Possible to receive event on disabled frame?

I have an application that have many JFrame popups. After 15 minutes, the app will automatically lock all windows calling their setEnabled(false). A Lock window is displayed let user to relogin.
When user click on any of open frame, I would like to display Locked frame by user's cursor. However, the inactive windows are not receiving any mouse event.
Anyone have good idea on how to intercept mouse event on disabled JFrame?
Thanks.

Added Jcombobox into awt.frame causing handling event function cannot receive event

Dear Sir,
I want to ask how an awt.Choice can set the number of rows that it can display, like the method setMaximumRowCount in JCombobox. Since I want to set more row can be displayed, but choice no any method can set. And I have tried to add Jcombobox into awt.frame, then, the handling event function cannot receive event for the right-top cornet button(minimize, maximum, close).
Best Regards,

please post a Short, Self Contained, Correct Example showing your problem.

Mouse Events on Disabled Buttons

Hi,
In my application I should make a disabled button to show a tool tip when mouse is entered onto it.
I'm using java.awt.container not Jcontainer.
I have searched in SDN forums and after reading some of the comments what I understood is �disabled Swing button can react to Mouse events but a disabled awt button can not react to mouse events�.
Is that true or did I not understand correctly?
And how would I be able to implement the required functionality in my
application?
Thanks.

Receiving Events from all nodes

Hi
I have a cluster which contains n nodes.Each node contains a partitioned
cache service with a cache called CacheA. If an object is inserted it is inserted to any one
of the n nodes based upon some distribution algorithm and registered event listeners for that
particular cache are triggered on that node.
But is there a way to trigger an event in all n nodes irrespective of the physical location of insertion?
If so, how to go about it? Any documents or help regarding this will be helpful to me.
Thanks ,
Ramyaa.

Hi Mark,
AFAIK the guarantees for listeners are the following:
Listeners registered inside the TCMP cluster (full-fledged cluster nodes, not in an *Extend client):
- sychronous listeners (listeners implementing MapListenerSupport.SynchronousListener or those wrapped in MapListenerSupport.WrapperSynchronousListener) guaranteed to get notifications before the thread executing the triggering cache operation (if there was one) returns from the cache operation. I am not 100% sure, but I strongly believe that the cache operation returning also means that the synchronous listeners also completed, judging from the documentation of SynchronousListener, which would also mean that an ack for synchronous listeners is only sent back from the listener node once all synchronous listeners completed.
- asynchronous listeners are guaranteed to be notified but this notification will not be guaranteed to happen before the triggering cache operation completed
The only exception to that is if the listener node drops out of the cluster according to the owner of the entry which changed, or if the service for some reason dies on the listener node; about both you will get a notification so that you know that you are no more receiving events.
In both cases (sync/async) the entry owner notifies the node the listener is registered on, and I believe it will retry sending the event until it is ack-ed to be received. I don't know whether the ACK comes from the TCMP layer or from the particular service in the async case, I would guess the service.
The listener node will do duplicate detection on the delivered events per listener so that it will find out if it already invoked the listener once with the same event.
No transactions are provided for listeners, so even if an exception happens in a synchronous listener, it won't roll back the entry change.
For *Extend clients, I believe there are no guarantees for delivering events arriving while the client failed over after a broken connection.
For the staying connected case, and I don't know what the situation is, but I would expect synchronous listeners are not supported over *Extend, and async exactly one notification seems possible (again, while the client is connected), but I am not sure about this.
Best regards,
Robert

I don't know if it is the best solution but you could filter the results to just that client's answers on the summary tab and then PDF that.

Is it possible to enter events into a specific iCal calendar, then print a list of those events with the name and date on a single sheet?

Is it possible to enter events into a specific iCal calendar, then print a list of those events with the name and date on a single sheet? I don't need the calendar grid. I just want a list of events on a particular calendar, and their dates. Is that possible?

Not easily. Two possibilities:
1) If all the events have some common feature (eg you have included "XXX" in all the summaries), search for that feature then select and copy the found items at the bottom of the window. You can then paste them into TextEdit or a spreadsheet for printing
2) You could write an Applescript to locate the events and write them into a text file for printing.
The first one will probably give you what you want.

You purchased a "hacked" iPhone(hacked to unlock it) from a non-official source for iPhones. Unfortunately, that's the risk you take when you purchase from a non-official source. There is no way to get your phone officially unlocked, & all warranty & support has been voided. Sorry, but you don't have any good choices here. Your best bet is to go back to Carrefour Supermarket & get your money back, then purchase an iPhone from an official source. If they won't give you your money back, have them "fix" your phone...they will have to "hack" it again. Good luck.

Every morning receive Event Source MSExchange Common ID 4999

This is an Intel machine so we are not sure why there is “AMD64” in the details - This Event does not seem to cause any problem that we can detect.

Hi,
It seems that the issue is related to the special characters in the database name cause an

Receiving events from event hub was blocked.

In our Cloud Service project, we have 2 instances for work role (deploy to Azure), the work role is consume events from the EventHub using EventProcessorHost(host name is RoleInstance name).
For sending events:
    var
client = EventHubClient.CreateFromConnectionString(serviceBusConnectionString,
hubName);
while (true)
var eventData =
new
EventData(Encoding.UTF8.GetBytes("test"))
{PartitionKey = "key"};
                    eventData.Properties.Add("time",
DateTime.UtcNow);
                client.SendAsync(eventData).Wait();
                Thread.Sleep(50);
Each 50ms, we send one event (event1, 2,3 …….);
For receiving data:
public
async
Task ProcessEventsAsync(PartitionContext
context, IEnumerable<EventData>
events)
            //when
we get the event, so we can view the log
Trace.WriteLine(“got events”);
foreach (var
eventData in events)
                // handle the event
Task.Delay(12000).Wait();
await ContextCheckpointAsync(context);
We add the
delay for event operation.
It seems that we cannot receive data in time from the log, seems event6 was blocked for the Event5 delay, after the 12ms, we can receive event6 from the EventHub, and the Event6
delay is 40s(from the log, we send event6 to Hub at 35:10, but we get from Hub at 35:50),
So I wonder to know the maximum number of threads are working on processing fot the EventProcessorHost? Depends on the Partitions?
And is there any way to receiving events in time?

Hi Jordan
Since Task.Delay call blocks the callback, host won't hand over new events until you're done with the current batch. This is due to order guarantee of the events delivered, i.e. host should process the events in order from the same partition.
If event process is taking so long then you should consider to move process job into a separate thread so host can deliver new batch of events while thread is working on the previous batch.

Is is possible to open event lists from different tracks at the same time in Logic Pro 9?

Is it possible to open event lists from two difference tracks in an arrangement at the same time in Logic Pro 9?
When I switch between tracks the event list swiches as well. Thanks in advance.

If you deselect the litte chain link icon in the event list window, it will no longer follow your region selection and you can openas many as you need. Also you can select multiple regions and see the inthe SAME window if you select to show multiple regions, and you can have the notes shown in their respective track colors.

We stopped receiving event about lockout users after we installed rollup 4 for tmg with sp2

We have implemented Account Lockout Feature in TMG 2010 (http://www.ntsystems.it/post/ActiveSync-ForeFront-TMG-and-AccountLockoutThreshold.aspx). We configured
alert definition to send alert when problem occure. After we installed rollup 4 we stopped receiving event about this probloem ("The limit of consecutive logon failures has been reached...."). How can we resolve this problem? We have implented
a script which send this information automatically to user with problem. This is very important for us.
Event description:
Source: Microsoft Forefront TMG Web
Event ID: 32581
Level: Error
Text: limit for consecutive logon failures has been reached. Additional logon attempts by domain.local\user.name will be automatically rejected for the next 300 seconds

Hi,
Before going further troubleshooting, we should confirm if account lockout works fine now.
Please refer to the article below to check some limitations on this function.
http://blogs.technet.com/b/isablog/archive/2012/11/01/using-the-account-lockout-feature-in-tmg-2010.aspx
Is there any other different information after you install Rollup 4? Or what something else do you change during update to RU4?

Is it possible to receive a String[] back into stored procedure?

Hi,
Is it possible to return String [] into plsql procedure?
I have a class :
class CreditCard {
public static String cc (String args []) []

I load it into the database and then create a plsql procedure:
CREATE OR REPLACE PROCEDURE check_credit(

exp_month IN          VARCHAR2,
exp_year      IN          VARCHAR2,

trying to compile it gives me:
20/1 PLS-00311: the declaration of "CreditCard.cc(java.lang.String[])
return java.lang.String[]" is incomplete or malformed
Is it possible to receive a String[] back into stored procedure?
Thanks

I don't think you can use a String Array directly, you have to use an oracle.sql.ARRAY.
You use the oracle.sql.ARRAY parameter in Java as an OUT parameter in the stored procedure. You need to use an ArrayDescriptor which requires a corresponding Oracle Nested Table type.
Try something like the following:
First the Nested Table Type:
     CREATE OR REPLACE TYPE
     TBL_STRINGS AS TABLE OF VARCHAR2(999);
Then the Java method:
public static void getStrings(oracle.sql.ARRAY[] theStrings) //has to be an array of oracle.sql.ARRAY's as we use it as an OUT parameter
try
     //get a connection
     Connection conn = DriverManager.getConnection("jdbc:default:connection:");
     String [] colours = new String []{"RED", "GREEN", "GOLD"};
ArrayDescriptor desc = ArrayDescriptor.createDescriptor("TBL_STRINGS", conn);
theStrings[0] = new oracle.sql.ARRAY(desc, conn, colours);
     conn.close();
catch (SQLException sqle)
          //report error
Then the call spec:
     PROCEDURE GET_STRINGS(p_the_strings     OUT     TBL_STRINGS)
     AS LANGUAGE JAVA
     NAME 'mypackage.MyClass.getStrings(oracle.sql.ARRAY[])';

Is it possible to remove blemishes from video frames with photoshop cc?

Is it possible to remove blemishes from video frames with photoshop cc?

Again, show us reference screenshots and we will advise. Otherwise this could become an endless theoretical discussion. Depending on what you want to do you can import the video directly using Layer --> New Video Layer e.g. when covering up fied spots with a brush blob on a layer on top of the footage, but you may also need to create separate layers for each frame using the Frames to Layers script so you can paint on each of them individually. There's really too much we don't know and the possibilities are potentially infinite...

Waiting for receiving whole data in data receive event of serila port

0down votefavorite
I want to migrate one VB6 project to C#. In VB6 project MSCOMM control is used for serial port communication. Instead of using same control in C# application I have used serial port class.
Initially I am sending 4 consecutive commands to serial port. When I tried to debug the code I found
DataReceive event is working in separate thread.
I need 15 bytes response for first command 17 bytes response to second command.
But as we know DataReceive event for one byte also.
I want to get whole 15 bytes response for first command and then want to send second command.
I have tried following code.
private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
if (serialPort1.ReceivedBytesThreshold > sent_command.Length)
string data = serialPort1.ReadExisting();
int bufferLengh = data.Length;
string output_str;
char[] array = data.ToCharArray();
string final = "";
foreach (var i in array)
string hex = String.Format("{0:X}", Convert.ToInt32(i));
final += hex.Insert(0, "") ;
final = final.TrimEnd();
output_str = final;
MessageBox.Show(output_str);
Using above code I am getting data filled with one or two bytes and rest data bytes as "0" but data byte length is correct. (for first command it is 15 and second command 17 bytes)
Or sometimes data = ""
My question is how to wait in data receive event to get whole response and then it will receive the response for second command.
In VB6 application one polling timer is used.
If I used a timer in C# application then in that timer event timeout exception get fired and data receive event does not get fired.
Please help me to resolve this.
Thanks in advance.
