS TYPE   MEMBER                                     IS_

How can I get the X and Y coordinates of an object in Xcode, ApplescriptObjc?

How can I get the value of a specified object's X and Y coordinates in Xcode, using ApplescriptObjc? I'm hoping for something like:
myObject's currentPosition()
// Which would return {150, 100} for the X and Y of that object.

Actually this is straight from basic physics
Assuming that the x and y values you get using that AppleScript/Objective-C code is accurate, to move the object you would do
set x to x + dx * speed
set y to y + dx * speed
with dx and dy being an integer with a value of -1 or 1 which indicates the direction the object is moving. Remember the origin in OS X is the middle of the frame or screen with positive x and y values moving to the upper right quadrant, and negative x and y values moving to the lower left. Your basic Cartesian coordinate system. Speed is also an interger and models the speed of the object.
Once you've set x and y to their new values you would write them back to the object.
This is so I can find how much distance (in pixels) is being travelled when I animate an object to move from one position to another, to apply it to my desired velocity (of pixels per second), to find out how long the object should take to move.
This part has got me stumped.
To make an object move you need to change its x and y coordinates. To get smooth animation you need to change them on a regular schedule at a rate fast enough to avoid jerky motion. Given the refresh rate of most monitors and other factors a rate of 60 times per second gives good results. Between each tick of the clock you change the x and y coordinates by some amount, the size of the amount will model speed. Add a small change and the object moves slowly, add a big amount and the object moves quickly. Keep the amount of change constant and the object will move at a constant speed. Increase (or decrease) the amount of change between each tick and the object will accelerate (or decelerate)

How can I get the gps coordinates on my ipad which was stolen today?

My ipad was stolen today, how can I get the gps coordinates to report to the sherriff?

If Find My iPhone (iPad) was turned on on your iPad and the iPad is on and connected to the Internet you will be able to locate it. Go to iCloud.com and sign in with your Apple ID and password. If the device is off or not connected to the Internet you can send a signal to lock or erase the iPad but that action will not complete until the iPad is connected to the Internet.
If you did not have find my iPhone turned on there is no way to track your iPad.

How can I get the direction handles to show up for the Position attribute?

How can I get the direction handles to show up for the Position attribute?
I have CS3 and I did the formentioned test and was able to make the handles work for the scale attribute but they don't seem to show when editing the position values.
*I am in the graph editor looking at the "value graph"
*I select the keys and convert the keys to auto bezier (I also tried the ease in and out buttons)
*It changed the graph the way you might think (no longer linear) however the handles are not showing to edit further.
*I also tried using the "convert vertex tool" (part of the pen tool) and still no luck getting those handles.
*the handles only show up in the speed graph but that does me no good.
Please help!
THANKS

I don't have CS3 installed on any of my machines any more but your value graphs for position should look something like this:
There are no handles for position in the Graph editor. You adjust the position curve by editing the motion path in the composition window. Press the G key to bring up the pen tool, then use the modifier keys Crtl/Cmnd and Alt/Option to temporarily switch between select and convert vertex to adjust the paths. Changes will be reflected in the value graphs. You will get editable handles with scale and rotation because these are not spatial properties. Spatial properties, position, Anchor Point, all XY & Z coordinates are edited in the comp window or in the layer window after revealing the properties. IOW, you edit anchor point position paths by opening up the layer window and choosing Anchor Point from the display options.
The Manual isn't wrong. Here's a link to the live docs.

Hi,
Based on your code, I see your code related to
iTextSharp Pdf.
iText is a third party library to create PDF originally written for java. iTextSharp is
the C# adaptation of that library.
Question regarding iText are better asked on the iText forum, rather than the Microsoft Forum:
http://itextpdf.com/support
Thanks for your understanding.

How can I get the DPI of the current workstation?

Hi can anyone help me?
I want to know the dpi witch is set on a Windows system.
How can i get it? Because i will reformat and fit the dpi of displaying images to the dpi of a current window system, e.g image= 200x200dpi and monitor=84dpi so the dpi of the images should be set to 84.
But How can i get the current dpi of the Workstation?
please help,
florian

yes but it sucks because windows-workstations
manipulates the dpi to a standard value of 96 dpi...
its equal if there is a 15" or a 17" monitor ...
thanks floI agree, getScreenResolution() just doesn't work. Try changing your screen resolution setting (say from 1024x768 to 800x600) and this method will continue to return the same value!
Can one adjust the scale so that you can draw a 1 inch square, for instance? The default affine transform property of the graphics object passed to paint methods is supposed to have 72 units = 1 inch, but that's not true. Again, adjust your screen settings and the same 72x72 square will come out in very different sizes.
Is there any way to correct this, short of going to native code to get the screen resolution? I know that the screen display may be a bit miscallibrated, but anything would be better that the way it is now!

i am having macbook air recently my iphotos did not open and was showing report apple and reopen but i came to know that by pressing alt and iphotos i open an new photo library and stored the pics but now how can i get the pics which i had in the earlier photo please help me to recover my photos

Well I'll guess you're using iPhoto 11:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

How can i get the all values from the Property file to Hashtable?

how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain
8326=sun developer
4306=sun java developer
3943=java developer
how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............

The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is);

Delete the broken links in iTunes then look at your purchased list to redownload.
If this happened because you were deleting files from the iTunes folder in Finder, don't. You have to let iTunes do all the deleting and moving or you will end up with broken links.

Thanks

Since that password is tied to his Apple ID, you will need to contact Apple; as far as I know, it will be a somewhat lengthy procedure and you will need to furnish necessary paperwork (including a death certificate as far as I know). Best to either stop at an Apple store or call them to find out exactly what it is you need to do.
