Tracking Application in Apex

Hi gurus
Is there any Application for the System Change tracking in Apex
THANKS

Hi
If you head to the OTN site for apex and go through to the packaged applications, there is a bug tracker that could probably be modified for your purposes.
Cheers

P-Track Application Not Sending Mail

I'm running the P-Track application on APEX 4.2.2 w/ Embeded PL/SQL gateway Oracle 11.2.0.2 DB. Whenever I try to send a report via email from the app it says it was successfully sent, however no email is received. Whenever I check the APEX mail queue I can see the messages with the following error:
ORA-29279: SMTP permanent error: 501 5.1.7 Invalid address
I tried the format "[email protected]" and "apexuser" (valid APEX user) but neither work.
I can successfully send email from within APEX but not the application.
Thanks,
Leighton

In the schemas with ptrack, I created this function to be called by apex (I prefixed it with EBA so that I would easily identify this as being part of apex packaged apps, as they do their code) with the comma delimited string of "people":
create or replace
FUNCTION EBA_VALIDATE_EMAIL
(p_email      IN VARCHAR2
,p_domain IN VARCHAR2 DEFAULT '@yourdomain.org')
RETURN VARCHAR2 IS
lt_emails apex_application_global.vc_arr2;
email_string varchar2(4000);
BEGIN
-- split string into separate addresses
lt_emails := apex_util.string_to_table(p_string    => REPLACE(p_email,' '), p_separator => ',');
   FOR i IN 1..lt_emails.COUNT LOOP
    if (instr (lt_emails(i), '@')=0) then -- no at sign, so lets append the default domain or the passed domain
      lt_emails(i):=lt_emails(i) || p_domain;
    end if;
    email_string:= email_string || ',' || lt_emails(i); -- assemble the new list
END LOOP email_val;
return substr(email_string,2); -- remove leading comma and return the new list
END EBA_VALIDATE_EMAIL;ie, input could be "Joe, [email protected], [email protected], frank, ron" and it'd return *"[email protected], [email protected], [email protected], [email protected], [email protected]"*
In any apex application, but in this case P-Track, I wrap the page variable with the function in the page process where email is sent, from inside the apex_mail_send calls: on Page 20, 37, and 85 - I haven't made any other changes:
*(this is a snippet from P20):*
declare
   l_clob clob;
   l_message varchar2(4000);
   l_to varchar2(64):=:P20_TO;
   l_from varchar2(64):=:P20_FROM;
   l_cc varchar2(64):=:P20_CC;
begin
for c1 in (select clob001 from apex_collections where collection_name = 'EMAIL') loop
l_clob := c1.clob001;
l_message := nvl(:P20_MESSAGE,'');
l_clob := '<html><body>'||l_message||l_clob||'</body></html>';
APEX_MAIL.SEND(
    p_to => eba_validate_email(l_to),
    p_from => eba_validate_email(l_from),
    p_body => nvl(to_clob(l_message),''),
    p_body_html => l_clob,
    p_subj => :P20_SUBJECT,
    p_cc => eba_validate_email(l_cc),
    p_bcc   => null,
    p_replyto => l_from);
apex_mail.push_queue;
end loop;
commit;It's simple and not otherwise very amazing, but it works swimmingly for us. All our users are AD authenticated via ldap, and none of them as owners or otherwise throughout the apps are known as whomever@domain.. only as whomever. It was a must have, but it also fixed the issue for me that I think you are experiencing with the invalid FROM not having a domain.
With that said, I also changed the assignment of the :P20_FROM which is display only on that page -- to be a plsql function body,
return lower (:APP_USER);.. but this could have been forced in the process block of code too, or alternatively I could have not used a call to apex_mail_send there, but made my function send the email and grab the APP_USER there.. etc etc etc (so many ways to arrive at the same result)

How to realise a point track application with user-defined original point?

hi,
I am developing a simple point track application, it is not the same as the traditional mouse cursor tracking problem and i get really confused.
there are two pictures to describe my application：
the first one descirbes the default state of my application：
1.red circle is the point that user can move;
2.white cross is the original point;
3.blue circle is the range of red circle motion
the second one describes the track process of my application：
1.user can move the red circle with a click of mouse button in any place within blue circle;
2.application should show coordinates of red circle relative to white circle in real time;
3.once user release the red circle(or the button of mouse), the application should return to its default state.
I realy do not know how to realise the key parts of this application, like showing a circle in panel and connecting the points within it to the labview code? can anybody give me some suggestions? thanks a lot

Attached is a very rough implementation of what you're looking for. Add a "draw (white) line" after the "draw circle" function to make the crosshairs persist when the circle is near the center. Prob want to delete the crosshairs from the blue circle picture (currently contained in a constant) to avoid drawing them twice and them not quite lining up. All of the constants are empirically determined and need slight adjustments (e.g. centering of the red circle when mouse is up, etc.). They will need further adjustment if you resize the blue circle picture.
Not sure what you mean by connecting the points within the LV code. I suspect you're using the eyeball to drive an XY stage or such and need to use the red circle coordinates to moderate the travel speed?

How to Import 3.0 application in APEX 3.2?

How to Import 3.0 application in APEX 3.2? These two are on two different machines. It is not upgrade.
Pls help.

Hello,
APEX supports backward compatibility. It means that 3.2 version can run any application that was developed in earlier versions.
In your case, just export the full application from 3.0 and import it in the 3.2

Help deleting an application in Apex 3.2.1.00.12 on 10g XE

Hi,
I imported an application (timesheets demo application) by running the install script in an SQLPLUS session which I understand now was not the proper way to do this.
Now I need to delete this application but I'm receiving the following error when trying to delete the application in APEX:
ORA-20000: User ADMIN has no privileges on the EBA schema.
What do I need to do in order to delete this application?
Thank you.
Francois

Hi Francois,
You could try to login in SQLPLUS the way you did when you imported the application and then run the following code.
BEGIN
APEX_INSTANCE_ADMIN.REMOVE_APPLICATION(xxx);
END;Where xxx is the Application ID.

ps: Apex 3.2? Time to upgrade...

Issue in Change tracker application

Hi all,
We have enabled Change tracking in our repository when it was enabled there were only 3 Display fields in our repository and the tracking was done as is in the change tracking application under the column Record shows all the Display fields.
Now because of business requirements we have activated another field in our repository as a Display field, now when i login to change tracking application old records under Record column still shows the 3 Display fields in the Record column of the change tracker application.
I went and changed a record which falls in the Change tracking criteria, now i see 4 Display fields in the Record column of change tracker application as there are 4 display fields currently.
There is an in consistency in the data in the application now for few records there are 3 and 4 fields in the record column. Is this how the system behaves?
I think the logic is like this when ever there is a change happening in the repository, insert query is used to update the A2I_CM_History table with the existing data(at that moment how many fields were enabled as DISPLAY )with out any relationship to the Main table Display fields. Please correct me if i am wrong, it was just an assumption.
If any workarounds to this problem will be of a great help.
regards
Sowseel

Hi Gabor,
Thanks for your reply!
We have checked that note and we have indexes existing for few other fields as well in the table, but still we are facing the same issue.
Thanks & Regards,
Ravi

Migrate/Import/[etc.] PL/SQL Web-Toolkit Application to APEX

Hello all,
I've only recently learned about APEX and have dabbled with it for a little while, and I'm quite impressed with how amazingly quick it is to develop applications with it.
A few co-workers and myself are trying to convince "The Management" that we should pursue using APEX to develop our Enterprise Applications. Currently we write our web apps using the PL/SQL WebToolkit, accessing our applications at URL's like: http://host/dad/[package.]procedure .
Recently (within the past month) there was a convention in the Southern California region where I believe some people from TUSC presented on APEX. As I understand it, they said it was possible to migrate existing applications (written in packages and procedures) to APEX. I'm also told that it is possible to view the PL/SQL that is rendered by APEX to display the application.
We've practically sold our Director, however he has a few outstanding issues he's asked me to research, as he feels his boss would be most concerned with:
* How much effort will it take to migrate/import/etc the PL/SQL WebToolkit Application to APEX
* Should the need arise, how much effort would it take to move from APEX back to PL/SQL WebToolkit
I've tried researching these topics over the past few days and I haven't really come up with much. I realize that you can call PL/SQL packages/procedures/etc from within a region, but as I read on a thread in these forums ( How to jump from mod_plsql to APEX! ), you still won't be able to take advantage of the Items, Computations, Processes, etc. Is there, in fact, a way of importing a PL/SQL-developed Web Application into APEX to take advantage of all its tools? I would imagine it would be quite a feat to be able to create the items for the form fields, maintain the layout and such, but I need to provide my Director with as much information on these topics as possible.
Many of us developers are really excited at the prospect of developing with this tool; it would be a shame to lose the opportunity over not being able to provide any information on the topics above.
Thanks in advance for your assistance,
-Luis

Hi Luis,
I had a client a couple of years back who had an existing PL/SQL Web Toolkit application who used the htp.p etc calls to generate the HTML (and in some cases CSS) for their site. They were interested in using Application Express and asked me to design a new administration module for their site (which I did). The development went extremely smoothly so they then asked about re-writing their existing site in APEX (since maintaining the old site was not a straight-forward task).
Fortunately for me, the original designer had the foresight to put lots of the application logic into packages (which I could reuse), but I quickly (about 2 or 3 days from memory) created a custom theme and templates in APEX which gave the same look and feel as the existing site.
Personally, I think if you tried to re-use the existing htp.p calls (by using PL/SQL regions etc), then you would be missing out on some of the major advantages of using APEX (such as the ability to easily change the look and feel of your application).
I always think that migrating to a new tool/platform etc is a great opportunity to re-examine your existing code to perhaps see if you can do things differently (speed up those queries, perhaps make the navigation more logical etc).
So, yes you can certainly re-use lots of your existing packaged logic, but I would also take the leap and use the features that Application Express provides to make future maintenance of your application easier.
Just my thoughts.
John.

Issue Tracking Application

Can someone please help.
I have been through Chapter 10 of the 2 Day Play Application Express Developer Guide 2.1, "How to Build and Deploy an Issue Tracking Application".
At run time when I select the Delete button, the confirmation box appears. Selecting Yes gives this error:
Contact your application administrator.
Error ERR-1016 Application "108" Page "0" not found (requested language="en-us")
OK
Can I change this to return to the original Issues page 6?
Thanks
Pat.

Pat,
Yes, you should be able to change this. Look for the branch that is associated with the Delete button.

I lost my ipod with no tracking application

I lost my ipod today and I wish I could locate but I have no tracking applications above is there a way to recover anyway (excuse my mistakes I'm French and I used google translation because I could not find the French forum).

- You do not need any app. If you previously turned on FIndMyiPod and wifi is on and connect go to iCloud: Find My iPhone, sign in and and go to FIndMyiPhone. If the iPod has been restored it will never show up.
- You can also wipe/erase the iPod and hae to iPod play a sound via iCloud.
- Change the passwords for all accounts used on the iPod and report to police
- Apple will do nothing

Export Application from apex 4.0 to 4.1

Hi guys,
I exported an application created on apex 4.0 And oracle 11g express beta. Then imported the application into APEX 4.1 ( in the could ).
The problem is whenever I click on the "Edit Links" I get kicked out from the work space and I have to log in again.
** "Edit Links" are working in other applications ...
I hope my question is clear ..
Do you have any Hint ???

NOT really possible to go backwards from 4.x to 3.s. Your best option is to try and find a backup and try and install it and make required changes to meet current version. Why, may I ask is your production environment in 4.x and your development in 3.2? This sounds TOTALLY dainbramaged to me, since I would NOT want to work in such a mixed environment.
Thank you,

Exporting application from apex 4.0.1.00.03 to 3.2.1.00.12

Hello All,
Recently we upgraded our Live application to apex V4.0.1.00.03. This was running previously in V3.2.1.00.12, my development still uses the old version(3.2) and no ideas of upgrading it as of now.
Accidentally my latest development copy is missing, I have an only option to export back from live to V3.2 to produce latest changes in my development. I know it would be a question of doing, but is there any possibilities.
Any help on this would be really grateful.

Creating a simple image application in Apex

select
"IMAGE_ID",
<img src="#OWNER#.deliver_thumbnail?p_image_id='||IMAGE_ID||'"/> thumbnail,
"FILENAME" from "ORDIMAGE_IMAGES"
where
instr(upper("FILENAME"),upper(nvl(:P1_REPORT_SEARCH,"FILENAME"))) >
Its is showing an error
showing only the coding part when i run the application instead of showing image....
can you please help me rectify the error
Edited by: 880021 on 17-Aug-2011 20:58

Creating a simple image application in Apex
Create a new application from scratch. Name it ORDImages_images.
Add a Report and Form Page based on your ORDImage_images table. Ensure that you select a Classic Report (i.e. not Interactive, which is the default). As expected, two pages are created.
Continue to create the application and then run it.
After the login page, there will be spurious entries for image and thumbnail.
This is expected because of the ORDImage columns in the images table.
Edit Page 1 and open the Images Region
The Source entry is
select
"IMAGE_ID",
"IMAGE",
"THUMBNAIL",
"FILENAME"
from "ORDIMAGE_IMAGES"
where
instr(upper("FILENAME"),upper(nvl(:P1_REPORT_SEARCH,"FILENAME"))) > 0
In SQL Developer, create the deliver_images_thumb procedure
CREATE OR REPLACE PROCEDURE deliver_thumbnail(p_image_id IN NUMBER) IS
l_thumbnail ORDSYS.ORDImage;
BEGIN
-- Fetch the thumbnail from the database
SELECT thumbnail
INTO l_thumbnail
FROM ORDImage_images
WHERE image_id = p_image_id;
-- Check update time if browser sent If-Modified-Since header
IF ordplsgwyutil.cache_is_valid( l_thumbnail.getUpdateTime() )THEN
owa_util.status_line( ordplsgwyutil.http_status_not_modified );
RETURN;
END IF;
-- Set the MIME type and deliver the image to the browser.
owa_util.mime_header( l_thumbnail.mimeType, FALSE );
ordplsgwyutil.set_last_modified( l_thumbnail.getUpdateTime() );
owa_util.http_header_close();
IF owa_util.get_cgi_env( 'REQUEST_METHOD' ) <> 'HEAD' THEN
wpg_docload.download_file( l_thumbnail.source.localData );
END IF;
END;
Then
GRANT EXECUTE ON deliver_thumbnail TO PUBLIC;
Return to Apex and change the Source entry to
select
"IMAGE_ID",
'<img src="#OWNER#.deliver_thumbnail?p_image_id='||IMAGE_ID||'"/>' thumbnail,
"FILENAME" from "ORDIMAGE_IMAGES"
where
instr(upper("FILENAME"),upper(nvl(:P1_REPORT_SEARCH,"FILENAME"))) > 0
Apply changes and run the application
You can now search on substrings of filenames. Note that the image_ID is not shown. To rectify this, Edit Page 1 and open Report in Regions.
Edit the image_id and under Column Link, change the Link Text to #IMAGE_ID#. Also change the Heading in the Column Attributes to Image ID.
Apply the changes and re-run.
Clicking on the image_id link takes you to Page 2 – the form for that image.
Page 2 is sparse so reveal the image_id by Editing Page 2 and opening the P2_IMAGE_ID Page Item. Change Display as Hidden to Text Field. Apply changes and re-run.
In Page Items, open and delete the P2_THUMBNAIL item.
Open the P2_IMAGE item.
Under Name, change the Display As entry to Display Image (from the select list).
Under Settings, change the Based On entry to BLOB Column returned by SQL Statement
Enter
SELECT i.image.source.localdata
FROM ORDimage_images i
WHERE image_id = :P2_IMAGE_ID
as the SQL Statement
Apply changes and re-run the application
Making an image clickable
Edit Page 1 and open Report in Regions. Edit THUMBNAIL and under Column Link, insert
<img src="#OWNER#.deliver_thumbnail?p_image_id=#IMAGE_ID#"/>
as Link Text.
Select Page 2 as the Target Page in this Application.
Finally, set Item 1's name to P2_IMAGE_ID and its Value to #IMAGE_ID#
Removing the Spreadsheet link
Under Report Attributes, set Enable CSV Output to No

How to track application exit event?

I have my swf embeded in Asp.Net. I want to track application exit event. Is there any event which is called when flex application exists or unload or destroyed? I tried application close event but it is not working. I do not want events of browser close or etc because I already tried it.
Thanks,
-Chandu

if you wanted to just close the window all together you could write some Javascript to close the window, then in your flex app call the function when they click the logout button
If you want to actually end it with Actionscript you could try:
public function applicationExit():void {
     var exitingEvent:Event = new Event(Event.EXITING, false, true);
     NativeApplication.nativeApplication.dispatchEvent(exitingEvent);
     if (!exitingEvent.isDefaultPrevented()) {
          NativeApplication.nativeApplication.exit();
