  • MVC Validator numberOfInvalids not working

    - by user965445
    I dynamically add some elements to a form so I know I need to re-parse the form. Even if I have old invalid elements they don't get identified in numberOfInvalids It always comes back = 0 even though the invalid fields are highlighted on the page. var form = $("#form"); //Form Savingform.submit(function (e) { e.preventDefault(); form.removeData("validator"); form.removeData("unobtrusiveValidation"); $.validator.unobtrusive.parse(form); var val = form.validate(); if (val.numberOfInvalids() == 0) { $.blockUI({ fadeIn: 1000 }); AjaxRequest({ data: $(this).serializeArray(), success: function (data, status, xhr) { alert('sucess save or submit, use "'); }, complete: function () { $.unblockUI(); } }); } });

  • bandwidth throttling C linux

    - by bob moch
    hi im currently creating a function to create a sleep time i can pause between packets for my port scanner im creating for personal/educational use for my home network. what im currently doing is opening /proc/net/dev and reading the 9th set of digits for the eth0 interface to find out the current packets being set and then reading it again and doing some math to figure out a delay to sleep between sending a packet to a port to identify it and fingerprint it. my problem is that no matter what throttle % i use it always seems to send the same rate of packets. i think its mainly my way of mathematically creating my sleep delay. edit:: dont mind the function declaration and the struct stuff all im doing is spawning this function in a thread and passing a pointer to a struct to the function, recreating the struct locally and then freeing the passed structs memory. void *bandwidthmonitor_cmd(void *param) { char cmdline[1024], *bytedata[19]; int i = 0, ii = 0; long long prevbytes = 0, currentbytes = 0, elapsedbytes = 0, byteusage = 0, maxthrottle = 0; command_struct bandwidth = *((command_struct *)param); free(param); //printf("speed: %d\n throttle: %d\n\n", UPLOAD_SPEED, bandwidth.throttle); maxthrottle = UPLOAD_SPEED * bandwidth.throttle / 100; //printf("max throttle:%lld\n", maxthrottle); FILE *f = fopen("/proc/net/dev", "r"); if(f != NULL) { while(1) { while(fgets(cmdline, sizeof(cmdline), f) != NULL) { cmdline[strlen(cmdline)] = '\0'; if(strncmp(cmdline, " eth0", 6) == 0) { bytedata[0] = strtok(cmdline, " "); while(bytedata[i] != NULL) { i++; bytedata[i] = strtok(NULL, " "); } bytedata[i + 1] = '\0'; currentbytes = atoi(bytedata[9]); } } i = 0; rewind(f); elapsedbytes = currentbytes - prevbytes; prevbytes = currentbytes; byteusage = 8 * (elapsedbytes / 1024); //printf("usage:%lld\n",byteusage); if(ii & 0x40) { SLEEP += (maxthrottle - byteusage) * -1.1;//-2.5; if(SLEEP < 0){ SLEEP = 0; } //printf("sleep:%d\n", SLEEP); } usleep(25000); ii++; } } return NULL; } SLEEP and UPLOAD_SPEED are global variables and UPLOAD_SPEED is in kb/s and generated via a speedtest function that gets the upload speed of my computer. this function is running inside a POSIX thread updating SLEEP which my threads doing the socket work grab to sleep by after every packet. as testing instead of only doing the ports i want to check i make it do all the ports over and over again so i can run dstat on a machine to check bandwidth and no matter what bandwidth.throttle is set to it always seems to generate the same amount of bandwidth to the dstat machine. the way i calculate how much i "should" throttle by is by finding the maximum throttle speed which is defined as maxthrottle = upload_speed * throttle / 100; for example if my upload speed was 1000kb/s and my throttle was 90 (90%) my max throttle would be 900kb/s from there it would find the current bytes sent from /proc/net/dev and then find my sleep time via incrementing or decrementing it via sleep += (maxthrottle - bytesysed) * -1.1; this should in theory increase or decrease the sleep time based on how many bytes used there are. the if(ii & 0x40) statement is just for some moderation control. it makes it so it only sets sleep to a new time every 30-40 iterations. final notes: the main problem is that the sleep timer does not seem to modify the speed of packets being set. or maybe its just my implementation because on a freshly restarted machine where /proc/net/dev has low numbers of bytes sent it seems to raise the sleep timer accordingly on my 60kb/s upload machine (ex if i set the throttle to 2 it will incline the sleep timer until network bandwidth out reaches the max bandwidth threshold, but when i try running it on a server which as been online forever it doesnt seem to work as nicely if at all. if anyone can suggest a new method of monitoring the network to adjust a sleep delay then let me know or if anyone sees a flaw in my code. thank you.

  • jquery plugin pattern using jquery.data

    - by web_dev
    I have seen this piece of code in jquery plugin patterns and the notes section mention that we could attach the plugin to the DOM element using the jQuery.data function. What I don't understand is how do I make use of this piece of code. Can somebody provide examples of how to use this functionality and explain its significance? $.fn[pluginName] = function (options) { return $Extend(this).each(function () { if (!$.data(this, 'plugin_' + pluginName)) { $.data(this, 'plugin_' + pluginName, new Plugin( this, options )); } }); };

  • How can I change this method to get rid of the warning without anything changing?

    - by user3591323
    So this question:Warning-used as the name of the previous parameter rather than as part of the selector answers part of my problem, but I really don't want anything to change inside this method and I'm a bit confused on how this works. Here's the whole method: -(void) SetRightWrong:(sqzWord *)word: (int) rightWrong { if (self.mastered==nil) { self.mastered = [[NSMutableArray alloc]initWithCapacity:10]; } //if right change number right if (rightWrong == 1) { word.numberCorrect++; //if 3 right move to masterd list [self.onDeck removeObject:word]; if(word.numberCorrect >= 3 ) { [self.mastered addObject:word]; } else { //if not 3 right move to end of ondeck [self.onDeck addObject:word]; } } else if(rightWrong == 0) { //if wrong remove one from number right unless 0 NSUInteger i; i=[self.onDeck indexOfObject:word]; word = [self.onDeck objectAtIndex:i]; if (word.numberCorrect >0) { word.numberCorrect--; } } } The warning I am getting is: 'word' used as the name of the previous parameter than as part of the selector.

  • How to do a for loop in windows command line?

    - by TheFoxx
    I was wondering if this was possible? I'm not familiar with using windows command line, but I have to use it for a project I'm working on. I have a a number of files, for which I need to perform a function for each. I'm used to working with python, but obviously this is a bit different, so I was hoping for some help. Basically I need the for loop to iterate through 17 files in a folder, perform a function on each (that's using the specific software I have here for the project) and then that will output a file with a unique name (the function normally requires me to state the output file name) I would suck it up and just do it by hand for each of the 17, but basically it's creating a database of a file, and then comparing it to each of the 17. It needs to be iterated through several hundred times though. Using a for loop could save me days of work. Suggestions?

  • allow waiting user experience while file upload with rails and jquery

    - by poseid
    I am trying to display a waiting spinnger, while uploading a file. I am able to show the spinner, and to do the upload, when doing it individually. My problem is how to combine these two. The Jquery Javascript looks like: <% javascript_tag do %> function showLoading() { $("#loading").show(); } function hideLoading() { $("#loading").hide(); } function submitCallback() { showLoading(); $.post("create"); } <% end % My form looks like: <% semantic_form_for @face, :html => {:multipart => true} do |f| %> <%= f.error_messages %> <%= render 'fields', :f => f %> <p> <%= button_to_function 'create', "submitCallback()" %> </p> <% end %>

  • Porting Windows C++ to Standard (Linux) C++ - WSAGetLastError()

    - by Donal Rafferty
    I am currently porting some Windows mobile C++ code to standard C++. So I am trying to find alternatives for windows specific functions. I have had very little luck in finding a standard C++ function that can help me replace the WSAGetLastError() windows specific function. WSAGetLastError() returns error numbers for errors that occur with sockets in windows. So I was wondering if anyone was aware of a way to replace this function in standard c++? A way to get different error numbers for different outcomes of connecting/dissconection a socket would be sufficent.

  • WorkFlow and WCF dynamically launching WorkFlows

    - by Raj73
    I have a WF which will be hosted on WCF . The service Contract will contain a single operation containing two parameters. Parameter1 will be a string and will contain the name of the workflow to invoke and parameter two will contain the input for the invoked Work Flow. All operations will take the same parameter. All the operations will return the same return value. I have created the service implementation and I would like to depending on the value of parameter1 start executing the appropriate workflow and return the value (There can be number of workflow classes say Operation1, Operation2...which will be the passed in as the value in Parameter1). How can I instantiate different workflow classes and pass parameters and get the return values from them which I should then pass back to the calling Client. (Also Should I be using ReceiveActivities in all of my Launchable WorkFlow Classes ? ) Any code samples or pointers would help

  • Design report of 4-D data set

    - by phq
    I'm writing a report generator that will present data each being generated from 4 parameters. Time interval Group Measurement value(one of several to choose from) Device All these are orthogonal giving me a 4-D dataset to present. There are some simplifications where one parameter is the same for all and other parameters are merged. Still it appears as there are situations where all values are wanted on the report. In short the report should both be simple to overview and contain details. There will also be an interface where the user setup the range and granularity for each parameter. The most naive solution would be to have a 2D table where each cell contain another table with values of the remaining two dimensions. This is technically feasible but I'm worried that it would become hard to overview. Another approach is to present first two dimensions in a 2D table and the remaining parameters in groups Are there any good method to address this kind of issue?

  • How do you pass an enum by reference?

    - by Darkenor
    I have an enum with four keys I'm taking as input for an interface program and I'd like to pass the enum by value to the interface function, which has become quite long. The enum is like this: enum MYKEYS { W, S, O, L }; There's also a boolean array that I have to pass by reference, which is also a little tricky. bool key[4] = { false, false, false, false }; Does anyone know the proper syntax to pass both of these as reference in a function, similar to: function(int & anintreference);

  • Does remove a DOM object (in Javascript) will cause Memory leak if it has event attached?

    - by seatoskyhk
    So, if in the javascript, I create a DOM object in the HTML page, and attach event listener to the DOM object, upon I remove the the DOM from HTML page, does the event listener still exist and causing memory leak? function myTest() { var obj = document.createElement('div'); obj.addEventListener('click', function() {alert('whatever'); }); var body = document.getElementById('body'); // assume there is a <div id='body'></div> already body.appendChild(obj); } // then after some user actions. I call this: function emptyPage() { var body = document.getElementById('body'); body.innerHTML = ''; //empty it. } So, the DOM object, <div> inside body is gone. But what about the eventlistener? I'm just afraid that it will cause memory leak.

  • jQuery - Using .one() with hover

    - by Jared
    Is there any way to get a hover function to only execute once? This is what I'm currently trying: $('#ask').live('hover', function() { $('#homesearch-after').hide(300); $.doTimeout( 300, function() { hideClosedSearchLink(); showHomeSearch(); }); }); But that's not working. How can I only get this hover to activate once? I've tried changing .live with .one and .bind... resulting in nothingness.

  • When is a Cocoa callback given controll?

    - by Kaspa
    Hi, I've been searching around the web for an answer to this one, but was unable to find an answer, on the other side I think it's something quite common thus there is a possibility I'm missing some keywords here. Anyhow, the problem is as follows: When is control given to a callback function in ObjC (iPhone)? Does it happen after control is given to a high up in the hierarchy class responsible for the runloop? Can it occur in the middle of another function call being executed? As an example, let's take the NSURLConnection, we don't know or can't predict when it's going to call didReceiveResponse or the other callback methods, can it be the case that didReceiveResponse get's called when I'm in the middle of another function? (highly doubt that but was unable to find information on callbacks wating for the end of the run loop) Cheers, Kaspa

  • jQuery: Listen to changes within a DIV and act accordingly

    - by Chris
    I have a function that grabs an XML document and transforms it according to an XSL document. It then places the result into a div with the id laneconfigdisplay. What I want to do is, separate to the transformation logic, setup a jQuery change event for that div so I can tell when it has changed, and run some jQuery code. I have tried the following, but it does not work! $(document).ready(function() { $('#laneconfigdisplay').change(function() { alert('woo'); }); //Do XML / XSL transformation here }); <!-- HTML code here --> <div id="laneconfigdisplay"></div> What am I doing wrong?

  • Django store regular expression in DB which then gets evaluated on page

    - by John
    Hi, I want to store a number of url patterns in my django model which a user can provide parameters to which will create a url. For example I might store these 3 urls in my db where %s is the variable parameter provided by the user: www.thisissomewebsite.com?param=%s www.anotherurl/%s/ www.lastexample.co.uk?param1=%s&fixedparam=2 As you can see from these examples the parameter can appear anywhere in the string and not in a fixed position. I have 2 models, one holds the urls and one holds the variables: class URLPatterns(models.Model): pattern = models.CharField(max_length=255) class URLVariables(models.Model): pattern = models.ForeignKey(URLPatterns) param = models.CharField(max_length=255) What would be the best way to generate these urls by replacing the %s with the variable in the database. would it just be a simple replace on the string e.g: urlvariable = URLVariable.objects.get(pk=1) pattern = url.pattern url = pattern.replace("%s", urlvariable.param) or is there a better way? Thanks

  • Too many local variables in ASP.NET

    - by Yongwei Xing
    Hi all I wrote a control, and use a tool to do the code analysis. There is a test that I didn't pass. Avoid excessive locals, http://msdn.microsoft.com/library/ms182263(VS.90).aspx. In my CreateChildControls function, I built a big table with lots of field. I need to create a lot of TableRow and TableCell to construct the table. But these are not field or property of control. Thery are local variables in the function, which are created dynamically. Should I make these TableCells and TableRows as fields of the control? Or I just keep them as the local variables in the CreateChildControl function? Best Regards,

  • SQL Server 2008 - Conditional Query

    - by Villager
    Hello, SQL is not one of my strong suits. I have a SQL Server 2008 database. This database has a stored procedure that takes in eight int parameters. For the sake of keeping this question focused, I will use one of these parameters for reference: @isActive int Each of these int parameters will be -1, 0, or 1. -1 means "Unknown" or "Don't Care". Basically, I need to query a table such that if the int parameter is NOT -1, I need to consider it in my WHERE clause. Because there are eight int parameters, an IF-ELSE statement does not seem like a good idea. At the same time, I do not know how else to do this? Is there an elegant way in SQL to add a WHERE conditional if a parameter does NOT equal a value? Thank you!

  • Recursion: using values passed in parameters

    - by Tom Lilletveit
    I got this line of code that pops a int of the array saves it to int element then removes it from array. then in the return statement return CountCriticalVotes(rest, blockIndex + element); it ads it to the blockIndex variable and if it reaches 10 before the array is empty it returns 1. But my problem is this, I do not want it to add up all the values in the array in the parameter, but only add one then revert the parameter value back to it´s original state, then add a new, revert etc... How would i do this? int NumCriticalVotes :: CountCriticalVotes(Vector<int> & blocks, int blockIndex) { if (blockIndex >= 10) { return 1; } if (blocks.isEmpty()) { return 0; } else { int element = blocks.get(0); Vector<int> rest = blocks; rest.remove(0); return CountCriticalVotes(rest, blockIndex + element);
