  • Stop jQuery animation prematurely

    - by jcovert
    Hi, I'm trying to fadeIn and fadeOut a transparent png using JQuery. Of course, it looks slick in Firefox, but significantly less than acceptable in IE (7 and 8). It's a known bug with IE, and unfortunately there doesn't seem to be much of a workaround. Basically what I'm doing is place a semi-transparent white rectangle over an image to make the image appear 'in the background'. I want to do this smoothly, and that's where fadeIn comes in. Because of the IE bug, however, I've been forced to fadeIn a completely opaque white rectangle over the image instead, making it unfortunately disappear. While this looks significantly better and is ALMOST what I'm looking for, it's still not acceptable. The user needs to be able to see SOME image on the page, albeit in the background. So my question is this: Is there a way to stop the fadeIn function (or any jquery animation, really) after animating for 75% of its expected animation time? This would leave my image 75% mixed the white rectangle, and I wouldn't have to deal with IE's nasty transparent png bug. Thanks!

  • Java Stop Server Thread

    - by ikurtz
    the following code is server code in my app: private int serverPort; private Thread serverThread = null; public void networkListen(int port){ serverPort = port; if (serverThread == null){ Runnable serverRunnable = new ServerRunnable(); serverThread = new Thread(serverRunnable); serverThread.start(); } else { } } public class ServerRunnable implements Runnable { public void run(){ try { //networkConnected = false; //netMessage = "Listening for Connection"; //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); ServerSocket serverSocket = new ServerSocket(serverPort, backlog); commSocket = serverSocket.accept(); serverSocket.close(); serverSocket = null; //networkConnected = true; //netMessage = "Connected: " + commSocket.getInetAddress().getHostAddress() + ":" + //commSocket.getPort(); //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); } catch (IOException e){ //networkConnected = false; //netMessage = "ServerRunnable Network Unavailable"; //System.out.println(e.getMessage()); //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); } } } The code sort of works i.e. if im attempting a straight connection both ends communicate and update. The issue is while im listening for a connection if i want to quit listening then the server thread continues running and causes problems. i know i should not use .stop() on a thread so i was wondering what the solution would look like with this in mind? EDIT: commented out unneeded code.

  • "Phased" execution of functions in javascript

    - by FK82
    Hey there! This is my first post on stackoverflow, so please don't flame me too hard if I come across like a total nitwit or if I'm unable ot make myself perfectly clear. :-) Here's my problem: I'm trying to write a javascript function that "ties" two functions to another by checking the first one's completion and then executing the second one. The easy solution to this obviously would be to write a meta function that calls both functions within it's scope. However, if the first function is asynchronous (specifically an AJAX call) and the second function requires the first one's result data, that simply won't work. My idea for a solution was to give the first function a "flag", i.e. making it create a public property "this.trigger" (initialized as "0", set to "1" upon completion) once it is called; doing that should make it possible for another function to check the flag for its value ([0,1]). If the condition is met ("trigger == 1") the second function should get called. The following is an abstract example code that I have used for testing: <script type="text/javascript" > /**/function cllFnc(tgt) { //!! first function this.trigger = 0 ; var trigger = this.trigger ; var _tgt = document.getElementById(tgt) ; //!! changes the color of the target div to signalize the function's execution _tgt.style.background = '#66f' ; alert('Calling! ...') ; setTimeout(function() { //!! in place of an AJAX call, duration 5000ms trigger = 1 ; },5000) ; } /**/function rcvFnc(tgt) { //!! second function that should get called upon the first function's completion var _tgt = document.getElementById(tgt) ; //!! changes color of the target div to signalize the function's execution _tgt.style.background = '#f63' ; alert('... Someone picked up!') ; } /**/function callCheck(obj) { //alert(obj.trigger ) ; //!! correctly returns initial "0" if(obj.trigger == 1) { //!! here's the problem: trigger never receives change from function on success and thus function two never fires alert('trigger is one') ; return true ; } else if(obj.trigger == 0) { return false ; } } /**/function tieExc(fncA,fncB,prms) { if(fncA == 'cllFnc') { var objA = new cllFnc(prms) ; alert(typeof objA + '\n' + objA.trigger) ; //!! returns expected values "object" and "0" } //room for more case definitions var myItv = window.setInterval(function() { document.getElementById(prms).innerHTML = new Date() ; //!! displays date in target div to signalize the interval increments var myCallCheck = new callCheck(objA) ; if( myCallCheck == true ) { if(fncB == 'rcvFnc') { var objB = new rcvFnc(prms) ; } //room for more case definitions window.clearInterval(myItv) ; } else if( myCallCheck == false ) { return ; } },500) ; } </script> The HTML part for testing: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/strict.dtd > <html> <head> <script type="text/javascript" > <!-- see above --> </script> <title> Test page </title> </head> <body> <!-- !! testing area --> <div id='target' style='float:left ; height:6em ; width:8em ; padding:0.1em 0 0 0; font-size:5em ; text-align:center ; font-weight:bold ; color:#eee ; background:#fff;border:0.1em solid #555 ; -webkit-border-radius:0.5em ;' > Test Div </div> <div style="float:left;" > <input type="button" value="tie calls" onmousedown="tieExc('cllFnc','rcvFnc','target') ;" /> </div> <body> </html> I'm pretty sure that this is some issue with javascript scope as I have checked whether the trigger gets set to "1" correctly and it does. Very likely the "checkCall()" function does not receive the updated object but instead only checks its old instance which obviously never flags completion by setting "this.trigger" to "1". If so I don't know how to address that issue. Anyway, hope someone has an idea or experience with this particular kind of problem. Thanks for reading! FK

  • What is considered a long execution time?

    - by stjowa
    I am trying to figure out just how "efficient" my server-side code is. Using start and end microtime(true) values, I am able to calculate the time it took my script to run. I am getting times from .3 - .5 seconds. These scripts do a number of database queries to return different values to the user. What is considered an efficient execution time for PHP scripts that will be run online for a website? Note: I know it depends on exactly what is being done, but just consider this a standard script that reads from a database and returns values to the user. Also, I look at Google and see them search the internet in .15 seconds and I feel like my script is crap. Thanks.

  • Negative execution time

    - by FinalArt2005
    Hello, I wrote a little program that solves 49151 sudoku's within an hour for an assignment, but we had to time it. I thought I'd just let it run and then check the execution time, but it says -1536.087 s. I'm guessing it has to do with the timer being some signed dataype or something, but I have no idea what datatype is used for the timer in the console (code::blocks console, I'm not sure if this is actually a separate console, or just a runner that runs the terminal from the local operating system), so I can't check what the real time was. I'd rather not run this again with some coded timer within my program, since I'd like to be able to use my pc again now. Anybody have any idea what this time could be? It should be somewhere between 40 and 50 minutes, so between 2400 and 3000 seconds. Regards, Erik

  • Slightly different execution times between python2 and python3

    - by user557634
    Hi. Lastly I wrote a simple generator of permutations in python (implementation of "plain changes" algorithm described by Knuth in "The Art... 4"). I was curious about the differences in execution time of it between python2 and python3. Here is my function: def perms(s): s = tuple(s) N = len(s) if N <= 1: yield s[:] raise StopIteration() for x in perms(s[1:]): for i in range(0,N): yield x[:i] + (s[0],) + x[i:] I tested both using timeit module. My tests: $ echo "python2.6:" && ./testing.py && echo "python3:" && ./testing3.py python2.6: args time[ms] 1 0.003811 2 0.008268 3 0.015907 4 0.042646 5 0.166755 6 0.908796 7 6.117996 8 48.346996 9 433.928967 10 4379.904032 python3: args time[ms] 1 0.00246778964996 2 0.00656183719635 3 0.01419159912 4 0.0406293644678 5 0.165960511097 6 0.923101452814 7 6.24257639835 8 53.0099868774 9 454.540967941 10 4585.83498001 As you can see, for number of arguments less than 6, python 3 is faster, but then roles are reversed and python2.6 does better. As I am a novice in python programming, I wonder why is that so? Or maybe my script is more optimized for python2? Thank you in advance for kind answer :)

  • How to stop worker threads in a multithreaded Windows service on service stop

    - by RobW
    I have a Windows service that uses the producer/consumer queue model with multiple worker threads processing tasks off a queue. These tasks can be very long running, in the order of many minutes if not hours, and do not involve loops. My question is about the best way to handle the service stop to gracefully end processing on these worker threads. I have read in another SO question that using thread.Abort() is a sign of bad design, but it seems that the service OnStop() method is only given a limited amount of time to finish before the service is terminated. I can do sufficient clean-up in the catch for ThreadAbortException (there is no danger of inconsistent state) so calling thread.Abort() on the worker threads seems OK to me. Is it? What are the alternatives?

  • java Process stop entire process tree

    - by ages04
    I am using Java Runtime to run commands, including certain CVS commands. I use: process = runtime.exec ("cmd /C cvs..."); format for running the Process in Java I need to have the option of stopping it. For this I use the Java Process destroy method process.destroy(); However only the cmd is stopped not the cvs process. It continues to run as a separate process without the cmd process as the parent. There are many references to this on the internet, but I haven't found any satisfactory solution. Thanks

  • Reading train stop display names from a resource bundle

    - by Frank Nimphius
    v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} In Oracle JDeveloper 11g R1, you set the display name of a train stop of an ADF bounded task flow train model by using the Oracle JDeveloper Structure Window. To do so Double-click onto the bounded task flow configuration file (XML) located in the Application Navigator so the task flow diagram open In the task flow diagram, select the view activity node for which you want to define the display name. In the Structure Window., expand the view activity node and then the train-stop node therein Add the display name element by using the right-click context menu on the train-stop node, selecting Insert inside train-stop > Display Name Edit the Display Name value with the Property Inspector Following the steps outlined above, you can define static display names – like "PF1" for page fragment 1 shown in the image below - for train stops to show at runtime. In the following, I explain how you can change the static display string to a dynamic string that reads the display label from a resource bundle so train stop labels can be internationalized. There are different strategies available for managing message bundles within an Oracle JDeveloper project. In this blog entry, I decided to build and configure the default properties file as indicated by the projects properties. To learn about the suggested file name and location, open the JDeveloper project properties (use a right mouse click on the project node in the Application Navigator and choose Project Properties. Select the Resource Bundle node to see the suggested name and location for the default message bundle. Note that this is the resource bundle that Oracle JDeveloper would automatically create when you assign a text resource to an ADF Faces component in a page. For the train stop display name, we need to create the message bundle manually as there is no context menu help available in Oracle JDeveloper. For this, use a right mouse click on the JDeveloper project and choose New | General | File from the menu and in the opened dialog. Specify the message bundle file name as the name looked up before in the project properties Resource Bundle option. Also, ensure that the file is saved in a directory structure that matches the package structure shown in the Resource Bundle dialog. For example, you would save the properties file in the View Project's src > adf > sample directory if the package structure was "adf.sample" (adf.sample.ViewControllerBundle). Edit the properties file and define key – values pairs for the train stop component. In the sample, such key value pairs are TrainStop1=Train Stop 1 TrainStop2=Train Stop 2 TrainStop3=Train Stop 3 Next, double click the faces-config.xml file and switch the opened editor to the Overview tab. Select the Application category and press the green plus icon next to the Resource Bundle section. Define the resource bundle Base Name as the package and properties file name, for example adf.sample.ViewControllerBundle Finally, define a variable name for the message bundle so the bundle can be accessed from Expression Language. For this blog example, the name is chosen as "messageBundle". <resource-bundle>   <base-name>adf.sample.ViewControllerBundle</base-name>   <var>messageBundle</var> </resource-bundle> Next, select the display-name element in the train stop node (similar to when creating the display name) and use the Property Inspector to change the static display string to an EL expression referencing the message bundle. For example: #{messageBundle.TrainStop1} At runtime, the train stops now show display names read from a message bundle (the properties file).

  • SQL SERVER – SSMS: Top Object and Batch Execution Statistics Reports

    - by Pinal Dave
    The month of June till mid of July has been the fever of sports. First, it was Wimbledon Tennis and then the Soccer fever was all over. There is a huge number of fan followers and it is great to see the level at which people sometimes worship these sports. Being an Indian, I cannot forget to mention the India tour of England later part of July. Following these sports and as the events unfold to the finals, there are a number of ways the statisticians can slice and dice the numbers. Cue from soccer I can surely say there is a team performance against another team and then there is individual member fairs against a particular opponent. Such statistics give us a fair idea to how a team in the past or in the recent past has fared against each other, head-to-head stats during World cup and during other neutral venue games. All these statistics are just pointers. In reality, they don’t reflect the calibre of the current team because the individuals who performed in each of these games are totally different (Typical example being the Brazil Vs Germany semi-final match in FIFA 2014). So at times these numbers are misleading. It is worth investigating and get the next level information. Similar to these statistics, SQL Server Management studio is also equipped with a number of reports like a) Object Execution Statistics report and b) Batch Execution Statistics reports. As discussed in the example, the team scorecard is like the Batch Execution statistics and individual stats is like Object Level statistics. The analogy can be taken only this far, trust me there is no correlation between SQL Server functioning and playing sports – It is like I think about diet all the time except while I am eating. Performance – Batch Execution Statistics Let us view the first report which can be invoked from Server Node -> Reports -> Standard Reports -> Performance – Batch Execution Statistics. Most of the values that are displayed in this report come from the DMVs sys.dm_exec_query_stats and sys.dm_exec_sql_text(sql_handle). This report contains 3 distinctive sections as outline below.   Section 1: This is a graphical bar graph representation of Average CPU Time, Average Logical reads and Average Logical Writes for individual batches. The Batch numbers are indicative and the details of individual batch is available in section 3 (detailed below). Section 2: This represents a Pie chart of all the batches by Total CPU Time (%) and Total Logical IO (%) by batches. This graphical representation tells us which batch consumed the highest CPU and IO since the server started, provided plan is available in the cache. Section 3: This is the section where we can find the SQL statements associated with each of the batch Numbers. This also gives us the details of Average CPU / Average Logical Reads and Average Logical Writes in the system for the given batch with object details. Expanding the rows, I will also get the # Executions and # Plans Generated for each of the queries. Performance – Object Execution Statistics The second report worth a look is Object Execution statistics. This is a similar report as the previous but turned on its head by SQL Server Objects. The report has 3 areas to look as above. Section 1 gives the Average CPU, Average IO bar charts for specific objects. The section 2 is a graphical representation of Total CPU by objects and Total Logical IO by objects. The final section details the various objects in detail with the Avg. CPU, IO and other details which are self-explanatory. At a high-level both the reports are based on queries on two DMVs (sys.dm_exec_query_stats and sys.dm_exec_sql_text) and it builds values based on calculations using columns in them: SELECT * FROM    sys.dm_exec_query_stats s1 CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 WHERE   s2.objectid IS NOT NULL AND DB_NAME(s2.dbid) IS NOT NULL ORDER BY  s1.sql_handle; This is one of the simplest form of reports and in future blogs we will look at more complex reports. I truly hope that these reports can give DBAs and developers a hint about what is the possible performance tuning area. As a closing point I must emphasize that all above reports pick up data from the plan cache. If a particular query has consumed a lot of resources earlier, but plan is not available in the cache, none of the above reports would show that bad query.

  • PowerShell to fetch a SQL Execution Plan

    - by Rob Farley
    With PowerShell becoming the scripting language of choice for many people, I’ve occasionally wondered about using it to analyse execution plans. After all, an execution plan is just XML, and PowerShell is just one tool which will very easily handle xml. The thing is – there’s no Get-SqlPlan cmdlet available, which has frustrated me in the past. Today I figured I’d make one. I know that I can write T-SQL to get an execution plan using SET SHOWPLAN_XML ON, but the problem is that this must be the only statement in a batch. So I used go, and a couple of newlines, and whipped up the following one-liner: function Get-SqlPlan([string] $query, [string] $server, [string] $db) { return ([xml] (invoke-sqlcmd -Server $server -Database $db -Query "set showplan_xml on;`ngo`n$query").Item( 0)) } (but please bear in mind that I have the SQL Snapins installed, which provides invoke-sqlcmd) To use this, I just do something like: $plan = get-sqlplan "select name from Production.Product" "." "AdventureWorks" And then find myself with an easy way to navigate through an execution plan! At some point I should make the function more robust, but this should be a good starter for any SQL PowerShell enthusiasts (like Aaron Nelson) out there.

  • Possible Data Execution Prevention problem in Windows 7

    - by Joel in Gö
    I have a serious problem with my .Net program. It calls a native dll, and then crashes instantly because it can't find a native method. This is behaviour we have seen before, whereby the C# compiler, in its infinite wisdom, sets the flag that the program is DEP compatible, even if it calls a native dll which patently is not. We have the standard workaround for this, where the flag is set to Not DEP Compatible in a post-build step, and this works fine. Everywhere except on my machine. I have Windows 7 32bit, and the program works fine on the Win 7 64bit machines that we have, as well as on Vista and XP; we have not yet been able to check on another Win7 32bit. However, on my machine the DataExecutionPolicy_SupportPolicy is 0, i.e. we have successfully switched DEP off. The dll in question also works fine when called from a native program. We are running out of ideas... any help would be much appreciated!

  • Controlled execution of computationally expensive tasks

    - by Sergio
    Say you have an application where a user is typing some text and as she types you'd want to perform some expensive computations in the background (related to the text that is being typed). Although you would like to do lots of things, your main priority is that the system responsiveness stay at acceptable levels so the user doesn't notice such a heavy load. Is there a way (ideally platform/language independent) to control what algorithms should be executed in the background based on the system load and responsiveness?

  • is there an equivalent of a trigger for general stored procedure execution on sql server

    - by Arj
    Hi All, Hope you can help. Is there a way to detect when a stored proc is being run on SQL Server without altering the SP itself? Here's the requirement. We need to track users running reports from our enterprise data warehouse as the core product we use doesn't allow for this. Both core product reports and a slew of in-house ones we've added all return their data from individual stored procs. We don't have a practical way of altering the parts of the product webpages where reports are called from. We also can't change the stored procs for the core product reports. (It would be trivial to add a logging line to the start/end of each of our inhouse ones). What I'm trying to find therefore, is whether there's a way in SQL Server (2005 / 2008) to execute a logging stored proc whenever any other stored procedure runs, without altering those stored procedures themselves. We have general control over the SQL Server instance itself as it's local, we just don't want to change the product stored procs themselves. Any one have any ideas? Is there a kind of "stored proc executing trigger"? Is there an event model for SQL Server that we can hook custom .Net code into? (Just to discount it from the start, we want to try and make a change to SQL Server rather than get into capturing the report being run from the products webpages etc) Thoughts appreciated Thanks

  • Trigger local program execution from browser

    - by DroidIn.net
    First and foremost: I know it's not right or even good thing to do but my current customer will not cave in. So here's what he is asking for (this is for in-house-behind-a-firewall-etc project). In the web report I need to supply a link which points to the executable script that lives on the universally mapped location (network file server). When user clicks on it it is expected to run on the local client starting local executable which should be pre-installed on the client's box. It should be agnostic to OS (Windows or Linux) and the browser used. Customer doesn't mind to click on angry pop-up alerts but he wants to do it once per client browser (or at minimum - session). QUESTION: Will trusted Java applet be able to do it? Or is the any other (better, simpler) ways of achieving the same? ActiveX control is out of question

We have general control over the SQL Server instance itself as it's local, we just don't want to change the product stored procs themselves. Any one have any ideas? Is there a kind of "stored proc executing trigger"? Is there an event model for SQL Server that we can hook custom .Net code into? (Just to discount it from the start, we want to try and make a change to SQL Server rather than get into capturing the report being run from the products webpages etc) Thoughts appreciated Thanks

  • How Does Differential Execution Work?

    - by Brian
    I've seen a few mentions of this on SO, but staring at Wikipedia and at an MFC dynamic dialog demo did nothing to enlighten me. Can someone please explain this? Learning a fundamentally different concept sounds nice. Edit: I think I'm getting a better feel for it. I guess I just didn't look at the source code carefully enough the first time. I have mixed feelings about DE at this point. On the one hand, it can make certain tasks considerably easier. On the other hand, getting it up and running (i.e. setting it up in your language of choice) is not easy (I'm sure it would be if I understood it better)...though I guess the toolbox for it need only be made once, then expanded as necessary. I think in order to really understand it, I'll probably need to try implimenting it in another language.

  • C# Step by Step Execution

    - by Sheldon
    Hi. I'm building an app that uses and scanner API and a image to other format converter. I have a method (actually a click event) that do this: private void ButtonScan&Parse_Click(object sender, EventArgs e) { short scan_result = scanner_api.Scan(); if (scan_result == 1) parse_api.Parse(); // This will check for a saved image the scanner_api stores on disk, and then convert it. } The problem is that the if condition (scan_result == 1) is evaluated inmediatly, so it just don't work. How can I force the CLR to wait until the API return the convenient result. NOTE Just by doing something like: private void ButtonScan&Parse_Click(object sender, EventArgs e) { short scan_result = scanner_api.Scan(); MessageBox.Show("Result = " + scan_result); if (scan_result == 1) parse_api.Parse(); // This will check for a saved image the scanner_api stores on disk, and then convert it. } It works and display the results. Is there a way to do this, how? Thank you very much!
