• How to know when a pop-down menu needs to be closed

  - by Pieter

  I'm experimenting with pop-down menus (inside floating DIVs). Making them appear with onmouseover attributes is no problem, but I'm not sure how I can make the menu close properly. I figured the best way to know when to close the menu is wait until the mouse is no longer hovering over the HTML element that called the menu or the menu itself, then wait one second, and then close the menu. Is my idea something that can be implemented, perhaps with some jQuery? Or is there a better and more efficient alternative?

• How to get the Focus on one of Buttons of JQuery Dialog on ASP.NET MVC page?

  - by Rita

  Hi I have an ASP.NET MVC page(Registration). On loading the page, i am calling Jquery Dialog with Agree and Disagree buttons on that Dialog. 1). How to set the focus to Agree button by default? 2). How to disable the X (Close) Mark that is on Top right corner? (So that i don't want the user to close that dialog simply). Code: $("#dialog-confirm").dialog({ closeOnEscape: false, autoOpen: <%= ViewData["autoOpen"] %>, height: 400, width: 550, modal: true, buttons: { 'Disagree': function() { location.href = "/"; }, 'Agree': function() { $(this).dialog('close'); $(this).focus(); } }, beforeclose: function(event, ui) { var i = event.target.id; var j = 0; } }); Appreciate your responses. Thanks

• window.beforeunload called twice in Firefox - how to get around this?

  - by Zarkonnen

  I'm creating a popup window that has a beforeunload handler installed. When the "Close" file menu item is used to close the popup, the beforeunload handler is called twice, resulting in two "Are you sure you want to close this window?" messages appearing. This is a bug with Firefox, and I've reported it here, but I still would like a way to prevent this from happening. Can you think of a sane way of detecting double beforeunload to prevent the double message problem? The problem is that Firefox doesn't tell me which button in the dialog the user elected to click - OK or cancel.

• SubSonic: MySqlDataReader closes connection.

  - by SchlaWiener

  I am using SubSonic 2.1 and entcountered a problem while executing a Transaction with SharedDbConnectionScope and TransactionScope. The problem is that in the obj.Save() method I get an "The connection must be valid and open" exception I tracked down the problem to this line: // Loads a SubSonic ActiveRecord object User user = new User(User.Columns.Username, "John Doe"); in this Constructor of the User class a method "LoadParam" is called which eventually does if (rdr != null) rdr.Close(); It looks like the rdr.Close() implicitly closes my connection which is fine when using the AutomaticConnection. But during a transaction it is usally not a good idea to close the connection :-) My Question is if this is by design or if it's an error in the MySqlDataReader.

• IE6 not rendering the page

  - by JX

  I have a web page which consists of a few component pages. When a user requests the page, the server assembles its component pages into the main page and sends it back to the browser. When there is an update on the component page, IE6 browser cannot see the updated content. However, IE7 and Firefox are fine. Checking with Fiddler, the http response returns 200, If-Modified-Since header is the same as the last modified date of the main page, the response raw html also has the updated content. It seems that IE6 browser abandons the rendering of the page because If-Modified-Since is the same as the last modified date of the main page. Does anyone know how to overcome this issue in IE6?

• jQuery iframe overlay with flash closing issue

  - by Ryan Max

  Hello, I have a site that has a jQuery overlay, which contains an iframe, which pulls in another site that has flash in it. One of the buttons in the flash has editable parameters in xml, and I can change where the link points to. I want this button to close the overlay, but I can't quite figure out how to get it to work. I have tried the following: closeSection(); and parent.closeSection(); and window.parent.closeSection(); None of which work. Though the last two come close. They seem to close the flash, as the iframe just goes blank. Can anyone steer me in the right direction?

• How to catch FTP errors? e.g., socket.error: [Errno 10060]

  - by Johnson

  I'm using the ftplib module to upload files: files = [ a.txt , b.txt , c.txt ] s = ftplib.FTP(ftp_server , ftp_user , ftp_pw) # Connect to FTP for i in range(len(files)): f = open(files[i], 'rb') stor = 'stor ' + files[i] s.storbinary(stor, f) f.close() # close file s.quit() # close ftp How do I catch the following error? socket.error: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond And what other errors are common when using the FTP module that I should also catch? Thanks for any help or pointers.

• Working with images in asp.net MVC ViewMasterPage in design mode

  - by amit.codename13

  While designing a master page i am adding a number of images to it. I have an image tag inside the master page, <img src="../../Content/Images/img19.jpg" class="profileImage" /> When i run my app, the image doesn't show up in the browser because the src path in the page that browser gets is same as in the master page. ie. "../../Content/Images/img19.jpg" But it should have been "Content/Images/img19.jpg" If i correct the src path in master page as <img src="Content/Images/img19.jpg" class="profileImage" /> Then I can see the image in the browser but not in design mode. Any help is appreciated.

• Animated Gif in form using C#

  - by Rabin

  In my project, whenever a long process in being executed, a small form is displayed with a small animated gif file. I used this.Show() to open the form and this.Close() to close the form. Following is the code that I use. public partial class PlzWaitMessage : Form { public PlzWaitMessage() { InitializeComponent(); } public void ShowSpalshSceen() { this.Show(); Application.DoEvents(); } public void CloseSpalshScreen() { this.Close(); } } When the form opens, the image file do not immediately start animating. And when it does animate, the process is usually complete or very near completion which renders the animation useless. Is there a way I can have the gif animate as soon as I load the form?

• What could cause a button on a UIActionSheet to "miss" on touches?

  - by Alex Gosselin

  I have a UIActionSheet as follows: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:[NSString stringWithFormat: @"Cancel New %@? Changes will be lost.", [creator propertyName]] delegate:self cancelButtonTitle:@"Stay Here" destructiveButtonTitle:@"Discard and Close" otherButtonTitles:@"Save and Close", nil]; [sheet showInView:self.view]; [sheet release]; It creates the action sheet, The buttons display, the Destructive button is on top, cancel button is on the bottom, other button (save and close) shows up in the middle, the top two buttons, (destructive and other) work fine, but the bottom button has a gap, so it is farther down than the other buttons. For some reason though, in order to press the button I need to touch where it would be if there was no gap. Touching the actual button doesn't work. Sorry if this isn't super clear, has anyone encountered something like this? I don't like to whip out the "I found a bug" card too fast, maybe I'm doing something wrong here.

• 2D World design question

  - by Maciek

  I'm facing a problem which is probably extremely common in game-design. Let's assume that we've got a 2D world The world's size is M x N rect The world may contain some items in it The items have (x,y) coords The world can be browsed via a window that is physically (m x n) large. The browser window can be zoomed in / out The browser window can be panned up/down + left right, while in the extents of the world's rect. How should I go about implementing this? I'm especially concerned about the browser window. Can anyone recommend any good reads ? This is not a homework - it's more of a task which I've set myself to complete.

• load a pickle file from a zipfile

  - by eric.frederich

  For some reason I cannot get cPickle.load to work on the file-type object returned by ZipFile.open(). If I call read() on the file-type object returned by ZipFile.open() I can use cPickle.loads though. Example .... import zipfile import cPickle # the data we want to store some_data = {1: 'one', 2: 'two', 3: 'three'} # # create a zipped pickle file # zf = zipfile.ZipFile('zipped_pickle.zip', 'w', zipfile.ZIP_DEFLATED) zf.writestr('data.pkl', cPickle.dumps(some_data)) zf.close() # # cPickle.loads works # zf = zipfile.ZipFile('zipped_pickle.zip', 'r') sd1 = cPickle.loads(zf.open('data.pkl').read()) zf.close() # # cPickle.load doesn't work # zf = zipfile.ZipFile('zipped_pickle.zip', 'r') sd2 = cPickle.load(zf.open('data.pkl')) zf.close() Note: I don't want to zip just the pickle file but many files of other types. This is just an example.

• Rails redirect_to jQTouch site does not work as expected

  - by tilthouse

  I have a Rails app with a jQTouch mobile site that is displayed if the user goes to m.blah.com. First, I detect the browser, then to a redirect_to m.blah.com if it's an iphone, etc. All well and good. When I use desktop Safari, this all works exactly right. However, when I use an actual iPhone or the Apple iPhone Simulator, it does not. The mobile site appears to load without the browser actually doing the redirect. The URL in the browser is still www. I am wondering if this behavior is due to Mobile Safari, or if it is somehow jQTouch trying to load the page with AJAX, not a reload (which is odd as jQTouch hasn't been loaded at all before the redirect). Any ideas?

• Sketchflow component target parent state

  - by user186106

  Hi, I'm using Sketchflow in Expression Blend 4 RC (although this is relevant to Blend 3 too). I have a screen with a datagrid on it (MainScreen) and there's a "New" button. I have a component screen that has a generic form (GenericForm) and a "Save and close" button. I have two states on MainScreen: State1 (and default): GenericForm visibility set to Hidden State2: GenericForm visibility set to Visible The "New" button on MainScreen has: Active State = State2, meaning when the "New" button is pressed, it changes the state of MainScreen to State2 (where the GenericForm component is visible). My problem is that I cannot link the "Save and close" button on GenericForm to State1 on MainScreen. In effect I would like to be able to press "Save and close" and for the MainScreen to set its state to State1. Any ideas?

• SharePoint 2010 is forcing me to safe PDF when opening from doc library

  - by Tobias Funke

  I have a document library with a PDF file. Whenever I click on the PDF file, I am prompted to save the file. I do not get the option of opening the file, I am forced to save it. What I want is for the PDF file to open, either in the browser or in a separate Adobe Reader window, depending on the Adobe Reader settings. I'm pretty sure SharePoint is responsible for this behavior, because if I put the PDF on my hard drive, then create a HTML file with a link to the file, it opens in the browser when I click on it. Please note: I looked at this question and did not help. I don't care if the PDF opens in the browser or in a separate Adobe Reader window, I just want it to open.

• Preload Images with javascript

  - by user271619

  Here is my preload script: <script type="text/javascript"> Image_1 = new Image(1,1); Image_1.src = "images/sprites.png"; </script> And it works fine. I can see in the headers the image loading. Here's my question. Even though I have preloaded sprites.png, I notice that when I go to a page on my site that simply displays that entire image, the headers tell me my browser is requesting the server to send the image again. I'm hoping to not sound too naive. But, why would the browser request the image when I preloaded it earlier? Are there other reasons the browser would need to re-request? Also, I put the dimensions as Image(1,1). Sometimes I don't know the dimensions, as that image gets updated from time to time. Maybe that's a reason?

• Grouping with operands question

  - by Filip

  I have a table: mysql> desc kursy_bid; +-----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+-------------+------+-----+---------+-------+ | datetime | datetime | NO | PRI | NULL | | | currency | varchar(6) | NO | PRI | NULL | | | value | varchar(10) | YES | | NULL | | +-----------+-------------+------+-----+---------+-------+ 3 rows in set (0.01 sec) I would like to select some rows from a table, grouped by some time interval (can be one day) where I will have the first row and the last row of the group, the max(value) and min(value). I tried: select datetime, (select value order by datetime asc limit 1) open, (select value order by datetime desc limit 1) close, max(value), min(value) from kursy_bid_test where datetime > '2009-09-14 00:00:00' and currency = 'eurpln' group by month(datetime), day(datetime), hour(datetime); but the output is: | open | close | datetime | max(value) | min(value) | +--------+--------+---------------------+------------+------------+ | 1.4581 | 1.4581 | 2009-09-14 00:00:05 | 4.1712 | 1.4581 | | 1.4581 | 1.4581 | 2009-09-14 01:00:01 | 1.4581 | 1.4581 | As you see open and close is the same (but they shouldn't be). What should be the query to do what I want?

• Custom buttons in MS-Access 2k7

  - by terence6

  I'm adding some custom buttons to my forms in MS Access, but somehow I can't make them work. In buttons properties Event tab I've changed 'On Click' event to call 'Event procedure'. Then in VBasic I'm selecting my button and from what I know this code should give me prompt, and if Yos is selected the form should close. But when I click my buttons simply nothing happens. Am I doing something wrong ? Option Compare Database Option Explicit Private Sub cmdQuitApp_Click() If MsgBox("Are you sure you want to close the form?", vbYesNo + vbQuestion + vbInformation, "Clasing the form.") = vbYes Then DoCmd.Close End If End Sub

• Can you use PHP libcurl to pull files from server A to server B?

  - by Majid

  Hi, cURL and libcurl let you do things you normally do with a browser, right? Like, as if you have a jini sit inside a server and fire up a browser and do stuff. Ok then. I need a script to sit on server B, and click on download links on a server A and download files (from server A to server B). I am new to curl, and not sure if all I need is to issue a simple get or something else. I know that Content-disposition header forces the browser to save the document. Does it have the same effect on libcurl too? If it does, I'll make my serving script on server A send that header, and then serve the file. Any advice is appreciated. Thanks

• Shutting Down SSH Tunnel in Paramiko Programatically

  - by PlaidFan

  We are attempting to use the paramiko module for creating SSH tunnels on demand to arbitrary servers for purposes of querying remote databases. We attempted to use the forward.py demo that ships with paramiko but the big limitation is there does not seem to be an easy way to close an SSH tunnel and the SSH connection once the socket server is started up. The limitation we have is that we cannot activate this from a shell and then kill the shell manually to stop the listner. We need to open the SSH connection, tunnel, perform some actions through the tunnel, close the tunnel, and close the SSH connection within python. I've seen references to a server.shutdown() method but it isn't clear how to implement it correctly. Any help would be greatly appreciated...

• java.io.IOException: Invalid argument

  - by Luixv

  Hi I have a web application running in cluster mode with a load balancer. It consists in two tomcats (T1, and T2) addressing only one DB. T2 is nfs mounted to T1. This is the only dofference between both nodes. I have a java method generating some files. If the request runs on T1 there is no problem but if the request is running on node 2 I get an exception as follows: java.io.IOException: Invalid argument at java.io.FileOutputStream.close0(Native Method) at java.io.FileOutputStream.close(FileOutputStream.java:279) The corresponding code is as follows: for (int i = 0; i < dataFileList.size(); i++) { outputFileName = outputFolder + fileNameList.get(i); FileOutputStream fileOut = new FileOutputStream(outputFileName); fileOut.write(dataFileList.get(i), 0, dataFileList.get(i).length); fileOut.flush(); fileOut.close(); } The exception appears at the fileOut.close() Any hint?

• How can I detect when a file download has completed in ASP.NET?
