Variable names "{name}" showing up before dataset loads
I am using an XML dataset. I have it working perfectly except
for the fact that on the page in question, right before the data
loads, you see the actual variable names writeen out on the page.
Also as part of my data, i am displaying an image, so until the
data loads there is a broken image and then it loads. Is there a
way to handle this so the variables dont show until the data
loads?

New tabs are not updating the names of the sites they have loaded. When I open a new tab and load a site, the tab simply stays named "New Tab". When I open a link in a new window, it shows "Connecting..." even while its fully loaded.
This issue can be caused by an extension that isn't working properly.

How can I specify the PARTITION name at the time of data load?
Hi,
I have a table with 4 partitions. By using SQL*Loader I'm going to load data into the same. While inserting the records it should go to the 2nd partition only.
Where should i specify the Partition name?
Please clarify me with sample code.
Thanks.Assuming that the partition is empty before the load, I would load the data into a temp table with the same structure as the partitioned table. After all the data is successfully loaded, exchange the partition of the table with the temp table using 'alter table ... exchange partition...'
Another question is, how is your table partitioned?

Using variable coulmn name in sql function
Hi there,
I am not an expert with PL/SQL and I can not figure out how to use variable column names in my function.
My function is:
CREATE OR REPLACE FUNCTION RESET_TRIGGERS(aTrigger VARCHAR2) RETURN NUMBER IS
TEMP_ID NUMBER;
TEMP_USER_ID NUMBER;
BEGIN
SELECT 'LIMS.'||'$aTrigger'||'.NEXTVAL' INTO TEMP_ID FROM DUAL;
SELECT 'LIMS.'||'$aTrigger'||'_USER.NEXTVAL' INTO TEMP_USER_ID FROM DUAL;
IF TEMP_ID > TEMP_USER_ID THEN
LOOP
SELECT LIMS.SQ_U_FINALRESULT_USER.NEXTVAL INTO TEMP_USER_ID FROM DUAL;
EXIT WHEN TEMP_USER_ID = TEMP_ID;
END LOOP;
ELSE
WHILE TEMP_ID < TEMP_USER_ID LOOP
SELECT LIMS.SQ_U_FINALRESULT.NEXTVAL INTO TEMP_ID FROM DUAL;
END LOOP;
END IF;
COMMIT;
RETURN (TEMP_ID);
END;
What I want is that I pass a seqencename with aTrigger and that two triggers will be equal if not.
eg ifaTrigger = 'SQ_U_FINALRESULT'
than I want the triggers LIMS.SQ_U_FINALRESULT and LIMS.SQ_U_FINALRESULT_USER to be set equal.
The above function will not work, but what will?????
I hope you can help me out!
CheersA very strange function indeed.
But here is what I think he meant to do:
SQL> create procedure reset_sequences
2 ( p_sequence_name in varchar2
3 , p_nextval out number
4 )
5 is
6 l_nextval1 number;
7 l_nextval2 number
8 ;
9 procedure reset_sequence_value
10 ( p_sequence_name in varchar2
11 , p_current_value in number
12 , p_new_value in number
13 )
14 is
15 l_dummy number;
16 begin
17 execute immediate 'alter sequence ' || p_sequence_name || ' increment by ' || to_char(p_new_value-p_current_value);
18 execute immediate 'select ' || p_sequence_name || '.nextval from dual' into l_dummy;
19 execute immediate 'alter sequence ' || p_sequence_name || ' increment by 1';
20 end reset_sequence_value
21 ;
22 begin
23 execute immediate
24 'select ' || p_sequence_name || '.nextval,' || p_sequence_name || '_user.nextval from dual'
25 into l_nextval1, l_nextval2
26 ;
27 if l_nextval1 < l_nextval2
28 then
29 reset_sequence_value(p_sequence_name,l_nextval1,l_nextval2);
30 end if
31 ;
32 if l_nextval1 > l_nextval2
33 then
34 reset_sequence_value(p_sequence_name || '_user',l_nextval2,l_nextval1);
35 end if
36 ;
37 p_nextval := greatest(l_nextval1,l_nextval2)
38 ;
39 end reset_sequences;

My messages won't say the contact name only shows the phone number, how do you change this when the contact is in my phone under that number already?
I thought that at first, but I have text this person before and had received responses in a timely manner. Its just weird that it all of a sudden removed their name.
Would this affect the delivery of the text message? -
Variable/method names standardizing
Hi All,
The problem we've got here is that same things are named in slightly different way by different developers or development groups.
Typical example:
'id' property. accessors could be named like: 'getID' or 'getId'.
Or even better example: term 'Work List' implementation of which has nothing to do with Java List. So, property could be named as 'worklist' or 'workList' with similar names for accessors.
I think, this problem is slightly outside of coding standards scope. And as project is very massive ~300000 lines of code, there are a lot of different terms named like in example above.
Has anyone come across such problem before?
I suspect, solution would be to keep a kind of variable/method names library.
Are there any better solutions?
Thanks in advance
AndreiI think, this problem is slightly outside of coding
standards scope. It is, and I'm glad it is because the "people" who make the standards that we do have end up creating dumb, inconsistent stuff as it is. Better they don't get too granular.
Has anyone come across such problem before?Every day
I suspect, solution would be to keep a kind of
variable/method names library.
Are there any better solutions?How you name stuff is a matter of opinion. I personally don't care if you do someID or someId or even someid, what kills me is stuff like someid and someid. But again, it's all what you're used to. -

Err this is no longer April 1st you know.
The iPod Shuffle has never had a 'display' on which track names can be shown. See http://www.apple.com/ipod-shuffle/ if you want an iPod which does have a display on which you can see the tracks names and even the album cover art then look instead at the bigger and more expensive iPod Nano http://www.apple.com/ipod-nano/ or iPod Touch http://www.apple.com/ipod-touch/
PS. The current iPod Shuffle even though it has no display on which it can show the track names can read them out loud to you using a voice-synthesiser this is the VoiceOver feature described on the iPod Shuffle product page I listed above. -
How do I stop my iWeb site folder name from showing in the URL?
I have looked through the forum but cannot find exactly what I need.
I am sure there is a way to stop this from happening but I do not want my iWeb site name to show in the URL. Anyone else had this problem that can spread some light on the situation?
Here is how it is showing:
www.ilovehopetown.com/ILove_Hope_Town/The_Ultimate_Guide_To_HopeTown.html
I want to to just be www.ilovehopetown.com and then the page name.
Any help will be appreciated.
RobWhat happens if I leave Site name blank?
Try it and see.
If you are using iWeb 09, the right forum to ask things in is here:
http://discussions.apple.com/forum.jspa?forumID=1309
Two options you could try are naming your site the same as the default folder used by your sever (e.g. public_http or whatever) or forwarding www.myname.com to www.myname.com/sitename -
Hi There
My apple account was in my partners name , I have now changed it to my name .
The problem is my icloud email still shows up his name at the beginning of my email address. eg Jo Blogg ( [email protected] ) .
When I open up Icloud in browser it shows in the top right my correct name , but when I go into Account settings on Mac in the Mail it shows up my
partners name as the Full Name associated with the account . It doesn't give you the option of changing that name though.
I hope I have explained this properly and someone can help ?
Cheers
LizzeeeHey There I didn't need to change it as it shows my correct name in my icloud account. The problem is on my Mac where it still shows my Full name as my partners name.
For eg. if I send an email from "Mail" on mac and I use my icloud account then the name that shows up is my partners name when the email is received. If I send an email from the Icloud Mail box that I log into on my browser then the name that shows up when the email is received is my name which is correct.
When I go into preferences in "Mail" on my Mac to change my name, the name is ghosted out and doesn't allow me to change it ! ? It is here that it still show my partners name ? -

Changed Airport Express names, not showing correctly in iTunes
I needed to swap the location of two Airport Express units, and I renamed them accordingly. They show up properly within Airport Utility/OS X, but within iTunes they seem to be cached to their old names. How do I reset them, flush the cache, or simply get them to show properly within iTunes?
another forum answered it.
airport utility, manual setup, music tab, there is a space for the name to show in itunes.
simple and solved. -
Hello, I would like to create and print a contact sheet in Photoshop elements 13. I have managed to do that but I need desperately to be able to place a title on the contact sheet. Also, each photograph has as name and I need these names to show up on the contact sheet when I print them out. If this is not possible I will just return my product. I have an old old version of Photoshop that will do just that but with this new elements I cannot find it.

What computer operating system is your Premiere Elements 13/13.1 running on?
Assuming Windows 7, 8, or 8.1 64 bit, open the Elements Organizer 13/13.1 and select your media
for the Contact Sheet.
Go to File Menu/Print and set up the Print Dialog for Contact Sheet.
If you used Edit Menu/Add Caption beforehand, I can see how you can get
Date
Caption
Filename
under the Print dialog's "4" and even a page number if you have more than 1 page. But, I am not seeing
where you are going to get a title for each of the contact sheets.
Any questions or need clarification, please do not hesitate to ask.
You can get into the Elements Organizer 13/13.1 from the Welcome Screen or by clicking on the Organizer Tab
at the bottom of the Expert workspace in the Premiere Elements 13/13.1 Editor.
Please let us know if we have targeted your quesiton..
Thank you.
