NEED HELP with *.dat files.
How can I create a *.dat file with text in it?
And then how can I read what is in it?
This is kind a urgent so I would appreciate any help..
Thanx in advance...
I'm sure there will be others with more knowledge of such things...
...but one way would be to use RandomAccessReadWriter()

I am printing a calendar and certain events will be helds on certain dates.
One can edit the event if it has not passed the date. Events in the past can be viewed but not edited.
When I query the database the date must be formatted dd-MMM-yy
I am able to get today's date by doing this:
java.util.Date today = new java.util.Date();
String formatString = "dd-MMM-yy";
SimpleDateFormat sdf = new SimpleDateFormat(formatString);
String today_str = sdf.format(today);
My code for printing the calendar: I left out some of the table formatting in the JSP page.
GregorianCalendar d = new GregorianCalendar();
int today = d.get(Calendar.DAY_OF_MONTH);
int month = d.get(Calendar.MONTH);
d.set(Calendar.DAY_OF_MONTH,1);
int weekday = d.get(Calendar.DAY_OF_WEEK);
for(int i = Calendar.SUNDAY; i < weekday; i++)
out.print("<td> </td>");
do {
int day = d.get(Calendar.DAY_OF_MONTH);
out.print("<td>" + day + "</td>");
String formatString = "dd-MMM-yy";
SimpleDateFormat sdf = new SimpleDateFormat(formatString);
//if(event exists on this day
// Get results
// print link for viewing
// if (after today) print link for edit
if(weekday == Calendar.SATURDAY)
out.println("</tr><tr valign=top>");
d.add(Calendar.DAY_OF_MONTH,1);
weekday = d.get(Calendar.DAY_OF_WEEK);
} while(d.get(Calendar.MONTH) == month);
if(weekday != Calendar.SUNDAY)
System.out.println();
The part I need help on is this:
//if(event exists on this day
// Get results
// print link for viewing
// if (after today) print link for edit
I'm looping through each day of the month to print the days. I have the month, day, year as integers. How can I create a date object out of that and compare it to today's date to test if it's before or after today???
All the function in the Date class that I think would do this have been deprecated.Need Help with Dates
Here is some information about dates:
There are many edible palm fruits, and one of the most widespread and favored of these is the data (Phoenix dactylifera). Dates were cultivated in ancient land from Mesopotamia to prehistoric Egypt, possibly as early as 6000 B.C. Then--as now--dates were a staple for the natives of those dry regions. Much later, Arabs spread dates around northern Africa, and dates were introduced into California by the Spaniards in 1765, around Mission San Ignacio.
The date prefers dry, hot climates, because date fruits are injured at temperatures of 20 degrees F, and the damp climate of the California coast was not favorable for fruit production. In the mid-1800s, the date industry developed in California's hot interior valleys and in Arizona. Now the date industry in the United States is localized mostly in the Coachella Valley, where the sandy soils permit the plants to be deeply irrigated. Today the new varieties, mostly introduced in this century, produce about 40 million pounds of dates per annum, or over 60% of the dates consumed in this country. The rest are imported mainly from Persia. According to one survey, about one million people are engaged entirely in date palm cultivation worldwide.
Hope that helps. -
Need help with connecting file inputs to arrays
In this assignment I have a program that will do the following: display a list of names inputed by the user in reverse order, display any names that begin with M or m, and display any names with 5 or more letters. This is all done with arrays.
That was the fun part. The next part requires me to take the names from a Notepad file, them through the arrays and then output them to a second Notepad file.
Here is the original program: (view in full screen so that the code doesn't get jumbled)
import java.io.*; //Imports the Java library
class progB //Defines class
public static void main (String[] arguments) throws IOException
BufferedReader keyboard; //<-
InputStreamReader reader; // Allows the program to
reader = new InputStreamReader (System.in); // read the the keyboard
keyboard = new BufferedReader (reader); //<-
String name; //Assigns the name variable which will be parsed into...
int newnames; //...the integer variable for the amount of names.
int order = 0; //The integer variable that will be used to set the array size
String[] array; //Dynamic array (empty)
System.out.println (" How many names do you want to input?"); //This will get the number that will later define the array
name = keyboard.readLine ();
newnames = Integer.parseInt (name); // Converts the String into the Integer variable
array = new String [newnames]; //This defines the size of the array
DataInput Imp = new DataInputStream (System.in); //Allows data to be input into the array
String temp;
int length; //Defines the length of the array for a loop later on
for (order = 0 ; order < newnames ; order++) //<-
{ // Takes the inputed names and
System.out.println (" Please input name "); // gives them a number according to
temp = keyboard.readLine (); // the order they were inputed in
array [order] = temp; //<-
for (order = newnames - 1 ; order >= 0 ; order--) //<-
{ // Outputs the names in the reverse
System.out.print (" \n "); // order that they were inputed
System.out.println (" Name " + order + " is " + array [order]); //<-
for (order = 0 ; order < newnames ; order++) //<-
if (array [order].startsWith ("M") || array [order].startsWith ("m")) // Finds and outputs any and all
{ // names that begin with M or m
System.out.print (" \n "); //
System.out.println (array [order] + (" starts with M or m")); //
} //<-
for (order = 0 ; order < newnames ; order++) //<-
length = array [order].length (); //
if (length >= 5) // Finds and outputs names
{ // with 5 or more letters
System.out.print (" \n "); //
System.out.println ("Name " + array [order] + " have 5 or more letters "); //<-
}The notepad file contains the following names:
jim
laruie
tim
timothy
manny
joseph
matty
amanda
I have tried various methods but the one thing that really gets me is the fact that i can't find a way to connect the names to the arrays. Opening the file with FileInputStream is easy enough but using the names and then outputing them is quite hard. (unless i'm thinking too hard and there really is a simple method)By "connect", do you just mean you want to put the names into an array?
array[0] = "jim"
array[1] = "laruie"
and so on?
That shouldn't be difficult at all, provided you know how to open a file for reading, and how to read a line of text from it. You can just read the line of text, put it in the array position you want, until the file is exhausted. Then open a file for writing, loop through the array, and write a line.
What part of all that do you need help with? -
Need Help with data type conversion
Hello People,
I am new to java, i need some help with data type conversion:
I have variable(string) storing IP Address
IPAddr="10.10.103.10"
I have to call a library function which passes IP Address and does something and returns me a value.
The problem I have is that external function call in this library excepts IP Address in form of a byte array.
Here is the syntax for the function I am calling through my program
int createDevice (byte[] ipAddress).
now my problem is I don't know how to convert the string IPAddr variable into a byte[] ipAddress to pass it through method.Class InetAddress has a method
byte[] getAddress() You can create an instance using the static method getByName() providing the IP address string as argument. -

I need help with viewing files from the external hard drive on Mac
I own a 2010 mac pro 13' and using OS X 10.9.2(current version). The issue that I am in need of help is with my external hard drive.
I am a photographer so It's safe and convinent to store pictures in my external hard drive.
I have 1TB external hard drive and I've been using for about a year and never dropped it or didn't do any thing to harm the hardware.
Today as always I connected the ext-hard drive to my mac and click on the icon.
All of my pictures and files are gone accept one folder that has program.
So I pulled up the external hard drive's info it says the date is still there, but somehow i can not view them in the finder.
I really need help how to fix this issue!you have a notebook, there is a different forum.
redundancy for files AND backups, and even cloud services
so a reboot with shift key and verify? Recovery mode
but two or more drives.
a backup, a new data drive, a drive for recovery using Data Rescue III
A drive can fail and usually not if, only when
and is it bus powered or not -
hello,
i need to get access to these archives here:
http://rzblx10.uni-regensburg.de/dbinfo … 28#ZEITUNG
for that i need a winframe-client. i got here some help (in german):
http://www.ulb.uni-bonn.de/ebibliothek/ … /index.htm
i tried the wincenter.sh (with hd2u and netkit-rsh) script there and also tried to install the citrix ica-client, but i got nothing working.
has anyone some experience with this stuff?
thank you in advance,
vladWhat you try to do involves a lot of parsing, as others have explained already. Parsing data is a tedious and time consuming task normally, but Labview fortunately offers quite some functions to assist you. Unfortunately, however, one needs some experience to apply them. I assembled a VI (see attachment) which probably comes close to want you want.
When you look into its code you will see some of the parsing techniques. Also notice that I tried to bring the string data from the original file into some other, more useful structure. I do not claim to always have chosen the optimum structure.
Also I did not do any error checking. So I noticed at the end, that some of the data (although contained in the original file) are missing in the summary produced by my VI. The resaon seems to be an inconsistent use of delimiter characters in that file: mostly individual entries are delimited by a series of blank characters, but sometimes an entry is missing (eg. do some of the lines neither contain 'Pass' or 'Fail', but just another blank instead. Since I took a series of consecutive blanks as a delimiter, my counting of entries had to fail.
Try to get a more consistently created raw-data file, e.g. one where tab characters are used as delimiters. Otherwise the parsing will be unnecessarily complicated.
Good luck

Need help with date range searches for Table Sources in SES
Hi all,
I need help, please. I am trying to satisfy a Level 1 client requirement for the ability to search for records in crawled table sources by a date and/or date range. I have performed the following steps, and did not get accurate results from Advanced searching for date. Please help me understand what I am doing wrong, and/or if there is a way to define a date search attribute without creating a LOV for a date column. (My tables have 500,00 rows.)
I am using SES 10.1.8.3 on Windows 32.
My Oracle 10g Spatial Table is called REPORTS and this table has the following columns:
TRACKNUM Varchar2
TITLE Varchar2
SUMMARY CLOB
SYMBOLCODE Varchar2
Timestamp Date
OBSDATE Date
GEOM SDO_GEOMETRY
I set up the REPORTS table source in SES, using TRACKNUM as the Primary Key (unique and not null), and SUMMARY as the CONTENT Column. In the Table Column Mappings I defined TITLE as String and TITLE.
Under Global Settings > Search Attributes I defined a new Search Attribute (type Date) called DATE OCCURRED (DD-MON-YY).
Went back to REPORTS source previously defined and added a new Table Column Mapping - mapping OBSDATE to the newly defined DATE OCCURRED (DD-MON-YY) search attribute.
I then modified the Schedule for the REPORTS source Crawler Policy to “Process All Documents”.
Schedule crawls and indexes entire REPORTS table.
In SES Advanced Search page, I enter my search keyword, select Specific Source Group as REPORTS, select All Match, and used the pick list to select the DATE OCCURRED (DD-MON-YY) Attribute Name, operator of Greater than equal, and entered the Value 01-JAN-07. Then the second attribute name of DATE_OCCURRED (DD-MON-YY), less than equals, 10-JAN-07.
Search results gave me 38,000 documents, and the first 25 I looked at had dates NOT within the 01-JAN-07 / 10-JAN-07 range. (e.g. OBSDATE= 10-MAR-07, 22-SEP-07, 02-FEB-08, etc.)
And, none of the results I opened had ANY dates within the SUMMARY CLOB…in case that’s what was being found in the search.
Can someone help me figure out how to allow my client to search for specific dated records in a db table using a single column for the date? This is a major requirement and they are anxiously awaiting my solution.
Thanks very much, in advance….raford,
Thanks very much for your reply. However, from what I've read in the SES Admin Document is that (I think) the date format DD/MM/YYYY pertains only to searches on "file system" sources (e.g. Word, Excel, Powerpoint, PDF, etc.). We have 3 file system sources among our 25 total sources. The remaining 22 sources are all TABLE or DATABASE sources. The DBA here has done a great job getting the data standardized using the typical/default Oracle DATE type format in our TABLE sources (DD-MON-YY). Our tables have anywhere from 1500 rows to 2 million rows.
I tested your theory that the dates we are entering are being changed to Strings behind the scenes and on the Advanced Page, searched for results using OBSDATE equals 01/02/2007 in an attempt to find data that I know for certain to be in the mapped OBSDATE table column as 01-FEB-07. My result set contained data that had an OBSDATE of 03-MAR-07 and none containing 01-FEB-07.
Here is the big issue...in order for my client to fulfill his primary mission, one of the top 5 requirements is that he/she be able to find specific table rows that are contain a specific date or range of dates.
thanks very much! -
Need help with backup files made by HP Recovery.
So in 2011 I had made a post about a DV9 series HP laptop I had that I felt needed a harddrive. Well the laptop has been sold to a friend of mine and he has since fixed the issue it had. My curent deboggle is trying to deal with the 36GB of data it backed up onto an external USB powered harddrive. The information was saved from a system that ran Windows VISTA, on that same DV9 Pavilion. I have a new laptop and it's a Pavilion DV6 running windows 7. Is there some sort of 3rd party application or an uncommon HP utility that can open, run or modify. Specificaly I need to some files but not all, but if my only option is to extract all then that would be fine also. There is an executible in the backup folder but it doesn't extract anything it just locks up.
For the TLR portion, need to access backup files made on an older HP laptop with windows vista to a newer HP latop running windows 7.Terribly sorry for the post, I should have researched more before posting. I found the answer to my issue in another thread here on the HP forums! Thanks so much!!

Migrating from iMac CD to MBPC2D - Need Help with the FIle Migration
I just ordered a refurb 2.4 MacBook Pro, which will replace my iMac Core Duo as my main machine. The iMac is running Tiger. I've decided that I only am concerned with migrating the following information from the iMac, and want some help on the best way to do this (paths/locations would be helpful too):
-iPhone backups - to ensure my iPhone doesn't get wiped when it syncs. I will want to copy the last backup over to the MBP.
-All iTunes Music and Movies
I will then manually re-install VirusBarrier x4, MS Office, etc. I think this is better than trying to migrate everything over. What do you think?
Edit: I also have a FireWire external hard-drive available to assist with this.
Thanks

Need help with date and time calculations please
Hello there.. Im stuck, and im hoping someone can help..
Working on a list to manage and track PTO. User completes PTO request form,
Fields
Name
Start Date (with time)
End Date (with time)
Total Number of Days/hours requested: (calculation)
Full Day: (Yes/No)
ok business need
user has the ability to request a certain number of hours as opposed to a full day.
After searching around on google. I found this calculation to help me figure out how many BUSINESS days being requested.
=IF(ISERROR(DATEDIF([Start Date],[End Date],"d")),"",(DATEDIF([Start Date],[End Date],"d"))+1-INT(DATEDIF([Start Date],[End Date],"d")/7)*2-IF((WEEKDAY([End Date])-WEEKDAY([Start Date]))<0,2,0)-IF(OR(AND(WEEKDAY([End
Date])=7,WEEKDAY([Start Date])=7),AND(WEEKDAY([End Date])=1,WEEKDAY([Start Date])=1)),1,0)-IF(AND(WEEKDAY([Start Date])=1,(WEEKDAY([End Date])-WEEKDAY([Start Date]))>0),1,0)-IF(AND(NOT(WEEKDAY([Start Date])=7),WEEKDAY([End Date])=7),1,0))
This works great as long as its a [Full Day]="YES", displays results in column labeled Number of days
now if [Full Day]="No", displays results in column labeled Number of Hours
BUT this is my issue (well part of it) it calcuate the correct number of hours.. but puts a "1" in "Number of Days" why.. dates have not changed.. I think Its something with the above calculation but I could be way off.
the end result is I need number of days to concat with number of hours
i.e 1 full day 4 hours 1.4
0 full day 5 hours 0.5
1 full day 0 hours 1.0
so that the total can be deducted via workflow.. from the remaining balance in a tracker. (seperate list)
Any angels out there??Posnera-
