Callback function for addtocart()

Hi everyone,
I need to setup a callback function after addtocart(). Is there a way to do this?
Thanks.

Official one coming soon. You would have to override the addtoCart with your own currently (Standard overriding of javascript functions method)

Anonymous callback function for JSValue callWithArguments:

Hi, I'm trying to create an iOS7 app using JavaScriptCore, where the core of app is written in JS (which communicate with API). The problem is, I can't get to work anonymous callback functions. Is something like that even possible? Simplified example code below:
.js
function getArray(errorCallback, successCallback) {
     loading = api.getArray();
     result.waitOnSuccess(loading, function(list) {
          return successCallback(list);
    result.waitOnError(loading, function(error) {
          return errorCallback(error);
Obj-C
     JSValue *getArray = _context[@"getArray"];
     [getArray callWithArguments:@[^(id error) {
          NSLog(@"%@", error);
     }, ^(id success) {
          NSLog(@"%@", success);
I know I can do this, when I map native methods to JS context, but I would really like to do this anonymously. Thank in advance.

Callback Functions for the Enterprise API

I'm using VB to write some API functions to pull journal detail from Enterprise 6.0, but having trouble with the callbacks. I did find some syntax errors in the toolkit.bas file, correct those and am able to pull specific data points, but the enum functions just crash. Because the documentation is scetchy at best, I'm not sure if my functions are wrong, if there are other syntax errors in the .bas file or if the dll's are corrupt.<BR><BR>I'd really appreciate some help from someone who has experience writing callback functions to the Enterprise API.<BR><BR>Thanks in advance.

Hey there...
I think part (if not all) of your question can be answered by abstracting it a level. Think of all the tools that are available through PL/SQL or JAVA in the database. For instance...
* Heterogeneous Services that allow you to access any ODBC/JDBC data source directly from within the Oracle database.
* DBMS_JOB that allows the scheduling of jobs to run at a given time/interval.
* DMBS_FILE_UTL that allows Oracle to interact with the file system.
That doesn't even take into account the things you can do with Java in the database.
In short, just about everything you mentioned can be done in one shape or form with tools that reside in or around the oracle database.
HTMLDB is a front end interface tool that has access to all of the tools available to you at database level.
So in short (and in my opinion): Yes, it is capable of creating Enterprise level applications. I'm building a fairly complex one right now that interfaces with 2 external (non-oracle) databases via Heterogeneous services, and which used DBMS_JOB to schedule jobs to collate data from an external file system.
I hope this helps..

Callback function for network events

Hi all,
I'm working on a project, and I need to be able to respond to network events. I receive the data through a BufferedInputStream from a socket. What I want is a callback-type thing, i.e. When new data is sent to the socket, a function is called to receive that data. I've looked through the documentation, I can't find anything that could be used for that. The only thing I can think of is linking it to a JTextArea/JTextField, and attaching a change listener to that, but I'd prefer not to have to do that. My current method involves a loop, which I don't like at all:
while (true) {
if (server.Available()) {
do stuff here
I don't like it because it wastes processor cycles that really should go elsewhere. So what can I do?
-ReKleSS

When you read from a socket and there is no data available, it just blocks until something does become available. While the thread is blocked waiting for I/O it won't take up any processor time.

How to implement a callback function using LabView's Call Library Function Node?

I am trying to call a fuction from a SDK.dll library using the Call Library Function Node. The SDK was provided to
me and I do not have the source code, just the .dll and .h files.
The SdkSetPropertyEventHandler function has a callback fuction as one of its parameters. How do I implement the
callback using the CLF node? I am a good LabView programmer but this is my first time using the Call Library
Function Node. I have read all the info I can find on NI's web site and the discussion board but cannot figure
this one out. I am using LabView 8.6.
The SDK.h deacribes the function as:
// Function:   SdkSetPropertyEventHandler
SdkError SDKAPI SdkSetPropertyEventHandler(
            SdkCameraRef                    inCameraRef,
            SdkPropertyEvent                inEvnet,
            SdkPropertyEventHandler         inPropertyEventHandler,
            SdkVoid*                        inContext );
// Description:
//       Registers a callback function for receiving status
//          change notification events for property states on a camera.
// Parameters:
//       In:    inCameraRef - Designate the camera object.
//              inEvent - Designate one or all events to be supplemented.
//              inPropertyEventHandler - Designate the pointer to the callback
//                      function for receiving property-related camera events.
//              inContext - Designate application information to be passed by
//                      means of the callback function. Any data needed for
//                      your application can be passed.
//      Out:    None
// Returns:    Any of the sdk errors.
A separate header file called SDKTypes.h contains the following data:
typedef SdkUInt32 SdkPropertyEvent;
typedef SdkUInt32 SdkPropertyID;
typedef void       SdkVoid;
typedef struct __SdkObject*    SdkBaseRef;
typedef SdkBaseRef    SdkCameraRef;
SdkPropertyEventHandler
typedef SdkError ( SDKCALLBACK *SdkPropertyEventHandler )(
                    SdkPropertyEvent        inEvent,
                    SdkPropertyID           inPropertyID,
                    SdkUInt32               inParam,
                    SdkVoid *               inContext );
Thanks for your help.

Basically you do not do that. LabVIEW does not know pointers and certainly not function pointers. What you should do instead is writing a C DLL that implements the callback and also exports a function to be called by LabVIEW that translates between the callback and a LabVIEW user event. Look for PostLVUserEvent() here on the NI site to find examples how to do that.

Control array of callback functions?

Apologies for my basic question.
I am experimenting with control arrays and so far am able to collect data in string controls that are inside control arrays. Works well. Naturally, none of these controls need callback functions.
Now I have need of some momentary command buttons in a control array as well. So my question is, should I use a single callback function for all of the button controls in that single array? And if so, how do I go about identifying which element in the control array called the function? From reading on the forums, it seems as if use of the callback data parameter might get me there.
Just wanted to ask before I get off track. Thanks!
Solved!
Go to Solution.

Yes, callbackData can be of help in such a situation, but if you can limit to switch on array index to discriminate what to do your button callback could be something on this line:
int CVICALLBACK BtnAttayCallback (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
int handle, index;
switch (event) {
case EVENT_COMMIT:
handle = GetCtrlArrayFromResourceID (panel, control);
GetCtrlArrayIndex (handle, panel, control, &index);
switch (index) {
// Your code here
return 0;
(No CVI install here so I cannot test it: double check the code but it should reasonably work)
Proud to use LW/CVI from 3.1 on.

IPhone SDK: Breakpoints don't trigger in a Callback function

Hi -
I coded a callback function for a CFSocket object; I followed the steps outlined by the CFSocket reference page. Everything seems fine, and then I enable a breakpoint inside my callback function.
I run my code, and gdb does not stop into my callback.
There doesn't seem to be much infos online about this particular problem. Can anyone tell me what I'm doing wrong?
Thanks, Charles.

Have you used logging to verify that the callback is being entered?

How to use setTimeout for Callback function in ajax DWR?

Hi,
I am facing a problem of ajax request not returning back to the specified callback function. As a result my application screen gets locked waiting indefinitely.
The timeout in DWR is controlled using a setTimeout method.
Can someone plz tell me how to implement this in my javascript code so that my Callback function is invoked for sure.
below is my code snippet...
var dwrMap = new DWRMap(theMainForm);
     dwrMap['menuId'] = menuid;
CommonService.executeAutoLogOut(dwrMap, fnPerformLogOut);
else{
     fnDoAnalyze(analyzeUrl);
function fnPerformLogOut(response){
if(response == "timedOut"){
     alert("Timed Out");
     fnAskToLogin();
else{
     alert("Not timed out");
     fnDoAnalyze(analyzeUrl);
Here CommonService.executeAutoLogOut(dwrMap, fnPerformLogOut); is sending ajax request.
and fnPerformLogOut() is the callback function.

Declaring Callback Functions in CSXS Extension (for Flash)

A few features offered in Flash's scripting language are handful of event listeners you can attach to Flash that will in tern call any associated JSFL function you've attached to them while Flash is running. You can then listen for events like "documentNew", "documentChange", "mouseMove", etc.
JSFL Code Would Look Something Like this:
fl.addEventListener("documentOpened", myDocumentOpenedHandler);
function myDocumentOpenedHandler()
swfObject.call("callBackFunction_InsideFlashPanel");
My swfPanel registers a callback function, "callBackFunction_InsideFlashPanel" which would handle the event inside the panel.
This is a way of ensuring my Panel is notified when a change takes place in Flash.
Adobe has an article about it here:
http://help.adobe.com/en_US/Flash/10.0_ExtendingFlash/WS4B030CF7-0681-47e3-9E2C-9A6D799980 AA.html
My question is, how should this be implemented in a CS Extension using the CS SDK?
Thanks,
Clint G.

Right. The whole point of the question is if is possible to
dynamically declare functions for use as callbacks.
For example, in the standard loading functions, you register
a callback like this:
var load:Loader = new Loader();
var req:URLRequest = new URLRequest(swf);
load.contentLoaderInfo.addEventListener(Event.COMPLETE,
swfloadcallback);
load.load(req);
function swfloadcallback(e:Event):void
The problem with the standard callback function is that I
can't add additional arguments to it. For example, I couldn't have
swfloadcallback take in an additional argument (for example the
index of the swf I'm trying to load). What I'm wondering is if in
actionscript 3 it's possible to dynamically declare callbacks such
that I only have to write the code once, but in essence I am adding
additional parameters to the callback.
Hence the example I listed above. What I was trying to
accomplish there was basically dynamically creating callbacks that
understood which index to insert the loaded image into. But clearly
that example doesn't work.

How to create a callback function module

Hi all,
I am working in a requirement where we need to call a function module at a 'after change' event. So how to create a callback function module and register it with the crmvevent ?_
I created a sample function module and try to create entries in table crmv_event_cust, but i got an error message saying that the function module name I provided is not in table CRMC_FUNC_ASSIGN. When I try to create entry there, I got a message that function module is not in CRMC_OBJ_FUNC and that table is a standard table with no maintanance options !!
looks like i am going in wrong way ... can any one please help ??

Looking at my system all you need to do is create the entry for the callback function in maint view: CRMV_FUNC_ASSIGN.
Your entry should be as simple as Z-function name Object Function - <same as others in the segment you are assigning>
IE for the partner it would be CRM_PARTNER as object function, for general order processing CRM_ORDER
Take care,
Stephen

Calling a method from a callback function under ARC

Hi All
I previously wrote some HIDManager software. The HIDManager references were done in a Objective C class so within this object you have the code:
    IOHIDManagerRegisterDeviceMatchingCallback( k8055HIDManager, k8055BoardWasAdded, (__bridge void*)self );
Which registers with the HIDManager
The Callback function which is outside the class was as follows:
static void k8055BoardWasAdded(void* inContext, IOReturn inResult, void* inSender, IOHIDDeviceRef k8055HIDDevice)
    IOHIDDeviceOpen(k8055HIDDevice, kIOHIDOptionsTypeNone);
    CCVellemanK8055Driver * k8055 = (__bridge CCVellemanK8055Driver *)inContext;
    [k8055 setHardwareConnectionStatus : YES];
Any how my problem is in converting the code to ARC as under OS X 10.9 SDK and 64bit I'm now getting a EXC_BAD_ACCESS (Code=EXC_I386_GPFLT) at this line
    CCVellemanK8055Driver * k8055 = (__bridge CCVellemanK8055Driver *)inContext;
although removing the method
[k8055 setHardwareConnectionStatus : YES];
will alow it to build but then obviously the app won't work as required.
Could someone suggest a ARC safe way of accessing the passed instance so I can again call methods on it.
Cheers
Steve

Try using blocks instead. This is the callback I am using for libcurl.
static size_t callback(
void * contents, size_t size, size_t nmemb, void * context)
size_t (^block)(void *, size_t) =
    (__bridge size_t (^)(void *, size_t))context;
size_t result = block(contents, size * nmemb);
return result;

Queue with callback function not dequeuing

Hi,
I would like to ask you for help or for a hint regarding our problem with the queue:
A trigger is enqueuing to a queue. This works fine, but the callback function is never called. The queue already worked for a while, but since i changed something at the procedure called by the callback it does not work anymore.
I already have tried the following:
-Stopping and restarting
-Dropping and recreating (with the scheduler having no jobs anymore)
-Dropping, restarting the database and recreating
None of these worked. Where do I fail, when considering that the queue with the same scripts worked already? I post the script for creating the queue and adding the subscriber:
CREATE OR REPLACE TYPE pat_history_queue_payload_type AS OBJECT
( TSTAMP VARCHAR2(22 CHAR),
TYP VARCHAR2(10 CHAR),
DELTA_MENGE NUMBER,
ORIGIN VARCHAR2(1 CHAR),
TEXT VARCHAR2(1000 CHAR),
QL_TSTAMP VARCHAR2(22 CHAR)
BEGIN
DBMS_AQADM.CREATE_QUEUE_TABLE (
queue_table => 'pat_history_queue_table',
queue_payload_type => 'pat_history_queue_payload_type',
multiple_consumers => TRUE
END;
BEGIN
DBMS_AQADM.CREATE_QUEUE (
queue_name => 'pat_history_queue',
queue_table => 'pat_history_queue_table',
max_retries => 10
DBMS_AQADM.START_QUEUE (
queue_name => 'pat_history_queue'
END;
BEGIN
DBMS_AQADM.ADD_SUBSCRIBER (
queue_name => 'pat_history_queue',
subscriber => SYS.AQ$_AGENT(
'pat_history_queue_subscriber',
NULL,
NULL )
DBMS_AQ.REGISTER (
SYS.AQ$_REG_INFO_LIST(
SYS.AQ$_REG_INFO(
'pat_history_queue:pat_history_queue_subscriber',
DBMS_AQ.NAMESPACE_AQ,
'plsql://PAT.HISTORY_QUEUE_DISTRIBUTION.CALLBACK',
HEXTORAW('FF')
1
END;
The function CALLBACK which is called by the queue, is never called, I checked that with log messages. Also the package that contains the function is compiled ok.
Thanks.

MIDI in using DLL callback function

I am trying to get MIDI into LV. The dll used is winmm.dll and the function midiinopen (plus others) is described here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/_win32_midiinopen.asp
The main problem is I don't know how to program the Call Library Function Node properly in order to perform the call
plus set it to start receiving callback data, being midi messages. I have tried creating and registering a User Event and
passing the Event ref to the dll's "dwCallback" and then trapping the callback in an Event Structure, but nothing happens.
I have studied the "Communicating with a Windows MIDI Device in LabVIEW" example but it gives no hint since midi out
does not require the use of callbacks.
Please advice,
Stefan

Damn! Need to make this post shorter as this message
board just silently told me that it needs to be shorter than 5000 words
and ate up my lengthy repsonse with no way to get it back.
You can't configure a Call Library Node to pass a Callback function to
another function. Callback functions have been alien to LabVIEW for a
long time with good reasons and what it has now as callback function in
LabVIEw 7.1 and newer is not directly compatible with C callback
functions.
Basically as you want to get data from the callback function back into
LabVIEW there is really no way around some intermediate software layer
which in this case almost surely means your own specific wrapper DLL
written in C.
If you use LabVIEW 7.1 you could use user events but not in the way you
describe. Attached is an example of how you can use user events from
external code. Note the extra DLL you will have to write. You have to
watch out what data you pass back to the user event as it has to match
exactly the type you configured the user event for, otherwise LabVIEW
will simply crash on you.
For numerics this is quite simply and also shown in the example. For
strings you can't just pass back a C string pointer but you will have
to allocate a LabVIEW string handle with
handle = DSNewHandle(sizeof(int32) + <length of C string>)
and then copy the C string into it. For specifics about how to do this
you should refer to the External Code reference manual in your Online
Bookshelf. Similar rules apply for arrays or clusters for that matter.
If you want or need to do this for LabVIEW < 7.1 there are two
possible approaches but both are even less trivial. You could either
create a wrapper DLL that translates your callback events into LabVIEW
occurrences and for the data transfer back to LabVIEW you would have to
implement your own queing too, or you could use the Windows Message
Queue example somewhere here in the NI examples and adapt it to return
your specific data. That would solve the data queueing more or less for
you without having to worry about that.

JNI Multithreading/Callback Function Design Issues

Ok, I have been working on this for quite some time now and I simply can not figure it out. So any ideas are more than welcome. :)
I have Java code that uses a DLL that I created in C++. My C++ code links with a library made by a 3rd party (don't have access to the source or anything). The 3rd party's code creates a new thread and calls a callback function that I define in my C++ code. This callback is called continuously until I perform some other code to stop it. Now for the tricky part. In my callback function I need to pass some data back in Java. Here is where my design falls apart. Since the callback function is technically part of the 3rd party's thread, I have to call AttachCurrentThread() in the callback to get the JNIEnv pointer in order to ultimately call my desired Java method. The problem is that my Java method (or even the C++ callback function) are only invoked if I do a sleep() in my C++ code after I start the 3rd party code which creates the thread. If I do a Thread.sleep() in Java after I call the native function code, it just sleeps and the callbacks never get called. It appears as though the thread dies as soon as I return from my C++ code.
So now I am stuck. I have tried creating a thread in Java which simply calls the C++ code and the C++ code just loops waiting for an updated flag, however, this causes the 3rd party's thread creation code to fail (not quite sure why). However, even if their code worked, I'm not convinced this is even proper design. I apologize if this is simply a threading design principle as my multithreading programming techniques are a bit rusty and I've never done a multithreaded application this complex (this is a simplified version, but the idea is the same).
I welcome any suggestions or even documentation that may lead me in the right direction. Thanks in advance.

I have a similar issue.
from java I call a dll I wrote, which calls a third party scanner dll (cyber.dll). Everything works ok, except, when an event in the scanner occurs, it calls the call backin my dll, which calls the callback in java, which kills the vm with an access violation. If I execute the call back to java from a c method which I just called from java, it works, but if it gets called outside of the java execution of the native code, it fails.
I havent done anything with treads or syncronisation. Do I need to do this AttachCurrentThread stuff? If so, where do I get the _jvm handle as Im not starting the vm from c?

Callback functionality in Web dynpro

Dear Experts,

If you want to update with ajax a web dynpro application, you can not do this In CE 7.1 or earlier (I really don't know about 7.11). You can do this for example with a portal application, if it isn't something specific for the wd application you can move it outside and place it somewhere with your wd application, some playing with the pages will do this work.
You can do another thing: place a portal application, which will be invisible and will call some web service via ajax and use portal eventing to "inform" your we dynpro application. But in this case when you receive the event it will behave like the timer trigger, it will redraw you page.
