  • Changing the working directory for a process remotely

    - by Michael
    I've got an application that has a bug right now, but we're unable to update the end-user to get the fix out. What a possible workaround would be is to change the working directory to the application's install directory, but from what I can tell, there's no way to do that outside of the program itself. Is there some sort of Windows API call that can change other processes' working directories, or is that not available due to security issues? I figure it's not possible.

  • Advantage of creating a generic repository vs. specific repository for each object?

    - by LuckyLindy
    We are developing an ASP.NET MVC application, and are now building the repository/service classes. I'm wondering if there are any major advantages to creating a generic IRepository interface that all repositories implement, vs. each Repository having its own unique interface and set of methods. For example: a generic IRepository interface might look like (taken from this answer): public interface IRepository : IDisposable { T[] GetAll<T>(); T[] GetAll<T>(Expression<Func<T, bool>> filter); T GetSingle<T>(Expression<Func<T, bool>> filter); T GetSingle<T>(Expression<Func<T, bool>> filter, List<Expression<Func<T, object>>> subSelectors); void Delete<T>(T entity); void Add<T>(T entity); int SaveChanges(); DbTransaction BeginTransaction(); } Each Repository would implement this interface (e.g. CustomerRepository:IRepository, ProductRepository:IRepository, etc). The alternate that we've followed in prior projects would be: public interface IInvoiceRepository : IDisposable { EntityCollection<InvoiceEntity> GetAllInvoices(int accountId); EntityCollection<InvoiceEntity> GetAllInvoices(DateTime theDate); InvoiceEntity GetSingleInvoice(int id, bool doFetchRelated); InvoiceEntity GetSingleInvoice(DateTime invoiceDate, int accountId); //unique InvoiceEntity CreateInvoice(); InvoiceLineEntity CreateInvoiceLine(); void SaveChanges(InvoiceEntity); //handles inserts or updates void DeleteInvoice(InvoiceEntity); void DeleteInvoiceLine(InvoiceLineEntity); } In the second case, the expressions (LINQ or otherwise) would be entirely contained in the Repository implementation, whoever is implementing the service just needs to know which repository function to call. I guess I don't see the advantage of writing all the expression syntax in the service class and passing to the repository. Wouldn't this mean easy-to-messup LINQ code is being duplicated in many cases? For example, in our old invoicing system, we call InvoiceRepository.GetSingleInvoice(DateTime invoiceDate, int accountId) from a few different services (Customer, Invoice, Account, etc). That seems much cleaner than writing the following in multiple places: rep.GetSingle(x => x.AccountId = someId && x.InvoiceDate = someDate.Date); The only disadvantage I see to using the specific approach is that we could end up with many permutations of Get* functions, but this still seems preferable to pushing the expression logic up into the Service classes. What am I missing?

  • Why should I not wrap every block in "try"-"catch"?

    - by Konrad
    I have always been of the belief that if a method can throw an exception then it is reckless not to protect this call with a meaningful try block. I just posted 'You should ALWAYS wrap calls that can throw in try, catch blocks.' to this question and was told that it was 'remarkably bad advice' - I'd like to understand why. Thanks!

  • groovyx.net.ws.WSClient is having problems with ''soapenc:Array' Any workaround?

    - by ?????
    I'm trying to call a webservice (implemented with a .NET/ASP system) from groovy/grails using WSClient. I have no trouble accessing this service using the SOAPClient debugger (Todd Ditchendorf's program for OSX), but when i try it via groovy/grails, I get the error undefined simple or complex type 'soapenc:Array' Is there any solution? Looking at it with wireshark: It seems to have thrown this error even before it gets a chance to perform the transaction. The error is thrown right after WSClient has downloaded the second of two schemas referenced in he WSDL.

  • How do I programmatically convert mp3 to an itunes-playable aac/m4a file?

    - by kwork
    I've been looking for a way to convert an mp3 to aac programmatically or via the command line with no luck. Ideally, I'd have a snippet of code that I could call from my rails app that converts an mp3 to an aac. I installed ffmpeg and libfaac and was able to create an aac file with the following command: ffmpeg -i test.mp3 -acodec libfaac -ab 163840 dest.aac When i change the output file's name to dest.m4a, it doesn't play in iTunes. Thanks!

  • Adding objects to an NSMutableArray, order seems odd when parsing from an XML file

    - by diatrevolo
    Hello: I am parsing an XML file for two elements: "title" and "noType". Once these are parsed, I am adding them to an object called aMaster, an instance of my own Master class that contains NSString variables. I am then adding these instances to an NSMutableArray on a singleton, in order to call them elsewhere in the program. The problem is that when I call them, they don't seem to be on the same NSMutableArray index... each index contains either the title OR the noType element, when it should be both... can anyone see what I may be doing wrong? Below is the code for the parser. Thanks so much!! #import "XMLParser.h" #import "Values.h" #import "Listing.h" #import "Master.h" @implementation XMLParser @synthesize sharedSingleton, aMaster; - (XMLParser *) initXMLParser { [super init]; sharedSingleton = [Values sharedValues]; aMaster = [[Master init] alloc]; return self; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { aMaster = [[Master alloc] init]; //Extract the attribute here. if ([elementName isEqualToString:@"intro"]) { aMaster.intro = [attributeDict objectForKey:@"enabled"]; } else if ([elementName isEqualToString:@"item"]) { aMaster.item_type = [attributeDict objectForKey:@"type"]; //NSLog(@"Did find item with type %@", [attributeDict objectForKey:@"type"]); //NSLog(@"Reading id value :%@", aMaster.item_type); } else { //NSLog(@"No known elements"); } //NSLog(@"Processing Element: %@", elementName); //HERE } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else { [currentElementValue appendString:string];//[tempString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; CFStringTrimWhitespace((CFMutableStringRef)currentElementValue); } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"item"]) { [sharedSingleton.master addObject:aMaster]; NSLog(@"Added %@ and %@ to the shared singleton", aMaster.title, aMaster.noType); //Only having one at a time added... don't know why [aMaster release]; aMaster = nil; } else if ([elementName isEqualToString:@"title"]) { [aMaster setValue:currentElementValue forKey:@"title"]; } else if ([elementName isEqualToString:@"noType"]) { [aMaster setValue:currentElementValue forKey:@"noType"]; //NSLog(@"%@ should load into the singleton", aMaster.noType); } NSLog(@"delimiter"); NSLog(@"%@ should load into the singleton", aMaster.title); NSLog(@"%@ should load into the singleton", aMaster.noType); [currentElementValue release]; currentElementValue = nil; } - (void) dealloc { [aMaster release]; [currentElementValue release]; [super dealloc]; } @end

  • Setuptools not passing arguments for entry_points

    - by Austin
    I'm using setuptools for a Python script I wrote After installing, I do: $ megazord -i input -d database -v xx-xx -w yy-yy Like I would if I was running it ./like_this However, I get: Traceback (most recent call last): File "/usr/local/bin/megazord", line 9, in <module> load_entry_point('megazord==1.0.0', 'console_scripts', 'megazord')() TypeError: main() takes exactly 1 argument (0 given) Which looks like setuptools is not sending my arguments to main() to be parsed (by optparse) Here's my setuptools config for entry_points: entry_points = { 'console_scripts': [ 'megazord = megazord.megazord:main', 'megazord-benchmark = megazord.benchmark:main', 'megazord-hash = megazord.mzhash:main', 'megazord-mutate = megazord.mutator:main', ] } Any ideas?

  • Me.Invoke in VB.NET doesn't actually "Invoke" - threads stall on Invoke statement

    - by rwmnau
    I've got the following code: Public Delegate Sub SetStatusBarTextDelegate(ByVal StatusText As String) Private Sub SetStatusBarText(ByVal StatusText As String) If Me.InvokeRequired Then Me.Invoke(New SetStatusBarTextDelegate(AddressOf SetStatusBarText), StatusText) Else Me.labelScanningProgress.Text = StatusText End If End Sub The problem is that, when I call the "SetStatusBarText" sub from another thread, InvokeRequired is True (as it should be), but then my threads stall on the Me.Invoke statement - pausing execution shows them all just sitting there, not actually invoking anything. Any thoughts about why the threads seem to be afraid of the Invoke?

  • iPhone: How to purge a cached UITableViewCell

    - by iPhone dev
    iPhone SDK question: Does anyone have suggestions on how to purge a cached UITableViewCell I'd like to cache these cells with reuseIdentifier. However, there are times when I need to delete or modify some of the table rows. I expect to call reloadData after the row changes. Right now, dequeueReusableCellWithIdentifier always returns the cached(obsolete) entry from before. How do I indicate that the cache is stale and needs to be purged ?

    I have a script where I do not want it to call 'exit' if it's being sourced. Initially I though checking if $0 == bash but this has problems if the script is sourced from another script, or if the user sources it from ksh. Is there a reliable way of detecting if a script is being sourced?

    I am using mmap call to read from a very big file using simple pointer arithmetic in C++. The problem is that when I read small chunks of data (in the order of KBs) multiple times, each read take the same amount of time as the previous one. How can I know if the disk is being accessed to fulfill my request or whether the request is being fulfilled from main memory (page cache) in calls after the first one.
