How to access the form items dynamically

The issue here is that I want to acces the value in the textboxes dynamically
Here is the code ( I know its wrong )
<cfset temp = TaskEntryIDs.Split(',') />
    <cfloop index="x" from="1" to="#arrayLen(temp)#">
    <cfset TempControl = "Form.t"&temp[x]>
    <cfif isdefined("Form.t"&temp[x])>
         <cfoutput>#"Form.t"&temp[x]#</cfoutput><br/>
    </cfif>
    </cfloop>
I don't know the correct way to access it, I know that the textbox name start with T and the task number
I know that the textbox for the task number 74 is t74, but how can I access the value of this text box so I can insert it into to the database ?
Please help me
Thanks

Array Notation:
Form["t" & temp[x]]
StuctKeyExists() is an easier function to determine dynamic form fields exist.
<cfif structKeyExists(form,"t" & temp[x])> rather then isDefined().

How to access the form while processing?

Hello ,
how can one access his form while its processing a certain task - like a query or running a report - in order to cancel or abort this process?..
Thanks...

For being able to interrupt a query you can set the property "Interaction Mode" at form-level.
For any other interruption you have to program it one your own.

AIF Input Parameters - How to access the form interface?

Hi Experts,
i am trying to integrate Adobe Interactive Forms in SAP Records Management, which is working quite good so far. We implemented a Service Provider which uses an Interactive Form as a document template and uses the KPro document attributes as input.
Now my problem: To implement a more generic approach, i need to automatically read the input parameters for the generated funtion module of the form. I debugged quite a lot, but i cannot find any solution. Is there a dictionary table with the name of the form and its input parameters? Or is there a method/funtion module to find out the input parameters for a specific form?
Thanks for ur support,
Jan

Hi Jan,
Perhaps function module FP_FIELD_LIST provides already the information you are looking for. It lists the fields which are required for the form context.
Otherwise you may need to use classes like CL_FP_INTERFACE(IF_FP_INTERFACE~GET_INTERFACE_DATA), which returns IF_FP_INTERFACE_DATA. Here, you could call GET_PARAMETERS, then GET_IMPORT_PARAMETERS. The structure of each parameter is of type SFPIOPAR.
How to get the interface reference? You could use CL_FP_WB_HELPER=>INTERFACE_LOAD_FOR_RUNTIME.
CL_FP_WB_HELPER=>FORM_WHICH_INTERFACE_USED returns the name of the interface for a given form.
Hope that helps.
Best regards,
Andreas

Hello Nigel.
Are you sure the Bookmarks you important are nowhere to be found? They should be stored in your bookmark manager, somewhere. To access the bookmark manager, go into ''Bookmarks > Organize Bookmarks...''. Try searching there.
You can change their place from there too.

In VB Programming code -- How to access the formula for suppressing a field

In VB Programming code -- How to access the formula for suppressing a field
I am using Crystal Reports 2008 v1
Using VB code, I am attempting to modify a Crystal Report before exporting it into a PDF format and then displaying it on the Web.
My problem is that I am unable to access the formula used to dynamically suppress a field.
The following code is working:
mySections = rd.ReportDefinition.Sections
For Each mySection As CrystalDecisions.CrystalReports.Engine.Section In mySections
   ' myFieldToChange is a String set to the text of the field I need to adjust the Suppression
   iloop = 0
   For Each RecObj As CrystalDecisions.CrystalReports.Engine.ReportObject In mySection.ReportObjects
           If mySection.ReportObjects.Item(iloop).Name.ToLower = myFieldToChange Then
               myTextObject = CType(mySection.ReportObjects.Item(iloop), CrystalDecisions.CrystalReports.Engine.TextObject)
               myTextObject.Text = "new field text goes here"
               mySection.SectionFormat.EnableSuppress = True
               ' Here is where I want to change the formula for the Suppression
            End if
            iloop = iloop + 1
    Next
Next
I can not find any reference to the actual suppression formula in the SDK help file.
Note, the EnableSuppress can be set to True for False, but if there is a formula for dynamic suppression, the True or False value is overwritten. The results of the formula determine the suppression.
Is there a way to reference this formula. I know that I can put on in using the Crystal Report Designer software, I need to modify this formula using VB code and the SDK.

Hello, Mark;
If you are using the ReportDocument object you do not have access to the Conditional Suppression formula. You can get around it by using a formula field in the report for the supression and then using the FormulaField code to change it at runtime.
If you want to change the supression condition directly at runtime you need to use RAS and the ReportClientDocument.

Accessing the FORM tag with Javascript.

I ran into the following problem when writing the customization portion of a Java portlet.
I have some JavaScript that I would like to have run when the customization form is submitted (ie, when the user clicks OK or APPLY).
Normally, this is easy to do by specifying the 'onSubmit' event on the <FORM> tag. But I don't seem to have access to the FORM tag
since it's being generated on the fly by Oracle Portal.
So, how do I set up my code/portlet so that I can have some Javascript executed due to the onSubmit event?

I may not be understanding the problem correctly so you may have already tried this:
You should be able to dynamically adjust any form tag's attributes after the form's been generated, you just need to know how it's identified. If Portal isn't assigning it a consistant name you can use, you still might be able to adjust it. If you can place a piece of code "inside" the form, you could access the form tag with: "this.form.onSubmit = ..." That might be your best bet, but the "this" scope can be weird if I remember right. If you don't know that your code will always be inside the form tags, your other choice would be to write a function that will iterate over each form in the frameset and test for a input field name/value that you know is unique to your form. Then you'll be able to identify the form, and finally set the onSubmit value to whatever you want.
Here's some pseudo javascript (I'm too lazy to go grab my reference guide to refresh my memory about the actual syntax you'd use) that might get you started:
foreach form in parent.forms {
if (form.foobar.value == "myUniqueValue") {
var gotmyform = form;
I think. :) It's been a while since I've done such a thing, but that's what I remember.
I don't know squat about Portal (that's why I'm here poking at these forums), so I could be completely off base. If so, I'm sorry.
Good luck,
Sean

How to run the form that is only installed on a PC and not using a server?

Hi
I am new to Oracle and have taken the forms class. But I do not understand how to run the form from my PC using XP windows. (Do not have access to a server).
I have started the OC4J, made sure the listener was started, compiled the form and then when I run it, it automatically goes to the HTTP:
ERROR: res://ieframe.dll/acr_depnx_error.htm#,http://kevin:8889/forms/frmservle
I connected to the database correctly. I can process a report and it does nor try to access the internet. My only issue is running the form. I verified it compiled.
Sorry for a basic question. Could someone please help, I tried reviewing other questions, but not sure if they are connecting to a server or not.
I see webutil but is it required if I don't have a server? Thank you in advance.

Regardless of the version, it appears that you may not have configured the Builder. Do the following:
1. Open the Builder
2. From the menu, select Edit > Preferences > Runtime
3. In the box labeled "Application Server URL:", enter a local URL needed to run a form OR click the button labeled "Reset to Default". If you decide to manually enter a value, it would looks something like this:
http://localhost:8889/forms/frmservlet
4. In the field labeled "Web Browser Location:", enter the path and executable to your preferred browser. So for example if IE is your browser of choice the entry would most likely look like this:
C:\Program Files\Internet Explorer\IEXPLORE.EXE
5. Click on OK and retest.
By the way, you can manually enter a URL in the browser. Clicking the RunForm button from the Builder is strictly optional. To run the "test" form directly from the browser enter the following into the browser's address field:
http://localhost:8889/forms/frmservlet?form=test

How to get the extension Info from firefox? Do we have any firefox API to communicate with the browser? I couldnt see the HTML of the widget displayed in the toolbar how to access the widget using JS or any way

Hi,
Thanks for the suggestion. I've been playing around with some of the classes of the java.net package and java.io
Using the URL class i can get the content of the data from a STATIC page and output that response to file so that is does not display to the client broswer.
But this only works if the URL i give points to a static html page.
So the problem i'm getting is if i'm righting in arguments in the URL, this means that server needs to process the arguments i give and its sends back a dynamic result. Because its dynamic the URL class can not handle this and throws me an exception everytime :(
Have u ever tried to do some things like this?

How to check the selected items of a selectManyListbox in doDML of an EO ?

Hello,
I have a VO based on en EO. During the doDML(UPDATE) of that EO, I would like to check what items of a af:selectManyListbox have been selected.
How could I get the checked items in the selectManyListbox (which belongs to the ViewController) in the doDML method of an EO (which belongs to the Model)?
Many thanks

Hello John,
I know I cannot access the component directly. This is why I asked my question.
The real case is rather complex and long to be copied and pasted here.
Let me simplify it without being too generic.
The VO is based on a hierarchical SQL query. All its EO attributes are transient. This VO is shown as a Tree in the page.
Each node of the Tree has a checkBox. During commit (doDML() of the EO to be precise), for each checked node I need to access the selected items of a selectManyListbox in some proper way to perform further operations on the DB (no matter what now). The selectManyListbox is based on a second VO. As you may understand, the problem is that from the EO I don't have a direct access to the selectManyListbox. Also, as far as I know, the VO the selectManuListBox is based on does not have any informations about the selected elements, since the checkBox in the list cannot be associated to the VO. Basically I cannot know what elements have been choosen.
I hope the problem is clear.

How to access the Text Frame, when we use scrollable frame,

Hi Friends,
How to access the Text Frame, when we use scrollable frame,
Thank you,
[ Nav ]

That's the same question:
how can I access something (a page item) on a page…
Answer: you need something unique in that object you can get a handle on.
Or you use the selection a user of your script is doing and work with that selection…
A "scrollable frame" is nothing special. What it makes it a "scrollable frame" is the DPS software.
So you have to look for attached labels on the object, that identify the object for the PDS plug-in "Overlay Creator" as a "scrollable frame". That's possible with the "extractLabel("KeyString")" function. But you need to know the appropriate key-string in advance.
In another of your thread in the DPS forum, I basically answered the question how to obtain those key-strings.
When knowing the key-string you could loop through all your page items (you can skip all text frames) in the allPageItems-collection, to identify the "scrollable frame" by extracting the right label.
If you have more than one "scollable frames" you need a second unique identifier for the particular object.
That could be nearly any property.
Keep in mind, there is no "scrollableFrames" collection in the DOM !
