What class is Record in?
Anyone out there know what class a Record object is in? What do I need to import to use it? Thanks.
Umm... a Record object is an instance of the Record class, of course. If you're wondering what package the Record class is in, I didn't see any mention of a Record class in the standard API for JDK 1.4 or for JDBC. Perhaps your instructor created the class, in which case you'll have to ask him/her.

What class should I extend for this custom control?
The code below is my attempt at a mxml control to replace a custom context-menu that my app needs on certain textInput controls. Characters not on the keyboard are inserted into the text, replacing any selection, if applicable. Flex AIR apps (which I need for local access to SQLite) don't let me do custom contextmenus when the control is not top-level.
The custom component is encapsulated now in a Panel but I would like to have the composite control be nothing more than a textInput and a PopUpMenuButton right next to it. Is that possible—not to have a container? If so, what class should I extend, if creating this as an ActionScript component?
Thanks for the advice.

Here is the simpler approach where HBox encapsulates the TextInput and PopUpMenuButton. I am trying to figure out how to let the TextInput keep its selection highlight when it loses focus to the PopupMenuButton: setSelection does not cause the repaint.

I Am trying to view on my iPhone what I am recording on my canon VIXIA x. How do I do this
I sounds like that is not a feature of the uploader all.
Built-In Wi-Fi. The mini X's built-in Wi-Fi allows you to easily share MP4 video recordings and still images over the Internet via social networking sites such as YouTube and Facebook using the Canon iMAGE GATEWAY# online photo storage service. You can also transfer files to a home or office PC. Uploads can be made virtually anywhere using an iOS mobile device and the free Canon Movie Uploader app. HD video can also be shared via Wi-Fi using compatible home or office wireless networks, wireless hotspots and iOS-compatible mobile phones and tablets using the Movie Uploader app.

How do you know what classes to use ?
Hello,
This may sound daft - but how do you know what classes to use to do a particular task ? For example to do password-related stuff - how would I know which classes are all relevant to that ? Am I supposed to buy a book on the classes as the API documentation doesn't really tell you WHEN to use which classes.If you're using JSP, then your password field is likely going to be implemented in HTML. So that's nothing to do with Java. (And you can't use a JPassword field in a JSP page.) But when that field comes back to your server, you may be using Java to authenticate it. Even there, the question is not yet what Java method you are going to use, but what methodology. You could have a database to authenticate against, or an LDAP directory. Or you could have the web server use its built-in authentication, which means you don't have to do any Java coding at all. And there are other ways.
So the question before yours is, how do you know what methodology to use? Again, that comes down to experience. -
What classes do I need to make this "if" statement?
what classes do I use or how do write code that basically says:
if ( the key typed was not enter) {
I couldn't figure it out using the keylistener.
Thanks in advance.Use a KeyListener like this:
JTextField textField = new JTextField();
textField.addKeyListener(new KeyListener() {
@Override
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_ENTER)
System.out.println("Enter pressed");
@Override
public void keyReleased(KeyEvent e) {
@Override
public void keyTyped(KeyEvent e) {
});in keyPressed() and keyReleased() you can check for e.getKeyCode() == KeyEvent.VK_ENTER
in keyTyped() you should check for e.getKeyChar() == '\n' -
What is Condition records in tcode NACR?
Hi all,
I started with NACE and went to NACR somehow... Please explain in layman terms what is condition records and is it related to EDI/IDocs? Also and if possible point me to related files or threads.
Thanks,
Charles.Hi,
Condition records are used for proposing the output type. If there is no condition record then the output type will not be proposed..
Let's say you want to propose a new output type only for a particular customer..
The following steps are required..
Create a new condition table with customer as the key fields..
Create an access sequence and then assign that condition table..
Create a new output type in NACE..And assign the assign sequence..
Assign the output type to an ouput determination procedure..
Use the transaction <b>NACR</b> to create condition record for that particular customer..
Now..The output type will be proposed only for that customer..For the other customers..the output type will not be proposed..
Check this link for condition technique for more details..

What classes should I use to send/receive bytes inmediately?
What classes should I use to send/receive bytes inmediately? I mean, without using any buffers or whatever (I will implement this on my app), just the faster method.
Is InputStream/OutputStream the lowest level choice?
Thanks!Hi!
Thank you very much for your help, I appreciate it a lot.
While I test my server, I execute ping www.myclienthost.com -t (my client games are in other office, in the same building, but different ISP) and I don't see anything strange, so I guess network is working perfectly. However, if I use wireshark (sniffer) and I see that my system fails (server does not send acks so client disconnects) is because my acks messages are not sended for 6 o 7 seconds (it should send them every 2 or 3). It seems thread is blocked. and after 6 or 7 seconds one message with 2 or 3 acks together is sent. So, I see that the thread handler blocked for a few seconds and this is doing my server is failing. Why client handler thread on my server is blocked? One question: every 2 or 3 seconds I have a thread that uses sleep that iterates thru client handlers and takes OutputStream and send one ack message for every client handler. My question is, in client handler class I have a method called SendInfo(String whatever) which encrypts and sends through OutputStream, should I protectd this method from accesing from two threads??? as acks thread and client thread can access at the same time. Could this be the problem??
EDIT: In my previous post I forgot to say what I found out with wireshark. Here I explain it. Sorry.
By the way, how can I debug threads?? I would like to know if my client thread is blocked in that critical moment.
Thanks a lot for your ideas and sorry for my English.

What are future records in OM ?

Any body any idea what are future records in OM?

sasHi,
I have not heard of any term called future record. But may be if some objects or relationship whose validity starts in future are called future records. To see those records in PPOSE click on "date and preview period" and give the date in future when the relationship exists, it will show up that in the structure.

What class needs to be imported when you use loadVars?
Does anyone know what class you need to import to get this
working?
var my_lv:LoadVars = new LoadVars();
my_lv.onData = function(src:String) {
if (src == undefined) {
trace("Error loading content.");
return;
content_ta.text = src;
my_lv.load("content.txt", my_lv, "GET");Thanks, i noticed it.
But now i wrote a class for it, but why can't i run a
function after the text is loaded?
It seems it never run's the function doSomething.
Am i doing Something wrong? -

DanAfter the 900 annoucement at CES, I had sent e-mails to both Stephen Elop from Nokia, and Steve Ballmer at Microsoft. I got responses, but can't be to sure if it was actually them that responded personally. With Stephen, we shared two different emails on Verizon/CDMA Windows Phone devices:
Stephen Email 1
Sorry, we can't share all future product plans with you, but it is our intent to serve the widest variety of customers in the US as we move forward.

Stephen
Stephen Email 2
Hello there,
Just for clarity, we announced in October that we will be supporting CDMA in 2012, although we have not made specific announcements about with which operators and when, so there is no issue with CDMA support. And for a variety of competitive reasons, neither ourselves nor operators want to announce some of what you would like to see announced until we are closer to actual dates.
Thanks for the continued interest.
Regards,
Stephen
Ballmer Email - now, this wasn't an email questioning Verizon, it was me questioning if Microsoft and it's partners just plan on neglecting CDMA customers with WP7. His response was short and sweet, which makes me think it was him personally.
We also love cdma and will push the partners

To what class does this method belong?
If one sees in the documentation something like
- (retType *) text1:(Type1 *)aType1 text2:(Type2 *)aType2;
then to what class does this method belong? I do not see in the Objective-C documentation any way that one can tell without the 'context' in which the method is declared or defined. This makes reading the documentation very difficult (for me). What you see is not what you get. There is stuff missing.
In my world there is no difficulty in determining the class to which a method belongs. It is stated explicitly in the method name. For example:
PROCEDURE (self: MyClass) methodName (arg1: Type1; arg2: Type2);
and one sees that 'methodName' belongs to 'MyClass'.
In Objective-C how does one know the class to which a method belongs? Is it only determined by context, that is, by the fact that it is within the @implementation section or that it is within the @interface section? If that is the case then I would think that in documentation one should always be required to assert something like:
<<MyClass>> -(retType *) text1:(Type1 *)aType1 ...
-Doug DanforthPeeJay2,
I think I now have the distinctions needed but still have a question about what you said. But first here is my current understanding. A "method" is by definition bound to *at least* one class whereas a "message" need not be bound to any class. Hence one can send any message to any class and it will either be handled or ignored. A message looks like a method signature (and maybe one but is not constrained to be one).
The difference between C++ and Objective-C is that in C++ method calls are not messages sent to a receiver. They are just calls of the method for the dynamically bound object. That method must be syntactically correct at compile time whereas messages need not be syntactically correct for any receiver. At least that is my current understanding.
Now my question. You state that "casting the receiver of a message will in no way alter the flow of the code". I attempted to test this with a simple program but ran into a problem (see my new posting "Multiple classes in one file?").
Assume the following
@class Child : Parent
Child *child = [[Child alloc] init];
Parent *parent = [[Parent alloc] init];
Parent *bar;
bar = child;
[bar doSomething]; // (C) call to child's doSomething method?
[(Parent *)bar doSomething]; // (P) call to parent's doSomething method?
You comment seems to say that both case (C) and (P) give the same result. If they do then which result is it the parent's or the child's method (assuming that the child has indeed reimplemented the parent's method)? Have I understood you correctly?

What Class/Method/Object's would I use to send variable form data to BradySoft? I have a basic label setup in BradySoft and I want to send it variable form data (a serial number) from Labview ActiveX. I have attached Brady's ActiveX programmers guide but can't figure out what to use for this. P.S. I would call Brady or TekLynx tech support about this but they have a strict policy whereas BradySoft supports ActiveX but their tech support doesn't provide programming help with it. I figured I'd try the NI Forums.
Aaronb, I presume by publishing an ActiveX programmers manual the BradySoft software installs Active X objects. You may choose to interact with these objects within LabVIEW using Active X controls. The following link will provide a starting point for LabVIEW help topics on Active X communication: Select ActiveX Object Dialog Box
