  • Recommendations of a high volume log event viewer in a Java enviroment

    - by Thorbjørn Ravn Andersen
    I am in a situation where I would like to accept a LOT of log events controlled by me - notably the logging agent I am preparing for slf4j - and then analyze them interactively. I am not as such interested in a facility that presents formatted log files, but one that can accept log events as objects and allow me to sort and display on e.g. threads and timelines etc. Chainsaw could maybe be an option but is currently not compatible with logback which I use for technical reasons. Is there any project with stand alone viewers or embedded in an IDE which would be suitable for this kind of log handling. I am aware that I am approaching what might be suitable for a profiler, so if there is a profiler projekt suitable for this kind of data acquisition and display where I can feed the event pipe, I would like to hear about it). Thanks for all feedback Update 2009-03-19: I have found that there is not a log viewer which allows me to see what I would like (a visual display of events with coordinates determined by day and time, etc), so I have decided to create a very terse XML format derived from the log4j XMLLayout adapted to be as readable as possible while still being valid XML-snippets, and then use the Microsoft LogParser to extract the information I need for postprocessing in other tools.

  • MVC.NET custom validator is not working

    - by IvanMushketyk
    I want to write a custom validator for MVC.NET framework that checks if entered date is in the future. To do it, I wrote the following class: [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)] public sealed class InTheFutureAttribute : ValidationAttribute, IClientValidatable { private const string DefaultErrorMessage = "{0} should be date in the future"; public InTheFutureAttribute() : base(DefaultErrorMessage) { } public override string FormatErrorMessage(string name) { return string.Format(ErrorMessageString, name); } public override bool IsValid(object value) { DateTime time = (DateTime)value; if (time < DateTime.Now) { return false; } return true; } public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { var clientValidationRule = new ModelClientValidationRule() { ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()), ValidationType = "wrongvalue" }; return new[] { clientValidationRule }; } } and added attribute to field that I want to check. On the View page I create input field in the following way: <div class="editor-label-search"> @Html.LabelFor(model => model.checkIn) </div> <div class="editor-field-search-date"> @Html.EditorFor(model => model.checkIn) <script type="text/javascript"> $(document).ready(function () { $('#checkIn').datepicker({ showOn: 'button', buttonImage: '/Content/images/calendar.gif', duration: 0, dateFormat: 'dd/mm/yy' }); }); </script> @Html.ValidationMessageFor(model => model.checkIn) </div> When I submit the form for the controller that requires model with checked attribute code in my validator is called and it returns false, but instead of displaying an error it just call my controller's action and send invalid model to it. Am I doing something wrong? How can I fix it? Thank you in advance.

  • Optimizing C# code in MVC controller

    - by cc0
    I am making a number of distinct controllers, one relating to each stored procedure in a database. These are only used to read data and making them available in JSON format for javascripts. My code so far looks like this, and I'm wondering if I have missed any opportunities to re-use code, maybe make some help classes. I have way too little experience doing OOP, so any help and suggestions here would be really appreciated. Here is my generalized code so far (tested and works); using System; using System.Configuration; using System.Web.Mvc; using System.Data; using System.Text; using System.Data.SqlClient; using Prototype.Models; namespace Prototype.Controllers { public class NameOfStoredProcedureController : Controller { char[] lastComma = { ',' }; String oldChar = "\""; String newChar = "&quot;"; StringBuilder json = new StringBuilder(); private String strCon = ConfigurationManager.ConnectionStrings["SomeConnectionString"].ConnectionString; private SqlConnection con; public StoredProcedureController() { con = new SqlConnection(strCon); } public string do_NameOfStoredProcedure(int parameter) { con.Open(); using (SqlCommand cmd = new SqlCommand("NameOfStoredProcedure", con)) { cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@parameter", parameter); using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { json.AppendFormat("[{0},\"{1}\"],", reader["column1"], reader["column2"]); } } con.Close(); } if (json.Length.ToString().Equals("0")) { return "[]"; } else { return "[" + json.ToString().TrimEnd(lastComma) + "]"; } } //http://host.com/NameOfStoredProcedure?parameter=value public ActionResult Index(int parameter) { return new ContentResult { ContentType = "application/json", Content = do_NameOfStoredProcedure(parameter) }; } } }

  • Oracle command hangs when using view for "WHILE x IN..." subquery

    - by Calvin Fisher
    I'm working on a web service that fetches data from an oracle data source in chunks and passes it back to an indexing/search tool in XML format. I'm the C#/.NET guy, and am kind of fuzzy on parts of Oracle. Our Oracle team gave us the following script to run, and it works well: SELECT ROWID, [columns] FROM [table] WHERE ROWID IN ( SELECT ROWID FROM ( SELECT ROWID FROM [table] WHERE ROWID > '[previous_batch_last_rowid]' ORDER BY ROWID ) WHERE ROWNUM <= 10000 ) ORDER BY ROWID 10,000 rows is an arbitrary but reasonable chunk size and ROWID is sufficiently unique for our purposes to use as a UID since each indexing run hits only one table at a time. Bracketed values are filled in programmatically by the web service. Now we're going to start adding views to the indexing, each of which will union a few separate tables. Since ROWID would no longer function as a unique identifier, they added a column to the views (VIEW_UNIQUE_ID) that concatenates the ROWIDs from the component tables to construct a UID for each union. But this script does not work, even though it follows the same form as the previous one: SELECT VIEW_UNIQUE_ID, [columns] FROM [view] WHERE VIEW_UNIQUE_ID IN ( SELECT VIEW_UNIQUE_ID FROM ( SELECT VIEW_UNIQUE_ID FROM [view] WHERE ROWID > '[previous_batch_last_view_unique_id]' ORDER BY VIEW_UNIQUE_ID ) WHERE ROWNUM <= 10000 ) ORDER BY VIEW_UNIQUE_ID It hangs indefinitely with no response from the Oracle server. I've waited 20+ minutes and the SQLTools dialog box indicating a running query remains the same, with no progress or updates. I've tested each subquery independently and each works fine and takes a very short amount of time (<= 1 second), so the view itself is sound. But as soon as the inner two SELECT queries are added with "WHERE VIEW_UNIQUE_ID IN...", it hangs. Why doesn't this query work for views? In what important way are they not interchangeable here?

  • PDF to PNG Processor - Paperclip

    - by Josh Crowder
    I am trying to develop a system in which a user can upload a slideshow (pdf) and it'll export each slide as a png. After some digging around I came across a post on here that suggested using a processor. I've had a go, but I cant get the command to run, if it is running then I don't know what is happening because no errors are being shown. Any help would be appreciated! module Paperclip class Slides < Processor def initialize(file, options = {}, attachment = nill) super @file = file @instance = options[:instance] @current_format = File.extname(@file.path) @basename = File.basename(@file.path, @current_format) end def make dst = Tempfile.new( [ @basename, @format].compact.join(".")) dst.binmode command = <<-end_command -size 640x300 #{ File.expand_path(dst.path) } tester.png end_command begin success = Paperclip.run("convert", command.gsub(/\s+/, " "))) rescue PaperclipCommandLineError raise PaperclipError, "There was an error processing the thumbnail for #{@basename}" end end end end I think my problem is with the convert command... When I run that command by hand, it works but it doesn't give the details of each slide it just executes it. What I need to happen is once its made all the slides, pass back the data to a new model... or I know where all the slides are, but once I get to that point I'm not sure what todo.

  • String Manipulation: Splitting Delimitted Data

    - by Milli Szabo
    I need to split some info from a asterisk delimitted data. Data Format: NAME*ADRESS LINE1*ADDRESS LINE2 Rules: 1. Name should be always present 2. Address Line 1 and 2 might not be 3. There should be always three asterisks. Samples: MR JONES A ORTEGA*ADDRESS 1*ADDRESS2* Name: MR JONES A ORTEGA Address Line1: ADDRESS 1 Address Line2: ADDRESS 2 A PAUL*ADDR1** Name: A PAUL Address Line1: ADDR1 Address Line2: Not Given My algo is: 1. Iterate through the characters in the line 2. Store all chars in a temp variables until first * is found. Reject the data if no char is found before first occurence of asterisk. If some chars found, use it as the name. 3. Same as step 2 for finding address line 1 and 2 except that this won't reject the data if no char is found My algo looks ugly. The code looks uglier. Spliting using //* doesn't work either since name can be replaced with address line 1 if the data was *Address 1*Address2. Any suggestion?

  • How do I build a JSON object to send to an AJAX WebService?

    - by Ben McCormack
    After trying to format my JSON data by hand in javascript and failing miserably, I realized there's probably a better way. Here's what the code for the web service method and relevant classes looks like in C#: [WebMethod] public Response ValidateAddress(Request request) { return new test_AddressValidation().GenerateResponse( test_AddressValidation.ResponseType.Ambiguous); } ... public class Request { public Address Address; } public class Address { public string Address1; public string Address2; public string City; public string State; public string Zip; public AddressClassification AddressClassification; } public class AddressClassification { public int Code; public string Description; } The web service works great with using SOAP/XML, but I can't seem to get a valid response using javascript and jQuery because the message I get back from the server has a problem with my hand-coded JSON. I can't use the jQuery getJSON function because the request requires HTTP POST, so I'm using the lower-level ajax function instead: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "http://bmccorm-xp/HBUpsAddressValidation/AddressValidation.asmx/ValidateAddress", data: "{\"Address\":{\"Address1\":\"123 Main Street\",\"Address2\":null,\"City\":\"New York\",\"State\":\"NY\",\"Zip\":\"10000\",\"AddressClassification\":null}}", dataType: "json", success: function(response){ alert(response); } }) The ajax function is submitting everything specified in data:, which is where my problem is. How do I build a properly formatted JSON object in javascript so I can plug it in to my ajax call like so: data: theRequest I'll eventually be pulling data out of text inputs in forms, but for now hard-coded test data is fine. How do I build a properly formatted JSON object to send to the web service?

  • How to get a fully transparent backbuffer in directx 9 without vista Desktop Window Manager

    - by flawlesslyfaulted
    I currently have an activex control that initiates a media (video/audio) framework another development group in my company developed and I am providing a window handle to that code. That handle is being used by their rendering plugin in the pipeline that uses Direct3d for rendering the video using that handle. I have seperate LPDIRECT3D9EX and LPDIRECT3DDEVICE9EX pointers that I initialize in my activex control. I am trying to clear a backbuffer to transparent and then use directx drawing primatives to draw on that backbuffer producing a transparent window with my drawing primatives over the streaming video on the directx surface below. It appears that clearing a device backbuffer with full alpha transparency is ignored by directx. d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_RGBA(0, 0, 1, 0 /*full alpha*/), 1.0f, 0); I can see the object I draw but they are drawn on top of a backbuffer that has the RGB color specified without the alpha value. The project linked (http://www.codeproject.com/KB/directx/umvistad3d.aspx) to in the stackoverflow question below does what I want but requires vista's Desktop Window Manager and won't work for XP. http://stackoverflow.com/questions/148275/how-do-i-draw-transparent-directx-content-in-a-transparent-window I have tried with D3DRS_ALPHABLENDENABLE true with configured blend with no avail. I have also tried to have pixels with full alpha values not rendered using D3DRS_ALPHATESTENABLE, D3DRS_ALPHAREF, and D3DRS_ALPHAFUNC setup but this doesn't work either. I have tried using ColorFill with alpha after retrieving the backbuffer with GetBackBuffer but this doesn't work either. (again only RGB is used) Finally I have tried creating a texture, selecting a surface, colorfilling that surface with a fully transparent alpha value, then loading that surface onto the backbuffer but only the RGB values appear to be used. I have checked the capabilities using the DXCapsViewer.exe and the D3DFMT_A8R8G8B8 backbuffer format that I am using for the backbuffer is valid so it can't be that. Has anyone gotten a transparent backbuffer in directx to work in XP?

  • C# wrapper for array of three pointers

    - by fergs
    I'm currently working on a C# wrapper to work with Dallmeier Common API light. See previous posting: http://stackoverflow.com/questions/2430089/c-wrapper-and-callbacks I've got pretty much everything 'wrapped' but I'm stuck on wrapping a callback which contains an array of three pointers & an array integers: dlm_setYUVDataCllback int(int SessionHandle, void (*callback) (long IPlayerID, unsigned char** yuvData, int* pitch, int width, int height, int64_t ts, char* extData)) Function Set callback, to receive current YUV image. Arguments SessionHandle: handle to current session. Return PlayerID (see callback). Callback - IPlayerId: id to the Player object - yuvData: array of three pointers to Y, U and V part of image The YUV format used is YUV420 planar (not packed). char *y = yuvData[0]; char *u = yuvData[1]; char *v = yuvData[2]; - pitch: array of integers for pitches for Y, U and V part of image - width: intrinsic width of image. - height - ts : timestamp of current frame - extData: additional data to frame How do I go about wrapping this in c#? Any help is much appreciated.

  • Linq: Why won't Group By work when Querying DataSets?

    - by jrcs3
    While playing with Linq Group By statements using both DataSet and Linq-to-Sql DataContext, I get different results with the following VB.NET 10 code: #If IS_DS = True Then Dim myData = VbDataUtil.getOrdersDS #Else Dim myData = VbDataUtil.GetNwDataContext #End If Dim MyList = From o In myData.Orders Join od In myData.Order_Details On o.OrderID Equals od.OrderID Join e In myData.Employees On o.EmployeeID Equals e.EmployeeID Group By FullOrder = New With { .OrderId = od.OrderID, .EmployeeName = (e.FirstName & " " & e.LastName), .ShipCountry = o.ShipCountry, .OrderDate = o.OrderDate } _ Into Amount = Sum(od.Quantity * od.UnitPrice) Where FullOrder.ShipCountry = "Venezuela" Order By FullOrder.OrderId Select FullOrder.OrderId, FullOrder.OrderDate, FullOrder.EmployeeName, Amount For Each x In MyList Console.WriteLine( String.Format( "{0}; {1:d}; {2}: {3:c}", x.OrderId, x.OrderDate, x.EmployeeName, x.Amount)) Next With Linq2SQL, the grouping works properly, however, the DataSet code doesn't group properly. Here are the functions that I call to create the DataSet and Linq-to-Sql DataContext Public Shared Function getOrdersDS() As NorthwindDS Dim ds As New NorthwindDS Dim ota As New OrdersTableAdapter ota.Fill(ds.Orders) Dim otda As New Order_DetailsTableAdapter otda.Fill(ds.Order_Details) Dim eda As New EmployeesTableAdapter eda.Fill(ds.Employees) Return ds End Function Public Shared Function GetNwDataContext() As NorthwindL2SDataContext Dim s As New My.MySettings Return New NorthwindL2SDataContext(s.NorthwindConnectionString) End Function What am I missing? If it should work, how do I make it work, if it can't work, why not (what interface isn't implemented, etc)?

  • google maps not working anymore at the drop of a hat

    - by Vordreller
    2 days ago, I was working on a project that involves google maps. The website showed the maps on the pages just fine. Now, I come back to my workstation, nothing has changed, expect for the fact that the google maps won't show up anymore. The code is identical, nobody has touched my machine since I was gone, I've checked the html, everything is perfect and still this isn't working... The Javascript console is giving no errors and the code is identical to a backup I make everytime I call it a day. 2 days ago it was working, today it isn't. I've even copied the source code, put it into an html file and tried that, but the same result. I'm at a loss here. This is my code: <script type="text/javascript"> //<![CDATA[ var map; var directionsPanel; var directions; function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("map")); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); //the route description directionsPanel = document.getElementById("route"); directions = new GDirections(map, directionsPanel); directions.load({COMMAND}); } } //]]> </script> The {COMMAND} is something that the PHP template will parse, I've checked it, the format is 100% correct and like I allready said, code now is identical to the backup, and if it worked back then, it should work now. Did google update their API overnight and did a function that I use here become deprecated? I don't know what's going on here...

  • PHP templating challenge (optimizing front-end templates)

    - by Matt
    Hey all, I'm trying to do some templating optimizations and I'm wondering if it is possible to do something like this: function table_with_lowercase($data) { $out = '<table>'; for ($i=0; $i < 3; $i++) { $out .= '<tr><td>'; $out .= strtolower($data); $out .= '</td></tr>'; } $out .= "</table>"; return $out; } NOTE: You do not know what $data is when you run this function. Results in: <table> <tr><td><?php echo strtolower($data) ?></td></tr> <tr><td><?php echo strtolower($data) ?></td></tr> <tr><td><?php echo strtolower($data) ?></td></tr> </table> General Case: Anything that can be evaluated (compiled) will be. Any time there is an unknown variable, the variable and the functions enclosing it, will be output in a string format. Here's one more example: function capitalize($str) { return ucwords(strtolower($str)); } If $str is "HI ALL" then the output is: Hi All If $str is unknown then the output is: <?php echo ucwords(strtolower($str)); ?> In this case it would be easier to just call the function (ie. <?php echo capitalize($str) ?> ), but the example before would allow you to precompile your PHP to make it more efficient

  • JSON VIEW using GROUP_CONCAT question

    - by Dan Beam
    Hey DBAs and overall smart dudes. I have a question for you. We use MySQL VIEWs to format our data as JSON when it's returned (as a BLOB), which is convenient (though not particularly nice on performance, but we already know this). But, I can't seem to get a particular query working right now (each row contains NULL when it should contain a created JSON object with the values of multiple JOINs). Here's the general idea: SELECT CONCAT( "{", "\"some_list\":[", GROUP_CONCAT( DISTINCT t1.id ), "],", "\"other_list\":[", GROUP_CONCAT( DISTINCT t2.id ), "],", "}" ) cool_json FROM table_name tn INNER JOIN ( some_table st ) ON st.some_id = tn.id LEFT JOIN ( another_table at, another_one ao, used_multiple_times t1 ) ON st.id = at.some_id AND at.different_id = ao.different_id AND ao.different_id = t1.id LEFT JOIN ( another_table2 at2, another_one2 ao2, used_multiple_times t2 ) ON st.id = at2.some_id AND at2.different_id = ao2.different_id AND ao2.different_id = t2.id GROUP BY tn.id ORDER BY tn.name Anybody know the problem here? Am I missing something I should be grouping by? It was working when I was only doing 1 LEFT JOIN & GROUP_CONCAT, but now with multiple JOINs / GROUP_CONCATs it's messing it up. When I move the GROUP_CONCATs from the "cool_json" field they work as expected, but I'd like my data formatted as JSON so I can decode it server-side or client-side in one step.

  • Hierarchical object model with property inheritance and event bubbling?

    - by Winston Fassett
    I'm writing a document-based client application and I need a DOM or WPF-like, but non-visual model that: Is a tree composed of elements Can accept an unlimited number of custom properties that get/set any CLR type, including collections. Can inherit their values from their parent Can inherit their default values from an ancestor Can be derived/calculated from other properties, ancestors, or descendants Support event bubbling / tunneling There will be a core set of properties but other plugins may add their own or even create custom documents Supports full inspection by the owning document in order to persist the tree and attributes in an XML format. I realize that's a tall order but I was really hoping there would be something out there to help me get started. Unfortunately WPF DependencyObjects are too closed, proprietary, and coupled to WPF to be of any use as a document model. My needs also have a strong resemblance to the HTML DOM but I haven't been able to find any clean DOM implementations that could be decoupled from HTML or ported to .NET. My current platform is .NET/C# but if anyone knows of anything that might be useful for inspiration or embedding, regardless of the platform, I'd love to know.

  • Modify post data with a custom MVC extension?

    - by Jaxidian
    So I'm looking into writing some custom MVC extensions and the first one I'm attempting to tackle is a FormattedTextBox to handle things such as currency, dates, and times. I have the rendering of it working perfectly, formatting it, working with strong types and everything all golden. However, the problem I'm now running into is cleaning up the formatted stuff when the page posts the data back. Take for example, a currency format. Let's use USD for these examples. When an object has a property as a decimal, the value would be 79.95. Your edit view would be something like: <%= Html.FormattedTextBox(model => Model.Person.HourlyWage, "{0:C}") %> This is all well and good for the GET request, but upon POST, the value is going to be $79.95, which when you assign to that decimal, gets unhappy very quickly and ends up shoving a 0 in there. So my question is, how do I get code working somewhere to work with that value before the MVC Framework goes and starts shoving it back into my ViewModel? I'd much rather this be done server-side than client-side. Thanks!!

  • How do I create a python module from a fortran program with f2py?

    - by Lars Hellemo
    I am trying to read some smps files with python, and found a fortran implementation, so I thought I would give f2py a shot. The problem is that I have no experience with fortran. I have successfully installed gfortran and f2py on my Linux box and ran the example on thew f2py page, but I have some trouble compiling and running the large program. There are two files, one with a file reader wrapper and one with all the logic. They seem to call each other, but when I compile and link or try f2py, I get errors that they somehow can't find each other: f95 -c FILEWR~1.F f95 -c SMPSREAD.F90 f95 -o smpsread SMPSREAD.o FILEWR~1.o FILEWR~1.o In function `file_wrapper_' FILEWR~1.F(.text+0x3d) undefined reference to `chopen_' usrlibgcci486-linux-gnu4.4.1libgfortranbegin.a(fmain.o) In function `main' (.text+0x27) undefined reference to `MAIN__' collect2 ld returned 1 exit status I also tried changing the name to FILE_WRAPPER.F but that did not help. With f2py I found out I had to include a comment to get it to accept free format, and saved this as a new file and tried: f2py -c -m smpsread smpsread.f90 I get a lot of output and warnings, but the error seems to be this one: getctype: No C-type found in "{'typespec': 'type', 'attrspec': ['allocatable'], 'typename': 'node', 'dimension': [':']}", assuming void. The fortran 90 spms reader can be found here. Any help or suggestions appreciated.

For some reason, I am getting a strange COM error (0x800A03EC) Has anyone managed to get this to work? Does anyone have suggestions as to how to troubleshoot this? I've isolated this into the minimum amount of code: using Microsoft.Office.Interop.Excel; using System.Diagnostics; namespace ExcelAutomation { public static class ExcelTests { public static void CreateWorksheet() { try { var app = new Microsoft.Office.Interop.Excel.Application(); app.Visible = true; var workBooks = app.Workbooks; var newWorkbook = app.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Worksheet existingWorksheet = (Worksheet)newWorkbook.Sheets[1]; Worksheet workSheet = (Worksheet)newWorkbook.Sheets.Add ( null, // before existingWorksheet, null, // 1, null //XlSheetType.xlWorksheet ); } catch (System.Runtime.InteropServices.COMException ex) { Trace.WriteLine(string.Format("Caught COMException. Message: \"{0}\"", ex.Message)); } } } } The output window now says: Caught COMException. Message: "Exception from HRESULT: 0x800A03EC"

  • twython search api rate limit: Header information will not be updated

    - by user2715478
    I want to handle the Search-API rate limit of 180 requests / 15 minutes. The first solution I came up with was to check the remaining requests in the header and wait 900 seconds. See the following snippet: results = search_interface.cursor(search_interface.search, q=k, lang=lang, result_type=result_mode) while True: try: tweet = next(results) if limit_reached(search_interface): sleep(900) self.writer(tweet) def limit_reached(search_interface): remaining_rate = int(search_interface.get_lastfunction_header('X-Rate-Limit-Remaining')) return remaining_rate <= 2 But it seems, that the header information are not reseted to 180 after it reached the two remaining requests. The second solution I came up with was to handle the twython exception for rate limitation and wait the remaining amount of time: results = search_interface.cursor(search_interface.search, q=k, lang=lang, result_type=result_mode) while True: try: tweet = next(results) self.writer(tweet) except TwythonError as inst: logger.error(inst.msg) wait_for_reset(search_interface) continue except StopIteration: break def wait_for_reset(search_interface): reset_timestamp = int(search_interface.get_lastfunction_header('X-Rate-Limit-Reset')) now_timestamp = datetime.now().timestamp() seconds_offset = 10 t = reset_timestamp - now_timestamp + seconds_offset logger.info('Waiting {0} seconds for Twitter rate limit reset.'.format(t)) sleep(t) But with this solution I receive this message INFO: Resetting dropped connection: api.twitter.com" and the loop will not continue with the last element of the generator. Have somebody faced the same problems? Regards.

  • How to make a WPF ComboBox editable with custom values

    - by Liam
    I would like to have a combobox that allows selection from a list of values and also allow a custom value from the typed in text. For display reasons the items are a complex type (lets say the combobox item template displays a patch of color and a flag indicating if it is a custom color). public class ColorLevel { public decimal Intensity { get; set; } public bool IsCustom { get; set; } public Color BaseColor { get; set; } public override ToString() { return string.Format("{0}", Intensity*100); } } Example items var items = new [] { new ColorLevel { Intensity = 0.9m, IsCustom = false, BaseColor = Color.Red }, new ColorLevel { Intensity = 0.7m, IsCustom = false, BaseColor = Color.Red } } XAML <ComboBox SelectedItem="{Binding Path=SelectedColorLevel}" IsEditable="true" IsTextSearchEnabled="true"> </ComboBox> So the above markup works when an item is selected from the item list. And as you type with the text search the matching items are selected. If the typed text doesn't match an item then the SelectedColorLevel is set to null. The question is at what point (and how) is it best to create a new custom item that can be set to the SelectedColorLevel when the typed text doesn't match an item. For example I would want to assign a new item to the selected value such as new ColorLevel { Intensity = decimal.Parse(textvalue), IsCustom = true } or using an appropriate converter and databinding to the Text property.

  • binding nested json object value to a form field

    - by Jack
    I am building a dynamic form to edit data in a json object. First, if something like this exists let me know. I would rather not build it but I have searched many times for a tool and have found only tree like structures that require entering quotes. I would be happy to treat all values as strings. This edit functionality is for end users so it needs to be easy an not intimidating. So far I have code that generates nested tables to represent a json object. For each value I display a form field. I would like to bind the form field to the associated nested json value. If I could store a reference to the json value I would build an array of references to each value in a json object tree. I have not found a way to do that with javascript. My last resort approach will be to traverse the table after edits are made. I would rather have dynamic updates but a single submit would be better than nothing. Any ideas? // the json in files nests only a few levels. Here is the format of a simple case, { "researcherid_id":{ "id_key":"researcherid_id", "description":"Use to retrieve bibliometric data", "url_template" :[ { "name": "Author Detail", "url": "http://www.researcherid.com/rid/${key}" } ] } } $.get('file.json',make_json_form); function make_json_form(response) { dataset = $.secureEvalJSON(response); // iterate through the object and generate form field for string values. } // Then after the form is edited I want to display the raw updated json (then I want to save it but that is for another thread) // now I iterate through the form and construct the json object // I would rather have the dataset object var updated on focus out after each edit. function show_json(form_id){ var r = {}; var el = document.getElementById(form_id); table_to_json(r,el,null); $('body').html(formattedJSON(r)); }
