I need a method for ignoring empty lines

Hi to all,
i need a method for ignoring empty lines when my program reades a file like that
start of file
print "xoxox"
//ignore this line
println"xaxaxa"
//ignore this line
end of file
cheers

Are you having trouble detecting these empty lines? Or are you having trouble not processing them once you've detected them?
For the first case, you neeed to define "empty." I assumed it meant "containing no characters," and that's what the first solution shows. Your example looks like "empty" means "starts with comment characters."
For the second case, you ignore them by just not doing anything: read a line
if (it is not empty) { // by whatever criteria you define for "empty"
do something with it
}

This is possible. You can schedule a Archive job for perticular devices to run periodically, like every 6 hours, daily, weekly or monthly.

Need a method for importing Palm III data into a Palm Centro

I just bought a Palm Centro (Verizon), with the expectation of importing data from my old Palm III. From the Palm III Desktop, I exported Contacts, Calendar, Tasks, and Memos into separate folders (this was done on a Windows XP PC) and copied the resulting folders & files onto a flash drive. But when I try to import these files into the Palm Centro desktop (on a new Mac Pro with OSX), the backup files are not in a "recognized format." Does anyone have a process for reliably getting the Palm III data into the Palm Centro? Also, is there an easy way to purge unwanted Contacts/Calendar events from the Palm Centro handheld? With all the trial and error, its accumulating a lot of garbage. Thanks...
Post relates to: Centro (Verizon)

Click on the following link for the upgrade guide on kb.palm.com
http://www.palm.com/cgi-bin/cso_kbURL.cgi?ID=12926
You will need to hard reset the Centro in order to clear out the Centro before sync'ing. Click on the following link for the hard reset procedure.

Click on the following link for the support page for your devices on the kb.palm.com webpage.

http://www.palm.com/us/support/palm3/
There are links on the pages to the user guide, troubleshooting, how to's, downloads, etc.
You could try to export the data in each category in Palm desktop, save to the flash drive and import the data.
Click here for the data export procedure.

Make sure you select "ALL" for the range during the export procedure. If you don't, it will only export the currently selected record.

Empty line handling in sender fileadapter FCC

Hi Al,
How do we ignore empty lines in the fixed length file by using FCC?
In my input file,i would be having emply lines at last and as per my curect FCC configurations,it is reading that emplty line also and due to this,message got failed in message mapping.How do we ignore this in sender file adapter?
I do not want to change any mapping condition.

Hi Rajesh,
Just a short in the dark . There is a parameter by the name of NameA.keepIncompleteFields
This parameter is only evaluated if you enter a value for NameA.fieldFixedLengths.
○ If you enter NO and the last field found in the structure is shorter than specified in NameA.fieldFixedLengths, processing is terminated with a corresponding error message.This is the default.
○ If you enter YES, the last field found in the inbound structure is transferred to the outbound structure, even if it is shorter than specified in NameA.fieldFixedLengths.
Caution
You use this parameter to control the behavior of the conversion routine for the last field in a structure.
Use the NameA.missingLastFields parameter to define the behavior at runtime when the structure contains less fields or no fields (as in your case a blank line) in total that specified in NameA.fieldFixedLengths.

SAPScript - controlled empty Line

Hello,
I have a Problem in a Sapscript: in den MAIN, between all items, we need to print an empty line to separate the items. The problem is, if at the end of the MAIN, after an item they is not enough space for this empty line, this line is printed automatically at the begining of the next new page. I want to avoid this empty line at the end of page. Is this possible?
I have make test with "Protect" and "Endprotect", it's works but in this case, the new page is trigged and the complete last item of the page is printed at the next page. This is not a good solution because we lost to much place at the end of the MAIN.
Is any other solution possible? It is possible to controll this empty line?
Thanks for answer.

Hi SaiRam,
I have already try this, i think it's the same solution as yours and it doesn't work:
(For the test, the empty line is replaced by variable, that's shows the page numers)
/: DEFINE &SAV_PAGE& := 1
/: IF &SAV_PAGE& NE &NEXTPAGE&
/: &SAV_PAGE& = &NEXTPAGE&
/: ENDIF.
/: IF &PAGE& EQ &SAV_PAGE&.
page = &PAGE&, nextpage = &NEXTPAGE&, save = &SAV_PAGE&
/: ENDIF.
Here an example of the result:
Item 10
page = 1, nextpage = 2, save = 1
Item 20
page = 1, nextpage = 2, save = 1
Item 30
page = 1, nextpage = 2, save = 2
Item 70
End-Of-Page
New-Page
page = 2, nextpage = 3, save = 1
Item 80
Item 90
Item 100
We see that the system doesn't have enough place after "item 70" to print the Page-Line, so it trigged a new page. Normaly, he doesn't have to print the Page-Line at the bottom of the line, but it doesn't work. I don't know how avoid the print of this line at the bottom of a page. On a New-Page, i wan't start the Print with an item-line and not with a Page-Line.
Have I do something wrong?
Thanks for your answer.

When I open up an e-mail attachment a box pops up PRINT TO FILE below that line OUTPUT FILE NAME with an empty line for the file name vs. simply going to my default printer?

when I open up an e-mail attachment a box pops up PRINT TO FILE below that line OUTPUT FILE NAME with an empty line for the file name vs. simply going to my default printer?

Make sure that '''''Print to File''''' isn't selected in the native print dialog box ''(see screenshot below)'' middle-right, and make sure your Printer is selected at the top of that dialog box.
''I'm a little confused why an email attachment would need to go directly to the printer, but that's what you asked about.''

Create a NEW account using these instructions. Make sure you follow the instructions. Many do not and if you do not you will not get the None option. You must use an email address that you have not used with Apple before.

Using those instructions you may also be able to select PayPal if that is allowed in your country.

Can SAP ignore blank lines in Excel when uploading the planning for PCA?

Hi,
We have launch planning on PCA in SAP. We are uploading the planning figures from an Excel-sheet via the standard function in SAP. The problem is that sometimes we get blank lines in the Excel-doc. When we upload with blank lines we receive an error. Can I somehow get SAP to ignore blank lines?
Best regards
Carl-Johan

Well you can delete the empty lines in excel using the sort functionality and try it.
Hope it helps..

Need help finding the default payment method for supplier site in R12

I am using the following query to find out what the default payment method is for a supplier site.
select pv.vendor_id ,
pvs.vendor_site_id,
iepa.ext_payee_id,
ieppm.payment_method_code
from ap_supplier_sites_all pvs
,ap_suppliers pv
,iby_external_payees_all iepa
,iby_ext_party_pmt_mthds ieppm
where pv.pay_group_lookup_code = 'EMPLOYEE'
and pv.vendor_type_lookup_code = 'EMPLOYEE'
and pv.employee_id is not null
and pv.employee_id =92584--p_person_id
and pv.vendor_id= pvs.vendor_id

and iepa.ext_payee_id = ieppm.ext_pmt_party_id
and ieppm.primary_flag = 'Y'
and pv.segment1 = '131678'
The problem is that I am returning two rows.
I have gone in to the application and changed the default payment method from 'Check' to 'Electronic' and I am able to see the change on one of the records, however I am unable to determine how I'm supposed to narrow it down to just this record. I am pulling what hair I have left out!
Please help.

Need to know the best method for pattern matching

Hi,
I need a best a way to do the pattern matching with better performance
for the following requirement.
i need to search for a set of records as per the following requirements.
1. The input string will be split into tokens with space as delimiter
so if the user enters the text 'severe head ache',the tokens formed will be
severe
head
ache
2. The terms which contain exact match of the tokens formed should be fetched from the database
(i.e)
i. the token should appear in the term as such and no alpha-numeric character should be appended to it but a single space or any single non alpha-numeric characer is allowed
ii. the token may occur anywhere in the string.(like start, end, middle etc.)
iii. the term should contain all the tokens
For ex. the following terms will be fetched for the above input
1. patient has severe head ache
2. severe, head ache are present
3. leg pain "severe" #head pain
4. pain, severe in head, leg
But following terms should not be fetched
1. severe leg pain - (it does not have the token 'head')
2. headache severe and leg pain - (head is a part of the word headache)
3. head67 severe pain - (head is a part of the word head67)
Thanks

Please Help : i need a RETR(download) method for FTP

Hello everyone !!
İ want to write ftpClient class to connect ftp server.i complete the some of the methods of the class.For example; in the following there is a upload method (stor )... i works fine !!
Can u help the modify this method for downloading ( in ftp protocol = retr)
I am not good enough in file operations..Please help me !!!
public synchronized boolean stor(File file) throws IOException {
if (file.isDirectory()) {
throw new IOException("SimpleFTP cannot upload a directory.");
String filename = file.getName();
return stor(new FileInputStream(file), filename);
* Sends a file to be stored on the FTP server.
* Returns true if the file transfer was successful.
* The file is sent in passive mode to avoid NAT or firewall problems
* at the client end.
public synchronized boolean stor(InputStream inputStream, String filename) throws IOException {
BufferedInputStream input = new BufferedInputStream(inputStream);
sendLine("PASV");
String response = readLine();
if (!response.startsWith("227 ")) {
throw new IOException("SimpleFTP could not request passive mode: " + response);
String ip = null;
int port = -1;
int opening = response.indexOf('(');
int closing = response.indexOf(')', opening + 1);
if (closing > 0) {
String dataLink = response.substring(opening + 1, closing);
StringTokenizer tokenizer = new StringTokenizer(dataLink, ",");
try {
ip = tokenizer.nextToken() + "." + tokenizer.nextToken() + "." + tokenizer.nextToken() + "." + tokenizer.nextToken();
port = Integer.parseInt(tokenizer.nextToken()) * 256 + Integer.parseInt(tokenizer.nextToken());
catch (Exception e) {
throw new IOException("SimpleFTP received bad data link information: " + response);
sendLine("STOR " + filename);
Socket dataSocket = new Socket(ip, port);
response = readLine();
if (!response.startsWith("150 ")) {
throw new IOException("SimpleFTP was not allowed to send the file: " + response);
BufferedOutputStream output = new BufferedOutputStream(dataSocket.getOutputStream()) ;
byte[] buffer = new byte[4096];
int bytesRead = 0;
while ((bytesRead = input.read(buffer)) != -1) {
output.write(buffer, 0, bytesRead);
output.flush();
output.close();
input.close();
response = readLine();
return response.startsWith("226 ");
}

Rather than fixing the code, may I ask why, when you are admittedly not good at Java I/O, you are trying to write an FTP client? Such things exist already and are free for your use.
