  • Rich Text Editor with Tab and Table Support

    - by Chris W.
    We are developing a project for a client that requires a rich text editor that supports both tables and "real" tabs for indentation. Of the editors we've looked at, both TinyMCE and FreeRichTextEditor are very close fits, but indenting with tab seems to only work in WebKit-based browsers. Is there a (preferably free) cross-browser compatible rich text editor that supports both of these features, or a way of 'fixing' tab support in Trident and Mozilla-based browsers?

  • C Programming - My program is good enough for my assignment but I know its not good

    - by Joe
    Hi there I'm just starting an assignment for uni and it's raised a question for me. I don't understand how to return a string from a function without having a memory leak. char* trim(char* line) { int start = 0; int end = strlen(line) - 1; /* find the start position of the string */ while(isspace(line[start]) != 0) { start++; } //printf("start is %d\n", start); /* find the position end of the string */ while(isspace(line[end]) != 0) { end--; } //printf("end is %d\n", end); /* calculate string length and add 1 for the sentinel */ int len = end - start + 2; /* initialise char array to len and read in characters */ int i; char* trimmed = calloc(sizeof(char), len); for(i = 0; i < (len - 1); i++) { trimmed[i] = line[start + i]; } trimmed[len - 1] = '\0'; return trimmed; } as you can see I am returning a pointer to char which is an array. I found that if I tried to make the 'trimmed' array by something like: char trimmed[len]; then the compiler would throw up a message saying that a constant was expected on this line. I assume this meant that for some reason you can't use variables as the array length when initialising an array, although something tells me that can't be right. So instead I made my array by allocating some memory to a char pointer. I understand that this function is probably waaaaay sub-optimal for what it is trying to do, but what I really want to know is: 1. Can you normally initialise an array using a variable to declare the length like: char trimmed[len]; ? 2. If I had an array that was of that type (char trimmed[]) would it have the same return type as a pointer to char (ie char*). 3. If I make my array by callocing some memory and allocating it to a char pointer, how do I free this memory. It seems to me that once I have returned this array, I can't access it to free it as it is a local variable. Many thanks in advance Joe

  • Objective-C: properties not being saved or passed

    - by Gerald Yeo
    Hi, i'm a newbie to iphone development. I'm doing a navigation-based app, and I'm having trouble passing values to a new view. @interface RootViewController : UITableViewController { NSString *imgurl; NSMutableArray *galleryArray; } @property (nonatomic, retain) NSString *imgurl; @property (nonatomic, retain) NSMutableArray *galleryArray; - (void)showAll; @end #import "RootViewController.h" #import "ScrollView.h" #import "Model.h" #import "JSON/JSON.h" @implementation RootViewController @synthesize galleryArray, imgurl; - (void)viewDidLoad { UIBarButtonItem *showButton = [[[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Show All", @"") style:UIBarButtonItemStyleBordered target:self action:@selector(showAll)] autorelease]; self.navigationItem.rightBarButtonItem = showButton; NSString *jsonString = [[Model sharedInstance] jsonFromURLString:@"http://www.ddbstaging.com/gerald/gallery.php"]; NSDictionary *resultDictionary = [jsonString JSONValue]; if (resultDictionary == nil) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Webservice Down" message:@"The webservice you are accessing is currently down. Please try again later." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; } else { galleryArray = [[NSMutableArray alloc] init]; galleryArray = [resultDictionary valueForKey:@"gallery"]; imgurl = (NSString *)[galleryArray objectAtIndex:0]; NSLog(@" -> %@", galleryArray); NSLog(imgurl); } } - (void)showAll { NSLog(@" -> %@", galleryArray); NSLog(imgurl); ScrollView *controller = [[ScrollView alloc] initWithJSON:galleryArray]; [self.navigationController pushViewController:controller animated:YES]; } The RootViewController startup and the json data loads up fine. I can see it from the first console trace. However, once I click on the Show All button, the app crashes. It doesn't even trace the galleryArray and imgurl properyly. Maybe additional pairs of eyes can spot my mistakes. Any help is greatly appreciated!

    I am looking into JSON RPC libraries for .net that are free to use in commercial applications. Up until now i just seem to have found JROCK. What other libraries, architecture have i got similar to JRock for .NET 2.0 What is the difference between a [WebMethod] in asmx web-service returning a instance of a class and a JSON Rpc method as in the JRock website page. Do i have any usability benefits, performance benefits or any benefits of using one over the other

  • Marshal.PtrToStructure (and back again) and generic solution for endianness swapping

    - by cgyDeveloper
    I have a system where a remote agent sends serialized structures (from and embedded C system) for me to read and store via IP/UDP. In some cases I need to send back the same structure types. I thought I had a nice setup using Marshal.PtrToStructure (receive) and Marshal.StructureToPtr (send). However, a small gotcha is that the network big endian integers need to be converted to my x86 little endian format to be used locally. When I'm sending them off again, big endian is the way to go. Here are the functions in question: private static T BytesToStruct<T>(ref byte[] rawData) where T: struct { T result = default(T); GCHandle handle = GCHandle.Alloc(rawData, GCHandleType.Pinned); try { IntPtr rawDataPtr = handle.AddrOfPinnedObject(); result = (T)Marshal.PtrToStructure(rawDataPtr, typeof(T)); } finally { handle.Free(); } return result; } private static byte[] StructToBytes<T>(T data) where T: struct { byte[] rawData = new byte[Marshal.SizeOf(data)]; GCHandle handle = GCHandle.Alloc(rawData, GCHandleType.Pinned); try { IntPtr rawDataPtr = handle.AddrOfPinnedObject(); Marshal.StructureToPtr(data, rawDataPtr, false); } finally { handle.Free(); } return rawData; } And a quick example structure that might be used like this: byte[] data = this.sock.Receive(ref this.ipep); Request request = BytesToStruct<Request>(ref data); Where the structure in question looks like: [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)] private struct Request { public byte type; public short sequence; [MarshalAs(UnmanagedType.ByValArray, SizeConst = 5)] public byte[] address; } What (generic) way can I swap the endianness when marshalling the structures? My need is such that the locally stored 'public short sequence' in this example will be little-endian for displaying to the user. I don't want to have to swap the endianness on a structure-specific way. My first thought was to use Reflection, but I'm not very familiar with that feature. Also, I hoped that there would be a better solution out there that somebody could point me towards. Thanks in advance :)

  • Pygame Font not consistent

    - by Smashery
    I'm working on a program in python+pygame with some other developers, and we're seeing the same font rendered differently. It's a free font that we're distributing with the game. On my machine, this particular font is rendering 10px lower than on another developer's machine. Any thoughts on why this is?

  • tableSorter limitation (sort) one page at a time?

    - by Abu Hamzah
    i see that in tableSorter you can sort one page at a time which concerns me. Only 1 page of results can be sorted at a time?, which is pretty limiting. If you have a query result that spans multiple pages, how you will handle this? If anyone knows better, feel free to correct me if iam incorrect Thanks.

  • Silverlight Marching Ants Image Selection

    - by Ben Herila
    (Silverlight 3) Is there a pre-existing (preferably free, even better if open source) method (either a control or source code) for dragging a "marching ants" style selection on an image in a ScrollViewer or on a Canvas, similar to how it's done in image editing software? Even better if the resulting selection box has adjustment handles.
