Boolean Array-- Help Plz Urgent
Can i create and initialize an array of booleans like this ?
Boolean[51] Position = true;
Thanks... Plz help
This works:Boolean[] bools = {
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true), new Boolean(true),
new Boolean(true), new Boolean(true), new Boolean(true)
};... and, fortunately, so does this:Boolean[] bools = new Boolean[51];
java.util.Arrays.fill(bools, new Boolean(true));I hope you find this of some help.

Hi,
I want to see Purchase order wise report. The report should show PO wise payment in FI.
PO field is EBLEN and i am unable to find its link to BSIK or BSAK. The reason is that they are not maintaining EBELN in both these table. I tried on LIFNR but LIFNR is for Vendor only and the requirement is for EBELN means in PO.
Please anyone help me out in this regard and also plz tell me any detail tables hierarchy of all modules.
Thanks
Usman Malikhi,
to get payment details w.r.t. PO, you can use the table BSEG, field ZUONR.
this field contains PO number concatenated by item no. Eg: 450001728600020
here 00020 is item no. you can mention BUKRS, GJAHR and SHKZG as 'S' in selection criteria for BSEG. Get the accounting document ' BSEG-BELNR' and BSEG -GJAHR. Concantenate this and input in BSIK-ZUONR to get the required data.
hope it helps. -

"Very Serious threat for N70" Help Plz.Urgent
My Nokia N70 M trinig to call to a unknown no. without my permission.
When I kept my phone idle, after some time phone lights will turn on and it says "In ur account there is no enough balance to call" and 3 beep sound of disconnecting the call.(The message is in my local language) It is just like a message from my network provider.
But I have enough balance and I can call to my local numbers.
Can anyone help??????
It is a virus?????
Give me one answer
Solved!
Go to Solution.Well, it could be a virus, although i never heard of it. Only viruses i know are CommWarrior and Caribe. One of them sends MMS's during night, usually around 4 am and sends the virus via bluetooth during the day.
Anyway, that really seems you have some type of client installed on your phone. i would recommend to save only your important information, format the phone (typing *#7370#) and format your memory card. I'm positive that will be enough.

Help plz~ URGENT: Display image icon with specific coordinates
I want to view an ImageIcon with specific cooridnate (ie, I know the coordinate of the top left hand corner, and i know the height and the width of the "want to display part")
how can i make it such that it will onli view the part i want?
for example
i want to display say from (40, 40) (left hand corner) to (90,90) (right hand corner)
ImageIcon thePic= new ImageIcon("theimage.jpg");
ImageIcon newPic= new ImageIcon( XXXXXXXXX);
what should i put at the XXXXXXXXXX part?
Thanks in advance!Use getSubImage method of BufferedImage. Something like:
Image originalImage = ImageIO.read(imageFile) ;// see ImageIO API
Image scaledImage = originalImage.getScaledInstance(40.40,90,90);
ImageIcon imageIcon = new ImageIcon(scaledImage);ImageIO.read is overloaded for files, inputStreams and URL's so you can choose how to load it.
I'll leave the rest to you

I am using SAXParser:
How to overload startElement, endElement and charcaters method in MyClass. Is that possible because I need three different implementations for all these methods based on the command line options.
thanx in advance!I guees this is a little too late..but a better way is to have a
main class that use three different ContentHandler. this way..you can add more handler with little modification to the code.
eg
public class Example{
int handler; // type of contentHandler to use
public static void main(String args[]){
try{ handler = Integer.parseInt(args[0]) }
catch (NumberFormatException e) { System.err.println(e); }
public void parse(String xmldoc){
ContentHandler chandler;
switch (handler){
case 0: chandler = new myHandler1(currQuery); break;
case 1: chandler = new myHandler2(currQuery); break;
case 2: chandler = new myHandler3(citationList); break;
default: chandler = new myHandler1(currQuery); break;
XMLReader saxReader = XMLReaderFactory.createXMLReader(vendor);
saxReader.setContentHandler(chandler);
InputSource inputSource = new InputSource(new StringReader(xmldoc));
saxReader.parse(inputSource);
public class myHandler1 extends DefaultHandler{
public void startElement(String ns, String name, String qName,
Attributes atts) throws SAXException {
// do something
public void characters(char[] ch, int start, int length) throws
SAXException {
// do something
public void endElement(String ns, String name, String qName) throws

!!!Urgent: Boolean array to number!!!
I am trying to convert boolean array to number but I guess it has some limits. I have a boolean array containing 50 elements I want to convert that into number but it is not happening can anyone help. Its urgent.
The best solution is the one you find it by yourselfIn a hurry I missed it. Let me explain now
1. I tried to convert a boolean array to a number as I had more than 40 elements I was getting only zero because of the limitation of I32 I know that I have to change the representation to 64bit but dont know where to do.
2. Then in the Boolean array to number function when I select the properties there I got the option for changing the representation to 64 bit. (This I totally missed when I was busy searchng a function outside to convert the output to a 64 bit value )
3. Now I got what I expected.

thanx in advanceHi,
Within LSMW, there is an option to write our own code wherein this code can be incorporated.
This is in the Field Mapping Option...
Just go to the Menu Extras->Layout
and click on the check box Form Routines

Here you can define Global Variables and also perform your ABAP Coding.

Please Mark the solution as accepted if your problem is solved and donate kudoes
Solved!
Go to Solution.Hi agar,
values in an array are "assigned" by building an array (using BuildArray) or by replacing values in an existing array (ReplaceArraySubset)!
Good starting point could be this...

Programmatically Cycle through Boolean Array
I'm using an Agilent 34970 with a 34901A switch module. It has 16 switches going to two commons. The end function is to switch through all the sources to read resistance and voltage.
The driver and sample vi from the NI idnet were used as a base for my vi.
The sample vi uses a user-controlled 2-d boolean array (false = open). I want to be able to programmatically cycle through all the switches, but I don't know how to tell the dimensions of array I have.
I would like to go through every element of the 2nd raw for each element in the 1st row. If I could programmatically ignore elements #9, 10, 19, and 20, that would be helpful too.
Thanks for any help!

Is there a way to determine what's in the vi front panel right now? I cannot determine if it's 2x10 or 10x2... There are no properties of the 2-d array that plainly tell me.
There is "array size" which tells you the actual size of the 2D array.
There are properties that tell you how many rows and columns are visible in the front panel array container.
There are also properties that tell which element is currently scrolled to the top left corner.
The size and index position of the front panel array control or indicator is not related to the actual array size. You can show only 2x2 elements of a 1000x1000 array or vice versa. if the container is too big, the extra elements are greyed.

How do you download photo folders from your iphone onto Windows 8?
Windows 8 on my laptop forces me to use the "photo app" and only gives me the options of choosing from photos in my camera roll and not the separate folders I've created on my phone.

Email event limited to certain senders
Is there a way to trigger an email event for only particular senders? I am not sure how the "Scan for text" works, if I can treat it just like a regular expression or use logical operators or anything. I highly doubt it. So is the only way to limi
