Question for Carl Backstrom
Carl:
Regarding
http://htmldb.oracle.com/pls/otn/f?p=11933:1
Can you share some implementation details on how you did this? What is the query for the query region? Where do all the Javascript snippets go?
Thanks
Hello,
>
I was hoping to use this technique to show a one-many
relationship i.e. show the order header on the page
and click on "show_detail" to show the order line
items.
How can that be done?Yes the easiest way would be to just create an iframe in the detail row to access whatever content you want and use the show_detail column to set the URL, this would be the best way if you are opening another HTML DB page with a form that you might want to edit/update.
Or you can go the AJAX route and pull the content from a procedure or package and insert into the detail. This would work best if you are just displaying some data or you need some very particular formatting. It would also be a bit faster than an iframe.
Given some time this week I'll see if I can add those examples.
Also, I didn't quite understand your "disclaimer"
about clicking on that checkbox, everything works
fine without touching that checkbox. Can you clarify
please?If you uncheck the checkbox before you start clicking the show_detail only one detail will be shown at a time. The javascript code will automatically hide the last opened detail row and reset the label. I just didn't write any code to reset the variables between the two different functionality because I figure that most people will have it work just one way or the other.
Thanks,
Carl

Question for Carl Backstrom or others : Tree list
Hello Marvel team,
I am looking to build my application menu like the following example :
http://htmldb.oracle.com/pls/otn/f?p=11933:31
- The menu must appear in each page.
- Some options or sub-options can be disabled depending on oracle users privileges or roles.
- The label menu options will be stored in a table, perhaps with other things ? need ideas?
Need from where can I start building this menu ?
Thanks.
Jina.Hello,
That example is a HTML DB list using one of the builtin DHTML Tree Templates in 2.0 so each element can have conditions associated with it. The drawbacks are that it is static.
There is also this example which used AJAX to pull the branchs http://htmldb.oracle.com/pls/otn/f?p=11933:49 the problem with this example is it doesn't have any conditions for elements though I'm sure it can be done, It also doesn't have any memory between refreshes, (though I know someone who has taken care of that but I'll let the jump in here if they want)
You might want to look at the builtin Tree Item it is a little less dynamic but should be able to do most the of the things you want.

Question for Carl about Show/Hide Detail Rows
Carl,
In your example http://htmldb.oracle.com/pls/otn/f?p=11933:1:2549476012987299
is there a way to modify the javascript code to include multiple variables being passed in, vs just the pID being passed in?
How can I pass the additional variables below:
function ShowHideDetailRow(pThis, pTable, pTR, pID,pID2, pID3){
var l_Detail = 'detail' + pID; //how can I append pID2 and pID3 here?
var l_NumCells = pTR.cells.length;
if (pTR.rowIndex == pTable.rows.length - 1 ||
pTable.rows[pTR.rowIndex+1].className != "detail")
gURL = 'f?p=&APP_ID.:12:'+html_GetElement('pInstance').value+'::NO:RP:P12_SID:'+ pID;//how can I append pID2 and pID3 here?Hello,
Sure just add the parameters in like you have shown javascript is very lenient when it comes to adding parameters.
And as for the URL all you have to do is follow the APEX URL syntax.

Question For Vikas: Select List Colors
Vikas,
I've seen somewhere
you posted a site:
http://htmldb.oracle.com/pls/otn/f?p=24317:104
Can you still do that with an htmldb_item.select_list?
If yes how can you do that because I've been struggling
for weeks to find this answer and all of a sudden now
I've seen your example
Thank youMy example is a variant of the master's example (Carl Backstrom) of a similar nature.
Basically, the styling is done with a Javascript in the region footer, so you can apply it to anything. The code is
var pThis = document.getElementById('P104_SELECT');
var pThose = pThis.getElementsByTagName('OPTION');
for(var j=0;j < pThose.length;j++){
pThose[j].style.background = pThose[j].value;
}Basically, the select list option value itself is the color name.
Things get a little trickier in a tabular form because you have many select lists, but I think the basic concept should hold good. The above code just grabs a specific select list and loops over its options. You would need to wrap it in another loop to grab all the select lists in your tabular form and do the same thing.
Hope this helps. -
[b]Carl Backstrom - A great loss[/b]
I woke up to the news that Carl Backstrom was killed in a car accident (I'm not going to paste the link to the news article as it contains some distressing details that some people may not want to read).
At first I could not believe the news, however it has been 'confirmed' on various blogs and Twitter.
Carl obviously had a huge impact on the APEX tool and the community, however more than that he was a great guy. I've had the pleasure of meeting Carl many times and I consider him a friend.
A very very sad day, my thoughts and condolences are with his family at this difficult time.
John.

REWARDS: Please remember to mark helpful or correct posts on the forum, not just for my answers but for everyone!Hello,
When I first read John’s thread subject, I thought to myself “it’s impossible that Carl decided to leave the APEX team”. Never in my mind I would have thought about such a tragedy.
Carl was a true believer in APEX, and his commitment to it, and to the APEX community, was truly remarkable. When Denes was awarded “APEX developer of the year” I wrote that I believe that a good developer is also measured by his will to share his knowledge with others. Carl is a great example, also in this field. He always shared his vast knowledge with others, always willing to help.
My deepest condolences to Carl’s family and friends.

How can you change your security question for I tunes?
How can you change your security question for I tunes?
If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then the steps half-way down this page give you a reset link on your account : http://support.apple.com/kb/HT5312
If you don't have a rescue email address (you won't be able to add one until you can answer 2 of your questions) then you will need to contact iTunes Support / Apple to get the questions reset.
Contacting Apple about account security : http://support.apple.com/kb/HT5699
When they've been reset (and if you don't already have a rescue email address) you can then use the steps half-way down the HT5312 link above to add a rescue email address for potential future use -
I have an apple id and it has my current email attached to it. however when i go to update apps it's asking for the password for an old email. I no longer have the old email and can't use it. when I go to icloud on my ipad it asks for the password for old email. it doesn't allow me to change the old email to current. when i go to reset it i can't remember the password or security questions for the old email so it doesn't let me go any further. How do I fix this? Do i need to call apple support?
I have the same problem - it is maddening. I rely on this iPad for work so this is not just an annoyance! The above solutions of changing the appleid on the device or on the website do not work.
The old email address no longer exists - I haven't used it in a year probably and I no longer have the account. I logged into the appleid website and there is no trace of the old email address so there is nothing that can be deleted or changed there. On the iPad there is no trace of the old email address so nothing can be deleted there either. I have updated the iPad software and the same problem comes right back. Every 2 seconds I am asked to log in using the old non-existent email. The device is currently useless.
The only recent change to anything was the addition of an Apple TV device, which was set up using the correct login and password.
Does anyone have any ideas? The iPad has been backed up to the iCloud so presumably it now won't recognize the current iCloud account? So restoring may notbe an option? -
I have recently bought an IPAD 2 for my girlfriend and have encountered a problem with purchasing apps through my itunes account. It is requesting that I not only enter my pasword (which I know) but answer my old account questions, which I have forgotten the answers to. It had since locked me out of changing my questions for eight hours. Is there any number I can call to prove that I am the real owner of my itunes account so my girlfriend will be able to use her ipad to purchase new apps without having to go through the trouble of using one of my other apple devices? Random information: I believe my questions were set back in 2007 when I purchased my first ipod nano, since then I have used this same itunes account for my own ipod touch and ipad 2 and my girlfriends iphone 1st generation. I have never run into a problem regarding my questions before on any of these devices

Can somebody give some real time questions for alv report
hi guru
can somebody give some real time questions for alv report.
answers also.
regards
subhasis.hi,
The ALV is a set of function modules and classes and their methods which are added to program code. Developers can use the functionality of the ALV in creating new reports, saving time which might otherwise have been spent on report enhancement
The common features of report are column alignment, sorting, filtering, subtotals, totals etc. <b>To implement these, a lot of coding and logic is to be put. To avoid that we can use a concept called ABAP List Viewer (ALV).</b>
Using ALV, we can have three types of reports:
1. Simple Report
2. Block Report
3. Hierarchical Sequential Report
<b>Reward useful points</b>

Please read my question carefully, this is, I think, a question for the experts. It's not the usual name change question.
When I setup my new MacBook Pro, something slipped by me and my computer was named First-Lasts-MacBook-Pro (using my real first and last name).
I changed the computer name in Preferences/Sharing to a new name and Preferences/Accounts to just be Mike. I can right click on my account name, choose advanced, and see that everything looks right.
However, If I do a scan of my network with my iPhone using the free version of IP Scanner, it lists my computer as First-Lasts-MacBook-Pro! And it lists the user as First-Last.
So even though another Mac just sees my new computer name, and my home folder is Mike, somewhere in the system the original setup with my full name is still stored. And it's available on a network scan. So my full name might show up at a coffee shop.
Can I fully change the name without doing a complete re-install of Lion and all my apps?One thought... you said the iPhone displayed your computer's old name? I think that you must have used the iPhone with this computer before you changed the name. So no one else's iPhone should display your full name unless that iPhone had previously connected to your Mac. For example, I did this exact same change, and I use the Keynote Remote app to connect with my MacBook Pro. It would no longer link with my MacBook Pro under the old name, and I found that I had to unlink and then create a new link under the new name. So the answer to your question is, there is nothing you need to do on the Mac, but rather the phone, and no other phone will display your full name.

Please answer a programming question for an admin
I'm not a programmer (although my interest is growing), so I can't answer this question in a discussion regarding how Win32API w/OLE and COM is SO much better than programming for Unix/OS X applications.
The original discussion was in regards to OS X's superior Unix based security, he devolved to this. Having only begun my venture into programming, his questions are a little above my head at this point. I'm also interested (as an amature programmer), how this would be accomplished in OS X/Unix.
Thanks in advance.
Here's his position:
*(1st entry)*
I have unsed Windows and many flavors of Unix and I have written programs in Assembler, Fortran, Pascal, Cobol, RPG, Smalltak, Basic, PowerBuilder, Delphi, C, C++, C#, Java, and Perl, and I have been programming for over 20 years, so I do have extensive knowledge about programming.
So I have one question for you:
If you had to build a business application that has to allow users to, spell and grammer check, and perform financial calculations, and render the HTML, how would you compare the effort to do this in Windows versus that in Linux, AIX, Solaris or any other Unix operating system?
I can make this business application have these features in ONE DAY on Windows, because COM and OLE lets me, use Word to spell and grammer check, Excel to do the financial calculations, and IE to render the HTML!
I make my living building complex customized business software, and Windows allow me to build these applications by myself in weeks, when it would take me and a team of programmers months to do these same things in Unix because of the lack of an the Win32 API, COM, and OLE, or I would have to BUY third party libraries that did these things, and deal with the licensing, versioning, and vendor problems that go with them, and none of those third party librabries would be close to Word, Excel, and IE in CAPABILITY!
HONESTLY tell me and others reading this thread how you would go about create the customized business application I described above by yourself in a Unix instead of Windows, and tell us how many MONTHS or YEARS it would take you, or how you would have to BUY some other third party libraries to do what Word, Excel, and IE!
Anyone who thinks a Unix has more CAPABILITIES than Windows, has never used Win32API/COM/OLE/.Net, and does not build customized complex business software for a living, because we people that do are the reason that you find some much customized business desktop software for Windows, and so little for any Unix.
I have nothing against Unix, and it is great for simple business tasked server software, but for complex business tasked desktop software Windows with Win32API/COM/OLE/.Net wins hands down!
*(2nd Entry)*
A System administrators view of an operating system and an application developers view are entirely different, and the Win32API/COM/OLE/.NET simply make my job so much easier, and you simply don't understand because you do not have to deal with the "dirty' details of making what a user wants, which is why your definition of "integration" and mines are totally different!
With the spell check you talked about, how will you keep in in synch with the dictionary in Word where the user is constantly adding and removing words?
No, you would have the user to have to maintain two different spell check dictionaries, and you would totally ignore the grammer check requirement!
Cutting and pasting data between applications is simple integration, and not the complex type that I am talking about.
Can you make your application display and use the MacGourmet menus appear in its own window, and to access and use the MacGourmet functionality (ie. search for a recipe) in its own window?
Give me one example of a Unix application that can display the menus of another application, yet alone control its features!
Of course you can't, because you need COM and OLE!
I am quite familiar with different flavors of Unix, but those operating systems do not have the rich API and program integration features namely COM and OLE that Windows has, because it violates the Unix idea of security by process isolation!
Yes that idea of process isolation keeps the operating system safe from malicious code in applications and from one application taking the others down, but you lose the power of programs working together, and you simply cannot build the type of customized business applications that I build by myself, without reinventing the wheel over and over and without having a large team with lots of programmers.
For example, my customers and millions of others spend all day working in Word and Excel, and the Windows idea that I can transparently integrate my complex business applications right in Word and Excel menu, and into their templates and macros, is why third party developers like me prefer Windows over Unix, regardless of how much better security in Unix is.
Do not get me wrong, Java improves business application development on Unix, but unfortuantely it is not feasable to rewrite ever legacy application in Java, and Java does not integrate well with other programming languages.
I used to code business application for both IBM MVS and Sun Solaris, and I never want to go back to those "bad" old days again, once I took the time to learn how to PROPERLY code using Win32API/COM/OLE/.NET!At risk of feeding the troll I'll wander in here:
NOTE: Since this is an Apple programming boards and I have limited experience programming on traditional Unix systems (and most of that in college) I will confine my answers to the area I know.
If you had to build a business application that has to allow users to, spell and grammer check, and perform financial calculations, and render the HTML, how would you compare the effort to do this in Windows versus that in Linux, AIX, Solaris or any other Unix operating system?
I can make this business application have these features in ONE DAY on Windows, because COM and OLE lets me, use Word to spell and grammer check, Excel to do the financial calculations, and IE to render the HTML!
Note that this scenario assumes the user has Microsoft office installed. The person argues that they don't have to purchase libraries to program but what they are effectively doing is simply transferring that cost to user. I don't have to purchase libraries but everyone of my users needs to. Good for you, very good for Microsoft but bad for your customer - IMHO. OK, I know "But all Windows business users have Office installed already." When it comes free with the system then I'll retract my objection.
Under OS X and Cocoa many of these functions are intrinsic to the system layer and do not require any applications to be installed. Using Cocoa you can write a simple Word processor that has rulers, full font manipulation (including kerning, spacing and leading), Document Save and Load, Printing, Export to PDF as well as spell-checking in under 10 lines of actual code. Adding a custom file type and icon for full system integration will add another 5 minutes to your programing.
In case you think I'm blowing smoke here is a tutorial from 2002 (yes, this has been possible for over 5 years) outlining the 8 line Word Processor build in Cocoa. http://www.stone.com/TheCocoa_Files/What_s_sofunny.html
And yes, Cocoa also includes Webkit so I can add full HTML rendering by dragging in a WebKit window to my user interface. For an experienced Cocoa programmer this certainly sounds like less than a day of programming - in fact it sounds like a good tutorial for a middle-experienced training day or 2 day class in Cocoa.
I won't include the link to the 1 line web browser you can build in Cocoa using Webkit because it's shorter than the description. Feel free to search for it if you want to.
HONESTLY tell me and others reading this thread how you would go about create the customized business application I described above by yourself in a Unix instead of Windows, and tell us how many MONTHS or YEARS it would take you, or how you would have to BUY some other third party libraries to do what Word, Excel, and IE!
BUT this is all done from the stock system that is on every OS X computer not simply those with Office installed. Obviously you'd need to add some features that were more complicated than this - because any halfway decent programmer could turn this stuff out - and polish takes a while but to meet the requirements of the challenge it would take 2 days tops.
Is every *nix programming environment like this? I don't know I can only answer for the system that I have experience with and is the concern of this board. If you really have questions regarding *nix programming then I suggest you find an appropriate board and troll^H^H^H^H^H ask there.
If you're ever serious about programming on the Mac feel free to stop by and actually take a look at it. I think you'll be surprised.
