New to Logic, trying to figure out drag and drop kits
Hey guys, I just bumped up from GB to logic and I need some advice on how to get some good sounds out of it besides the stock ones. I'm trying to make my own drum kit with the drag and drop version but I'm not really sure how it works. Any advice on this or other tips would be greatly appreciated
Thanks,
Alex
btw, I'm trying to make some synth samples with logic for my band. We play hard rock with synth... Just to give you an idea haha
Hi,
There is an example here that leads you through the steps to building dynamic tables: http://assure.ly/gk8Q7a.
If you are using the table object, then you do not need to wrap this in a subform. If you select the row in the hierarchy, you can go to the Object > Binding palette and set it to Repeatable.
The other issue is to make sure that the form is saved as a Dynamic XML Form in the save-as dialog.
Hope that helps,
Niall

Trying to figure out pricing and plan options to add multiple computers to current subscirption. We currently have a subscription that allows the programs on two computers, but now I need 5 computers to be updated with CC. Have looked in to Small Business teams, but do not understand how many computers that is good for and if there is a professor or previous customer discount. Any help would be great, thanks!
Hi,
I presume that the new configuration is missing some parts as you seem to have the IP address of the external interface configured staticly on the interface but you have not configured any default route on the firewall? (Original configuration got default route dynamically and added it to the routing table)
You also mentioned that you were able to connect to the Internet which would indicate there was indeed a default route with the new configuration?
I am a bit confused about the host mask on the external interface (/32 - 255.255.255.255) ? Does the ASA really let you configure a host address on the interface? It can't lead anywhere as there is no next hop with a host mask. I think the ASA even blocks using a /31 mask link network which works with Cisco Routers.
I guess I would go through the basic troubleshooting step when the new configuration is in use
Check logs for any blocked connections or error messages
Check the Static PAT (Port Forward) configuration with the "packet-tracer" command
Capture traffic on the ASAs external interface (with the ASA itself) and confirm that you are seeing the TCP SYN of any connection attempts, or perhaps capture ICMP

With the new Photos app, I can no longer drag and drop photos into other applications as I did with iPhoto. For instance, I have a photo collage app that in the past, I could just drag in the photos I wanted to include. Now, I can DRAG the photos, but they do not DROP. So, I have to go through the export process. It is tedious. What am I missing? Where can I turn on the drag and drop feature for Photos?
YOu're not looking in the right palce. That's inside the iPhoto Application.
You need to look inside the iPhoto Library
As I sid above:
Go to your Pictures Folder and find the iPhoto Library there

Trying to figure out cause of dropped connections...
Hello, I have an Airport Extreme (a few years old) working with a MacBook Pro.
I'm trying to figure out the cause of occasionally dropped connections. One interesting thing I noticed today was this: the wireless indicator on my MacBook pro (in the status bar) was off. Then, when I restarted the machine, it connected to my base station automatically.
Does this mean that the base station has been fine all along and that maybe the card is flaky?
The other piece of evidence I have is a MacBook running side by side with the MacBook pro, and once I saw the MBP connection drop while the MacBook's stayed intact.
But the base station itself is a few years old and of course wi-fi is always subject to interference (especially in high rise apartment buildings). I recently changed the channel from 1 to 4 and seem to have had better success.
My MBP connection has been fine using other hot spots (e.g. Starbucks).
Is it worth trying to replace the base station and seeing what happens?

Hi, I'm surprised I can't quickly find if anyone else is having this issue. For me it has been going on since Lion on my 13" MacBook Pro 2011 and it's still persisting in Mavericks, and even still now that I've "downgraded" to a 15" MacBook Pro 2010 with Mavericks. The behavior is odd and difficult to explain concisely. Basically, when I want to add an attachment to Mail, I'll Cmd+Tab over to Finder click and drag and Cmd+Tab back to Mail, and drop the attachment. At first it looks fine, but when I click in the New Message window where I just dropped the attachment, to move the cursor, it retreats to the background and the Mail Main Window comes to the foreground. Then, if I click on that, the Finder window that I just used comes to the foreground. Sometimes if I switched to another app before going to Finder to select the drag and drop, that other app window will appear in the foreground instead. If I click on the other app window that is now in the foreground, then the Finder window that was last used will come to the foreground. The only thing that seems to fix this switch-a-roo effect is Cmd+Tab-ing back and forth a few times, or click on the window "frame" at the top to move the window around.
The way to prevent this is to have my Mail Message window visible in the foreground side by side with the Finder window when the drag and drop occurs (this is a tedious extra step if mulitple windows are open, or to use the add attachment command in the menu within Mail. But it sure is annoying buggy behavior.
Thanks
DanielYep, I get exactly the same thing when using Thunderbird mail client on my 2011 iMac running Lion. I've been putting up with it for at least a year, maybe longer.
For me it appeared to start after a Thunderbird update, so I figured that was the cause and couldn't find a solution at the time. However I've now noticed it starting to happen in Apple Motion 4 when dragging files from Finder into a DropZone in my animations. Motion remains the active program but the Finder window sits on top until I Cmd-tab out to a third open program (ie not Finder) and back to Motion again.
This is the first indicator I've had that it's an OS X issue.
Be great to find a solution as D&D is by far my preferred way of adding attachments to emails and similar tasks. -
Got the new Itunes update..how do I drag and drop a song onto my phone now?
Reluctantly, I updated my Itunes to the latest version. Glad they could make it a thousand times more confusing. If that was their goal...mission accomplished. I simply want to drag and drop a song that I purchased on my home computer to my ipod or iphone. In the good old days before the latest "improvement", you could simply drag the song to your device. Now, I can view my device. I can view the song. I cannot add the song to my ipod or iphone. Itunes helps actually offers no help for this basic operation. I've asked a few other pc people that have iphones/ipods and they say they just buy the song on their device because they cannot figure it out either. Was this really progress? Bravo on the update, apple guys. You made it so cool, now nobody but you fools can use it...
I got my own answer !! I saw it on another post. Select "View" and then toggle down to "View Sidebar".
Now I can drag and drop like before. -

Thanksif you can't explain, you can't get specific help. you can still use google to search for tutorials and you may get enough help to see you past the problem(s) you're having.

Who'd like to test a new Drag and Drop Interactive Widget?
It's taken about 6 months of every spare minute we could find but we're finally ready to do a round of Alpha testing for our new Drag and Drop Interactive Widget for Cp4 and 5. This post is to ask for a handful of volunteers to test the new widget over the next week creating drag and drop interactions in both Cp4 and Cp5.
If you've already tried our well-known Drag and Drop Lite Question Widget, but were a bit frustrated by the limitations that the quiz question format placed on your creativity, we think you'll be blown away by what this new Interactive Widget can do. It does everything the current question widget does, aside from the aspects that are unique to question types (Review Area, Retake Quiz, etc) plus a whole lot more. Due to the extra functionality, this widget has twice as much code as our last one.
Some of the features:
You can have as many widgets as you want on a single slide and each can be addressing a different drag and drop scenario.
You can reference the same drag and target objects from different widgets to create different.
Since they are interactive widgets, you can use the widget success/failure criteria to trigger Advanced Actions. This opens up a lot of possibilities for game interactions.
You can score each widget differently so that OnSuccess they will each report different scores for dragging the same objects. This means you can have Conditional Scoring and more than one correct answer for a given problem.
You can set one of the widgets to have its Preferences be used for all widgets on the slide so that you don't need to set all widget preferences individually, thus saving a lot of time.
You can set Preference Priority for each widget to configure which widgets will have "right of way" if there is a potential conflict in preferences. For example, if one widget wants one type of snapping behaviour on an object but another widget wants the same object to snap differently, the widget with the higher Preference Priority will dominate.
You can nominate other interactive objects (including clickboxes or other widgets) to act as Submit button and Clear button to create a simulated quiz question.
Since this widget is an Interactive widget, it also has the same advanced Pausing override behaviours we built into our Event Handler widget (http://www.infosemantics.com.au/eventhandler) So you can have users stay on the same slide playing with the drag and drop interaction for as long as they like without progressing to the next slide until they want to.
Plus other stuff I can't think of right now.
If you decide to volunteer to participate in this Alpha testing, please don't use this widget for any production Captivate projects you may have. The Alpha and Beta versions of the widget will be time-bombed to stop working after a couple of weeks so that we don't have buggy versions running around later.
As I said at the beginning, we only need a handful of testers, we need people using either Cp4 or Cp5, and you need to do this testing over the next week so that we can then address any issues you find and release a debugged Beta version for more testing.
Anyone wanna play?
If you do want to volunteer, send me a private message on this forum with your email address so I can send you a widget and instructions. We'll only be taking the first dozen or so people that are willing to contribute time and feedback.
Cheers,
Rod WardHi Sandy,

The drag and drop functionality is grayed out in Captivate 8. How do I turn this on?
I'm trying to play with drag and drop functionality in Captivate 8, but it's grayed out. All the tutorials I've watched show it working, but in my project, I can't access it. Any ideas?
I asked about this in another thread, to add a list of what is NOT supported in responsive projects to the documentation:
objects detected by the HTML5 tracker
Drag&Drop as you discovered
line shape
free polygon shape
This is my list. Answer in another thread from the staff was: what is dimmed, grayed out is not available. Not a pleasant way to discover limitations, although I understand not everything could be implemented in this very first version of Captivate responsive design functionality.

Newby to Flash -- need help with Drag and Drop
I have been trying to create a drag and drop in Flash where I have five different places for an instance of a mc to be dropped. I want to be able to drop only three instances to each place and these three instances are specific to one of the five "drop places". I also want the mc instance to go back to its original position if it is not dropped on the right place. I've got the actionscript working to drag and drop the mc instances on the "drop places" but I cannot figure out how to do the if statements so that if it doesn't match the correct drop place it will go back to its original position.
Here's some of my code:
Analyze1_mc.objName = "Analyze1";
Analyze1_mc.val = 1;
Design1_mc.objName = "Design1";
Design1_mc.val = 4;
Analyze1_mc.buttonMode = true; // sets mouse pointer to hand
Design1_mc.buttonMode = true;
Analyze1_mc.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
Analyze1_mc.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
Design1_mc.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
Design1_mc.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
var originalPosition:Point;
function returnToOriginalPosition(): void
originalPosition = new Point(x,y)
x = originalPosition.x;
y = originalPosition.y;
// function to drag item clicked
function fl_ClickToDrag(event:MouseEvent):void
event.currentTarget.startDrag();
event.target.parent.addChild(event.target);
function fl_ReleaseToDrop(event:MouseEvent):void
var target:MovieClip = event.currentTarget as MovieClip;
var item:MovieClip = MovieClip(event.target);
item.stopDrag();
if (event.target.hitTestObject(AnalyzeTarget_mc) && (event.target.val == 1)) {
trace ("Analyze1");
event.target.x = AnalyzeTarget_mc.x + 42;
event.target.y = AnalyzeTarget_mc.y + 5;
updateItem(Analyze1_mc);
} else {
returnToOriginalPosition();
if (event.target.hitTestObject(DesignTarget_mc) && (event.target.val == 4)) {
trace ("Design1");
event.target.x = DesignTarget_mc.x + 42;
event.target.y = DesignTarget_mc.y + 5;
updateItem(Design1_mc);
} else {
returnToOriginalPosition();
function updateItem(item:MovieClip):void {
buttonMode = false;
removeEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
I put the trace in to check the function -- and I do get the output when the mc instance is dropped on the right place -- but there is no return to original position if the instance is dropped in the wrong spot and there is no update to the mc instance.
Any help would be greatly appreciated. Thanks!That line you speak of is merely declaring a variable, nothing is being assigned to it.
One way of assigning the original position data to each object is to just assign it like follows:
Analyze1_mc.originalX = Analyze1_mc.x;
Analyze1_mc.originalY = Analyze1_mc.y;
etc...
Another way to do it with less code is to assign it generically just before you start dragging each of them...
function fl_ClickToDrag(event:MouseEvent):void
event.currentTarget.originalX = event.currentTarget.x;
event.currentTarget.originalY = event.currentTarget.y;
event.currentTarget.startDrag();
event.target.parent.addChild(event.target);
One thing I noticed in your code earlier is that you switch between using event.currentTarget and event.target. If you want to be sure that the object your code is targetiing is the object that has the listener assigned to it (your movieclips) stick with using currentTarget. target can end up pointing to something inside that object instead of the object itself. In the following lines...
var target:MovieClip = event.currentTarget as MovieClip;
var item:MovieClip = MovieClip(event.target);
You could very well be assigning target and item as being the same object. I don't think that is what you want. You might wanting to have one of them be the object you drop it on, which would be the dropTarget, not the target -
OK - Here's my problem. Just moving from AS2 to AS3 and
trying to create a drag and drop template. I need to re-use a
single drag selection multiple times, to multiple targets and then
graded. For example, say I was building a car by dragging parts
over to a car frame. I need to be able to drag a copy of a tire to
the car frame 4 times in any random order. Drag 2 doors in any
order, or drag one item like a hood... etc, then grade to make sure
all are in the right place.
I have succedded in dragging a specific Drag item to a
specific Target and give feedback as it is dropped (either "wrong",
"correct" or "Good Job, Completed"), but having a bear of a time
trying to figure out how to use one Drag item for multiple Targets.
Anybody have a sample template FLA of the same concept that I
can build from?
Many, Many, Thanks!What I am trying to do is to be able to use one of each of
the images on the left multiple times, and put them in the correct
position on the diagram in any order and then checked after student
drops the item on a target. (sample sent to email)
I have 1 for 1 working (working targets have green
highlight), but can’t figure out how for instance, drag 2
barrels in any order, 6 red squares over in any order and 2 orange
circles over in any random order. I am stuck on 1 drag item for one
specific target only.
I would like the selections to remain to the left and copies
of them created and dragged to the targets. (currently they are
removed from the left when dragged) -
Advanced Feedback with Drag and Drop Interaction
Hello,
I am trying to create a drag and drop interaction that will blend in a "thumbs up" or a "smiley" after each dragable has been correctly placed. The dragables in my interaction are medical terms and the drop sources are smart shape boxes. Each drop source has been assigned one correct answer, so that when the correct answer has been dragged a "success caption" appears immediately. The opposite occurs with an incorrecty dragged term. I figured, I need a "code" that
askes each dropable if it is the last one to be answered, and when answered correctly, will show the "smiley"
checks if all other dragables have been placed correctly
Since I lack the basic coding knowledge, I am having a hard time trying to figure this one out. Thanks for the help, again!
-NikHi Jay,
Yes, could create such a scenario, but the Submit button is not used in that case, because the feedback will appear immediately when a drag object has been placed on the target. Is that OK?
Here the work flow:
Besides the object, create all the feedback text containers that you need, correct and incorrect and label them so that they are easily recognizable. I labeled them FB_1, FB_2... because my objects were Drop1, Drop2...
Make those feedbacks initially invisible and group them in Gr_FB
Create the drag&drop in the normal way with one correct link
Select the target and in the in the D&D panel, click on the Accept button, change the settings like this
The advanced actions are pretty simple, standard, with two statements: Hide Gr_FB and Show FB_n (with the appropriate feedback container - you cannot use Shared actions in this dialog).
In the D&D panel, choose Infinite for the number of attempts and uncheck the Failure caption.

hi
ive got the following code. bevvy is a movieclip, theres a dynamic text box called feedText nd a box..imaginately called box.
I'm trying to create a drag and drop game when the user drags a word into the box that will have its meaning beside it in a text box, the dynamic text box will tell them if they are right or not. if they are right the word stays, if not the word will go back to its original location. the dynamic text box will give feedback whether they are right or not.
the code below means that the word will stay in the box, but the text message is displayed all the time. i also have a reset button to make the word return to its origal location but id rather not have the button.
any thoughts please?
bevvy.addEventListener(MouseEvent.MOUSE_DOWN, mouseDown)
var onTheRun:Boolean = true;
function mouseDown(event:MouseEvent):void {
bevvy.startDrag();
bevvy.addEventListener(MouseEvent.MOUSE_UP,mouseUp)
function mouseUp(event:MouseEvent):void {
bevvy.stopDrag();
resetButton.addEventListener(MouseEvent.CLICK, reset);
function reset(evt:MouseEvent):void {
bevvy.x=99
bevvy.y=131
addEventListener(Event.ENTER_FRAME,enterFrameHandler);
function enterFrameHandler(event:Event):void{
if(bevvy.hitTestObject(box)&& onTheRun){
onTheRun = false;
bevvy.stopDrag();
bevvy.x=box.x;
bevvy.y=box.y;
feedText.text="well done thats right"thanks so much!
put the code in and it works.
now for my next problem, i want to add another word into the game. so put the same code in, changed it according to instance names etc and get this error:
1021: Duplicate function definition.
its because i have two mouse up and two mouse down functions like this
bevvy.addEventListener(MouseEvent.MOUSE_UP,mouseUp)
numpty.addEventListener(MouseEvent.MOUSE_UP,mouseUp)
i tried to change the mouseUp by adding a number to the end of one to make it different but then i just got more error messages! its probably a simple problem to solve but i just dont have enough flash experience yet to figure it out.
thanks -
MULTIPLE-ROW drag and drop between 2 ALV grids
Hi,
Can anybody help me with acheiving MULTIPLE-ROW drag and drop functionality between 2 ALV grids.hi Prakash,
Actually I'm trying to develop multiple drag and drop between 2 ALV's. To understand the events properly, I started working on this sample program where it uses 1 ALV and splits it into 2 and uses single row drag and drop between them. Now I'm making it to work for multiple drag and drop, so that I can use it on my application. This is the code which I'm working on..

Why does not drag and drop work?!
Hello,
I am trying to implent a drag and drop from a table to an icon representing a trash.
The drop handler fails in converting the selected rows to a list:
com.sun.el.MethodExpressionImpl@87d9c00d javax.el.ELException: java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List
Could you help me to understand why? Below are the details.
This is the af:table:
<af:table var="row" rowBandingInterval="0" id="t1"
value="#{bindings.MyView1.collectionModel}"
rowSelection="multiple"
columnStretching="last"
horizontalGridVisible="false"
verticalGridVisible="false" fetchSize="-1"
autoHeightRows="6" width="190"
disableColumnReordering="true">
<af:column sortable="true" headerText="Entry" id="c1"
align="start">
<af:outputText value="#{row.Description}" id="ot1"/>
</af:column>
<af:dragSource actions="MOVE" defaultAction="MOVE"
discriminant="delete"/>
</af:table>
This is the drop area:
<af:image source="Images/empty_trash_32.png" id="i2">
<af:dropTarget dropListener="#{backingBeanScope.DropHandlerBean.dropHandler}"
actions="MOVE">
<af:dataFlavor flavorClass="org.apache.myfaces.trinidad.model.RowKeySet"
discriminant="delete"/>
</af:dropTarget>
</af:image>
This is the failing listener listener (the failing point is bold):
public DnDAction dropHandler(DropEvent dropEvent) {
DnDAction dnda = DnDAction.NONE;
if (dropEvent.getProposedAction() == DnDAction.MOVE) { // delete
RichTable table = (RichTable)dropEvent.getDragComponent();
//determine the rows that are dragged over
Transferable t = dropEvent.getTransferable();
//when looking for data, use the same discriminator as defined
//on the drag source
DataFlavor<RowKeySet> df =
DataFlavor.getDataFlavor(RowKeySet.class, "delete");
RowKeySet rks = t.getData(df);
if (rks == null) {
return DnDAction.NONE;
Iterator iter = rks.iterator();
while (iter.hasNext()) {
//get next selected row key
System.out.println(rks.toArray().length); // the number of selected rows is ok
List key = (List)iter.next(); // here gives: java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List
//make row current so we can access it
table.setRowKey(key);
//the table model represents its row by the ADF binding class,
//which is JUCtrlHierNodeBinding
JUCtrlHierNodeBinding rowBinding =
(JUCtrlHierNodeBinding)table.getRowData();
Row row = (Row)rowBinding.getRow();
//delete row;
row.remove();
//activate animation
dnda = DnDAction.MOVE;
return dnda;
thanks.I did try, I obtained this:
java.lang.NullPointerException
Why NullPointerException?
I don't know if this helps, but consider that the collection model comes from a ViewObject built on three EOs with many fields, although the table only shows one column.
This is the Iterator in my pageDef:
<table IterBinding="MyView1Iterator" id="MyView1">
<AttrNames>
<Item Value="Cod1"/>
<Item Value="Cod2"/>
<Item Value="Cod3"/>
<Item Value="Cod4"/>
<Item Value="Description"/>
<Item Value="Cod5"/>
</AttrNames>
</table>
Any idea?
I will see the Key content with the debugger.
