  • activemq-maven-plugin ignore files in classpath?

    - by Oscar Chan
    I have been trying to get activemq-maven-plugin to run activemq with configuration in classpath of the bundle. However, I don't have much luck. It seems that the activemq-maven-plugin just ignore resources (resources/main/conf/activemq.properties) the local bundle. I checked the jar and target/classes and they are built into the right local. I am able to get plugin to run (mvn activemq:run) if I take out the PropertyPlaceholderConfigurer bean in the activemq.xml Did I do anything wrong? Here is the output [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Failed to start ActiveMQ Broker Embedded error: Could not load properties; nested exception is java.io.FileNotFoundException: class path resource [conf/activemq.properties] cannot be opened because it does not exist [INFO] ------------------------------------------------------------------------ [INFO] For more information, run Maven with the -e switch [INFO] ------------------------------------------------------------------------ [INFO] Total time: 2 seconds [INFO] Finished at: Mon May 03 15:56:05 PDT 2010 [INFO] Final Memory: 11M/79M [INFO] ------------------------------------------------------------------------ Here is the pom.xml, which I specific the plugin to look up activemq.xml via file, that works.

  • How to fix flicker when using Webkit transforms & transitions

    - by gargantaun
    I have a very simple demo working that uses Webkit transforms and transitions for smooth horizontal scrolling between 'panels' (divs). The reason I want to go this route as opposed to a Javascript driven system is that it's for the iPad and Javascript performance is quite poor, but the css transforms and transitions are smooth as silk. Sadly though, I'm getting a lot of flicker on the iPad with my Demo. You can see the demo here You'll need safari or and iPad to see it in action. I've never seen this happening in any of the demos for transforms and transitions so I'm hopeful that this is fixable. Anyway here's the code that powers the thing.... The HTML looks like this. <html> <head> <title>Swipe Demo</title> <link href="test.css" rel="stylesheet" /> <link href="styles.css" rel="stylesheet" /> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript" src="functions.js"></script> <script type="text/javascript" src="swiping.js"></script> </head> <body> <div id="wrapper"> <div class='panel one'> <h1>This is panel 1</h1> </div> <div class='panel two'> <h1>This is panel 2</h1> </div> <div class='panel three'> <h1>This is panel 3</h1> </div> <div class='panel four'> <h1>This is panel 4</h1> </div> </div> </body> </html> The CSS looks like this body, html { padding: 0; margin: 0; background: #000; } #wrapper { width: 10000px; -webkit-transform: translateX(0px); } .panel { width: 1024px; height: 300px; background: #fff; display: block; float: left; position: relative; } and the javascript looks like this // Mouse / iPad Touch var touchSupport = (typeof Touch == "object"), touchstart = touchSupport ? 'touchstart' : 'mousedown', touchmove = touchSupport ? 'touchmove' : 'mousemove', touchend = touchSupport ? 'touchend' : 'mouseup'; $(document).ready(function(){ // set top and left to zero $("#wrapper").css("top", 0); $("#wrapper").css("left", 0); // get total number of panels var panelTotal; $(".panel").each(function(){ panelTotal += 1 }); // Touch Start // ------------------------------------------------------------------------------------------ var touchStartX; var touchStartY; var currentX; var currentY; var shouldMove = false; document.addEventListener(touchstart, swipeStart, false); function swipeStart(event){ touch = realEventType(event); touchStartX = touch.pageX; touchStartY = touch.pageY; var pos = $("#wrapper").position(); currentX = parseInt(pos.left); currentY = parseInt(pos.top); shouldMove = true; } // Touch Move // ------------------------------------------------------------------------------------------ var touchMoveX; var touchMoveY; var distanceX; var distanceY; document.addEventListener(touchmove, swipeMove, false); function swipeMove(event){ if(shouldMove){ touch = realEventType(event); event.preventDefault(); touchMoveX = touch.pageX; touchMoveY = touch.pageY; distanceX = touchMoveX - touchStartX; distanceY = touchMoveY - touchStartY; movePanels(distanceX); } } function movePanels(distance){ newX = currentX + (distance/4); $("#wrapper").css("left", newX); } // Touch End // ------------------------------------------------------------------------------------------ var cutOff = 100; var panelIndex = 0; document.addEventListener(touchend, swipeEnd, false); function swipeEnd(event){ touch = (touchSupport) ? event.changedTouches[0] : event; var touchEndX = touch.pageX; var touchEndY = touch.pageY; updatePanelIndex(distanceX); gotToPanel(); shouldMove = false; } // -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- function updatePanelIndex(distance){ if(distanceX > cutOff) panelIndex -= 1; if(distanceX < (cutOff * -1)){ panelIndex += 1; } if(panelIndex < 0){ panelIndex = 0; } if(panelIndex >= panelTotal) panelIndex = panelTotal -1; console.log(panelIndex); } // -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- function gotToPanel(){ var panelPos = getTotalWidthOfElement($(".panel")) * panelIndex * -1; $("#wrapper").css("-webkit-transition-property", "translateX"); $("#wrapper").css("-webkit-transition-duration", "1s"); $("#wrapper").css("-webkit-transform", "translateX("+panelPos+"px)"); } }); function realEventType(event){ e = (touchSupport) ? event.targetTouches[0] : event; return e; }

  • How to count each digit in a range of integers?

    - by Carlos Gutiérrez
    Imagine you sell those metallic digits used to number houses, locker doors, hotel rooms, etc. You need to find how many of each digit to ship when your customer needs to number doors/houses: 1 to 100 51 to 300 1 to 2,000 with zeros to the left The obvious solution is to do a loop from the first to the last number, convert the counter to a string with or without zeros to the left, extract each digit and use it as an index to increment an array of 10 integers. I wonder if there is a better way to solve this, without having to loop through the entire integers range. Solutions in any language or pseudocode are welcome. Edit: Answers review John at CashCommons and Wayne Conrad comment that my current approach is good and fast enough. Let me use a silly analogy: If you were given the task of counting the squares in a chess board in less than 1 minute, you could finish the task by counting the squares one by one, but a better solution is to count the sides and do a multiplication, because you later may be asked to count the tiles in a building. Alex Reisner points to a very interesting mathematical law that, unfortunately, doesn’t seem to be relevant to this problem. Andres suggests the same algorithm I’m using, but extracting digits with %10 operations instead of substrings. John at CashCommons and phord propose pre-calculating the digits required and storing them in a lookup table or, for raw speed, an array. This could be a good solution if we had an absolute, unmovable, set in stone, maximum integer value. I’ve never seen one of those. High-Performance Mark and strainer computed the needed digits for various ranges. The result for one millon seems to indicate there is a proportion, but the results for other number show different proportions. strainer found some formulas that may be used to count digit for number which are a power of ten. Robert Harvey had a very interesting experience posting the question at MathOverflow. One of the math guys wrote a solution using mathematical notation. Aaronaught developed and tested a solution using mathematics. After posting it he reviewed the formulas originated from Math Overflow and found a flaw in it (point to Stackoverflow :). noahlavine developed an algorithm and presented it in pseudocode. A new solution After reading all the answers, and doing some experiments, I found that for a range of integer from 1 to 10n-1: For digits 1 to 9, n*10(n-1) pieces are needed For digit 0, if not using leading zeros, n*10n-1 - ((10n-1) / 9) are needed For digit 0, if using leading zeros, n*10n-1 - n are needed The first formula was found by strainer (and probably by others), and I found the other two by trial and error (but they may be included in other answers). For example, if n = 6, range is 1 to 999,999: For digits 1 to 9 we need 6*105 = 600,000 of each one For digit 0, without leading zeros, we need 6*105 – (106-1)/9 = 600,000 - 111,111 = 488,889 For digit 0, with leading zeros, we need 6*105 – 6 = 599,994 These numbers can be checked using High-Performance Mark results. Using these formulas, I improved the original algorithm. It still loops from the first to the last number in the range of integers, but, if it finds a number which is a power of ten, it uses the formulas to add to the digits count the quantity for a full range of 1 to 9 or 1 to 99 or 1 to 999 etc. Here's the algorithm in pseudocode: integer First,Last //First and last number in the range integer Number //Current number in the loop integer Power //Power is the n in 10^n in the formulas integer Nines //Nines is the resut of 10^n - 1, 10^5 - 1 = 99999 integer Prefix //First digits in a number. For 14,200, prefix is 142 array 0..9 Digits //Will hold the count for all the digits FOR Number = First TO Last CALL TallyDigitsForOneNumber WITH Number,1 //Tally the count of each digit //in the number, increment by 1 //Start of optimization. Comments are for Number = 1,000 and Last = 8,000. Power = Zeros at the end of number //For 1,000, Power = 3 IF Power 0 //The number ends in 0 00 000 etc Nines = 10^Power-1 //Nines = 10^3 - 1 = 1000 - 1 = 999 IF Number+Nines <= Last //If 1,000+999 < 8,000, add a full set Digits[0-9] += Power*10^(Power-1) //Add 3*10^(3-1) = 300 to digits 0 to 9 Digits[0] -= -Power //Adjust digit 0 (leading zeros formula) Prefix = First digits of Number //For 1000, prefix is 1 CALL TallyDigitsForOneNumber WITH Prefix,Nines //Tally the count of each //digit in prefix, //increment by 999 Number += Nines //Increment the loop counter 999 cycles ENDIF ENDIF //End of optimization ENDFOR SUBROUTINE TallyDigitsForOneNumber PARAMS Number,Count REPEAT Digits [ Number % 10 ] += Count Number = Number / 10 UNTIL Number = 0 For example, for range 786 to 3,021, the counter will be incremented: By 1 from 786 to 790 (5 cycles) By 9 from 790 to 799 (1 cycle) By 1 from 799 to 800 By 99 from 800 to 899 By 1 from 899 to 900 By 99 from 900 to 999 By 1 from 999 to 1000 By 999 from 1000 to 1999 By 1 from 1999 to 2000 By 999 from 2000 to 2999 By 1 from 2999 to 3000 By 1 from 3000 to 3010 (10 cycles) By 9 from 3010 to 3019 (1 cycle) By 1 from 3019 to 3021 (2 cycles) Total: 28 cycles Without optimization: 2,235 cycles Note that this algorithm solves the problem without leading zeros. To use it with leading zeros, I used a hack: If range 700 to 1,000 with leading zeros is needed, use the algorithm for 10,700 to 11,000 and then substract 1,000 - 700 = 300 from the count of digit 1. Benchmark and Source code I tested the original approach, the same approach using %10 and the new solution for some large ranges, with these results: Original 104.78 seconds With %10 83.66 With Powers of Ten 0.07 A screenshot of the benchmark application: If you would like to see the full source code or run the benchmark, use these links: Complete Source code (in Clarion): http://sca.mx/ftp/countdigits.txt Compilable project and win32 exe: http://sca.mx/ftp/countdigits.zip Accepted answer noahlavine solution may be correct, but l just couldn’t follow the pseudo code, I think there are some details missing or not completely explained. Aaronaught solution seems to be correct, but the code is just too complex for my taste. I accepted strainer’s answer, because his line of thought guided me to develop this new solution.

  • Help with force close occurrences in my app

    - by Ken
    This is the last issue with this app. Periodic force close situations. I think something should be on another thread but I'm not sure what. Anyway, I can always count on a freeze on first install. If I wait, eventually (maybe 10 seconds) the app comes around, maybe more. here is an excerpt from logcat--the three lines occur after full layout is displayed and I attempt to touch a [game] 'peg' which should spawn a sprite, but the freeze occurs there. Can anybody tell what the issue might be?: I/System.out( 279): TouchDown (17.0,106.0) I/System.out( 279): checking (17,106 I/System.out( 279): hit for bounds Rect(3, 98 - 32, 130) [FREEZE BEGINS] W/webcore ( 279): Can't get the viewWidth after the first layout W/WindowManager( 60): Key dispatching timed out sending to com.live.brainbuilderfree/com.live.brainbuilderfree.BrainBuilderFree W/WindowManager( 60): Previous dispatch state: null W/WindowManager( 60): Current dispatch state: {{null to Window{43fd87a0 com.live.brainbuilderfree/com.live.brainbuilderfree.BrainBuilderFree paused=false} @ 1295232880017 lw=Window{43fd87a0 com.live.brainbuilderfree/com.live.brainbuilderfree.BrainBuilderFree paused=false} lb=android.os.BinderProxy@440523b8 fin=false gfw=true ed=true tts=0 wf=false fp=false mcf=Window{43fd87a0 com.live.brainbuilderfree/com.live.brainbuilderfree.BrainBuilderFree paused=false}}} I/Process ( 60): Sending signal.

  • luntbuild + maven + findbugs = OutOfMemoryException

    - by Johannes
    Hi, I've been trying to get Luntbuild to generate and publish a project site for our project including a Findbugs report. All other reports (Cobertura, Surefire, JavaDoc, Dashboard) work fine, but Findbugs bails out with an OutOfMemoryException. Excluding findbugs from report generation fixes the build --- although obviously without a Findbugs report. The funny thing is that I first encountered this problem locally and solved it by setting MAVEN_OPTS=-Xmx512m. This does not seem to be enough in Luntbuild, however: setting that exact same option as an environment variable of my builder doesn't make a difference. I've found a couple of posts on the 'net stating you should also add -XX:MaxPermSize=512m to MAVEN_OPTS and/or pass -Dmaven.findbugs.jvmargs=-Xmx512m to mvn.bat. None of these (or their combination) seem to help though so any hints would be greatly appreciated! Cheers, Johannes Relevant information: Luntbuild is 1.5.6, Maven is 2.1.0, findbugs-maven-plugin is 2.0.1.

  • "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

  • Programs won't write to a file, and I do not know if it is reading it

    - by user320950
    This program is supposed to read files and write them. I took the file open checks out because they kept causing errors. The problem is that the files open like they are supposed to and the names are correct but nothing is on any of the text screens. Do you know what is wrong? #include<iostream> #include<fstream> #include<cstdlib> #include<iomanip> using namespace std; int main() { ifstream in_stream; // reads itemlist.txt ofstream out_stream1; // writes in items.txt ifstream in_stream2; // reads pricelist.txt ofstream out_stream3;// writes in plist.txt ifstream in_stream4;// read recipt.txt ofstream out_stream5;// write display.txt float price=' ',curr_total=0.0; int itemnum=' ', wrong=0; char next; in_stream.open("ITEMLIST.txt", ios::in); // list of avaliable items out_stream1.open("listWititems.txt", ios::out); // list of avaliable items in_stream2.open("PRICELIST.txt", ios::in); out_stream3.open("listWitdollars.txt", ios::out); in_stream4.open("display.txt", ios::in); out_stream5.open("showitems.txt", ios::out); in_stream.close(); // closing files. out_stream1.close(); in_stream2.close(); out_stream3.close(); in_stream4.close(); out_stream5.close(); system("pause"); in_stream.setf(ios::fixed); while(in_stream.eof()) { in_stream >> itemnum; cin.clear(); cin >> next; } out_stream1.setf(ios::fixed); while (out_stream1.eof()) { out_stream1 << itemnum; cin.clear(); cin >> next; } in_stream2.setf(ios::fixed); in_stream2.setf(ios::showpoint); in_stream2.precision(2); while((price== (price*1.00)) && (itemnum == (itemnum*1))) { while (in_stream2 >> itemnum >> price) // gets itemnum and price { while (in_stream2.eof()) // reads file to end of file { in_stream2 >> itemnum; in_stream2 >> price; price++; curr_total= price++; in_stream2 >> curr_total; cin.clear(); // allows more reading cin >> next; } } } out_stream3.setf(ios::fixed); out_stream3.setf(ios::showpoint); out_stream3.precision(2); while((price== (price*1.00)) && (itemnum == (itemnum*1))) { while (out_stream3 << itemnum << price) { while (out_stream3.eof()) // reads file to end of file { out_stream3 << itemnum; out_stream3 << price; price++; curr_total= price++; out_stream3 << curr_total; cin.clear(); // allows more reading cin >> next; } return itemnum, price; } } in_stream4.setf(ios::fixed); in_stream4.setf(ios::showpoint); in_stream4.precision(2); while ( in_stream4.eof()) { in_stream4 >> itemnum >> price >> curr_total; cin.clear(); cin >> next; } out_stream5.setf(ios::fixed); out_stream5.setf(ios::showpoint); out_stream5.precision(2); out_stream5 <<setw(5)<< " itemnum " <<setw(5)<<" price "<<setw(5)<<" curr_total " <<endl; // sends items and prices to receipt.txt out_stream5 << setw(5) << itemnum << setw(5) <<price << setw(5)<< curr_total; // sends items and prices to receipt.txt out_stream5 << " You have a total of " << wrong++ << " errors " << endl; }

  • Accessing PerSession service simultaneously in WCF using C#

    - by krishna555
    1.) I have a main method Processing, which takes string as an arguments and that string contains some x number of tasks. 2.) I have another method Status, which keeps track of first method by using two variables TotalTests and CurrentTest. which will be modified every time with in a loop in first method(Processing). 3.) When more than one client makes a call parallely to my web service to call the Processing method by passing a string, which has different tasks will take more time to process. so in the mean while clients will be using a second thread to call the Status method in the webservice to get the status of the first method. 4.) when point number 3 is being done all the clients are supposed to get the variables(TotalTests,CurrentTest) parallely with out being mixed up with other client requests. 5.) The code that i have provided below is getting mixed up variables results for all the clients when i make them as static. If i remove static for the variables then clients are just getting all 0's for these 2 variables and i am unable to fix it. Please take a look at the below code.

  • NSStream sockets missing data

    - by Chris T.
    I am trying to pull some sample data from FreeDB as a proof of concept, but I am having a tough time retrieving all of the data off the incoming stream (I am only getting the last bits for the final query listed here (if handshakeCode = 3) I think this may be something with the threading on the main runloop, but I am not sure. Odd thing is when the buffer size is larger than 1-2 bytes (which works as expected), I seem to be losing access to the data programmatically (the totalOutput variable on the first set of data is incomplete). I set up a packet capture, and it looks like those 1024 bytes are coming across the wire, but the app just isn't working with it. It looks like the next event is coming through and basically taking over. I tried using an NSLock to no avail as well. If I drop the buffer size down to 1 or 2, things seem to be reading just fine. This is probably obvious to someone who does this all the time, but this is my first foray into this with something I am familiar with, technology wise in other languages / platforms. The following code will show you what is happening. Run with the buffer set to 1024, and you will see a short final string, but once you set it to 1, you will see the amount of data I was expecting (I was even expecting it to be split, so that's not a big worry) #import <Foundation/Foundation.h> #import <Cocoa/Cocoa.h> //STACK OVERFLOW CODE: @interface stackoverflow : NSObject <NSStreamDelegate> { NSInputStream *iStream; NSOutputStream *oStream; int handshakeCode; NSString *selectedDiscId; NSString *selectedGenre; } -(void)getMatchesFromFreeDB; -(void)sendToOutputStream:(NSString*)command; @end @implementation stackoverflow -(void)getMatchesFromFreeDB { NSHost *host = [NSHost hostWithName:@"freedb.freedb.org"]; [NSStream getStreamsToHost:host port:8880 inputStream:&iStream outputStream:&oStream]; [iStream retain]; [oStream retain]; [iStream setDelegate:self]; [oStream setDelegate:self]; [iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [oStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [iStream open]; [oStream open]; handshakeCode = 0; //not done any processing } -(void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode { switch(eventCode) { case NSStreamEventOpenCompleted: { NSLog(@"Stream open completed"); break; } case NSStreamEventHasBytesAvailable: { NSLog(@"Stream has bytes available"); if (aStream == iStream) { NSMutableString *totalOutput = [NSMutableString stringWithString:@""]; //read data uint8_t buffer[1024]; int len; while ([iStream hasBytesAvailable]) { len = [iStream read:buffer maxLength:sizeof(buffer)]; if (len 0) { NSString *output = [[NSString alloc] initWithBytes:buffer length:len encoding:NSUTF8StringEncoding]; //this could have also been put into an NSData object if (nil != output) { //append to the total output [totalOutput appendString:output]; } } } NSLog(@"OUTPUT , %i:\n\n%@", [totalOutput lengthOfBytesUsingEncoding:NSUTF8StringEncoding], totalOutput); NSArray *outputComponents = [totalOutput componentsSeparatedByString:@" "]; //Attempt to get handshake code, since we haven't done it yet: if (handshakeCode == 1) { //we are just getting the sign-on banner: //let's move on: handshakeCode = 2; } else if (handshakeCode == 2) { handshakeCode = [[outputComponents objectAtIndex:0] intValue]; if (handshakeCode == 200) { NSLog(@"---Handshake OK %i", handshakeCode); NSMutableString *query = [NSMutableString stringWithString:@"cddb query f3114b11 17 225 19915 36489 54850 69425 87025 103948 123242 136075 152817 178335 192850 211677 235104 262090 284882 308658 4430\n"]; handshakeCode = 3; [self sendToOutputStream:query]; } } else if (handshakeCode == 3) { //now, we are reading out the matches: if ([[outputComponents objectAtIndex:0] intValue] == 200) //found exact match: { NSLog(@"Found exact match"); selectedGenre = [outputComponents objectAtIndex:1] ; selectedDiscId = [outputComponents objectAtIndex:2]; if (selectedGenre && selectedDiscId) { //send off the request to get the entry: NSString *query = [NSString stringWithFormat:@"cddb read %@ %@\n", selectedGenre, selectedDiscId]; [self sendToOutputStream:query]; handshakeCode = 4; } } } } break; } case NSStreamEventEndEncountered: { NSLog(@"Stream event end encountered"); break; } case NSStreamEventErrorOccurred: { NSLog(@"Stream error occurred"); break; } case NSStreamEventHasSpaceAvailable: { NSLog(@"Stream has space available"); if (aStream == oStream) { if (handshakeCode == 0) { handshakeCode = 1; [self sendToOutputStream:@"cddb hello stackoverflow localhost.localdomain test .01BETA\n"]; } } break; } } } -(void)sendToOutputStream:(NSString*)command { const uint8_t *rawCommand = (const uint8_t *)[command UTF8String]; [oStream write:rawCommand maxLength:strlen(rawCommand)]; NSLog(@"Sent command: %@",command); } @end int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; stackoverflow *test = [[stackoverflow alloc] init]; [test getMatchesFromFreeDB]; NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; [runLoop run]; [pool drain]; return 0; } Any help is much appreciated!

  • Son of Suckerfish ie6 problem - right-most dropdown menu also appearing on left side of screen

    - by Kevin Burke
    I'm interning for an NGO in India and trying to fix their website, including updating their menu so it's not the last item on the page to load, and it's centered on the screen. Everything works well enough but when I try out my new menu in IE6, I get this weird error where the content below the menu is padded an extra 30px or so and the material in the right-most drop down appears on the far left of the screen, always visible. When I drop down the rightmost link ("Publications") the content appears both in the correct location and in the same spot on the far left of the screen, and changes color when I hover as well. It's tough to describe, so it would probably be best if you took a look: visit http://sevamandir.org/a30/index.htm in your Internet Explorer 6 browser to see for yourself. I really appreciate your help. Also I'm using a 1000px wide monitor, if there's more hijinks going on outside that space I'd like to know about that too. Here's the relevant code: in the html head: <script> sfHover = function() { var sfEls = document.getElementById("nav").getElementsByTagName("LI"); for (var i=0; i<sfEls.length; i++) { sfEls[i].onmouseover=function() { this.className+=" sfhover"; } sfEls[i].onmouseout=function() { this.className=this.className.replace(new RegExp(" sfhover\\b"), ""); } } } if (window.attachEvent) window.attachEvent("onload", sfHover); </script> text surrounding the menu - the menu is simply <ul id="nav"><li></li></ul> etc. <!--begin catchphrase--> <div style="float:left; height:27px; width:520px; margin:0px; font:16px Arial, Helvetica, sans-serif; font-weight:bold; color:#769841;"> Transforming lives through democratic &amp; participatory development </div> <?php include("menu.php"); ?> </div><!-- end header --> <!--begin main text div--> <div id="maincontent"> Relevant menu CSS: #nav, #nav ul { font:bold 11px Verdana, sans-serif; float: left; width: 980px; list-style: none; line-height: 1; background: white; font-weight: bold; padding: 0; border: solid #769841; border-width: 0; margin: 0 0 1em 0; } #nav a { display: block; width: 140px; /*this is the total width of the upper menu*/ w\idth: 120px; /*this is the width less horizontal padding */ padding: 5px 10px 5px 10px; /*horiz padding is the 2nd & 4th items here - goes Top Right Bottom Left */ color: #ffffff; background:#b6791e; text-decoration: none; } #nav a.daddy { background: url(rightarrow2.gif) center right no-repeat; } #nav li { float: left; padding: 0; width: 140px; /*this needs to be updated to match top #nav a */ background:#b6791e; } #nav li:hover, #nav li a:hover, #nav li:hover a { background:#769841; } #nav li:hover li a { background:#ffffff; color:#769841; } #nav li ul { position: absolute; left: -999em; height: auto; width: 14.4em; w\idth: 13.9em; font-weight: bold; border-width: 0.25em; /*green border around dropdown menu*/ margin: 0; } #nav li ul a { background:#ffffff; color:#769841; } #nav li li { padding-right: 1em; width: 13em; background:#ffffff; } #nav li ul a { width: 13em; w\idth: 9em; } #nav li ul ul { margin: -1.75em 0 0 14em; } #nav li:hover ul ul, #nav li:hover ul ul ul, #nav li.sfhover ul ul, #nav li.sfhover ul ul ul { left: -999em; } #nav li:hover ul, #nav li li:hover ul, #nav li li li:hover ul, #nav li.sfhover ul, #nav li li.sfhover ul, #nav li li li.sfhover ul { left: auto; } #nav li:hover, #nav li.sfhover, { background: #769841; color:#ffe400; } #nav li a:hover, #nav li li a:hover, #nav li:hover li:hover, #nav li.sfhover a:hover { background: #769841; color:#ffe400; }

  • Possible memory leak problem

    - by MaiTiano
    I write two pieces of c programs like following, during memcheck process using Valgrind, a lot of mem leak information is given. int GetMemory(int framewidth, int frameheight, int SR/*, int blocksize*//*,int ALL_REF_NUM*/) { //int i,j; int memory_size = 0; //int refnum = ALL_REF_NUM; int input_search_range = SR; memory_size += get_mem2D(&curFrameY, frameheight, framewidth); memory_size += get_mem2D(&curFrameU, frameheight>>1, framewidth>>1); memory_size += get_mem2D(&curFrameV, frameheight>>1, framewidth>>1); memory_size += get_mem3D(&prevFrameY, refnum, frameheight, framewidth);// to allocate reference frame buffer accoding to the reference frame number memory_size += get_mem3D(&prevFrameU, refnum, frameheight>>1, framewidth>>1); memory_size += get_mem3D(&prevFrameV, refnum, frameheight>>1, framewidth>>1); memory_size += get_mem2D(&mpFrameY, frameheight, framewidth); memory_size += get_mem2D(&mpFrameU, frameheight>>1, framewidth>>1); memory_size += get_mem2D(&mpFrameV, frameheight>>1, framewidth>>1); memory_size += get_mem2D(&searchwindow, input_search_range*2 + blocksize, input_search_range*2 + blocksize);// to allocate search window according to the searchrange /*memory_size +=*/ get_mem1D(/*&SAD_cost, height, width*/); // memory_size += get_mem2D(&searchwindow, 80, 80);// if searchrange is 32, then only 32+1+32+15 pixels is needed in each row and col, therefore the range of // search window is enough to be set to 80 ! memory_size += get_mem2Dint(&all_mv, height/blocksize, width/blocksize); return 0; } void FreeMemory(int refno) { free_mem2D(curFrameY); free_mem2D(curFrameU); free_mem2D(curFrameV); free_mem3D(prevFrameY,refno); free_mem3D(prevFrameU,refno); free_mem3D(prevFrameV,refno); free_mem2D(mpFrameY); free_mem2D(mpFrameU); free_mem2D(mpFrameV); free_mem2D(searchwindow); free_mem1D(); free_mem2Dint(all_mv); } void free_mem1D() { free(SAD_cost); } Now I hope to make sure where are the possible problems in my program? Here I may post some valgrind information to let you know about the actual error information. ==29105== by 0x804A906: main (me_search.c:1480) ==29105== ==29105== ==29105== HEAP SUMMARY: ==29105== in use at exit: 124,088 bytes in 18 blocks ==29105== total heap usage: 37 allocs, 21 frees, 749,276 bytes allocated ==29105== ==29105== 272 bytes in 1 blocks are still reachable in loss record 1 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804885E: GetMemory (me_search.c:117) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 352 bytes in 1 blocks are still reachable in loss record 2 of 18 ==29105== at 0x4024F20: malloc (vg_replace_malloc.c:236) ==29105== by 0x409537E: __fopen_internal (iofopen.c:76) ==29105== by 0x409544B: fopen@@GLIBC_2.1 (iofopen.c:107) ==29105== by 0x804A660: main (me_search.c:1439) ==29105== ==29105== 584 bytes in 1 blocks are still reachable in loss record 3 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x8048724: GetMemory (me_search.c:106) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are still reachable in loss record 4 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x8048747: GetMemory (me_search.c:107) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are still reachable in loss record 5 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x8048809: GetMemory (me_search.c:114) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are still reachable in loss record 6 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804882C: GetMemory (me_search.c:115) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are definitely lost in loss record 7 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804A4F8: get_mem3D (me_search.c:1393) ==29105== by 0x804879B: GetMemory (me_search.c:110) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 584 bytes in 1 blocks are definitely lost in loss record 8 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804A4F8: get_mem3D (me_search.c:1393) ==29105== by 0x80487C9: GetMemory (me_search.c:111) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 1,168 bytes in 1 blocks are still reachable in loss record 9 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x8048701: GetMemory (me_search.c:105) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 1,168 bytes in 1 blocks are still reachable in loss record 10 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x80487E6: GetMemory (me_search.c:113) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 1,168 bytes in 1 blocks are definitely lost in loss record 11 of 18 ==29105== at 0x402425F: calloc (vg_replace_malloc.c:467) ==29105== by 0x804A296: get_mem2D (me_search.c:1315) ==29105== by 0x804A4F8: get_mem3D (me_search.c:1393) ==29105== by 0x804876D: GetMemory (me_search.c:109) ==29105== by 0x804A757: main (me_search.c:1456) ==29105== ==29105== 6,336 bytes in 1 blocks are definitely lost in loss record 12 of 18 ==29105== at 0x4024F20: malloc (vg_replace_malloc.c:236) ==29105== by 0x804A25C: get_mem1D (me_search.c:1295) ==29105== by 0x8048866: GetMemory (me_search.c:119) ==29105== by 0x804A757: main (me_search.c:1456)

  • PHP mtChart (new pChart): how do i control the angle of x-axis labels?

    - by gsquare567
    i am trying to graph the results of a survey, where the question is multiple choice. eg. How would you describe this website? format: option | number of times selected | percentage of users who selected that option Informative 1 50% All of the above 1 50% Interesting 0 0% Intelligent 0 0% Cool 0 0% Incredible 0 0% Sleek 0 0% Amazing the graph is a bar graph, where each bar represents one of those options, and the height of the bar depends on the number of times selected. however, the labels are slanted at a 45 degree angle and are barely readable! here is my code: <?php require_once ("includes/common.php"); require_once ("graph/mtChart.min.php"); // type must be specified $type = $_GET['type']; if($type == "surveys_report_MC_or_CB") { // PARAMS $surveyID = $_GET['surveyID']; $questionID = $_GET['questionID']; // END PARAMS $question = SurveyQuestions::getSingle($questionID); $answers = SurveyAnswers::getAll($questionID); $options = SurveyQuestionOptions::getAll($question[SurveyQuestions::surveyQuestionID]); $others = SurveyAnswers::setOptionCounts($options, $answers); $printedOthers = false; // set graph $values = array(); $axisLabels = array(); foreach($options as $option) { $values[$option[SurveyQuestionOptions::optionText]] = $option['count']; $axisLabels[] = $option[SurveyQuestionOptions::optionText]; } $graphs = array(); $graphs[0] = $values; $xName = "Option"; $yName = "Number of Times Selected"; $graphTitle = $question[SurveyQuestions::question]; $series = array("Total"); $showLegend = false; $tall = false; } drawGraph($graphs, $axisLabels, $xName, $yName, $graphTitle, $series, $showLegend, $tall); function drawGraph($graphs, $axisLabels, $xName, $yName, $graphTitle, $series, $showLegend, $tall) { $Graph = ($tall) ? new mtChart(575,375) : new mtChart(575,275); // Dataset definition $avg = 0; $i = 0; foreach ($graphs as $key => $value) { $Graph->AddPoint($value,"series" . $key); $Graph->SetSerieName($series[$key],"series" . $key); // Get average $avg += array_sum($value); $size = sizeof($value); $i += $size; // Calculate x-axis tick interval $step = ceil($size / 25); } $Graph->AddPoint($axisLabels,"XLabel"); $Graph->AddAllSeries(); $Graph->RemoveSerie("XLabel"); $Graph->SetAbsciseLabelSerie("XLabel"); $Graph->SetXAxisName($xName); $Graph->SetYAxisName($yName); // Get from cache if it exists $Graph->enableCaching(NULL, 'graph/cache/'); $Graph->GetFromCache(); // Initialize the graph $Graph->setInterval($step); $Graph->setFontProperties("graph/tahoma.ttf",8); ($showLegend) ? $Graph->setGraphArea(45,30,475,200) : $Graph->setGraphArea(75,30,505,200); $Graph->drawGraphArea(255,255,255,TRUE); $Graph->drawScale(SCALE_START0,100,100,100,TRUE,55,1,TRUE); $Graph->drawGrid(4,TRUE,230,230,230,50); // Draw the 0 line $Graph->setFontProperties("graph/tahoma.ttf",6); $Graph->drawTreshold(0,143,55,72,TRUE,TRUE); // Draw the bar graph $Graph->drawBarGraph(); // Draw average line $Graph->drawTreshold($avg/$i, 0, 0, 0, FALSE, FALSE, 5); // Finish the graph $Graph->setFontProperties("graph/tahoma.ttf",8); if ($showLegend) { $Graph->drawLegend(482,30,255,255,255,255,255,255,100,100,100); } $Graph->setFontProperties("graph/tahoma.ttf",10); $Graph->drawTitle(0,22,$graphTitle,100,100,100,555); // Draw Graph $Graph->Stroke(); } and here is where i use it on the page: <div class="graph_container"> <img src="drawGraph.php?type=surveys_report_MC_or_CB&surveyID=<?php echo $survey[Surveys::surveyID] ?>&questionID=<?php echo $question[SurveyQuestions::surveyQuestionID] ?>" /> is there a setting i can apply to the graph which will make the text look nicer, or at least let me set the angle to 90 degrees so people can read it if they cock their head to the left? thanks! btw, mtchart is located here: http://code.google.com/p/mtchart/ and pchart (the original, which has mainly the same code) is here: http://pchart.sourceforge.net/documentation.php

  • Very simple, terse and easy GUI programming “frameworks”

    - by jetxee
    Please list GUI programming libraries, toolkits, frameworks which allow to write GUI apps quickly. I mean in such a way, that GUI is described entirely in a human-readable (and human-writable) plain text file (code) code is terse (1 or 2 lines of code per widget/event pair), suitable for scripting structure and operation of the GUI is evident from the code (nesting of widgets and flow of events) details about how to build the GUI are hidden (things like mainloop, attaching event listeners, etc.) auto-layouts are supported (vboxes, hboxes, etc.) As answers suggest, this may be defined as declarative GUI programming, but it is not necessarily such. Any approach is OK if it works, is easy to use and terse. There are some GUI libraries/toolkits like this. They are listed below. Please extend the list if you see a qualifying toolkit missing. Indicate if the project is crossplatform, mature, active, and give an example if possible. Please use this wiki to discuss only Open Source projects. This is the list so far (in alphabetical order): Fudgets Fudgets is a Haskell library. Platform: Unix. Status: Experimental, but still maintained. An example: import Fudgets main = fudlogue (shellF "Hello" (labelF "Hello, world!" >+< quitButtonF)) GNUstep Renaissance Renaissance allows to describe GUI in simple XML. Platforms: OSX/GNUstep. Status: part of GNUstep. An example below: <window title="Example"> <vbox> <label font="big"> Click the button below to quit the application </label> <button title="Quit" action="terminate:"/> </vbox> </window> HTML HTML-based GUI (HTML + JS). Crossplatform, mature. Can be used entirely on the client side. Looking for a nice “helloworld” example. JavaFX JavaFX is usable for standalone (desktop) apps as well as for web applications. Not completely crossplatform, not yet completely open source. Status: 1.0 release. An example: Frame { content: Button { text: "Press Me" action: operation() { System.out.println("You pressed me"); } } visible: true } Screenshot is needed. Phooey Phooey is another Haskell library. Crossplatform (wxWidgets), HTML+JS backend planned. Mature and active. An example (a little more than a helloworld): ui1 :: UI () ui1 = title "Shopping List" $ do a <- title "apples" $ islider (0,10) 3 b <- title "bananas" $ islider (0,10) 7 title "total" $ showDisplay (liftA2 (+) a b) PythonCard PythonCard describes GUI in a Python dictionary. Crossplatform (wxWidgets). Some apps use it, but the project seems stalled. There is an active fork. I skip PythonCard example because it is too verbose for the contest. Shoes Shoes for Ruby. Platforms: Win/OSX/GTK+. Status: Young but active. A minimal app looks like this: Shoes.app { @push = button "Push me" @note = para "Nothing pushed so far" @push.click { @note.replace "Aha! Click!" } } Tcl/Tk Tcl/Tk. Crossplatform (its own widget set). Mature (probably even dated) and active. An example: #!/usr/bin/env wish button .hello -text "Hello, World!" -command { exit } pack .hello tkwait window . tekUI tekUI for Lua (and C). Platforms: X11, DirectFB. Status: Alpha (usable, but API still evolves). An example: #/usr/bin/env lua ui = require "tek.ui" ui.Application:new { Children = { ui.Window:new { Title = "Hello", Children = { ui.Text:new { Text = "_Hello, World!", Style = "button", Mode = "button", }, }, }, }, }:run() Treethon Treethon for Python. It describes GUI in a YAML file (Python in a YAML tree). Platform: GTK+. Status: work in proress. A simple app looks like this: _import: gtk view: gtk.Window() add: - view: gtk.Button('Hello World') on clicked: print view.get_label() Yet unnamed Python library by Richard Jones: This one is not released yet. The idea is to use Python context managers (with keyword) to structure GUI code. See Richard Jones' blog for details. with gui.vertical: text = gui.label('hello!') items = gui.selection(['one', 'two', 'three']) with gui.button('click me!'): def on_click(): text.value = items.value text.foreground = red XUL XUL + Javascript may be used to create stand-alone desktop apps with XULRunner as well as Mozilla extensions. Mature, open source, crossplatform. <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <window id="main" title="My App" width="300" height="300" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <caption label="Hello World"/> </window> Thank your for contributions!

  • Can't get my head arround background workers in c#

    - by Connel
    I have wrote an application that syncs two folders together. The problem with the program is that it stops responding whilst copying files. A quick search of stack-overflow told me I need to use something called a background worker. I have read a few pages on the net about this but find it really hard to understand as I'm pretty new to programming. Below is the code for my application - how can I simply put all of the File.Copy(....) commands into their own background worker (if that's even how it works)? Below is the code for the button click event that runs the sub procedure and the sub procedure I wish to use a background worker on all the File.Copy lines. Button event: protected virtual void OnBtnSyncClicked (object sender, System.EventArgs e) { //sets running boolean to true booRunning=true; //sets progress bar to 0 prgProgressBar.Fraction = 0; //resets values used by progressbar dblCurrentStatus = 0; dblFolderSize = 0; //tests if user has entered the same folder for both target and destination if (fchDestination.CurrentFolder == fchTarget.CurrentFolder) { //creates message box MessageDialog msdSame = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync two folders that are the same"); //sets message box title msdSame.Title="Error"; //sets respone type ResponseType response = (ResponseType) msdSame.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdSame.Destroy(); } return; } //tests if user has entered a target folder that is an extension of the destination folder // or if user has entered a desatination folder that is an extension of the target folder if (fchTarget.CurrentFolder.StartsWith(fchDestination.CurrentFolder) || fchDestination.CurrentFolder.StartsWith(fchTarget.CurrentFolder)) { //creates message box MessageDialog msdContains = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync a folder with one of its parent folders"); //sets message box title msdContains.Title="Error"; //sets respone type and runs message box ResponseType response = (ResponseType) msdContains.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdContains.Destroy(); } return; } //gets folder size of target folder FileSizeOfTarget(fchTarget.CurrentFolder); //gets folder size of destination folder FileSizeOfDestination(fchDestination.CurrentFolder); //runs SyncTarget procedure SyncTarget(fchTarget.CurrentFolder); //runs SyncDestination procedure SyncDestination(fchDestination.CurrentFolder); //informs user process is complete prgProgressBar.Text = "Finished"; //sets running bool to false booRunning = false; } Sync sub-procedure: protected void SyncTarget (string strCurrentDirectory) { //string array of all the directories in directory string[] staAllDirectories = Directory.GetDirectories(strCurrentDirectory);

//tests if file does not exist in destination folder if (!File.Exists(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName)) { //if file does not exist copy it to destination folder, the true below means overwrite if file already exists File.Copy (strFile, fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName, true); } //tests if file does exist in destination folder if (File.Exists(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName)) { //long (number) that contains date of last write time of target file long lngTargetFileDate = File.GetLastWriteTime(strFile).ToFileTime(); //long (number) that contains date of last write time of destination file long lngDestinationFileDate = File.GetLastWriteTime(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName).ToFileTime(); //tests if target file is newer than destination file if (lngTargetFileDate > lngDestinationFileDate) { //if it is newer then copy file from target folder to destination folder File.Copy (strFile, fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName, true); } } //gets current file size FileInfo FileSize = new FileInfo(strFile); //sets file's filesize to dblCurrentStatus and adds it to current total of files dblCurrentStatus = dblCurrentStatus + FileSize.Length; double dblPercentage = dblCurrentStatus/dblFolderSize; prgProgressBar.Fraction = dblPercentage; } //loop over each folder in target folder foreach (string strDirectory in staAllDirectories) { //string containing directories inside target folder but not any higher directories string strDirectoryInsideTarget = strDirectory.Substring(fchTarget.CurrentFolder.Length);

} //run sync on all files in directory SyncTarget(strDirectory); } } Any help will be greatly appreciated as after this the program will pretty much be finished :D

A quick search of stack-overflow told me I need to use something called a background worker. I have read a few pages on the net about this but find it really hard to understand as I'm pretty new to programming. Below is the code for my application - how can I simply put all of the File.Copy(....) commands into their own background worker (if that's even how it works)? Below is the code for the button click event that runs the sub procedure and the sub procedure I wish to use a background worker on all the File.Copy lines. Button event: protected virtual void OnBtnSyncClicked (object sender, System.EventArgs e) { //sets running boolean to true booRunning=true; //sets progress bar to 0 prgProgressBar.Fraction = 0; //resets values used by progressbar dblCurrentStatus = 0; dblFolderSize = 0; //tests if user has entered the same folder for both target and destination if (fchDestination.CurrentFolder == fchTarget.CurrentFolder) { //creates message box MessageDialog msdSame = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync two folders that are the same"); //sets message box title msdSame.Title="Error"; //sets respone type ResponseType response = (ResponseType) msdSame.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdSame.Destroy(); } return; } //tests if user has entered a target folder that is an extension of the destination folder // or if user has entered a desatination folder that is an extension of the target folder if (fchTarget.CurrentFolder.StartsWith(fchDestination.CurrentFolder) || fchDestination.CurrentFolder.StartsWith(fchTarget.CurrentFolder)) { //creates message box MessageDialog msdContains = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync a folder with one of its parent folders"); //sets message box title msdContains.Title="Error"; //sets respone type and runs message box ResponseType response = (ResponseType) msdContains.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdContains.Destroy(); } return; } //gets folder size of target folder FileSizeOfTarget(fchTarget.CurrentFolder); //gets folder size of destination folder FileSizeOfDestination(fchDestination.CurrentFolder); //runs SyncTarget procedure SyncTarget(fchTarget.CurrentFolder); //runs SyncDestination procedure SyncDestination(fchDestination.CurrentFolder); //informs user process is complete prgProgressBar.Text = "Finished"; //sets running bool to false booRunning = false; } Sync sub-procedure: protected void SyncTarget (string strCurrentDirectory) { //string array of all the directories in directory string[] staAllDirectories = Directory.GetDirectories(strCurrentDirectory); //string array of all the files in directory string[] staAllFiles = Directory.GetFiles(strCurrentDirectory); //loop over each file in directory foreach (string strFile in staAllFiles) { //string of just the file's name and not its path string strFileName = System.IO.Path.GetFileName(strFile); //string containing directory in target folder string strDirectoryInsideTarget = System.IO.Path.GetDirectoryName(strFile).Substring(fchTarget.CurrentFolder.Length); //inform user as to what file is being copied prgProgressBar.Text="Syncing " + strFile; //tests if file does not exist in destination folder if (!File.Exists(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName)) { //if file does not exist copy it to destination folder, the true below means overwrite if file already exists File.Copy (strFile, fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName, true); } //tests if file does exist in destination folder if (File.Exists(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName)) { //long (number) that contains date of last write time of target file long lngTargetFileDate = File.GetLastWriteTime(strFile).ToFileTime(); //long (number) that contains date of last write time of destination file long lngDestinationFileDate = File.GetLastWriteTime(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName).ToFileTime(); //tests if target file is newer than destination file if (lngTargetFileDate > lngDestinationFileDate) { //if it is newer then copy file from target folder to destination folder File.Copy (strFile, fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName, true); } } //gets current file size FileInfo FileSize = new FileInfo(strFile); //sets file's filesize to dblCurrentStatus and adds it to current total of files dblCurrentStatus = dblCurrentStatus + FileSize.Length; double dblPercentage = dblCurrentStatus/dblFolderSize; prgProgressBar.Fraction = dblPercentage; } //loop over each folder in target folder foreach (string strDirectory in staAllDirectories) { //string containing directories inside target folder but not any higher directories string strDirectoryInsideTarget = strDirectory.Substring(fchTarget.CurrentFolder.Length); //tests if directory does not exist inside destination folder if (!Directory.Exists(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget)) { //it directory does not exisit create it Directory.CreateDirectory(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget); } //run sync on all files in directory SyncTarget(strDirectory); } } Any help will be greatly appreciated as after this the program will pretty much be finished :D

  • jQuery templates - Load another template within a template (composite)

    - by Saxman
    I'm following this post by Dave Ward (http://encosia.com/2010/12/02/jquery-templates-composite-rendering-and-remote-loading/) to load a composite templates for a Blog, where I have a total of 3 small templates (all in one file) for a blog post. In the template file, I have these 3 templates: blogTemplate, where I render the "postTemplate" Inside the "postTemplate", I would like to render another template that displays comments, I called this "commentsTemplate" the "commentsTemplate" Here's the structure of my json data: blog Title Content PostedDate Comments (a collection of comments) CommentContents CommentedBy CommentedDate For now, I was able to render the Post content using the code below: Javascript $(document).ready(function () { $.get('/GetPost', function (data) { $.get('/Content/Templates/_postWithComments.tmpl.htm', function (templates) { $('body').append(templates); $('#blogTemplate').tmpl(data).appendTo('#blogPost'); }); }); }); Templates <!--Blog Container Templates--> <script id="blogTemplate" type="x-jquery-tmpl"> <div class="latestPost"> {{tmpl() '#postTemplate'}} </div> </script> <!--Post Item Container--> <script id="postTemplate" type="x-jquery-tmpl"> <h2> ${Title}</h2> <div class="entryHead"> Posted in <a class="category" rel="#">Design</a> on ${PostedDateString} <a class="comments" rel="#">${NumberOfComments} Comments</a></div> ${Content} <div class="tags"> {{if Tags.length}} <strong>Tags:</strong> {{each(i, tag) Tags}} <a class="tag" href="/blog/tags/{{= tag.Name}}"> {{= tag.Name}}</a> {{/each}} <a class="share" rel="#"><strong>TELL A FRIEND</strong></a> <a class="share twitter" rel="#">Twitter</a> <a class="share facebook" rel="#">Facebook</a> {{/if}} </div> <!-- close .tags --> <!-- end Entry 01 --> {{if Comments.length}} {{each(i, comment) Comments}} {{tmpl() '#commentTemplate'}} {{/each}} {{/if}} <div class="lineHor"> </div> </script> <!--Comment Items Container--> <script id="commentTemplate" type="x-jquery-tmpl"> <h4> Comments</h4> &nbsp; <!-- COMMENT --> <div id="authorComment1"> <div id="gravatar1" class="grid_2"> <!--<img src="images/gravatar.png" alt="" />--> </div> <!-- close #gravatar --> <div id="commentText1"> <span class="replyHead">by<a class="author" rel="#">${= comment.CommentedBy}</a>on today</span> <p> {{= comment.CommentContents}}</p> </div> <!-- close #commentText --> <div id="quote1"> <a class="quote" rel="#"><strong>Quote this Comment</strong></a> </div> <!-- close #quote --> </div> <!-- close #authorComment --> <!-- END COMMENT --> </script> Where I'm having problem is at the {{each(i, comment) Comments}} {{tmpl() '#commentTemplate'}} {{/each}} Update - Example Json data when GetPost method is called { Id: 1, Title: "Test Blog", Content: "This is a test post asdf asdf asdf asdf asdf", PostedDateString: "2010-12-20", - Comments: [ - { Id: 1, PostId: 1, CommentContents: "Test comments # 1, asdf asdf asdf", PostedBy: "User 1", CommentedDate: "2010-12-20" }, - { Id: 2, PostId: 1, CommentContents: "Test comments # 2, ghjk gjjk gjkk", PostedBy: "User 2", CommentedDate: "2010-12-21" } ] } I've tried passing in {{tmpl(comment) ..., {{tmpl(Comments) ..., or leave {{tmpl() ... but none seems to work. I don't know how to iterate over the Comments collection and pass that object into the commentsTemplate. Any suggestions? Thank you very much.

  • PHP: Strange behaviour while calling custom php functions

    - by baltusaj
    I am facing a strange behavior while coding in PHP with Flex. Let me explain the situation: I have two funcions lets say: populateTable() //puts some data in a table made with flex createXML() //creates an xml file which is used by Fusion Charts to create a chart Now, if i call populateTable() alone, the table gets populated with data but if i call it with createXML(), the table doesn't get populated but createXML() does it's work i.e. creates an xml file. Even if i run following code, only xml file gets generated but table remains empty whereas i called populateTable() before createXML(). Any idea what may be going wrong?
