• Is there a way to bring an application's GUI to the current desktop?

  - by Davy8

  Background: Started a fair amount of work before realizing that a Windows Service cannot start an app with a GUI that displays without potential problems. The proper solution of separating the GUI of the app to be started is non-trivial, so I'm trying to think of alternative solutions. There is a GUI to manage the service that is a separate executable, but the process to be launched (actually multiple instances of it) has its own GUI that needs to be shown. It doesn't need to be made visible by the service itself, but it needs to be at least able to be made visible by another process with a visible GUI. The Windows User that is running the service and that needs to see the GUI of the launched process is the same and known at install time. Is there some way to accomplish this or is it back to the drawing board? Also both the service and the app to launch are both our code and modifiable.

• Problem with running a program from flashdrive

  - by rajivpradeep

  I have a USB drive with two partitions in it, one hidden and one normal. I have an application which swaps the memory and runs the flash application in hidden zone. The problem is that the application works fine on Windows 7 and when run on Win XP, it swaps the partitions but doesn't run the flash applications but just keeps running in the background. I can see it in task manager. But, when I copy the application to desktop and run, it runs with no glitch. I was facing the same problem on Win 7 too, but it was running as required when I ran it using "Run in XP mode" and then I applied a SHIM and is running since then as required. The application is built using VC++ 2008. does anyone know the solution?

• Is Amazon SQS the right choice here? Rails performance issue.

  - by ole_berlin

  I'm close to releasing a rails app with the common networking features (messaging, wall, etc.). I want to use some kind of background processing (most likely Bj) for off-loading tasks from the request/response cycle. This would happen when users invite friends via email to join and for email notifications. I'm not sure if I should just drop these invites and notifications in my Database, using a model and then just process it with a worker process every x minutes or if I should go for Amazon SQS, storing the messages and invites there and let my worker retrieve it from Amazon SQS for processing (sending the invites / notifications). The Amazon approach would get load off my Database but I guess it is slower to retrieve messages from there. What do you think?

• Gallery has too much padding in IE7

  - by Amber

  My Flickr gallery looks good in all browsers except IE 7. What else do I need to put in my CSS code for it to not look so lopsided in IE 7. I added the display: block but it didn't do anything. a img { display: block; *display: inline-block; float: left; border: none; padding: 3px; background-color: #fff; border: 1px solid green; margin-right: 15px; margin-bottom: 15px; } Right now it looks like this. Is there something I'm doing wrong with the CSS? Should I be adding in something for IE so it can read it properly? This is my site

• Using checkbox to enable eventlistener

  - by Lefty

  I have looked for a solution to this for days and days. The examples I found don't make sence to me, probably because I am both old and new (old to life and new to android/jave). I would like to add a checkbox to my preference activity that would either enable or disable receivers. This is for a service which will run in the background, at boot completed, and will depend on two things 1)is the preference true and 2) is wifi enabled. So it would work something like this; user turns on phone boot completed checks if receivers are enabled (set by checkboxpreference) if checkboxpreference is true - looks for wifi if wifi is true - registers receivers Also required would be if wifi or checkboxpreference goes "false", unregister receivers. Thanks

• Styling the selection color of an input type=text, possible?

  - by Tommy

  Having an input <input type="text" id="myTest" value="bla bla bla"/> and doing this (using jQuery) $('#myTest').select(); causes "bla bla bla" to be selected with default dark blue selection color. Now, is there any way I can change this color using css? css3 can change selection using for instance ::-moz-selection { background: #ffb7b7; } but this only works on text in other elements, not in html inputs. Any ideas? /T

• 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.

• Aggregate Functions in Index with IBMDB2

  - by Erkan

  Is there any way to pre aggregate results of aggregate functionts (f.i. count()) and store it in an index? The background is: i want to speed up count() queries. So that: Select count(users) from TE123 where region = 'A'; would be supported by an index like Region Count(Users) A 548 E 458 I know that MQTs would also help for this problem. However, in this case it is not possible to use MQT, as we use kind of an ORM and we don't want to define Entities on MQTs. I just slightly remember - one DBA told me - that there is such a function planned for DB2 V10.

• C# - Thread does not abort on application closing

  - by michal

  Hi, I have an application which does some background task (network listening & reading) in separate Thread. It seems however that the Thread is not being Terminated/Aborted when I close the application (click "x" button on titlebar ;)). Is that because the main Thread routine is while(true) {...} ? What is the solution here? I was looking for some "interruption" flag for the Thread as the condition for "while" loop, but didn't found any ...

• Is a new thread in a Visual Studio test project aborted when the test ends?

  - by Michel

  Hi, i have to do some message exchange with a 3rd party (in a website). When the client posts a page, i start the message exchange. When that doesn't succeed for some reason, i report this to the client by rendering the page with a message. On the background, in a separate thread, i start a process to send abort messages to the 3rd party. I can't do this while the user is waiting for the page to come back, because it might take a few minutes. But in a test project, the test ends when the message to the 3rd party is sent, and after the new thread is started. But it seems that the new thread also ends, when the test is done. Is that normal behaviour? I do start the thread in a new class with a reference to 2 objects from the class which tries to send the message in the first place, may that be a problem?

• How to style a standard GWT component (TabBar) differently?

  - by Mike Petterson

  I am using a TabBar and I want to style the component in different ways. So one time this style, another time that style. I thought this will work but it didn't: TabBar t = new TabBar(); t.addTab( "1" ); t.addTab( "2" ); t.addStyleName( MyResources.INSTANCE.css().slickTab() ); And: public interface MyCssResource extends CssResource { String slickTab(); } In the CSS .slickTab .gwt-TabBar .gwt-TabBarItem { background-color: #ff0000; font-weight: normal; } But the appearance don't change.

• Where should I store my App specific config files in WPF

  - by Akash Deshpande

  Background : I have some Application Data. i.e. the Database, come important config files. This data is vital for the application to start else it is exited. Problem : Where should I store this data. i.e in which folder and where. Right Now (This is wrong) it is stored in a folder in Debug/App_Data. But is causing issues in git and when we publish the App the data is not found. So where can we store this folder ? Present Structure is "WpfApplication2\WpfApplication2\bin\Debug" These Files need to be present when the app is started. So they need to be a part of the app itself.

• css override not working?

  - by Karin

  I have three tabs that change styles when clicked. class="active" gives the tab the same background as the tab content, while class="inactive" has another color. My problem is the text on the tabs, something's weird with the CSS. The default state of class="active" looks as it should, while the inactive tabs are underlined even though my CSS says text-decoration: none !important; and the clicked active tab text becomes extra bold (or maybe it's a shadow). Please look at my fiddle: http://jsfiddle.net/m8wQM/170/

• 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?

Is there any way to reduce these efforts? I had tried with "class="@string/class_name" but its not working.

• Creating a contact form using divs with 4 extra divs for "Corners"?

  - by mark smith

  Hi there, i have tried to create a contact form (a standard form, square in nature but with rounded corners)... I can't use the CSS3 specs so i have an image for each corner.. I have set the images on the background-image and no repeat but it seems if the div is empty then it doesn't display, is there a hack - although prefer an alternative clean method :-) So on the top level i presume i have 1 div for the Upper-Left (corner) and then the upper-middle (just has a color assigned) and then a div for the upper-right (corner) .. so i presume i need to float all these to the left??? Or am i missing something? Thanks in advance

• how does serializable work in java?

  - by Karl Trumstedt

  If I have an instance of a class that I store in a session I need to make it serializable. This class has a static variable, will this be serialized in every instance stored? The static variable is a reference to a cache containing a lot of data in the background. Will all of this data be serialized? If so, it seems preferable to make this variable transient and re-fetch the cache instance each time the instance is restored. Maybe not store the cache instance at all in the class. Will the constructor execute when a class is restored from a serialized state? if not is there any other method I can use to re-instate a transient variable?

• 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?

• What is the most mature library to render equirectangular images in Flash?

  - by Dave Viner

  I have a series of equirectangular images. I'd like to display them in a custom Flash player so that the user could see the spherical nature of the images, and "look up", "look down", "look left/right" (or pan, zoom, etc). (Note that I have a long series of images, so the library must allow for dynamic loading of the images themselves, rather than having the images "baked" into the SWF player.) What is the best library to manage the display of the equirectangular images in Flash? By "best", I mean the most mature, most reliable, most robust, and fastest performing. For reference, an example of an equirectangular image can be found at http://archive.bigben.id.au/tutorials/360/background/projections.html.

• UITextField placeholder looks strange when UITableViewCellSelectionStyleGray

  - by mongeta

  Hello, I've set the background color of my UITableViewCells to Gray. But if there's a UITextField in the cell, the placeholder doesn't change their color to white/black and it's almost impossible to read it, and look stranges. The UILabel from the cell changes their color when it's selected or not, but the placeholder remains always the same. There's a simple solution ? I don't want to add some UILabel and use it as a placeholder, etc. etc. Thanks, r.

• 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 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!
