Display latest value

Hi All,
I have a questions to ask. Is that i create a subvi for my table and it can display latest value at the top. Below attached snapshots of my programming. I uses a random number and stop button to control to let u guys see the whole process of what i want.
but when i change 'true/false constant' and using a numeric control. and i placed it back to my program. It won't lists down the values and it wont display the latest value at the top. what's the problem? I have been stuck at this problem for awhile.
and another question was how to keep the size of the listing be constant? for example, i onli wish to display 30readings on my table. as the programming kept running, the oldest value will be replace. because if kept running my programming, and the listing on my table getting more and more, means memory increases, result in lagging. I don't wish to happen. So is there a way to maintain the fixed table displaying values?
Solved!

Hi Isabella,
I think the problem causes from initializing a shift register in sub vi. If you initialize a shift register, every time sub vi is called, it'll replace value in shift register with initialized value. Uninitialize a shift register should solve a problem. I attached a screenshot of my sub vi for your reference.

Displaying the value of an variable on the stage

I have managed to display the values contained in string variables on stage, and I am happy with that, however when I wish to display the value of an int and convert it to a string as one is supposed to do the output to the stage just calls it [class int] and does not give its value. any suggestions?
My rogram contains a stage at frame 1 which displays a word. The user must input a word. Frame 30 then displays the word which was displayed and the word input by the user. That all works fine. But the value of the variable NumberRight, which has been assigned to that variable will only display as [class int] without showing its value. (even though I have converet it to a string using the .to string function you see below).
My code is as follows;
trace( "The number correct was" + NumberRight); //This works fine in the output window and shows the value of the variable as NumberRight [class int]1 (showing the value to be 1)
outputText.appendText("in/"+textAtIN); //this works fine displaying the word presented and word input by user as in/in
outputText.appendText( NumberRight.toString(     )); //here lies the problem as it just displays [class int] and nothing else.
Yes I have managed to overcome that problem it was some code on the first frame, please excuse, however, now, is there any way to remove the [class int] bit from the displays, I wish to have the results as a clear copy of the results so that they can be printed out, without [class int] all over the place?

Hi Ned thanks for that. Yes I had accidently created blank spaces in the String() argument. (wanted to check if there was a subsequent difference in display and forgot to return them to normal ...Sorted )
Your next suggestion has eliminated the [class int] but I get a value now of 0.
My code on the first frame for a correct response for example is;
function keyPressedIN(event:KeyboardEvent):void
          if (event.keyCode == 13)/*Normally,this will move straight on to the next frame-
          recording a correct response and all that that implies in terms of scores etc. But now I have re directed it to Frame 30 to check are the variables working properly*/
                    //insert code for correct responses vowels etc.
                    VowelI = VowelI+1;
                    NumberRight = NumberRight +1;
                    stage.focus = stage;
                    //There is no need to display the text box as this is a correct response.
                    pupilsResponseIN.visible = false;
                    mainText.visible = false;
                    gotoAndPlay(30);//at the moment this takes me to the display frame to check if all is ok
On the first frame when the user say hits the Return key my code assigns the value of +1 to the variable; eg
NumberRight=NumberRight+1;
and the value of +1 to the value of VowelI
VowelI=VowelI+1
At Frame 30 the code is as follows;
stop();
trace( "The number correct was"+ NumberRight);
outputText.appendText("in/"+textAtIN);
outputText.appendText( "\n");
outputText.appendText("Vowels Correct ="+(int(VowelI).toString()));
outputText.appendText( "\n");
outputText.appendText("TotalCorrect="+(int(NumberRight).toString()));
//outputText.appendText( VowelI.toString());
Now what I am getting is
in/in
Vowels Correct = O
Total Correct = O
Yet the trace (output box) records the Number correct as [class int]1
many years ago I wrote this same program in Authorware using similar code. I am trying to re write it in FlashCS5 using ActionScript 3 and It take days to solve small problems. I notice also that If for example the user of the program makes an error and I record the error as NumberRight =NumberRight -1 the program records it as Total Correct = NaN .
I gave up on this a few months back but I am trying again. I think there must be a better way to do this. Variables do not seem to add up or subtract for me at present. no doubt its me thats got it wrong.

Form displays NULL values

A page is using PL/SQL script to display data. There are 2 display variables. Instead of bringing initial set of data, it displays NULL values. It "fixes" itself after changing variable values from a drop down menu. Why is that and how to fix it?

If you plan on performing all of the work under the Click event, then you won't need to worry about assigning a Script scope to the variables, but if you are planning on using those variables outside of the Event, then David's answer is the way to go.
Another option is to use a hash table as it also works around the issue with variable scope in a UI Event.
#Define at beginning of script
$hashtable = @{}
$OKButton.Add_Click({$hashtable.SelectedTemplate=$Something})

I am trying to build a basic TCL skeleton script that reads a remote SNMP OID and displays the value on the screen.

I am trying to build a basic TCL skeleton script that reads a remote SNMP OID and displays the value on the screen.
I don't want it to be an EEM Event, I just want to run it from the (tcl)# prompt.
So I guess I'm asking if you can use cli_exec and other commands in the "namespace import ::cisco::eem::*" in a normal non-EEM script - can I do that?
This is the error I get:
OTN.159(tcl)#source flash:TCL_SNMP_Remote_Read.tcl
invalid command name "::cisco::eem::event_register_none"             ^
% Invalid input detected at '^' marker.
What am I missing?
================= TCL_SNMP_Remote_Read.tcl ==============================
::cisco::eem::event_register_none
namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
if [catch {cli_open} RESULT]
    { error $RESULT $errorInfo }
    else { array set cli1 $RESULT }
if [catch {cli_exec $cli1(fd) "snmp get v2c 192.168.1.100 public timeout 1 oid 1.3.6.1.2.1.1.1.0" } RESULT]
       { error $RESULT $errorInfo }
       else { set SnmpSysDesc $RESULT }
if [catch {cli_close $cli1(fd) $cli1(tty_id)} RESULT] {
            error $RESULT $errorInfo
puts $SnmpSysDesc
=========================================================================
In the sho-run config I have:
event manager directory user policy "flash:/"
event manager session cli username "cisco"
Any help to get me started would be greatly appreciated!
Tim

If you don't want an EEM policy, then don't use any of the EEM constructs. Instead, all you need is this:
set output [exec "snmp get v2c 192.168.1.100 public timeout 1 oid 1.3.6.1.2.1.1.1.0"]puts $output

How can I display the value of the Target Currency variable in my query

We have a query which has a key figure set to prompt for a Target Currency at runtime. Because the user did not want the currency displayed in each cell they used the NODIM function to remove it. They do however want to display the Target Currency in a cell within the report. Using Report Designer, I've tried to set up a Text Box to display this value, however, it is not in the list when looking at Constants, Filters or Variables or trying to display it in a Text box. Has anyone found a way to be able to do this?

Hi and thanks for the reply. I should have stated that because this was a validated query, we'd like to do this without modifying the query and thus having to go through another lengthy validation process. That's why we did not go the route of adding Unit to the query but we may have to. Another thing we can do is use a text variable in the headers that displays the currency. That works but, again, it's a query change whereas finding it in Report Designer will not require a query modification.

How to display the values in JSpinner in format day:HH:mm

Hi All,
I want to know how can I display the values inside a JSpinner in the format day:HH:mm. Here the value of 'day' can be anything say from 0 to 365 and HH stand for hour and mm stands for minutes.
I tried to implement it using
mSpinner.setEditor(new JSpinner.DateEditor(mSpinner, "DD:HH:mm"));
but here the values of day was not proper. Please let me know if there is any standard format or how can I configure my own editor.
Thanks,
Rohit.

Hi,
It worked well for 112 as 112 comes under April month.. i.e. it will work properly for the range 91 to 120 as the current month is April and if we start counting from january 01 then for April month , the number of day will fall under range 91 to 120.
See, it will allow you to change the values beyond the limit (i.e. less than 91 or more than 120) but the real problem is that I used this spinner in the table and when I will try to save the value of spinner , then if the value of day in beyond the limit 91 to 120 then it will automatically changing in the range between 91 to 120.
I tried to use format DD:HH:mm ...... do I need to use any other format..
Hi All,

How to write a formula for display the value by group

Post Author: abadugu
CA Forum: Formula
Hi
Could any one please help me on writing the formula for the below senario.
I'm creating Crystal report Via using ClearQuest (IBM tool) since this tool is not supporting subreport function. I'm planning to write a formula.
I have grouped report by request_type field (request_type field contains Validation Defect, Production Defect, Known Defect etc..)
right now my report output is grouped by request_type
ex:
Validation Defect
                     SUMMARY                                                          COMMENTS
Production Defect
                   SUMMARY                                                          COMMENTS
my question was
If request_type = Production Defect display pm_number value field otherwise display null
ex
Production Defect
PM#          SUMMARY                                                       COMMENTS

Display Currency Value of User POV for Entity & Value in Text Box (Header)

I am looking for a function in Financial Reporting Studio that operates the same as the HsCurrency function in Smart View. This would allow batch reports displaying the currency value of the User POV for Entity based on the User POV for Value. Right now I have to have Member Lists for separate reports and different currencies as I am only able to display the Value dimension in the heading of a given report. Users will not be certain of the currency if the Value dimension is <Entity Curr Total>.
I tried the HFMCurrency text function, however the entity is not defined in a Row / Column / Page reference as the entity is determined by the User's Point of View.
Is there a way to display the currency value of a User's Point of View for Entity based on the User's Point of View for Value?
Reference from Oracle Hyperion Smart View for Office, Fusion Edition, User's Guide:
HsCurrency
Data sources: Financial Management, Hyperion Enterprise
HsCurrency retrieves the currency value of the specified dimension member. Entity and Value are the only valid members for the HsCurrency function.
Syntax
HsCurrency (“Connection,Entity;Value”)
Example
In this example, HsCurrency retrieves the entity currency where the currency for the East Sales entity is USD, and the currency for the UKSales entity is GBR. The EastSales entity displays USD, and UKSales displays GBR.
HsCurrency(“Comma”,”Entity#EastRegion.EastSales;Value#<Entity Currency>.”)
HsCurrency(“Comma”,”Entity#EastRegion.UKSales;Value#<Entity Currency>.”)

Null Error in Displaying a value through view attribute

I just want to display a value through message styled text bean from view attribute .
For that i use the code in PR:
But it gives null error: Please any one help me.
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = (OAApplicationModule)pageContext.getApplicationModule(webBean);
OAViewObject vo = (OAViewObject)am.findViewObject("StaffInfoVO1");
if(vo!=null)
OARow row = (OARow)vo.getCurrentRow();
System.out.println("vo is not null");
String str1 = row.getAttribute("FullName").toString();
OAMessageStyledTextBean stext1 = (OAMessageStyledTextBean)webBean.findChildRecursive("RFStaffName");
stext1.setText(str1);
While getattribute("FullName") executed it gives null error. Why?
