Creating Drop Down Lists in J2ME

Hello all,
I'm not an experienced programmer, and I fear that the rumours of posting a crie for help only to be set upon by hundreds of blood thirsty 'newbe' hunters may be true, but here goes none the less.
Would love to know if any kind soul has hints on how to create drop down lists in J2ME, for selecting a option which would be able to relate to a database (Table).
At the moment I'm using straight forward TextField entries, which is hardly convenient! :)
Any help/comments/sweets appreciated!
Cam

Hi Cameron,
Only MIDP 2.0 support drop down list. So if you currently coding in the MIDP 2.0 environment, here are the codings.
String arr = new String[]{"Happy","Sad"};
ChoiceGroup ch = new ChoiceGroup("Select Choice:",ChoiceGroup.POPUP,arr,null);
append(ch);
Hope this codes is helpful to you.

Creating drop-down list for prodname element in metadata causes errors

Frame 11
DITA 1.2
Due to restrictions beyond our control, we must use absurdly long product names. Therefore I want to use drop-down lists to make it easier for the authors to select a <prodname> in the metadata.
What I did:
1. In metaDecl.eddmod.fm, I created a new attribute and named it prod.
 a. I made it the Choice, and Required.
 b. The Choices currently are just Internal and RTVI for testing purposes. I'll put the absurdly long ones in when I have it working.
 c. I have a Prefix rule of: In all contexts Prefix: Product Name: <$attribute[prod]>
2. I imported metaDecl.eddmod.fm to all of these EDDs:
 In the base EDD folder:
basemap.edd.fm
basetopic.edd.fm
map.eddmod.fm
topic.eddmod.fm
 In the technicalContent EDD folder:
concept.edd.fm
ditabase.edd.fm
generalTask.edd.fm
glossentry.edd.fm
glossgroup.edd.fm
reference.edd.fm
task.edd.fm
topic.edd.fm
3. I imported the element definitions into all of the following:
ChapterOutputTpl.fm
basemap.template.fm
basetopic.template.fm
basetopic.template.fm
topic.template.fm
generalTask.template.fm
glossentry.template.fm
glossgroup.template.fm
map.template.fm
ditabase.template.fm
reference.template.fm
concept.template.fm
task.template.fm
4. I imported the elememted definitions from task.template.fm into my test document (yes, it is a task topic).
What happened:
I get the following error message in the console:
XML Parser Messages (Document Instance)
Error at file H:\DITA_Westminster\Procedures - Our DITA\Inserting_Product_Names_Versions_In_Metadata\InsertingProductNamesAndVersionsInMetad ata.dita.82F, line 28, char 49, Message: Attribute 'prod' is not declared for element 'prodname'
Error at line 28, char 71, Message: Not enough elements to match content model '(prodname,vrmlist,((brand|component|featnum|platform|prognum|series))*)'
What I did next:
1. I removed all elements from the general rule of <prodinfo> with the exception of <prodname>. <prodinfo) is the one that had prodname, vrmlist, (brand|component|featnum|platform|prognum|series) in the general rule. I also did a thorough search to ensure that no other element had this same list of element in the general rule. I couldn't find any.
2. I did the import to the EDDs and templates thing again.
3. I got the same error message again. <sigh />
Question:
Why am I still getting those 2 error messages? They are driving me crazy.
Marsha

Alex Gorly and Matt Sullivan solved one of my issues above:
Message: Attribute 'prod' is not declared for element 'prodname'
I'm still stumpled on the other one:
Message: Not enough elements to match content model '(prodname,vrmlist,((brand|component|featnum|platform|prognum|series) )*)'
As stated above, I've even removed everything from the general rule of <prodinfo> except prodname and I'm still getting the same error. I've searched everywhere for this general rule and <prodinfo> is the only place I can find it.
What I really want is: (prodname), (vrmlist)?, (brand | component | featnum | platform | prognum | series)*
so that vrmlist is optional.
No matter what I do, unless I include a vrmlist, I get the above message. Currently, our CMS can't handle vrmlist but I don't want to remove it altogether because we may be replacing our CMS.
Help please!

How to create drop-down list in Portal??

My case: I have three locations A B C(in the database) for example.
I would like to use drop-down list to show list of All, A, B, and C.
After I choose any of them, for example A, it must show all the data of that particular location and if it is All it must show data of all three locations.
By using Simple Parameter, it's just a static one but I prefer the dynamic one that get directly from the database. And I also got a problem of showing all locations by choosing All in my dropdown menu
Any idea??!?
Thank you so much.

You could try a dynamic page: 
 
&LT;html&GT; 
&LT;body&GT; 
 
&LT;form action="http://host.port/pls/portal/etc." method="get"&GT; 
&LT;select name="location"&GT; 
&LT;ORACLE&GT; 
for rec in (select loc_code, loc_name from locations union select '-1' id, 'All' loc_name from dual) 
loop 
htp.p('&LT;option value="' || rec.loc_code || '"&GT;' || rec.loc_name || '&LT;/option&GT;'); 
end loop; 
&LT;ORACLE&GT; 
&LT;/select&GT; 
&LT;/form&GT; 
 
&LT;/body&GT; 
&LT;/html&GT; 
 
The form should then call your page with a &location=loc_code in the url. Using a page parameter and a bound variable you can access that. You may need to use a decode in your sql to deal with the All scenario: 
 
select ..... where loc_code like decode(:location, -1, loc_code, :location) 
 
Hope this helps.

How do I create a drop down list to e-mail a form for signature.

The desired workflow is for
1)      Firefighter 1 to complete the top portion of the Agreement
section, sign in the Firefighter 1 signature field (which locks the top
portion of the Agreement Section), then select Firefighter 2 from the
e-mail drop down list and e-mail the PDF form to Firefighter 2;
2)      Firefighter 2 opens the e-mail and the PDF attachment,
completes the second portion of the Agreement Section, sign in the
Firefighter 2 signature field (which locks the bottom portion of the
Agreement Section), select Lieutenant 1 from the e-mail drop down list
and e-mail the PDF form to Lieutenant 1;
3)      Lieutenant 1 opens the e-mail and the PDF attachment, checks
the approved box, signs the Lieutenant 1 signature field, select
Lieutenant 2 from the e-mail drop down list and e-mail the PDF form to
Lieutenant 2;
4)      Step three continues through Lieutenant 2, Battalion Chief 1
and Battalion Chief 2
5)      Battalion Chief 2 sends the fully completed form back to
Firefighter 1 who copies the completed form to Firefighter 2
Note: if any of the officers disapprove the agreement the disapproved
form is immediately sent back to Firefighter 1

Hi Katie,
Welcome to Apple Discussions and the Numbers '09 forum.
Numbers vocabulary for this feature is a "Pop-up Menu". It's available as a Cell Format, and is set and edited in the Cell Format Inspector.
See "Using a Checkbox, Slider, Stepper, or Pop-Up Menu in Table Cells" starting on page 96 of the Numbers '09 User Guide.

Create a drop down list in a cell within a table ?

Is there a way to create a drop down list in a cell within a table ? Like the way it can be done in ms word or excell ? I dont mean an interactive pdf/form. I want to create a table in indesign which has drop down lists other people can use to populate a table quickly.

Not possible. InDesign isn't designed to be form-filling software. At best, it can create fields which can be passed on to a PDF file, which usually further has to be edited in Acrobat Pro.
