• iPhone - Custom Tab Icons, Remove Highlight

  - by user269737

  I am creating a custom tab bar for my iPhone app and I need to change the images. I have changed the actual tab bar background, but I need to know how to add custom images for the icons and their respective "selected" icons. I also need to remove the square highlight that is default. Pretty much, it just needs to be my icons. Also wondering if the images can be coloured or not. I've looked a lot of this, but no one seems to have the solution. Someone please help.

• Python/Tkinter make a custom window

  - by user1435947

  I want to make a window without the top taskbar (that is movable), so there is only thin outline around the GUI box. I also want to add my own 'X' to the box. import Tkinter class Application(Frame): def __init__(self, master=None): Frame.__init__(self, master) self.parent = master ............ def main(): root = Tk() root.attributes('-fullscreen', True) root.geometry('500x250+500+200') app = Application(root) app.parent.configure(background = 'gray32') root.resizable(width=FALSE, height=FALSE) app.mainloop() main() I tried forcing the box to resize after going into fullscreen to remove the taskbar, though box is no longer movable. Any suggestions? [I have seen this thread: Python/Tkinter: Removing/disabling a resizable window's maximize button under Windows The -toolwindow attribute didn't work for me, maybe because I use linux...]

• Err Web Service?

  - by j-t-s

  Hi All I am trying to implement a feature. But I've never had anything to do with "Web Services" before, other than using them. I have a desktop application, and I want that application to be able to sort of "post" some information (i.e. email address, username, user-selected options (just plain text) etc) to an application or "web service" on my ASP.NET web server. Can somebody please guide me in the right direction? How would I accomplish this? Thank you :) Jason

• Closing a window when it's "no longer needed".

  - by Mason Blier

  This is kind of a hard question to describe, and I've searched for about an hour now to no avail. Essentially, picture a small 'flyout' window like the Windows 7 Wireless Control or the Volume Slider from the system tray(notification area). When you click on the icon, the application pops up with focus, and if you click off of it, the window destroys itself. I thought it woudl be easily solved by simply having my window destroy it self when it loses focus (I've been listening for WM_KILLFOCUS), but the problem is, if the icon is clicked, my window does not always get focus. Since this isn't the case, if the user clicks my icon, and then clicks away because it was a mistake (on the desktop say), then how can I set my app to close? I've tried messing with SPY++ but checking the volume control / wireless control apps are proving difficult as they disappear when I try to get their window/process handles. Thanks!

• Generating a beveled edge for a 2D polygon

  - by Metaphile

  I'm trying to programmatically generate beveled edges for geometric polygons. For example, given an array of 4 vertices defining a square, I want to generate something like this. But computing the vertices of the inner shape is baffling me. Simply creating a copy of the original shape and then scaling it down will not produce the desired result most of the time. My algorithm so far involves analyzing adjacent edges (triples of vertices; e.g., the bottom-left, top-left, and top-right vertices of a square). From there, I need to find the angle between them, and then create a vertex somewhere along that angle, depending on how deep I want the bevel to be. And because I don't have much of a math background, that's where I'm stuck. How do I find that center angle? Or is there a much simpler way of attacking this problem?

• How do I get the WinForm Designer to totally ignore a property on a custom control?

  - by Ian Ringrose

  This must be a FAQ, but I can’t find a duplicate question! There are lot of different attributes that control what the WinForm Designer does with properties on a custom control, I am never clear on the one I should use in this case. I am looking for: Designer does not show property in grid Designer does not read value of property Designer does not set property to default value E.g. Designer behaves as if the property was not there. Designer does not complain if it has already done one of the above before the attributes were added (hard!) Background. The code that is giving me the problem is: this.eventListControl.FilterSets = ((SystList<FilterSet>)(resources.GetObject("eventListControl.FilterSets"))); The FilterSets property should never have been touched by the winforms designer; it is now not Serializable and MsDev falls over every time a form that used the eventListControl is changed!

• Activity ignore intent's extra fields

  - by ced

  For example, In an ActivityA there's a button to create an Intent that will start ActivityB in a new task, like this: Intent i = new Intent(this, ActivityB.class); i.setData(Uri.parse("http://www.google.com")); long timestamp = System.currentTimeMillis(); i.putExtra("ts", timestamp); i.addFlag(Intent.FLAG_ACTIVITY_NEW_TASK); Log.d(TAG, "Sending: " + timestamp); startActivity(i); Then in ActivityB's onResume() method, there's this code to check the timestamp: long timestamp = getIntent().getExtras().getLong("ts"); Log.d(TAG, "Receiving: " + timestamp); Now the first time I invoke ActivityB from ActivityA I get the following logs: Sending: 120006000 Receiving: 120006000 Then if I left ActivityB running in the background (by pressing Home button), and start ActivityA then invoke ActivityB again, the following is printed: Sending: 120013000 Receiving: 120006000 It seems although ActivityB is brought to front by the new Intent. The extra field in the intent is being left behind. Is this a bug or an intended behavior?

• How to avoid web server traffic peak resulting from iOS Newsstand app receiving a remote notification?

  - by thomers

  I'm developing an iOS Newsstand app. If it is suspended or not running and connected to a WLAN, Newsstand apps can be triggered by a Push remote notification to download the latest issue (in our case around 100MB) in the background. I'm using Urban Airship for the delivery of the Push broadcast. I'm now worrying about many many iOS devices hitting the web server for one big download more or less at the same time, because I expect the majority of the devices will receive the notification in a very short timeframe. Instead of broadcasts to all devices, should I rather send individual notifications to batches of small groups of devices, spreading them out over a longer period of time? And/or would a CDN like Amazon Cloudfront solve that issue easier/anyway?

• android dialog transparant

  - by Doomic

  It is a simple stupid question, but i cant find any info on the web. I have an android app with a custom dialog. The dialog has the default grey 1px border. But it also has a black border around that grey line. I want to remove the black part. the dialog is made in xml and i call: dialog.setContentView(R.layout.xxxxx); as soon as i do that the black border is there. However the xml has not a background color set. also a transparant color in the xml doesn't helps. if i do not call setcontentview. then a small dialog appears but without a strange border.

• Printing complex widgets in Qt

  - by Jens

  I have a complex widget with tons of different subwidgets, e.g. subclasses of QLabel. I want to print this widget, but obviously I do not want to print the background, I want to print with differing text colors or have the style of frames slightly modified. As I do not really want to iterate through all subwidgets with a special "print" function, which I would need to attach to all widgets (how to add "print" to a QLabel?), I would like to use paintEvent. If I have a hierarchy MyWidget - derived from - some QWidget, I would like to insert a sublayer MyWidget - MyPrintWidget - some QWidget, where myPrintWidget::paintEvent would check, if the current print is going to the screen (thus call QWidget::paintEvent), else if we are printing to the printer, call some function MyPrintWidget::drawWidget instead. Is this the right way to print-enable a widget? How can I figure out in paintEvent, that I'm printing to a printer instead of the screen? Is there a good example of printing complex widgets?

• [WPF] Drag and drop between 2 popups

  - by timhaughton

  Our application is a WPF (4.0) AppBar docked to the top of the desktop. Various buttons in the AppBar produce Popups containing various data (in ListBoxes). I am trying to implement drag and drop of items between 2 Popups. It's pretty standard boiler plate stuff using Josh Smith's draggable ListBox that I've used half a dozen times before. Drag is initiating correctly, but the target Popup is not receiving the DragOver or Drop. Is this a focus issue? Or is there something else at work here?

• Is gzip compression useful for mobile devices?

  - by Savageman

  Hi SO, I'm wondering if anyone has a clue on whether the gzip compression is as much useful on mobile devices than it is on a desktop computer. Will the phone use more battery? Or will it save some because of the bandwidth saving? Will the page page load faster or is the uncompress process slow on those limited devices? Does the compressed data actually reach the end-user or is it uncompressed somewhere by the 3G provider? (this may be a stupid question, sorry). Thank you.

• MVC design pattern - who loads view initially

  - by enableDeepak

  This query is about MVC design pattern in general and not ASP.net MVC framework I understand in MVC (desktop application): 1. User clicks something in view 2. this is passed on to controller to manage 3. controller makes some changes in Model 4. Model calls method on view which has the logic to refresh UI Questions around these: Q1) Can controller also modify View or Model only updates View? Q2) When screen loads for the first time, there is no Model change. Then, who fetches data from model and populates view? View directly calls Model and populates itself OR controller gets data and passes to view method OR some dummy event is raised at Model which updates View?

• Key logger wont record key strokes without console

  - by Daniel Gopar

  I created a small basic key logger in C++. For some reason when I compile and run the program with the console displayed, it will record every key stroke I make in whatever program I am using such as a browser and store it in a text file. However when I make it so that it WON'T display a console window, it will not record anything and it's just a process in the background doing nothing. Here is the link to my code: http://pastebin.com/4wqQyLJ9 The function that is giving me trouble with hiding the console, is the Stealth() function. Any suggestions, tips or hints will be helpful. Thanks.

• Define a class dynamically?

  - by Pekka

  Is there a way to dynamically and conditionally create a class definition in PHP, i.e. if (condition matches) include file containing class definition else class myclass extends ancestor_class { .................... } without eval()? My background is the accepted answer to this question. I am looking for the best way to build a untouchable core library, with user-defined empty classes extending the core library if necessary. I want to create the final class definition "on the fly" if there is no user-defined empty class for a certain ancestor class.

• Is both approach same ?

  - by Harikrishna

  I have one datatable which is not bindided and records are coming from the file by parsing it in the datatable dynamically every time. Now there is three columns in the datatable Marks1,Marks2 and FinalMarks. And their types is decimal. Now for making addition of columns Marks1 and Marks2 's records and store it into FinalMarks column,For that what I do is : datatableResult.Columns["FinalMarks"].Expression="Marks1+Marks2"; It's works properly. It can be done in other way also is foreach (DataRow r in datatableResult.Rows) { r["FinalMarks"]=Convert.ToDecimal(r["Marks1"])+Convert.ToDecimal(r["Marks2"]); } Now I don't know that which is the best way to do this means performance wise. Is first approach same as second approach in background means is both approach same or what?

• CSS issue with margin: auto

  - by user1702273

  Hi am having an issue with the margin auto of my website where i have a wrapper div with the width set to 1000px and the margins top and bottom to 0 and left and right to auto. I have a navigation menu in the side bar, where i used java script to replace the same div with different tables. when i click a link in the menu the wrapper shifts right some px and the comes to original, I don't want that action i want the wrapper to be static and not to vary at any time. how can i achieve that. when i set the margin to just 0, so problem with positioning. But i want the wrapper to be centered. Here is my css code: body { background-color:#E2E3E4; color:#333; margin:0; padding:0; font-size: 12px; } #wrapper { width:1000px; margin:0 auto; margin-bottom:10px; } #header1 { width:1000px; height:44px; margin:0 auto; background-color:#ED6B06; } #header2 { width:1000px; height:40px; margin:0 auto; border-bottom:1px solid #EDE9DE; } #header3 { width:1000px; height:40px; margin:0 auto; border-bottom:1px solid #EDE9DE; } #header2 p { margin:0 auto; font-size:20pt; color: #364395; font-smooth: auto; margin-left:15px; margin-top:5px; } #welcome { width:600px; float:left; padding:10px; margin:0 auto; } #status{ margin:0 auto; width:50px; float:right; padding:10px; margin-top:3px; margin-right:15px; } #content { width:780px; float:right; } #sidebar { width:150px; margin-top:15px; margin-left:10px; float:left; border-right:1px solid #EDE9DE; margin-bottom:25px; } #footer { clear:both; margin:0 auto; width:1000px; height:44px; border-top:1px solid #EDE9DE; } HTML: <html> <head> <link rel="stylesheet" type="text/css" href="style/style.css" media="screen" /> <title>Pearson Schools Management Portal</title> </head> <body id="home"> <div id="wrapper"> <?php include('includes/header1.php'); ?> <?php include('includes/header2.php'); ?> <?php include('includes/header3.php'); ?> <div id="content"> <h2>Welcome to Portal!</h2> </div> <!-- end #content --> <?php include('includes/sidebar.php'); ?> <?php include('includes/footer.php'); ?> </div> <!-- End #wrapper --> <link rel="stylesheet" type="text/css" media="screen" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/base/jquery-ui.css"> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript" src="http://jzaefferer.github.com/jquery-validation/jquery.validate.js"></script> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script> <?php include('scripts/index_data.js'); ?> </body>

• ModalPopupExtender doesn't work on IE6 frame layout

  - by Joe

  I'm using a "frame" layout similar to the one in this excellent answer: a div #top at the top of the page, a div#left on the left, and a div #main with the main content. The #top and #left divs contain navigation menus. Now I want to use a popup div using the AjaxControlToolkit ModalPopupExtender inside the content (#main) div. This works fine on IE8 (where #top, #left, #main all have position:fixed), but when I run it on IE6, the modal background only covers the #main div - I need it to cover the whole of the page including the #top and #left navigation divs. Looking at the script for ModalPopupExtender, it appears to be searching up the parent hierarchy until it finds a parent with position relative or absolute. And in the IE6 rendering, the #main div has position:absolute because position:fixed is not supported, which I guess explains what is happening. Any suggestions for the best/easiest way to get this working properly on IE6? Ideally without modifying the ModalPopupExtender code, but I'll do this if I have to and it's the best solution.

• Opening all external links in Phongap's ChildBrowser using jQuery Mobile

  - by Adam

  I'm using jQuery Mobile & Phonegap, and have the following code to open all external links in a certain div with the ChildBrowser: $('.someDIV a').live('click', function() { var thisUrl = $(this).attr('href'); PhoneGap.exec("ChildBrowserCommand.showWebPage", thisUrl); return false; }); For some reason, while the page loads in the childbrowser, it also loads in the background, as if there's no "return false". I've found a workaround by giving the link's href attribute a value of "#", and using the title for the url like this: And updating the jQuery code accordingly, but this is a problem where my links are dynamically generated, and I can't have the url in the title attribute. Any ideas how to solve this?

• Toastr.js notifications as modal notfication

  - by Maxsteel

  I know it's not what toastr (or toast notifs in general) are meant to be used for, but I want to use them as a modal notification. My idea is following. On toast show: toastr.options.onShown = function() { //Create an overlay on the entire page} Overlay: #overlay { background-color: rgba(0, 0, 0, 0.8); z-index: 999; position: absolute; left: 0; top: 0; width: 100%; height: 100%; display: none; } And on toast close: toastr.options.onHidden = function() { //make overlay go away } Also, I'm setting timeout of toast to 0 so it won't disappear by itself. Question: I want the toast notification to stay atop the overlay and not behind it as overlay will cover everything. How can I do it?

• Getting ready for learn html5

  - by vtortola

  Hi, I'm a desktop application developer, and I plan learning html5, but as it's not released, there is no (almost) published books and no too much infomation from beginners on the web... I fell I should start with html4 and the current web development skills. I think, I should start with html4, css and javascript... but there are so many technologies related that I get lost :D So, what current technologies will be sill used when html5 be released? I mean, what about "jquery" and "ajax"? I know they are javascript under the hood, but will they still make sense in the future? What would you recommend me considering that I have just a little bit of html knowlegde, almost null CSS and completely null in javascript? Thanks in advance.

• How is an SOA architecture really supposed to be implemented?

  - by smaye81

  My project is converting a legacy fat-client desktop application into the web. The database is not changing as a result. Consequently, we are being forced to call external web services to access data in our own database. Couple this with the fact that some parts of our application are allowed to access the database directly through DAOs (a practice that is much faster and easier). The functionality we're supposed to call web services for are what has been deemed necessary for downstream, dependent systems. Is this really how SOA is supposed to work? Admittedly, this is my first foray into the SOA world, but I have to think this is the complete wrong way to go about this.
