  • Silverlight DataGrid refresh problem

    - by Krimson
    Hi, I have encountered a problem when I refresh the observable collection behind my Silverlight DataGrid (the DataGrid binds to a PagedCollectionView with an ObservableCollection as source). When I clear the observable collection and add the new items to the collection the DataGrid repositions to the top. I want the DataGrid to keep the scroll position. This seems to somewhat happen if I remove the items in the collection one-by-one with the RemoveAt mehtod and the add the new items one-by-one. But why is there this difference between removing all the items at once with the Clear method and removing the items one-by-one with the RemoveAt method? Best Regards, Jesper

  • MacPorts, how to run "post-destroot" script

    - by Potatoswatter
    I'm trying to install MacPorts gdb; it seems to be poorly supported… Running "port install" installs it to /opt/local/libexec/gnubin/gdb, but the intent doesn't seem to be to add that to $PATH. The portfile doesn't define any parameters for port select which is typically used to set a MacPorts installation to handle default Unix commands. But it does include these lines: foreach binary [glob -tails -directory ${destroot}${prefix}/bin g*] { ln -s ${prefix}/bin/${binary} ${destroot}${prefix}/libexec/gnubin/[string range $binary 1 end] } This is buried under an action labeled post-destroot. destroot is a MacPorts command but post-destroot is not. The script is apparently not run by port install or port activate, or if it's failing it's doing so silently. Is there a better approach than creating the links manually?

  • How to improve the builder pattern?

    - by tangens
    Motivation Recently I searched for a way to initialize a complex object without passing a lot of parameter to the constructor. I tried it with the builder pattern, but I don't like the fact, that I'm not able to check at compile time if I really set all needed values. Traditional builder pattern When I use the builder pattern to create my Complex object, the creation is more "typesafe", because it's easier to see what an argument is used for: new ComplexBuilder() .setFirst( "first" ) .setSecond( "second" ) .setThird( "third" ) ... .build(); But now I have the problem, that I can easily miss an important parameter. I can check for it inside the build() method, but that is only at runtime. At compile time there is nothing that warns me, if I missed something. Enhanced builder pattern Now my idea was to create a builder, that "reminds" me if I missed a needed parameter. My first try looks like this: public class Complex { private String m_first; private String m_second; private String m_third; private Complex() {} public static class ComplexBuilder { private Complex m_complex; public ComplexBuilder() { m_complex = new Complex(); } public Builder2 setFirst( String first ) { m_complex.m_first = first; return new Builder2(); } public class Builder2 { private Builder2() {} Builder3 setSecond( String second ) { m_complex.m_second = second; return new Builder3(); } } public class Builder3 { private Builder3() {} Builder4 setThird( String third ) { m_complex.m_third = third; return new Builder4(); } } public class Builder4 { private Builder4() {} Complex build() { return m_complex; } } } } As you can see, each setter of the builder class returns a different internal builder class. Each internal builder class provides exactly one setter method and the last one provides only a build() method. Now the construction of an object again looks like this: new ComplexBuilder() .setFirst( "first" ) .setSecond( "second" ) .setThird( "third" ) .build(); ...but there is no way to forget a needed parameter. The compiler wouldn't accept it. Optional parameters If I had optional parameters, I would use the last internal builder class Builder4 to set them like a "traditional" builder does, returning itself. Questions Is this a well known pattern? Does it have a special name? Do you see any pitfalls? Do you have any ideas to improve the implementation - in the sense of fewer lines of code?

  • How can I remove UNC password from a file

    - by freddoo
    Hi we have an mp4 file on our web server in a virtual directory When we try to access the file we get prompted for a username/password. When I tried to change the path of the virtual directory I got the message 'The following child nodes also define the value of the "UNCPassword" property, which overrides the value you have just set ...' which included the mp4 file that we try to access. How can I remove the UNC Password securing the file? The file is not on a shared drive its on the same drive as the web site root. The funny thing is the path of the virtual directory is not a UNC path it's a full path on the same server d:.....

  • The Boss Answer: What is a relational database?

    - by kce
    I'm mostly a system administrator and I don't directly work with databases other than installing them, setting up accounts, granting privileges, and so on. I realized that if The Boss walked up to me and asked, "What is a relational database?" I probably couldn't give a satisfactory answer... I'd maybe mumble something about data being stored and organized by categories which you can query with a special programing language (i.e., SQL). So could someone give a good "Boss Answer" for what a relational database is? And maybe how its different than just storing data on a file server? Bonus points for clever but accessible analogies and explaining tables, columns, records and fields. I'd define a "Boss Answer" as a quick one (maybe two) paragraph explanation for non-technical folks... mostly your Boss, on those rare occasions they actually ask you what it is you do all day.

  • Dynamically generate PDF and email it using django

    - by Shane
    I have a django app that dynamically generates a PDF (using reportlab + pypdf) from user input on an HTML form, and returns the HTTP response with an application/pdf MIMEType. I want to have the option between doing the above, or emailing the generated pdf, but I cannot figure out how to use the EmailMessage class's attach(filename=None, content=None, mimetype=None) method. The documentation doesn't give much of a description of what kind of object content is supposed to be. I've tried a file object and the above application/pdf HTTP response. I currently have a workaround where my view saves a pdf to disk, and then I attach the resulting file to an outgoing email using the attach_file() method. This seems wrong to me, and I'm pretty sure there is a better way.

  • UIBarButtonItem: target-action not working?

    - by Jacob Relkin
    Hey fellas, I've got a custom view inside of a UIBarButtonItem, set by calling -initWithCustomView. OK, so the view renders fine, but when I tap it, it doesn't call the method that I set as the UIBarButtonItem's action property. Oh, and I have verified that my -deselectAll method works fine. Here's my code: UIImageView *SOCImageView = [[ UIImageView alloc ] initWithImage:[ UIImage imageNamed: @"cancel_wide.png" ] ]; SOItem.leftBarButtonItem = [[ UIBarButtonItem alloc ] initWithCustomView: SOCImageView ]; [ SOCImageView release ]; [ SOItem.leftBarButtonItem setTarget: self ]; [ SOItem.leftBarButtonItem setAction: @selector( deselectAll ) ]; Thanks a million

  • Why does WPF toggle button pulse once unchecked

    - by randyc
    Wihtin a Desktop app I have a toggle button: For the Checked event I am setting a value and then executing a method FilterView(); //ommitting code Unchecked state is just the opposite. resets a variable and executed the method again The question I have is I noticed when I uncheck the toggle button the button continues to pulse or flash ( going from blue to chrome) as if it still has focus. The button will stay like this until another button is clicked. Is there a way to remove this focus so that when the button is unchecked the button goes back to a unchecked state without the flashing / pulsing color. As you can see from above this is a standard toggle button no styles or custom I tested this on just a regular button and I found the same occured when clicked the button will continue to pulse / flash until another button is clicked. How do you work around this or prevent this effect from happening. Thank you

  • Is it fair for us to conclude XOR string encryption is less secure than well known encryption (Say Blowfish)

    - by Yan Cheng CHEOK
    I was wondering, is it fair to conclude, XOR string encryption is less secure than other encryption method, say Blowfish This is because for both methods, their input are Unencrypted string A secret key string XOR(string value,string key) { string retval(value); short unsigned int klen=key.length(); short unsigned int vlen=value.length(); short unsigned int k=0; short unsigned int v=0; for(v;v<vlen;v++) { retval[v]=value[v]^key[k]; k=(++k<klen?k:0); } return retval; } Is there any proof that XOR encryption method is more easy to be "broken" than Blowfish if the same key is being chosen?

  • Why does my UIActivityIndicatorView only display once?

    - by Schwigg
    I'm developing an iPhone app that features a tab-bar based navigation with five tabs. Each tab contains a UITableView whose data is retrieved remotely. Ideally, I would like to use a single UIActivityIndicatorView (a subview of the window) that is started/stopped during this remote retrieval - once per tab. Here's how I set up the spinner in the AppDelegate: - (void)applicationDidFinishLaunching:(UIApplication *)application { [window addSubview:rootController.view]; activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; [activityIndicator setCenter:CGPointMake(160, 200)]; [window addSubview:activityIndicator]; [window makeKeyAndVisible]; } Since my tabs were all performing a similiar function, I created a base class that all of my tabs' ViewControllers inherit from. Here is the method I'm using to do the remote retrieval: - (void)parseXMLFileAtURL:(NSString *)URL { NSAutoreleasePool *apool = [[NSAutoreleasePool alloc] init]; AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; NSLog(@"parseXMLFileAtURL started."); [appDelegate.activityIndicator startAnimating]; NSLog(@"appDelegate.activityIndicator: %@", appDelegate.activityIndicator); articles = [[NSMutableArray alloc] init]; NSURL *xmlURL = [NSURL URLWithString:URL]; rssParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL]; [rssParser setDelegate:self]; [rssParser setShouldProcessNamespaces:NO]; [rssParser setShouldReportNamespacePrefixes:NO]; [rssParser setShouldResolveExternalEntities:NO]; [rssParser parse]; NSLog(@"parseXMLFileAtURL finished."); [appDelegate.activityIndicator stopAnimating]; [apool release]; } This method is being called by each view controller as follows: - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; if ([articles count] == 0) { NSString *path = @"http://www.myproject.com/rss1.xml"; [self performSelectorInBackground:@selector(parseXMLFileAtURL:) withObject:path]; } } This works great while the application loads the first tab's content. I'm presented with the empty table and the spinner. As soon as the content loads, the spinner goes away. Strangely, when I click the second tab, the NSLog messages from the -parseXMLFileAtURL: method show up in the log, but the screen hangs on the first tab's view and I do not see the spinner. As soon as the content is done downloading, the second tab's view appears. I suspect this has something to do with threading, with which I'm still becoming acquainted. Am I doing something obviously wrong here?

  • Subclass of Subclass fluent nHibernate

    - by Xavier Hayoz
    Hi all My model looks like this: public class SelectionItem : BaseEntity // BaseEntity ==> id, timestamp stuff {//blabla} public class Size : SelectionItem {//blabla} public class Adultsize : Size {//blabla} I would like to use class-hierarchy-per-table-method of fluent nhibernate public class SelectionItemMap : BaseEntityMap<Entities.SelectionItem.SelectionItem> { public SelectionItemMap() { Map(x => x.Name); Map(x => x.Picture); Map(x => x.Code); DiscriminateSubClassesOnColumn("SelectionItemType"); } } and reset a DiscriminateSubClassesOnColumn on the following subclass: public class SizeMap : SubclassMap<Size> { DiscriminateSubClassesOnColumn("SizeType") } public Adultsize : SubclassMap<Adultsize> {} But this doesn't work. I found a solution on the web: link text but this method is depreciated according to resharper. How to solve it? thank you for further informations.

  • Limit number of charchters in uitextview !

    - by hib
    Hello All , I am giving a text view to tweet some string . I am applying the following method to restrict the number of characters to 140 in length. - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{ if([text isEqualToString:@"\b"]){ DLog(@"Ohoooo"); return YES; }else if([[textView text] length] > 140){ return NO; } return YES; } The code is working nicely except the first condition that backspace is not working. suppose that I have reached the limit of 140 characters so that the method will give me false and the user can not insert more characters but after that when I try to delete some characters the text view behave as it is disabled . So the question how do delete characters from textview.text or re-enable the text view .

  • Delphi Prism getting Unknown Identifier "DllImport" error

    - by Robo
    I'm trying to call Window's SendMessage method in Delphi Prism, I've declared the class as follow: type MyUtils = public static class private [DllImport("user32.dll", CharSet := CharSet.Auto)] method SendMessage(hWnd:IntPtr; Msg:UInt32; wParam:IntPtr; lParam:IntPtr):IntPtr; external; protected public end; When I tried to compile, I get the error Unknown identifier "DllImport" I used this as an example, http://stackoverflow.com/questions/2708520/how-to-call-function-createprocess-in-delphi-prism and the syntax looks the same. Is there a setting I need to enable, or do I have a syntax error?

  • _mask and Rails

    - by Eric Koslow
    So I am trying to get the cancan gem to work with my rails 3 app and I've hit a problem. I tried to copy the code that Ryan Bates (the creator of the gem) used in his screen cast, but I get an error saying that roles_mask is not a method. I figure that the _mask method was removed from Ruby/Rails at some point, and I'm now wondering what is the replacement. Here's the code in my user.rb model: named_scope :with_role, lambda { |role| {:conditions => "roles_mask & #{2**ROLES.index(role.to_s)} > 0 "} } ROLES = %w[admin student principal admissions] def roles=(roles) self.roles_mask = (roles & ROLES).map { |r| 2**ROLES.index(r) }.sum end def roles ROLES.reject { |r| ((roles_mask || 0) & 2**ROLES.index(r)).zero? } end def role? roles.include? role.to_s end def role_symbols roles.map(&:to_sym) end I'm using Rails 3 and Ruby 1.9.2dev Thank you

  • Gwt-gdata authentication

    - by Raffo
    Hi guys, I'm writing an application with GWT and I found on the internet that there's a library to use easily gdata features. In particular I need to use the integration with Google Calendar. I followed the official guide on gwt-gdata site to do the authentication ( http://code.google.com/p/gwt-gdata/wiki/GettingStarted ) but unfortunately, I got an error. This is the error: 17:59:12.463 [ERROR] [testmappa] Unable to load module entry point class testMappa.client.TestMappa (see associated exception for details) com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.google.accounts is undefined fileName: http://127.0.0.1:8888 lineNumber: 29 stack: ("http://www.google.com/calendar/feeds/")@http://127.0.0.1:8888:29 connect("http://127.0.0.1:8888/TestMappa.html?gwt.codesvr=127.0.0.1:9997","`gL1<a3s4B&Y{(Ci","127.0.0.1:9997","testmappa","2.0")@:0 ((void 0),"testmappa","http://127.0.0.1:8888/testmappa/")@http://127.0.0.1:8888/testmappa/hosted.html?testmappa:264 z()@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:2 (-2)@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:8 at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:195) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.accounts.client.User.login(User.java) at testMappa.client.TestMappa.onModuleLoad(TestMappa.java:68) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.ModuleSpace.onLoad(ModuleSpace.java:369) at com.google.gwt.dev.shell.OophmSessionHandler.loadModule(OophmSessionHandler.java:185) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:380) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:637) I'm not able to understand the reason of this error. My code is simply: String scope = "http://www.google.com/calendar/feeds/"; User.login(scope); And as far as I know it should work as it is. I don't know what to do and I'm here to ask how to solve this problem and if I can directly use gdata native java library, but I believe this other thing is not possible to be done for client-side gwt code (since the code is going to be converted to javascript). Thank you.

  • How to Connect Crystal Reports to MySQL directly by C# code without DSN or a DataSet

    - by Yanko Hernández Alvarez
    How can I connect a Crystal Report (VS 2008 basic) to a MySQL DB without using a DSN or a preload DataSet using C#? I need install the program on several places, so I must change the connection parameters. I don't want to create a DSN on every place, nor do I want to preload a DataSet and pass it to the report engine. I use nhibernate to access the database, so to create and fill the additional DS would take twice the work and additional maintenance later. I think the best option would be to let the crystal reports engine to connect to MySQL server by itself using ODBC. I managed to create the connection in the report designer (VS2008) using the Database Expert, creating an ODBC(RDO) connection and entering this connection string "DRIVER={MySQL ODBC 5.1 Driver};SERVER=myserver.mydomain" and in the "Next" page filling the "User ID", "Password" and "Database" parameters. I didn't fill the "Server" parameter. It worked. As a matter of fact, if you use the former connection string, it doesn't matter what you put on the "Server" parameter, it seems the parameter is unused. On the other hand, if you use "DRIVER={MySQL ODBC 5.1 Driver}" as a connection string and later fill the "Server" parameter with the FQDN of the server, the connection doesn't work. How can I do that by code? All the examples I've seen till now, use a DSN or the DataSet method. I saw the same question posted but for PostgreSQL and tried to adapt it to mysql, but so far, no success. The first method: Rp.Load(); Rp.DataSourceConnections[0].SetConnection("DRIVER={MySQL ODBC 5.1 Driver};SERVER=myserver.mydomain", "database", "user", "pass"); Rp.ExportToDisk(ExportFormatType.PortableDocFormat, "report.pdf"); raise an CrystalDecisions.CrystalReports.Engine.LogOnException during ExportToDisk Message="Logon failed.\nDetails: IM002:[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.\rError in File temporal file path.rpt:\nUnable to connect: incorrect log on parameters. the InnerException is an System.Runtime.InteropServices.COMException with the same message and no InnerException The "no default driver specified" makes me wonder if the server parameter is unused here too (see above). In that case: How can I specify the connection string? I haven't tried the second method because it doesn't apply. Does anybody know the solution?

  • UIPickerView selectedRowInComponent: returns stale data after code adjusts it

    - by Eric Lloyd
    I have a UIPickerView with multiple components. Some values are grayed out, and my pickerView:didSelectRow:inComponent honors this by shifting the picker component in question to the nearest valid value, much as UIDatePicker moves from "30" to "28" when you select "February". Then it calls a delegate method to announce the adjusted value. When my adjuster method calls my UIPickerView's selectRow:inComponent:animated:YES, the value on screen is correct, but the values from selectedRowInComponent: are stale (from before the adjustment for gray values). However, if I call selectRow:inComponent:animated:NO, the returned values are correct, but the lack of animation is jarring. I've tried wrapping the adjustment in a beginAnimations:/commitAnimations block and catching the values in UIView's +animationDidStopSelector, but I still get stale values. Has anyone run into this before?

  • Serializing data using IEnumerable<T> with WebGet

    - by Jim
    possible duplicate: Cannot serialize parameter of type ‘System.Linq.Enumerable… ’ when using WCF, LINQ, JSON Hi, If my method signiature looks like this, it works fine. [WebGet] MyClass[] WebMethod() If the signiature looks like this [WebGet] IEnumerable<T> WebMethod() I get the following error: Cannot serialize parameter of type 'X.Y.Z.T+<WebMethod>d__2c' (for operation 'WebMethod', contract 'IService') because it is not the exact type 'System.Collections.Generic.IEnumerable`1[X.Y.Z.T]' in the method signature and is not in the known types collection. In order to serialize the parameter, add the type to the known types collection for the operation using ServiceKnownTypeAttribute. I have tried adding. ServiceKnownType(typeof(IEnumerable)) Same error. Is this a bug in 2010 beta 2, or is this likely to be correct going forward? Thanks

  • CCSprite following a sequence of CGPoints

    - by pgb
    I'm developing a line drawing game, similar to Flight Control, Harbor Master, and others in the appstore, using Cocos2D. For this game, I need a CCSprite to follow a line that the user has drawn. I'm storing a sequence of CGPoint structs in an NSArray, based on the points I get in the touchesBegin and touchesMoved messages. I now have the problem of how to make my sprite follow them. I have a tick method, that is called at the framerate speed. In that tick method, based on the speed and current position of the sprite, I need to calculate its next position. Is there any standard way to achieve this? My current approach is calculate the line between the last "reference point" and the next one, and calculate the next point in that line. The problem I have is when the sprite "turns" (moves from one segment of the line to another). Any hint will be greatly appreciated.

  • Rendering a derived partial view with Html.RenderPartial

    - by FreshCode
    Calling Html.RenderPartial("~/Views/Payments/MyControl.ascx"); from a view works if Method.ascx is a control that directly inherits System.Web.Mvc.ViewUserControl. However, if the control inherits a new class that derives from System.Web.Mvc.ViewUserControl, the call to Html.RenderPartial("~/Views/Payments/MyDerivedControl.ascx"); fails, reporting that no such view exists. Example derived ViewUserControl: class MyDerivedControl : System.Web.Mvc.ViewUserControl { public Method() { ViewData["SomeData"] = "test"; } } Is there a workaround, or is there another way I should be doing this? Perhaps an HTML helper?

  • Android Service onBind -> onStart

    - by Gernot
    Hello, I have a comprehension question about Android Services. I have a Service that performs background http operations and a Activity that should display the current state of these http operations. So I implementet the Binder interface and so on. I can call the bindService method and onServiceConnected of my ServiceConnnection is getting called. But as far as I know, onBind doesn't calls onStartCommand() and so onStart() of the Service is never called. So how can I call the onStart() method of the service class and start my operations. Or how is the best way to start my operations in the service, when I also want a binding between the Activity and the Service.
