To develop an error checker for consecutive values

Thanks Doug. Your answer has given me further insight into the problem.
However, I was wondering if it is possible to make an error checker for consecutive values of a particular variable.
That is, the first value and second value might be 100 and 100.5 respectively, but the third value might be 110, which is a wrong value. How do I discard the 110 point from being plotted?
Thanks.

Really difficult. How do you know the first two values aren't errors and
the third one is correct. If you're getting these sorts of values fromn
your A-D hardware, I'd suggest fixing the problem at the source.

How does APEX check for null values in Text Fields on the forms?

Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
Thanks

See SQL report for LIKE SEARCH I have just explained how Select list return value works..

How to check for null values in bpel?? Please Help! very urgent!!!

Hello Guys,
I have a problem. I have an external webservice to which I have to post my request. My task is to create an Webservice and Service Assembly to which others would post request and get response. I have to create SA to deploy onto the bus.
The problem is that there are optional elements in the request and response xsd's. In the Response sometimes certain feilds may come or they may not. for Example:- my response could contain a tag like this <firstName></firstName>
I have to copy these feilds in my bpel process from one variable to another.(like in the mapper).
My Question is , Is there any way in BPEL process or BPEL mapper where I could Check for null values in the request or response???
Your inputs would be very helpful.
Thanks
Rajesh

Thanks for replying man :)
Ok I will be more clear.
Here is a snippet of one of the xsd's that I am using.
<xs:element name="returnUrl" nillable="false" minOccurs="0">
 <xs:annotation>
 <xs:documentation>Partner specifies the return URL to which responses need to be sent to, in case of
Async message model.
</xs:documentation>
 </xs:annotation>
 <xs:simpleType>
 <xs:restriction base="xs:anyURI">
 <xs:maxLength value="300"/>
 <xs:whiteSpace value="collapse"/>
 </xs:restriction>
 </xs:simpleType>
 </xs:element>
This means that the return URL field can be there or it may not be there. But if it is there it cant be null because nillable=false. But the whole <returnURL> </returnURL> can be there or it may not be there because minOccurs=0.
My requirement is , if returnURL is there in the response with a value, then in my BPEL mapper I should map it else I should not map it.
Thats the issue.
and Yes kiran, the node be non-existant.
So can you please help me with this.
Thanks
Rajesh

Checking for null value in arraylist

Hi
i have an excel file which i i am reading into an arraylist row by row but not necesarrily that all columns in the row mite be filled. So how do i check for null values in the array list.
try

                    int emptyRow = 0;

I have tried checking by looping through the ArrayList and then checking for null values like this
if(myRow.get(i)!=null)
// do something
// i have tried this also
if(myRow.get(i)!="")
//do something

From your post I see you are using a 3rd party package to access the Excel SpreadSheets, you will have to look in your API for you 3rd party package and see if there is a method that will identify a blank row, if there is and it does not work, then you have to take that problem up with them. I know this is a pain, but it is the price we pay for 3rd party object use.
In the mean time, you can make a workaround by checking every column in your row and seeing if it is null, or perhaps even better: check and see if the trimmed value of each cell has a lenth of 0.

Error handling for RGB values

Hi
I am having problems doing error handling for RGB values. I have a Java applet with 3 JTextFields whose values are parsed as int variables and stored as ints. If a value is entered that is not a value between 0 and 255 is entered, the appropriate field/s should be set to an empty string.
The problem I am having is that I am using try/catch block to try to parse as an int but then it breaks out of execution completely.
I hope this makes sense and that someone can help.
Thanks!

this is because your code is probably inside one giant try catch block, what you need to do is have small ones in places where you do the parsing.
post code and i can show you how to modify it

Check for NULL value (Recordset field)

Hi y'all...
A little question, so just for the weekend...
I've a query that returns 4 fields, the fisrt three always containing data, and the last one an integer, or NULL. If I get the value with rs.Fields.Item(3).Value.ToString(); it always contains an integer. The NULL values are always converted to '0'.
How can I check if it is a NULL value?

Okey, found a workaround, using the SQL function ISNULL()...
SELECT ISNULL(U_MyVar, 'null_value') FROM [@MyTable]
Now I can check if the value has the value "null_value". If so, that field was null

Adobearm.exe error Checking for updates

I'm getting this error when Adobe Reader 10.1.1 checks for updates. Since it checks automatically this pops up on it's own when you view a PDF. It will also do it if you check for updates using the help menu. Running Windows 7 Enterprise x64. It's also happening on at least one other computer in our organization. I've searched all over, but I'm not finding much on it. I've even gone so far as to run procmon to see if I can see where it's trying to read that it's getting an access denied, but that didn't return anything helpful. Any help is appreciated.

1. adobearm.exe does exist in the location the error states. Interesting it shows an older date on it. Not sure it's getting uninstalled with reader each time. maybe I should delete the arm folder manually when I uninstall and try to reinstall?
2. it has a valid digital signature from Adobe.
3. 1.5.5.0
4. I am admin, but UAC is on. I had also tried running reader as admin, but it made no difference.
5. Doesn't matter if you open stand alone pdf or in browser. You will get the error either way. Without the help menu in the browser I can't manually check for updates, but it appears to check automatically because it will error on it's own when viewing an online pdf.
6. Yes double-clicking on a file you get the error. It's not immediate though. There is a delay before it automatically checks for updates it looks like. Once it does you get the error. I assume it's the checking for updates automatically that causes this anyway since it's the same error when I manually check for updates. I supposed it could be a different problem that produces the same error.
7. originally I installed it via the enterprise download package. I customize the installer using "Adobe Customization Wizard X". When I discovered the problem I rebuilt the package and reinstalled. Didn't help. I then reinstalled using the default Enterprise package with no customization. Didn't help. I then installed off the website. Didn't help.

Authorization checks for filter values

Hi,
I'd need to apply authorization checks to filter values in web reporting. The authorizations should be limited with an attribute of the characteristic, not the characteristic itself.
A practical example:
There are two companies A and B. The companies are not allowed to see any data from each other.
There is a report that displays sales orders. It is used by both companies. The selection of sales orders is limited with the characteristic 'distribution channel', so the initial display is fine.
customer sales order
cust1          so1
cust1          so2
cust2          so3
cust2          so4
Users should be able to filter the sales orders by customer. As filter values, the users should only be able to see and select customers from their own company.
Access to customers should be limited with an attribute of the customer, e.g. company code, because it would be impossible to maintain authorization profiles that contain lists of customers.
However, it seems that BEx and web reports don't care about the authorization restrictions applied to the company code. When a user from company A clicks on the characteristic 'customer' and selects filter values (e.g. with F4), he can choose from all customers.
So, how could we apply authorization checks to filter values?
Message was edited by: Arto Pihlaja

Hi Dirk,
and thanks for your tip!
Unfortunately I haven't yet been able to test it out. Meanwhile, I'll just review the theory and check that I've understood your idea.
Continuing with the customer & sales order example, the report could look something like this:
customer comp. sal.ord.
cust1......A......so1
cust1......A......so2
cust1......A......so3
cust2......A......so4
cust2......A......so5
cust3......A......so6
when a user from company A runs it.
What happens if there is a filter for the characteristic Customer, and the user changes the filter values? What values are displayed as possible filter values? Do you mean that BW limits the values of 'customer' based on authorizations to the attribute 'company'?

Check for null value of an attribute

Hi,
I am reading an attribute using the get_attribute method of the element of a node.
Depending on whether the value of this attribute is initial or not, I need to do some further processing. But the get_attribute method itself is giving an exception that "Access via null reference is not possible". I first need to check if this is initial (or null) and then proceed. Is there some other way to check this value apart from the get_attribute method??
Here is the sample code
IF elem_es_detalhes IS NOT INITIAL.
 DATA:
 item_zzorgas LIKE stru_es_detalhes-zzorgas.
get single attribute
 elem_es_detalhes->get_attribute(
 EXPORTING
 name = `ZZORGAS`
 IMPORTING
 value = item_zzorgas ).
 wd_comp_controller->setleadselectionorgas( EXPORTING i_value = item_zzorgas ).
 ENDIF.
> the get_attribute method is throwing an exception that access via null object reference is not possible.
Please help!!
regards,
Priyank

An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.
How to correct the error
Probably the only way to eliminate the error is to correct the program.
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"OBJECTS_OBJREF_NOT_ASSIGNED" " "
"CL_WDR_CONTEXT_ELEMENT========CP" or "CL_WDR_CONTEXT_ELEMENT========CM006"
"IF_WD_CONTEXT_ELEMENT~GET_ATTRIBUTE"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.

How to check for null value of output parameter?

Hi guys, I get a test procedure with 2 output parameters and do nothing:
CREATE OR REPLACE PACKAGE BODY p_parameters_test AS
PROCEDURE p_null_output_basetype(p1 OUT NUMBER,p2 OUT VARCHAR2)
AS
BEGIN
    DBMS_OUTPUT.PUT_LINE('DO NOTHING');
END p_null_output_basetype;
END;And I have below C# code:
cmd.CommandText = "p_parameters_test.p_null_output_basetype";
OracleParameter p1 = new OracleParameter("p1", OracleDbType.Decimal, System.Data.ParameterDirection.Output);
OracleParameter p2 = new OracleParameter("p2", OracleDbType.Varchar2, System.Data.ParameterDirection.Output);
cmd.Parameters.Add(p1);
cmd.Parameters.Add(p2);
try
    conn.Open();
    cmd.ExecuteNonQuery();
    if (p1.Value==null)
        Console.WriteLine("p1.Value==null");
    else if (Convert.IsDBNull(p1.Value))
        Console.WriteLine("Convert.IsDBNull(p1.Value)");
    else
        Console.WriteLine("p1 else "+p1.Value);
    if (p2.Value==null)
        Console.WriteLine("p2.Value==null");
    else if (Convert.IsDBNull(p2.Value))
        Console.WriteLine("Convert.IsDBNull(p2.Value)");
    else
        Console.WriteLine("p2 else "+p2.Value);
    Console.WriteLine("finished");
catch......The output of it is:
p1 else null
p2 else null
Does anyone have any idea why it always goes to the 'else' of the condition-branching, and how can I check if the output parameter is null?
Thanks in advance.

Morven... I ran into similar problems. Maybe you've found a solution of your own by now, but here's what I've learned...
The Value property of output parameters, like p1 and p2 in your code, actually varies, according to (I think) the OracleDbType of the parameter. You've got OracleDbType.Decimal for p1 and OracleDbType.Varchar2 for p2. These look about right, since they match the parameter types in your actual stored procedure.
After cmd.ExecuteNonQuery() executes, the respective Value properties of p1 and p2 are actually of different types. For p1, it's going to be "OracleDecimal" and for p2 it's "OracleString". Keep in miind that these are the types of the Value property of the OracleParameter objects, not the OracleParameter objects themselves.
OracleDecimal and OracleString (and some other types like OracleDate, etc.) have an "IsNull" property you can use if you cast the Value property to its runtime type...
if ((OracleDecimal)cmd.Parameters["p1"].Value).IsNull) { …do something… }
else { …do something else… }
Or maybe something like this...
Decimal p1val = ((OracleDecimal)cmd.Parameters["p1"].Value).IsNull ? 0 : ((OracleDecimal)cmd.Parameters["AVG_SALARY"].Value).Value;
I'll admit that expressions like this: ((OracleDecimal)cmd.Parameters["AVG_SALARY"].Value).Value look a little weird. But the "Value" of the "OracleDecimal" property is a regular .NET decimal type (System.Decimal). So, it's a "Value" of the "Value" property of the OracleParameter class.
Even when the stored procedure returns a null, the Value property is still populated. In the case of p1, it's populated with an OracleDecimal object (actually a struct) where IsNull is true. That's why "p1.Value==null" tests false.
From what I can see, OracleDecimal, OracleString, etc. will never be typed as DbNull, or DBNull.Value. So, that would be why Convert.IsDBNull(p1.Value)) always returns false. btw, it appears that these are Value types. That would suggest that coding something like like this, should be avoided…
OracleString p2val = ((OracleString)cmd.Parameters["p2"].Value;
if (p2val.IsNull) { …do something… }
else { …do something else… }
By assigning the value to another variable, you’d be actually creating an entire copy of the OracleString structure, which is pointless.
I hope that helps
