  • Binding to NSTextField Cell not working, edited value resets to default

    - by cygnus6320
    I'm working on a Core Data document application that dynamically creates NSTableColumns. The data cell type may be a checkbox, slider, etc. Programmatically binding to all cell types works, except for NSTextFieldCell. All NSTextFieldCells fail to bind, and after editing they return to their default value. This happens no matter if they're binding to a string, a number (with an NSNumberFormatter applied), or a date (NSDateFormatter applied). I'm using the following format to do all bindings: NSDictionary *textFieldOpts = [NSDictionary dictionaryWithObjectsAndKeys:@"YES", NSContinuouslyUpdatesValueBindingOption, @"YES", NSValidatesImmediatelyBindingOption, nil]; [aCell bind:@"value" toObject:[[entryAC arrangedObjects] objectAtIndex:0] withKeyPath:@"numberData" options:textFieldOpts]; Again, these statements work if the cell type is anything but an NSTextFieldCell. I threw in an observeValueForKeyPath method to log when the value changes... and for other cell types (NSSliderCell for instance) I can see the value changing, but with the NSTextFieldCell, it never, ever updates. Help!

  • parse Linq To Xml with attribute nodes

    - by Manoj
    I am having xml with following structure <ruleDefinition appId="3" customerId = "acf"> <node alias="element1" id="1" name="department"> <node alias="element2" id="101" name="mike" /> <node alias="element2" id="102" name="ricky" /> <node alias="element2" id="103" name="jim" /> </node> </ruleDefinition> Here nodes are differentiated using alias and not with node tag. As you can see top level node element1 has same node name "node" as element2. I want to parse this XML based on attribute alias. What should be the Linq-To-Xml code (using C#)to acheive this?

  • Upload Image with Django Model Form

    - by jmitchel3
    I'm having difficulty uploading the following model with model form. I can upload fine in the admin but that's not all that useful for a project that limits admin access. #Models.py class Profile(models.Model): name = models.CharField(max_length=128) user = models.ForeignKey(User) profile_pic = models.ImageField(upload_to='img/profile/%Y/%m/') #views.py def create_profile(request): try: profile = Profile.objects.get(user=request.user) except: pass form = CreateProfileForm(request.POST or None, instance=profile) if form.is_valid(): new = form.save(commit=False) new.user = request.user new.save() return render_to_response('profile.html', locals(), context_instance=RequestContext(request)) #Profile.html <form enctype="multipart/form-data" method="post">{% csrf_token %} <tr><td>{{ form.as_p }}</td></tr> <tr><td><button type="submit" class="btn">Submit</button></td></tr> </form> Note: All the other data in the form saves perfectly well, the photo does not upload at all. Thank you for your help!

  • How can I extract a URL from a sentence that is in a NSString?

    - by 0SX
    What I'm trying to accomplish is as follows. I have a NSString with a sentence that has a URL within the sentience. I'm needing to be able to grab the URL that is presented within any sentence that is within a NSString so for example: Let's say I had this NSString NSString *someString = @"This is a sample of a http://abc.com/efg.php?EFAei687e3EsA sentence with a URL within it."; I need to be able to extract http://abc.com/efg.php?EFAei687e3EsA from within that NSString. This NSString isn't static and will be changing structure and the url will not necessarily be in the same spot of the sentence. I've tried to look into the three20 code but it makes no sense to me. How else can this be done? Thanks for help.

  • Explain BFS and DFS in terms of backtracking

    - by HH
    Wikipedia about DFS Depth-first search (DFS) is an algorithm for traversing or searching a tree, tree structure, or graph. One starts at the root (selecting some node as the root in the graph case) and explores as far as possible along each branch before backtracking. So is BFS? "an algorithm that choose a starting node, checks all nodes -- backtracks --, chooses the shortest path, chose neighbour nodes -- backtracks --, chose the shortest path -- finally finds the optimal path because of traversing each path due to continuos backtracking. Regex, find's pruning -- backtracking? The term backtracking confuseses due to its variety of use. UNIX find's pruning an SO-user explained with backtracking. Regex Buddy uses the term "catastrophic backtracking" if you do not limit the scope of your Regexes. It seems to be too wide umbrella-term. So: how do you define "Backtracking" GRAPH-theoretically? what is "backtracking" in BFS and DFS?

  • Style: Dot notation vs. message notation in Objective-C 2.0

    - by groundhog
    In Objective-C 2.0 we got the "dot" notation for properties. I've seen various back and forths about the merits of dot notation vs. message notation. To keep the responses untainted I'm not going to respond either way in the question. What is your thought about dot notation vs. message notation for property accessing? Please try to keep it focused on Objective-C - my one bias I'll put forth is that Objective-C is Objective-C, so your preference that it be like Java or JavaScript aren't valid. Valid commentary is to do with technical issues (operation ordering, cast precedence, performance, etc), clarity (structure vs. object nature, both pro and con!), succinctness, etc. Note, I'm of the school of rigorous quality and readability in code having worked on huge projects where code convention and quality is paramount (the write once read a thousand times paradigm).

  • Application creashing in saveAction of Coredata iphone sdk

    - by neha
    Hi all, In my application I'm inserting data using Coredata like this: GoodWork * newGoodwork = (GoodWork *)[NSEntityDescription insertNewObjectForEntityForName:@"GoodWork" inManagedObjectContext:self.managedObjectContext]; // Step 2: Set Properties [newGoodwork setEletitle:[NSString stringWithFormat:@"%@", aGoodwork.eletitle]]; [newGoodwork setEletxt:[NSString stringWithFormat:@"%@", aGoodwork.eletxt]]; [newGoodwork setSortId:[NSNumber numberWithInt:sortId]]; // Step 3: Save Object [self saveAction]; Everythinng is working fine but in saveAction which is: - (void)saveAction { NSError *error; if (![self.managedObjectContext save:&error]) { NSLog(@"Unresolved Core Data Save error %@, %@", error, [error userInfo]); exit(-1); } } My application is crashing after processing if condition. I'm not inserting all the fields in the entity "Goodwork". Can that be the reason? Thanx in advance.

  • Implementing Security on custom BCS/.net class?

    - by Michael Stum
    I'm implementing a custom BCS Model to get data from a backend system. As the backend uses it's own user management, I'm accessing it through a service account. All of this works well and allows me to pull data into SharePoint. However because it's channeled through the service account, everyone can access it, which is bad. Can anyone give me some tips which method to implement? The backend does not give me NT ACLs, but I wonder if I could just "fake" them somehow? (Essentially saying "This NT Group has Read Access" is good enough). I am aware of ISecurityTrimmer2 for Search Results, but ideally I want to cover security inside the BCS Model so that it applies to external lists as well. I want to avoid using Secure storage and mapping each individual user to the backend.

  • [C#] How to convert string encoded in windows-1250 to unicode ?

    - by Deveti Putnik
    Hi! I am receiving from some dll (which is wrapper for some external data source) strings in Windows-1250 codepage and I would like to insert them correctly (as unicode) to table in SQL Server Database. Since particular row in database which should hold that data is of NVarchar type, I only needed to convert it in my C# code to unicode and pass it as parameter. Everything is well and nice, but I stumbled on conversion step. I tried the following but that doesn't work: private static String getUnicodeValue(string string2Encode) // { Encoding srcEncoding = Encoding.GetEncoding("Windows-1250"); UnicodeEncoding dstEncoding = new UnicodeEncoding(); byte[] srcBytes = srcEncoding.GetBytes(string2Encode); byte[] dstBytes = dstEncoding.GetBytes(string2Encode); return dstEncoding.GetString(dstBytes); } When I insert this returned string to table, I don't get correct letters like Ð, d, C, c, C or c. Please, help! :)

  • Prototypejs .evalJSON not returning object

    - by Pselus
    I have this JSON (which validates according to JSONLint): [ { "BugCount":"2", "BugTitle":"C:\\INETPUB\\WWWROOT\\CLUBREADY2\\TRAINERS\\../Connections/LTC.asp", "ErrLine":"141", "BugID":"702" }, { "BugCount":"1", "BugTitle":"/admin/ajax_logagreementsig.asp", "ErrLine":"0", "BugID":"1322" }, ] However, when I run data = json.evalJSON on it I get some problems. If I run .evalJSON(true) (to sanitize) an error happens within prototype saying "json" is undefined. The same happens if I do .evalJSON(). If I do .evalJSON with no parenthesis, then data is just an empty object and no error happens. Is there something wrong with my JSON?

  • Using sed for introducing newline after each > in a +1 gigabyte large one-line text file

    - by wasatz
    I have a giant text file (about 1,5 gigabyte) with xml data in it. All text in the file is on a single line, and attempting to open it in any text editor (even the ones mentioned in this thread: http://stackoverflow.com/questions/159521/text-editor-to-open-big-giant-huge-large-text-files ) either fails horribly or is totally unusable due to the text editor hanging when attempting to scroll. I was hoping to introduce newlines into the file by using the following sed command sed 's/>/>\n/g' data.xml > data_with_newlines.xml Sadly, this caused sed to give me a segmentation fault. From what I understand, sed reads the file line-by-line which would in this case mean that it attempts to read the entire 1,5 gig file in one line which would most certainly explain the segfault. However, the problem remains. How do I introduce newlines after each in the xml file? Do I have to resort to writing a small program to do this for me by reading the file character-by-character?

  • Typecast to an int in Octave/Matlab

    - by Leif Andersen
    I need to call the index of a matrix made using the linspace command, and based on somde data taken from an oscilloscope. Because of this, the data inputed is a double. However, I can't really call: Time[V0Found] where V0Found is something like 5.2 however, taking index 5 is close enough, so I need to drop the decimal. I used this equation to drop the decimal: V0FoundDec = V0Found - mod(V0Found,1) Time[V0FoundDec] However, eve though that drops the decimal, octave still complains about it. So, what can I do to typecast it to an int? Thank you.

  • Is anyone else receiving a QUOTA_EXCEEDED_ERR on their iPad when accessing localStorage?

    - by Kevin
    I have a web application written in JavaScript that runs successfully on the desktop via Safari as well as on the iPhone. We are looking at porting this application to the iPad and we are running into a problem where we are seeing QUOTA_EXCEEDED_ERR when storing a relatively small amount of data within the localStorage on the device. I know what this error means, but I just don't think I'm storing all that much data. Is anyone else doing something similar? And seeing/not seeing this problem? Kevin...

  • MembershipProvider, IPrincipal, IIdentity?

    - by MRFerocius
    Hello guys; I have a conceptual question... I am making an Intranet application (Web platform) for a company. I have a SQL Server DB with these tables: Users (userID, userName, userPass, roleID) Roles (roleID, roleName) Pages (pageID, pageURL) RolesXPages(pageID, roleID) How is the best way to create a structure to store all this information while the user navigates the site, I mean, on the thread I should be able to check his role, his pages (the ones he can access) I have been reading and there is a lot of stuff there where Im confused, I saw the MembershipProvider, IPrincipal, IIdentity, etc classes but Im not sure what should be the best one for me. Any thoughts... Thanks in advance! Edit: Everytime gets more confusing... I just want to handle those structures at runtime and be able to mantain state during page callbacks or changing pages...

  • How do I reduce number of redundant requests with mod_perl properly?

    - by rassie
    In a fairly big legacy project, I've refactored several hairy modules into Moose classes. Each of these modules requires database access to (lazy) fetch its attributes. Since those objects are used pretty heavily, I want to reduce the number of redundant requests, for example for unchanged data. Now, how do I do that properly? I've got several alternatives: Implement caching in my Moose classes via a role to store them in memcached with expiration of 5-10 minutes (probably not too difficult, but tricky with lazy attributes) update: KiokuDB could probably help here, have to read up about attributes Migrate to DBIx::Class (needs to be done anyway) and implement caching on this level (DBIC will probably take most of the pain away just by itself) Somehow make my objects persist inside the mod_perl process (no clue how to do this :() How would you do this and what do you consider a sane way? Is caching data preferred on object or the ORM level?

  • IIS URL Rewriting for all Inbound URLs?

    - by Rob Burke
    Hopefully a simple question although one I have found impossible to answer myself using the Googles! I have a website on IIS with the URL http://www.contoso.com/ which points to C:\www\public\ There has been a forced directory restructure so now all of the data (Default.aspx, Product.aspx, etc.) that originally resided in C:\www\public\ now resides in C:\www\public\en\ie\ - however, the IIS website document root is still C:\www\public\ So, essentially, I have a lot of inbound links to http://www.contoso.com/Product.aspx?id=1 (etc.) which are now returning 404 errors - the correct link is now http://www.contoso.com/en/ie/Product.aspx?id=1 Please consider that I can make no changes to the directory structure or the IIS document root... so must solve this issue using URL rewriting. Is it possible to capture all requests to contoso.com/* and rewrite them to contoso.com/en/ie/* ??

  • How can I stop Silverlight DataForm immediately saving changes back to underlying object?

    - by Simon_Weaver
    I have a Silverlight master-details DataForm where the DataForm represents a street address. When I edit the Address1 textbox, the value gets automatically committed to the bound Address object once focus leaves the textbox. If I hit the Cancel button, then any changes are undone because Address implements IEditableObject and saves its state. The problem is that since any change is immediately propagated to the underlying object it will be shown in the master grid before the user has actually hit Save. I also have other locations where this data is shown. This is not a very good user experience. I've tried OneWay binding but then I can't commit back without manually copying all the fields over. The only thing I can think of doing is to create a copy of the data first or using OneWay binding, but they both seem a little clumsy. Does DataForm support this way of working?

  • Linking C and CXX files in CMake

    - by vedro so snegom
    Hi I'm building C++ app with CMake. But it uses some source files in C. Here is simplified structure: trunk/CMakeLists.txt: project(myapp) set(CMAKE_CXX_FLAGS "${CMAKE_C_FLAGS} -g -Wall") add_subdirectory (src myapp) trunk/src/main.cpp: #include "smth/f.h" int main() { f(); } trunk/src/CMakeLists.txt: add_subdirectory (smth) link_directories (smth) set(APP_SRC main) add_executable (myapp ${APP_SRC}) target_link_libraries (myapp smth) trunk/src/smth/f.h: #ifndef F_H #define F_H void f(); #endif trunk/src/smth/f.c: #include "f.h" void f() {} trunk/src/smth/CMakeLists.txt set (SMTH_SRC some_cpp_file1 some_cpp_file2 f) add_library (smth STATIC ${SMTH_SRC}) The problem is: i run gmake, it compiles all the files and when it links all libs together, i get: undefined reference to `f()` in main.cpp if i rename f.c into f.cpp everything goes just fine. What's the difference and how to handle it? Thanks

  • ffmpeg 0.5 flv to wav conversion creates wav files that other programs won't open.

    - by superrebel
    Hi, I am using the following command to convert FLV files to audio files to feed into julian, a speech to text program. cat ./jon2.flv | ffmpeg -i - -vn -acodec pcm_s16le -ar 16000 -ac 1 -f wav - | cat - > jon2.wav The cat's are there for debugging purposes as the final use will be a running program that will pipe FLV into ffmpeg's stdin and the stdout going to julian. The resulting wave files are identified by "file" as: jon3.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 16000 Hz VLC (based on ffmpeg) plays the file, but no other tools will open/see the data. They show empty wav files or won't open/play. For example Sound Booth from CS4. Has anyone else had similar problems? Julian requires wav files 16bit mono at 16000 Hz. Julian does seem to read the file, but doesn't seem to go through the entire file (may be unrelated). Thanks, -rr

  • How can I overwrite a System.Drawing.Bitmap onto an existing GDI bitmap?

    - by MusiGenesis
    If I have a .Net Bitmap, I can create from it a GDI bitmap by calling the Bitmap's GetHbitmap() method. Bitmap bmp = new Bitmap(100, 100); IntPtr gdiBmp = bmp.GetHbitmap(); This works fine, but every time you call GetHbitmap, Windows has to allocate new memory for the object that gdiBmp references. What I'd like to do - if possible - is write a function (I know PInvoke will be necessary here) that also generates a GDI bitmap copy of a Bitmap, but that uses an existing object instead of allocating a new one. So it would look something like this (if it were an extension method of Bitmap): //void OverwriteHbitmap(IntPtr gdi) Bitmap bmp1 = new Bitmap(100, 100); IntPtr gdi1 = bmp1.GetHbitmap(); Bitmap bmp2 = new Bitmap(100, 100); bmp2.OverwriteHbitmap(gdi1); How can I do this? I assume I'll need to know the structure of a GDI bitmap, and probably I can use LockBits and BitmapData for this, but I'm not sure exactly how.
