• Can an appdomain in C# be restricted to one directory?

  - by Caerbanog

  I am developing a plugin host. The plugins should have as little trust as they need, however I want to have the possibility for a plugin to read and write files. Can the AppDomain where the assembly will be loaded be restricted to have access to only one directory for reading and writing? Other options and ways to go about this are also appreciated like for example easy ways to stream file data from the host to the plugin (reading) and from the plugin to the host (writing). If its relevant: I am using the MAF infrastructure for the plugins. http://msdn.microsoft.com/en-us/library/bb384200.aspx

• How do I search nodes of XML document for text? Or convert to SQL tables?

  - by netefficacy

  Hi I have an XML file and would like to run a search on the nodes for text that matches user input. My options are: Convert the XML file to a SQL table and run the search against the table records. Search the XML nodes themselves. The problem is that I cannot find a open source conversion utility, nor can I figure out how to search the XML nodes. I can use PHP, Ruby, or Python for the search code. Any pointers on how can I do 1 or 2? Thanks

• several jquery ui theme switcher problems (cookie, different themes for different pages, etc.)

  - by powerboy

  I just try putting the jquery-ui theme switcher on my website. Seems that there are some problems: Cookie does not work. When I close the browser and reopen the webpage, the default theme will load instead of the one selected before. The selected theme is valid for current page only. If jumping to another page, it will load the default. I want to select once and apply to all pages. There is a flash of the default theme before the selected theme get loaded. Anyone know an easy way deal with these problems? I know I can implement my own cookie solution based on that theme switcher, but I was so surprised that the author did not provide options to do these.

• Magento module - database not initialized?

  - by Magnus

  Hello, So I've installed an extension in my Magento Enterprise. I've been able to configure new options in the admin interface after installing the module. However in the frontend it complains "table not found". Checking the database that is indeed true. Seems the mysql4-*.php scripts have not been run or failed. Is there a log or something I can look at to see what goes wrong? From what I've read (difficult to find documentation on this) the modules db should've been initialized on the first request after it was installed and activated. Any other suggestions to what I can check to find out why it's not initialized properly?

• Attach to Property's setter

  - by StupidDeveloper

  I haven't found similiar post so I'm asking this. Let's say I defined somewhere an application wide available static Property (I mean it's not local) and in one class I would like to know when this property is being changed. Apart from aop (transparentproxy etc.) which I think doesn't suit me well here (and I can't add that to project anyway), what are the options here? One solution I can think of, which is probably a very nasty one, is to use some event that would be executed in the setter and just attach it in the class(es) which needs that. Something like: public static event EventHandler CurrentNumberChanged= delegate {}; public static int CurrentNumber { get { return currentNumber; } set { currentNumber = value; CurrentNumberChanged(null, EventArgs.Empty); } } I know it's really unsafe to use such events ( read here ). And since I would use it in asp.net makes it even more ugly. Do you have any advices ?

• What is the accepted way to replace java.util.Date(year,month,day)

  - by dagw

  I'm trying to do something really simple, but starting to realize that dates in Java are a bit of minefield. All I want is to get passed groups of three ints ( a year, a month and a date) create some Date objects, do some simple test on them (along the lines of as date A before date B and after January 1 1990), convert them to java.sql.Date objects and pass them off to the database via JDBC. All very simple and works fine using the java.util.Date(int year,int month,int day) constructor. Of course that constructor is depreciated, and I'd like to avoid using depreciated calls in new code I'm writing. However all the other options to solve this simple problem seem stupidly complicated. Is there really no simple way to do what I want without using depreciated constructors? I know the standard answer to all Java date related questions is "use joda time", but I really don't want to start pulling in third party libraries for such a seemingly trivial problem.

• Most efficient way to maintain a 'set' in SQL Server?

  - by SEVEN YEAR LIBERAL ARTS DEGREE

  I have ~2 million rows or so of data, each row with an artificial PK, and two Id fields (so: PK, ID1, ID2). I have a unique constraint (and index) on ID1+ID2. I get two sorts of updates, both with a distinct ID1 per update. 100-1000 rows of all-new data (ID1 is new) 100-1000 rows of largely, but not necessarily completely overlapping data (ID1 already exists, maybe new ID1+ID2 pairs) What's the most efficient way to maintain this 'set'? Here are the options as I see them: Delete all the rows with ID1, insert all the new rows (yikes) Query all the existing rows from the set of new data ID1+ID2, only insert the new rows Insert all the new rows, ignore inserts that trigger unique constraint violations Any thoughts?

• My choice of fieldname for CakePHP's form helper is not working properly, why?

  - by grokker

  Hi, I'm creating an AJAX form. The problem is when I'm trying to create a input form with formhelper, my input's name attribute is not correctly renedered in the view. Here's my code: $form->input('MainAttribute.'.$i.'.SubAttribute.'.$j.'.score', array('label' => '', 'options' => $scores)); I created it that way because I want SubAttribute to be inside MainAttribute. When I inspect the HTML, the name attribute of the form is cutted of like: name="data[SuperMainAttribute]" How can I specify the name attribute to the one that I'm planning on doing? (e.g. data[MainAttribute][0][SubAttribute][0][score])

• Tool to view/plan keyboard shortcuts?

  - by Willfulwizard

  I'm curious if there are any tools available* that will help me map out keyboard shortcuts for the application I'm working on? Being able to see what combinations are in use, the relationships between normal, ctrl, shift, and alt combinations, and especially what combinations are NOT in use, would be wonderfully helpful. Please forgive me if I am missing an obvious solution, but I've had no luck searching for such a tool myself, due to every application in existence having its own keyboard shortcuts, and all of those being listed on the web. Thanks! *Naturally, I'd prefer free/cheap, but it can't hurt to hear about any expensive options.

• Crystal Report | Printing | Default Printer

  - by Akshay J

  I am making one application where user will print invoices which I am displaying using Crystal Report. The user showed me his current application made using ForPro. In that application, under Printer Options form, one can see all the printers currently installed and the user could select default printer. When the invoice is made, the user presses the print button, then there is one dialog asking for no. of copies. When it's entered, the invoice gets printed directly, without any Print Dialog Box. If the user wants to change the printer again he/she will change it in the Printer Option form. I want to know if similar thing is possible in Crystal Report and need guidance on how to approach for it.

• Enter a letter when prompted by another command

  - by kij

  Hi all, I'm trying to automate the installation and deployement of an application. To do it, i have a shell script with the following instructions: /usr/local/bin/amf install -u $1 -p $2 $localTarget where $1, $2 and $localTarget are options for the command named 'amf'. The problem is that the 'amf' command make severall instructions and ask the user to enter a letter during those instructions (to confirm the installation). At the moment, i can't bypass or modify the behaviour of the 'amf' command, so my question is: How can i catch this behaviour and/or automatically enter a letter in my script. This behaviour currently make my script not working, because the 'amf instal...' instruction is followed by another command to start my application. But as the install failed, the application can't start. Thanks in advance for your help. Best regards. Kij.

• Git: Make one branch exactly like another

  - by G. Martin

  I am relatively new to Git, and I'm still not very comfortable with it. Right now, I'm looking for the command/options/magic that can make the current branch look like another branch; that is, to merge them, but when a conflict arises, to always choose the difference in the branch that is being merged into the current one. My situation is thus; I have an stable(ish) application on the "master" branch. I also have another branch, called "feature". I basically want to make changes/additions/deletions to feature until I like the new feature I'm working on. Once I feel it is ready, I want to make the master branch look identical to the feature branch. I know this probably isn't a best practice, but as I said, I'm new to Git. I plan on learning how to do more complicated things in the future, but for now, this is all I need. Thanks, SO!

• Display the y value of a uiImageView during an animation

  - by user1422132

  I have the following code: NSString *yValue; yValue=[[NSString alloc] initWithFormat:@"%1.2f" , imageView.center.y]; CGRect labelFrame = CGRectMake( 10, 100, 200, 50 ); UILabel* label5 = [[UILabel alloc] initWithFrame: labelFrame]; [label5 setBackgroundColor:[UIColor blackColor]]; [label5 setText: yValue]; [label5 setTextColor: [UIColor orangeColor]]; [self.view addSubview: label5]; This correctly shows the y value of the UIimageView but the problem is that it only shows the ending y value. When a person flicks the UIImageView I animate it using: [UIView animateWithDuration:2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{ recognizer.view.center = finalPoint; } What I want is the label5 to display the y value of the imageView during the animation not just after. Is it possible to do this?

• Sharing Code, Images and Core Data models across iPhone and Mac project

  - by Robert

  Hi, I am maintaining a fairly large mac project and an iphone client for this project. Some code as well as some images and core data models are shared between these two projects. I want to create a shared framework containing this shared components but to my surprise, frameworks like we cocoa developers known them are not supported on the iphone os. Currently I see the following options: a) Include the files in both projects (much tedious work) b) Create a static library for both projects and manually copying the images/core data models c) Create a static lib for iphone and a framework for mac Any suggestions?

• How can I search for the dot character using the search command?

  - by lk

  I'm trying to use the Search command in Vim: :Rs/F/T/X R = range F = text to find T = text to replace with X = options But, when I want to search for the "." (dot character) I'm getting some problems. The task: Replace all occurences of " ." (space dot) for "" (greater-than) So, first I tried this: :%s/ ./>/g But this changed me all the " ." (space ANY-CHARACTER) to the "" character. Then I remembered that the dot character is a special one, so I tried this: :%s/ \./>/g But vim threw me an error: E486 Can't find pattern " \." And finally I tried this crazy thing: :%s/" ."/>/g and this :%s/" \."/>/g But I got the same result: E486 Can't find pattern... So, how can I search for the dot character using the search command? PS: Sorry for my poor Enlish.

• Open URL with Safari no matter what system browser is set to

  - by Mark

  In my objective-c program, I need to open a URL in Safari no matter what the system's default browser is. That means that this won't work, because it could launch Firefox or whatever other browser: NSWorkspace * ws = [NSWorkspace sharedWorkspace]; [ws openURL: url]; I think I'm close with this: [ws launchAppWithBundleIdentifier: @"com.apple.Safari" options: NSWorkspaceLaunchWithoutActivation additionalEventParamDescriptor: NULL launchIdentifier: nil]; only need to figure out how to pass in the URL as parameter... Is there an easier way? Thanks!

• [C#] Creating standalone, console (shell) for domain-specific operations

  - by mr.b

  Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

• Animation with CGPoint in for loop

  - by user1066524

  I'm trying to do an animation where when a person clicks from point A to Point B on screen the object should slowly slide straight across (horizontally) from point A to Point B. I tried doing a for loop with something like: for (CGFloat i=previousPoint.x; i <= newPoint.x; i++){ [UIView animateWithDuration:10 delay:0 options:nil animations:^ { [magnifier removeFromSuperview]; magnifier = [[MagnifierView alloc] init]; CGPoint np = {i, newPoint.y}; magnifier.viewToMagnify = imageView; magnifier.touchPoint = np; [imageView addSubview:magnifier]; [magnifier setNeedsDisplay]; } completion:^(BOOL finished) { }]; } but for some reason it is moving it way up and then eventually to point B. sort of in a weird curve. how can I do this correctly?

• Content cacheing with PHP and CodeIgniter

  - by Josh K

  I have a couple of things I'm working on, namely a page that issues five or six cURL requests and processing content on them. I'm working with CodeIgniter on a LAMP stack but am open to other options. Naturally I would prefer to not rewrite the application. I would like to know if there are any ready-made / easily learned caching methods. Primarily I'd like to check if the page has changed since I last scrapped it. If it has, redownload and present. If it hasn't, serve up a cached copy.
