  • How do I format a Uri when binding an Image in Silverlight?

    - by Scott
    I haven't been able to find an answer to this. I have a database that has image paths in it ("images/myimage.jpg"). These images exist on my asp.net site which is also where I host the SL. I want to bind these images to my ListBox control so that the image displays. I have read that since I have a string value, "images/myimage.jpg", that I need to convert it to a BitMap image. I have done this: the xaml: <Image Source="{Binding ImageFile, Converter={StaticResource ImageConverter}}"/> the ImageConverter class: public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { try { Uri source= new Uri(value.ToString()); return new BitmapImage(source); } catch(Exception ex) { return new BitmapImage(); } } I get an error when creating the Uri, "The Format of the URI could not be determined". What am I doing wrong? If I create a Uri that looks like this: http://localhost:49723/images/myimage.jpg, it works just fine. Why doesn't just "images/myimage.jpg" work?

  • jQuery: Post form to a modal window for previewing the entered data

    - by superUntitled
    I am looking for a way to use jQuery to allow a user to look at a modal window "preview" of a form before they submit the form to be saved. I have this working with javascript, the form is posted to a file named preview.php that iterates through the posted information. The script currently opens a new window. I would like instead to use jQuery to post the form to a modal window for previewing. Does anyone have any thoughts on how to do this? This is what I am currently using: <script language="JavaScript"> function preview(form) { form.target='_blank'; form.action='http://example.com/preview.php'; form.submit(); } </script> <input type="button" value="preview" onclick='preview(this.form)'>

  • IE6 is duplicating characters, can't figure out why. Suggestions?

    - by Paul
    Problem is located on http://www.preownedweddingdresses.com/ We have a dresses slider at the bottom, select tabs different dresses shown. Works fine everywhere else, but for some reason, in IE6, the letters "ls" (from the tab "Best Deals") are duplicating inside the content and causing rendering issues. I've yet to find anything that can fix this, or anything that can be blamed for causing this either. I've changed the letters at the end of Best Deals, and the duplicated letters change as well. Open to any suggestions.

  • possibility to do type/data conversion of data returned by ria services?

    - by reinier
    My service returns an byte array, which I have to convert to an 'animated gif' (using imagetools since silverlight doesn't support it yet) I was wondering, is it possible to insert some code at the client, where I can do the conversion before the actual object is returned to whatever it is binded against? On the server side, the queries can be customized before it is sent over the wire. I'm asking for the exact opposite, can I do some on the fly conversions the moment they get of the wire and before they are returned to the controls. If I'm overthinking this and there is a smarter/better/easier way to do it, I'm all for such an answer as well

  • How do you manage web navigation info in your application?

    - by Dave
    I’m building an application where different users will have different menu items available to them depending on what they’ve paid for. There will also be multiple levels to the menu hierarchy. What’s the best approach to this problem? I’m assuming I need a database table that represents the menu hierarchy, including the parent-child relationships of the nodes in the navigation as well as the sorting of the items. Then another table which I use to manage whether a user is authorized to access a particular item in that table. When I render the view, I’d reference the menus, and the access rights of the user to output the menu, and I’d also need a function to check that same authorization from each controller in case a user manually types in a URL of a controller they’re not supposed to have access to. Is this the right approach? Any suggestions for caching this to prevent the constant look-ups of this type of info? I’m open to any suggestions on how you may have approached this type of requirement.

  • Inability to detect the Output from inside a SSIS script component

    - by Danaja
    In the script of the script components the Output buffer is not being detected as an existing component. I am trying to use the following piece of code Output0Buffer.AddRow(); within the public override void Input0_ProcessInputRow(Input0Buffer Row) method. I know it should be available within this method because at the moment I am copying and using a component from a previous project that has this code and it works. but when I create a new component and put the same code in it doesn't Can any one explain why this is happening?

  • Take data from an XML file and put it into a MySQL database

    - by Aidan
    Hi Guys, I'm looking to construct a script that would go through an XML file. Would find specific tags in it, put them in a table and fill the table with specific tags within them. I'm using MySQL 5.1 so loadXML isn't an option and I think that ExtractData() method wont be much use either.. but I don't really know. What would be the best way to go about this?

  • How to normalize SVG path data (cross browser)?

    - by Timo
    I have tried to find a way to implement cross browser path normalizer. There IS a native way which is described here and functional example is here, but it works only in newest Opera (but not in IE, FF, Safari, Chrome). The native way uses pathElm.normalizedPathSegList and it converts all relative coordinates to absolute ones and represents all path segment types as a following subset of types: M,L,C,z. I have found only one javascript code and jsfiddled functional example of it, but it works only in IE and FF. Chrome gives "Uncaught Error: INDEX_SIZE_ERR: DOM Exception 1". How this could be fixed to work also in Opera, Safari and Chrome or is there any other way for normalizing SVG paths?

  • Cannot perform an ORDERBY against my EF4 data

    - by Jaxidian
    I have a query hitting EF4 using STEs and I'm having an issue with user-defined sorting. In debugging this, I have removed the dynamic sorting and am hard-coding it and I still have the issue. If I swap/uncomment the var results = xxx lines in GetMyBusinesses(), my results are not sorted any differently - they are always sorting it ascendingly. FYI, Name is a varchar(200) field in SQL 2008 on my Business table. private IQueryable<Business> GetMyBusinesses(MyDBContext CurrentContext) { var myBusinesses = from a in CurrentContext.A join f in CurrentContext.F on a.FID equals f.id join b in CurrentContext.Businesses on f.BID equals b.id where a.PersonID == 52 select b; var results = from r in myBusinesses orderby "Name" ascending select r; //var results = from r in results // orderby "Name" descending // select r; return results; } private PartialEntitiesList<Business> DoStuff() { var myBusinesses = GetMyBusinesses(); var myBusinessesCount = GetMyBusinesses().Count(); Results = new PartialEntitiesList<Business>(myBusinesses.Skip((PageNumber - 1)*PageSize).Take(PageSize).ToList()) {UnpartialTotalCount = myBusinessesCount}; return Results; } public class PartialEntitiesList<T> : List<T> { public PartialEntitiesList() { } public PartialEntitiesList(int capacity) : base(capacity) { } public PartialEntitiesList(IEnumerable<T> collection) : base(collection) { } public int UnpartialTotalCount { get; set; } }

  • Building Outline Data in Google Maps (Android)

    - by scotty.hoag
    I'm working on an Android project that focuses on knowing how close you are to buildings. I wanted to know if there is some way to extract the geographic information about the outlines of buildings out of the Google Maps API. Thanks. EDIT: The functionality I'm looking for is similar to what's going on in this app. (Click the link near the top of the page that says "View Live Sample".) http://resources.esri.com/help/9.3/arcgisserver/apis/javascript/gmaps/help/google_start.htm#topics/samples/identify_features.html

  • How to print structures in PLT Scheme so as to display their fields?

    - by tkf
    I would like code like this: (define-struct thing (a b c)) (define th (make-thing 1 2 3)) to print something like this: (make-thing 1 2 3) when I type "th" into either the DrScheme or MzScheme repl. I am using the language "pretty big" in DrScheme with output style set to "constructor". This is what I get in DrScheme: (make-thing ...) (i literally get the three dots) In MzScheme: #<thing>

  • DataGrid : Binding with two different classes with lists ? WPF C#

    - by MyRestlessDream
    It is my first question on StackOverflow so I hope I am doing nothing wrong ! Sorry if it is the case ! I need some help because I can not find the solution of my problem. Of course I have searched everywhere on the web but I can not find it (can not post the links that I am using because of my low reputation :( ). Moreover, I am new in C# and WPF (and self-learning). I used to work in C++/Qt so I do not know how everything works in WPF. And sorry for my English, I am French. My problem My basic classes are that an Employee can use a computer. The id of the computer and the date of use are stored into the class Connection. I would like to display the list information in a DataGrid and in RowDetailsTemplate like here : http://i.stack.imgur.com/Bvn1z.png So it will do a binding to the Employee class but also to the Connection class with only the last value of the property (here the last value of the list "Computer ID" and the last value of the list "Connection Date" on this last computer). So it is a loop in the different lists. How can I do it ? Is it too much to do ? :( I succeed to get the Employee informations but I do not know how to bind the list of computer. When I am trying, it shows me "(Collection)" so it does not go inside the list :( Summary of Questions How to display/bind a value from a list AND from a different class in a DataGrid ? How to display all the values of a list into the RowDetailsTemplate ? Under Windows 7 and Visual Studio 2010 Pro version. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ EDIT ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution I have used the solution of Stefan Denchev. Here the modification of my class : http://i.stack.imgur.com/Ijx5i.png And the code used: <DataGrid ItemsSource="{Binding}" Name="table"> <DataGrid.Columns> <DataGridTextColumn Header="First Name" Binding="{Binding FirstName}"/> <DataGridTextColumn Header="Last Name" Binding="{Binding LastName}"/> <DataGridTextColumn Header="Gender" Binding="{Binding Gender}"/> <DataGridTextColumn Header="Last computer used" Binding="{Binding LastComputerID}"/> <DataGridTextColumn Header="Last connection date" Binding="{Binding LastDate}"/> </DataGrid.Columns> <DataGrid.RowDetailsTemplate> <DataTemplate> <DataGrid ItemsSource="{Binding ListOfConnection}"> <DataGrid.Columns> <DataGridTextColumn Header="Computer ID" Binding="{Binding ComputerID}"/> <DataGridTemplateColumn> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <ListView ItemsSource="{Binding ListOfDate}"/> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> </DataGrid.Columns> </DataGrid> </DataTemplate> </DataGrid.RowDetailsTemplate> </DataGrid> With in code behind : List<Employee> allEmployees = WorkflowMgr.Instance.AllEmployees; table.DataContext = allEmployees; And it works ! I have tryed to improve my fake example :) Hope it will help to another developer !

  • Extracting data form XML file with SimpleXML in PHP

    - by Cudos
    Introduction: I want to loop through XML files with flexible categories structure. Problem: I don't know to loop through a theoretical infinte subcategories without having to make x amount of "for each" statements (See coding example in the bottom). How do I dynamically traverse the categories structure? What I have now: I have no problem looping through XML files with a set structure: <catalog> <category name="Category - level 1"> <category name="Category - level 2"> <category name="Category - level 3" /> </category> <category name="Category - level 2"> <category name="Category - level 3" /> </category> </category> </catalog> Coding example: //$xml holds the XML file foreach ( $xml AS $category_level1 ) { echo $category_level1['name']; foreach ( $category_level1->category AS $category_level2 ) { echo $category_level2['name']; foreach ( $category_level2->category AS $category_level3 ) { echo $category_level3['name']; } } }

    - by ion
    There are 2 Models: Project & Category that are bind with HABTM relationship. I would like to perform a search from projects controller that can do the following: FIND all DISTINCT Project.scedule WHERE Category.slug != 'uncategorised' Apologies for the syntax, I'm no sequel expert. What I have managed to do is to retrieve all projects that do not belong to Category uncategorised into an array however I'm not sure as to how to search again the array result for DISTINCT Project.schedule values (needed to fill out a form drop down) I hope I made myself clear.

  • hierarchical data from self referencing table in tree form

    - by Beta033
    It looks like this has been asked and answered in all the simple cases, excluding the one that I'm having trouble with. I've tried using a recursive CTE to generate this; however maybe a cursor would be better? Or maybe a set of recursive functions will do the trick? Can this be done in a cte? consider the following table PrimaryKey ParentKey 1 NULL 2 1 3 6 4 7 5 2 6 1 7 NULL should yield PK 1 -2 --5 -6 --3 7 -4 where the number of - marks equal the depth, my primary difficulty is the ordering.

  • Handling large (object) datasets with PHP

    - by Aron Rotteveel
    I am currently working on a project that extensively relies on the EAV model. Both entities as their attributes are individually represented by a model, sometimes extending other models (or at least, base models). This has worked quite well so far since most areas of the application only rely on filtered sets of entities, and not the entire dataset. Now, however, I need to parse the entire dataset (IE: all entities and all their attributes) in order to provide a sorting/filtering algorithm based on the attributes. The application currently consists of aproximately 2200 entities, each with aproximately 100 attributes. Every entity is represented by a single model (for example Client_Model_Entity) and has a protected property called $_attributes, which is an array of Attribute objects. Each entity object is about 500KB, which results in an incredible load on the server. With 2000 entities, this means a single task would take 1GB of RAM (and a lot of CPU time) in order to work, which is unacceptable. Are there any patterns or common approaches to iterating over such large datasets? Paging is not really an option, since everything has to be taken into account in order to provide the sorting algorithm.
