Help with ABS
Hi. 2 days ago, I managed to setup photoshop cs4 runing on wine, but suddenly it stopped working today when after system upgrade. I noticed that wine version changed, so I searched on wiki to find how to get previous versions. Now... I found article on ABS, so I copied wine folder from abs tree, to my home/my username/abs directory. In wine pkgbuild I found in copied directory, I modified version to 1.2.2 which is last stable as I read on winehq. When I go to abs/wine and run makepkg -s I get this:
==> Making package: wine 1.2.2-1 (Sat Feb 5 15:37:06 CET 2011)
==> Checking Runtime Dependencies...
==> Checking Buildtime Dependencies...
==> Retrieving Sources...
-> Found wine-1.2.2.tar.bz2
==> Validating source files with md5sums...
wine-1.2.2.tar.bz2 ... FAILED
==> ERROR: One or more files did not pass the validity check!
Anyway, I thought that abs is created so that I can get source from some completely unknown software, and, I don't know.., compile it and make some sort of installation script for arch, and this is same as downloading from aur and running makepkg -si. Am I getting something wrong? Because, I've allready downloaded source from winehq, so I was kind of disappointed. I expected that I'll have to put this source into abs/wine folder and then do something with it.
Any ideas how to make this work? Here's PKGBUILD:

EDIT: Just to make a note. I uninstalled official wine version with pacman and removed .wine from my home. And btw, I'm seeing this md5 checksums all over the web lately, so I'm guessing it's some way to check weather package is corrupted or not? If someone can explane me how can I check package with md5checksum in addition, that would be cool.
EDIT: One more thing. It says in wiki "now you just need to build that from source..." does that mean I have tounpack tar I just got from running makepkg -s and run install script?

You didn't want to use the ABS, you wanted to downgrade the Wine package. I expect you may still downgrade without too much trouble.
You should use this wiki article as your guide: https://wiki.archlinux.org/index.php/Do … g_Packages

An md5sum is an integrity check to ensure that copies of a file match the original file. You can easily Google for linux howtos.
An ABS pkgbuild contains md5sums for the files in the current Arch version of the software. The md5sums should not match previous versions of the software. The files are not the same.
If you have problems downgrading Wine, others will help, I'm sure.
Thank you, you're awesome. I'm using linux for about 3.5 weeks now, and I never would have thought that there would be something like A.R.M. Now I can test those wine versions to see with which photoshop work best. Linux is awesome! XD (had to say that, but can't say arch explicitly, cos I haven't tried other versions )

New to Arch,
I'm trying to wrap my head around abs and aur. I understand having to make the files, but I'm not sure where to put the url's for the mirrors I want to DL from, such as github, I read the guide and put them in the files and it kept saying they were invalid. It's confusing me alot. I understand this is probably a dumb question but if someone could point me to the correct information I would greatly appreciate it. The guides I found didn't get me through it.
EDIT: I reread the wiki and the man pages, I was following a guide I found which got me more and more confused, from now on I'll ensure the hostname is archlinux.org before following a guide so closely

Need help with calculator project for an assignment...
Hi all, I please need help with my calculator project that I have to do for an assignment.
Here is the project's specifications that I need to do"
"""Create a console calculator applicaion that:
* Takes one command line argument: your name and surname. When the
program starts, display the date and time with a welcome message for the
user.
* Display all the available options to the user. Your calculator must include
the arithmetic operations as well as at least five scientific operations of the
Math class.
-Your program must also have the ability to round a number and
truncate it.
-When you multiply by 2, you should not use the '*' operator to perform the
operation.
-Your program must also be able to reverse the sign of a number.
* Include sufficient error checking in your program to ensure that the user
only enters valid input. Make use of the String; Character, and other
wrapper classes to help you.
* Your program must be able to do conversions between decimal, octal and
hex numbers.
* Make use of a menu. You should give the user the option to end the
program when entering a certain option.
* When the program exits, display a message for the user, stating the
current time, and calculate and display how long the user used your
program.
* Make use of helper classes where possible.
* Use the SDK to run your program."""
When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??
Here is the programs code that I've written so far:

What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
AND you might want to ask yourself why the heck a calculator needs to know the users Name. -

Hello. I am somewhat new to Java and I was recently assigned to do a simple paint program. I have had no trouble up until my class started getting into the graphical functions of Java. I need help with my program. I am supposed to start off with a program that draws lines and changes a minimum of 5 colors.

}If anyone could point me in the right direction of how to go about getting my buttons to work and fixing the button box, I would be greatly appreciative. I just need to get a little bit of advice and I think I should be good after I get this going.
Thanks.This isn't in any way a complete solution, but I'm posting code for a mouse drag outliner. This may be preferable to how you are doing rectangles right now

}1) Swing related questions should be posted in the Swing forum.
Custom painting should be done in the paintComponent(..) method. You created a "pintarGraphico" method to do the custom painting, but that method is only execute once. When Java determines that the panel needs to be repainted, the paintComponent() method is executed which simply does a super.paintComponent(), which in turn simply paints the background of the panel overwriting you custom painting. -
Help with eclipse Qt4 pkgbuild [solved]
Hello!
I want to use qt integration with eclipse.
I looked in Aur and found a pkgbuild but he is out of date so I decided to modify it and
I would like to ask someone to look at it to be sure I did a right job.
I always fear to kill permission when I play with abs
The pkgbuild:
# Contributor: Alex Rodin <[email protected]>
# Contributor: Shaika-Dzari <[email protected]>
pkgname=eclipse-qt4
pkgver=1.0.1
pkgrel=1
pkgdesc="Qt4 integration for Eclipse"

md5sums=('d01ad9bc4cd953340b9db806f49dac8f')
build()
mkdir -p $startdir/pkg/usr/share/eclipse
cp -R $startdir/src/eclipse/plugins $startdir/pkg/usr/share/eclipse
mkdir -p $startdir/pkg/usr/share/licenses/$pkgname
cp $startdir/src/eclipse/features/com.trolltech.qtcpp.feature_1.0.1/license.txt $startdir/pkg/usr/share/licenses/$pkgname/COPYNG
I changed:
* new version 1.0.1
* new download url
* switch to /usr/share for eclipse plugins
Thank you for your help.

I am a rookie and need help with max and min values
Hello all, i am into this intro to java class. my assignment is to write a program that prompts the user for two integers and then prints the sum, difference, average, product , distance (absolute value of the difference) Maximum(largest of the two) and Minimum(smallest fo the two) here is my code so far
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.lang.Math;
public class Sample4
public static void main(String[] args) throws IOException
try // attempt the following
{ // create the stream to read from
InputStreamReader istream = new InputStreamReader(System.in); // create a buffer to hold the stream
BufferedReader console = new BufferedReader(istream); // prompt the user
System.out.println("Enter a number please"); // get input as a string
String input = console.readLine(); // convert to an integer
int num1 = Integer.parseInt(input);
System.out.println("Enter a number please"); // get input as a string
String input2 = console.readLine(); // convert to an integer
int num2 = Integer.parseInt(input2);
int sum = num1 + num2; // get the sum of the two inputs
int difference = num1 - num2; // get the difference of the two inputs
int product = num1 * num2; // get the product of the two inputs
int average = sum / 2; // get the average of the two inputs
int abs = Math.abs(difference); // get the absolute value of the two inputs
// new section
// display the number
System.out.println("The total sum = " + sum);
System.out.println("The total difference = " + difference);
System.out.println("The total product = " + product);
System.out.println("The total average = " + average);
System.out.println("The total absolute value = " + abs);
} // if something breaks, catch the exception
catch (IOException e)
System.out.println(e); // displays the exception
System.exit(1); // quits the program
}what will be the right syntax or code to find the MAX and MIN values of two numbers a User Inputs, hope someone can help with this. thank you for your help.Thanks alot man, sheesh i do not know why my book
doesnt give me all the static methods. but i do really
appreciate your help. peaceA complete list of the java.lang.Math methods can be found at http://java.sun.com/j2se/1.4/docs/api/java/lang/Math.html
btw,
max(a, b) == (a > b) ? a : b
min(a, b) == (a < b) ? a : b -
Help with if statement in cursor and for loop to get output
I have the following cursor and and want to use if else statement to get the output. The cursor is working fine. What i need help with is how to use and if else statement to only get the folderrsn that have not been updated in the last 30 days. If you look at the talbe below my select statement is showing folderrs 291631 was updated only 4 days ago and folderrsn 322160 was also updated 4 days ago.
I do not want these two to appear in my result set. So i need to use if else so that my result only shows all folderrsn that havenot been updated in the last 30 days.
Here is my cursor:
/*Cursor for Email procedure. It is working Shows userid and the string
You need to update these folders*/
DECLARE
a_user varchar2(200) := null;
v_assigneduser varchar2(20);
v_folderrsn varchar2(200);
v_emailaddress varchar2(60);
v_subject varchar2(200);
Cursor c IS
SELECT assigneduser, vu.emailaddress, f.folderrsn, trunc(f.indate) AS "IN DATE",
MAX (trunc(fpa.attemptdate)) AS "LAST UPDATE",

Hoping for some help with a very frustrating issue!
I have been syncing calendar and contacts on my iPhone 5 and Outlook 2007 using iCloud 2.1.3 (my PC is running Vista). All was well until the events I entered on the phone were showing up in Outlook, but not the other way around. I’ve tried the usual recommended steps: deselecting calendar and contacts in the iCloud control panel and then re-selecting, signing out of the panel and back in, and repairing the Outlook installation in control panel. I even uninstalled iCloud on the PC and downloaded it again (same version).
The furthest I’ve gotten is step 2 (and once, step 3) of 7 while performing “Outlook Setup For iCloud.” At that point I get, “Your setup couldn’t be started because of an unexpected error.” After the first attempt at all this, all my calendar events disappeared from Outlook, although they are still in iCloud calendar and on my phone.
Sound familiar? Any ideas on how to solve this iCloud/Outlook issue? Thanks much in advance!Hoping for some help with a very frustrating issue!

Help with HP Laser Printer 1200se
HP Support Line,
Really need your assistance. I have tried both contacting HP by phone (told they no longer support our printer via phone help), the tech told me that I needed to contact HP by e-mail for assistance. I then sent an e-mail for assistance and got that reply today, the reply is as follows "Randall, unfortunately, HP does not offer support via e-mail for your product. However many resources are available on the HP web site that may provide the answer to your inquiry. Support is also available via telephone. A list of technical support numbers can be round at the following URL........." The phone numbers listed are the ones I called and the ones that told me I needed to contact the e-mail support for help.
So here I am looking for your help with my issue.
We just bought a new HP Pavillion Slimline Desk Top PC (as our 6 year old HP Pavillion PC died on us). We have 2 HP printers, one (an all-in-one type printer, used maily for copying and printing color, when needed) is connected and it is working fine with the exception of the scanning option (not supported by Windows 7). However we use our Laser Printer for all of our regular prining needs. This is the HP LaserPrinter 1200se, which is about 6 years old but works really well. For this printer we currently only have a parallel connection type cord and there is not a parallel port on the Slimline HP PC. The printer also has the option to connedt a USB cable (we do not currently have this type of cable).
We posed the following two questions:
1. Is the Laser Jet 1200se compatible with Windows 7?
and if this is the case
2. Can we purchase either a) a USC connection cord (generic or do we need a printer specific cord)? or b) is there there a printer cable converter adapater to attach to our parallel cable to convert to a USB connection?
We do not want to purchase the USB cable if Windows 7 will not accept the connection, or if doing this will harm the PC.
We really would appreciate any assitance that you might give us.
Thank you,
Randy and Leslie GibsonSorry, both cannot be enabled by design. That said, devices on a network do not care how others are connected. You can print from a wireless connection to a wired (Ethernet) printer and v/v.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

Going to Australia and need help with Power converters
Facts:
US uses 110v on 60hz
Australia 220v on 50hz
Making sure I understood that correctly. Devices I plan on bringing that will use power are PS3 Slim, MacBook Pro 2008 model, and WD 1TB External HDD. My DS, and Cell are charging via USB to save trouble of other cables.
Ideas I've had or thought of:
1. Get a power converter for a US Powerstrip, and then plug in my US items into the strip and then the strip into an AUS Converter into Australian outlet. Not sure if this fixes the voltage/frequency change.
2. Get power converters for all my devices. But, not sure if my devices needs ways of lowering the voltage/increasing frequency or something to help with the adjustment.
3. Buy a universal powerstrip, which is extremely costly and I wouldn't be able to have here in time (I leave Thursday). Unless Best Buy carrys one.godzillafan868 wrote:

Check the specs on input voltage/frequency of your power supplies.
Many laptop power supplies are "universal/global" and are specced something like 80-265 volts AC 50/60 Hz, but not all. These will just need a connector adapter.
Unsure about the PS3 Slim - if it isn't universal it could be difficult as you'll need a 110/220 transformer, one big enough (power-handling wise) for the PS3 will be very bulky.
For the external WD HDD, if it doesn't have a universal supply, you're probably best off just finding a new wallwart for it that is capable of running on 220/50.

Creation of context sensitive help with pure FM 12 usage doesn't work
Hi,
I hope somebody is able to help me with a good hint or tip.
I am trying to create a context-sensitive Microsoft Help with FM12 only using the abilities of FM (no RoboHelp). For some reasons, my assigned ID's are not used in the generated chm file and therefore the help does not work context-sensitively.
What did I do?
- I created my FM files and assigned topic aliases to the headers. I did this two ways: a) using the "Special" menue and assigning a CSH marker and/or b) setting a new marker of type "Topic Alias" and typing the ID. I used only numeric IDs like "2000" or "4200",
- I created a .h file (projectname.h) - based on the format of the file projectname_!Generated!.h (I read this in some instructions). So the .h file (text file) looks like this:
#define 2000 2000 /* 4 Anwendungsoberfläche */
#define 2022 2022 /* 4.1.1 Menü Datei */
#define 2030 2030 /* 4.1.3 Menü Parametersatz */
#define 2180 2180 /* 6.6.7 Objektdialog Q-Regler */
#define 2354 2354 /* 6.9.2 Objektdialog Extran Parameter */
#define 2560 2560 /* 6.9.5 Objektdialog Extran2D Parametersatz */
- I published the Microsoft HTML Help. A projectname_!Generated!.h has been created. My IDs were not used in this file:
#define 2000 1
#define 2022 2
#define 2030 3
#define 2180 4
#define 2354 5
#define 2560 6
- When I open the .chm file and look in the source code, the ID even is totally different. It is not the one, I assigned in FM, it is not the one which I assigned in the projectname.h file and it even is not the one, which was put in the projectname_!Generated!.h file. It is a generated name starting with CSH_1 ...n in a consecutive way numbered.
Example:
<p class="FM_Heading1"><a name="XREF_72066_13_Glossar"></a>Gloss<a name="CSH_1"></a>ar</p>
What goes wrong? Why does FM not take my assigned IDs? I need to use these IDs since our programmers are using those already - I had to re-create the whole online help but the programs stay untouched.
Please help!
Many thanks
MohiHi Jeff,
thanks for your note!
The text in my marker is just a number like "2000" or "4200". As said, I created manually a my.h file and used this marker there. E.g.
#define 2000 2000.
Whereby the first 2000 (in my opinion) is the marker text and the second 2000 is the context ID which the programmers are using for the context sensitive call of the help. My definitions in the my.h file were translated to #define 2000 1 (in the my_!Generated!.h file). The source code "translates" the context ID into CSH_8.
I am still confused :-/
Thanks
Mohi
