  • random, Graphics point ,searching- algorithm, via dual for loop set

    - by LoneXcoder
    hello and thanks for joining me in my journey to the custom made algorithm for "guess where the pixel is" this for Loop set (over Point.X, Point.Y), is formed in consecutive/linear form: //Original\initial Location Point initPoint = new Point(150, 100); // No' of pixels to search left off X , and above Y int preXsrchDepth, preYsrchDepth; // No' of pixels to search to the right of X, And Above Y int postXsrchDepth, postYsrchDepth; preXsrchDepth = 10; // will start search at 10 pixels to the left from original X preYsrchDepth = 10; // will start search at 10 pixels above the original Y postXsrchDepth = 10; // will stop search at 10 pixels to the right from X postYsrchDepth = 10; // will stop search at 10 pixels below Y int StopXsearch = initPoint.X + postXsrchDepth; //stops X Loop itarations at initial pointX + depth requested to serch right of it int StopYsearch = initPoint.Y + postYsrchDepth; //stops Y Loop itarations at initial pointY + depth requested below original location int CountDownX, CountDownY; // Optional not requierd for loop but will reports the count down how many iterations left (unless break; triggerd ..uppon success) Point SearchFromPoint = Point.Empty; //the point will be used for (int StartX = initPoint.X - preXsrchDepth; StartX < StopXsearch; StartX++) { SearchFromPoint.X = StartX; for (int StartY = initPoint.Y - preYsrchDepth; StartY < StpY; StartY++) { CountDownX = (initPoint.X - StartX); CountDownY=(initPoint.Y - StartY); SearchFromPoint.Y = StartY; if (SearchSuccess) { same = true; AAdToAppLog("Search Report For: " + imgName + "Search Completed Successfully On Try " + CountDownX + ":" + CountDownY); break; } } } <-10 ---- -5--- -1 X +1--- +5---- +10 what i would like to do is try a way of instead is have a little more clever approach <+8---+5-- -8 -5 -- +2 +10 X -2 - -10 -8-- -6 ---1- -3 | +8 | -10 Y +1 -6 | | +9 .... I do know there's a wheel already invented in this field (even a full-trailer truck amount of wheels (: ) but as a new programmer, I really wanted to start of with a simple way and also related to my field of interest in my project. can anybody show an idea of his, he learnt along the way to Professionalism in algorithm /programming having tests to do on few approaches (kind'a random cleverness...) will absolutely make the day and perhaps help some others viewing this page in the future to come it will be much easier for me to understand if you could use as much as possible similar naming to variables i used or implenet your code example ...it will be Greatly appreciated if used with my code sample, unless my metod is a realy flavorless. p.s i think that(atleast as human being) the tricky part is when throwing inconsecutive numbers you loose track of what you didn't yet use, how do u take care of this too . thanks allot in advance looking forward to your participation !

  • Noob Question: Wordpress Looping

    - by dclowd9901
    Can someone give me an essential Wordpress Loop and explain to me what's happening with it? I'd like to put together some templates, but I don't do well with blackboxing. In other words, I'm fully capable of writing my own CMS, but when it comes to using someone else's and its arbitrary rules, I'm completely at a loss, and I just can't get my head around the standard loop Wordpress uses. Thanks for your patient guidance.

  • Gradual memory leak in loop over contents of QTMovie

    - by Benji XVI
    I have a simple foundation tool that exports every frame of a movie as a .tiff file. Here is the relevant code: NSString* movieLoc = [NSString stringWithCString:argv[1]]; QTMovie *sourceMovie = [QTMovie movieWithFile:movieLoc error:nil]; int i=0; while (QTTimeCompare([sourceMovie currentTime], [sourceMovie duration]) != NSOrderedSame) { // save image of movie to disk NSAutoreleasePool *arp = [[NSAutoreleasePool alloc] init]; NSString *filePath = [NSString stringWithFormat:@"/somelocation_%d.tiff", i++]; NSData *currentImageData = [[sourceMovie currentFrameImage] TIFFRepresentation]; [currentImageData writeToFile:filePath atomically:NO]; NSLog(@"%@", filePath); [sourceMovie stepForward]; [arp release]; } [pool drain]; return 0; As you can see, in order to prevent very large memory buildups with the various transparently-autoreleased variables in the loop, we create, and flush, an autoreleasepool with every run through the loop. However, over the course of stepping through a movie, the amount of memory used by the program still gradually increases. Instruments is not detecting any memory leaks per se, but the object trace shows certain General Data blocks to be increasing in size. [Edited out reference to slowdown as it doesn't seem to be as much of a problem as I thought.] Edit: let's knock out some parts of the code inside the loop & see what we find out... Test 1 while (banana) { NSAutoreleasePool *arp = [[NSAutoreleasePool alloc] init]; NSString *filePath = [NSString stringWithFormat:@"/somelocation_%d.tiff", i++]; NSLog(@"%@", filePath); [sourceMovie stepForward]; [arp release]; } Here we simply loop over the whole movie, creating the filename and logging it. Memory characteristics: remains at 15MB usage for the duration. Test 2 while (banana) { NSAutoreleasePool *arp = [[NSAutoreleasePool alloc] init]; NSImage *image = [sourceMovie currentFrameImage]; [sourceMovie stepForward]; [arp release]; } Here we add back in the creation of the NSImage from the current frame. Memory characteristics: gradually increasing memory usage. RSIZE is at 60MB by frame 200; 75MB by f300. Test 3 while (banana) { NSAutoreleasePool *arp = [[NSAutoreleasePool alloc] init]; NSImage *image = [sourceMovie currentFrameImage]; NSData *imageData = [image TIFFRepresentation]; [sourceMovie stepForward]; [arp release]; } We've added back in the creation of an NSData object from the NSImage. Memory characteristics: Memory usage is again increasing: 62MB at f200; 75MB at f300. In other words, largely identical. It looks like a memory leak in the underlying system QTMovie uses to do currentFrameImage, to me.

  • Loop through Json object

    - by Tanmoy
    I have a JSON object like the following var p = { "p1": "value1", "p2": "value2", "p3": "value3" }; Now I want to loop through all p elements (p1,p2,p3...) and get their key and values. How can I do that? I can modify the Json object if necessary . My ultimate goal is to loop through some key value pairs. And if possible I want to avoid using eval.

I have a sound looping, and my animation is only 13 frames long, while the song is like a minute long, so each time the animation loops threw the default "Loop Playback" a new sound audio is played which os overlapping the previous over and over causing a massive echo effect. Whats the best way to loop both of them insync, or atleast copy and paste the animations frames and make it the length of the song?

  • How to organize infinite while loop in mssql ?

    - by alpav
    I want to use infinite WHILE loop in SQL 2005 and use BREAK keyword to exit from it on certain condition. while true does not work, so I have to use while 1=1. Is there a better way to organize infinite loop ? I know that I can use goto, but while 1=1 begin .. end looks better structurally.

  • Shell loops using non-integers?

    - by mary
    I wrote a .sh file to compile and run a few programs for a homework assignment. I have a "for" loop in the script, but it won't work unless I use only integers: #!/bin/bash for (( i=10; i<=100000; i+=100)) do ./hw3_2_2 $i done The variable $i is an input for the program hw3_2_2, and I have non-integer values I'd like to use. How could I loop through running the code with a list of decimal numbers?

  • logging in continouous loop

    - by Mikkel Jans
    What would be a good way to create logs (with python logging module) inside a constant running loop, without producing a large amount of useless log-files? An example would be a loop that constant list a folder, and does some action when it sees a file of a specific type. I want to log that no files were found, or files were found but of a wrong type, without logging that same line constantly for each folder check, as it might run many times a second.

  • I need to know inside of "while(fscanf != EOF){blah}" if the next fscanf is going to return EOF-- be

    - by Rancur3p1c
    I've got some code executing in a while(fscanf != EOF) loop. However, even when fscanf has finished executing, I need to keep running that code until some conditions are met. I mean I guess I could copy/paste the code to outside the while(fscanf) loop, and only use global variables, but that seems messy. Surely someone has encountered something like this before and has a cleaner solution.

  • odd nullreference error at foreach when rendering view

    - by giddy
    This error is so weird I Just can't really figure out what is really wrong! In UserController I have public virtual ActionResult Index() { var usersmdl = from u in RepositoryFactory.GetUserRepo().GetAll() select new UserViewModel { ID = u.ID, UserName = u.Username, UserGroupName = u.UserGroupMain.GroupName, BranchName = u.Branch.BranchName, Password = u.Password, Ace = u.ACE, CIF = u.CIF, PF = u.PF }; if (usersmdl != null) { return View(usersmdl.AsEnumerable()); } return View(); } My view is of type @model IEnumerable<UserViewModel> on the top. This is what happens: Where and what exactly IS null!? I create the users from a fake repository with moq. I also wrote unit tests, which pass, to ensure the right amount of mocked users are returned. Maybe someone can point me in the right direction here? Top of the stack trace is : at lambda_method(Closure , User ) at System.Linq.Enumerable.WhereSelectArrayIterator`2.MoveNext() at ASP.Index_cshtml.Execute() Is it something to do with linq here? Tell me If I should include the full stack trace.

  • sending +-200 emails using php mail() function in a loop

    - by Glenn
    Note: It is worth noting that the mail() function is not suitable for larger volumes of email in a loop. This function opens and closes an SMTP socket for each email, which is not very efficient. Source: PHP manual What are larger volumes? A 100 or a 1000?? Can I safely make it loop 200 times without much problems? (I can't install pear)

  • Breaking out of a nested loop

    - by dotnetdev
    If I have a for loop which is nested within another, how can I efficiently come out of both loops (inner and outer) in the quickest possible way? I don't want to have to use a boolean and then have to say go to another method, but rather just to execute the first line of code after the outer loop. What is a quick and nice way of going about this? Thanks

  • Accordion "growing out" from its container - in IE7/8

    - by Richard Knop
    I think this problem is best explained by images. This is how my accordion looks: When you click on the small plus/minus icons the slides under each chapter will expand/collapse. However when the content in the accordion grows too tall, it grows out from its container. So if I click on more plus icons the accordion will look like this (not pretty): As you can see, the container is not growing taller together with the accordion and it does not look good. This problem only occurs in IE7 and IE8. It works in Firefox and Chrome. The HTML looks like this (simplified): <div id="content"> <div class="box2 rounded-corners"> <div class="chapters"> <h3><a href="/clientarea/view/archived-course/teid/133">Obsah</a></h3> <div id="accordion"> <ul> ... // accordion content - too long ... // accordion content - too long </ul> <div class="clear">&nbsp;</div> </div> <div class="clear">&nbsp;</div> </div> <div class="training-body"> ... // content to the right of the accordion </div> </div> </div> The CSS, again siplified: html, body { height: 100%; width: 100%; overflow: auto; } #content { background: white url('/images/background_middle.png') left top repeat-x; padding: 13px; min-height: 40em; height: auto !important; height: 40em; } /* this is the div with rounded corners */ #content .box2 { background: white; padding: 0 15px 15px; border: 1px solid #C5E3F8; position: relative; } /* left sidebar 98 #content div.chapters { float: left; width: 224px; } /* orange heading "OBSAH" */ #content div.chapters h3 { color: #ff6e19; text-transform: uppercase; font-size: .9em; text-align: center; padding-bottom: .5em; margin-top: 1em; margin-bottom: 0; } #content div.chapters h3 a { color: #ff6e19; } /* accordion */ #accordion { width: 226px; border-top: 1px solid #c5e3f8; } #accordion ul { padding-left: 0; margin-top: 0; margin-bottom: 0; margin-left: 0; } /* area to the right of the accordion */ #content div.training-body { float: left; padding-left: 0px; width: 748px; line-height: 1.3em; }

  • A script that writes errors and should create a event-error

    - by helmich
    this if it works should check the internet connection if there is a connection it does nothing. if there isn't a connection it should write a error in a txtfile if that happend 5 times it should create a error but it doesn't I will show you the whole code that i have now and the piece of code that i want in a loop. I can't get it in the way i want. I want it to creat 1 Event-error after 5 times writing to the file. this is the whole code i will put the code i want in a loop under it strDirectory = "Z:\text2" strFile = "\foutmelding.txt" strText = "De connectie is verbroken" strWebsite = "www.helmichbeens.com" If PingSite(strWebsite) Then WScript.Quit 'Website is pingable - no further action required Set objFSO = CreateObject("Scripting.FileSystemObject") RecordSingleEvent Dim fout For fout = 1 To 5 : Do If fout = 5 Then Exit Do Set WshShell = WScript.CreateObject("WScript.Shell") Call WshShell.LogEvent(1, "Test Event") Loop While False : next '------------------------------------ 'Record a single event in a text file '------------------------------------ Sub RecordSingleEvent If Not objFSO.FolderExists(strDirectory) Then objFSO.CreateFolder(strDirectory) Set objTextFile = objFSO.OpenTextFile(strDirectory & strFile, 8, True) objTextFile.WriteLine(Now & strText) objTextFile.Close End sub '---------------- 'Ping my web site '---------------- Function PingSite( myWebsite ) Set objHTTP = CreateObject( "WinHttp.WinHttpRequest.5.1" ) objHTTP.Open "GET", "http://" & myWebsite & "/", False objHTTP.SetRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MyApp 1.0; Windows NT 5.1)" On Error Resume Next objHTTP.Send PingSite = (objHTTP.Status = 200) On Error Goto 0 End Function '----------------------------------------------- 'Counts the number of lines inside the text file '----------------------------------------------- Function EventCount(fout) strData = objFSO.OpenTextFile(strDirectory & strFile,ForReading).ReadAll arrLines = Split(strData,vbCrLf) EventCount = UBound(arrLines) End Function This is the whole code, and it doesnt work correctly becaus it creats a event-log rightaway and it should do that after the script has written 5 times to the textfile here is the code that writes to a textfile Sub RecordSingleEvent If Not objFSO.FolderExists(strDirectory) Then objFSO.CreateFolder(strDirectory) Set objTextFile = objFSO.OpenTextFile(strDirectory & strFile, 8, True) objTextFile.WriteLine(Now & strText) objTextFile.Close End sub and here is the code but this part doesnt not work or atleast i think it is this part Dim fout For fout = 1 To 5 : Do If fout = 5 Then Exit Do Set WshShell = WScript.CreateObject("WScript.Shell") Call WshShell.LogEvent(1, "Test Event") Loop While False : next Function EventCount(fout) strData = objFSO.OpenTextFile(strDirectory & strFile,ForReading).ReadAll arrLines = Split(strData,vbCrLf) EventCount = UBound(arrLines) End Function this is the not working part and I don't know what to do anymore so can you please take a look at it tank you very much. btw: this code can be very usefull for a network administrator
