  • Is there a way to serialize a .Net MailMessage object

    - by Matt Dawdy
    I am trying to write a proc that will take in as a parameter a MailMessage object, and the split it apart to store the subject, body, to addresses, from address, and attachments (the hard part) in a database so the email can be sent at some point in the future. My first take on this was to rip out the parts I need and store them in a database, and that works great except for attachments. I can't figure out how to loop through the collection and then actually do anything with them. It there an easy way to serialize a MailMessage object that will actually take the content of the attachments with it? Am I doing this all wrong? Has anyone done this before?

  • iPad: SplitView does not rotate

    - by raj.tiwari
    I have the following setup: A subclass of UISplitViewController that creates the master and detail view controllers in the constructor. Master and Detail view controllers that both override shouldAutorotateToInterfaceOrientation to return `YES'. Detail view controller implements the UISplitViewControllerDelegate protocol and deals with the popover. I am observing two weird issues that might be interrelated: When the split view comes up (in portrait mode - default on simulator), the Master view is visible. It should not be. When I rotate the simulator, the view does not "right" itself. My UISplitViewController subclass does not override shouldAutorotateToInterfaceOrientation. However, both master and details view controllers do and return YES. Any ideas what I might be doing wrong? Is this a simulator bug? Thanks. -Raj

  • Prevent Python from caching the imported modules

    - by Olivier
    While developing a largeish project (split in several files and folders) in Python with IPython, I run into the trouble of cached imported modules. The problem is that instructions import module only reads the module once, even if that module has changed! So each time I change something in my package, I have to quit and restart IPython. Painful. Is there any way to properly force reloading some modules? Or, better, to somehow prevent Python from caching them? I tried several approaches, but none works. In particular I run into really, really weird bugs, like some modules or variables mysteriously becoming equal to None... The only sensible resource I found is Reloading Python modules, from pyunit, but I have not checked it. I would like something like that. A good alternative would be for IPython to restart, or restart the Python interpreter somehow. So, if you develop in Python, what solution have you found to this problem?

  • How to print WPF Grid paged?

    - by Oliver Hanappi
    Hi! I'm printing a WPF grid. As long as the data fits on one page, everything works fine. But sometimes the grid contains more data. Therefore I need to split the grid into multiple pages. Can anybody help me? My code looks like this (visual is the grid). var printCapabilities = printDialog.PrintQueue.GetPrintCapabilities(printDialog.PrintTicket); var size = new Size(printCapabilities.PageImageableArea.ExtentWidth, printCapabilities.PageImageableArea.ExtentHeight); visual.Measure(size); visual.Arrange(new Rect(new Point(printCapabilities.PageImageableArea.OriginWidth, printCapabilities.PageImageableArea.OriginHeight), size)); printDialog.PrintVisual(visual, "Print ListView"); Should I try another control? I've tried WPF Toolkit DataGrid, but I couldn't manage to get it printed. I've heard something of a flow document, can this help me? Best Regards Oliver Hanappi

  • Space partitioning algorithm

    - by Karol Kolenda
    I have a set of points which are contained within the rectangle. I'd like to split the rectangles into subrectangles based on point density (giving a number of subrectangles or desired density, whichever is easiest). The partitioning doesn't have to be exact (almost any approximation better than regular grid would do), but the algorithm have to cope with the large number of points - approx. 200 millions. The desired number of subrectangles however is substantially lower (around 1000). Does anyone knows any algorithm which may help me with this particular task?

  • JavaScript - get detailed information about the browser

    - by iconiK
    Basically I'm looking for something to give me easy access to information like useragentstring.com, but in JS, without me parsing the user agent and looking for each possible bit of text. The object could be something like this: browser = UserAgent.Browser; // Chrome browserVer = UserAgent.BrowserVersion; // 5.0.342.9 os = UserAgent.OperatingSystem; // Windows NT osVer = UserAgent.OperatingSystemVersion; // 6.1 layoutEng = UserAgent.LayoutEngine; // WebKit layoutEngVer = UserAgent.LayoutEngineVersion; // 533.2 Does something similar to that exist or do I have to write one myself? Writing yet another user agent parser doesn't seem that easy with all those impersonations going back to the dark ages of the web. Specifically I'm looking for something that doesn't just split the user agent into parts and give them to me, because that's as useless as the user agent itself; instead it should parse the user agent and recognize the engine, browser, OS, etc. and return the concrete parts only, as in the example.

  • how to parse a Date string to java.Date

    - by hguser
    Hi: I have a date string and I wang to parse it to normal date use the java Date API,the following is my code: public static void main(String[] args) { String date="2010-10-02T12:23:23Z"; String pattern="yyyy-MM-ddThh:mm:ssZ"; SimpleDateFormat sdf=new SimpleDateFormat(pattern); try { Date d=sdf.parse(date); System.out.println(d.getYear()); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } However I got a exception:java.lang.IllegalArgumentException: Illegal pattern character 'T' So I wonder if i have to split the string and parse it manually? BTW, I have tried to add a single quote character on either side of the T: String pattern="yyyy-MM-dd'T'hh:mm:ssZ"; It also does not work.

  • ExtJS - Save State of treePanel.

    - by Ozaki
    TLDR I want my treepanel from EXTJS to remember its previous settings. ExtJS-3.2.1 I have seen this done before for ExtJS-2.x.x :See here on the extjs forums. But as seen as they are pretty much lifeless, with threads on there asking this question or similar with no reply for up to 6months. I thought I would bring it here. I need to be able to get my treePanel to remember previous opened folders and which boxes are checked. It is async treePanel. Panel is as follows: var layerTree = new Ext.tree.TreePanel({ border: true, region: "east", title: 'LayersTree', width: 250, split: true, collapsible: true, collapsed: true, iconCls: 'treePanelIcon', enableDD: true, autoScroll: true, //pulls in layers and their attributes// root: new Ext.tree.AsyncTreeNode({ leaf: false, loaded: false, expanded: true, text: 'Tree Root', children: treeLayers }) Am using ExtJS-3.2.1, GeoExt, OpenLayers. Anyone done this before or know how to do it? (Preferably with a plugin but any answer is appreciated)

  • Linq: convert string to int array

    - by Oops
    I have a function (tointarray) to convert a string into an array of ints, but I am not very satisfied with it. it does the job but there must be a more elegant way to do this, perhaps Linq could help here. unfortunately I am not very good in Linq. do you guys know a better way? my function: { string s1 = "1;2;3;4;5;6;7;8;9;10;11;12"; int[] ia = tointarray(s1, ';'); } int[] tointarray(string value, char sep) { string[] sa = value.Split(sep); int[] ia = new int[sa.Length]; for (int i = 0; i < ia.Length; ++i) { int j; string s = sa[i]; if (int.TryParse(s, out j)) { ia[i] = j; } } return ia; }

  • iPad UISplitView initial state in portrait: how to display popover controller widget?

    - by Patrick Linskey
    Hi, I'm working on an iPad app that uses a UISplitView. Inspired by http://blog.blackwhale.at/2010/04/your-first-ipad-split-view-application/, I display a button in my detail view when in portrait mode that shows the popover controller. This works great. However, the appropriate UISplitViewControllerDelegate message is only sent when the device rotates. So, when the app first loads (in portrait mode), my navigation button is not visible. Is it possible to somehow convince the UISplitViewController to send that message on load or something, or do I need to re-implement my own popover logic to get things working? Thanks, -Patrick

  • OData and custom WCF WebGet methods

    - by reinier
    I've created an OData endpoint (using entity framework, WCF data service) and added a custom test WebGet test method like so: [WebGet(UriTemplate = "{text}")] public IQueryable<string> SplitString(string text) { if (text == null) throw new DataServiceException("text not specified"); var result = (from s in text.Split('-') orderby s select s); return result.AsQueryable(); } and a config line: config.SetServiceOperationAccessRule("SplitString", ServiceOperationRights.All); However, no matter how I specify the url, I can not get the text param to be filled out. (it is always null). so: http://localhost/myservice.svc/SplitString/testtext does not work. What is the correct url format (or UriTemplate) one should use? The only examples I found of odata and WebGet only have an example method which doesn't have any parameters.

  • Forcing a mixed ISO-8859-1 and UTF-8 multi-line string into UTF-8

    - by knorv
    Consider the following problem: A multi-line string $junk contains some lines which are encoded in UTF-8 and some in ISO-8859-1. I don't know a priori which lines are in which encoding, so heuristics will be needed. I want to turn $junk into pure UTF-8 with proper re-encoding of the ISO-8859-1 lines. Also, in the event of errors in the processing I want to provide a "best effort result" rather than throwing an error. My current attempt looks like this: $junk = &force_utf8($junk); sub force_utf8 { my $input = shift; my $output = ''; foreach my $line (split(/\n/, $input)) { if (utf8::valid($line)) { utf8::decode($line); } $output .= "$line\n"; } return $output; } While this appears to work I'm certain this is not the optimal solution. How would you improve my force_utf8(...) sub?

  • Embedded Glassfish - logging

    - by Walter White
    Hi all, I have migrated from log4j to logback and also am transitioning to Glassfish from Jetty. I haven't updated my logback configuration from what I had used with Jetty and consequently am not seeing any logs being written. What logging provider should I use? Should I just do my configuration with the Glassfish loggers in domain.xml? <access-log rotation-interval-in-minutes="15" rotation-suffix="yyyy-MM-dd"/> <log-service file="${com.sun.aas.instanceRoot}/logs/server.log" log-rotation-limit-in-bytes="2000000"> <module-log-levels/> </log-service> These are the defaults in domain.xml. I'd like to split the longs up into several files as well as control log level for each package. I think I can figure out how to configure them, but should I use Glassfish logging or can I use logback? Walter

  • Dismissing iPad UIPopoverController when BarButtonItem is pushed while it's open

    - by joshholat
    Using a split view on the iPad, I have the following code: - (void)splitViewController: (UISplitViewController*)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem*)barButtonItem forPopoverController:(UIPopoverController*)pc { barButtonItem.title = @"Categories"; NSMutableArray *items = [[toolbar items] mutableCopy]; [items insertObject:barButtonItem atIndex:0]; [toolbar setItems:items animated:YES]; [items release]; self.popoverController = pc; } This works well to show the popover when the button is pressed. However, I'd also like to have the popover dismiss if the button is pressed while it is already open to follow good guidelines. How would I go about doing this? (i.e. if the user repeatedly clicks this button, the popover should come and hide every other hit.)

  • How can I set the Inital Orientation for a UISplitViewCOntroller-based iPad App

    - by MystikSpiral
    I have a split view app running fine on the iPad. It is using the default setup (Popover in Portrait, table view on the left in landscape). The views shift correctly once the app is running. The problem I am seeing is that when the app starts (in the simulator) running in landscape mode the UI paradigm is the one intended for Portrait mode (Master List is a popover) is what loads. I am thinking this is some strangeness with the simulator, or I am missing an option on my main view controller.

  • problem with hand tracking, opencv

    - by JP Talusan
    I am currently creating an opencv program that identifies a hand in an image and then gets the contour of the hand only, in order for us to get the center (x,y)m in pixels, of the hand. The problem is that whenever the image or video includes an arm or a face, we can't split or separate the hand from the contours of the arm or the face. We are currently using an HSV flesh colored histogram to get the contours of the hand. is there a way to separate them, i just need the hand. also if the picture includes only a hand and some part of the arm. How can we isolate the palm itself from the rest of the picture. all we need is a clear center of the palm. thanks in advanced.

  • IoC container configuration

    - by nivlam
    How should the configuration for an IoC container be organized? I know that registering by code should be placed at the highest level in an application, but what if an application had hundreds of dependencies that need to be registered? Same with XML configurations. I know that you can split up the XML configurations into multiple files, but that would seem like it would become a maintenance hassle if someone had to dig through multiple XML files. Are there any best practices for organizing the registration of dependencies? From all the videos and tutorials that I've seen, the code used in the demo were simple enough to place in a single location. I have yet to come across a sample application that utilizes a large number of dependencies.

  • Ext JS how to tell PagingToolbar to use parent Grid storage?

    - by Nazariy
    I'm trying to build application that use single config passed by server as non native JSON (can contain functions). Everything works fine so far but I'm curious why PagingToolbar does not have an option to use parent Grid store? I have tried to set store in my config like this, but without success: {... store:Ext.StoreMgr.lookup('unique_store_id') } Is there any way to do so without writing tons of javascript for each view defining store, grid and other items in my application or at least extend functionality of PaginationToolbar that use options from parent object? UPDATED, Here is short example of server response (minified) { "xtype":"viewport", "layout":"border", "renderTo":Ext.getBody(), "autoShow":true, "id":"mainFrame", "defaults":{"split":true,"useSplitTips":true}, "items":[ {"region":"center", "xtype":"panel", "layout":"fit", "id":"content-area", "items":{ "id":"manager-panel", "region":"center", "xtype":"tabpanel", "activeItem":0, "items":[ { "xtype":"grid", "id":"domain-grid", "title":"Manage Domains", "store":{ "xtype":"arraystore", "id":"domain-store", "fields":[...], "autoLoad":{"params":{"controller":"domain","view":"store"}}, "url":"index.php" }, "tbar":[...], "bbar":{ "xtype":"paging", "id":"domain-paging-toolbar", "store":Ext.StoreMgr.lookup('domain-store') }, "columns":[...], "selModel":new Ext.grid.RowSelectionModel({singleSelect:true}), "stripeRows":true, "height":350, "loadMask":true, "listeners":{ "cellclick":activateDisabledButtons } } ] }, } ] }

  • How to implement full text search in Django?

    - by Jannis
    I would like to implement a search function in a django blogging application. The status quo is that I have a list of strings supplied by the user and the queryset is narrowed down by each string to include only those objects that match the string. See: if request.method == "POST": form = SearchForm(request.POST) if form.is_valid(): posts = Post.objects.all() for string in form.cleaned_data['query'].split(): posts = posts.filter( Q(title__icontains=string) | Q(text__icontains=string) | Q(tags__name__exact=string) ) return archive_index(request, queryset=posts, date_field='date') Now, what if I didn't want do concatenate each word that is searched for by a logical AND but with a logical OR? How would I do that? Is there a way to do that with Django's own Queryset methods or does one have to fall back to raw SQL queries? In general, is it a proper solution to do full text search like this or would you recommend using a search engine like Solr, Whoosh or Xapian. What are there benefits? Thanks for taking the time

  • Mustache.js render technique

    - by PanosJee
    Hello everyone, i am trying to use mustache.js to render some JSON in the browser. What i want to do is: <li> <span class="label">Location: </span> {{#locations}} {{.}}<span class="social-small-size "></span> {{/locations}} </li> The locations is a js array [["Pendéli, Attiki, Greece", "facebook"], ["Greece", "linkedin"]] Initially i tried to use {{%IMPLICIT-ITERATOR iterator=loc}} in my attempt to split the data in the view. So i the actual rendering code was {{loc[0]}}<span class="social-small-size {{loc[1}}"></span> But that did n t work altough the loop worked and i got 2 spans but without any content. I think the PRAGMA is what I need but I didn 't figure it out. Any hints ? :)

  • External SWF to External SWF Timeline Communication, Flash, AS2

    - by jecca411
    Flash CS4, AS2 I have made an interactive tour. It can be seen here: http://www.92YTribeca.org/Tour click on the bottom image Each of the 4 sections are external swf and loaded on level 1. I want a button on one swf (floorplan) to load another swf (facility rentals) AND pinpoint a specific frame on the swf's timeline. I have tried many different ways, all end up loading the swf at the first frame and ignore the rest of the code talking about the timeline. I know I could split this swf up into more external swfs and get the result I want, but I would rather use code if I can. Is what I want to do possible? If so, how do I write the code? Thanks!

  • Spawning BackgroundWorkers

    - by washtik
    We have a business case that would be perfect for multiple BackgroundWorkers. As an example, we have a form with a "Save" button on it. Normally we would run all the save commands (Save is an example) synchronously and then close the form. We would like to now split the work onto separate threads using backgroundworker. We will loop through each "Save" required (could be many and/or different number of commands that need executing) creating a BackgroundWorker for each command required. The question is ... how do we wait for ALL the BackgroundWorkers to complete before we close the form. We understand how to wait for a single BackgroundWorker to complete but when we have X number of BackgroundWorkers operating, how do we wait until all are complete before closing the UI form?

  • Building a directory tree from a list of file paths

    - by Abignale
    I am looking for a time efficient method to parse a list of files into a tree. There can be hundreds of millions of file paths. The brute force solution would be to split each path on occurrence of a directory separator, and traverse the tree adding in directory and file entries by doing string comparisons but this would be exceptionally slow. The input data is usually sorted alphabetically, so the list would be something like: C:\Users\Aaron\AppData\Amarok\Afile C:\Users\Aaron\AppData\Amarok\Afile2 C:\Users\Aaron\AppData\Amarok\Afile3 C:\Users\Aaron\AppData\Blender\alibrary.dll C:\Users\Aaron\AppData\Blender\and_so_on.txt From this ordering my natural reaction is to partition the directory listings into groups... somehow... before doing the slow string comparisons. I'm really not sure. I would appreciate any ideas. Edit: It would be better if this tree were lazy loaded from the top down if possible.

  • Switching from LinqToXYZ to LinqToObjects

    - by spender
    In answering this question, it got me thinking... I often use this pattern: collectionofsomestuff //here it's LinqToEntities .Select(something=>new{something.Name,something.SomeGuid}) .ToArray() //From here on it's LinqToObjects .Select(s=>new SelectListItem() { Text = s.Name, Value = s.SomeGuid.ToString(), Selected = false }) Perhaps I'd split it over a couple of lines, but essentially, at the ToArray point, I'm effectively enumerating my query and storing the resulting sequence so that I can further process it with all the goodness of a full CLR to hand. As I have no interest in any kind of manipulation of the intermediate list, I use ToArray over ToList as there's less overhead. I do this all the time, but I wonder if there is a better pattern for this kind of problem?
