Question about drawLIne(x1,y1,x2,y2) and repaint()

i am doing this project, which i suppose to use drawLine and repaint() to generate graphs. my problem is, every time i hit a new button it will call the repaint() then my old graph is gone, only the new graph is left.
for example
i have 4 buttons. movesouth() movenorth() moveeast() movewest()
when i hit movesouth two times there should be a staight line, when i hit movewest() my old graph is gone() it only left me with 1 unit to west cuz i have repaint() inside my actionPerformed function, my question is: is there a way that i can redraw these line without calling repaint () ? cuz repaint is kinda like redraw the new stuff and forget about the old ones, however i would like to keep the old one while adding the new graph to it.
your suggestions would be great appreciated.

well of course, your Graphics-Object is of the type Graphics2D, you just need a cast so that the compiler is happy ;-)
Its the same Graphics2D object/instance as withought the cast...

Question about drawLine()

hi all , i just start to learn java, i need help, this almost kill me.....
condition:
a click in the drawing panel indicates the starting point of the line. As the
mouse is moved a line appears between the starting point and the current position of the
mouse. When the mouse is clicked again, the line is frozen in its current position.
my code :
first i create a Line class:
class Line extends Figure {
public Line( int x1, int y1, int x2, int y2 ){
super(x1, y1, x2-x1, y2-y1 ) ;
public void paint(Graphics g) {
super.paint(g);
Dimension size = getSize() ;
g.setColor(Color.blue);
g.drawLine ( 0, 0, size.width-1, size.height-1) ;
then
class DrawingPanel extends JPanel
implements MouseListener,MouseMotionListener, Constants {
static String s ="Circle";
int x1,y1,x2,y2;
DrawingPanel(){
super();
addMouseListener( this );
addMouseMotionListener(this);
public void setMode(String s){
this.s = s;
public void mouseClicked(MouseEvent e) {
Point at = e.getPoint();
if (s.equals("Line")){
x1=at.x;
y1=at.y;
public void mouseMoved(MouseEvent e) {
if( s.equals("Line")){
x2=e.getX();
y2=e.getY();
this.add (new Line(x1,y1,x2,y2));
well , this is part of my code , it do work, but not exactly what i want..

try:
gc.setLineStyle(SWT.LINE_DASH);
gc.setLineWidth(2);
gc.drawLine(....)

Questions about the future directions of InfoPath and Microsoft Access

Because I have been confused about the future directions of InfoPath and Access, I wrote a short blog post, which I have pasted below. My question is, can Microsoft provide some more guidance on Access vs InfoPath? If Access is indeed the
the future direction, can you please provide some pointers to resources that can help us transition.
A Short Review of MS Access, SharePoint ,InfoPath (2013)
After the November 2012 SharePoint Conference in Las Vegas (#spc12) there were a number of blog posts and people saying that Access 2013 was great and would be replacing InfoPath.
Marc Anderson and
Ruven
Gotz have short posts summarizing #SPC12 and touch on the subject of InfoPath and Access. I also spoke with several individuals shortly after #SPC12 and they were excited about Access 2013.
Since I rely heavily on InfoPath for much of what I do, I wanted to kick the tires and see what everyone was talking about. First, a few notes about SharePoint 2013 and Office 2013.
Microsoft should rename Access: If you have tried to
bing the word Access, then you know that the search results are overwhelming, because the word "access" is used for so many other purposes.
Use the RTM version of Office 2013! I was performing my investigations by leveraging the Office 365 Beta and the Office Applications that come with it. Not much was working! After I uninstalled the Beta
version of Office 2013 and Installed the RTM version everything seemed to work.
Windows 7 and IE 9.0: The drag & drop that is being touted as
"manna from heaven" seems to work well with Firefox, Safari, Chrome, and IE 10, but it does
not work with IE 9!
Non Microsoft browsers are still second class citizens (except for the drag & drop): Microsoft has finally done away with the Active X's for datasheet view (that is brilliant!) One can now see the newly
minted datasheet view in many browsers. But I still find that one needs to be in IE to do a number of key manual opeartions. For example pasting numerous rows of data from a spreadsheet into the new sheet view works only in IE.
Access 2013
Microsoft Access is touted as a non developer tool. I know a number of people who are on the business side and love Access. These people will like the renewed energy that Microsoft has applied to Access. One should note that conceptually
this functionality existed in SharePoint 2010. Here is what I see that is new:
+The new version works better:Although I haven't tested it fully, it seems that many more features that work on the Desktop version of Access, now work in the published Web Application which is hosted by SharePoint 2013.
+The new version has fairly robust browser based forms: End users can now fill in data using forms that are rendered in the browser.
+The published version that resides in SharePoint now uses its own SQL server tables. So the engine appears to be SQL Server, not a modified version of Access built for a server. This stands to be quite robust, but I imagine
that some quirks will surface due to new model.
The limitations are:
- Access is pretty much its own application and does not integrate with SharePoint building blocks. For example, an Access table is not easy to integrate with a SharePoint workflow. Further, although Access forms now are visible
in a browser, they are not nearly as rich as InfoPath forms. InfoPath forms cannot easily integrate with the Access tables. In order to integrate SharePoint features and Access, one needs to tie SharePoint list(s) to Access as data sources.
This overcomplicates the model and one may very well run into synchronization issues.
In short, although I believe there will be some people who will be happy with newly minted Access, I do not think that Access will be able to replace InfoPath and Workflow technologies. I do agree that Microsoft does not seem to have put much energy into
InfoPath. If they leave a vacuum in this space, then others may very well take over, for instance Nintex Forms.

Although I agree with the comments made by Ruven and Marc after the conference please note that those blog posts are their own personal opinions and that they don't work for Microsoft. A lot of people have asked Microsoft to clarify the future of InfoPath
and the response up until now has been a deafening silence. In my opinion speculations about Access replacing InfoPath are premature.
I should also point out that most of your comments about Access 2013 above are actually about Access Services in SharePoint Server 2013. Access Services are NOT Access they are a shared service offering in SharePoint that convert and publish Access
databases and forms. As you point out once an Access database is published through Access services it is converted to SQL Server and no longer resides in Access. Of course I don't work for Microsoft either so these are all just my personal opinion.
Having said that I doubt you will get the confirmation/response that you are hoping for from any official Microsoft channel.

But when i do movement type 315, there is a warning message "Data of preceding document was not transmitted", and from the F1 help i find this system reponse "You can maintain an indicator that makes information about preceding documents in this delivery available under delivery type in Customizing. For some characteristics of this indicator, the type of preceding document and the related document and item numbers must be transmitted to delivery creation. At least one of these parameters is missing.".
So, My questions are:

Question About Sharing Apps Between My iPhone and My Wife's iPhone

Hi, I have a question about downloading apps to my iPhone.
I ordered two iPhone 3g's - one for my wife and one for me, and I've discovered that when I download an app (even free ones) on my iPhone and then later sync it to iTunes, my wife cannot put it on her phone. However if I download it on iTunes on my computer and later sync it to my phone, then my wife is able to sync it to her phone as well. It's no big deal when they are free because she can just go get it if she wants it. I haven't purchased any apps yet, but is there a way to be able to give my wife apps that I purchase on my iPhone? Or do I need to purchase all of my [pay] apps and songs on iTunes on my computer to ensure we both have access? Or do I have it all wrong completely LOL?? This rights management stuff is confusing.
Thanks in advance for your help,
Jimmy

I had my iTunes account and phone before I got my wife's hers. When I first started, I synced hers from her account on my computer brought in my libraries and authorized her phone as one of the 5 allowed. She had all purchased apps and music. Over time we each bought music or apps on our seperate accouts. Of course, we told each other about cool apps or music we bought and wanted on our phone. When I went to sync iTunes was going to delete all music and apps and sync with the library I was logged into. Didn't want that, only work around I have found is to copy new music or new apps from one library to the other. Updating on the phone is also difficult because you can't switch between accounts so updates have to be done at the computer for apps bought under different accounts. I am sure there is a better way to do this and ask for an insight anyone would have. I hope it works out.

A Question about Windows games with boot camp and system requirements

I don't plan to play many games on my Mac, but after seeing what can be done with it, I've been entertaining the idea of picking up a Windows game or 2 to play in Boot Camp (considering picking up a XP PRO with SP2 for this).
My question is about the listed systed system requirements and how they might apply to my Mac Pro. I have a dual 2.26.
As a specific example, I was looking at the game Fallout 3. The box lists a 2.4ghz processor required but I've read on this forum about people running it great with less on their Mac.
So I was wondering what I would need to consider when looking at those requirements or if games in that range do indeed run well...

Thanks Kap, you're always helpful.
That's exactly what I was wondering. How the requirement on the box applied to having an 8 core at a lower clock speed.
I was looking at XP home at amazon and newegg, but haven't been able to tell if they are 64 or 32 (unless that means just install that version from the disc).
It's nothing pressing, just something I was entertaining for now.

Questions about Using APIs to import Bills and Routings - AND COSTS

Hi Forum - the following is a back-and-forth with a customer about use of APIs - Inventory developer suggested I post the question here. Note the 2nd question - and thanks for any assistance.
SR# 7332152.994 ALCOA
Instructions given to ct:
Q1 - Can I load the bill header and components at the same time?
You should be able to load the bill header and components at the same time. Customer loads bill and component data inserting enough "other" data for each so that the bill sequence id will be derived. For the component record, the assembly item, org and alternate_bom_designator values will be used by BMCOIN to derive the bill_sequence_id.
Example:
INSERT INTO BOM_BILL_OF_MTLS_INTERFACE
ORGANIZATION_CODE,
ITEM_NUMBER,
ALTERNATE_BOM_DESIGNATOR,
PROCESS_FLAG,
TRANSACTION_TYPE
VALUES
'M1',
'&PARENT_ITEM',
NULL,
'1',
'CREATE'
INSERT INTO BOM_INVENTORY_COMPS_INTERFACE b
ORGANIZATION_CODE,
ASSEMBLY_ITEM_NUMBER,
ALTERNATE_BOM_DESIGNATOR,
COMPONENT_ITEM_NUMBER,
OPERATION_SEQ_NUM,
COMPONENT_QUANTITY,
EFFECTIVITY_DATE,
PROCESS_FLAG,
TRANSACTION_TYPE
VALUES
'M1',
'&PARENT_ITEM',
NULL,
'&COMPONENT_ITEM',
1,
1,
trunc(SYSDATE),
1,
'CREATE'
Hi Aruna, some additional information that may be useful:
We can load/create the bill header and components at the same time using the scripts given (as above)
Required Data for Creating a Routing : assembly_item_id,
organization_id, routing_type, transaction_type, process_flag
And following scripts can be used to load routing header and operations equences.
INSERT INTO BOM_OP_ROUTINGS_INTERFACE
(assembly_item_id,
organization_id,
routing_type,
transaction_type,
process_flag)
VALUES (2255800,207,1,'Create',1);
INSERT INTO BOM_OP_SEQUENCES_INTERFACE
(assembly_item_id,
organization_id,
operation_seq_num,
Department_code,
effectivity_date,
transaction_type,
process_flag,
operation_description)
VALUES
(2255800,207,100,'ASSEMBLY',
to_date('24-FEB-2009'),'Create',1,
'Paint Wagon');
Q2: One more question, can an expense item can be added to the bill and can contribute the cost.
As there is a confusion of what I asked, below I am rephrasing my question
By an Expense Inventory Item, I mean an item that is just tracked for quantity only i.e.,Checking the attributes - Inventory Item, Stockable, Transactable under Inventory Tab and not checking the attribute - 'Inventory Asset Value'.
My question here is, For these Expense Inventory Items, What is the difference between having the 'Costing enabled' attribute turned ON as opposed to having it UNCHECKED
*Q3 I have tried to load the items and I could only load 1st level of components but could not load second level of bom at the same time.
While inserting I have inserted plan level too.
Please let me know if I have to do anything different to load second level.*
Thanks
James

Question about interface for recording electric guitar and vocals

Ok, I've been messing around with Garageband all day, totally stoked and I'm ready to get into it. Right now I'm using a First Act quarter inch plug to USB cord to hook up my guitar and start recording and after some messing around I got it to work.
Here's my question... to really make quality recordings, what's the best way to hook up the guitar? Is the way I'm doing it now fine with the USB cord or is some sort of interface better? Can someone recommend one that's on the cheap side? Also, I haven't tried yet, but what's the best way to record vocals? Should I invest in a USB mic? Can anyone recommend one? I have a Shure SM58 already, what's the best way to hook that up?
Really excited about this, can't wait to start cranking out some songs!
PS: When I use the USB cord, I don't see any way to control the recording level, and sometimes I get a Feedback control warning. How can I lower the level so I don't get that? Thanks!

I have a total now of 4 interfaces - I recently purchased a FOCUSRITE SAPPHIRE 6 USB - it's amazing quality and I only paid $149 for it at my local Guitar Center. I use it with my Guitar and everything sounds fantastic - they say the preamps are really high-quality for Mics too... I recommend it. I have a firewire interface too but the Sapphire is my man baby now - don't let the USB 1.1 fool you - it works flawlessly with my Mac and my Windows 7 machine too. It also comes with a selection of software including Ableton Live Lite and 4 really nice Focusrite plug-ins too.

Question about HP 2311xi - auto-switch source and delay wakeup from sleep

I recently purchased this monitor and noticed that when it wakes from sleep it will take about 5-10 seconds for it to wake whereas other monitors I've owned they have gone on immediately. I was just wondering if this is how this monitor is or if I have an issue with it.
Secondly, how is the auto-switch source suppose to work? I have my PC set to DVI and I have the default source set to my 360 through the HDMI connection. I would assume that when the 360 goes on it would go to the default source and switch over to the hdmi connection. However, my monitor does nothing. What does the auto-switch source actually do or is mine just defective?
Thanks in advance for any help on this monitor.
This question was solved.
View Solution.

Auto-switch source only works if there is no signal as it detects the port with a signal and auto switches to that port. However, the monitor has no way of knowing exactly which port the user wants when two signals are present.
Default port setting is what the monitor will look for first when being turned on and doesn't necessarily give that port override capabilities.
Taking 5-10 seconds can be normal. My third-party monitor at home generally takes about 5 seconds before displaying a signal, but this may have more to do with the HDMI connection (I haven't tested this with the VGA port). I don't believe this is a cause for concern.
Let me know if I answered your questions.

Question about NAT Inside Source, Inside Destination, and Outside Source

I read the Cisco command references about "ip nat inside source", "inside destination", and "outside source", but couldn't have a clear understanding of how to associate the commands with "ip nat inside" and ip nat outside" configured for interfaces.
Does "ip nat inside source ..." translation only happen on the interface configured as "ip nat inside"?
Since NAT is a bidirectional action, what's the difference between "ip nat inside cource ..." and "ip nat inside destination ..."?
I've never used "ip nat outside source ...". In what cases would it be needed?
On an interface where there are NAT translation and also other actions such as policy map or IP Sec crypto map, would NAT happen before or after other actions?
Thanks for help with any questions.

Question about purchasing apple products for government and militairy personel

Hi everybody,
Forgive me if this isn't the right place to start this thread and for my not perfect English language skills :$
My name is Nick and I live in The Netherlands near Amsterdam.
In February i'm traveling to NYC for a 7-day citytrip.
On the internet i read some things about many discounts for militairy personel, including stories from my fellow Dutch soldiers who also got this discount because The Netherlands are allies with the US within the NATO missions in Afghanistan, Iraq and so on.
I am an active soldier in the Dutch Army.
In The Netherlands all Apple products are more expensive then the US products ( because of the Dutch taxes ).
So you understand why i want to buy the Iphone 4S and Ipad 2 in the US.
Now my question is, can I also get the militairy discount from Apple because I am a NATO allied soldier?
Or does this rule only apply on US soldiers?
I hope some one can help me with this issue, because I don't get enough salary to buy Apple products in The Netherlands.
Thanks in advance,
with kind regards,
Nick

Also realize that the prices in many countries appear higher than US prices because they include taxes. Because sales taxes are different in each state & town/city in the US, the price listed on the website for an iPad is less than what you'd actually be paying - and New York City taxes are not cheap (combined state and city is 8.875%) - so a $499 iPad actually costs $543.29. You might have to pay an import duty when you bring the iPad back, and if you don't you could be charged for it when bringing the iPad into an Apple Store for warranty service - I've been told this is true in the UK, for one.

I have two questions about my podcast on iTunes - Image and Author

Hello. I have very recently added my podcast to iTunes, by submitting the RSS-feed that is given by wordpress (that's where I have my podcast homepage) It looks allright, and the feed includes Name of podcast, title of podcast shows, description and in some cases even length of the podcasts. There's two things not showing though, and that's an image for the iTunes page, and the name of the authors.
I'm not sure if you're allowed to link to your feed like this, but here is however the feed that I've sent to iTunes: http://rodrost.wordpress.com/category/podcast/feed/ . I thought that the picture up in the right (of me and a friend) would be the picture showing up on iTunes. And I don't understand where in my feed to put in the authors. If you could answer my questions I would be very grateful, thank you.
/ Joar.
(This is how it looks on iTunes http://itunes.apple.com/se/podcast/rodrost-podcast-podcast/id507886804 )

Posting your feed URL is not only allowed, it's necessary to get answers to most questions, so thank you for posting it.
You are missing some necessary entries in your feed. The second line of your feed should include the 'iTues declaration':
xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"
which should be added within the 'rss' tag. Without this iTunes cannot read the 'itunes:...' tags which are in any case missing. The image is carried in the 'itunes:image' tag and your name in the 'itunes:author' tag, and there are other tags which carry information - your podcast is working without them but some information is as you see missing.
This page includes a sample basic feed so that you can see what I'm talking about:
http://rfwilmut.net/pc
I can't advise on Wordpress: it seems likely that you need the PodPress plugin to get this to work properly, but I'm not sure whether you can do it without.

A question about Logical Disk Performace collection Rules and how the Data is displayed in a Report view

Hello
I am currently on SCOM 2007 R2 CU6 and Window Server Operating System MP version 6.0.6989.0 (I cannot use the latest version of the MP as we still have some Windows 2000 Servers we need to support, yes I know :( )
Any way the issue is, I have never found the Logical Disk performance counter data very reliable from SCOM.
For example, I have a Windows 2008 R2 Server and when looking at a local Logical Disk (which holds an SQL temp DB on a busy SQL Server) and look at the performance counter
The SCOM collection rule is called "Collection Rule for Average Disk Seconds per Transfer"
The actual Windows Perfmon counter is called "Avg. Disk Bytes/Transfer"
if you look at the description of the above Perfmon counter it is described as
"Avg. Disk Bytes/Transfer is the average number of bytes transferred to or from the disk during write or read operations."
The problem I have is as follows:
The resulting SCOM performance chart over several days (which has a scale ox 1x) states the value never reach 3 (e.g. maximum wa s 2.7 say). I cannot believe the a drive holding the tempDB databases for a busy SQL Server does not transfer more then 2.7 "bytes"
of data at a given to to its tempDB databases!
Indeed when I look at Permon on the Server and looks at this counter over say 20 minutes or so, the figure is often in the 10,000 or 30,000 bytes etc. It does fall back to 0 (zero) momentarily but mostly it is in the 1000s, or 10,000s etc.
Therefore when my boss says show me the "Avg. Disk Bytes/Transfer" and SCOM says it has not exceeded 2.7 over the last business week (i.e. the chart never peak above this value on the chart with scale 1x) he naturally does not believe it!!
Any advice please regarding the above. Is it the fact if the counter ever falls to zero it messes up the SCOM report charts?
Thanks

Create your own collection rule, to mirror the sample times, and what not. Look at the data from your rule vs the mp default rule. It probably has to do with the chart scale imho.
