  • jQuery.load doesn't execute javascript with document.write

    - by Garfield
    I am trying to use jQuery.Load to load an ad call that has a document.write, and for some reason its not able to, or in firefox atleast, reloads the page with the entire ad. Here is the simplified version of the code. DynamicLoad.html <html> <head> <script src="http://www.prweekus.com/js/scripts.js?3729212881" type="text/javascript"></script> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>jQuery Load of Script</title> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); </script> <script type="text/javascript"> $(document).ready(function(){ $("#myButton").click(function() { $("#myDiv").load("source.html"); }); }); </script> </head> <body> <button id="myButton">Click Me</button> <div id="myDiv"></div> <div id="slideAdUnit"></div> </body> </html> Source.html <script language="javascript" type="text/javascript"> document.write('<script language="javascript" type="text/javascript"><\/script>'); </script> test Once you click the button in FF the browser just waits for something to load. Any thoughts ? Eventually I would be passing a src element in the document.write which points to our ad server. Thanks for your help.

  • WPF image cropping

    - by Califer
    I'm loading layers of images to make a single image. I'm currently stacking them all onto a canvas. I've got it set up so the user can specify the final dimensions of the single image, but even when I change the size of the canvas the images retain their original sizes. I tried to modify the image size as I was loading them in, but the sizes were NaN and the Actual Sizes were 0 so I couldn't change them there. I'm starting to think that canvas might not be the way to go. Any suggestions to how I could clip images to fit a specific size? canvas1.Children.Clear(); int totalImages = Window1.GetNumberOfImages(); if (drawBackground) canvas1.Background = new SolidColorBrush(Color.FromArgb(a,r,g,b)); else canvas1.Background = new SolidColorBrush(Color.FromArgb(0, 0, 0, 0)); for (int i = 0; i < totalImages; i++) { Image image = new Image(); image.Source = Window1.GetNextImage(i); canvas1.Children.Add(image); }

  • Graph drawing for the Web 2.0

    - by tokel
    Hi. There are a lot of chart drawing libraries out there, but what I am looking for is an interactive(!) graph (nodes and edges) drawing library. At best some kind of AJAX, but I am also open for other technologies (Java, Flash). However I would really prefer an AJAX implementation. Also only Open Source framework suggestions please (I already know about yFiles). The thing I have in mind is a bit like GWTUML. That is quite nice already, but misses an API for their graph drawing. It seems that it is an custom implementation for their product. Also some layout algorithms would be nice. Is there really no library around for that task? I wonder a bit as there are so many chart libraries available. Let me emphasize again (seems to be necessary cause of the first two comments): I am NOT looking for another chart library! Regards, Kai P.S. Things I know about already: JUNG (Java), Prefuse (Java), GINY (Java), yFiles (AJAX, but not Open Source). Just another graph library I found (Javascript, not sure if it is still maintained): Graph Gear

  • Python Locking Implementation (with threading module)

    - by Matty
    This is probably a rudimentary question, but I'm new to threaded programming in Python and am not entirely sure what the correct practice is. Should I be creating a single lock object (either globally or being passed around) and using that everywhere that I need to do locking? Or, should I be creating multiple lock instances in each of the classes where I will be employing them. Take these 2 rudimentary code samples, which direction is best to go? The main difference being that a single lock instance is used in both class A and B in the second, while multiple instances are used in the first. Sample 1 class A(): def __init__(self, theList): self.theList = theList self.lock = threading.Lock() def poll(self): while True: # do some stuff that eventually needs to work with theList self.lock.acquire() try: self.theList.append(something) finally: self.lock.release() class B(threading.Thread): def __init__(self,theList): self.theList = theList self.lock = threading.Lock() self.start() def run(self): while True: # do some stuff that eventually needs to work with theList self.lock.acquire() try: self.theList.remove(something) finally: self.lock.release() if __name__ == "__main__": aList = [] for x in range(10): B(aList) A(aList).poll() Sample 2 class A(): def __init__(self, theList,lock): self.theList = theList self.lock = lock def poll(self): while True: # do some stuff that eventually needs to work with theList self.lock.acquire() try: self.theList.append(something) finally: self.lock.release() class B(threading.Thread): def __init__(self,theList,lock): self.theList = theList self.lock = lock self.start() def run(self): while True: # do some stuff that eventually needs to work with theList self.lock.acquire() try: self.theList.remove(something) finally: self.lock.release() if __name__ == "__main__": lock = threading.Lock() aList = [] for x in range(10): B(aList,lock) A(aList,lock).poll()

  • Converting a Linq expression tree that relies on SqlMethods.Like() for use with the Entity Framework

    - by JohnnyO
    I recently switched from using Linq to Sql to the Entity Framework. One of the things that I've been really struggling with is getting a general purpose IQueryable extension method that was built for Linq to Sql to work with the Entity Framework. This extension method has a dependency on the Like() method of SqlMethods, which is Linq to Sql specific. What I really like about this extension method is that it allows me to dynamically construct a Sql Like statement on any object at runtime, by simply passing in a property name (as string) and a query clause (also as string). Such an extension method is very convenient for using grids like flexigrid or jqgrid. Here is the Linq to Sql version (taken from this tutorial: http://www.codeproject.com/KB/aspnet/MVCFlexigrid.aspx): public static IQueryable<T> Like<T>(this IQueryable<T> source, string propertyName, string keyword) { var type = typeof(T); var property = type.GetProperty(propertyName); var parameter = Expression.Parameter(type, "p"); var propertyAccess = Expression.MakeMemberAccess(parameter, property); var constant = Expression.Constant("%" + keyword + "%"); var like = typeof(SqlMethods).GetMethod("Like", new Type[] { typeof(string), typeof(string) }); MethodCallExpression methodExp = Expression.Call(null, like, propertyAccess, constant); Expression<Func<T, bool>> lambda = Expression.Lambda<Func<T, bool>>(methodExp, parameter); return source.Where(lambda); } With this extension method, I can simply do the following: someList.Like("FirstName", "mike"); or anotherList.Like("ProductName", "widget"); Is there an equivalent way to do this with Entity Framework? Thanks in advance.

  • Swing - how to mix JTextField and JTextAreas and have same visual appearance?

    - by I82Much
    I am using miglayout to create a form in which there are JTextFields (short input answers) as well as JTextAreas (Longer answers). The problem is twofold. The border placed around a Scrollpane wrapped text area does not match that of a Text Field. The width and placement of the textarea/textfield differ, causing them not to line up correctly. Source code: package test2; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.JTextField; import net.miginfocom.swing.MigLayout; public class Test extends JPanel { private static final int NUM_CHARACTERS_WIDTH = 20; private static final int NUM_ROWS = 5; public Test() { setLayout(new MigLayout( "wrap 2", // Align text labels on the so their right edge meets left edge of the text fields "[right][left]" )); add(new JLabel("Text field:")); add(new JTextField(NUM_CHARACTERS_WIDTH)); add(new JLabel("No scrollpane text area:")); add(new JTextArea(NUM_ROWS, NUM_CHARACTERS_WIDTH)); add(new JLabel("Scrollpane text area:")); add(new JScrollPane(new JTextArea(NUM_ROWS, NUM_CHARACTERS_WIDTH))); add(new JLabel("Text field:")); add(new JTextField(NUM_CHARACTERS_WIDTH)); } public static void main(String[] args) { JFrame frame = new JFrame(""); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new Test(); frame.add(panel); frame.pack(); frame.setVisible(true); } } What's the preferred way to mix and match jtextfield and jtextareas, while still maintaining visual harmony? I notice now that the text field has a blue highlight around it when focus is in it, as opposed to the text area... another source of visual discontinuity.

  • faster way to draw an image

    - by iHorse
    im trying to combine two images into a single image. unfortunately this has to be done very quickly in response to a user sliding a UISlider. i can combine the two images into a single image no problem. but the way I'm doing it is horribly slow. the sliders stick and jump rather frustratingly. i don't think i can throw the code into a background thread because i would run out of threads to quickly. i haven't actually tired that yet. below is my code. any ideas on how to speed it up would be helpful. UIGraphicsBeginImageContext(CGSizeMake(bodyImage.theImage.image.size.width * 1.2, bodyImage.theImage.image.size.height * 1.2)); [bodyImage.theImage.image drawInRect: CGRectMake(-2 + ((bodyImage.theImage.image.size.width * 1.2) - bodyImage.theImage.image.size.width)/2, kHeadAdjust, bodyImage.theImage.image.size.width * bodyImage.currentScale, bodyImage.theImage.image.size.height * bodyImage.currentScale)]; if(isCustHead) { [Head.theImage.image drawInRect: CGRectMake((bodyImage.theImage.image.size.width * 1.2 - headWidth)/2 - 11, 0, headWidth * 0.92, headWidth * (Head.theImage.image.size.height/Head.theImage.image.size.width) * 0.92)]; } else { [Head.theImage.image drawInRect: CGRectMake((bodyImage.theImage.image.size.width * 1.2 - (headWidth * defaultHeadAdjust))/2 - 10, 0, (headWidth * defaultHeadAdjust * 0.92), (headWidth * defaultHeadAdjust) * (Head.theImage.image.size.height/Head.theImage.image.size.width) * 0.92)]; } drawSurface.theImage.image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();

  • How to pull one commit at a time from a remote git repository?

    - by Norman Ramsey
    I'm trying to set up a darcs mirror of a git repository. I have something that works OK, but there's a significant problem: if I push a whole bunch of commits to the git repo, those commits get merged into a single darcs patchset. I really want to make sure each git commit gets set up as a single darcs patchset. I bet this is possible by doing some kind of git fetch followed by interrogation of the local copy of the remote branch, but my git fu is not up to the job. Here's the (ksh) code I'm using now, more or less: git pull -v # pulls all the commits from remote --- bad! # gets information about only the last commit pulled -- bad! author="$(git log HEAD^..HEAD --pretty=format:"%an <%ae>")" logfile=$(mktemp) git log HEAD^..HEAD --pretty=format:"%s%n%b%n" > $logfile # add all new files to darcs and record a patchset. this part is OK darcs add -q --umask=0002 -r . darcs record -a -A "$author" --logfile="$logfile" darcs push -a rm -f $logfile My idea is Try git fetch to get local copy of the remote branch (not sure exactly what arguments are needed) Somehow interrogate the local copy to get a hash for every commit since the last mirroring operation (I have no idea how to do this) Loop through all the hashes, pulling just that commit and recording the associated patchset (I'm pretty sure I know how to do this if I get my hands on the hash) I'd welcome either help fleshing out the scenario above or suggestions about something else I should try. Ideas?

  • RemoteRef.invoke implementation

    - by phill
    Just finished a basic implementation of RMI for a class project, and now I am interested in how it is actually done. Sun is kind enough to provide the source for the majority of the Java classes with the JDK, however an implementation of RemoteRef doesn't seem to be there. I have the source for the interface RemoteRef along with the ServerRef interface and one implementation, ProxyRef, which just calls invoke on another RemoteRef, but none of the classes that implement actual code, ActivatableRef or UnicastRef for example, are included. I mention ActivatableRef and UnicastRef because I believe these have proper implementations of invoke thanks to the wonder that is Eclipse and its class file editor showing that it is more then just a method declaration. Although I can tell that it is more then a declaration, I can't get much more out of it, building a string here, throw exception there, but nothing about the process that is taking place to send the remote method call. Would anyone here happen to know where I can get this code, or if its even available? If it is not available, would anyone happen to know what the message being sent to the server looks like? phill

  • Best practices for Java logging from multiple threads?

    - by Jason S
    I want to have a diagnostic log that is produced by several tasks managing data. These tasks may be in multiple threads. Each task needs to write an element (possibly with subelements) to the log; get in and get out quickly. If this were a single-task situation I'd use XMLStreamWriter as it seems like the best match for simplicity/functionality without having to hold a ballooning XML document in memory. But it's not a single-task situation, and I'm not sure how to best make sure this is "threadsafe", where "threadsafe" in this application means that each log element should be written to the log correctly and serially (one after the other and not interleaved in any way). Any suggestions? I have a vague intuition that the way to go is to use a queue of log elements (with each one able to be produced quickly: my application is busy doing real work that's performance-sensitive), and have a separate thread which handles the log elements and sends them to a file so the logging doesn't interrupt the producers. The logging doesn't necessarily have to be XML, but I do want it to be structured and machine-readable. edit: I put "threadsafe" in quotes. Log4j seems to be the obvious choice (new to me but old to the community), why reinvent the wheel...

  • Using LINQ to SQL and chained Replace

    - by White Dragon
    I have a need to replace multiple strings with others in a query from p in dx.Table where p.Field.Replace("A", "a").Replace("B", "b").ToLower() = SomeVar select p Which provides a nice single SQL statement with the relevant REPLACE() sql commands. All good :) I need to do this in a few queries around the application... So i'm looking for some help in this regard; that will work as above as a single SQL hit/command on the server It seems from looking around i can't use RegEx as there is no SQL eq Being a LINQ newbie is there a nice way for me to do this? eg is it possible to get it as a IQueryable "var result" say and pass that to a function to add needed .Replace()'s and pass back? Can i get a quick example of how if so? EDIT: This seems to work! does it look like it would be a problem? var data = from p in dx.Videos select p; data = AddReplacements(data, checkMediaItem); theitem = data.FirstOrDefault(); ... public IQueryable<Video> AddReplacements(IQueryable<Video> DataSet, string checkMediaItem) { return DataSet.Where(p => p.Title.Replace(" ", "-").Replace("&", "-").Replace("?", "-") == checkMediaItem); }

  • Making a 64 bit shared library that dynamically links to a 32 bit library on Mac OS X Snow Leopard

    - by carneades
    Update: After some more reading I see that this problem is totally general, you can't mix architectures in the same process, so 64 bit Java cannot dlopen() a 32 bit library like FMOD. Is there any possible workaround for this, keeping in mind I'm writing my own C interface to the FMOD library? I need to make a 64-bit dylib on Max OS X because Java Native Access only likes 64-bit libraries on 64-bit machines. The problem is, my C source code dynamically includes FMOD which on Mac only provides 32-bit dylibs. When I try to compile without the -m32 option (since I must output a 64-bit dylib) I get the following error: gcc -dynamiclib -std=c99 -pedantic -Wall -O3 -fPIC -pthread -o ../bin/libpenntotalrecall_fmod.dylib ../../src/libpenntotalrecall_fmod.c -lfmodex -L../../lib/osx/ ld: warning: in /usr/lib/libfmodex.dylib, missing required architecture x86_64 in file Undefined symbols: "_FMOD_System_CreateSound", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_Channel_GetPosition", referenced from: _streamPosition in ccJnlwrd.o "_FMOD_System_Create", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_System_PlaySound", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_Sound_Release", referenced from: _stopPlayback in ccJnlwrd.o "_FMOD_Channel_IsPlaying", referenced from: _playbackInProgress in ccJnlwrd.o "_FMOD_System_Update", referenced from: _streamPosition in ccJnlwrd.o _startPlayback in ccJnlwrd.o "_FMOD_Channel_SetPaused", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_System_Release", referenced from: _stopPlayback in ccJnlwrd.o "_FMOD_System_Init", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_Channel_SetVolume", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_System_Close", referenced from: _stopPlayback in ccJnlwrd.o "_FMOD_Channel_SetCallback", referenced from: _startPlayback in ccJnlwrd.o ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [all] Error 1 Shouldn't it be possible to get a 64 bit dylib from my source code that dynamically includes 32 bit libraries?!

  • Grouping Collection seperating numeric 5 from String "5"

    - by invertedSpear
    BackGround: I have an advanced data grid. The data provider for this ADG is an ArrayCollection. There is a grouping collection on an ID field of this AC. Example of a couple items within this AC the AC var name is "arcTemplates": (mx.collections::ArrayCollection)#0 filterFunction = (null) length = 69 list = (mx.collections::ArrayList)#1 length = 69 source = (Array)#2 [0] (Object)#3 abbreviation = "sore-throat" insertDate = "11/16/2009" name = "sore throat" templateID = 234 templateType = "New Problem" templateTypeID = 1 [32] (Object)#35 abbreviation = 123 insertDate = "03/08/2010" name = 123 templateID = 297 templateType = "New Problem" templateTypeID = 1 [55] (Object)#58 abbreviation = 1234 insertDate = "11/16/2009" name = 1234 templateID = 227 templateType = "Exam" templateTypeID = 5 [56] (Object)#59 abbreviation = "breast only" insertDate = "03/15/2005" name = "breast exam" templateID = 195 templateType = "Exam" templateTypeID = 5 Example of Flex code leading to the Grouping: <mx:AdvancedDataGrid displayItemsExpanded="true" id="gridTemplates"> <mx:dataProvider> <mx:GroupingCollection id="gc" source="{arcTemplates}"> <mx:Grouping > <mx:GroupingField name="templateTypeID" compareFunction="gcSort"> GC sort function: public function gcSort(a:Object, b:Object):int{ return ObjectUtil.stringCompare(String(a.templateTypeID + a.name).toLowerCase(), String(b.templateTypeID + b.name).toLowerCase()); } Problem: In my AC example there are a few items, items 0, 32 and 56 properly sort and group to their templateTypeID, but item 55 does something weird. It seems to sort/group on the numeric 5 instead of the string "5". Gets stranger. If I change the name property to contain text (so 1234x) it then correctly sorts/groups to the string "5" Question: What is going on here and how do I fix it?

  • Why would the VB.NET compiler think an interface isn't implemented when it is?

    - by Dan Tao
    I have this happen sometimes, particularly with the INotifyPropertyChanged interface in my experience but I have no idea if the problem is limited to that single interface (which would seem bizarre) or not. Let's say I have some code set up like this. There's an interface with a single event. A class implements that interface. It includes the event. Public Interface INotifyPropertyChanged Event PropertyChanged As PropertyChangedEventHandler End Interface Public Class Person Implements INotifyPropertyChanged Public Event PropertyChanged _ (ByVal sender As Object, ByVal e As PropertyChangedEventArgs) _ Implements INotifyPropertyChanged.PropertyChanged ' more code below ' End Class Every now and then, when I build my project, the compiler will suddenly start acting like the above code is broken. It will report that the Person class does not implement INotifyPropertyChanged because it doesn't have a PropertyChanged event; or it will say the PropertyChanged event can't implement INotifyPropertyChanged.PropertyChanged because their signatures don't match. This is weird enough as it is, but here's the weirdest part: if I just cut out the line starting with Event PropertyChanged and then paste it back in, the error goes away. The project builds. Does anybody have any clue what could be going on here?

I am building it in a similar fashion to facebook's system, so messages are grouped into threads, etc. My related models are: MsgThread - main container of a thread Message - each message/reply in thread Recipience - ties to user to define which users should subscribe to this thread Read - determines whether or not a user has read a specific message My relationships look like class User < ActiveRecord::Base #stuff... has_many :msg_threads, :foreign_key => 'originator_id' #threads the user has started has_many :recipiences has_many :subscribed_threads, :through => :recipiences, :source => :msg_thread #threads the user is subscribed to end class MsgThread < ActiveRecord::Base has_many :messages has_many :recipiences belongs_to :originator, :class_name => "User", :foreign_key => "originator_id" end class Recipience < ActiveRecord::Base belongs_to :user belongs_to :msg_thread end class Message < ActiveRecord::Base belongs_to :msg_thread belongs_to :author, :class_name => "User", :foreign_key => "author_id" end class Read < ActiveRecord::Base belongs_to :user belongs_to :message end I'd like to create a new selector in the user sort of like: has_many :updated_threads, :through => :recipiencies, :source => :msg_thread, :conditions => {THREAD CONTAINS MESSAGES WHICH ARE UNREAD (have no 'read' models tying a user to a message)} I was thinking of either writing a long condition with multiple joins, or possibly writing giving the model an updated_threads method to return this, but I'd like to see if there is an easier way first. Any ideas? Also, if there is something fundamentally wrong with my structure for this functionality let me know! Thanks!!

  • WPF Spellcheck Engine takes up too much memory.

    - by Matt H.
    Each datatemplate in my WPF ItemsControl contains FIVE custom bindable richtextbox controls. It is a data-driven app that for authoring multiple-choice questions -- The question and four answer choices must all support: 1) Spell check 2) Rich formatting (otherwise I'd use regular textboxes) The spell check object in .NET 4 has a Friend constructor that takes a single argument of owner As TextBoxBase This means every richtextbox in the ItemsControl has 5 Spellcheck objects! This is the problem -- every spell check engine is consuming about 500k memory. So after you favor in the spellcheck, bindings, additional controls in the DataTemplate, etc.. a single multi choice question consumes more than 3MB memory. Users with 100--200 questions will quickly see the App raise it's memory consumption to 500+ MB. Management is definitely not OK with this. Is there a way to minimimze this problem? The best suggestion I've heard is to enable/disable spellcheck if the richtextbox is in the ItemsControl's scrollviewer: I haven't gotten an answer to how to go about it: (http://stackoverflow.com/questions/2869012/possible-to-implement-an-isviewportvisible-dependencyproperty-for-an-item-in-an-i) Any good ideas?

  • Problem Displaying XML in Grid View-newbie

    - by Dean
    I am trying to do something in VisualWebDev 2008 Express that I thought would be simple, but it is not working. I want to display data from an XML file so I added the XMLDataSource to my page, pointed it to the XML file, and then added the GridView and connected it to the datasource. I am getting the following error: GridView - GridView1There was an error rendering the control. The data source for GridView with id 'GridView1' did not have any properties or attributes from which to generate columns. Ensure that your data source has content. Could someone please tell me what I might be doing wrong, TIA Dean A smippet from my XML is as follows: 6019 - Renaissance MS - New School Renaissance MS 7155 Hall Road Fairburn, GA 30213 NS-6019200-LA-01 New School Close-out NS-6019200 0.000000000000000e+000 The construction of the new Renaissance MS will be at the intersection of Jones/Hall Road, in the districts 7th & 9F and Land Lots 117, 143 & 146 of Fulton County, GA. The work includes the construction of the 180,500 square foot building that will house 34 standard classrooms, 12 standard science labs, 20 special purpose classrooms, cafeteria and litchen, gymnasium, media center and administrative offices. The site will also have multi-purpose playfields with track, softball field, tennis courts and basketball/volleyball court.

  • Need Advice on designing ATL inproc Server (dll) that serves as both a soure and a sink of events.

    - by Andrew
    Hi, I need to design an ATL inproc server that besides exposing methods and properties, also can fire events (source) and serve as a sink for a third party COM control that fires events. I would assume that this is a fairly common requirement. I can also foresee several "gotchas" that I would like to read up on before commencing the design. My questions/concerns are: Can someone point me to an example? Which threading model to use? Should I have a seperate COM object for the sink? Should I, and how do I, protect certain memory. For example, my server will receive data from the third party control. It will save this, and in some cases, fire an event to interested clients. The interested clients will request the data through a standard method or property. I did try to research this myself. I can find many examples of COM servers that are soures, and some that are sinks, but never both. The only post I did find was this: http://www.generation-nt.com/us/atl-control-an-event-source-sink-help-9098542.html Which strongly advocates putting the sink on a seperate COM object. Any leads, tutorials or ideas would be much appreciated. Thanks, Andrew

  • C# LINQ to XML nissing space character.

    - by Fossaw
    I write an XML file "by hand", (i.e. not with LINQ to XML), which sometimes includes an open/close tag containing a single space character. Upon viewing the resulting file, all appears correct, example below... <Item> <ItemNumber>3</ItemNumber> <English> </English> <Translation>Ignore this one. Do not remove.</Translation> </Item> ... the reasons for doing this are various and irrelevent, it is done. Later, I use a C# program with LINQ to XML to read the file back and extract the record... XElement X_EnglishE = null; // This is CRAZY foreach (XElement i in Records) { X_EnglishE = i.Element("English"); // There is only one damned record! } string X_English = X_EnglishE.ToString(); ... and test to make sure it is unchanged from the database record. I detect a change, when processing Items where the field had the single space character... +E+ Text[3] English source has been altered: Was: >>> <<< Now: >>><<< ... the and <<< parts I added to see what was happening, (hard to see space characters). I have fiddled around with this but can't see why this is so. It is not absolutely critical, as the field is not used, (yet), but I cannot trust C# or LINQ or whatever is doing this, if I do not understand why it is so. So what is doing that and why?

  • Visual Studio 2008 "Save File As" Dialog Intermittent Issue

    - by Jerad Rose
    Me and a few of my coworkers are experiencing an odd issue in Visual Studio 2008 and Windows 7 (64-bit). We use VSS6 for our source control (unfortunately). We have an issue where we will make a change to a checked-out file, resulting in the file getting checked out as expected. But when we go to build the project, or try to save the file, it will often (but not always) prompt us with the "Save File As" dialog, as if VS thinks the file is checked-in (and thus has the read-only flag set). However, all we have to do is cancel out of the dialog and save or build again, and it will always work the second time, without prompting the save as dialog. Or, we can go through with the save as, leaving the name the same, and it will work. It's as if the source control status in VS2008 hasn't caught up w/ VSS (even though we VS2008 was the app that checked the file out). This is similar to the discussion on this thread, but it's not an issue of permissions or running as administrator, 1) because it resolves itself on second attempt, and 2) we're already running VS as administrator. Thanks in advance. Jerad

  • Windows 7 theme for WPF?

    - by DanM
    Is there any way to make a WPF app look like it's running on Windows 7 even if it's running on XP? I'm looking for some kind of theme I can just paste in. I'm aware of the themes project on Codeplex (http://www.codeplex.com/wpfthemes), but it lacks support for DataGrid, which is something I critically need. I was thinking maybe the Windows 7 theme would just be an easy port, or exists in some file somewhere already. Any information you have (even if it's bad news) would be much appreciated. Update Using @Lars Truijens idea, I was able to get the Windows 7 look for the major controls, but unfortunately it did not work for the WPF Toolkit DataGrid control, which I need. DataGrid looks like this with Aero theme DataGrid should look like this So, I'm still looking for a solution to this problem if anyone has any ideas. Maybe someone has built an extension to the Aero theme that covers the WPF toolkit controls? Again, any information you have is much appreciated. Update 2 - Problem solved! To get the Aero theme to work with WPF Toolkit controls, you just need to add a second Aero dictionary, so your App.xaml should now look like this. <Application.Resources> ... <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml" /> <ResourceDictionary Source="pack://application:,,,/WPFToolkit;component/Themes/Aero.NormalColor.xaml" /> ... </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> Also, I would recommend turning the gridlines off in your DataGrid controls (because they look horrible): <DataGrid GridLinesVisibility="None" ...>

  • Libraries for developing NCPDP SCRIPT based systems (a standard for e-prescribing)

    - by Kaveh Shahbazian
    What are (based on experiences) best (commercial or open source) libraries for developing NCPDP-based systems? Background: NCPDP (National Council for Prescription Drug Programs) is a not-for-profit, ANSI-accredited, standards development organization. One of it's standards is the SCRIPT Standard for Electronic Prescribing, which allows PHARMACY, PRESCRIBER (i.e. Physician) and PAYERS (patient or more often insurer) communicate. So the SCRIPT standard is about data transmission. Problem: One step in implementing such systems is to develop models for data based on SCRIPT standard. These models should have utilities for serializing/deserializing to/from SCRIPT binary format and SCRIPT XML format (there are two distinct formats here; both must be supported). Here rises the problem (for me at least). To develop this subsystem for handling the model, implementing serializing and deserializing facilities and keep it uptodate with the SCRIPT standard specifications is a lot of work; it needs it's own team and team management issues (to support a standard implementation). So I am looking for a solution to this problem; to keep standard implementation out of the way and focusing on main problems. Thanks to all (Thankyou Freiheit for your hints!) Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?
