  • WPF - How do I style a row based on a binding property value?

    - by Nick
    Hey! So I am trying to bind a collection of objects (IList<) to a WPF datagrid. I would like to make the row background a different color if the 'artist' property is null or empty. I am checking the value stored at the property on the LoadingRow datagrid event. Currently my implementation seems to style all of the rows with an empty or null 'artist' property correctly. The problem is that is also styles the rows where the property is not null or empty in some cases. So some rows are given the red background even though the rows 'artist' property is not null. Can anyone tell me why this could be?? Here is the LoadingRow event: private void trackGrid_LoadingRow(object sender, DataGridRowEventArgs e) { Track t = e.Row.DataContext as Track; if (String.IsNullOrEmpty(t.Artist)) { e.Row.Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(255, 255, 125, 125)); } }

  • How do you use stl's functions like for_each?

    - by thomas-gies
    I started using stl containers because they came in very handy when I needed functionality of a list, set and map and had nothing else available in my programming environment. I did not care much about the ideas behind it. STL documentations were only interesting up to the point where it came to functions, etc. Then I skipped reading and just used the containers. But yesterday, still being relaxed from my holidays, I just gave it a try and wanted to go a bit more the stl way. So I used the transform function (can I have a little bit of applause for me, thank you). From an academic point of view it really looked interesting and it worked. But the thing that boroughs me is that if you intensify the use of those functions, you need 10ks of helper classes for mostly everything you want to do in your code. The hole logic of the program is sliced in tiny pieces. This slicing is not the result of god coding habits. It's just a technical need. Something, that makes my life probably harder not easier. And I learned the hard way, that you should always choose the simplest approach that solves the problem at hand. And I can't see what, for example, the for_each function is doing for me that justifies the use of a helper class over several simple lines of code that sit inside a normal loop so that everybody can see what is going on. I would like to know, what you are thinking about my concerns? Did you see it like I do when you started working this way and have changed your mind when you got used to it? Are there benefits that I overlooked? Or do you just ignore this stuff as I did (and will go an doing it, probably). Thanks. PS: I know that there is a real for_each loop in boost. But I ignore it here since it is just a convenient way for my usual loops with iterators I guess.

  • jQuery variables and scope

    - by Peuge
    I am writing a jQuery plugin and am running into a few problems with regard to variables. For example I have the following skeleton structure for my plugin, which is going to act on a textbox. In my init function I want to set a variable and bind a keypress event to my textbox. That keypress event needs to call another function, in which I need the variable. Is this possible? (function($){ var methods = { init : function(options){ return this.each(function(){ var $this = $(this); var someVar = 'somevar'; $this.keypress(function(event){ //I want to call my customFunction }); }); }, customFunction : function(){ //I am wanting to access 'someVar' here }; $.fn.mynamespace = function(method){ //handle which method to call here }; })(jQuery); Many thanks in advance.

  • Style Data in a gridview which dynamically generates the columns

    - by Coesy
    I have built a dynamic gridview using the following code grdVariants.Columns.Clear(); int i = 0; foreach (DataColumn column in options.Columns) { grdVariants.Columns.Add(new GridViewColumn { Header = column.ColumnName, DisplayMemberBinding = new Binding(string.Format("[{0}]", i++)) }); } This will dynamically generate my columns at runtime, I then bind the data using lstVariantsGrid.DataContext = options; lstVariantsGrid.Items.Refresh(); This all works great and shows the data in the correct columns etc, the only issue i have is that I can't style the rows like I would in xaml as it is all an unknown quantity until runtime. Can anyone offer some advice on how I might go about doing this? One of the biggest problems I have is that one of the columns needs to display the image rather than just the path which it currently shows, as well as fiddling with fonts and colors etc. Thanks for your time.

  • Auto enter pass phrase in case of Python ssl Client/Server

    - by rauch
    I need to create Client/Server application to send files from clients to Server. I use simple ssl sockets for that and authenticate with certificates. ms = socket.socket(socket.AF_INET, socket.SOCK_STREAM) ssl_sock = ssl.wrap_socket(ms, keyfile=".../newCA/my_client.key", certfile=".../newCA/my_client.crt", server_side=0, cert_reqs=ssl.CERT_REQUIRED, ca_certs=".../newCA/CA/my-ca.crt" ) ssl_sock.connect((HOST, MPORT)) And Server side: msock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.ssl_sock = ssl.wrap_socket(msock, keyfile=".../newCA/my_server.key", certfile=".../newCA/my_server.crt", server_side=1, cert_reqs=ssl.CERT_REQUIRED, ca_certs=".../newCA/CA/my-ca.crt" ) self.ssl_sock.bind(('', self.PORT)) self.ssl_sock.listen(self.QUEUE_MAX) The problem is the following: when client tries to connect to Server, it requires Enter the pass phrase for private key for Both: for Server-side and Client-side. In Java we need to set System Property: javax.net.ssl.keyStorePassword="" and it has to be used automatically, But how is it been used in Python? I can't enter pass phrase all time the client connects.

  • Using Jquery, call function on selection just once

    - by maxp
    Say i have a selection of textboxes like this; var arrayoftextboxes = $('.textbox1, .textbox2, .textbox3'); Is there a way I can call a function on each one in a simpler way than this? It only needs to be called once. arrayoftextboxes.each(function(i){foo(arrayoftextboxes[i]);}); I tried arrayoftextboxes.load(function(){foo(this)}); and arrayoftextboxes.bind(function(){foo(this)}); but the functions dont seem to be called.

  • Why does this binding doesn't work through XAML but does by code ?

    - by user361899
    I am trying to bind to a static property on a static class, this property contains settings that are deserialized from a file. It never works with the following XAML : <Window.Resources> <ObjectDataProvider x:Key="wrapper" ObjectType="{x:Type Application:Wrapper}"/> </Window.Resources> <ScrollViewer x:Name="scrollViewer" ScrollViewer.VerticalScrollBarVisibility="Auto"DataContext="{Binding Source={StaticResource wrapper}, UpdateSourceTrigger=PropertyChanged}"> <ComboBox x:Name="comboboxThemes" SelectedIndex="0" SelectionChanged="ComboBoxThemesSelectionChanged" Grid.Column="1" Grid.Row="8" Margin="4,3" ItemsSource="{Binding Settings.Themes, Mode=OneWay}" SelectedValue="{Binding Settings.LastTheme, Mode=TwoWay}" /> It does work by code however : comboboxThemes.ItemsSource = Settings.Themes; Any idea ? Thank you :-)

  • MAC : How to check if the file is still being copied in cpp?

    - by Peda Pola
    In my current project, we had a requirement to check if the file is still copying. We have already developed a library which will give us OS notification like file_added , file_removed , file_modified, file_renamed on a particular folder along with the corresponding file path. The problem here is that, lets say if you add 1 GB file, it is giving multiple notification such as file_added , file_modified, file_modified as the file is being copied. Now i decided to surpass these notifications by checking if the file is copying or not. Based on that i will ignore events. I have written below code which tells if the file is being copied or not which takes file path as input parameter. Details:- In Mac, while file is being copied the creation date is set as some date less than 1970. Once it is copied the date is set to current date. Am using this technique. Based on this am deciding that file is being copied. Problem:- when we copy file in the terminal it is failing. Please advice me any approach. bool isBeingCopied(const boost::filesystem::path &filePath) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; bool isBeingCopied = false; if([[[[NSFileManager defaultManager] attributesOfItemAtPath:[NSString stringWithUTF8String:filePath.string().c_str()] error:nil] fileCreationDate] timeIntervalSince1970] < 0) { isBeingCopied = true; } [pool release]; return isBeingCopied; }

  • How to set up a has-many relationship in Cocoa?

    - by SphereCat1
    I'm building a (very) simple FTP app in Cocoa, and I need to store information on the different types of servers that are supported. So, I've created a ServerType class, which stores all of the relevant information about a single type of server. I then have a ServerTypes class which is designed to manage all of the ServerType classes that are created. My question is how to set up the relationship between the two objects. Is there a preferred method to do so? Also, since Objective-C doesn't support non-instance classes, where should I create an instance of ServerTypes that will have to be used throughout the entire program? Or is there a better way to do that? I need it to be KVC compliant so That I can bind one of the ServerType properties to an NSPopupBox. Sorry about the large volume of questions, I'm fairly new to Cocoa and Objective-C. If you need to see code, just ask and I'll be happy to add some. :) SphereCat1

  • WPF Binding not updating when binded object is updated

    - by Chris Klepeis
    I'm trying to bind to a custom control like so: <my:GanttChartTaskListView Name="ganttChartTaskListView1" ItemsSource="{Binding Source={x:Static local:TaskCollection.taskList}}" /> In my WPF Window constructor I add add an item to my taskList, when it loads I can see that item in my custom control, however, when I subsequently add items it does not update. I tried setting Mode=TwoWay, however, then it says the "Path" is required and I'm not familiar with binding like that (this is new to me). Here is my TaskCollection class: namespace ProjectManager { public static class TaskCollection { private static List<TaskItem> _taskList = new List<TaskItem>(); public static List<TaskItem> taskList { get {return _taskList; } set { _taskList = value; } } } } Any ideas? Is there a better / easier way to do this?

  • Is it okay if my ViewModel 'creates' bindable user controls for my View?

    - by j0rd4n
    I have an entry-point View with a tab control. Each tab is going to have a user control embedded within it. Each embedded view inherits from the same base class and will need to be updated as a key field on the entry-point view is updated. I'm thinking the easiest way to design this page is to have the entry-point ViewModel create and expose a collection of the tabbed views so the entry-point View can just bind to the user control elements using a DataTemplate on the tab control. Is it okay for a ViewModel to instantiate and provide UI elements for its View?

  • ASP.Net Reportviewer in folder not working

    - by Bruce
    We can run the ReportViewer in a ASP.Net Web App project that is off the root OK so localhost/test/report.aspx works. It's running as a Client Report. But if we move the application up another level the report stops working so localhost/testfolder/test/test.aspx. When the report fails it has no data to display and none of the images are loading. Info: We are bind the report in code and sort out the Report.LocalReport.ReportPath to the correct path. Can't help thinking there is a setting wrong, but stumped at the moment!

    - by baDa
    Hello everyone! I was a flash developer for 3 years, and in the last 5 months, i begin the iphone development, i do 2 applications with interface builder for clients, and now i really want to do a little game, is quite simple, one match 3! I made the engine in interface builder, and seens good to me! But after i read some posts, i really want to try it in the cocos2D! So, in 2 days i rewrite all my first engine for cocos2D, very annoying upsidedown coordinates but ok, i really do! But the performance side by side with interface builder version is really scare! Many Many slow downs at the cocos2d side! And the animation seens bugged to me! I really scare! I really don't know what is the best choice for a simple game. And i want some opinions: Using cocos2d when need some physics? When we have many objects at screen? What is the performance boost i have with cocos2D? I have how to share this 2 applications with you guys?! Without your UID?!

  • jQuery DataLink - Does DataLink solve my use case?

    - by AnApprentice
    Hello, I recently heard of the jQuery datalink plugin and wondered if I should be using if for the following: I have a an inbox in my app that consists of the following: Inbox (index) - List of Items (list of mails) Inbox (show) Item Viewer (1 mail) Inbox Unread Counter The challenge I'm having now is a user can mark a mail as read/unread in either view which makes keeping the counter accurate challenging. Can datalink help with this? If so how? Also, I read that datalink requires forms is that true? Or can I bind the links to anything like 0 and anytime a mailitem changes from read to unread it would automatically update? Thanks

  • [Linux] domain socket "sendto" encounter "errno 111, connection refused"

    - by z.cHris
    I am using domain socket to get values from another process, like A to get a value from B, It works well for months. But recently, A is failed during "sendto" message to B with "errno 111, connection refused" occasionally. I checked the B domain socket bind file, it is exists. I also do some tests in another machine, also works well. So, does anyone encounter this problem before? Can anyone have some clues what might be probably wrong in this scenario? Thanks very much.

  • Why can't I expose an interface in a .NET asmx web service?

    - by mcliedtk
    I have a .NET web service (using asmx...have not upgraded to WCF yet) that exposes the following: public class WidgetVersion1 : IWidget {} public class WidgetVersion2 : IWidget {} When I attempt to bind to the web service, I get the following serialization error: Cannot serialize member WidgetVersion1 of type IWidget because it is an interface. I have tried adding various attributes to the IWidget interface (XmlIgnore, SoapIgnore, NonSerialized), but they are not valid on an interface. Does anyone know why I am unable to expose the interface? I assume WSDL does not support interfaces, but couldn't .NET get around this by simply not serializing the interface? Are there any ways around this apart from removing the IWidget interface from the WidgetVersion1 and WidgetVersion2 class definitions?

  • C++: Efficiently adding integers to strings

    - by Shinka
    I know how to add integers to strings, but I'm not sure I'm doing it in an efficient matters. I have a class where I often have to return a string plus an integer (a different integer each time), in Java I would do something like public class MyClass { final static String S = "MYSTRING"; private int id = 0; public String getString() { return S + (id++); } } But in C++ I have to do; class MyClass { private: std::string S; // For some reason I can't do const std::string S = "MYSTRING"; int id; public: MyClass() { S = "MYSTRING"; id = 0; } std::string getString() { std::ostringstream oss; oss << S << id++; return oss.str(); } } An additional constraint: I don't want (in fact, in can't) use Boost or any other librairies, I'll have to work with the standard library. So the thing is; the code works, but in C++ I have to create a bunch of ostringstream objects, so it seems inefficient. To be fair, perhaps Java do the same and I just don't notice it, I say it's inefficient mostly because I know very little about strings. Is there a more efficient way to do this ?

  • Jquery disable link for 5 seconds

    - by John
    I have this code: $('#page-refresh').click( function() { $.ajax({ url: "/page1.php", cache: false, dataType: "html", success: function(data) { $('#pagelist').html(data); } }); return false; }); In this code is it possible that on the ajax success function it disables the #page-refresh click for 5 seconds then re-enable it? Basically if a person clicks the button and this action happens I dont want them to click and run this action again for another 5 seconds. I looked at delay() to unbind the click for this then bind it again but once it unbinded it never allowed me to click the button anymore.

  • Click Function on jQuery plugin only allows for single click

    - by user1427307
    I've created this simple plugin to add multiple animations on click but the problem is that once the object is clicked it can not repeat the animation by clicking again, i can't figure out why the added class is not removing itself after the click function is complete to allow it to be clicked again and repeat.. any suggestions? (function($) { $.fn.vivify = function(options) { var defaults = { animation: 'bounce', }; var options = $.extend(defaults, options); return this.each(function() { var o = options; var obj = $(this); var animation = o.animation; obj.bind("click", function() { obj.addClass(o.animation); obj.addClass('vivify'); }, function() { obj.removeClass(o.animation); }); }) } })(jQuery);

I have a property called EntryType which is an int. There are 2 available numbers 1 or 2 Lets say I had 3 items that my query is working with 2 of them had the EntryType = 1 and the 3rd had EntryType2. The first records had a ItemAmount of 55.00 and the 3rd had a ItemAmount of 50.00 How can I group using something simlar to above but minus the ItemAmount of 50.00 from the grouped amount to return 60.00?
