• C# and Linq: Generating SQL Backup/Restore From Code

  - by mdvaldosta

  I'm working with a C# and Linq to SQL Winforms app and needed to integrate backup and restores through the program. I used SMO and got it working pretty smoothly. The issue, however, is that the app is deployed using ClickOnce, which I like very much - but since I had to include the dll's the download size jumped from 3mb = 15mb. I know they've only got to download it once, but it also sucks for me as Visual Studio 2010 seems to upload the dll's every time and that takes a while on AT&T broadband (eh). So, anyone have any suggestion on how I can work out an effective backup/restore solution without using SMO objects?

• Alert on moving to a different page of a grid when user changes contents of textboxes in a Grid

  - by Ashish Gupta

  In a ASP.NET application I have a paging RadGrid which shows up textbox in each row. Outside the grid, there is an OK button to save the content of all the textbox. If user changes text in any one or more of the textbox and without clicking on the "OK" button, tries to move to a different page number (of the grid by clicking on the page number), he should be prompted for confirmation of save or cancel the changes. I am guessing that one can write a Javascript function which would look for any form input control (textbox in my case) and detect changes and If there are changes, would prompt the user. However, I am not sure where I can call this function from? Any suggestion on this or a better way to achieve this would be appreciated. I am using RadGrid but I guess this should be applicable to GridView as well.

• Searching Database by Arbitrary Date in PHP

  - by jverdi

  Suppose you have a messaging system built in PHP with a MySQL database backend, and you would like to support searching for messages using arbitrary date strings. The database includes a messages table, with a 'date_created' field represented as a datetime. Examples of the arbitrary date strings that would be accepted by the user should mirror those accepted by strtotime. For the following examples, searches performed on March 21, 2010: "January 26, 2009" would return all messages between 2009-01-26 00:00:00 and 2009-01-27 00:00:00 "March 8" would return all messages between 2010-03-08 00:00:00 and 2010-01-26 00:00:00 "Last week" would return all messages between 2010-03-14 00:00:00 and 2010-03-21 018:25:00 "2008" would return all messages between 2008-01-01 00:00:00 and 2008-12-31 00:00:00 I began working with date_parse, but the number of variables grew quickly. I wonder if I am re-inventing the wheel. Does anyone have a suggestion that would work either as a general solution or one that would capture most of the possible input strings?

• PHP photo gallery with multiple upload form

  - by NightMICU

  Hi everyone, I am trying to develop a PHP driven gallery with a form that has at least four file upload boxes, each with its own title and caption. I have been using php.upload.class to process uploaded photos but not sure how I would go about handling each individual upload while preserving its details (title, caption). Is there a practical way to do this or should I instead upload just the photos and then have the user add titles and captions on the next page? Any help/suggestion would be greatly appreciated. Thanks!

• Spring/Hibernate: InvocationTargetException when deleting entity

  - by niklassaers

  I'm sorry if this question is a bit vague, but I'm quite confused. I've got a controller that calls a service to delete an entity and then create an entity in its place. In the service, I've got my DAO, and my entity, and I want to delete my entity, so I call DAO.delete(entity); Then, seemingly out of nowhere, I get an InvocationTargetException. The parameters here are: method: public org.springframework.web.servlet.ModelAndView tld.myproject.view.web.controller.MyController.replaceEntity(org.springframework.web.multipart.MultipartFile,javax.servlet.http.HttpServletRequest) target: tld.myproject.view.web.controller.MyController@185918e args: [org.springframework.web.multipart.commons.CommonsMultipartFile@14812a6, org.springframework.web.multipart.support.DefaultMultipartHttpServletRequest@c08a64] ex: java.lang.reflect.InvocationTargetException private Object doInvokeMethod(Method method, Object target, Object[] args) throws Exception { ReflectionUtils.makeAccessible(method); try { return method.invoke(target, args); } catch (InvocationTargetException ex) { ReflectionUtils.rethrowException(ex.getTargetException()); } throw new IllegalStateException("Should never get here"); } Does anyone have a suggestion to what's going on? Anything I can use in my debugging? Cheers Nik

• How can I use an Ant foreach iteration with values from a file?

  - by Egon Willighagen

  In our Ant build environment, I have to do the same task for a number of items. The AntContrib foreach task is useful for that. However, the list is in a parameter, where I actually have the list in a file. How can I iterate over items in a file in an foreach-like way in Ant? Something like (pseudo-code): <foreach target="compile-module" listFromFile="$fileWithModules"/> I'm happy to write a custom Task, and welcome any suggestion on possible solutions.

• Suggestions for a mashup application

  - by Raffo

  I have to write a mashup application for an university course and I have to use some APIs, but I need to choose by myself what to use and what the final application should do. Unfortunately I never made an application like this, so I'm not sure what to do... I don't want to code a stupid app which uses google maps' APIs since the web seems to be full of stuff like this. Have you got any suggestion for me? Is there any mashup web app you want that's still not there?? I can use JAVA, GWT (and google app engine of course) or python, but I also accept suggestions for other languages. Thank you in advance!

• How to use C to write to flash drive bootsector despite error 'Failed to open file to write.:Permiss

  - by updateraj

  My goal is to manipulate the boot-sector in my flashdrive (volume E:) I am using XP. I am able to read the boot-sector FILE *fp_read = fopen("\\\\.\\E:", "rb"); /* Able to proceed to read boot sector */ however i am not able to open the file to write using fopen in 'wb' mode.

• Efficiency of while(true) ServerSocket Listen

  - by Submerged

  I am wondering if a typical while(true) ServerSocket listen loop takes an entire core to wait and accept a client connection (Even when implementing runnable and using Thread .start()) I am implementing a type of distributed computing cluster and each computer needs every core it has for computation. A Master node needs to communicate with these computers (invoking static methods that modify the algorithm's functioning). The reason I need to use sockets is due to the cross platform / cross language capabilities. In some cases, PHP will be invoking these java static methods. I used a java profiler (YourKit) and I can see my running ServerSocket listen thread and it never sleeps and it's always running. Is there a better approach to do what I want? Or, will the performance hit be negligible? Please, feel free to offer any suggestion if you can think of a better way (I've tried RMI, but it isn't supported cross-language. Thanks everyone

• With Eclipse, in a PHP project with SVN, how to "tell" Eclipse to find autocompletion choice only in

  - by ranskalainen

  Hello, Using Eclipse on a PHP Project, I recently created a tag on my SVN. Since that day, let's say I'm working on a class in my trunk, when I ctrl+space in my code, Eclipse is getting really really slow (sometimes even freeze), and if I'm lucky, it will give me 2 responses for autocompletion : One referencing some method/class from the tag, one referencing method/class from the trunk. But right now, only the reference from the trunk would be useful for me. Is there a way to limit where Eclipse parse the code to give back autocompletion suggestion ? Thank you

• Presenting UIModalViews in Landscap mode

  - by Dominik

  Hello, I'm trying to present some UIModalFormSheets in a my iPad application. It's working without any problems, except one thing: When I have my iPad in landscape mode my modal form sheet is moving to the center of the screen and THEN rotates into the appropiate angle. All I want is to present the modal form sheet in the right angle according to the view mode (portrait or landscape), BEFORE it is displayed, so that the user doesn't see this rotation. I have tried all the modes for modalTransitionStyle and modalPresentationStyle, but nothing seems to prevent the modal form sheet from rotating after it is displayed. This is what I'm doing: NewFavouriteSheet *newFavouriteSheet = [[NewFavouriteSheet alloc] initWithNibName:@"NewFavouriteSheet" bundle:nil]; newFavouriteSheet.modalPresentationStyle = UIModalPresentationFormSheet; [self presentModalViewController:newFavouriteSheet animated:NO]; Does anyone has a suggestion on how to show the modal view in a correct way? Thanks for help. Dominik

• How to use Event notification in Solaris 10 when a directory change

  - by user357594

  I read the following page: Robert Benson's article on ECF developers.sun.com/solaris/articles/event_completion.html I also read the Solaris man pages but they are not very clear of how to use event notifications for directories. For example, If I add a new file into a directory, I would like to get some notification of that event. I found this link: blogs.sun.com/praks/entry/file_events_notification Which has what I need but it is for Solaris 11 ( which is not in the market yet). Based on the link below, I don't want to use poll because I want to get the performance advantage of events. blogs.sun.com/dap/entry/event_ports_and_performance Any suggestion is highly appreciated! -Armando.

• Resharper Autocomplete Issue

  - by Gene

  Hi All, I've been using resharper with the resharper automplete off (just find VS better for my purposes currently), but despite trying every setting I've tried, whenever I use a resharper template (such as tab-completing an if - if block), the resharper autocomplete dialog comes up in addition to the visual studio dialog (thus if they don't autocomplete to the same thing, or I accidentally hit enter, whatever I originally typed is replaced with the wrong resharper suggestion, effectively highlighting why I turned it off in the first place). A. Has anyone every seen this before? (I ask since I might have turned on/off a number of settings in a strange/incompatible way and perhaps a clean install might clear it up.) B. Any suggestions? :) (Visual Studio 08 SP1, Resharper 4.5.2 - only other tools installed are DevExpress, but they have long since been disabled) Thanks all!
