Howto create a ValidateSet with dynamic (runtime) values?

Hi Scripting Guys!
I want to use the auto complete feature in my function for a specific parameter using a "dynamic" validate set (Similar to the Get-Service function and the Name parameter).
For example, instead of this:
function Test-Function
Param
[ValidateSet("Folder1", "Folder2", "Folder3")]
$Param1
I want to get the validate set populated by a function like all Folders from the C drive :
function Test-Function
Param
[ValidateSet(ls c:\ -Directory | select -ExpandProperty Name)]
$Param1
Any suggestions?
Thanks,
Martin

Funny you should ask. Martin Schvartzman has recently posted an example of exactly
how to use dynamic validate set.

Has anyone been able to create a HtmlDataTable with dynamic col and rows?

Has anyone been able to create a HtmlDataTable with dynamic col and rows?
If so please explain. I am successfully able to dynamically add columns using the getChildren method of the htmldatatable object
BUT for each new column created no data is displayed.
I am only able to display data for columns originally created when i clicked and dragged the dataTable icon from the pallette in netbeans visual web kit.
Any help on this is greatly appreciated. I have been searching the web and these forums for around 8 hours and no one seems to have a working example of this. Lots of similar posts asking how to do it though :(
Thanks in advance.

Prompts with dynamic default values

I have a request from my client to modify several reports so that two date prompts will have default values populated with the first and last day of the previous month. All of the reports are currently using custom sql so I have to be able get the dynamic default value in the extended @prompt syntax. However, I am not able to use any of the sql functions since the functions merely appear as plain text as the default value itself.
I have found a few work arounds to achieve the functionality of the dynamic prompts, but I cannot get the actual default value displayed to the user to be dynamic. Is it possible to achieve this by using only the custom sql?

I know how to do the insert to database, but can anyone please let me know how to create a table that allows user to enter data and how to create a add 1 row button?
Thanks in Advance!

Raghu,
Go through the ToolBox tutorial Create Page & Advanced table section of OAF Guide.
Step 1 - You require to create EO & a VO based on this EO. This EO will be of DataBase table where you want to insert the data.
Step 2 - Create a Advanced table region. (Refer this Adavanced table section for more on this)
Step 3 - Attach this VO in the BC4J component of Adavanced Table region.

Howto create SCEP profile with ICPU to enroll with MEM server on Lion

After biting the bullet and ordering more RAM, my computer now is working a ton better. So that must have been the main issue. With 8 GB RAM, I can now even run Parallels fluidly (better than my work PC!) where before simple things like logging in to my MBP after reboot could take forever.
The place I went to had several other people getting RAM upgrades at the same time as me, so between this and other comments I've seen in discussions here and elsewhere on the Internets, I take it to mean that either Apple should bump up the base RAM on its new machines, and/or stop charging so much for additional RAM.
I refused to believe a Pro machine bought with Lion installed would come with too little RAM for light to medium usage, but it was apparently the case. I'll mark this as a correct answer and hope some other poor soul will come across this thread and be helped by it.

Create configuration guide with IMG object values

Hello all!
Is it possible to generate configuration guide not only with the IMG objects but also with IMG object values?
For instance, if we filled in plant 1000 in customizing, then could this value also be present on the generated configuration guide?
Regards
Martin

Sorry, seems I was unclear with the question.
I meant the generated word document that can be generated with SOLAR02->Configuration->Generate configuration document.
Here I can download the objects specified in the configuration tab to a word document with the help of a visual basic macro but the content of the IMG objects does not get downloaded.
When I look at the macro in the generated word document, this functionality seems to be somewhat supported but I cannot make the system generate the appropriate excel files..

How to create a report with dynamic columns

Hi all,
I am using Apex 4.0 with Oracle 10g
I am creating a report and I need to display columns dynamically based on the item values.
example:
I have a table employee with columns name, designation, sal
In the report page i have a select list with designations and when I select a designation from the select list,
I need to display the names of the employees horizontally,
like each name as a new column in the report with that particular designation. and same has to continue when I select different designations.
Can some one help me how we can do that.
I appreciate your answer
Thanks,
Rik

Essentially you want to write a pl/sql function which returns a varchar2 string. The contents of the string must be a valid sql statement.
Once you have done this, you need to add a report region as type sql report and you will have the option of writing it as a query or as a function returning query. Choose function returning query and enter in the function call.
Note your function must be valid, and must be executable by your apex parsing schema.
example:
create or replace
function test_report( p1_tablename in varchar2)
return varchar2
is
v_query varchar2(4000);
begin
v_query :=
'SELECT * from '||p_tablename;
return v_query;
end test_report;Edited by: Keith Jamieson on Aug 15, 2011 4:50 PM

This very simple: We cannot use dynamic SQL from used-defined functions written in T-SQL. This is because you are not permitted do anything in a UDF that could change the database state (as the UDF may be invoked as part of a query). Since you can
do anything from dynamic SQL, including updates, it is obvious why dynamic SQL is not permitted as per the microsoft..
In SQL 2005 and later, we could implement your function as a CLR function. Recall that all data access from the CLR is dynamic SQL. (here you are safe-guarded, so that if you perform an update operation from your function, you will get caught.) A word of warning
though: data access from scalar UDFs can often give performance problems and its not recommended too..

How to create fillable PDF with dynamic content dropdowns?

I'm creating a March Madness bracket for people that don't really understand how they work. What I'd like to do is have dropdowns for each of bracket lines (they would list the teams playing against each other for that game and they would select who they think would win). I would then like the dropdown for the next game to auto-populate with only the two options for the next round.
For example, team A and team B play against each other and teams C and D play against each other. There are two separate dropdowns, one with A and B as choices and the other with C and D as choices. The user thinks A and C will win their games, so the next dropdown would only have the options of selecting A and C. To illustrate:
AA and B are listed in the dropdown, and the user selects A to win.
BA or C are listed in the dropdown because the user has selected A and C to win their previous games.
CC and D are listed in the dropdown, and the user selects C to win.
D
I can make the first round dropdowns just fine, but I'm not sure how to conditionally/dynamically populate the second round dropdowns based off of user selections.

I don't understand your request but my english is not the best.
But here you can see a script. You can copy this in the first dropdown in the exit-event.
In this example you will give the first dropdwon the entries
"123"
"345"
"678"
The first case describes what happens when the user clicks "123" the second drowdown will get the entries "456" and "789".
When the user clicks "456" the second drowdown will get the entries "123" and "789".
I think you can adapt this script as you need.
Hope I could help a little bit,
Mandy
switch (xfa.event.newText)
    case "123":
        DropdownListe2.clearItems();
        DropdownListe2.addItem("Please select a value");
        DropdownListe2.addItem("456");
        DropdownListe2.addItem("789");
        DropdownListe2.selectedIndex = 0;
        break;
    case "456":
        DropdownListe2.clearItems();
        DropdownListe2.addItem("Please select a value");
        DropdownListe2.addItem("123");
        DropdownListe2.addItem("789");

        break;

How to create a PDF with substituted key-value and table-values using a template language

I have about 50 key-values and 10 table-values that I want to substitute into a formatted report template (language can be anything standard, would create a small number of these templates) and then use an Adobe tool to substitute the values into the template and produce a PDF. Preferably the template language would permit some basic conditional logic (if <key #> has value <value> then <show key label here> and <key value here> in close spatial proximity on the form) and permit embedding of a static graphic logo, text with fonts/styles, etc. to produce a polished report but also handle pagination (e.g. enable page breaks or numbering) to be handled automatically.
What is a recommended template language and product to accomplish this?

Are you thinking of something like a blank form that you can enter information into, save, and send to another user? If so, what you want is possible. If you want more information, post again and include more details about how you want to use it and how the recipient will use it.

How would I create a PDF with dynamic spelling notations intact?

Hi Everyone,
Is there a way to print a PDF version of everything I see on the screen when I run the Dynamic Spellcheck in InDesign? I'd like to send everyone on my staff a PDF proof that includes all of the spelling suggestions.
I would be extremely grateful for your help. Nothing I've tried seems to work, and this forum is my last hope. Thank you!
Brian

Check this site: http://www.kerntiff.co.uk/products-4-indesign/spellproof-id
Using it, and it works great. There is an option for highlighting words which can be turned off, if you just want the dynamic "squiggles".
It works with printing, but if you want a PDF you have to create the PDF as a postscript and then distill it.
