How do I let user enter a number?

how do I let user enter a number?Any method or proccess.Plz help.

On the command line you can use:
BufferedReader in = new BufferedReader(new InputStreadReader(System.in));
String line = in.readLine(); // characters so far
int number = Integer.parseInt(line);Notify that if the user enters something different from a number an exception in thrown. In that case you should possibly ask him again.
In swing applications of applets you would do it different.

How do I let user enter a primary key value on a form

I'm creating my first APEX application. I have a simple table called HOSTS with 2 columns HOSTNAME and IP_ADDRESS. HOSTNAME is the primary key for the table. HOSTNAME is a perfectly acceptable primary key and I don’t wish to create an additional column to be populated by a sequence.
What are my options for creating a form on the table without using "Existing trigger", "Custom PL/SQL function" or "Existing Sequence" to populate the primary key column, i.e. HOSTNAME, so that the user can enter a value for the primary key?
Any assistance greatly appreciated.
Gavin

The debate about natural keys versus surrogate keys
will no doubt continue with advocates for both sides.
However there is also a difference between
'making your life easier' for APEX development and
'making your life more difficult' by having to
analyse, implement and deploy a surrogate key only
approach to an existing database which employs both
natural keys and surrogate keys.
hould we be forced to change the database design
because a development tool does not cater for natural
primary keys?The application development product is TRYING to save you from shooting yourself in the foot. The idea is to separate the primary key from being accessed by the user or ANY carbon based unit.. The key is mainly used by the system to join and lookup data rows, not for people to change whenever they decide that the key is WRONG.
Think about this, if you use Last Name as a key in your system (a bad idea to begin with since this is NOT a unique id when you have two Smiths). When a person needs to change this because Jimmy Smith is NOT the only Smith working for Acme Toys, you have to cascade that change through all the child tables related to the main person table.
If instead you use a system generated key, no change will be required since the key has NO relation to the data other than it represents a pointer to that row of data.
Works for me, since I do not want to write all the supporting code when APEX builds it for you...
Thank you,

How to keep a calculation field blank until the user enters a number?

I am building a sales sheet for a school that sells scrip as a fund-raiser. I have the document set so that when the user enters the number of scrip certificates he wants (say, two $25 gift certificates at Lowe's), the program will automatically calculate that this user owes $50 for that scrip category. However, there are more than 100 companies that one can choose from, and if the user doesn't enter a number, the calculated field shows $0. Is there a way that each field can stay blank until the user enters a number bigger than zero? By the way, I'm using this calculation to determine the value (borrowed from a user on this forum): event.value = 50 * this.getField("Lowes").value
Thanks!

There are two approaches. You can either add the following Validate script:
// Custom Validate script for calculated field
if (+event.value !== 0) event.value = "";
Or you can change your custom Calculate script and set the Format type of the field to "None":
// Custom Calculate script
(function () {
var v = +getField("Lowes").value;
event.value = (v !== 0) ? util.printf("$%.2f", v) : "";

How to get the user entered data?

Hi all,
I have created an HTMLB DynPage component.
In That i have created my input screen with textboxes using response.write method.
i have added one onConfirm event on which the data whould validate.
so onConfirm method im trying to get the data with request.getParameter method which returns null...
how to do...how to get the user entered data to do my validations...can anyone plz advice.
Thanks,
Viswes

Hi
inputfield or textbox component entered directly using response.write(...) are not htmlb , but html.
to create portal input field (ie HTMLB), you should do something like
this in the doProcessBeforeOutput member function
InputField field1 = new InputField("Id1");
field1.setSize(8); // 8 characters
this.getForm().addComponent(field1);
and in doProcessAfterInput member function
InputField field1 =
(InputField) this.getComponentByName("Id1");
you can then manipulate the content of the field.
Hope this help,
Guillaume

How to differentiate whether user entered '0' or no value in the parameter?

I need some clarification.On my selection screen I have 4 parameters( P_QTYLL,P_QTYUL,P_AMTLL,P_AMTUL). I have to check the values entered by the user in those fields and I have to display the user entered values in the next screen.My problem is if the user enters '0'(in any of the above fields) means '0' has to displayed in the next screen.But if he enters nothing means then nothing has to be displayed in the next screen.My problem is I am checking for '0', against the values(initial,'',space,0) for user entered value.But I am unable to differentiate the '0' and nothing(no value) even though I checked against the values(initial,'',space,'0').All the 4 conditions are treating both the '0' and 'novalue' the same.How to differentiate whether user entered '0' or entered nothing(no value).
for example below is my code
IF P_QTYLL EQ 0.
P_QTY_LL = P_QTYLL.
ENDIF.
IF P_QTYUL EQ 0.
P_QTY_UL = P_QTYUL.
ENDIF.
IF P_AMTLL EQ 0.
P_AMTLL_S = 0.
ENDIF.
IF P_AMTUL EQ 0.
P_AMTUL_S = 0.
ENDIF.
IF P_QTYLL EQ ''.
P_QTY_LL = ' '.
ENDIF.
IF P_QTYUL EQ ' '.
P_QTY_UL = ' '.
ENDIF.
IF P_AMTLL EQ ' '.
P_AMTLL_S = ' '.
ENDIF.
IF P_AMTUL EQ ' '.
P_AMTUL_S = ' '.
ENDIF.
LIKE THE ABOVE I checked against the values space,initial.But using those I am not getting any difference for no value and '0' .All the four values(space,initial,'0','') are treating both the '0' and no value in the same way.
Thanks,
Balaji

hi,
you said your teamlead doesn't want the type to be changed to 'C'.so try adding one dummy variable of type c and pass your parameters value to this dummy variable and check dummy variable for value '0'.
eg:
Data DUMMY(11) type c.
DUMMY = P_QTYLL.
IF DUMMY EQ 0.
P_QTY_LL = P_QTYLL.
ENDIF.
DUMMY = P_QTYUL
IF DUMMY EQ 0.
P_QTY_UL = P_QTYUL.
ENDIF.
i think this will help you 2 some extend.

How do I make form or table where certain numbers update according to a formula when the user enters one number?

Hi, I am an amature website designer and have made a website
using dreamweaver. I am very lost when it comes to doing tougher
things in dreamweaver. I want to create a small form or a table
where there will be 7 or so numbers that are generated based on
simple formulas for each one once you enter one number. Can someone
please help me with this task whether it is in dreamweaver or even
making it out of flash or anyway that this would be the easiest to
make possible. Thanks

Here's a very simple form you could use to perform a
calculation, it this case, squares the input value and writes it
back to another input field... Hopefully you can use this as a
pattern to apply your own algorithm. You'll need to do validation
to assure the entered fields are appropriate for the calculation
(required fields are entered).
Hope this gets you started.

How do i let users modify patch lists?

I'm designing an application in which the user needs to create and modify patches. I would like the interface to have a list of user patches, followed by sliders an textual input boxes to modify parameters. I am aware that i could easily put together the interface with Core Data, however, i don't need a lot of the data management features of Core Data, and would like a simpler way to create mutable lists. Can someone please explain how I could do this?

Can NSDictionary hold multiple values for one key, or do i create multiple dictionaries with the same keys? I am still not very familiar with the NSKeyedArchiver and it's subclasses.

Is it possible to let user restrict the number of the records in OVS?

is it pissible ?
For example a user can input 500 record .....
Then when we search and we can get the value set by the user '500' so we can restrict our record in our application.
Best regards,
Anders

Dear Anders,
u can have an i/p field (say var) for the user where he can specify the no. of records and u can use the following logic.
TYPES: BEGIN OF ST_BOQ,
          ITEMNO       TYPE ZITEMNO,
          MATNR        TYPE MATNR,
          MAKTX_P      TYPE ZPOTEXT,
           SRNO         TYPE ZSERIALNO,
       END OF ST_BOQ.
DATA: IT_BOQ TYPE TABLE OF ST_BOQ,
      WA_BOQ LIKE LINE OF IT_BOQ.
data: var1 type i.
var1 = 10.
        SELECT * FROM ZBOQ_ITEM UP TO var1 rows INTO CORRESPONDING FIELDS OF TABLE IT_BOQ .

How can I create User Entered Additional Data Points in Credit Management?

I currently have a requirement to create additional data points in Credit Management (11i) that require a data analyst to input the value so that the score can be calculated.
For example: Does customer have a Qualified Audit Report?
If YES = +10 points added to score
If NO = 0 points added to score
I was able to add an additional data point and the case folder was assigned to an analyst, however when opening the case folder to input the missing data, the additional datapoint was not included in the case folder. Does anyone know what I may have missed in the setup?
Data Point was defined as follows and added to a checklist called TEST.
Data point: Unqualified
Category: (none)
Parent: (none)
Application: Receivables
Scoreable: Y
Enabled: Y
PL/SQL Package: (none)
Function: (none)
Thanks in advance.
Shauna
Edited by: sphelps on Sep 22, 2011 8:29 AM

The setup described above was correct. The datapoints did not show up in the case folder until the next day. I am assuming that maybe the changes required a bounce or a background process of some sort.
