  • Get XAML from WPF Custom RichTextFormat

    - by Erika
    I've looked at other posts, but i cant seem to find something that works. I have a custom control WPF RichTextBox and would like to obtain the XAML from this control. I have tried the following //rt is the name of this particular custom richtextbox TextRange range = new TextRange(rt.Document.ContentStart, rt.Document.ContentEnd); MemoryStream stream = new MemoryStream(); range.Save(stream, DataFormats.Xaml); string xamlText = Encoding.UTF8.GetString(stream.ToArray()); return xamlText; but this doesnt seem to work :s I can access the rt.Document.Content start etc but it seems to crash there "Object Reference not set to instance of an object". I am using the richtextbox directly from the .xaml.cs so it should be initiated and so on :s. Any Ideas or other ways to get the XAML from a richtextbox pls? (i'm requiring the XAML cos i actually want to get the HTML.. if theres some other direct manner perhaps?)

  • How do you handle EF Data Contexts combined with asp.net custom membership/role providers

    - by KallDrexx
    I can't seem to get my head around how to implement a custom membership provider with Entity Framework data contexts into my asp.net MVC application. I understand how to create a custom membership/role provider by itself (using this as a reference). Here's my current setup: As of now I have a repository factory interface that allows different repository factories to be created (right now I only have a factory for EF repositories and and in memory repositories). The repository factory looks like this: public class EFRepositoryFactory : IRepositoryFactory { private EntitiesContainer _entitiesContext; /// <summary> /// Constructor that generates the necessary object contexts /// </summary> public EFRepositoryFactory() { _entitiesContext = new EntitiesContainer(); } /// <summary> /// Generates a new entity framework repository for the specified entity type /// </summary> /// <typeparam name="T">Type of entity to generate a repository for </typeparam> /// <returns>Returns an EFRepository</returns> public IRepository<T> GenerateRepository<T>() where T : class { return new EFRepository<T>(_entitiesContext); } } Controllers are passed an EF repository factory via castle Windsor. The controller then creates all the service/business layer objects it requires and passes in the repository factory into it. This means that all service objects are using the same EF data contexts and I do not have to worry about objects being used in more than one data context (which of course is not allowed and causes an exception). As of right now I am trying to decide how to generate my user and authorization service layers, and have run against a design roadblock. The User/Authization service will be a central class that handles the logic for logging in, changing user details, managing roles and determining what users have access to what. The problem is, using the current methodology the asp.net mvc controllers will initialize it's own EF repository factory via Windsor and the asp.net membership/role provider will have to initialize it's own EF repository factory. This means that each part of the site will then have it's own data context. This seems to mean that if asp.net authenticates a user, that user's object will be in the membership provider's data context and thus if I try to retrieve that user object in the service layer (say to change the user's name) I will get a duplication exception. I thought of making the repository factory class a singleton, but I don't see a way for that to work with castle Windsor. How do other people handle asp.net custom providers in a MVC (or any n-tier) architecture without having object duplication issues?

  • Passing Custom headers from .Net 1.1 client to a WCF service

    - by sreejith
    I have a simple wcf service which uses basicHttp binding, I want to pass few information from client to this service via custom SOAP header. My client is a .net application targetting .Net 1.1, using visual studio I have created the proxy( Added a new web reference pointing to my WCF service) I am able to call methods in the WCF service but not able to pass the data in message header. Tried to override "GetWebRequest" and added custom headers in the proxy but for some reason when I tried to access the header using "OperationContext.Current.IncomingMessageHeaders.FindHeader" it is not thier. Any idea how to solve this prob? This is how I added the headers protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest request; request = (HttpWebRequest)base.GetWebRequest(uri); request.Headers.Add("tesData", "test"); return request; }

  • Default custom ControlTemplate is not applied when using Style

    - by gehho
    Hi all, I have created a default style for a Button including a custom ControlTemplate like so: <Style TargetType="{x:Type Button}"> <Setter Property="OverridesDefaultStyle" Value="True"/> <Setter Property="Background" Value="White"/> <Setter Property="BorderBrush" Value="Black"/> <!-- ...other property setters... --> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <Grid x:Name="gridMain"> <!-- some content here --> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> This style is added to my shared ResourceDictionary which is loaded by every control. Now, this style/template is applied to all my buttons, as expected, but it is NOT applied to those buttons which locally use a different style. For example, I want to have a certain margin for my "OK", "Apply" and "Cancel" buttons. Therefore, I defined the following style: <Style x:Key="OKApplyCancelStyle" TargetType="{x:Type Button}"> <Setter Property="Margin" Value="4,8"/> <Setter Property="Padding" Value="8,6"/> <Setter Property="MinWidth" Value="100"/> <Setter Property="FontSize" Value="16"/> </Style> ...and applied that style to my buttons using a StaticResource: <Button Content="OK" Style="{StaticResource OKApplyCancelStyle}"/> For me, the expected result would be that the ControlTemplate above would still be applied, using the values for Margin, Padding, MinWidth and FontSize from the "OKApplyCancelStyle". But this is not the case. The default Windows ControlTemplate is used instead, using the values from the style. Is this the typical behavior? Does a local style really override a custom ControlTemplate? If so, how can I achieve my desired behavior? I.e. still use my custom ControlTemplate even when styles are defined locally? Many thanks in advance, gehho.

  • Eclipse plugin: Custom icon for a Marker

    - by Itay
    I want to specify a custom icon for a makrer. Sadly, the icon that I chose is not displayed. Here's the relevant parts of the plugin.xml file (the project id "x"): <extension id="xmlProblem" name="XML Problem" point="org.eclipse.core.resources.markers"> <super type="org.eclipse.core.resources.problemmarker"/> <persistent value="true"> </persistent> </extension> <extension point="org.eclipse.ui.ide.markerImageProviders"> <imageprovider markertype="x.xmlProblem" icon="icons/marker.png" id="xmlProblemImageProvider"> </imageprovider> </extension> I also tried specifying a class (implementing IMarkerImageProvider) instead of an icon, but that getImagePath() method of the class does not get called. Any thoughts on how to make custom marker icons work? Desperately, yours. -Itay

  • how to profile silverlight mvvm application with a lot of custom controls

    - by tomo
    There is a quite big LOB silverlight application and we wrote a lot of custom controls which are rather heavy in drawing. All data is loaded by RIA service, processed and bound (using INofityPropertyChanged interface) to the view. The problem is that first drawing takes a lot time. Following calls to the service (server) and redrawing is quite fast. I used Equatec profiler to track the problem. I saw that processing takes a couple of miliseconds only so my idea is that the drawing by SL engine is slow. I'm wondering if it is possible to profile somehow processes inside SL to check which drawing operations are taking too much time. Are there any guidelines how to implement faster drawing of complex custom controls?

  • How to keep the highlight border of a JComponent, when custom border is set

    - by Frederik Wordenskjold
    I have a JTextField, where I've set some custom properties: nameField.setPreferredSize(new Dimension(275,40)); nameField.setBackground(bgColor); nameField.setForeground(txtColor); nameField.setFont(new Font("HelveticaNeue",Font.PLAIN,22)); nameField.setBorder(BorderFactory.createLineBorder(Color.WHITE, 2)); When the component has focus, there is no highlight shown around the field. On a Mac, it is usually a blue glowing rectangle, indicating that this component has focus. If I comment out the nameField.setBorder(...), the highlight reappears. How do I keep the highlight, but also my custom border!? Basically, I just want the highlight-border to show when the component has focus, and no border when the component is unfocused.

  • Create Custom Builds of an Xcode Project

    - by macinjosh
    I am going to build a Mac application written in Obj-C with Xcode. For argument's sake let's say it will have 10 optional features. I need a way to enable or disable those features to create custom builds of the application. These builds would be automated (most likely through the Mac OS X Terminal) so I would need a way to state which of these features are enabled/disabled at build time (a configuration file or CLI arguments would be ideal.) So what is the best way to accomplish this? I'm trying to plan this out before I start coding so that there is proper separation in my code base to allow for these features to come and go. Ideally the custom build would only contain compiled code for the features it should have. In other words I don't want to always compile all the features and condition them out at runtime.

  • Custom view in ListView disappears while scrolling in Android

    - by troorl
    Hi. I wrote a simple custom view for rows in ListView. It works fine, but when I try to scroll the list, I see only white rows without content. And when scrolling is over, rows continue to show again. This is how I draw a custom view: @Override protected void onDraw(Canvas canvas) { if(poster != null) { canvas.drawBitmap(poster, padding, padding, paint); } canvas.drawText(title, 55 + padding, 16 + padding, paint); } Maybe I missed something? P.S. This is short screencast (400kb) http://dl.dropbox.com/u/190203/test.mpeg

  • Accessing the Custom Object Return type from ojdbc6 JDBC Thin Drivers

    - by Andrew Harmel-Law
    I'm writing some JDBC code which calls a Oracle 11g PL/SQL procdedure which has a Custom Object return type. I can get the code to call the procedure, but how do I access the returned Custom Object to obtain it's contained values?. An example of my code calling the procedure is below: PLSQL Code: Procedure GetDataSummary (p_my_key IN KEYS.MY_KEY%TYPE, p_recordset OUT data_summary_tab, p_status OUT VARCHAR2); Java Code: String query = "begin manageroleviewdata.getdatasummary(?, ?, ?); end;"); CallableStatement stmt = conn.prepareCall(query); stmt.setInt(1, 83); stmt.registerOutParameter(2, OracleTypes.ARRAY, "DATA_SUMMARY_TAB"); stmt.registerOutParameter(3, OracleTypes.VARCHAR); stmt.execute(stmt); How do I get the result back fron this?

  • Android: Registering ContextMenu for a Custom ListAdapter

    - by primal
    Hi, I made a custom list adapter extending the Base adapter. Each item in the list has an imagebutton, 2 textviews and a button. I tried to add the context menu to the list so as to display some options for an item in the list. registerForContextMenu(getListView()); I used a MenuInflater object to inflate the context menu xml file. But on clicking the items in the list nothing shows up or the usual highlighting of the item of list on click isn't shown. Is it that the context menu doesn't work for custom list views? Any help would be much appreciated. Regards, Primal

  • Embedded AXIS2: Serving a custom WSDL

    - by Maik
    I am using a console app that starts several axis instances without using a packages archive. Like this: AxisService axisService2 = AxisService.createService( new Myclass.getClass().getName(), axisConfigurationContext.getAxisConfiguration()); axisService2.addParameter(new Parameter("useOriginalwsdl", "true")); axisConfigurationContext.getAxisConfiguration().addService(axisService2); Now, I need to serve a custom WSDL. I tried adding a META-INF folder to the bin-root, and in various other places, but with no success. How do I specify in this case the location of a custom WSDL? Thanks!

  • Regex Pattern for ignoring a custom escape character

    - by user1517464
    I am trying to find a suitable regex for matching pair of custom characters in an input string. These custom characters are replaced by their corresponding html tags. For e.g. The input string can have underscores in pairs to indicate words in bold. Hence, _Name_ outputs as <b>Name</b> However if there is a genuine underscore in the string, it cannot be replaced by "bold" tags and has to be ignored. The genuine underscore has to be preceded by / (I couldn't find a better character, it could be one more underscore or hyphen or whatever). Any single or paired occurrance of this genuine underscore has to be ignored by regex. So far I could come up with this regex: var pattern = @"(?!/)_(.*?)(?!/)_"; But it fails in below input string: _Tom_Katy/_Richard/_/_Stephan_and many users It outputs as <b>Tom</b>Katy/<b>Richard/_/</b>Stephan_and many users Many Thanks in Advance, Pr

  • Using Custom HttpHandler to redirect users in Sharepoint

    - by BeraCim
    Hi all: I need to redirect a user to a different page if they visit a certain set of pages in a web. There is one condition: I'm not allowed to touch the IIS. I have googled around and found a thing called the custom HttpHandler for WSS 3.0. It sounded like something that I can use to capture the URL the user enters (the most malicious way to get to a page that should really be redirected) and redirect them to another page/web. But having not have the chance to use it yet, I was wondering am I on the right track by using a Custom HttpHandler to redirect a user to a different page in Sharepoint using C#? Many thanks.

  • Custom UITableviewcell shows "fatal error: Can't unwrap Optional.None" issue in swift

    - by user1656286
    I need to load a custom cell in a UITableView. I created a custom subclass of UITableViewCell named "CustomTableViewCell". I have added a UITabelViewCell to the tableview (using drag and drop) as shown in figure. Then in file inspector I set the class of that UITabelViewCell to be "CustomTableViewCell". Here is my code: class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { @IBOutlet var tableView : UITableView var items = String[]() override func viewDidLoad() { super.viewDidLoad() items = ["Hi","Hello","How"] self.tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "CusTomCell") // Do any additional setup after loading the view, typically from a nib. } func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{ return items.count } func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!{ var cell:CustomTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("CusTomCell") as CustomTableViewCell cell.labelTitle.text = items[indexPath.row] return cell; } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } When I run my code, I get the following error: "fatal error: Can't unwrap Optional.None" as seen in the image.

  • NSPredicates with custom objects

    - by Horatiu Paraschiv
    Hi, I have the following problem and I cannot figure out how to solve it. I have an NSSet which contains Person objects (NSDictionary with 2 keys: name, age). From time to time I get an NSArray of Person objects and I want to add them to my NSSet but I want to filter out the duplicates. I'm thinking I could use NSPredicates but I am reading the documentation and I can't understand how should I format my NSPredicate to filter out my array content based on what I already have in NSSet. So I have an NSSet with 5 custom objects and I get an NSArray with 6 objects but 3 of them already exist in NSSet and I want to filter them out. I understand what I should do with basic objects like Strings, integers, etc but I don't know how to extend this to work with custom more complex objects. I hope I was clear enough with my problem. Any starting point, example or advice is much appreciated. Thank you!

  • Blackberry custom slideshow-style BitmapField manager

    - by Diego Tori
    Right now, I'm trying to figure out how to implement the following: Suppose I have a custom Manager that has about 10 or so BitmapFields layed out in a horizontal manner (similar to a slideshow contained in a HFM ) . What I want to achieve is to be able to move the image HFM via touchEvent horizontally, where a BitmapField would take focus on the left-hand side of the custom Manager. In other words, will I have to give a value to setHorizontalScroll and if so, is it a matter of just incrementing that value when the user makes a left or right touch event. Also, how can I get the focus of a Field within a given position on the screen (i.e. the left-most Field on the HFM) when the HFM is scrolling sideways via touchEvent?
