  • 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?

  • 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

  • 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?

  • SSRS - Checking whether the data is null

    - by NLV
    Hello I've the following expression in my report. =FormatNumber(MAX(Fields!Reading.Value, "CellReading_Reading"),3) Now when the dataset is empty 'Fields!Reading.Value' becomes empty and finding their maximum is invalid. How can i check if the entire column is empty? I tried the following with no luck. =iif(IsNothing(Fields!.Reading.Value),"",FormatNumber(MAX(Fields!Reading.Value, "CellReading_Reading"),3)) But still i'm getting #Error in the report. I also checked out link and was not able to get a clue from it. I want to handle it in the report level. Thank you. NLV

  • Unserialize data and check it against an id in MySQL

    - by kylex
    I have a row of IDs in a database that has been serialized. What I'm trying to do is check those serialized IDs against a known ID to see if it should be excluded or not. for example: "SELECT * FROM mydb WHERE id = 4 AND checkID != 'an id in the serialized column' " What's the best way to go about this?

  • Iterate Through JSON Data for Specific Element - Similar to XPath

    - by Highroller
    I am working on an embedded system and my theory of the overall process follows this methodology: 1. Send a command to the back end asking for account information in JSON format. 2. The back end writes a JSON file with all accounts and associated information (there could be 0 to 16 accounts). 3. Here's where I get stuck - use JavaScript (we are using the JQuery library) to iterate through the returned information for a specific element (similar to XPath) and build an array based on the number of elements found to populate a drop-down box to select the account you want to view and then do stuff with the account info. So my code looks like this: loadAccounts = function() { $.getJSON('/info?q=voip.accounts[]', function(result) { var sipAcnts = $("#sipacnts"); $(sipAcnts).empty(); // empty the dropdown (if necessarry) // Get the 'label' element and stick it in an array // build the array and append it to the sipAcnts dropdown // use array index to ref the accounts info and do stuff with it } So what I need is the JSON version of XPath to build the array of voip.accounts.label. The first account info looks something like this: { "result_set": { "voip.accounts[0]": { "label": "Dispatch1", "enabled": true, "user": "1234", "name": "Jane Doe", "type": "sip", "sip": { "lots and lots of stuff": }, } } } Am I over complicating the issue? Any wisdom anyone could thrown down would be greatly appreciated.

  • 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.

  • Cakephp, Retreive Data for HABTM Models using conditional find

    - 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.

  • 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; } }

  • ASP.NET DynamicData: Whats happening during an update?

    - by Jens A.
    I am using ASP.NET DynamicData (based on LINQ to SQL) on my site for basic scaffolding. On one table I have added additional properties, that are not stored in the table, but are retrieved from somewhere else. (Profile information for a user account, in this case). They are displayed just fine, but when editing these values and pressing "Update", they are not changed. Here's what the properties look like, the table is the standard aspnet_Users table: public String Address { get { UserProfile profile = UserProfile.GetUserProfile(UserName); return profile.Address; } set { UserProfile profile = UserProfile.GetUserProfile(UserName); profile.Address = value; profile.Save(); } } When I fired up the debugger, I've noticed that for each update the set accessor is called three times. Once with the new value, but on a newly created instance of user, then once with the old value, again on an new instance, and finally with the old value on the existing instance. Wondering a bit, I checked with the properties created by the designer, and they, too, are called three times in (almost) the same fashion. The only difference is, that the last call contains the new value for the property. I am a bit stumped here. Why three times, and why are my new properties behaving differently? I'd be grateful for any help on that matter! =)

  • how to store data crawled from website

    - by Richard
    I want to crawl a website and store the content on my computer for later analysis. However my OS file system has a limit on the number of sub directories, meaning storing the original folder structure is not going to work. Suggestions? Map the URL to some filename so can store flatly? Or just shove it in a database like sqlite to avoid file system limitations?

  • 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?

  • 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?

  • 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']; } } }

  • 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.

  • 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>
