  • jquery how to access the an xml node by index?

    - by DS
    Hi, say I've an xml returned from server like this: <persons> <person> <firstname>Jon</firstname> </person> <person> <firstname>Jack</firstname> </person> <person> <firstname>James</firstname> </person> </persons> If I want to access the 3rd firstname node (passed dynamically and stored in i, assumed to be 3 here), how do I do that? My weird attempt follows: var i=3; $(xml).find('firstname').each(function(idx){ if (idx==i) alert($(this).text()); }); It does fetch me the right content... but it just feels wrong to me especially the looping part. Basically I'm looping through the whole tree using .each()! Is there any better approach than this? Something that'd take me to the nth node directly like: alert( $(xml).find('firstname')[idx].text() ); // where idx=n I'm new to jquery so please excuse my jquery coding approach.

  • IE and replaceWith not preserving radio button state

    - by copelco
    Hello, I've run into an issue regarding replaceWith not maintaining the state of a moved radio button input. I've prepared a simple example illustrating this issue. This works in FF and Chrome, but not IE. Is there a way around this? Thanks! jsbin: http://jsbin.com/unola4/2 code: <html> <head> <script class="jsbin" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script> <title>IE replaceWith issue</title> <script type='text/javascript'> $(function(){ $('a').click(function(e) { e.preventDefault(); $('#temp').replaceWith($('#window').children()); }); }); </script> </head> <body> <a href='#'>run replaceWith</a> <p>Select a radio button and then click "run replaceWith".

  • xhtml validator

    - by lolalola
    Hi, why w3 validator show error? "Line 5, Column 7: end tag for "head" which is not finished </head> Most likely, you nested tags and closed them in the wrong order. For example <p><em>...</p> is not acceptable, as <em> must be closed before <p>. Acceptable nesting is: <p><em>...</em></p> Another possibility is that you used an element which requires a child element that you did not include. Hence the parent element is "not finished", not complete. For instance, in HTML the <head> element must contain a <title> child element, lists require appropriate list items (<ul> and <ol> require <li>; <dl> requires <dt> and <dd>), and so on.

  • Is it a good practice for a .js file to rely on variables declared in the including html

    - by Bozho
    In short: <script type="text/javascript"> var root = '${config.root}'; var userLanguage = '${config.language}'; var userTimezone = '${config.timezone}'; </script> <script type="text/javascript" src="js/scripts.js"></script> And then, in scripts.js, rely on these variables: if (userLanguage == 'en') { .. } The ${..} is simply a placeholder for a value in the script that generates the page. It can be php, jsp, asp, whatever. The point is - it is dynamic, and hence it can't be part of the .js file (which is static). So, is it OK for the static javascript file to rely on these externally defined configuration variables? (they are mainly configuration, of course). Or is it preferred to make the .js file be served dynamically as well (i.e. make it a .php / .jsp, with the proper Content-Type), and have these values defined in there.

  • Named Range Breaks Code

    - by Daniel
    I have one workbook with several sheets. I populate the listboxes (pulling static data from cells) on the 2nd sheet, click a button and it runs fine. When I populate the listboxes with a named range, the listbox populates the way I want, but I get an error because the code thinks that I didn't select anything in the listbox, even though I did. So it passes through "" instead of "title". Is this a common issue? The named range isn't a problem because it passes through the data to the listbox and I know it's selecting data because as soon as the listbox loses focus, it spits out the contents of the cell into cell A1. What's even stranger is that I have the contents of the listbox set to Msg1. So A1 gets populated with Msg1 (what I actually selected in the listbox). But when I try and use Msg1 in the code, it tells me that Msg1 is "". Again, this only happens when I use the dynamic named range, not with static data in cells K1:K9. Private Function strEndSQL1 As String Dim strSQL As String strSQL = "" 'Create SQL statement strSQL = "FROM (SELECT * FROM dbo.Filter WHERE ID = " & TextBox1.Text & " And Source IN (" & Msg1 & ")) a FULL OUTER JOIN " strSQL = strSQL & "(SELECT * FROM dbo.Filters WHERE ID = " & TextBox2.Text & " And Source IN (" & Msg1 & ")) b " strSQL = strSQL & "ON a.Group = b.Group strEndSQL = strSQL End Function

  • User switching without logging off

    - by mrh1967
    We need to switch users without logging off so we can remotely administrate a PC running with a limited user that will disconnect from the VPN if the user logs off. I've got this working by killing the explorer process and then running explorer.exe with the administrator user credentials as the following code shows: private void btnOk_Click(object sender, EventArgs e) { IntPtr tokenHandle = new IntPtr(0); if (LogonUser("administrator", Environment.UserDomainName, txtPassword.Text, 3, 0, ref tokenHandle)) { ProcessStartInfo psi = new ProcessStartInfo(@"C:\Windows\explorer.exe"); psi.UserName = "administrator"; char[] pword = txtPassword.Text.ToCharArray(); psi.Password = new System.Security.SecureString(); foreach (char c in pword) { psi.Password.AppendChar(c); } psi.UseShellExecute = false; psi.LoadUserProfile = true; restartExplorer(psi); this.Close(); } else { MessageBox.Show("Wrong password", "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); } } private void restartExplorer(ProcessStartInfo psi) { Process[] procs = System.Diagnostics.Process.GetProcesses(); foreach (Process p in procs) { if (p.ProcessName == "explorer") { p.Kill(); break; } } System.Diagnostics.Process.Start(psi); } [DllImport("advapi32.dll", SetLastError = true)] public extern static bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); This code and similar code that does the same but makes the ProcessStartInfo for the limited user works perfectly and allows changing between the limited and administrator accounts without disconnecting the VPN but it has one problem - If we use this to change to the administrator user, make some changes to the system, then change back to the limited user all works ok until the limited user logs off when a blank desktop is displayed until CTRL-ALT-DEL is pressed and the user is logged off again. Because we block CTRL-ALT-DEL the PC effectively hangs until it is powered off. Does anyone know how to stop this from happening so we can change users without the PC hanging when they log off?

  • Iphone: XML image problem

    - by avanadra
    Hi! I have a question about parsing XML and putting it into a table. I parsed the following elements from a RSS feed : title, dc:creator and enclosure url (= an image). The parsing is working, i can see everything showing up in the console. But when i try to load everything into the tablecell, everything shows up except for the image. So i figured that the problem must be in the CellForRowatIndexPath method in the RootViewController.m ( or in the TableCell.m) What am i doing wrong? Please help! Ive been struggling for days with this and just cant seem to figure it out! Heres the CellForRowatIndexPath: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; WerkTableCell *cell = (WerkTableCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"WerkCell" owner:self options:nil]; cell =self.werkCell; } // Configure the cell. NSMutableArray *cont= [xmlcont items];// is niet in tablevb v. PS ItemData *current =[cont objectAtIndex:indexPath.row]; cell.titelLabel.text = [current titel]; cell.makerLabel.text = [current maker]; cell.thumbImage.image = [UIImage imageNamed:[current image]]; return cell; }

  • Appended content using jQuery 'append' is not submitted?

    - by YourMomzThaBomb
    I'm new to jQuery so this may be a real simple answer. I have a ASP.NET project that I'm trying to dynamically add content to a span element by typing into a text box and clicking a button. Sounds simple right? Well, I can get the content to added, but when the form is submitted the span element is still empty? Why is the new data not submitted? What step am I missing? Please help. Here's some sample code: < span id="tagContainer" runat="server"< /span < input type="text" name="tag" id="tag" / < input type="button" name="AddTag" value="Add" class="button" onclick="addTag();" / function addTag() {    if ($("#tag").val() != "") {       $("#tagContainer").append('$("#tag").val()');       $("#tag").val("");    } }

  • Creating 1 page PDF of iPad Screen view - How?

    - by user314695
    Hi All, I've asked this question on a couple other forums and have had zero response, so I'm hoping someone here can help point me in the right direction. I have a pretty simple one screen application for my work. It's basically just a recreation of a 1 page paper report that has a company logo, some labels, a few text boxes and a scroll text box for the report. I need to be able to fill out the report then click a button to save it in a graphical form so I can fax, print or email it later. Currently, I'm just programmatically taking a screen capture and saving it to the photo's library (default for screen capture). Then I can just email it from photo's. This works ok, but is kind of hacky, at best. I've read through the new iPad 3.2 guide for creating PDF's (apparently it's supposed to be much easier than before) but I can not get it to work and I've spent countless hours on it now. I'm hoping someone has the answer for me. Alternatively, if anyone knows how I can redirect where the screen capture is stored (default is in the photo album) then maybe I can make that function work. If I could redirect the screen capture to store in my applications document folder, then I can use MFMailCompose to attach it to an email. Lastly, on a side note, does anyone know of a good way to capture a digital signature via touch. For instance, I'd love to have my users be able to just sign their name via touch at the bottom of the document before I convert to PDF or take a screen capture. Thanks in advance for your help. -Ray

  • Google Sites API - File Cabinets: Spaces and extension separator (.) are removed from file names

    - by user1299447
    We have a series of internal reports that we update regularly from our internal databases. We built an application in C# that uploads these reports to a Google Site. Everything works fine, except that the name of the file shown to the final user in the File Cabinet does not include the original spaces nor the extension separator (.) For example, Stock per warehouse.pdf is shown as : Stockperwarehousepdf Below is a simplified version of the code. private AtomEntry UploadAttachment(string filename, AtomEntry parent, string title, string description) { SiteEntry entry = new SiteEntry(); AtomCategory category = new AtomCategory(SitesService.ATTACHMENT_TERM, SitesService.KIND_SCHEME); category.Label = "attachment"; entry.Categories.Add(category); AtomLink parentLink = new AtomLink(AtomLink.ATOM_TYPE, SitesService.PARENT_REL); parentLink.HRef = parent.SelfUri; entry.Links.Add(parentLink); entry.MediaSource = new MediaFileSource(filename, MediaFileSource.GetContentTypeForFileName(filename)); entry.Content.Type = MediaFileSource.GetContentTypeForFileName(filename); entry.Title.Text= title; entry.Summary.Text = description; AtomEntry newEntry = null; newEntry = service.Insert(new Uri(makeFeedUri("content")), entry); } The key line is where the MediaFileSource object is created. Any idea of what we are missing? I've tried all sort of changes :(

  • Alignment for image display on hover works only in IE7?

  • How can I prevent the scaling of a UIWebview's content after reorientation?

    - by frankhermes
    I'm building an iOS 5/6 app that has a UIWebView. It loads some HTML that I have embedded in my app. Now when I rotate my device, the WebView changes its size (as I want it to fill the entire width of the screen). And then it gets weird: some content gets scaled up and some content doesn't get scaled up. See this image with some example text in it: As you can see, the header (H6) stays the same, while the paragraph gets scaled up. Does anybody have an idea how to prevent this? I want the html to look the same in landscape as it does in portrait mode. I've tried setting the viewport scaling to 1: <meta name="viewport" content="initial-scale=1.0,max-scale=1.0"> but that doesn't help. The body's font-size style is set to 14px, but changing that to 14pt or a percentage also made no difference. Setting the width of the body to 100% also didn't help. Strangely, removing the line break (<br/>) that's in the text fixes it but I need line breaks to be in there so that's no solution. The only thing that does work is reloading the UIWebView's content after an orientation change, but that doesn't prevent it from looking wrong during rotation, and it resets any scrolling that the user may have done. Any ideas?

  • Python: Calling method A from class A within class B?

    - by Tommo
    There are a number of questions that are similar to this, but none of the answers hits the spot - so please bear with me. I am trying my hardest to learn OOP using Python, but i keep running into errors (like this one) which just make me think this is all pointless and it would be easier to just use methods. Here is my code: class TheGUI(wx.Frame): def __init__(self, title, size): wx.Frame.__init__(self, None, 1, title, size=size) # The GUI is made ... textbox.TextCtrl(panel1, 1, pos=(67,7), size=(150, 20)) button1.Bind(wx.EVT_BUTTON, self.button1Click) self.Show(True) def button1Click(self, event): #It needs to do the LoadThread function! class WebParser: def LoadThread(self, thread_id): #It needs to get the contents of textbox! TheGUI = TheGUI("Text RPG", (500,500)) TheParser = WebParser TheApp.MainLoop() So the problem i am having is that the GUI class needs to use a function that is in the WebParser class, and the WebParser class needs to get text from a textbox that exists in the GUI class. I know i could do this by passing the objects around as parameters, but that seems utterly pointless, there must be a more logical way to do this that doesn't using classes seem so pointless? Thanks in advance!

  • Creating UIButtons

    - by Ralphonzo
    During loadView I am creating 20 UIButtons that I would like to change the title text of depending on the state of a UIPageControl. I have a pre-save plist that is loaded into a NSArray called arrChars on the event of the current page changing, I set the buttons titles to their relevant text title from the array. The code that does this is: for (int i = 1; i < (ButtonsPerPage + 1); i++) { UIButton *uButton = (UIButton *)[self.view viewWithTag:i]; if(iPage == 1) { iArrPos = (i - 1); } else { iArrPos = (iPage * ButtonsPerPage) + (i - 1); } [uButton setAlpha:0]; NSLog(@"Trying: %d of %d", iArrPos, [self.arrChars count]); if (iArrPos >= [self.arrChars count]) { [uButton setTitle: @"" forState: UIControlStateNormal]; } else { NSString *value = [[NSString alloc] initWithFormat:@"%@", [self.arrChars objectAtIndex:iArrPos]]; NSLog(@"%@", value); [uButton setTitle: [[NSString stringWithFormat:@"%@", value] forState: UIControlStateNormal]; [value release]; //////Have tried: //////[uButton setTitle: value forState: UIControlStateNormal]; //////Have also tried: //////[uButton setTitle: [self.arrChars objectAtIndex:iArrPos] forState: UIControlStateNormal]; //////Have also also tried: //////[uButton setTitle: [[self.arrChars objectAtIndex:iArrPos] autorelease] forState: UIControlStateNormal]; } [uButton setAlpha:1]; } When setting the Title of a button it does not appear to be autoreleasing the previous title and the allocation goes up and up. What am I doing wrong? I have been told before that tracking things by allocations is a bad way to chase leaks because as far as I can see, the object is not leaking in Instruments but my total living allocations continue to climb until I get a memory warning. If there is a better way to track there I would love to know.

  • Enabling all buttons in a repeater except for the clicked one

    - by NewAmbition
    I have a Repeater Control with various buttons in it. When the button gets clicked, it needs to disable itself so it cant be clicked again. Working. However, when I click that button, it needs to enable any other button but it. So, When I click on it, it needs to disable. When I click on another one, the previous button must enable, and that one must disable. So for I've tried: Button btnLoad = (Button)e.Item.FindControl("btnLoad"); foreach (Button b in e.Item.Controls.OfType<Button>().Select(c => c).Where(b => b != btnLoad)) { b.Enabled = true; } btnLoad.Text = "Currently Viewing"; btnLoad.Enabled = false; But it isnt working. Depending on where I put it, its either leaving all the buttons enabled (But still changing its text), or not doing anything at all. What do I need to do to make this work?

  • rendering a TextView in a Bitmap for an android widget

    - by foke
    I'm building a widget which displays some text. By widget I mean the kind which lies on the desktop. The problem is that I want to change text's font at runtime. There is several textview I would like, at runtime, to set the first as bold, the second blue and italic for example, etc. I came up with this : TextView tv = new TextView(context); tv.setText(stringToDisplay); tv.setTextColor(0xa00050ff); // example tv.setTextSize(30); // example Bitmap b = loadBitmapFromView(tv); updateViews.setImageViewBitmap(R.id.id_of_the_imageview, b); with private static Bitmap loadBitmapFromView(View v) { Bitmap b = Bitmap.createBitmap(v.getLayoutParams().width, v.getLayoutParams().height, Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height); v.draw(c); return b; } but it wont work (NullPointerException on first line of loadBitmap), until I replace v.getLayoutParams().width, v.getLayoutParams().height by fixed sizes like 250, 50 Bitmap b = Bitmap.createBitmap(250, 50, Bitmap.Config.ARGB_8888); // ... v.layout(0, 0, 250, 50); But that's not a good solution ... so I tried this : LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View row = li.inflate(R.layout.widget_text, null); TextView tv = (TextView) row.findViewById(R.id.id_of_the_textview); widget_text being a layout similar to the displayed one but with TextViews instead of ImageViews, in the hope to get some size information out of it .. but it's not working and I get this exception : 01-02 17:35:06.001: ERROR/AndroidRuntime(11025): Caused by: java.lang.IllegalArgumentException: width and height must be > 0 on the call to Bitmap.createBitmap() so, someone could point me in the right direction?

  • How do I pass a value to a method in Objective C

    - by user268124
    I'm new to Obj-C and I have run in to a very, very basic mental block that's making me feel a little stupid. I want to pass a variable from one method to another in an purely objective-C way. So far I'm stuck and have resorted to writing it in C. In C it goes as follows; //detect the change in the segmented switch so we can; change text - (IBAction)switchChanged:(id)sender { NSLog(@"Switch change detected"); //grab the info from the sender UISegmentedControl *selector = sender; //grab the selected segment info from selector. This returns a 0 or a 1. int selectorIndex = [selector selectedSegmentIndex]; changeText (selectorIndex); } int changeText (int selectorPosition) { NSLog(@"changeText received a value. Selector position is %d", selectorPosition); //Idea is to receive a value from the segmented controler and change the screen text accordingly return 0; } This works perfectly well, but I want to learn how to do this with objects and messages. How would I rewrite these two methods to do this? Cheers Rich

  • Google Maps + PODSCMS

    - by Sharath
    Hi, I have a column called 'location' in a POD which I have created. I was looking to write a input helper where I display a Google Map and the user clicks on a location, and I capture that into this column. This is what I am trying to do <div class="form pick <?php echo $location; ?>"> <script src="http://maps.google.com/maps?file=api&v=1&key=<key_here>" type="text/javascript"></script> <div id="map" style="width:500; height:500"> <script type="text/javascript"> map=new GMap(document.getElementById("map")); map.centerAndZoom(new GPoint(77.595062,13.043359),6); map.setUIToDefault(); </script> </div> </div> But I am getting a number of errors from google maps API. Any idea how i can get this helper in there?

  • Adding fields until screen is full

    - by Eric
    For the sake of this question, let us suppose that I want a row of buttons. I want to put as many buttons in that row as I can fit on the screen, but no more. In other words, as long as a prospective button will not be cut off or have its text shortened, add it. It seems that I should be able to do something like: HorizontalFieldManager hfm = new HorizontalFieldManager(); int remainingWidth = Display.getWidth(); int i =0; while(true) { ButtonField bf = new ButtonField("B " + i); remainingWidth -= bf.getWidth(); if(remainingWidth<0) break; hfm.add(bf); i++; } add(hfm); But this doesn't work. bf.getWidth() is always 0. I suspect that this is because the button has not yet been laid out when I query for the width. So, perhaps I could just make sure the buttons are always the same size. But this won't work for a few reasons: Different BB platforms have different looks for buttons and text that will fit on a button on a Curve won't fit on a button on a Storm. 3rd party themes may change the look of buttons, so I can't even count on buttons being a certain size on a certain platform. Is there no way for me to actually check the remaining space before adding a button? It feels like a fairly useful feature; am I just missing something?
