  • Limit URL Parameter Length in Web.Config

    - by Alex
    Is it possible to add some kind of restriction to the web.config to limit URL parameter length? I want to prevent people at the earliest possible point from submitting too large URL parameters so the server doesn't get taxed more than necessary in the event that somebody tries to "attack" it with large invalid URL parameters.

  • UIButtons creating a native-like keyboard behavior.

    - by camilo
    Greets. A somehow detailed explanation on my problem, and what I have already done, and what I cannot do. I want to create a behavior resembling the one in the iPhone's keyboard. Basically, I want a view to appear when the user taps a button and WHILE the user taps that button. This, I accomplished. When the user lets go of the button WHILE his finger is on that button's area, I want to trigger an action "doing stuff". This, I was also able to do. Since all the buttons are near (like in the keyboard) and I don't want the user to select other button than the one he pressed, I reduced the hit area for the button using the -(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent )event function. When the user presses the button, not lifting its finger, and dragging outside the button area, I want another action to trigger. This is the first problem... This function only triggers when the user's finger is far from the buttons' area, and this time the pointInside function is not being my friend. How can I detect the user finger "left" the button area the moment it exits its bounds? This, in case you didn't realize... was problem 1. The second problem is related with the drag enter. Again, I need to limit the area like in the drag exit. But I suppose that when I solve one of these, the other is the same. The problem is that in order to have a behavior like in the keyboard, I may need to detect the user started the touch in another button, never lifted his finger, and changed to another button. I can detect drag enter and drag exit IN THIS ORDER while on the same button. I cannot detect drag enter when the user first touched anywhere else other than the button where I want to detect the drag enter event. Basically what I need is to detect touch on any button (and not anywhere else in the view), and while the user is changing buttons without lifting the finger, I want to detect the new button being touched. This gigantic paragraph was problem #2. Any help, as you might guess, is highly appreciated. Best Regards. Thanks a lot!

  • Problem to focus JTextField

    - by Tom Brito
    I have used the approach of the ComponentListener to call focus in JTextField within a dialog, but for this case is just not working, I don't know why. It shows the focus in the text field and fast change to the button. Run and see: import java.awt.Component; import java.awt.GridLayout; import java.awt.event.ComponentEvent; import java.awt.event.ComponentListener; import javax.swing.JDialog; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JPanel; import javax.swing.JPasswordField; import javax.swing.JTextField; public class User { private String username = ""; private String password = ""; public User() { // default constructor } public User(String username, String password) { this.username = username; this.password = password; } /** Create a panel containing the componet and tha label. */ public JPanel createLabeledComponent(JLabel label, Component comp) { GridLayout layout = new GridLayout(2, 1); JPanel panel = new JPanel(layout); panel.add(label); panel.add(comp); label.setLabelFor(comp); return panel; } public void showEditDialog() { JLabel usernameLbl = new JLabel(username); final JTextField usernameField = new JTextField(); usernameField.setText(username); JPanel usernamePnl = createLabeledComponent(usernameLbl, usernameField); JLabel passwordLbl = new JLabel(password); JPasswordField passwordField = new JPasswordField(password); JPanel passwordPnl = createLabeledComponent(passwordLbl, passwordField); Object[] fields = { "User:", usernamePnl, "Password:", passwordPnl }; JOptionPane optionPane = new JOptionPane(fields, JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION, null, null); JDialog dialog = optionPane.createDialog("User Data"); dialog.addComponentListener(new ComponentListener() { public void componentShown(ComponentEvent e) { usernameField.requestFocusInWindow(); } public void componentResized(ComponentEvent e) {} public void componentMoved(ComponentEvent e) {} public void componentHidden(ComponentEvent e) {} }); dialog.setVisible(true); } public static void main(String[] args) { new User().showEditDialog(); } } Any idea how to solve this?

  • Rails - good tool to create a scheduled background process which will regularly retrieve messages fr

    - by adam
    Background Job gets mentioned a lot but all the tutorials I've seen seem to indicate that its for queuing jobs which are created by some external event such as a user clicking "Send mail". But what about when you have code that needs to scheduled to run every 30 seconds to listen for new messages from twitter? Normally rake is recommended for set in stone schedules but it inst so efficient for frequent jobs as it has to to load the entire rails app each time. Can anyone recommend anything for this situation?

  • Catch Multiple Custom Exceptions? - C++

    - by Alex
    Hi all, I'm a student in my first C++ programming class, and I'm working on a project where we have to create multiple custom exception classes, and then in one of our event handlers, use a try/catch block to handle them appropriately. My question is: How do I catch my multiple custom exceptions in my try/catch block? GetMessage() is a custom method in my exception classes that returns the exception explanation as a std::string. Below I've included all the relevant code from my project. Thanks for your help! try/catch block // This is in one of my event handlers, newEnd is a wxTextCtrl try { first.ValidateData(); newEndT = first.ComputeEndTime(); *newEnd << newEndT; } catch (// don't know what do to here) { wxMessageBox(_(e.GetMessage()), _("Something Went Wrong!"), wxOK | wxICON_INFORMATION, this);; } ValidateData() Method void Time::ValidateData() { int startHours, startMins, endHours, endMins; startHours = startTime / MINUTES_TO_HOURS; startMins = startTime % MINUTES_TO_HOURS; endHours = endTime / MINUTES_TO_HOURS; endMins = endTime % MINUTES_TO_HOURS; if (!(startHours <= HOURS_MAX && startHours >= HOURS_MIN)) throw new HourOutOfRangeException("Beginning Time Hour Out of Range!"); if (!(endHours <= HOURS_MAX && endHours >= HOURS_MIN)) throw new HourOutOfRangeException("Ending Time Hour Out of Range!"); if (!(startMins <= MINUTE_MAX && startMins >= MINUTE_MIN)) throw new MinuteOutOfRangeException("Starting Time Minute Out of Range!"); if (!(endMins <= MINUTE_MAX && endMins >= MINUTE_MIN)) throw new MinuteOutOfRangeException("Ending Time Minute Out of Range!"); if(!(timeDifference <= P_MAX && timeDifference >= P_MIN)) throw new PercentageOutOfRangeException("Percentage Change Out of Range!"); if (!(startTime < endTime)) throw new StartEndException("Start Time Cannot Be Less Than End Time!"); } Just one of my custom exception classes, the others have the same structure as this one class HourOutOfRangeException { public: // param constructor // initializes message to passed paramater // preconditions - param will be a string // postconditions - message will be initialized // params a string // no return type HourOutOfRangeException(string pMessage) : message(pMessage) {} // GetMessage is getter for var message // params none // preconditions - none // postconditions - none // returns string string GetMessage() { return message; } // destructor ~HourOutOfRangeException() {} private: string message; };

  • Flex: convert VideoPlayer.currentTime to string "00:00:00:000"

    - by numediaweb
    Hi there! what about this one: I want to format the currentTime displayed by a videoPlayer component inside flex, something like : 8230.999 to something like 01:59:59:999 which is "hours:minutes:seconds:milliseconds" I trie different sets of codes but they can't get it to work because currentTime is nor a correct miliseconds time as it adds a floating 3 digit point to seconds; so instead of : 2000ms it outputs 2.000 something people like me just can't understand! thanx for any help :) ### UPDATE I still have problem with milliseconds. here's the current MXML: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ protected function convert_clickHandler(event:MouseEvent):void { var val:Number = new Number(inPut.text); //inPut.text = 1000.001 //val = val * 1000; outPut.text = timeFormat(val); } public static function timeFormat(value:Number):String { var milliseconds:Number = value % 1000; var seconds:Number = Math.floor((value/1000) % 60); var minutes:Number = Math.floor((value/60000) % 60); var hours:Number = Math.floor((value/3600000) % 24); var s_miliseconds:String = (milliseconds<10 ?

  • How can I programmatically add triggers to an ASP.NET UpdatePanel?

    - by scottm
    I am trying to write a quote generator. For each product, there are a set of options. I want to dynamically add a drop down list for each option, and then have their SelectedIndexChanged events all wired up to update the quote cost. I am not having any trouble adding the DropDownList controls to my UpdatePanel, but I can't seem to wire up the events. After the page loads, the drop downs are there, with their data, but changing them does not call the SelectedIndexChanged event handler, nor does the QuoteUpdatePanel update. I have something like this: QuotePanel.ASCX <asp:ScriptManager ID="ScriptManager" runat="server" /> <asp:UpdatePanel ID="QuoteUpdatePanel" runat="server" ChildrenAsTriggers="true"> <ContentTemplate> Cost: <asp:Label ID="QuoteCostLabel" runat="server" /> <fieldset id="standard-options"> <legend>Standard Options</legend> <asp:UpdatePanel ID="StandardOptionsUpdatePanel" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional"> <ContentTemplate> </ContentTemplate> </asp:UpdatePanel> </fieldset> </ContentTemplate> </asp:UpdatePanel> The code to add the dropdowns and the event they are to be wire up for: protected void PopluateUpdatePanel(IQuoteProperty standardOptions) foreach (IQuoteProperty standardOp in standardOptions) { QuotePropertyDropDownList<IQuoteProperty> dropDownList = new QuotePropertyDropDownList<IQuoteProperty>(standardOp); dropDownList.SelectedIndexChanged += new EventHandler(QuotePropertyDropDown_SelectedIndexChanged); dropDownList.ID = standardOp.GetType().Name + "DropDownList"; ScriptManager.RegisterAsyncPostBackControl(dropDownList); Label propertyLabel = new Label() {Text = standardOp.Title, CssClass = "quote-property-label"}; this.StandardOptionsUpdatePanel.ContentTemplateContainer.Controls.Add(propertyLabel); this.StandardOptionsUpdatePanel.ContentTemplateContainer.Controls.Add(dropDownList); _standardOptionsListBoxes.Add(dropDownList); AsyncPostBackTrigger trigger = new AsyncPostBackTrigger() { ControlID = dropDownList.UniqueID, EventName = "SelectedIndexChanged" }; this.StandardOptionsUpdatePanel.Triggers.Add(trigger); } } void QuotePropertyDropDown_SelectedIndexChanged(object sender, EventArgs e) { QuoteCostLabel.Text = QuoteCost.ToString(); }

  • How to make a ToolStripComboBox to fill all the space available on a ToolStrip?

    - by Ivan
    A ToolStripComboBox is placed after a ToolStripButton and is folowed by another one, which is right-aligned. How do I best set up the ToolStripComboBox to always adjust its length to fill all the space available between the preceeding and the folowing ToolStripButtons? In past I used to handle a parent resize event, calculate the new length to set based on neighboring elements coordinates and setting the new size. But now, as I am developing a new application, I wonder if there is no better way.

  • .NET and C# Exceptions. What is it reasonable to catch.

    - by djna
    Disclaimer, I'm from a Java background. I don't do much C#. There's a great deal of transfer between the two worlds, but of course there are differences and one is in the way Exceptions tend to be thought about. I recently answered a C# question suggesting that under some circstances it's reasonable to do this: try { some work } catch (Exeption e) { commonExceptionHandler(); } (The reasons why are immaterial). I got a response that I don't quite understand: until .NET 4.0, it's very bad to catch Exception. It means you catch various low-level fatal errors and so disguise bugs. It also means that in the event of some kind of corruption that triggers such an exception, any open finally blocks on the stack will be executed, so even if the callExceptionReporter fuunction tries to log and quit, it may not even get to that point (the finally blocks may throw again, or cause more corruption, or delete something important from the disk or database). May I'm more confused than I realise, but I don't agree with some of that. Please would other folks comment. I understand that there are many low level Exceptions we don't want to swallow. My commonExceptionHandler() function could reasonably rethrow those. This seems consistent with this answer to a related question. Which does say "Depending on your context it can be acceptable to use catch(...), providing the exception is re-thrown." So I conclude using catch (Exception ) is not always evil, silently swallowing certain exceptions is. The phrase "Until .NET 4 it is very bad to Catch Exception" What changes in .NET 4? IS this a reference to AggregateException, which may give us some new things to do with exceptions we catch, but I don't think changes the fundamental "don't swallow" rule. The next phrase really bothers be. Can this be right? It also means that in the event of some kind of corruption that triggers such an exception, any open finally blocks on the stack will be executed (the finally blocks may throw again, or cause more corruption, or delete something important from the disk or database) My understanding is that if some low level code had lowLevelMethod() { try { lowestLevelMethod(); } finally { some really important stuff } } and in my code I call lowLevel(); try { lowLevel() } catch (Exception e) { exception handling and maybe rethrowing } Whether or not I catch Exception this has no effect whatever on the excution of the finally block. By the time we leave lowLevelMethod() the finally has already run. If the finally is going to do any of the bad things, such as corrupt my disk, then it will do so. My catching the Exception made no difference. If It reaches my Exception block I need to do the right thing, but I can't be the cause of dmis-executing finallys

  • mootools fx working except in ie9

    - by Craig
    This is my first attempt with Mootools, so I welcome a critique of the code. I have a dynamic list of images that expand on the 'click" event and contract on the 'mouseout' event. The code works fine in all browsers (FF, Safari, Chrome, even the smartphones) but not in IE9 (JS is enabled) Anyone with similar problem or solution? I plan to use a lightbox effect, downloading a larger & clearer image to the center of the page, instead of just resizing a small image. However, I am hesitant to attempt this, if there is problems with IE9. I have coded three image sizes with the upload commit, so the larger image is available for the lightbox, but, I don't see anything in mootools for a lightbox, or am I missing it? $i = 0; while($i < count($validate)) { <div class="validate"> <div class="validate_image_<?php echo $validate[$i]['validate_type']; ?>"> <div class="validate_image" id="validate_image_wrapper_<?php echo $i; ?>"> <?php if ($validate[$i]['validate_image_filename'] != '') { if (file_exists(UPLOAD_DIR . 'validate_image/' . str_replace('.', '_medium.', $validate[$i]['validate_image_filename']))) { echo '<img src="' . UPLOAD_URL . 'validate_image/' . str_replace('.', '_medium.', $validate[$i]['validate_image_filename']) . '" alt="Listing Image" />'; } else { echo '<img src="' . UPLOAD_URL . 'validate_image/' . str_replace('.', '_large.', $validate[$i]['validate_image_filename']) . '" alt="Listing image" />'; } } else { ?> <img src="/images/no_image_posted_validate.png" alt="no image posted" /> <?php } ?> </div> ... remainder of HTML display code function setupEnlargeImage() { window.myFx = new Fx({ duration: 200, transition: Fx.Transitions.Sine.easeOut }); $$('.validate_image').addEvent('click', function() { window.selectedImage = this.id; myFx.start(1,2.0); }); $$('.validate_image').addEvent('mouseout', function() { window.selectedImage = this.id; myFx.start(1.0,1); }); myFx.set = function(value) { var style = "scale(" + (value) + ")"; $(window.selectedImage).setStyles({ "-webkit-transform": style, "-moz-transform": style, "-o-transform": style, "-ms-transform": style, transform: style }); } }
