• Write-access for c# app in it's own exe dir in Windows 7

  - by fritz

  I know that user accounts in Windows 7 are limited by default, so a program cannot just write anywhere on the system (as it was possible in Win XP). But I thought that it would be possible that e.g. a c# app is allowed to write inside it's own exe-directory or it's subfolders at least (not everything is 'user settings' or should be written to "MyDocuments"...). So currently my c# app throws an UnauthorizedAccessException when trying to write inside the exe dir. Is there anything you can do in c# code to allow writing inside the exe dir?

  - by Barun

  Hi all, I am having a tough time trying to find a solution to the following design related to h:dataTable. I have certain number of rows predisplayed. The first column is only checkboxes.

• Java applet icon doesn't show

  - by user295744

  I have a java applet where I've changed the image icon that appears in the top left corner of the window. The code I use is this: Toolkit kit = Toolkit.getDefaultToolkit(); Image frameIcon = kit.getImage("src/myapp/resources/logo.png"); getFrame().setIconImage(frameIcon); Everything works fine until I deploy the applet to a standalone jar. In this case the icon that shows is the default icon, as if the code couldn't find the image. But the image is inside, although it is in the folder: myapp/resources/ What am I doing wrong here? Is this some weird java bug?

• 2 or more Controls only 1 is considered Active

  - by Don

  I have 2 controls (MyCtrl) next to each other called ctrlLeft and ctrlRight. Whenever one receives interaction it is considered active (by default the left one). I override OnDraw and customize the look of the active one a bit. Currently I have a property Active and an event that I subscribe to from all MyCtrl in there I store a reference to the active one like this: if (sender is MyCtrl) { ctrlActive = (sender as MyCtrl); ctrlLeft.Active = !(ctrlRight.Active = (ctrlActive == ctrlRight)); } Either way I need to have ctrlActive as I use it for other things but what I am wondering is if this is the best way make them aware of each other? Another option I thought of was to store references to every possible MyCtrl and then loop through em all and activate / deactivate the one that match sender just in case I in the future add a ctrlMiddle. Are my thoughts wrong, is there better options to do this. For example, how does radiobuttons accomplish their similar functionality?

• Crop & Resize Images in Wordpress

  - by Thomas

  I have gone through several plugins and I can't find a plugin that simply resizes and crops images to a specific size when they get uploaded. This is different from simply resizing one side of the image, I need it to resize the smallest side and then crop the largest side so that the image fits in a specific space. WP already does this by default with thumbnails but I need to do this with full-sized images as well. I was going to use: http://wordpress.org/extend/plugins/scissors/ but it doesn't work with my installation. Can anyone think of another plugin that does this? Is there a simple way to enable this behavior for full size images by modifying wordpress?

• Simplest way to extend doctrine for MVC Models

  - by RobertPitt

  Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?

  - by bluedaniel

  Ive got a page in Zend all set up that will for now just echo "Hello", this address is at http://dev.local/hello and works when visiting in the browser. However when I try to use curl or file_get_contents from a script in my zend 'public' folder I get a 500 Internal error message.

• How to handle Foreign key for optional field in .NET

  - by brz dot net

  What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution? Is there any other optimized solution for this? Thanks

• Implement Combobox/Option Menu funcionality on an iPhone interface?

  - by MikeN

  I want to give a list of choices on an iPhone GUI that works like a Combobox/Option menu. It needs to display the current selection, but on tapping it you should be able to change the current selection which will trigger a refresh of the screen. The option menu is letting the user choose which category a search is being performed under. So there is a default category and there are about 6 other choices. Idea 1: Use a label or button and when clicked on a new screen overlays that has all 6 options in a tableview, clicking on one closes the overlay screen and goes back to the main page with the updated value displayed. Idea 2: Should I use a totally different but native iPhone GUI widget like a Navbar at the bottom of the screen to reflect the different options?

• Sinatra Set Settings (Ruby)

  - by JP

  Using Sinatra in Ruby you can set the server's settings by doing: set :myvariable, "MyValue" and then access it anywhere in templates etc with settings.myvariable. In my script I need to be able to re-set these variables falling back to a bunch of defaults. I figured the easiest way to do this would be to have a function that performs all the sets calling it at the start of the Sinatra server and when I need to make the alterations: class MyApp < Sinatra::Application helpers do def set_settings s = settings_from_yaml() set :myvariable, s['MyVariable'] || "default" end end # Here I would expect to be able to do: set_settings() # But the function isn't found! get '/my_path' do if things_go_right set_settings end end # Etc end As explained in the code above, the set_settings function isn't found, am I going about this the wrong way?

  - by dev ray

  I have written the following code after creating the CRichEditCtrl // 06112010 : The following code was added to highlight the textselection in black color instead of the default blue color of CRichEditCtrl. - 1311 { m_EditControl.SetSel(0,100); CHARFORMAT2 cf1; cf1.cbSize = sizeof(CHARFORMAT2); m_EditControl.GetSelectionCharFormat(cf1); cf1.dwMask = CFM_BACKCOLOR ; cf1.dwEffects &= ~CFE_AUTOBACKCOLOR; cf1.crBackColor = RGB(0,0,0); m_EditControl.SetSelectionCharFormat(cf1); m_EditControl.Invalidate(); } After this I am adding text, but the selection still comes in blue color instead of Black. Could someone please tell me what I am doing wrong?? Thanks, DeV

• MySQL: check whether two fields on a model are always the same?

  - by AP257

  Sorry if this is a duplicate question, I'm a total database newbie and I'm probably using the wrong terminology to search for answers. I have a MySQL table as follows: +------------+---------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +------------+---------------+------+-----+---------+-------+ | placeid | int(11) | NO | PRI | NULL | | | grid | varchar(120) | YES | | NULL | | | vill | varchar(300) | YES | | NULL | | +------------+---------------+------+-----+---------+-------+ I'd like to find out whether 'grid' and 'vill' always occur in the same combinations or not. Maybe it'd be clearer with an example: placeid, grid, vill 1, TM1, Suffolk 2, TM1, Suffolk 3, WA8, Newcastle 4, WA8, Newcastle 5, WA8, York I'd like to construct a query that returns 'WA8' but not 'TM1', because 'WA8' occurs in combination with more than one vill. I would be SO grateful for any help!

• MVC Custom Model Binder Binding Multiple Values

  - by BMD86

  Hello everyone, I have a scenario in which I have multiple sources to bind to my model. For one, I have a view tied to a strongly-typed model, but this scenario also entails posting data to this view from a 3rd party site. Essentially, what I believe I am after in the custom model binding is to investigate the form values in the Request object within HTTPContext to see if I have a field such as "postedFirstName". If so, I want to bind that value instead of the textbox "FirstName" in my view. I've done a good bit of searching but have not find anything that exactly addresses such a scenario. This link was close, I thought, but not quite: http://stackoverflow.com/questions/970335/asp-net-mvc-mixing-custom-and-default-model-binding Any input is greatly appreciated!

• re-open background application via notification item

  - by user356764

  I got an app with tabs and a notification bar entry, when I send it to background (click on home button) and try to re-open the application via click on the notification bar, the app restarts (last selected tab is lost). When I hold the home button if the application is in the background and select it from there or click the app's icon on the homescreen, the previous state is restored per default (the correct tab is selected) IMO the intent of the notification is wrong, but I'm not sure how to fix it. In short: How to get a background application back to foreground when I click the notification entry? thx!

• sfConfig::get is not returning constants defined in app.yml

  - by morpheous

  I have an interesting problem. I am using Symfony 1.3.2. I have defined some constants in project/apps/frontend/config/app.yml and project/config/app.yml When I use the constant (correct spelling) in a piece of code like this $test=sfConfig::get('app_foobar'); the variable $test is assigned a null value. This is what I have checked so far: CHECK: cache files generated? (YES) CHECK: Do the cache files (config_app.yml.php) in the cache directory contain the constants defined in the app.yml file (YES) CHECK: Constant names used in the code matches the array keys found in config_app.yml? (YES) At this stage, I have run out of ideas. I dont want to supply a default value as a hack, because when I need to change the value of the constant, I will have to replace this in potentially hundreds of instances (too error prone). Is there anything that I have missed?. What could be causing this?

• Warn user of .NET Framework requirements

  - by moogs

  So I have an app (tool) that uses .NET 3.0. When run on a machine that only has .NET 2.0 (like the default Server 2008 R2 install) it crashes miserably. What I've seen so far is that people are using a shunt that will first check the .NET version. Is there a way to build it or add some manifest somehow so that the user is warned of this problem (and hopefully be prompted to install .NET)? I know this can be solved by an installer, but I have requirements that need it to be a standalone executable.

• What is the time taken by java to call a method in another package?

  - by satish

  I have an assignment where i need to do feasibility study on two of my approaches and find optimized one. There are two packages A and B User input is gathered in A and then sent to B for execution. Now my approaches are 1. Call B methods from package A one by one. 2. Create a common method in B and send all the input as parameters. Which is feasible and best one, I know 2 is good in terms of code optimization and less number of calls. But, I want to understand what will be the execution time difference in above approaches How much time does java take to call method in another package? Is there any default value like x nano seconds or y milli seconds. Based on the time taken I can choose the appropiate one. Thanks

• IPSec help on Windows 2003 please!!

  - by roacha

  Hey guys, I am trying to configure IPSec between a web and app server in our environment. I want all traffic between these two servers to use IPsec and be encrypted. These servers are on the same domain so i am currently using Kerebos for security, I have also tried pre-defined keys and nothing changed. When I try and ping between the servers I get "Negotiating IP Security" everytime. I have also confirmed that when I change "Require Security" to "Permit" everything works so IPSec is working, I believe its something with my security setup. Under the security tab both servers have the default 3DES keys first and then DES keys. I have also specified tunnel endpoints (the alternate server's IP). What am I missing? Thanks for any help..

• How do I simplify these NUNit tests?

  - by Lucas Meijer

  These three tests are identical, except that they use a different static function to create a StartInfo instance. I have this pattern coming up all trough my testcode, and would love to be be able to simplify this using [TestCase], or any other way that reduces boilerplate code. To the best of my knowledge I'm not allowed to use a delegate as a [TestCase] argument, and I'm hoping people here have creative ideas on how to make the code below more terse. [Test] public void ResponseHeadersWorkinPlatform1() { DoResponseHeadersWorkTest(Platform1StartInfo.CreateOneRunning); } [Test] public void ResponseHeadersWorkinPlatform2() { DoResponseHeadersWorkTest(Platform2StartInfo.CreateOneRunning); } [Test] public void ResponseHeadersWorkinPlatform3() { DoResponseHeadersWorkTest(Platform3StartInfo.CreateOneRunning); } void DoResponseHeadersWorkTest(Func<ScriptResource,StartInfo> startInfoCreator) { ScriptResource sr = ScriptResource.Default; var process = startInfoCreator(sr).Start(); //assert some things here }

• Constrain a table to have only one row

  - by finnw

  What's the cleanest way to constrain a SQL table to allow it to have no more than one row? This related question discusses why such a table might exist, but not how the constraint should be implemented. So far I have only found hacks involving a unique key column that is constrained to have a specific value, e.g. ALWAYS_0 TINYINT NOT NULL PRIMARY KEY DEFAULT (0) CONSTRAINT CHECK_ALWAYS_0 CHECK (ALWAYS_0 = 0). I am guessing there is probably a cleaner way to do it. The ideal solution would be portable SQL, but a solution specific to MS SQL Server or postgres would also be useful

• Android: Custom Clock widget Service work-around?

  - by Anthony Forloney

  I was interested in developing a clock widget for the homescreen and upon reading Home Screen Widgets tutorial, is there a pre-existing Service I could reference for updating the current time rather than re-inventing the wheel? I have currently Retro Clock on my android phone and noticed that when I click it, it pops up the Alarm Clock settings, but with the default Google Analog Clock widget, upon click does nothing. Is that because the Retro Clock widget implements the Alarm Clock service? If so, how can I go about referencing that service? Or do I have this all wrong and misunderstood? Any help is appreciated. EDIT: I believe implementing the service to update the clock would drain the battery life tremendously, any ideas on a work around or help shed some light on any performance issues with using Service?

• Visual Studio 2010 element names for theming

  - by Anthony Potts

  I am trying to figure out what the element name for the tooltip is in Visual studio so that I can change the style using the extension found here. Anyone know what that is? I am using the default theme which seems to have a white to light grey gradient on it. This is less than optimal since the text for the functions are also white. In a more general question (and perhaps better), is there anything that maps the names as they are found in the theme to where they are in the IDE.
