• Struct Array Initialization and String Literals

  - by Christian Ammer

  Is following array initialization correct? I guess it is, but i'm not really sure if i can use const char* or if i better should use std::string. Beside the first question, do the char pointers point to memory segments of same sizes? struct qinfo { const char* name; int nr; }; qinfo queues[] = { {"QALARM", 1}, {"QTESTLONGNAME", 2}, {"QTEST2", 3}, {"QIEC", 4} };

• how to send an array of bytes over a TCP connection (java programming)

  - by Mark Roberts

  Can somebody demonstrate how to send an array of bytes over a TCP connection from a sender program to a receiver program in Java. (I'm new to Java programming, and can't seem to find an example of how to do this that shows both ends of the connection (sender and receiver.) If you know of an existing example, maybe you could post the link. (No need to reinvent the wheel.) P.S. This is NOT homework! :-)

• Using Singleton synchronized array with NSThread

  - by hmthur

  I have a books app with a UISearchBar, where the user types any book name and gets search results (from ext API call) below as he types. I am using a singleton variable in my app called retrievedArray which stores all the books. @interface Shared : NSObject { NSMutableArray *books; } @property (nonatomic, retain) NSMutableArray *books; + (id)sharedManager; @end This is accessed in multiple .m files using NSMutableArray *retrievedArray; ...in the header file retrievedArray = [[Shared sharedManager] books]; My question is how do I ensure that the values inside retrievedArray remain synchronized across all the classes. Actually the values inside retrievedArray gets added through an NSXMLParser (i.e. through external web service API). There is a separate XMLParser.m file, where I do all the parsing and fill the array. The parsing is done on a separate thread. - (void) run: (id) param { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL: [self URL]]; [parser setDelegate: self]; [parser parse]; [parser release]; NSString *tmpURLStr = [[self URL]absoluteString]; NSRange range_srch_book = [tmpURLStr rangeOfString:@"v1/books"]; if (range_srch_book.location != NSNotFound) [delegate performSelectorOnMainThread:@selector(parseDidComplete_srch_book) withObject:nil waitUntilDone:YES]; [pool release]; } - (void) parseXMLFile: (NSURL *) url { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; [self setURL: url]; NSThread* myThread = [[NSThread alloc] initWithTarget:self selector:@selector(run:) object: nil]; [retrievedArray removeAllObjects]; [myThread start]; [pool release]; } There seems to be some synchronization issues if the user types very quickly (It seems to be working fine if the user types slowly)....So there are 2 views in which the content of an object in this shared array item is displayed; List and Detail. If user types fast and clicks on A in List view, he is shown B in detail view...That is the main issue. I have tried literally all the solutions I could think of, but am still unable to fix the issue. Please suggest some suitable fixes.

• Symfony 1.4: Storing an array in session with SetAttribute

  - by Tom

  Hi, I'm wondering if someone knows how to store an array into a user session? This is the method to store a single attribute: $this->getUser()->setAttribute('something', $something); And the documentation says: "User attributes can store any type of data (strings, arrays, and associative arrays)" ... but doesn't say anything more. The API documentation doesn't have a "SetAttributes" or something similarly obvious. Thank you.

  I know I can do for (id obj in array) { if ([obj isKindOfClass:[Elephant class]]) [elephants addObject:obj]; } but I feel there must be a more elegant way of doing this. I've looked at filtering arrays but can't come up with a good predicate. Thoughts?

• Across process marhalling problem with an array of points

  - by ElMagn

  Hi All, We have what we think is a marshalling problem with a renderer object when called across process boundaries. The renderer is an ATL COM server with a COM object that implements the IPoints interface defined below: typedef [uuid(B0E01719-005A-427c-B9DD-B42A18E969AE)] struct Point { double X; double Y; } Point; [ object, uuid(3BFECFE3-B4FB-4f14-8257-6E065D02E3B3), helpstring("IPoints Interface"), dual, ] interface IPoints : IDispatch { HRESULT DrawPolyLine([in] long hDC, [in] short count, [in, size_is(count)] Point * points ); // many more like DrawLine } The count parameter represents the number of points and the points parameter represents an array of the actual points. We have two process running, a graphical display process (GDP) and a tabular (grid) display process (TDP). A factory in the GDP, written in C#, creates the renderer and the clients of the renderer in the GDP. When the clients call into the renderer, everything displays correctly. The renderer is created at start up BTW. There is another factory in the TDP, written in VB6, that calls into the factory in the GDP to create the clients. When the clients call into the renderer, only the first point in the array is marshaled correctly, all the other points are garbage. Seems that the rendering works only when the client creation is started from the same process as the renderer. Now, i am not sure what the solution to this problem is. It seems that if we can guarantee that the clients are always created from a thread in the same GDP process as the renderer then the points are marshaled correctly. We tried using a background thread from the Thread Pool in C# and it indeed worked. The problem is that Windows Forms created from the clients stopped working because accessing the form's controls from a thread other than the thread that created the control is not allowed. We might change the calls to access the forms but we have quite a few of them and are trying to look into a different solution that might involve making changes to the renderer. The other problem is that the renderer is legacy code and we can't just change the interface. I am wondering what can we do to the renderer's interface that would help with marshalling from across process calls. Any ideas would be greatly appreciated. Regards, ElMagn
