Hi Everyone, I am using iPhone5, my question in how to display name and contact number both stored for incoming and outgoing calls? If I have saved five different numbers with a same name, how do I recognise that from which number caller is calling?
I have friends all over Europe, does it matter what number they use to call me? Nope! All incoming calls are free for me.
The only time you ever have to worry about which number is if you get charged for incoming domestic/international calls.
You can tag their number (work/home/iphone) and that may show on the CallerID accordingly.
It should show, John Doe
underneath, work/home/mobile
For example:

How to set up and test the Basic Authentication for HTTP protocol
Hi,
I tried configuring the password based Basic Authentication for sending xml document using ebMS - HTTP protocol. I set username and password while configuring the transport server for both trading partners. I want to know, is that sufficient for basic authenticaton. When I open the URI http://localhost:7778/b2b/transportServlet, it is not asking any authentication (username/password). Please note that I have not used SSL certificate. Anyone please help me out to configure Basic authentication.Hi Ramesh,
Thanks for ur response. Could you please tell me where to set the Additional Transport header : authtype-basic#realm=myRealm(in which property file). In enqueue code, I could see the following attributes
queue
msgID
replyToMsgID
from
to
eventName
doctypeName
doctypeRevision
msgType
payload
attachment
subscriber
Is it possible to set username/password in the enqueue attributes?
Do i need to add username/password and Transport header in the input XML and defined that elements in xsd? -
HOw Do I count and identify the number of groups in a groups output.
I have a query that reads like this..
SELECT s.spec_Sort,s.spec_ID, s.spec_Name, b.bus_Name,
b.bus_ID
FROM (tbl_businesses as b INNER JOIN tbl_SpecBusRel as sb ON
b.bus_ID = sb.specbus_busid) INNER JOIN tbl_specialties as s ON
sb.specbus_specid = s.spec_ID
ORDER BY s.spec_Sort, b.bus_Name
and then I am outputing like this...
<cfoutput query="rsGetSpecialties" group="spec_Name">
<cfif THIS IS WHAT I
NEED)></td><td></cfif>
<h2><a class="specialty" href="javascript;"
onclick="dwfaq_ToggleOMaticDisplay(this,'#spec_ID#');return
document.MM_returnValue">#spec_Name#</a></h2>
<div id="#spec_ID#" style="display:none">
<cfoutput><p><a
href="#request.details#?bus_ID=#bus_ID#">#bus_Name#</a></p></cfoutput>
</div>
</cfoutput>
This displays in this manner...
Specialty
dealer
Specialty
dealer1
dealer2
Etc...
What I am trying to do is find out how many specialties there
are, figure out where the middle is so I can insert a new table
data cell and start a new column.
Basically - two columns with the data divided in half by
specialty NOT by the number of dealers.
I hope that makes sense. Of course I am trying to do it w/ as
little query action as possible. My only solution may be to have
more than one query and the second only finds a list of the
sepcialties that contain the dealers and then find the middle one
and simply say if current specialty = middleSpecialty then start a
new column.
Thanks all,
ChrisThanks for the replies. I don't need the number of occurances
of each specialties - I simply need to know how many specialties
there are and then split them in half.
This may be the long way around -but it is what I did...
<cfquery name="rsGetSpecialties" >
SELECT s.spec_Sort,s.spec_ID, s.spec_Name, b.bus_Name,
b.bus_ID, b.bus_Pcity, b.bus_PState
FROM (tbl_businesses as b INNER JOIN tbl_SpecBusRel as sb ON
b.bus_ID = sb.specbus_busid) INNER JOIN tbl_specialties as s ON
sb.specbus_specid = s.spec_ID
ORDER BY s.spec_Sort, b.bus_Name
</cfquery>
<cfset specs = valuelist(rsGetSpecialties.spec_ID)>
<cfquery name="rsListSpecialties">
SELECT spec_ID,spec_Name
FROM tbl_specialties
WHERE spec_ID in(#specs#)
ORDER BY spec_Name
</cfquery>
<cfset middle = int(rsListSpecialties.recordcount/2)>
<cfset specs = valuelist(rsListSpecialties.spec_Name)>
<cfset middle = listgetat(#specs#,middle)>
then displayed like this...
<td valign="top" width="50%">
<cfoutput query="rsGetSpecialties" group="spec_Name">
<h2><a class="specialty" href="javascript;"
onclick="dwfaq_ToggleOMaticDisplay(this,'#spec_ID#');return
document.MM_returnValue">#spec_Name#</a></h2>
<div id="#spec_ID#" style="display:none">
<cfoutput><a
href="#request.details#?bus_ID=#bus_ID#">#bus_Name#
(#bus_PCity#, #bus_PState#)</a><br /></cfoutput>
</div>
*****This is the line that does the splitting *****
<cfif spec_Name EQ middle></td><td
valign="top" width="50%"></cfif>
</cfoutput>
</td>
As for removing the extraneous cfoutput --> I thought that
I needed that in order to show the material within the grouped
data. HOw does CF know what data to repeat and what data to not
repeat in a grouped output? I will have to look this one up some
more.
thanks for the help -
How To: Identifyin​g and locating the correct driver for your device
I have a Toshiba L50-A and recently had a problem with my Brother mfc-J220 printer, could not print anything. I first tried to download the drivers for my Brother printer device but didn't work. I was told it was because there was a missing driver in my Toshiba laptop related to printers?, but cannot see where I might be able to download these. Another person mentioned I should re format my Toshiba back to factory set and I would be able to recover these drivers?
Help! :-) could someone give me a "heads up " with this please?

How can i pull the payment transactions for each invoice?
Hi folks
iam developing report for following requirement.
want to disply the vendor transaction file for all company codes Fiscal year,of 2004,2005,2006, and 2007 (to date).
The purpose of oureport is to analyze our company invoices and investigate potential overpayment opportunities. In order to effectively accomplish this, we need a single invoice record for each invoice that was received by compnay from their vendors. The single invoice record would contain at least the following columns: Vendor Number, Vendor Invoice Number, Invoice Date, Invoice Amount, SAP Document Number, Check/Wire Number, Check/Wire Date, Check/Wire Amount. SAP would have multiple rows in a table for any one invoice, whereas we would only want to see ONE row for every vendor invoice.
if you know that company pays (for example) 75,000 invoices/year - then the transaction file you would have about 300,000 records in it. 75,000 Invoices * 4 years.
inodrer to develop this report iam using table PAYR -payee
BSIK ( closed items) BSAK ( open items).
my question is any one tell me how can write logic to pull the payment transactions for each invoice?
regards
neeruHi rob,
yes you are right, an invovice may contaion duplicate records
example PAYR table contain
invice no compnay code checkno vendor fisclyear
( doc.number)
2000134373 001 10287200 2007
2000134373 001 10427890 2007
so as per my requirement how can i write the logic.

Getting the first row for each group
Hi Everyone,
I have a query which returns a number of rows, all of which are valid. What I need to do is to get the first row for each group and work with those records.
For example ...
client flight startairport destairport stops
A fl123 LGW BKK 2
A fl124 LHR BKK 5
B fl432 LGW XYZ 7
B fl432 MAN ABC 8
.... etc.
I would need to return one row for Client A and one row for Client B (etc.) but find that I can't use the MIN function because it would return the MIN value for each column (i.e. mix up the rows). I also can use the rownum=1 because this would only return one row rather than one row per group (i.e. per client).
I have been investigating and most postings seem to say that it needs a second query to look up the first row for each grouping. This is a solution which would not really be practical because my query is already quite complex and incorporating duplicate subqueries would just make the whole thing much to cumbersome.
So what I really new is a "MIN by group" or a "TOP by group" or a "ROWNUM=1 by group" function.
Can anyone help me with this? I'm sure that there must be a command to handle this.
Regards and any thanks,
Alan Searle
Cologne, GermanySomething like this:
select *
from (
select table1.*
row_number() over (partition by col1, col2 order by col3, col4) rn
from table1
where rn = 1In the "partition by" clause you place what you normally would "group by".
In the "order by" clause you define which will have row_number = 1.
Edit:
PS. The [url http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/functions004.htm#i81407]docs have more examples on using analytical functions ;-)

How can identify the default currency for a customer?
How can identify the default currency for a customer?
I know that this is being determined when you create a sales order for a particular customer, for example, so I could break this process open and find out what it uses. But I thought it worth asking in this forum first.
BlueHi Gary,
As per my understanding of your question I am replying , If you are looking some thing else then I request you to please elaborate your query.
If you see the BP sales area data in transaction BP, In billing tab you maintain the currency for a customer which is default currency when you create a sales order.

Need information for how to Capture, Transmit, and Identify a DTMF tone
Hello every body
I would like to implements the DTMF where i need some information that hoe i can
1) Capture the tone mean when i press button 'one' it has to capture and generate a vaoice file.
2) And i need to transmit the same thing to a remote system.
3) At the remote system how i can reveive and identify that the tone is for 'one'.
Thanks to ............. in advance
Sreenath KulkarniJMF isn't the right tool - it's about handling media streams
You could use it to capture the audio source, then obtain the audio samples,
But you would then have to perfom some signal processing on it to interpret/decode for tone detection
This is what should already be available via the JTAPI API (haven't checked but should do this sort of thing)
ie you should be able to code up an application that receives 'DTMF Tone' events & does whatever you need to do in response
This is what IVR systems do -

On Demand doesn't support adding attachments via web services. One
solution I've seen is depending on the scenario is to create a web link
field on an object that's based on a custom text field. Your web service
can populate that custom field and the web link can generate a dynamic
link to the file in On Demand's UI. However, this depends on where the
attachment is located and if the user needs some sort of firewall access.
Hope this helps

I have multiple iPhoto libraries w/ duplicates in several. How can I consolidate and find the dupes? Some photos are versions of the original. On my iMac, I also have many folders containing some of the same photos. My computer is used for both personal and business purposes. My libraries should be separated, one for each.
To merge libraries use iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ - or Aperature
To find duplicates within an iPhoto library use iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ -
Photos that are not in an iPhoto library can be imported telling iPhoto not to import duplicates (an imperfect procews) and then IPLM can find the duplicates
As to keeping seperate libraries - only you can do that - IPLM can move photos between libraries for you but only you can know which photos should be in which library
