Multiple variable initialization using arrays
Hi,
In my program I want to initialize some 20 odd variables(all of the same type) to the same value having their names as Input1, Input 2 .. Input 20. Want I want to do is to use an array to do this rather than writing the 20 variables one after the other. Is there any way to do so ?
Please help.
Thanx in advance,
Gaurav
Hi Again,
I am sorry for framing the question wrongly. What i want exactly is this :
I want to create a variable no. of arrays (the number of arrays will be inputed by the user). I want to initialize them ,something like this
int Input1 [] = new int [400];
int Input2 [] = new int [400];
After this initialization I will then fill these with some info. from a file and then use it in my program.
So I want to use a for loop or some other loop so that I can achieve this.
Please help,
Thanks
Gaurav

Using array binding to perform multiple rowupdates in one pass
For the first time I am attempting to use array binding in VB.NET to update multiple rows via a single execution of a stored procedure. My subroutine is:
Friend Sub UpdateSolutionStatusUsingArrays(ByVal intNumBeingUpdated As Integer, ByVal arrScenarioID() As Integer, ByVal arrSolutionID() As Integer, ByVal arrInOrOut() As Integer, ByVal arrTimePeriod() As Integer)
Try
'Set up the Command object
Dim cmdUpdateSolutionStatus As OracleCommand
cmdUpdateSolutionStatus = New OracleCommand
cmdUpdateSolutionStatus.CommandType = CommandType.StoredProcedure
cmdUpdateSolutionStatus.CommandText = "ProcUpdateSolutionStatus"
cmdUpdateSolutionStatus.Connection = cnnORACLE
cmdUpdateSolutionStatus.ArrayBindCount = intNumBeingUpdated - 1
cmdUpdateSolutionStatus.CommandTimeout = CInt(tblOptions.Rows(intDatabaseIndex).Item("ConnectionTimeout"))
'Add ScenarioID array as parameter
Dim p_ScenarioID As New OracleParameter("ScenarioID", OracleDbType.Int32)
p_ScenarioID.Direction = ParameterDirection.Input
p_ScenarioID.Value = arrScenarioID
cmdUpdateSolutionStatus.Parameters.Add(p_ScenarioID)
'Add SolutionID array as parameter
Dim p_SolutionID As New OracleParameter("SolutionID", OracleDbType.Int32)
p_SolutionID.Direction = ParameterDirection.Input
p_SolutionID.Value = arrSolutionID
cmdUpdateSolutionStatus.Parameters.Add(p_SolutionID)
'Add InOrOut array as parameter
Dim p_InOrOut As New OracleParameter("InOrOut", OracleDbType.Int32)
p_InOrOut.Direction = ParameterDirection.Input
p_InOrOut.Value = arrInOrOut
cmdUpdateSolutionStatus.Parameters.Add(p_InOrOut)
'Add TimePeriod array as parameter
Dim p_TimePeriod As New OracleParameter("TimePeriod", OracleDbType.Int32)
p_TimePeriod.Direction = ParameterDirection.Input
p_TimePeriod.Value = arrTimePeriod
cmdUpdateSolutionStatus.Parameters.Add(p_TimePeriod)
'Open connection
cnnORACLE.Open()
'Run stored procedure
cmdUpdateSolutionStatus.ExecuteNonQuery()
'Tidy up
cmdUpdateSolutionStatus = Nothing
cnnORACLE.Close()
Catch ex As Exception
WriteLog("Subroutine UpdateSolutionStatusUsingArrays:" & ex.Message.ToString)
strState = "Error"
'Update Run Status to show error has occurred
cnnORACLE.Close()
UpdateRunStatusORACLE(7)
End Try
End Sub
When the routine tries to run cmdUpdateSolutionStatus.ExecuteNonQuery() I get the error message:
Unable to cast object of type 'System.Int32[]' to type 'System.IConvertible'.
I have tried all sorts of variants of the code but with no success. The arrays are being set up correctly. Anyoneone know what I'm missing?
StewartTry declaring the arrays as OracleNumber datatype instead of Integer. I've had this issue before, and I believe this is what I did to solve the problem.

First, I would like to thank everyone in this forum for all the help they have given me over the past few weeks. With that said, I am currently trying to alter the following code to accept and use arrays to end to produce three seperate results. The program now as three hard coded variables which are
Amount = 200000.00;
Term = 30;
InterestRate = .0575;
I need to have the program work the same, but produce results for three different Terms and Three different periods. Below is the code the I am working on, I have added two arrays containing the required information. I am having a hard time coming up with a for statment to move the program through the two arrays. Any pushes in the right direction would be great. I left the hard code variable in place, I know that I do need to remove them and alter the equations. I just thought it would be easier for everyone to understand if I left the code in working form.

Can a session variable be an array?
I have a dynamic list which may have multiple values
selected. I can capture the resulting array in a $_POST variable.
Using the Insert Record behavior, I cannot cause the $_POST
variables to be sent to the redirect page unless I use session
variables. Can a session variable be defined as an array? If so,
how do I declare it as an array and how do I move the form variable
array to a session variable array? If it can't be an array, how do
I define the target variables for 0 to x items from a form variable
array?I can't answer specifically for PHP but in the other
languages as session
variable is basically a holding place for a value. As a comma
is a valid
character then if you have a comma delimited list (which is
what a form give
you if multiple items are selected) then you simple assign it
to the session
variable and it will be stored as such.

Local variable for an Array of fixed size
Hello,
I have a two multirate loops in a VI.
In one loop, I want to refer an fixed sized array initialized in the other loop.
But I coudn't name the array, so I can't refer it.
Is there any way to refer it?
Thanks,
Young.If you need a local variable, there is no other way than to create an indicator for it.
In LabVIEW there is no "fixed length" array : you can always add or remove an array element, and you don't need to declare it as in other languages. They are intrinsic dynamic objcets. Of course, the memory manager has to cope with this, that's why it's often better to initialize an array, to give it its final size immediately, resulting in faster running programs. However, this is only noticeable with relatively large arrays (> 10000-100000 elements).
May be you should explain in more details what you intend to do, because trying to reproduce a C approach in LV is probably not the best thing to do. For instance, you said that you are initializing your array in a first loop. You mean that you re-initialize the array at each iteration ? I suppose no, so may be you could put the initialize step out of the loop, and wire the array to your two parallel loops.
Remember also that local variables are not always good programming solutions, since using them will generate copies of their content each time they are refered to. And that can low down your program very significantly...

Message variable initialization
Hello,
We had this ridiculous situation a while ago where out service instances create their variables with multiple nodes.
For example if we have xsd looking like this:
<element name="Response">
<complexType>
<sequence>
<element name="Result">
<simpleType>
<restriction base="string">
<enumeration value="OK"/>
<enumeration value="ERR"/>
</restriction>
</simpleType>
</element>
<element name="Comment" minOccurs="0" type="string"/>
</sequence>
</complexType>
</element>
In BPEL we have message variable which part is this "Response" element. Everything is fine till the moment we start getting initial variable looking like this:
<outputVariable>
<part name="payload" >
<Response>
<Result/>
<Result/>
<Result/>
<Result/>
<Result/>
<Result/>
</Response>
</part>
</outputVariable>
Of course we have no reason for this, no logs, no info and so on. Any idea anyone?
Everything is normal concerning the BPEL, no errors are raised till the moment we need to populate the variable. The process is working correctly but we cannot return result to the caller.
WL version: 10.3.5.0
SOA version: 11.1.1.5.0
BPEL version: 2.0
Best regards.could you please send your test case to our support team? this doesn't look right. bpel engine would initialize the variable based on the xpath usage in to-spec expressions. you can try turning of variable initialization for that particular component using bpel.config.initializeVariables to false. and go with literal xml variable initiation. [http://docs.oasis-open.org/wsbpel/2.0/OS/wsbpel-v2.0-OS.html#SA00038]
http://docs.oracle.com/cd/E28271_01/dev.1111/e10224/bp_manipdoc.htm#BABHDFBJ
here is the sample for that property
in composite.xml, find the component, under that component add this property, and re-deploy with your literal variable init.
<property name="bpel.config.initializeVariables">false</property> -
Combined declaration and initialization of array
Hello All,
What is the difference between the below mentioned arrat initializations?
int myArray[]=new int[] {1,2,3,4,5};
int myArray[]={1,2,3,4,5};
but both of them behaves in same way.
Regards
SojanThe first creates an anonymous array and copies its reference in the variable myArray. The second implicitly creates and initializes an array (there isn't really a perceptible difference). However, the second can only be used in declarations. Consider the following:
int[] iArray = {1, 2, 3};
iArray = new int[] {9, 8, 7}; // works
iArray = {9, 8, 7}; // doesn't work !!!Hope this helps,

Hello!
I'm doing a program which works with arrays. I use initialize block arrays to create them. But it depends on other variables the dimension of these arrays. If I want to change the length of a dimension I wire a variable to the block, but I have no idea what can I wire to the block to modify the number of dimensions....it cannot be modify when the program is running?? How I have to do modify the number of dimensions depends on a variable?
Thank you in advance!
LarsonThe initialize array function is a growable function, that is it changes the function inputs by dragging the dimensions not programatically. There is a work around, you can use a case structure to call different versions of the function. This will work but will only for a finite number of cases. The other way is to initialize a multidimensional array as a single dimension and then pass it to the resize array function, i.e initialize ARRAY[i*j*k] and resize to ARRAY[i][j][k]. This is a little unusual to deal with arrays which change at runtime. The final approach it to write polymorphic functions to handle the different cases, again you will not have full dynamic run-time handling of all possible cases but can handle a few cases easily.

How to delete multiple variables from the variables list
Hello,
Iam using FrameMaker 9.0. Is there a way I can select multiple variables from the book and delete them together.
Thanks,
CP.NO in FM9. Take SQUIDDS TOOLBOX the free tool: 'Formats'
'Formats' is a very helpful tool for 'deleting' paragraph formats, character formats, cross reference formats, table formats, color definitions and variables.
You can delete unused one or all formats of selected. For paragraph and character you can also decide to 'add new one in catalog'.

Hi All,
Culd you please tell me where I can declare a global variable as an array in PI 7.1.
In PI 7.O we used to store global variables in java sections and it was recognized across mapping in message mapping
In PI 7.1 I have declared a variable in init function in functions tab in message mapping but its not recognized in my mapping.
Could you please help me with this?
Where I have to declare a global variable so that I can use it anywhere in mapping?

How do I initialize an array after getting xml data via httpservice?

result="icdcodesService_resultHandler(event)" showBusyCursor="true" />
(I have tried resultFormat using object, array, xml).
I am using this following Tour de Flex example as the base -http://www.adobe.com/devnet-archive/flex/tourdeflex/web/#docIndex=0;illustIndex=1;sampleId =70500
and updating it with the httpservice call and result handler. But I cannot get the data to appear - I get [object Object] instead. In my result handler code I use "icdcodesar = new Array(event.result.Root.Row);" and then "icdcodesar.refresh();".
The key question is: How to I get data from an external xml file into an array without getting [object Object] when referencing the array entries. Thanks much!

The first initial shoulld be initialized to '*' and the secind initial should be initialized to '@'. Both initials should be 30 characters high and 30 characters wide and the initials should also represent the uppercase letter of your initials. I know that the first initial's matrix needs to be filled up vertically and the second initial needs to be filled horizontally but the output is wrong....PLease Help!

Hello guys,
Is there anybody know how and when java checks for variable initialization?For example if we change a value, assume a without initializing it we get variable a might not have been initialized.I wish to know how java checks that the variable is already assigned or not.
int a;
a++;//How java checks this
regards,
HaddockRules is:
To variables of instance - It's default value attribute automatically if not initialize with value.
To local variable (methods for example) - It's default value in initialization has been MUST attributed
Instance variables has a folliwing default value:
class A{
int i; //default value is 0
char c; //default value is '\u0000'
byte b; //default value is 0
short s; //default value is 0
long l; //default value is 0
float f; //default value is 0.0
double d; //default value is 0.0
boolean bl; //default value is false
String str; //Object is always null
int x[]; // null. It's Object's array
int x[5]; // 5 times default value 0.
void testInitializeValue(){
int x; // Compiler error; This variable has been initialized
if(x == 5){
return;
Ok..Thanks!!
