  • Multi-accordion help (CSS issue maybe?)

    - by Josh
    So, I've been trying to develop this multi-accordion news section for this site. It's actually all working, thanks to an insightful plugin. I've modified it a little bit so it works as I want it to, but I've run into two issues, one which is possibly CSS. Issue #1: The idea for the user is that when they view this page, they see all the recent headlines. They can also see who it has been posted by and how many comments have been made to this article. If they wish, they can then click on the headline and the field will expand into the article. They can then either make a comment or view the comments via clicking the View Comments link or clicking the "number of comments" link in the "Posted by..." area (a shortcut to the comments basically). The problem I'm having is if I make the AUTHOR or the "0" comments a link, it breaks the accordion because the accordion uses an A CLASS to open it up. I'm looking for a fix, I've tried making it a H1 or a DIV but that also breaks it. Issue #2: This is a pretty picky one, but when you click the headline it expands, but at least in Firefox (haven't tested it in Chrome yet) the text jumps from the right and to the left, locking in place from which the CSS tells it to (padding-left). I don't know why it's exactly doing that, if anyone has any insight on that, it'd be appreciated. A two-parter to this issue is when you open the Headline to the article and then decide to close the article by clicking on the Headline, parts of the accordion jumps from the darker purple to the light purple before the task is finished. I'm also interested fixing this, but this issue in its entirety are all pretty nit picky things. You can view the demo of the site here: http://www.notedls.com/demo Please if anyone has any advice or fixes, I'd appreciate it, I've been trying to get this all to work to the best of my ability, but I'm clearly no guru or expert. Thanks!

  • Generating All Permutations of Character Combinations when # of arrays and length of each array are

    - by Jay
    Hi everyone, I'm not sure how to ask my question in a succinct way, so I'll start with examples and expand from there. I am working with VBA, but I think this problem is non language specific and would only require a bright mind that can provide a pseudo code framework. Thanks in advance for the help! Example: I have 3 Character Arrays Like So: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] I would like to generate ALL possible permutations of the character arrays like so: XA1 XA2 XA3 XA4 XB1 XB2 XB3 XB4 YA1 YA2 . . . ZB3 ZB4 This can be easily solved using 3 while loops or for loops. My question is how do I solve for this if the # of arrays is unknown and the length of each array is unknown? So as an example with 4 character arrays: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] Arr_4 = [a,b] I would need to generate: XA1a XA1b XA2a XA2b XA3a XA3b XA4a XA4b . . . ZB4a ZB4b So the Generalized Example would be: Arr_1 = [...] Arr_2 = [...] Arr_3 = [...] . . . Arr_x = [...] Is there a way to structure a function that will generate an unknown number of loops and loop through the length of each array to generate the permutations? Or maybe there's a better way to think about the problem? Thanks Everyone!

  • Combo box in a scrollable panel causing problems

    - by Dennis
    I have a panel with AutoScroll set to true. In it, I am programmatically adding ComboBox controls. If I add enough controls to exceed the viewable size of the panel a scroll bar appears (so far so good). However, if I open one of the combo boxes near the bottom of the viewable area the combo list isn't properly displayed and the scrollable area seems to be expanded. This results in all of the controls being "pulled" to the new bottom of the panel with some new blank space at the top. If I continue to tap on the drop down at the bottom of the panel the scrollable area will continue to expand indefinitely. I'm anchoring the controls to the left, right and top so I don't think anchoring is involved. Is there something obvious that could be causing this? Update: It looks like the problem lies with anchoring the controls to the right. If I don't anchor to the right then I don't get the strange behavior. However, without right anchoring the control gets cut off by the scroll bar. Here's a simplified test case I built that shows the issue: public Form1() { InitializeComponent(); Panel panel = new Panel(); panel.Size = new Size(80, 200); panel.AutoScroll = true; for (int i = 0; i < 10; ++i) { ComboBox cb = new ComboBox(); cb.Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top; cb.Items.Add("Option 1"); cb.Items.Add("Option 2"); cb.Items.Add("Option 3"); cb.Items.Add("Option 4"); cb.Location = new Point(0, i * 24); panel.Controls.Add(cb); } Controls.Add(panel); } If you scroll the bottom of the panel and tap on the combo boxes near the bottom you'll notice the strange behavior.

  • % style macros not supported in some C++/CLI project property pages under VS2010?

    - by Dave Foster
    We're currently evaluating VS2010 and have upgraded our VS2008 C++/CLI project to the new .vcxproj format. I've noticed that a certain property we had set in the project settings did not get translated properly. Under Configuration Properties - Managed Resources - Resource Logical Name, we used to have (in VS2008) the setting: $(IntDir)\$(RootNamespace).$(InputName).resources which indicated that all .resx files were to compile into OurLib.SomeForm.resources inside of the assembly. (the Debug portion is dropped when assembled) According to MSDN, the $(InputName) macro no longer exists and should be replaced with %(Filename). However, when translating the above line to swap those macros, it does not seem to ever expand. The second .resx file it tries to compile, I get a "LINK : fatal error LNK1316: duplicate managed resource name 'Debug\OurLib.%(Filename).resources". This indicates to me that the % style macros are not being expanded here, at least in this specific property. If we don't set anything in that property, the default behavior seems to be to add the subdirectory as a prefix, such as: OurLib.Forms.SomeForm.resources where Forms is the subdir of our project that the .resx file lives. This only occurs when the .resx file is in an immediate subdirectory of the project being built. If a .resx file exists somewhere else on disk (aka ..\OtherLib\Forms\SomeForm2.resx) this prefix is NOT added. This is causing an issue with loading form resources, as it does not account for this possible prefix, even though we are using the standard Forms Designer method of getting at resources: System::ComponentModel::ComponentResourceManager^ resources = (gcnew System::ComponentModel::ComponentResourceManager(SomeForm::typeid)); and do not specify the .resources file by name. The issue I've just described may not be the same as the original question, but if I were to fix the Resource Logical Name issue I think this would all go away. Does anyone have any information about these % macros and where they are allowed to be used?

  • Webstart omits cookie, resulting in EOFException in ObjectInputStream when accessing Servlets?!

    - by Houtman
    Hi, My app. is started from both the commandline and by using an JNLP file. Im running java version 1.6.0_14 First i had the problem that i created the Buffered input and output streams in incorrect order. Found the solution here at StackOverflow . So starting from the commandline works fine now. But when starting the app using Webstart, it ends here java.io.EOFException at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source) at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown Source) at java.io.ObjectInputStream.readStreamHeader(Unknown Source) at java.io.ObjectInputStream.<init>(Unknown Source) at <..>remoting.thinclient.RemoteSocketChannel.<init>(RemoteSocketChannel.java:76) I found some posts regarding similar problems; at ibm.com - identifies cookies problem at bugs.sun.com - identifies problem as solved in 6u10(b12)? The first suggests that there is a problem in Webstart with cookies. It doesn't seem to be acknowledged as a proper java bug though.. Still i am a bit lost in the solution provided regarding the cookies.(ibm link) Can anyone expand on the cookie solution? I can't find information on how the cookie is generated in the first place. Many thanks.

  • Custom Calculations in a Matrix - Reporting Services 2005

    - by bfrancis
    I am writing a report to show gas usage (in gallons) used by each department. The request is to view each month and the gallons used by each department. A column is required to display what each departments target goal is, based on the gallons of gas they have used in a past time frame. Each departments target goal is x percent less than the total gallons used for said time frame. I currently have a matrix in Reporting Services with departments making up rows, months making up columns, and gallons filling the details. The matrix is being filled by dataset1. I have the data grouping as is requested for each month by each department. My problem is calculating the target goal. My thought was to create a second dataset (dataset2) that returns the gallons used based on the time frame requested. I grouped this data by department. I was hoping I could use the department field in each dataset to make sure the appropriate numbers were used. I added a new column which shows up next to the gallons field. As I attempted to build the Expression I found out that I could only grab the gallons used from dataset2 if I was summing the gallons field. This gives me the total gallons used by every department combined. I have tried to find resources with similar examples of what I am trying to accomplish but I cannot seem to come across one. I am trying to keep this as detailed as possible without making it too wordy. I would be more than happy to clarify or explain into further detail what I have written above if it is needed. If anyone has links, comments, or suggestions they would be greatly appreciated. A very simple visual or what I am hoping to accomplish is below. The months and departments would expand based on the data returned. months ------------------------------ departments| gallons/month | target goal

  • slow SQL command

    - by Retrocoder
    I need to take some data from one table (and expand some XML on the way) and put it in another table. As the source table can have thousands or records which caused a timeout I decided to do it in batches of 100 records. The code is run on a schedule so doing it in batches works ok for the customer. If I have say 200 records in the source database the sproc runs very fast but if there are thousands it takes several minutes. I'm guessing that the "TOP 100" only takes the top 100 after it has gone through all the records. I need to change the whole code and sproc at some point as it doesn't scale but for now is there a quick fix to make this run quicker ? INSERT INTO [deviceManager].[TransactionLogStores] SELECT TOP 100 [EventId], [message].value('(/interface/mac)[1]', 'nvarchar(100)') AS mac, [message].value('(/interface/device) [1]', 'nvarchar(100)') AS device_type, [message].value('(/interface/id) [1]', 'nvarchar(100)') AS device_id, [message].value('substring(string((/interface/id)[1]), 1, 6)', 'nvarchar(100)') AS store_id, [message].value('(/interface/terminal/unit)[1]', 'nvarchar(100)') AS unit, [message].value('(/interface/terminal/trans/event)[1]', 'nvarchar(100)') AS event_id, [message].value('(/interface/terminal/trans/data)[1]', 'nvarchar(100)') AS event_data, [message].value('substring(string((/interface/terminal/trans/data)[1]), 9, 11)', 'nvarchar(100)') AS badge, [message].value('(/interface/terminal/trans/time)[1]', 'nvarchar(100)') AS terminal_time, MessageRecievedAt_UTC AS db_time FROM [deviceManager].[TransactionLog] WHERE EventId > @EventId --WHERE MessageRecievedAt_UTC > @StartTime AND MessageRecievedAt_UTC < @EndTime ORDER BY terminal_time DESC

  • Horizontally align rows in multiple tables using web user control

    - by goku_da_master
    I need to align rows in different tables that are layed out horizontally. I'd prefer to put the html code in a single web user control so I can create as many instances of that control as I want and lay them out horizontally. The problem is, the text in the rows needs to wrap. So some rows may expand vertically and some may not (see the example below). When that happens, the rows in the other tables aren't aligned horizontally. I know I can accomplish all this by using a single table, but that would mean I'd have to duplicate the name, address and phone html code instead of dynamically creating new instances of my user control (in reality there are many more fields than this, but I'm keeping it simple). Is there any way to do this whether with div's, tables or something else? Here's the problem: Mary Jane's address field expands 2 lines, causing her phone field to not align properly with John's and Bob's. Name: John Doe Name: Mary Jane Name: Bob Smith Address: 123 broadway Address: Some really long address Address: Short address Phone: 123-456 that takes up multiple lines Phone: 111-2222 Phone: 456-789 I'm not restricted in any way how to do this (other than using asp.net), but I'd prefer to use a single web control that I instantiate X times at design time (in this example, it's 3 times). I'm using VS2008, and .Net 3.5

  • How to copy an array of char pointers with a larger list of char pointers?

    - by Casey Link
    My function is being passed a struct containing, among other things, a NULL terminated array of pointers to words making up a command with arguments. I'm performing a glob match on the list of arguments, to expand them into a full list of files, then I want to replace the passed argument array with the new expanded one. The globbing is working fine, that is, g.gl_pathv is populated with the list of expected files. However, I am having trouble copying this array into the struct I was given. #include <glob.h> struct command { char **argv; // other fields... } void myFunction( struct command * cmd ) { char **p = cmd->argv; char* program = *p++; // save the program name (e.g 'ls', and increment to the first argument glob_t g; memset(&g, 0, sizeof(g)); int res = glob(*p, 0, NULL, &g); *p++ // increment while (*p) { glob(*p++, GLOB_APPEND, NULL, &g); // append the matches } // here i want to replace cmd->argv with the expanded g.gl_pathv memcpy(cmd->argv, g.gl_pathv, g.gl_pathc ); // this doesn't work globfree(&g); }

  • Get tag name and value of a given node using XMLReader, DOM, Xpath

    - by rossjha
    I need to query an xml document and then display specific tag values, e.g. forename, surname, group(dept), job_title. I'm using XMLReader as i may need to work with large XML files. I using DomXPath to filter the data, but i don't know how to retrieve the nodeName and value for each element. The code below only returns 'member' as the node name? Any help would be appreciated. <?php $reader = new XMLReader(); $reader->open('include/staff.xml'); while ($reader->read()){ switch($reader->nodeType){ case(XMLREADER::ELEMENT): if($reader->localName === 'staff'){ $node = $reader->expand(); $dom = new DomDocument(); $dom->formatOutput = true; $n = $dom->importNode($node, true); $dom->appendChild($n); $xp = new DomXpath($dom); $res = $xp->query("/staff/member[groups='HR']"); } } } echo $res->item(0)->nodeName; echo $res->item(0)->nodeValue; ?>

  • Conditional macro expansion

    - by Dave DeLong
    Heads up: This is a weird question. I've got some really useful macros that I like to use to simplify some logging. For example I can do Log(@"My message with arguments: %@, %@, %@", @"arg1", @"arg2", @"arg3"), and that will get expanded into a more complex method invocation that includes things like self, _cmd, __FILE__, __LINE__, etc, so that I can easily track where things are getting logged. This works great. Now I'd like to expand my macros to not only work with Objective-C methods, but general C functions. The problem is the self and _cmd portions that are in the macro expansion. These two parameters don't exist in C functions. Ideally, I'd like to be able to use this same set of macros within C functions, but I'm running into problems. When I use (for example) my Log() macro, I get compiler warnings about self and _cmd being undeclared (which makes total sense). My first thought was to do something like the following (in my macro): if (thisFunctionIsACFunction) { DoLogging(nil, nil, format, ##__VA_ARGS__); } else { DoLogging(self, _cmd, format, ##__VA_ARGS__); } This still produces compiler warnings, since the entire if() statement is substituted in place of the macro, resulting in errors with the self and _cmd keywords (even though they will never be executed during function execution). My next thought was to do something like this (in my macro): if (thisFunctionIsACFunction) { #define SELF nil #define CMD nil } else { #define SELF self #define CMD _cmd } DoLogging(SELF, CMD, format, ##__VA_ARGS__); That doesn't work, unfortunately. I get "error: '#' is not followed by a macro parameter" on my first #define. My other thought was to create a second set of macros, specifically for use in C functions. This reeks of a bad code smell, and I really don't want to do this. Is there some way I can use the same set of macros from within both Objective-C methods and C functions, and only reference self and _cmd if the macro is in an Objective-C method?

  • reddit style voting with django

    Hay i need to hand implemeneting a voting system into a model. I've had a huge helping hand from Mike DeSimone making this work in the first place, but i need to expand upon his work. Here is my current code View def show_game(request): game = Game.objects.get(pk=1) discussions = game.gamediscussion_set.filter(reply_to=None) d = { 'game':game, 'discussions':discussions } return render_to_response('show_game', d) Template <ul> {% for discussion in discussions %} {{ discussion.html }} {% endfor %} </ul> Model class GameDiscussion(models.Model): game = models.ForeignKey(Game) message = models.TextField() reply_to = models.ForeignKey('self', related_name='replies', null=True, blank=True) created_on = models.DateTimeField(blank=True, auto_now_add=True) userUpVotes = models.ManyToManyField(User, blank=True, related_name='threadUpVotes') userDownVotes = models.ManyToManyField(User, blank=True, related_name='threadDownVotes') def html(self): DiscussionTemplate = loader.get_template("inclusions/discussionTemplate") return DiscussionTemplate.render(Context({ 'discussion': self, 'replies': [reply.html() for reply in self.replies.all()] })) DiscussionTemplate <li> {{ discussion.message }} {% if replies %} <ul> {% for reply in replies %} {{ reply }} {% endfor %} </ul> {% endif %} </li> As you can see we have 2 fields userUpVotes and userDownVotes on the model, these will calculate how to order the discussions and replies. How would i implement these 2 fields to order the replies and discussions based on votes? Any help would be great!

  • SL3 TreeView Not Programmatically Scrolling

    - by Chris
    I have a treeview in Silverlight 3. The treeview is bound to a observable collection - which contains a list of hierarchical data. When the page loads initially, all nodes, by default, in the treeview, are collapsed. I have functionality that allows a certain item in the treeview to be selected programmatically. The problem that I am running into is when an item is selected that isn't immediately visible (i.e. one or more parent nodes are collapsed). I programmatically expand them, but, when I try to programmatically scroll into view, so the user can see the selected item, it doesn't work. I looked into this further, and I believe that it has to do with the calculated viewport height for the scroll viewer. It almost seems like a timing issue, as, if the item's parent node is expanded, and then the item is programmatically selected, the code that scrolls the treeview into view for that selected treeview item works perfectly. Please refer to the extension method below that I am using to scroll the treeview into view. Any help or suggestions on how to correct this would be greatly appreciated. Thanks. public static void BringIntoViewForScrollViewer(this FrameworkElement frameworkElement, ScrollViewer scrollViewer) { var transform = frameworkElement.TransformToVisual(scrollViewer); var positionInScrollViewer = transform.Transform(new Point(0, 0)); if (positionInScrollViewer.Y < 0 || positionInScrollViewer.Y > scrollViewer.ViewportHeight) scrollViewer.ScrollToVerticalOffset(scrollViewer.VerticalOffset + positionInScrollViewer.Y - ScrollPadding); }

  • how to prevent divs from overlapping when using no-wrap across table cells

    - by pedalpete
    I'm trying to create an events calendar which has a somewhat 'gantt' chart like bar representing the times of an event, along with the time listed. I've uploaded a page showing the problem As you can see, the problem is that in the 3rd cell, the event div is being overlapped by the previous event div which goes outside the boundary of the cell. The event from the 2nd cell SHOULD expand beyond the cell border, but what I'm trying to get to happen is that WHEN the event from the 2nd cell expands into the 3rd cell, the event on the 3rd cell starts a new line. I believe the problem exists because of the nowrap on the time, but I want the time and in some cases the bar to cross the cell boundary when the time goes from one day to another. All that works now, but I'm having a problem with events overlapping when an event goes from one day to another. I've tried all sorts of :even cells having a different padding, etc. but all these solutions seem to bring up more problems. Is there a way get the no-wrap to force a new long when it crosses into the next cell? or any other solution to this issue?

  • Removing an array dimension where the elements sum to zero

    - by James
    Hi, I am assigning a 3D array, which contains some information for a number of different loadcases. Each row in the array defines a particular loadcase (of which there are 3) and I would like to remove the loadcase (i.e. the row) if ALL the elements of the row (in 3D) are equal to zero. The code I have at the moment is: Array = zeros(3,5) % Initialise array Numloadcases = 3; Array(:,:,1) = [10 10 10 10 10; 0 0 0 0 0; 0 0 0 0 0;]; % Expand to a 3D array Array(:,:,2) = [10 10 10 10 10; 0 0 0 0 0; 0 0 0 0 0;]; Array(:,:,3) = [10 10 10 10 10; 0 0 0 0 0; 0 0 20 0 0;]; Array(:,:,4) = [10 10 10 10 10; 0 0 0 0 0; 0 0 20 0 0;]; % I.e. the second row should be removed. for i = 1:Numloadcases if sum(Array(i,:,:)) == 0; Array(i,:,:) = [] end end At the moment, the for loop I have to remove the rows causes an indexing error, as the size of the array changes in the loop. Can anyone see a work around for this? Thanks

  • Help understanding .NET delegates, events, and eventhandlers

    - by Seth Spearman
    Hello, In the last couple of days I asked a couple of questions about delegates HERE and HERE. I confess...I don't really understand delegates. And I REALLY REALLY REALLY want to understand and master them. (I can define them--type safe function pointers--but since I have little experience with C type languages it is not really helpful.) Can anyone recommend some online resource(s) that will explain delegates in a way that presumes nothing? This is one of those moments where I suspect that VB actually handicaps me because it does some wiring for me behind the scenes. The ideal resource would just explain what delegates are, without reference to anything else like (events and eventhandlers), would show me how all everything is wired up, explain (as I just learned) that delegates are types and what makes them unique as a type (perhaps using a little ildasm magic)). That foundation would then expand to explain how delegates are related to events and eventhandlers which would need a pretty good explanation in there own right. Finally this resource could tie it all together using real examples and explain what wiring DOES happen automatically by the compiler, how to use them, etc. And, oh yeah, when you should and should not use delegates, in other words, downsides and alternatives to using delegates. What say ye? Can any of you point me to resource(s) that can help me begin my journey to mastery? EDIT One last thing. The ideal resource will explain how you can and cannot use delegates in an interface declaration. That is something that really tripped me up. Thanks for your help. Seth

  • Chord Chart - Skip to key with a click

    - by Juan Gonzales
    I have a chord chart app that basically can transpose a chord chart up and down throughout the keys, but now I would like to expand that app and allow someone to pick a key and automatically go to that key upon a click event using a function in javascript or jquery. Can someone help me figure this out? The logic seems simple enough, but I'm just not sure how to implement it. Here are my current functions that allow the user to transpose up and down... var match; var chords = ['C','C#','D','D#','E','F','F#','G','G#','A','A#','B','C','Db','D','Eb','E','F','Gb','G','Ab','A','Bb','B','C']; var chords2 = ['C','Db','D','Eb','E','F','Gb','G','Ab','A','Bb','B','C','C#','D','D#','E','F','F#','G','G#','A','A#','C']; var chordRegex = /(?:C#|D#|F#|G#|A#|Db|Eb|Gb|Ab|Bb|C|D|E|F|G|A|B)/g; function transposeUp(x) { $('.chord'+x).each(function(){ ///// initializes variables ///// var currentChord = $(this).text(); // gatheres each object var output = ""; var parts = currentChord.split(chordRegex); var index = 0; ///////////////////////////////// while (match = chordRegex.exec(currentChord)){ var chordIndex = chords2.indexOf(match[0]); output += parts[index++] + chords[chordIndex+1]; } output += parts[index]; $(this).text(output); }); } function transposeDown(x){ $('.chord'+x).each(function(){ var currentChord = $(this).text(); // gatheres each object var output = ""; var parts = currentChord.split(chordRegex); var index = 0; while (match = chordRegex.exec(currentChord)){ var chordIndex = chords2.indexOf(match[0],1); //var chordIndex = $.inArray(match[0], chords, -1); output += parts[index++] + chords2[chordIndex-1]; } output += parts[index]; $(this).text(output); }); } Any help is appreciated. Answer will be accepted! Thank You

  • Targeted Simplify in Mathematica

    - by Timo
    I generate very long and complex analytic expressions of the general form: (...something not so complex...)(...ditto...)(...ditto...)...lots... When I try to use Simplify, Mathematica grinds to a halt, I am assuming due to the fact that it tries to expand the brackets and or simplify across different brackets. The brackets, while containing long expressions, are easily simplified by Mathematica on their own. Is there some way I can limit the scope of Simplify to a single bracket at a time? Edit: Some additional info and progress. So using the advice from you guys I have now started using something in the vein of In[1]:= trouble = Log[(x + I y) (x - I y) + Sqrt[(a + I b) (a - I b)]]; In[2]:= Replace[trouble, form_ /; (Head[form] == Times) :> Simplify[form],{3}] Out[2]= Log[Sqrt[a^2 + b^2] + (x - I y) (x + I y)] Changing Times to an appropriate head like Plus or Power makes it possible to target the simplification quite accurately. The problem / question that remains, though, is the following: Simplify will still descend deeper than the level specified to Replace, e.g. In[3]:= Replace[trouble, form_ /; (Head[form] == Plus) :> Simplify[form], {1}] Out[3]= Log[Sqrt[a^2 + b^2] + x^2 + y^2] simplifies the square root as well. My plan was to iteratively use Replace from the bottom up one level at a time, but this clearly will result in vast amount of repeated work by Simplify and ultimately result in the exact same bogging down of Mathematica I experienced in the outset. Is there a way to restrict Simplify to a certain level(s)? I realize that this sort of restriction may not produce optimal results, but the idea here is getting something that is "good enough".

  • [Cocoa] Core Animation with an NSView and subviews

    - by ndg
    I've subclassed NSView to create a 'container' view (which I've called TRTransitionView) which is being used to house two subviews. At the click of a button, I want to transition one subview out of the parent view and transition the other in, using the Core Animation transition type: kCATransitionPush. For the most part, I have this working as you'd expect (here's a basic test project I threw together). The issue I'm seeing relates to resizing my window and then toggling between my two views. After resizing a window, my subviews will appear at seemingly random locations within my TRTransitionView. Additionally, it appears as if the TRTransitionView hasn't stretched correctly and is clipping the contents of its subviews. Ideally, I would like subviews anchored to the top-left of their parent view at all times, and to also grow to expand the size of the parent view. The second issue relates to an NSTableView I've placed in my first subview. When my window is resized, and my TRTransitionView resizes to match its new dimensions, my TableView seems to resize its content quite awkwardly (the entire table seems to jolt around) and the newly expanded space that the table now occupies seems to 'flash' (as if in the process of being animated). Extremely difficult to describe, but is there any way to stop this? Here's my TRTransitionView class: -(void) awakeFromNib { [self setWantsLayer:YES]; [self addSubview:[self currentView]]; transition = [CATransition animation]; [transition setType:kCATransitionPush]; [transition setSubtype:kCATransitionFromLeft]; [self setAnimations: [NSDictionary dictionaryWithObject:transition forKey:@"subviews"]]; } - (void)setCurrentView:(NSView*)newView { if (!currentView) { currentView = newView; return; } [[self animator] replaceSubview:currentView with:newView]; currentView = newView; } -(IBAction) switchToViewOne:(id)sender { [transition setSubtype:kCATransitionFromLeft]; [self setCurrentView:viewOne]; } -(IBAction) switchToViewTwo:(id)sender { [transition setSubtype:kCATransitionFromRight]; [self setCurrentView:viewTwo]; }

  • C#'s equivalent to VB.Net's DirectCast?

    - by Collin Sauve
    This has probably been asked before, but if it has, I can't find it. Does C# have an equivalent to VB.Net's DirectCast? I am aware that it has () casts and the 'as' keyword, but those line up to CType and TryCast. To be clear, these keywords do the following; CType/() casts: If it is already the correct type, cast it, otherwise look for a type converter and invoke it. If no type converter is found, throw an InvalidCastException. TryCast/"as" keyword: If it is the correct type, cast it, otherwise return null. DirectCast: If it is the correct type, cast it, otherwise throw an InvalidCastException. EDIT: After I have spelled out the above, some people have still responded that () is equivalent, so I will expand further upon why this is not true. DirectCast only allows for either Narrowing or Widening conversions on inheritance tree, it does not support conversions across different branches like () does. ie: C#, this compiles and runs: //This code uses a type converter to go across an inheritance tree double d = 10; int i = (int)d; VB.Net, this does NOT COMPILE 'Direct cast can only go up or down a branch, never across to a different one. Dim d as Double= 10 Dim i as Integer = DirectCast(d, Integer) The equivalent in VB.Net to my C# code is CType: 'This compiles and runs Dim d as Double= 10 Dim i as Integer = CType(d, Integer) (Edit again, I was originally using strings, I changed it to double... sorry)

  • Partial Classes - are they bad design?

    - by dferraro
    Hello, I'm wondering why the 'partial class' concept even exists in .NET. I'm working on an application and we are reading a (actually very good) book relavant to the development platform we are implementing at work. In the book he provides a large code base /wrapper around the platform API and explains how he developed it as he teaches different topics about the platform development. Anyway, long story short - he uses partial classes, all over the place, as a way to fake multiple inheritence in C# (IMO). Why he didnt just split the classes up into multiple ones and use composition is beyond me. He will have 3 'partial class' files to make up his base class, each w/ 3-500 lines of code... And does this several times in his API. Do you find this justifiable? If it were me, I'd have followed the S.R.P. and created multiple classes to handle different required behaviors, then create a base class that has instances of these classes as members (e.g. composition). Why did MS even put partial class into the framework?? They removed the ability to expand/collapse all code at each scope level in C# (this was allowed in C++) because it was obviously just allowing bad habits - partial class is IMO the same thing. I guess my quetion is: Can you explain to me when there would be a legitimate reason to ever use a partial class? I do not mean this to be a rant / war thread. I'm honeslty looking to learn something here. Thanks

  • Jquery class changing works, but doesn't effect another function like it should

    - by Qwibble
    So I have content boxes that close and expand when you click an arrow. The content box has two classes for telling whether it is open or closed (.box_open, .box_closed). A hover function is assigned to box_open so when it is open and you hover over the header, the arrow appears. However, I don't want this to happen when the box is closed, as I want to arrow to remain visible when the box is closed. When the box closes, the box_open class is removed, but the function assigned to that class still works. Here's the jquery code for the two functions. You can also see them in the head of the demo below. // Display Arrow on Box Header Hover $(".box_open").hover( function () { $(this).find('a').show(); }, function () { $(this).find('a').hide(); } ); // Open and Close Boxes: $(".box_header a").click( function () { $(this).parent().next('.box_border').stop().toggle(); $(this).parent().toggleClass("box_open"); $(this).parent().toggleClass("box_closed"); return false; } ); Can anyone take a look at what the problem is? Here's the demo url: Demo Url

  • Adding XOR function to bigint library

    - by Jason Gooner
    Hi, I'm using this Big Integer library for Javascript: http://www.leemon.com/crypto/BigInt.js and I need to be able to XOR two bigInts together and sadly the library doesn't include such a function. The library is relatively simple so I don't think it's a huge task, just confusing. I've been trying to hack one together but not having much luck, would be very grateful if someone could lend me a hand. This is what I've attempted (might be wrong). But im guessing the structure is going to be quite similar to some of the other functions in there. function xor(x, y) { var c, k, i; var result = new Array(0); // big int for result k=x.length>y.length ? x.length : y.length; // array length of the larger num // Make sure result is the correct array size? maybe: result = expand(result, k); // ? for (c=0, i=0; i < k; i++) { // Do some xor here } // return the bigint xor result return result; } What confuses me is I don't really understand how it stores numbers in the array blocks for the bigInt. I don't think it's a case of simply bigintC[i] = bigintA[i] ^ bigintB[i], then most other functions have some masking operation at the end that I don't understand. I would really appreciate any help getting this working. Thanks

  • Remove padding in wxPython's wxWizard

    - by mridang
    Hi Guys, I'm using wxPython to create a wizard using the wxWizard control. I'm trying to a draw a colored rectangle but when I run the app, there seems to be a about a 10px padding on each side of the rectangle. This goes for all other controls too. I have to offset them a bit so that they appear exactly where I want them to. Is there any way I could remove this padding? Here's the source of my base Wizard page. class SimplePage(wx.wizard.PyWizardPage): """ Simple wizard page with unlimited rows of text. """ def __init__(self, parent, title): wx.wizard.PyWizardPage.__init__(self, parent) self.next = self.prev = None #self.sizer = wx.BoxSizer(wx.VERTICAL) title = wx.StaticText(self, -1, title) title.SetFont(wx.Font(18, wx.SWISS, wx.NORMAL, wx.BOLD)) #self.sizer.AddWindow(title, 0, wx.ALIGN_LEFT|wx.ALL, padding) #self.sizer.AddWindow(wx.StaticLine(self, -1), 0, wx.EXPAND|wx.ALL, padding) # self.SetSizer(self.sizer) self.Bind(wx.EVT_PAINT, self.OnPaint) def OnPaint(self, evt): """set up the device context (DC) for painting""" self.dc = wx.PaintDC(self) self.dc.BeginDrawing() self.dc.SetPen(wx.Pen("grey",style=wx.TRANSPARENT)) self.dc.SetBrush(wx.Brush("grey", wx.SOLID)) # set x, y, w, h for rectangle self.dc.DrawRectangle(0,0,500, 500) self.dc.EndDrawing() del self.dc def SetNext(self, next): self.next = next def SetPrev(self, prev): self.prev = prev def GetNext(self): return self.next def GetPrev(self): return self.prev def Activated(self, evt): """ Executed when page is being activated. """ return def Blocked(self, evt): """ Executed when page is about to be switched. Switching can be blocked by returning True.

  • How can I display multiple django modelformset forms together?

    - by JT
    I have a problem with needing to provide multiple model backed forms on the same page. I understand how to do this with single forms, i.e. just create both the forms call them something different then use the appropriate names in the template. Now how exactly do you expand that solution to work with modelformsets? The wrinkle, of course, is that each 'form' must be rendered together in the appropriate fieldset. For example I want my template to produce something like this: <fieldset> <label for="id_base-0-desc">Home Base Description:</label> <input id="id_base-0-desc" type="text" name="base-0-desc" maxlength="100" /> <label for="id_likes-0-icecream">Want ice cream?</label> <input type="checkbox" name="likes-0-icecream" id="id_likes-0-icecream" /> </fieldset> <fieldset> <label for="id_base-1-desc">Home Base Description:</label> <input id="id_base-1-desc" type="text" name="base-1-desc" maxlength="100" /> <label for="id_likes-1-icecream">Want ice cream?</label> <input type="checkbox" name="likes-1-icecream" id="id_likes-1-icecream" /> </fieldset> I am using a loop like this to process the results for base_form, likes_form in map(None, base_forms, likes_forms): which works as I'd expect (I'm using map because the # of forms can be different). The problem is that I can't figure out a way to do the same thing with the templating engine. The system does work if I layout all the base models together then all the likes models after wards, but it doesn't meet the layout requirements.
