  • Need help with cycle in JS

    - by antiarchitect
    I have such function, that adds a grid of droppables: function AddClassroomDrops(grid, weeks, days, times) { for(week = 1; week <= weeks; week++) { for (day = 1; day <= days; day++) { for (time = 1; time <= times; time++ ) { Droppables.add('container_grid'+ grid + '_week' + week + '_day' + day + '_time' + time, { accept: 'pair', hoverclass : 'hovered_receiver', onDrop: function(pair, receiver) { new Ajax.Request( '/pairs/'+pair.id+'/update_on_drop', { method : 'put', parameters : { classroom : grid, week : week, day : day, time : time, container : receiver.id } } ); } }); } } } } The problem is that params of Ajax.Request (week, day, time) are always equal to weeks + 1, times + 1, days + 1. But they must vary according to the cycle.

  • Help converting code using httlib2 to use urllib2

    - by ThinkCode
    What am I trying to do? Visit a site, retrieve cookie, visit the next page by sending in the cookie info. It all works but httplib2 is giving me one too many problems with socks proxy on one site. http = httplib2.Http() main_url = 'http://mywebsite.com/get.aspx?id='+ id +'&rows=25' response, content = http.request(main_url, 'GET', headers=headers) main_cookie = response['set-cookie'] referer = 'http://google.com' headers = {'Content-type': 'application/x-www-form-urlencoded', 'Cookie': main_cookie, 'User-Agent' : USER_AGENT, 'Referer' : referer} How to do the same exact thing using urllib2 (cookie retrieving, passing to the next page on the same site)? Thank you.

  • Help a Beginner with a PHP based Login System

    - by Brian Lang
    I'm a bit embarrassed to say, but I've run into issue with creating a PHP based login system. I'm using a site template to handle the looks of the the login process, so I will spare you the code. Here is my thought process on how to handle the login: Create a simple login.php file. On there will be a form whose action is set to itself. It will check to see if the submit has been clicked, and if so validate to make sure the user entered a valid password / username. If they do, set a session variable save some login info (username, NOT password), and redirect them to a restricted area. If the login info isn't valid, save an error message in a session variable, display error message giving further instruction, and wait for the user to resubmit. Here is a chunk of what I have - hopefully one of you experts can see where I've gone wrong, and give me some insight: if(isset($_POST['submit'])) { if(!empty($_POST['username']) AND !empty(!$_POST['password'])) { header("Location: http://www.google.com"); } else { $err = 'All the fields must be filled in!'; } } if($err) { $_SESSION['msg']['login-err'] = $err; } ? Now the above is just an example - the intent of the above code is to process user input, with the script validating simply that the user has given input for username and password. If they have, I would like them, in this case, to be redirected to google.com (for the sake of this example). If not, save an error message. Given my current code, the error message will display perfectly, however if the user submits and has something entered for the username and password, the page simply doesn't redirect. I'm sure this is a silly question, but I am a beginner, and well, to be honest, a bit buzzed right now. Thanks so much!

  • jquery tabs with form help

    - by sico87
    Hello, I am implementing jQuery tabs on mysite, one of the tabs holds a form and this is my problem, the form is loaded in via ajax as it is used multiple time throughout the site. My issue is that when the form is submitted the page leaves the tabbed area, whereas I need to stay within the tabbed system. Below is the code I am using TABS HTML <div id="tabs"> <ul> <li><a href="#tabs-1">Active Categories</a></li> <li><a href="#tabs-2">De-activated Categories</a></li> <li><a href="<?=base_url();?>admin/addCategory">Add A New Category</a></li> </ul> FORM MARKUP <div id="contact_form"> <?php // open the form echo form_open(base_url().'admin/addCategory'); // categoryTitle echo form_label('Category Name', 'categoryTitle'); echo form_error('categoryTitle'); $data = array( 'name' => 'categoryTitle', 'id' => 'categoryTitle', 'value' => $categoryTitle, ); echo form_input($data); // categoryAbstract $data = array( 'name' => 'categoryAbstract', 'id' => 'categoryAbstract wysiwyg', 'value' => $categoryAbstract, ); echo form_label('Category Abstract', 'categoryAbstract'); echo form_error('categoryAbstract'); echo form_textarea($data); // categorySlug $data = array( 'name' => 'categorySlug', 'id' => 'categorySlug', 'value' => $categorySlug, ); echo form_label('Category Slug', 'categorySlug'); echo form_error('categorySlug'); echo form_input($data); // categoryIsSpecial /*$data = array( 'name' => 'categoryIsSpecial', 'id' => 'categoryIsSpecial', 'value' => '1', 'checked' => $checkedSpecial, ); echo form_label('Is Category Special?', 'categoryIsSpecial'); echo form_error('categoryIsSpecial'); echo form_checkbox($data);*/ // categoryOnline $data = array( 'name' => 'categoryOnline', 'id' => 'categoryOnline', 'value' => '1', 'checked' => $checkedOnline, ); echo form_label('Online?', 'categoryOnline'); echo form_checkbox($data); echo form_error('categoryOnline'); //hidden field check if we are adding or editing echo form_hidden('edit', $edit); echo form_hidden('categoryId', $categoryId); // categorySubmit $data = array('class' => 'submit', 'id' => 'submit', 'value'=>'Submit', 'name' => 'categorySubmit'); echo form_submit($data); echo form_close(); ?> </div> FORM PROCESS function saveCategory() { $data = array(); // we need to set the what element the form errors get displayed in $this->form_validation->set_error_delimiters('<div class="formError">', '</div>'); // we need to estabilsh some rules so the form can be submitted without error, // or if there is error then the form needs show errors. $config = array( array( 'field' => 'categoryTitle', 'label' => 'Category title', 'rules' => 'required|trim|max_length[25]|xss_clean' ), array( 'field' => 'categoryAbstract', 'label' => 'Category abstract', 'rules' => 'required|trim|max_length[150]|xss_clean' ), array( 'field' => 'categorySlug', 'label' => 'Category slug', 'rules' => 'required|trim|alpha|max_length[25]|xss_clean' ), /*array( 'field' => 'categoryIsSpecial', 'label' => 'Special category', 'rules' => 'trim|xss_clean' ),*/ array( 'field' => 'categoryOnline', 'label' => 'Category online', 'rules' => 'trim|xss_clean' ) ); $this->form_validation->set_rules($config); // with the validation rules set we can no run the validation rules over the form // if any the validation returns false then the error messages will be returned to the view // in the delimiters that we set further up the page. if($this->form_validation->run() == FALSE) { // we should reload the form $this->load->view('admin/add_category'); } }

  • I need help with creating a data structure in PHP

    - by alex
    What I need to do is have a data structure that shows jobs organised into 14 day periods, but only when an id is the same. I've implemented all sorts of stuff, but they have failed miserably. Ideally, maybe a SQL expert could handle all of this in the query. Here is some of my code. You can assume all library stuff works as expected. $query = 'SELECT date, rig_id, comments FROM dor ORDER BY date DESC'; $dors = Db::query(Database::SELECT, $query)->execute()->as_array(); This will return all jobs, but I need to have them organised by 14 day period with the same rig_id value. $hitches = array(); foreach($dors as $dor) { $rigId = $dor['rig_id']; $date = strtotime($dor['date']); if (empty($hitches)) { $hitches[] = array( 'rigId' => $rigId, 'startDate' => $date, 'dors' => array($dor) ); } else { $found = false; foreach($hitches as $key => $hitch) { $hitchStartDate = $hitch['startDate']; $dateDifference = abs($hitchStartDate - $date); $isSameHitchTimeFrame = $dateDifference < (Date::DAY * 14); if ($rigId == $hitch['rigId'] AND $isSameHitchTimeFrame) { $found = true; $hitches[$key]['dors'][] = $dor; } } if ($found === false) { $hitches[] = array( 'rigId' => $rigId, 'startDate' => $date, 'dors' => array($dor) ); } } } This seems to work OK splitting up by rig_id, but not by date. I also think I'm doing it wrong because I need to check the earliest date. Is it possible at all to do any of this in the database query? To recap, here is my problem I have a list of jobs with all have a rig_id (many jobs can have the same) and a date. I need the data to be organised into hitches. That is, the rig_id must be the same per hitch, and they must span a 14 day period, in which the next 14 days with the same rig_id will be a new hitch. Can someone please point me on the right track? Cheers

  • Help with Arrays in Objective C.

    - by NJTechie
    Problem : Take an integer as input and print out number equivalents of each number from input. I hacked my thoughts to work in this case but I know it is not an efficient solution. For instance : 110 Should give the following o/p : one one zero Could someone throw light on effective usage of Arrays for this problem? #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int input, i=0, j,k, checkit; int temp[i]; NSLog(@"Enter an integer :"); scanf("%d", &input); checkit = input; while(input > 0) { temp[i] = input%10; input = input/10; i++; } if(checkit != 0) { for(j=i-1;j>=0;j--) { //NSLog(@" %d", temp[j]); k = temp[j]; //NSLog(@" %d", k); switch (k) { case 0: NSLog(@"zero"); break; case 1: NSLog(@"one"); break; case 2: NSLog(@"two"); break; case 3: NSLog(@"three"); break; case 4: NSLog(@"four"); break; case 5: NSLog(@"five"); break; case 6: NSLog(@"six"); break; case 7: NSLog(@"seven"); break; case 8: NSLog(@"eight"); break; case 9: NSLog(@"nine"); break; default: break; } } } else NSLog(@"zero"); [pool drain]; return 0; }

  • Help with query

    - by hdoe123
    Hi, I'm trying make a query that looks at a single table and looks to see if a student is a team called CMHT and in a medic team - if they are I don't want to see the result. I only want see if there only in CMHT or medic not both. Would the right direction be using sub query to filer it out? I've done a search on NOT IN but how could you get to see check if its in more then 2 teams are not? Student Team ref 1 CMHT 1 1 Medic 2 2 Medic 3 this would be in the result 3 CMHT 5 this would be in the result So far I've done the following code would I need use a sub query or do a self join and filter it that way? SELECT Table1.Student, Table1.Team, Table1.refnumber FROM Table1 WHERE (((Table1.Team) In ('Medics','CMHT'))

  • Help decoupling Crystal Report from CrystalReportViewer

    - by John at CashCommons
    I'm using Visual Studio 2005 with VB.NET. I have a number of Crystal Reports, each with their own associated dialog resource containing a CrystalReportViewer. The class definitions look like this: Imports System.Windows.Forms Imports CrystalDecisions.CrystalReports.Engine Imports CrystalDecisions.Shared Public Class dlgForMyReport Private theReport As New myCrystalReport Public theItems As New List(Of MyItem) Private Sub OK_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK_Button.Click Me.DialogResult = System.Windows.Forms.DialogResult.OK Me.Close() End Sub Private Sub Cancel_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Cancel_Button.Click Me.DialogResult = System.Windows.Forms.DialogResult.Cancel Me.Close() End Sub Private Sub dlgForMyReport_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load theReport.SetDataSource(theItems) 'Do a bunch of stuff here to set data items in theReport Me.myCrystalReportViewer.ReportSource = theReport End Sub End Class I basically instantiate the dialog, set theItems to the list I want, and call ShowDialog. I now have a need to combine several of these reports into one report (possibly like this) but the code that loads up the fields in the report is in the dialog. How would I go about decoupling the report initialization from the dialog? Thanks!

  • Will an Nginx as reverse proxy for Apache help on dynamic content only

    - by Saif Bechan
    I am planning to move all my static content to a CDN so on my server I only have dynamic content left. I now have Nginx set up as reverse proxy to Apache. The static request that came in where directly delivered by Nginx without having to go to Apache. In this case Nginx handled a large portion of the request and I can clearly see the necessity of Nginx. Now that I moved all the static content to another domain, is there still a need to have nginx in front of Apache. Because now all the request are by default dynamic requests and all go to Apache. Are there any other benefits of having Nginx and Apache running for only dynamic content. My dynamic content is PHP/MySQL Edit: To be clear: I now have Nginx as a reverse proxy. It delivers static and dynamic content. But I am moving my static files to a CDN. Do I then still need Nginx on my domain.

  • Getting a screenshot of a page using .NET - Need help with code

    - by Ender
    I'm writing a specialized crawler and parser for internal use and I require the ability to take a screenshot of a web page in order to check what colours are being used throughout. The program will take in around ten web addresses and will save them as a bitmap image, from there I plan to use LockBits in order to create a list of the five most used colours within the image. To my knowledge it's the easiest way to get the colours used within a web page but if there is an easier way to do it please chime in with your suggestions. Anyway, I was going to use this program until I saw the price tag. I'm also fairly new to C#, having only used it for a few months. Can anyone provide me with a solution to my problem of taking a screenshot of a web page in order to extract the colour scheme? EDIT: Sorry for not getting back to this sooner, but I've been busy with some other things. Anyway, the code seems to work well, but the problem I am having right now is that I am running it within a form, and naturally with Application.Run() being called I cannot run two instances of the same form at once. It recommended Form.showDialog() but that broke everything. Can anyone give me a hand with this code? public static void buildScreenshotFromURL(string url) { int width = 800; int height = 600; using (WebBrowser browser = new WebBrowser()) { browser.Width = width; browser.Height = height; browser.ScrollBarsEnabled = true; // This will be called when the page finishes loading browser.DocumentCompleted += new System.Windows.Forms.WebBrowserDocumentCompletedEventHandler(OnDocumentCompleted); //browser.DocumentCompleted += OnDocumentCompleted; browser.Navigate(url); // This prevents the application from exiting until // Application.Exit is called // Application.Run() does not work as it cannot be called twice, recommended form.showDialog() // but still issues Application.Run(); } } public static void OnDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { // Define size of thumbnail neded int thumbSize = 50; // Now that the page is loaded, save it to a bitmap WebBrowser browser = (WebBrowser)sender; // Code edited from example below to make smaller bitmap and save as PNG using (Graphics graphics = browser.CreateGraphics()) { using (Bitmap bitmap = new Bitmap(browser.Width, browser.Height, graphics)) { Rectangle bounds = new Rectangle(0, 0, bitmap.Width, bitmap.Height); browser.DrawToBitmap(bitmap, bounds); Bitmap thumbBitmap = new Bitmap(bitmap.GetThumbnailImage(thumbSize, thumbSize, thumbCall, IntPtr.Zero)); thumbBitmap.Save("screenshot.png", ImageFormat.Png); handleImage(thumbBitmap); } }

There are two things that I want to ask in this- What is the significance of calling the constructor of the parent class with the event arg? super(LOGIN) in the example Why do you need to overrride the clone method? Understanding these things will give me a better insight into the way things are done with Cairngorm. Thanks

  • Help to restructure my Doc/View more correctly

    - by Harvey
    Edited by OP. My program is in need of a lot of cleanup and restructuring. In another post I asked about leaving the MFC DocView framework and going to the WinProc & Message Loop way (what is that called for short?). Well at present I am thinking that I should clean up what I have in Doc View and perhaps later convert to non-MFC it that even makes sense. My Document class currently has almost nothing useful in it. I think a place to start is the InitInstance() function (posted below). In this part: POSITION pos=pDocTemplate->GetFirstDocPosition(); CLCWDoc *pDoc=(CLCWDoc *)pDocTemplate->GetNextDoc(pos); ASSERT_VALID(pDoc); POSITION vpos=pDoc->GetFirstViewPosition(); CChildView *pCV=(CChildView *)pDoc->GetNextView(vpos); This seem strange to me. I only have one doc and one view. I feel like I am going about it backwards with GetNextDoc() and GetNextView(). To try to use a silly analogy; it's like I have a book in my hand but I have to look up in it's index to find out what page the Title of the book is on. I'm tired of feeling embarrassed about my code. I either need correction or reassurance, or both. :) Also, all the miscellaneous items are in no particular order. I would like to rearrange them into an order that may be more standard, structured or straightforward. ALL suggestions welcome! BOOL CLCWApp::InitInstance() { InitCommonControls(); if(!AfxOleInit()) return FALSE; // Initialize the Toolbar dll. (Toolbar code by Nikolay Denisov.) InitGuiLibDLL(); // NOTE: insert GuiLib.dll into the resource chain SetRegistryKey(_T("Real Name Removed")); // Register document templates CSingleDocTemplate* pDocTemplate; pDocTemplate = new CSingleDocTemplate( IDR_MAINFRAME, RUNTIME_CLASS(CLCWDoc), RUNTIME_CLASS(CMainFrame), RUNTIME_CLASS(CChildView)); AddDocTemplate(pDocTemplate); // Parse command line for standard shell commands, DDE, file open CCmdLineInfo cmdInfo; ParseCommandLine(cmdInfo); // Dispatch commands specified on the command line // The window frame appears on the screen in here. if (!ProcessShellCommand(cmdInfo)) { AfxMessageBox("Failure processing Command Line"); return FALSE; } POSITION pos=pDocTemplate->GetFirstDocPosition(); CLCWDoc *pDoc=(CLCWDoc *)pDocTemplate->GetNextDoc(pos); ASSERT_VALID(pDoc); POSITION vpos=pDoc->GetFirstViewPosition(); CChildView *pCV=(CChildView *)pDoc->GetNextView(vpos); if(!cmdInfo.m_Fn1.IsEmpty() && !cmdInfo.m_Fn2.IsEmpty()) { pCV->OpenF1(cmdInfo.m_Fn1); pCV->OpenF2(cmdInfo.m_Fn2); pCV->DoCompare(); // Sends a paint message when complete } // enable file manager drag/drop and DDE Execute open m_pMainWnd->DragAcceptFiles(TRUE); m_pMainWnd->ShowWindow(SW_SHOWNORMAL); m_pMainWnd->UpdateWindow(); // paints the window background pCV->bDoSize=true; //Prevent a dozen useless size calculations return TRUE; } Thanks

  • Help needed with drawRect:

    - by Andrew Coad
    Hi, I'm having a fundamental issue with use of drawRect: Any advice would be greatly appreciated. The application needs to draw a variety of .png images at different times, sometimes with animation, sometimes without. A design goal that I was hoping to adhere to is to have the code inside drawRect: very simple and "dumb" - i.e. just do drawing and no other application logic. To draw the image I am using the drawAtPoint: method of UIImage. Since this method does not take a CGContext as a parameter, it can only be called within the drawRect: method. So I have: - (void)drawRect:(CGRect)rect { [firstImage drawAtPoint:CGPointMake(firstOffsetX, firstOffsetY)]; } All fine and dandy for one image. To draw multiple images (over time) the approach I have taken is to maintain an array of dictionaries with each dictionary containing an image, the point location to draw at and a flag to enable/suppress drawing for that image. I add dictionaries to the array over time and trigger drawing via the setNeedsDisplay: method of UIView. Use of an array of dictionaries allows me to completely reconstruct the entire display at any time. drawRect: now becomes: - (void)drawRect:(CGRect)rect { for (NSMutableDictionary *imageDict in [self imageDisplayList]) { if ([[imageDict objectForKey:@"needsDisplay"] boolValue]) { [[imageDict objectForKey:@"image"] drawAtPoint:[[imageDict objectForKey:@"location"] CGPointValue]]; [imageDict setValue:[NSNumber numberWithBool:NO] forKey:@"needsDisplay"]; } } } Still OK. The code is simple and compact. Animating this is where I run into problems. The first problem is where do I put the animation code? Do I put it in UIView or UIViewController? If in UIView, do I put it in drawRect: or elsewhere? Because the actual animation depends on the overall state of the application, I would need nested switch statements which, if put in drawRect:, would look something like this: - (void)drawRect:(CGRect)rect { for (NSMutableDictionary *imageDict in [self imageDisplayList]) { if ([[imageDict objectForKey:@"needsDisplay"] boolValue]) { switch ([self currentState]) { case STATE_1: switch ([[imageDict objectForKey:@"animationID"] intValue]) { case ANIMATE_FADE_IN: [self setAlpha:0.0]; [UIView beginAnimations:[[imageDict objectForKey:@"animationID"] intValue] context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; [UIView setAnimationDuration:2]; [self setAlpha:1.0]; break; case ANIMATE_FADE_OUT: [self setAlpha:1.0]; [UIView beginAnimations:[[imageDict objectForKey:@"animationID"] intValue] context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; [UIView setAnimationDuration:2]; [self setAlpha:0.0]; break; case ANIMATE_OTHER: // similar code here break; default: break; } break; case STATE_2: // similar code here break; default: break; } [[imageDict objectForKey:@"image"] drawAtPoint:[[imageDict objectForKey:@"location"] CGPointValue]]; [imageDict setValue:[NSNumber numberWithBool:NO] forKey:@"needsDisplay"]; } } [UIView commitAnimations]; } In addition, to make multiple sequential animations work correctly, there would need to be an outer controlling mechanism involving the animation delegate animationDidStop: callback that would set the needsDisplay entries in the dictionaries to allow/suppress drawing (and animation). The point that we are at now is that it all starts to look very ugly. More specifically: drawRect: starts to bloat quickly and contain code that is not "just drawing" code the UIView needs implicit awareness of the application state the overall process of drawing is now spread across three methods at a minimum And on to the point of this post: how can I do this better? What would the experts out there recommend in terms of overall structure? How can I keep application state information out of the view? Am I looking at this problem from the wrong direction. Is there some completely different approach that I should consider?
