Test value of textfield

Hi everyone,
I'm trying to do something that should be really simple, and not getting anywhere with it. Hopefully someone can help out.
We have a simple PDF form that users can fill out and email. When they open it, a text field calculates the current date and fills the field. When the recipient opens it later, the date gets recalculated. So what I want to do is a check on the field.
If the field is empty (as it should be when a user opens the template) I want to put in the current date. If there is something in the field, I don't want to do anything.
I tried the following code in my textfield's initialize procedure:
if ($.rawValue == "") then
$.rawValue = "banana"
else
$.rawValue = num2date(date(), DateFmt(3))
endif
The problem lies in that this never gets to the ELSE case. My best guess is that there is something getting put in as a default by Livecycle. I've tried testing it against null and still the same problem.
Any thoughts?

An even simpler chunk of code that should do the same thing would be this:
if ($.rawValue == "") then
$.rawValue = num2date(date(), DateFmt(3))
endif
A null test gives me the same result of an empty text field, which I find to be rather strange. I can't figure out what it would be as a default value other than an empty string or null, but a test for either always fails.
Any other ideas?

SUMIF to sum only if test-value field is non-blank?

Hey Numbers experts, I'm looking for a way to conditionally sum the values in a column. In other words, if the corresponding field in my "test values" column is blank, I do not want to include the value from the same row in my "sum values" column. Is there a way to do this?
It seems that SUMIF is the perfect function, I just can't figure out a way to make it look for only non-blank fields. the test values, except for the blank fields, are all going to be unique values, so there is really nothing else to use as a test other than the presence or absence of data. Help?
Thanks in advance!

C2=SUMIF(A, "<>"&"", B)
this is shorthand for... select cell C2, then type (or copy and paste from here) the formula:
=SUMIF(A, "<>"&"", B)
the expression:
"<>"&""
reads:
"is not equal to the empty string"

Assignings values to textfields dynamically

Hi,
I am creating table rows & columns containg text fields dynamically as follows:
function addRowToTable()
var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
// if there's no header row in the table, then iteration = lastRow + 1
var iteration = lastRow;
var row = tbl.insertRow(lastRow);
// right cell
var cellRight = row.insertCell(0);
var el = document.createElement('input');
el.type = 'text';
el.name = 'txtRow' + iteration;
el.id = 'txtRow' + iteration;
el.size = 20;
cellRight.appendChild(el);
Now i am calling function addRowToTable() from jsp page as + key is pressed to add rows dynamically.
So as per rows different textfields are also getting created dynamically with different id & name.
Now i am getting session attributes containing the values for textfields from servlet.
but i am not able to map the values for dynamic textfields getting created?
I want to print values in appropriate fields.
Plz help me.

Why don't you just write a for loop within a mehtod that returns an arrayof shapes?

Test value in advanced recordset

HI
In the binding recordset I have a filter looking for a date
matching the URL parameter. In the simple panel, a valid test value
returns normal data.
Unfortunately, testing my web page does not returns any data.
In the advanced panel of the recordset, testing the same
query does not return any data. This is matching the result I have
in the web page.
1) Why the advanced test panel does not require a testing
value.
2) Why the 2 testings does not return the same results.
Thanks

I just ran into this problem too. Am running DW8 with CF8 on

Help needed to extract a value from Textfield

Hi,
I am new to AWT prgramming .
I have created a menu called " Menu System Test window " and it contains toplevel menu item "File" and File Menu contains subitems "Product Evaluation" and "Exit".
When i click File->Product Evaluation it displays a new Frame named "ProductEvaluationMeasurementTool" with some check boxes ,radiobuttons, buttons , text fields.
After compiling the program if i check some check boxes and radiobuttons and press Button1 it displays the result as no of checkboxes checked divided by total no of checkboxes(which i have declared as 18 in my code) in textField1.
I also have textField2 for entering user input.
now my question is after compiling program i check some checkboxes , enter some value in textField2 and press Button2. The result should be diplayed as no of checkboxes checked plus the value added in textField2 divided by total no of checkboxes(which is 18 in my code) . This result should be displayed in textField3.
Can anyone help me?
Thanks in advance

How to display values in textfields obtained from another class

Hi,
Why, oh why, doesn't this work:
When I select a row in my tableClass (consist of a JTable) I want to display these values (strings) in my TextFieldGUI class (consist of just JTextFields). My code looks like this:
TableClass:
public void mouseClicked(java.awt.event.MouseEvent mouseEvent) {
    textFieldGUI = new TextFieldGUI() ;//reference to my textfield class
    gui = new mainGUI() ; //reference to my GUI class
    int tabbedIndex = gui.getSelectedIndex() ;
    int col = tableModel.getColumnCount() ;
    Vector string = new Vector() ;
    String empty = "" ;
    for(int index = 0; index < col ; index++){
        if(table.getValueAt(row, index) == null)
            string.addElement(empty) ;
        else
            string.addElement(table.getValueAt(row, index).toString()) ;
    if(tabbedIndex == 0){
        System.out.println(string) ; //works fine
        textFieldGUI.setTextFieldValues(string) ;
}TextField class:
public void setTextFieldValues(Vector s){
    Vector string = new Vector() ;
    string = s ;
    System.out.println("TextFieldVector: " + string) ; //works fine as well
    String name = "" ;
    String dob = "" ;
    String web = "" ;
    name = string.elementAt(0).toString() ;
    dob = string.elementAt(1).toString() ;
    web = string.elementAt(2).toString() ;
    System.out.println("NAME: " + name +
                       ", BIRTH: " + dob +
                       ", WEB: " + web) ; //values are correctly printed
    txtName.setText(name) ; //writes nothing (empty)
    txtDob.setText(dob) ; //writes nothing (empty)
    txtWeb.setText(web) ; //writes nothing (empty)
}Anyone got a hint on how I should svolve this one?
thanks

Hi
my problem is, for each job_id there is many users. Oh that's something completlty different...
I Strongly Recommand to_
1.*create 2 tables Jobs & users*
2.*create a relation between them* 1 to many to get for each job more than a user that's the way that Must be -- execuse me the bad design of the db pulled u into this trap -
3.then u can deal with it normally no need to a sample code but just a form with Jobs as (Master) and Users as (detail) with a relation and with a simple query u can display each job_id is for many users.
no null values no commas r needed.
Hope this helps...

Adobe Form in HRFORMS: Value of Textfield on Masterpage is not rendered!

Hi all,
I design a new form using HRFORMS. When I put a simple textfield on a master page and give the textfield a default value and render my form using transaction PC00_M01_CALC_SIMU, the value of the textfield is NOT rendered.
I am using Adobe LiveCycle Designer 8.0 within SAP and the Adobe Acrobat 7.0.9 for rendering PDF documents.
The ADS Server Version is: 800.20070708051308.406522
The funny thing is, if you do the same things in Adobe Designer (stand-alone) it works perfectly as it should.
Is this a known bug?
Thanks.
Maik

I have figured out myself.
It is a bug in SAP and has also been reported as a bug to SAP.
It works fine with all Adobe Designer stand-alone versions as well as Adobe LiveCycle Forms Server 7 and 8.
As a workaround in SAP you should use STATIC TEXT with "FLOATING FIELDS" instead of TEXT FIELDS.

thank's
aamir

Hi Gorge,
Are you sure the column you are accessing is of type EditText ?
Please step through your code and do check the type of the column first.
While Rows <= index
Dim o = omatrix.Columns.Item("2000002049").Type 'Check the type here first.
edit1 = oMatrix.Columns.Item("2000002049").Cells.Item(index).Specific
index = index + 1

Compare and test values in two tables

hi everbody, I use oracle 10g
I have a table for large itemsets called L shown below with values
ITEMS CODE
b 1
c 2
d 3
e 4
d:e 5
b:c 6
I generate all candidate combinations firstly 2-sequences for in code field values for that I use below code
select ltrim(replace(sys_connect_by_path(code,','),',',':'),':') comb,level
from L
where level > 1
connect by level =2 ;
some candidate examles generated above code shown belown ( i interest only comb results values )
comb
1:1
1:2
1:3
1:4
1:5
1:6
2:1
2:2
6:1
6:6
I have another table called T2 shown below with some values
TID     ITEM     CID     T_DATE
1     b     1     05.05.1999
1     c     1     05.05.1999
2     e     1     17.05.1999
3     d     2     13.05.1999
4     b     2     19.05.1999
4     c     2     19.05.1999
5     d     2     21.05.1999
6     a     3     07.05.1999
6     b     3     07.05.1999
7     d     3     15.05.1999
7     e     3     15.05.1999
8     b     4     11.05.1999
8     c     4     11.05.1999
9     c     4     16.05.1999
now I want to test every items belong to candidate code generated above with item values of T2 table
in test table T2 is grouped by CID and T_DATE. I want to compare items belong to current code with item of T2 table. if first item(s) in candidate combination is found in T2 table , second item(s) must be found too if there is. but this first and second item(s) together must be found same CID but at different T_DATE belong to that CID. if found, this candidate okey for me.for example we take candidate 3:1. items are d ( code 3 ) and b ( code 1 ) respectively. first item d is searched for CID = 1, it is not found. now we search item d for CID = 2 again , yes it is found in TID=3 row then we look another item b for CID=2 but item b must be found after d row for same CID and at different T_DATE. yes item d is found too for CID=2 after b item at different T_DATE in TID=4 row. that is we wants, is customer ( for example CID 2) buy item b after buying item d same customer at another time as sequence. second example may be candidate 5:6. is customer buy items b and c together ( for code 6) after at another time buying items d and e ( code 5 ) together by same customer
NOTE : I use code field sequence values for pointer of items. items may be used directly on generating candidate process and used comparing process with T2 table
thanks for smart idea....

Testing values in a stack?????

the question I have is how can I pop() strings off a Stack and test the first on with the next one and so on.
I am trying to write a recursive algorithm (push down automana) that recieves a Stack and tests each item in the stack with the next item in the stack. I need to be able to test up to 3 pops.
This is my code. Your expertness is greatly appreciated,
This is for a Grammer checking program.
thanks, steve
public void structureCheck(Stack s, int wordCount, boolean inOrder)throws EmptyStackException{
Stack orderStack = new Stack();
int parseCount =0;
if(inOrder == false){
for(int i=0; i<wordCount;i++){
String temp = ""+s.pop();
if(temp.equals("n")){
temp = "NP*";
orderStack.push(temp);
parseCount++;
structureCheck(orderStack,parseCount,true);
if(inOrder == true){
for(int i=0; i<wordCount; i++){
String temp = ""+s.pop();
String temp2 = temp;
if(temp2.equals("adj") & temp.equals("NP*")){
temp = "";
temp2 = "NP*";
String temp3 = temp2;
String temp4 = temp3;
orderStack.push(temp4);
parseCount++;
System.out.println("parseCount= "+parseCount+" inOrderStack= "+orderStack);
createLayout(true);
}

The program is a grammar and sentence structure program.
1.I am reading a sentence in and tagging the words.
e.g. John ran to the man. --->>>>> noun, verb, det, det, n
2.Put the tagged sentence in a stack ----->>>> stack.push(tagged word)
3.Look for NP so I have to look at eash value and if it is a noun then I have to change the value to a NP*. T
4. Then I run through the stack again and look to see in there is a adjetive is next to a NP* if it is then those 2 words get turned into a NP.
I continuse to run these test until I have a Sentence structure
--------------------------s
--------------------Pred--------NP
---------------det---noun-----ran--home
----------------|-----|--------|-----|
---------------the---man------ran----home
Believe me this isn't trivial. This is my last data Structures program.
This program is to prepare us cor compilers.
I guess they work simular to this.
I have to use recursion because I need to test from the bottom up.

Hello,
i use a bind variable to select only the rows with the same date. (ExecuteWithParams)
Therefor i added the bind Variable as a JTextfield to my client.
If i type the date to the textfield it works, but if i add current date by pressing a button, the filter ignores the value of the textfield.
After a mouseklick into the textfield it works again.
Thank you

Hi,
how do you add the current date? You should set the date in the binding layer if you want it to also show in the textfield. The panelBining variable is a handle to the binding. From here you can cal get("name of the attribute"), cast it to control binding and cal setInputValue

Getting the value of textfield

hi all,
i have dynamically created multiple textfields in a frame.I dont know how to get the valuesin each textfield.Please help me to solve this problem.Very urgent.
Thanks in advance

You can create item inside your LOV region, set the item style to formValue. You can associate this to a View Object field. It can also act as mirror of any other text input field.
FormValue can hold the value and will not be diaplyed to user. You can read value from it controller
example
OAFormValueBean orgValue = (OAFormValueBean)webBean.findChildRecursive("OrgIdFormVal");
Or you can read it fro the VO associated with this form value.

Negative values in textfield

Hello,
I would like to know if it's possible to check the value of a textfield when it is used for numeric values.
I have a form and it should not be possible to enter negative values in the textfields...

Sofie

Hi Sofie,
Yes you can make a Validation process where you use the to_number function. Something like this:
declare
l_num number;
begin
l_num := to_number(:MY_ITEM);
return true;
exception
when others then
return false;
end;
