Compile error with action listener, ioexception
Hello, i have a (very basic) swing class which (basically) starts the whole program going as soon as you press a button.
Now somewhere down in the program, i have some file handling, so java makes you write 'throws IOException" all the way through your code.
Now i tried to do that in my swing class but i get the following compile error:
"BaseGui.java": Error #: 463 : method actionPerformed(java.awt.event.ActionEvent) in class BaseGui cannot implement method actionPerformed(java.awt.event.ActionEvent) in interface java.awt.event.ActionListener, implemented method does not throw java.io.IOException at line 31, column 15
I tried changing the "throws IOException" for some trying and catching, but to no avail. Any ideas what the problem could be?
never mind, i figured this one out.
Thanks anyway.

Custom button with action listener - will not invoke action listener
Hi
For whatever reason, I cannot find a concise example of a simple custom component that can invoke an action listener. The tutorials I've read so far either ignore this fundamental topic or only make the slightest make reference to it.
The best I have come up with - in terms of a simple prototype is below... but, the action listener is never invoked.... Can someone tell me what I am missing (full code below). Hopefully, what is missing or incorrect will be obvious to you JSF experts out there.
Thanks for any help!!

The changes were:
in "SpecialBtnRenderer"...
--new--
mb.invoke(context, new Object[1]);
--old--
mb.invoke(context, new Object[0]);
in "SpecialBtnTag"...
--new--
import javax.faces.event.ActionEvent;
--new--
MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding(specialBtnListener, new Class[]{ActionEvent.class});
--old--
MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding(specialBtnListener, null);
-Below is the entire application, again -- for those (like myself) who need concrete examples...
I hope this helps someone else! --f

Compilation errors with JDeveloper 10.1.2.2.0
Hello,
I want to change my environment work. First I worked with Eclipse (Europa, jre 1.6), I have no error with my following code source :
private List<String> lString;
and now I have a compilation error with the same code
' Error(43,14): <identifier> expected '
I think it's a compiler version problem but I'm not sure and I don't know how to change the compiler version.
If someone have any idea, I will be happy to receive response.
ThanksJDeveloper 10.1.2.2.0 doesn't support neither JDK 1.6 nor JDK 1.5.

"catch is unreachable" compiler error with java try/catch statement
I'm receiving a compiler error, "catch is unreachable", with the following code. I'm calling a method, SendMail(), which can throw two possible exceptions. I thought that the catch statements executed in order, and the first one that is caught will execute? Is their a change with J2SE 1.5 compiler? I don't want to use a generic Exception, because I want to handle the specific exceptions. Any suggestions how to fix? Thanks
try {
SendMail(....);
} catch (MessagingException e1) {
logger.fine(e1.toString());
} catch (AddressException e2) {
logger.fine(e2.toString());
public String SendMail(....) throws AddressException,
MessagingException {....I found the problem:
"A catch block handles exceptions that match its exception type (parameter) and exception types that are subclasses of its exception type (parameter). Only the first catch block that handles a particular exception type will execute, so the most specific exception type should come first. You may get a catch is unreachable syntax error if your catch blocks do not follow this order."
If I switch the order of the catch exceptions the compiler error goes away.
thanks -
Compiler bug in 10.1.3 EA1? get "Internal compilation error" with EnumSet
The code sample below generates "Error: Internal compilation error, terminated with a fatal exception" when doing make. It's a very simple example, it creates an EnumSet with one element and dumps it via the "toString()" method.
If I change the line:
"EnumSet set = EnumSet.of(Buttons.ONE);"
To:
"EnumSet set = EnumSet.allOf(c);"
It works fine. For some reason the "of" method of "EnumSet" crashes the compiler.
Any ideas?

thanks in advance for your helpBOOST cannot be compiled with WS6u2.
The oldest compiler that can build BOOST is Sun Studio 11 (C++ 5.8).
You will have better luck with Sun Studio 12 (C++ 5.9). Both Studio 11 and Studio 12 are free.
Get Sun Studio 12 here:
[http://developers.sun.com/sunstudio/]
Sun Studio 12 requires Solaris 9, 10, or Open Solaris.
If you are running Solaris 8, get Sun Studio 11 instead:
[http://developers.sun.com/sunstudio/products/previous/11/index.jsp]
After installing the appropriate version of Sun Studio, get all current patches for it here:
[http://developers.sun.com/sunstudio/downloads/patches/index.jsp]
Then check Simon's blog for advice on building BOOST with Sun Studio 11 or 12.

Compilation error with (amp) restriction specifier in C++ AMP
Hi,
[double post from :
original post ]
I'm using C++ AMP (I'm not that experienced with C++ and I'm new to AMP, so I have to stumble through this stuff) But I thought I had this code working, but now I'm getting the following error:
Error 1 error C3930: 'WRC_Raytracer::RaytracerRTC::RenderSceneWithAMP::<lambda_c13eb21eb34534d03d408733745bcf16>::operator ()' : no overloaded function has restriction specifiers that are compatible with the ambient
context 'Concurrency::_Parallel_for_impl'
Here is my parallel loop (cut down slightly to focus on the issue):
[code]
parallel_for(0, 720 * 576, 1, [w, cBuffer, pixelDataView](int i) restrict(amp)
// compute x and y for the given index
float x = (float)(i % w);
float y = (float)(i / w);
// convert color from {0,1}f to {0,255}b
int bInt, gInt, rInt;
bInt = (int) (min(x/719.f, 1) * 255);
gInt = (int) (min(y/575.f, 1) * 255);
rInt = (int) (min(0, 1) * 255);
// represent color data as (int)argb
int pixelAsInt = (255 << 24) + (rInt << 16) + (gInt << 8) + bInt;
// update pixelData element
pixelDataView[i] = pixelAsInt;
[/code]
Can anyone see what's wrong here ? As I said, I'm sure this was working yesterday, and I did something just before shutting down, and now it's not working.
Edit : I tried the parallel_for_each loop that I had started with. And that actually does work ...
parallel_for_each(pixelDataView.extent,[=](index<1> idx) restrict(amp)Hello Gavin, thank you for your question.
Note that parallel_for_each (more precisely, the overloads that accept extent arguments and take a restrict(amp) functional parameter) is the unique entry-point for C++ AMP execution. Other functions in the concurrency namespace, such as parallel_for,
are unrelated, and stem from a different technology (PPL). Since restrict(amp) is specific to C++ AMP, trying to use a restrict(amp) functional object in any context but that of C++ AMP execution, is not possible - hence the compiler error
you were seeing. Hopefully this turns out helpful for you. Also, congratulations for picking up C++ AMP, I hope you like it! Cheers! -

Form the error message it seems like a bug in cg.
Try the follwoing option and see if the bug goes away.
-Qoption cg -O0 or use -Qms_pipe-off.
Please refer C user's guide for usage.

Compiler Error with simple vi using MatLab script nodes
While attempting to build a simple vi to test the capabilities of LabView's interface with MatLab, I received a compiler error message that said I should report the problem to National Instruments Tech Support. The error said, "reference to undefined label from: refPC=0x41C." I've attached the vi that created the error. I am using LabView 7.0 on a PC running Windows 98.
Attachments:
Compliererror.vi 11 KBI don't know if this will help your problem, but there is a fix for some problems with LabVIEW 7.0 and Matlab:

BUG: 10.1.3..36.73 Internal Compile Error with enhanced for loop/generics
I get the following compiler error when using the Java 5 SE enhanced for loop with a generic collection.
Code:
public static void main(String[] args)
List<Integer> l = new ArrayList<Integer>();
l.add(new Integer(1));
printCollection(l);
private static void printCollection(Collection<?> c)
for (Object e : c)
System.out.println(e);
Error on attempting to build:

Compilation error with dataProvider attribute
My objective is to have a ComboBox itemEditor for a column in
a DataGrid. This
will get used in a number of places in our app, for example
to add an order
line to an order. We would want the ComboBox to be populated
with the list of
available products, and Flex goes most of the way to
providing that
functionality. But I get a compilation error on a line that I
would expect to
work. Here's the full sample:
quote:
<?xml version="1.0"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
height="700" width="700"
creationComplete="onLoad()">
<mx:Script>
<![CDATA[
[Bindable]
public var myDP:Array = [
{label1:"P1", quantity:3},
{label1:"P2", quantity:3}
[Bindable]
public var products:Array = [ {label:"P1", data:1},
{label:"P2", data:2}, {label:"P3", data:3} ];
public function onLoad():void
ProductsRequest.send() ;
]]>
</mx:Script>
<mx:HTTPService id="ProductsRequest"
url="
http://localhost:3000/lists/productlist"
useProxy="false"/>
<mx:Component id="ProductCodeEditor">
<mx:ComboBox
dataProvider="{ProductsRequest.lastResult.products.product}"
labelField="name"/>
</mx:Component>
<mx:ComboBox
dataProvider="{ProductsRequest.lastResult.products.product}"
labelField="name"></mx:ComboBox>
<mx:DataGrid id="myDG" dataProvider="{myDP}"
variableRowHeight="true"
editable="true">
<mx:columns>
<mx:DataGridColumn dataField="label1" headerText="Product
Code" itemEditor="{ProductCodeEditor}"/>
<mx:DataGridColumn dataField="quantity"
headerText="Quantity"
editorDataField="value">
<mx:itemEditor>
<mx:Component>
<mx:NumericStepper stepSize="1" maximum="50"/>
</mx:Component>
</mx:itemEditor>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
</mx:Application>
I get a complation error on the following line
quote:
<mx:Component id="ProductCodeEditor">
-->> <mx:ComboBox
dataProvider="{ProductsRequest.lastResult.products.product}"
labelField="name"/>
</mx:Component>
The error message is "Access of undefined property
ProductsRequest"
However, the other <mx:ComboBox> definition compiles
and works fine. In
other words, in the sample code (shown again below) we have
two <mx:ComboBox>
definitions with the same dataProvider definition. The one on
line 33 compiles
and works, the other doesn't, and the only difference is that
one of them is
within a <mx:Component> declaration.
quote:
27 <mx:HTTPService id="ProductsRequest"
url="
http://localhost:3000/lists/productlist"
useProxy="false"/>
28
29 <mx:Component id="ProductCodeEditor">
30 <mx:ComboBox
dataProvider="{ProductsRequest.lastResult.products.product}"
labelField="name"/>
31 </mx:Component>
32
33 <mx:ComboBox
dataProvider="{ProductsRequest.lastResult.products.product}"
labelField="name"></mx:ComboBox>
I really can't believe that this behaviour is by design. If
it is, could
somebody tell me what this design is, and how I am supposed
to populate a
combobox with product codes in a grid?
Thanks,
Ed.Sorry, I see you are trying to do that. I am not yet familiar
with inline renderers.
However, I suspect a scope issue. I bet the renderer
component does not have access to the application scope, where the
dataService is declared.

alarmClock->onAlarm(passAheadRef, alarmId);
return;
Any help is highly appreciated. Thanks.

[email protected]The C++ Migration Guide that comes with the compiler explains in detail everything you to need to know about migrating from C++ 4.2 to C++ 5.3.
Use the "-compat" option on every CC command, compiling and linking. Any code that worked with C++ 4.2 will work the same way with C++ 5.3 in compat mode.
-compat=4 sets language and binary compatibility to that of the 4.x compilers. -compat=5 sets language and binary compatibility to ANSI/ISO standard mode. If the -compat option is not specified, -compat=5 is assumed.
