Displays the value of double type
Hi - another crazy me today. With the help of v % of the SDK. Memorization of the GPS coordinates in a persistent storage which is fine. So want to show these results on a screen by updating a labelField with the value.
the code below, printLn myTest displays a value of something as 42.1234 gets so thin value. However, with the code so I get Double.toString (myTest) cann't find symbol even though I java.lang. *; imported. If I remove this line of double.toString then it will compile, but throws an exception error when I try to display on the screen. Can someone help a newbie pls...
If (persistentHashtable.containsKey ("LVFLat")) {}
Double myTest is (Double) persistentHashtable.get ("LVFLat");.
System.out.println ("# latitude =" + myTest);
String finalLat = Double.toString (myTest);
displayLVFLat.setText (myTest);
}
You must read the documentation of the API and note the use of capital letters and tiny. Capitals: the object, tiny, primitive. Read the API done again and see what I mean.
You want to replace this:
String finalLat = Double.toString (myTest);
with
String finalLat = myTest.toString ();

Hello
You cannot reference variables as you did and get the value of the variable. Use pretty collection.
set serveroutput on size 2000 declare type number_table is table of number; numbers number_table := number_table(10, 20, 30, 40, 50); begin for i in numbers.first .. numbers.last loop dbms_output.put_line(i || '->' || numbers(i)); end loop; end; / anonymous block completed 1->10 2->20 3->30 4->40 5->50

MaheshOAMessageTextInputBean oa = (OAMessageTextInputBean) webBean.findChildRecursive ("ItemNo");
oa.setAttributeValue (SItemNo);There is no such method as setAttributeValue for UI beans, this method is for VO, that is to say if you take a VO and VO a method object to set its attribute.
Bean of the user interface, you will need to use method below,
OAMessageTextInputBean oa = (OAMessageTextInputBean)webBean.findChildRecursive("ItemNo"); oa.setValue(pageContext,SItemNo);

How to display the value of the column
Oracle 10g on Linux
I want to display the value of the id column in the table of www if count (distinct id) is 1. The following query is fine except that it does not display the value of the column ID help, please.
SELECT count(distinct id) FROM www c WHERE C.x_code IN (SELECT D.x_code FROM www_app d WHERE d.y_code = '1151299386') having count(distinct id) = 1
I think you can use MAX in this case
SELECT max(id) FROM www c WHERE C.x_code IN (SELECT D.x_code FROM www_app d WHERE d.y_code = '1151299386') having count(distinct id) = 1

Display the values of the Page element in HTML table
Hi all
could you please help me with the below? I want to have a table in the HTML area and to display in the table of elements of the Page of the page.
I got the code like this:
{
< table >
< tr > < td > & P1_ECEMEA_ASSISTANCE < table > < /tr >
< tr > < td > & P1_ECEMEA_WIP < table > < /tr >
< /table >
}
It shows the element of the Page names in the form of text, not the values.
However, this code without the tags table:
{
ECEMEA request for Assistance of the CQT: & P1_ECEMEA_ASSISTANCE.
ECEMEA CQT Work in Progress: & P1_ECEMEA_WIP.
}
Works and Page element values are displayed.
Is it possible to display the values of the Page element in the HTML table at all or should I use a different method to show the values in a table? The above is only an excerpt of the code. I need to display about 30 items in Page, put in shape in a table with headers.
Please let me know what kind of region is the best to use, or if I have to use only a few symbols of escape in the table code...
Thank you and best regards,
VladimirVladimir,
Looks like you're missing the period after the substitution variables.
{
&P1_ECEMEA_ASSISTANCE. &P1_ECEMEA_WIP. -D.

Need help displaying the value of field in another!
I have a problem, I'm sure is simple but I can't understand it.
I would like to create a field that displays the value of a field point selecteed in drop down. For example, I created a drop down menu which has 3 times that I have assigned values to each:
Items in drop-down list
point: Unlimited time export assigned value: 4 000,00
point: 8-hours coverage export value assigned: 3,000.00
point: 5 hours Covrage export value assigned: 2,000.00
This drop-down list is named "CoverageTime".
I want to create a text called 'Price' field that will display the value of the selected 'CoverageTime' element drop-down list.
For example, if I chose "Unlimited" (which I have highlighted as 4,000.00) in the drop-down list, the 'Price' of text field should display the value of 'CoverageTime' of 4 000,00.
As you can see in my screenshot, I have selected ' Unlimted Time'. The value that I put to this element from the drop-down list is 4,000.00. But the price text field does not the value of the element "Unlimited time", selected in the drop-down list.
How to make this happen? (Sorry for the picture on the side)
I'm not sure what you mean about #1 (there is nowhere where to put the code in the tab Options), but it's okay because the second is on the right track. But to set the value of the field, assign anything you want event.value. So the correct code for the custom script to calculate the price of the text field:
The value of this field for the price of the value selected from the drop-down list
Event.Value = getField("CoverageTime").value;

Display the values of variables
I'm working on a Captivate 5 project in which the values of the variables are assigned and then reassigned. Is it possible to display the value of a variable in a text box or other window to ensure that the value changes? Thank you.
Darin
Hello David,.
It's the way I am especially debugging advanced actions by inserting the variables used in a text of the legend Rick indicates. A long time ago that I wrote two articles on the basic use of variables, perhaps reading could specify:
Use the power of variables without advanced actions
Unleash the power of variables with advanced actions
CAUTION: sometimes the update does not appear immediately. In another thread, I explained how you can refresh the contents of the enhanced TextArea widget that contains a variable that is filled with another widget on the same blade.

Display the value of the element in the HTML area
Is there a way to display the value of an element within an HTML reigion? I know below is not the syntax that is appropriate, but there must be a way to call for the value of an element to display in my HTML code.

Published by: dsn0wman on August 31, 2008 12:58
Published by: dsn0wman on August 31, 2008 12:59You can use the following syntax in the header, html body, or the footor in your area:
& P1_ITEM.
And commercial front and end point are needed.
If you want to format, you can use the following
< span style = "make-weight: bold;" "color: darkblue" > & P1_ITEM. </span >

Displays the value of the variable user based on the advanced run-time action
Captivate 8.0.1.242 - Windows 7 64 bit
I need to display the total duration of the captivate file in a text caption. To do this, after a bit of googling, discovered this total = cpInfoFrameCount/cpInfoFPS. I created a user variable called 'v_totalTime' and in stocks advanced created a standard action called 'totalTime' and added a phrase v_totalTime = cpInfoFrameCount/cpInfoFPS.
Now the weird part is, I don't know how this user variable appears as text. In the text of the legend, when I hit $$ v_totalTime$ $ and overview slides in captivate, the value is not displayed. So I think, the advanced action is not get triggered. So how to get this working?
Even the blog posts that are older than 4 years still not seen at this time.
Every action has to be triggered by an event: events / Actions (Advanced) - Captivate blog
In this case, you can use the event to enter for each slide. This means that the value of v_TotalTime will be refreshed only at the beginning of the slide.
Another tip: type a variable in a text (shape or legend) container ever but still use the X button in the composition of the Panel properties, tab Style role. This will prevent any typos (variables are case-sensitive) and you can also change the default length that will be used to display the variable.
