Creating Type void

cpsSend( const void* Message, Const int
BCount)
I have created the VI for the above function. I am having problem finding the right pallate that will make "Const Void* Message" when i am in the
-Build Application or shared library
- Define VI Prototype(function Prototype)
I have tried to use the variant function in my VI but i am not getting "const void". Also is there a way to have a parameter of type int instead of a long, short or etc. I change the properties to the controls/indicators to u32, I32 and etc. If you can direct me to a tutorial or the instruction on how to implement this i would really appreciate. Thanks for your time.

The const keyword is only a hint to a C compiler that the function is not modifying the buffer past in in any way. This allows a C compiler to do some optimizations in certain circumstances when calling such a function and when compiling the function any well behaved compiler should complain if you modify this pointer inside the function or pass it to a function which is not itself declared to treat this pointer as const. For LabVIEWs Call Library Node you can fully ignore this keyword.
The void* pointer is a C syntax for a pointer which can potentially point to any datatype. In LabVIEW you will have to find out what the datatype is, this pointer should point at. It could be a byte, short, integer, long, or floating point value or an array of them or maybe also a string and configure the Call Library Node accordingly. LabVIEW is a strict datatype language and does not really allow for ambigues datatypes such as void* do present. This is no problem as the function in question will expect some specific datatype anyhow, possibly depending on a second parameter which defines what datatype the void* parameter should be treated as in this case.

1067: Implicit coercion of a value of type void to an unrelated type mx.collections:ArrayCollection.

Here is what I have going on.
When a button in my app is clicked it will instantiate a new object called ButtonCommand, within that object I create a new instance of a ListVO called vo. I then reference my model object that also has a separate instance of the same Value Object ListVO class, reference its properties and place it into the corresponding property of the new VO object. Here is the code.
var vo:ListVO = new ListVO();
vo.name = model.list.name;
vo.id = model.list.id;
vo.amount = model.list.amount;
vo.category = model.list.category;
Within that same ButtonCommand class, next line I am trying to add the new ListVO instance to an arrayCollection that is also referenced from my model object, so here is the code for that.
model.listCollection = model.listCollection.addItem(vo);
I get the following error : -1067: Implicit coercion of a value of type void to an unrelated type mx.collections:ArrayCollection.
And here is my getter/setter for the model.listCollection.
public function get listCollection ():ArrayCollection
      return _listCollection;
public function set listCollection(value:ArrayCollection):void
      _listCollection = value;
Any Ideas?

I thought model.listCollection is an ArrayCollection?
model.listCollection is an ArrayCollection as shown in the example model code a few posts back.
public class Model extends Actor
     //- PROPERTIES - //
     //-- other properties are here
     private var _listCollection:ArrayCollection = new ArrayCollection();
     public function Model()
     super();
     //other getter and setters here
     public function get listCollection ():ArrayCollection
     return _listCollection;
     public function set listCollection(value:ArrayCollection):void
     _listCollection = value;
I am finding this to be very odd, seems like a simple getter setter situation, but I feel I must be missing something. The code trace(model.listCollection); should trace out as an ArrayCollection and not the VO object I am trying to add to it. Also when i run the code model.listCollection.addItem(vo); it should add the vo to the array collection through my setter, but yet it seems to try to access my getter.
I took Kglads advice and traced out _listCollection within my getter before my return statement and it returns [object ListVO]..... confused for sure. I am going to change the _listCollection property in the model from private with a getter/setter to a public and see what happens.

1067: Implicit coercion of a value of type void to an unrelated type Array.

        public function Helicopter (stageRef:Stage) : void
            this.stageRef =stageRef;
            addEventListener(Event.ENTER_FRAME, loop, false, 0, true);
            addEventListener(Event.ENTER_FRAME, Backdrop);
            key = new KeyObject(stageRef);
            x = stageRef.stageWidth/2;
            y = stageRef.stageHeight/2;
I'm basically having the following error:
1067: Implicit coercion of a value of type void to an unrelated type Array.
In relation to the event listener that calls 'Backdrop'. Backdrop is a public function in another class, but it does still recognise Backdrop as a function. Any ideas on what might be causing the error?

there's no Backdrop method there. and, if you're importing your Backdrop class, you can't use a Backdrop method. i don't know what you're trying to do but if you're trying to create a Backdrop instance use the following:

Wsimport Creates a Void operation in PortType - Help Needed Urgently!

Hi,
I've been pulling my hair out over this thing for days now. It must be something really trivial which i'm missing.
I have a very simple WSDL (see below). I'm trying to generate the client for it. I'm using netbeans client which is running wsimport. However instead of getting a port type which gets a parameter and return value, it creates a void operation and the input parameter is of some Holder type.
This is the WSDL:_
<?xml version="1.0" encoding="UTF-8"?>
<definitions name="SampleWSDL" targetNamespace="http://j2ee.netbeans.org/wsdl/SampleWSDL"
xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://j2ee.netbeans.org/wsdl/SampleWSDL" xmlns:plnk="http://docs.oasis-open.org/wsbpel/2.0/plnktype" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
<types/>
<message name="SampleWSDLOperationRequest">

</message>
<message name="SampleWSDLOperationResponse">
<part name="part1" type="xsd:string"/>
</message>
<portType name="SampleWSDLPortType">
<operation name="SampleWSDLOperation">
<input name="input1" message="tns:SampleWSDLOperationRequest"/>
<output name="output1" message="tns:SampleWSDLOperationResponse"/>
</operation>
</portType>
<binding name="SampleWSDLBinding" type="tns:SampleWSDLPortType">

<operation name="SampleWSDLOperation">

<input name="input1">

</input>
<output name="output1">
<soap:body use="literal" namespace="http://j2ee.netbeans.org/wsdl/SampleWSDL"/>
</output>
</operation>
</binding>
<service name="SampleWSDLService">
<port name="SampleWSDLPort" binding="tns:SampleWSDLBinding">
<soap:address location="http://localhost:${HttpDefaultPort}/SampleWSDLService/SampleWSDLPort"/>
</port>
</service>
<plnk:partnerLinkType name="SampleWSDL">
<plnk:role name="SampleWSDLPortTypeRole" portType="tns:SampleWSDLPortType"/>
</plnk:partnerLinkType>
</definitions>
The generated code for porttype:
@WebService(name = "SampleWSDLPortType", targetNamespace = "http://j2ee.netbeans.org/wsdl/SampleWSDL")
@SOAPBinding(style = SOAPBinding.Style.RPC)
@XmlSeeAlso({
ObjectFactory.class
public interface SampleWSDLPortType {
@WebMethod(operationName = "SampleWSDLOperation")
public void sampleWSDLPortTypeOperation(
@WebParam(name = "part1", mode = WebParam.Mode.INOUT, partName = "part1")
Holder<String> part1);
So the question is why on earth does wsimport create the port type with this Holder type and the void return value when the WSDL is a request-response type of wsdl with RPC, soap binding, string in string out?
Please help a brother...

Amazingly enough - the reason was that I didn't change the part names in the wsdl from the given defaults: I left it part1 for the input and part1 for the output - it's not so much about leaving the defaults as much as it is about the input and the output having the same name. When changing the part1 in the input to "input" and the part1 in the output to "output" it all works fine.
Thank God.

Create type not working

I'm following the 8.1.6 documentation to create type, but it always returns me the error.
My references are from :
http://technet.oracle.com/docs/products/oracle8i/doc_library/817_doc/appdev.817/a76976/adobjmng.htm
The script is:
CREATE TYPE location (
building_no NUMBER,
city VARCHAR2(40) );
The error is:
1/15 PLS-00103: Encountered the symbol "(" when expecting one of the following:

4/0 PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following:

May I know that how can I work around it?
I had tried earlier another syntex successfully:
create type typeName as object(definition....).
May I also know what's the difference between these 2 commands?
Thanks in advance
Minny

I think there's a mistake in the documentation. I may be wrong but I think it should always be CREATE TYPE x AS OBJECT (...)

Creating Types and Internal table

Hi,
I created
Types: begin of itab,
           field 1 ...
            Field 30,
        End of itab.
Data: lt_itab type table of itab.
I need to create a second type itab1 with all the itab fields and also new fields field31 and field32.
I dont want to declare all the 30 fields again for the second one.
Can any one tell me how to create this?
Thanks.
rajesh

You can INCLUDE TYPE.
Types: begin of itab,
       field1 type string,
       field2 type string,
*      More Fields in here.
       Field30 type string,
       End of itab.
Data: lt_itab type table of itab.
TYPES BEGIN OF new_itab.
       INCLUDE type itab.
TYPES: field31 type string,
       field32 type string,
END OF new_itab.

Create TYPE

I am not able to create type objects tried with different versions of oracle too.
Currently I am using Oracle 11g Enterprise edition (2.9GB).
The problem is when i create a TYPE object and when i terminate the command with a semicolon ';',oracle sql does not stop only (the query does not execute) the loop goes on and on.
I did like this and found that the SYNTAX is also perfect.
SQL> CREATE TYPE address_type AS OBJECT
2 (street varchar2(30),
3 city varchar2(30),
4 pincode number(10));
5

It goes on and on it never ends. Command never executes.
Please Help!

end the command with "/" :

A type body will contain PL/SQL semicolons, so once SQL*Plus sees that you're entering a type it stops treating semicolons as the SQL*Plus multi-line statement terminator character. (A type header will not contain semicolons, but I expect Oracle decided it would be even more confusing if CREATE TYPE BODY behaved differently to CREATE TYPE.)
Note you can also terminate entry by entering a dot (period) on a line on its own.
I guess in older version there was nothing like that.Actually this has been around for over 10 years ;)

Create Type as Object not working in linux oracle 11g

Pleae refer to the following simple create type as object statement.
CREATE OR REPLACE TYPE EC_VIEWABLETYPES as object ( CASE_TYPE_ID NUMBER)
It is working in oracle 11g and windows server 2008 environment.
But it is not working in oracle 11g with linux environment.
I am executing this statement as dynamic sql as follows
CREATE OR REPLACE PROCEDURE TEMP_SP

COMMIT;
RETURN;
END;
END;
exec TEMP_SP
please let me know what i am missing ?

And error is:ORA-00600: internal error code, arguments: [kothc_uc_md5:lxerr], [], [], [], [], [], [], [], [], [], [], []

I think you cannot create types if the attributes' datatypes are based on package records, constants, etc
See:

is

end val;
Package created.

In that case, why don't you create the same type as seen in utl_http as an object in the schema?:
TYPE req IS RECORD (
url VARCHAR2(32767 byte), -- Requested URL
method VARCHAR2(64), -- Requested method
http_version VARCHAR2(64), -- Requested HTTP version

How do I create a void in a power plane?

I want to remove an area of copper from a power plane but can't work out how to do this.
I'm sure it's obvious if you know how!
Please could a kind soul point me in the right direction?
Thanks
Dave

Hi David:
If the delete island way works, that's great. Still, I think I'm either not explaining my solution correctly or understanding the problem you're describing. Even if it doesn't help you, it might help others, so I'll describe with an example.
The example I'm describing is attached below.
There are three nets (GND, 1, and 2) in the example, and two parts. The two parts are connected by nets 1 and 2 and GND is assigned to the power plane. Once I placed the power plane, I setup the groups and keep out to create the void.
1. Place > Keep-in/Keep-out Area. Draw the area where you want the void. You will have DRC errors at this point, and we will now remove them.
2. We need to assign the net GND to a net group so it can be associated with the Keep-out area. Tools > Group Editor. On the Net Groups tab, click Add, and create a
new group GROUP_GND. Then assign only net GND to the group.
3. Select the Keep-in/keep-out layer in the design toolbox. (The selection filter can be set to Enable Selecting Other Objects). Select the Keep-out area, then Edit > Properties. The Keep-in/keep-out properties should show. On the Keep-in/keep-out tab, check the box next to Net Group. Then click the Options... button beside Net Group. Uncheck All Groups at the bottom, and check GROUP_GND. Click OK, click OK.
4. The DRC errors should be gone because the keep-out only applies to net group GROUP_GND.
I hope this explanation clears up my ambiguity from before, even if it doesn't help in the end.

SQL 3 : Create type

hello,
in an example using the object-relational model
I created the following type:
create type professeur_t as object (

+     nomp varchar2(20),+
+     nbg integer);+
+     /+
create type "professeurs_t" as table of professeur_t;
create type eleve_t as object (

+     nome varchar2(25),+
+     nomc varchar2(5)+
+     );+
+     /+
create type "eleves_t" as table of eleve_t;
when I try to create another type with the following command
create type ecole1_t as object (
+     nomc varchar2(5),+
+     eleves eleves_t,+
+     professeurs professeurs_t );+
+     /+
I get the following error message:
Warning: Type created with compilation errors
checking with:

I get:

Please if you have an idea about what to do? help me ?
Thank you in advance

Hi,
If you enclose the name of a type (or a table, or a cloumn, or anything else) in double-quotes when you create it, then you generally have to enclose it in double quotes and spell it exactly the same way (case-sensitive) every time you use it.
Lose the double-quotes:
create OR REPLACE type eleves_t as table of eleve_t;
create OR REPLACE type professeurs_t as table of professeur_t;
/All identifiers in Oracle are case-sensitive. You may not realize that because all unquoted code (that is, everything not in suingle-quotes, like 'foo', or double-quotes, like "bar") is converted to upper case before it is compiled.
So when you said
create type eleve_t ...the type that was created was ELEVE_T, all uppercase, exactly as it appears in all_objects.
When you referenced it like this:
create type "eleves_t" as table of eleve_t;there was no error, because all the unquoted code got capitalized before compiling, so it's as if you had said
CREATE TYPE "eleves_t" AS TABLE OF ELEVE_T;Because it was quoted, "eleves_t" was not capitalized.

Creating type along or inside a path

Hi All,
I read the tutorial about Creating type along or inside a path. I have tried to create few types of type along,inside and outside a path and shape. I was wondering why there are variations and restriction among them. Below are my screen shots to describe my problem.
Screen 1

Sorry, I have been trying to upload the screen shots, now it is done.
Screen 1: type outside the path
Screen 2:type inside the path
Screen 3:type outside the shape
Screen 4:type inside the shape
I am confused why I cannot flip the "type inside the path" whereas flipping inside and outside is possible for "type outside the path". Any help is greatly appreciated. Thank you.

Help using a created type

Anyone,
I started by creating a typelike this:
create type NUMS_TYP as object (nums number);
That seemed to work fine. Now I'm trying to use that type in a PL/SQL procedure like this:
FOR z IN (select empno from emp)
LOOP
IF z.empno IS OF (NUMS_TYP) THEN
htp.p ('NUMBER');
ELSE
htp.p('STRING');
END IF;
END LOOP;
I keep getting - PLS-00382: expression is of wrong type. Can anyone help?
Thanks,
Kirk

hi,
there is problem when you passing null plsql can't recognize type for null the workaround for it is just using explicit converstion
consider following
i use generic object - anydata in my OO api
CREATE OR REPLACE TYPE "IAS_ANYDATA"
as object
val_c varchar2(32000)
,val_n number
,val_d date
,old$val_c varchar2(32000)
,old$val_n number
,old$val_d date
,type varchar2(1)
,name varchar2(30)
,ind number
-- Attributes
-- Member functions and procedures
,CONSTRUCTOR function ias_anydata(val varchar2 default null) return self as result
,CONSTRUCTOR function ias_anydata(val number) return self as result
,CONSTRUCTOR function ias_anydata(val date) return self as result
,CONSTRUCTOR function ias_anydata(name varchar2, val varchar2, old$val varchar2) return self as result

,member function to_string return varchar2
,member procedure check_ind
,member function isNull return boolean
,member function isTrue(Bool_ind varchar2 default 'Y' ) return boolean
) not final
what will happen if i call following
z:=null;
o = ias_anydata( 'col1', z ); -- object of string becuse of default is null for varchar
o = ias_anydata( 'col1',to_date( z ) ); -- object of date
o = ias_anydata( 'col1',to_number( z ) ); -- object of number
