  • How to restrict special symbols like % in textbox in wpf?

    - by Vamsy
    I would like to develop a textbox which restricts special symbols like %. I used textbox's keydown event to restrict '%' . I already used the code as if(Keyboard.Modifiers == ModifierKeys.Shift && e.key == key.D5) { e.handle=true; return; } when i implement this in mvvm architecture, I got problem with the dependency property that recognizes only shift as one key and D5 as another when I converted systemkey into string format. How can I recognize % symbol?

  • Getting Http Status code number (200, 301, 404, etc.) from HttpWebRequest and HttpWebResponse

    - by James Lawruk
    I am trying to get the HTTP status code number from the HttpWebResponse object returned from a HttpWebRequest. I was hoping to get the actual numbers (200, 301,302, 404, etc.) rather than the text description. ("Ok", "MovedPermanently", etc.) Is the number buried in a property somewhere in the response object? Any ideas other than creating a big switch function? Thanks. HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://www.gooogle.com/"); webRequest.AllowAutoRedirect = false; HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse(); //Returns "MovedPermanently", not 301 which is what I want. Console.Write(response.StatusCode.ToString());

  • packing fields of a class into a byte array in c#

    - by alex
    Hi all: I am trying to create a fast way to convert c# classes into byte array. I thought of serializing the class directly to a byte array using an example I found: // Convert an object to a byte array private byte[] ObjectToByteArray(Object obj) { if(obj == null) return null; BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); bf.Serialize(ms, obj); return ms.ToArray(); } But the byte array I got contains some other information that are not related to the fields in the class. I guess it is also converting the Properties of the class. Is there a way to serialize only the fields of the class to a byte array? Thanks

  • Help me understand Dispose() implementation code from MSDN

    - by Benny
    the following code is from MSDN: Idisposable pattern protected virtual void Dispose(bool disposing) { // If you need thread safety, use a lock around these // operations, as well as in your methods that use the resource. if (!_disposed) { if (disposing) { if (_resource != null) _resource.Dispose(); Console.WriteLine("Object disposed."); } // Indicate that the instance has been disposed. _resource = null; _disposed = true; } } why the following statement: _resource = null; _disposed = true; are not enclosed by if (disposing) statement block? for me i would probably write like this: if (disposing) { if (_resource != null) { _resource.Dispose(); _resource = null; _disposed = true; } Console.WriteLine("Object disposed."); } anything wrong with my version?

  • Do we really need a safe release macro?

    - by Ian1971
    Quite a lot of people seem to use a macro such as #define SAFE_RELEASE(X) [X release]; X = nil; (myself included). I've been reassessing why I am using it and wanted to canvas some opinion. The purpose (I think) for using this macro is so that if you were to accidentally use your object after releasing it then you won't get a bad access exception because objective-c will quite happily ignore it when the object is nil. It strikes me that this has the potential to mask some obscure bugs. Maybe it would actually be preferable for the program to crash when you try to use X again. That way during testing you can find the issue and improve the code. Does this macro encourage lazy programming? Thoughts?

  • Grails unit testing domain classes with Set properties - is this safe?

    - by Ali G
    I've created a domain class in Grails like this: class MyObject { static hasMany = [tags: String] // Have to declare this here, as nullable constraint does not seem to be honoured Set tags = new HashSet() static constraints = { tags(nullable: false) } } Writing unit tests to check the size and content of the MyObject.tags property, I found I had to do the following: assertLength(x, myObject.tags as Object[]) assertEquals(new HashSet([...]), myObject.tags) To make the syntax nicer for writing the tests, I implemented the following methods: void assertEquals(List expected, Set actual) { assertEquals(new HashSet(expected), actual) } void assertLength(int expected, Set set) { assertLength(expected, set as Object[]) } I can now call the assertLength() and assertEquals() methods directly on an instance of Set, e.g. assertLength(x, myObject.tags) assertEquals([...], myObject.tags) I'm new to Groovy and Grails, so unaware how dangerous method overloading like this is. Is it safe? If so, I'm slightly* surprised that these methods (or similar) aren't already available - please let me know if they are. * I can see how these methods could also introduce ambiguity if people weren't expecting them. E.g. assertLength(1, set) always passes, no matter what the content of set

  • NetBeans Platform Unit Test Library Dependencies

    - by Ben Hammond
    I am working on a Netbeans Platform RCP application. I use jmock in my unit tests and I have created a Library Wrapper Module to import the necessary libraries. The Module has an section named 'Libraries' and another section named 'Unit Test Libraries'. I hoped that I could add the JMock Library Wrapper to the 'Unit Test Libraries', however when I run the unit tests I get the error 'package org.jmock does not exist'. If I import the JMock Library Wrapper in to the main 'Libraries' element then it works, but this feels wrong. Maven allows me to specify unit-test only dependencies, and I assumed that NetBeans Platform did the same. Should this be possible? Am I doing something wrong? Should I resign myself to a run-time dependency on the unit-test libraries (ugh).

  • How to run lengthy tasks from an ASP.NET page?

    - by Jimmy C
    I've got an ASP.NET page with a simple form. The user fills out the form with some details, uploads a document, and some processing of the file then needs to happens on the server side. My question is - what's the best approach to handling the server side processing of the files? The processing involves calling an exe. Should I use seperate threads for this? Ideally I want the user to submit the form without the web page just hanging there while the processing takes place. I've tried this code but my task never runs on the server: Action<object> action = (object obj) => { // Create a .xdu file for this job string xduFile = launcher.CreateSingleJobBatchFile(LanguagePair, SourceFileLocation); // Launch the job launcher.ProcessJob(xduFile); }; Task job = new Task(action, "test"); job.Start(); Any suggestions are appreciated.

  • Why does this VBS scheduled task (to call a URL) not work in Windows Server 2008?

    - by user303644
    This same script worked in older server OS environments, and even on my desktop; and allows me to kick off a nightly process on my website's URL. It simply will not execute the URL in my Windows Server 2008 environment. It does not generate any errors, claiming task completion I can pull the same URL up just fine in the server's web browser I have the script running with "highest privileges" I even tried to create a batch file which executes it, so I can explicitly "Run as Administrator" and it still will not execute the URL (but will not generate any errors either). I'm baffled as to why the task claims to have completed successfully, yet the script never reaches the URL. Call LogEntry() Sub LogEntry() 'Force the script to finish on an error. On Error Resume Next 'Declare variables Dim objRequest Dim URL Set objRequest = CreateObject("MSXML2.ServerXMLHTTP") 'Put together the URL link appending the Variables. URL = "http://myURL/AutorunNightlyTasks.aspx" 'Open the HTTP request and pass the URL to the objRequest object objRequest.open "GET", URL, False 'Send the HTML Request objRequest.send() 'Set the object to nothing Set objRequest = Nothing End Sub

  • Mono 2.10.5 Runtime error on Ubuntu 11.10

    - by johnluetke
    I've install mono-runtime via apt in order to run my Mono console application on Ubuntu via SSH. However, when I run the command mono myapp.exe, It exits, with no message, and my program does nothing. If I throw the -v switch to Mono, such as mono -v myapp.exe, I get about 10k lines of output (as expected, -v is verbose), with the first few lines being: converting method System.OutOfMemoryException:.ctor (string) Method System.OutOfMemoryException:.ctor (string) emitted at 0xb7052c28 to 0xb7052c4b (code length 35) [myapp.exe] converting method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) Method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) emitted at 0xb7052c68 to 0xb7052cf6 (code length 142) [myapp.exe] converting method System.SystemException:.ctor (string) I read this as the runtime throwing an OutOfMemory exception, but the machine is under no intense load, has plenty of available RAM, and is running nothing other that system processes. I've removed and reinstalled Mono countless times, and have even run the executable on other machines perfectly fine. Am I missing something completely obvious here?

  • HQL - row identifier for pagination

    - by anna.ruk
    Does anyone know if HQL has a keyword to identify rows such as ROWID or ROWNUM? I would like to implement pagination with HQL but I am not able to use .setMaxResult() or .setFirstResult() because I don't work with the session object directly and therefore don't use the Query object but simply create my query as a string and use the .find() method. I tried using LIMIT and OFFSET in my query, but HQL seems to be ignoring these keywords and is returning the whole result to me no matter what. I'm also not able to use Hibernate criteria because it does not have support for the "HAVING" clause that appears in my query. My last resort is to restrict the result set using the ROWNUM/ROWID keyword. Does anyone else have any other suggestions?

  • Visual Studio: Link executable

    - by smerlin
    Lets say I have: a static library project called "LIB" a application project called "LIBAPP" a application project called "APP" a application project called "APPTEST" When i add "LIB" to LIBAPP Project Dependencies, Visual Studio automatically links "LIBAPP" against LIB. But when i add APP to APPTEST Project Dependencies, it doesnt. Since i am doing unit tests of APP's classes in APPTEST, i have to link against APP, therefore i am currently manually linking against all *.obj files of APP (hundreds...) Since i have to change the link targets of APPTEST everytime i add or remove a *.cpp file from APP, this isnt a nice solution. So is there a way to force Visual Studio to do this for me automatically, like it does when adding a static library Project Dependency ?

  • Relative Dates with Datejs

    - by Prasanna
    I have a requirement where in, I have to parse the dates relative to a date object returned from the server side. But the datejs library always considers only the browsers date object. The situation is something like this: The server gives back the date in PST and the browser is in IST. And all the inputs are getting parsed with respect to the current date in IST instead of current date in PST. Is there any way I could resolve this. Or could you suggest any workarounds. Thanks in advance.

  • HD Crash SQL server -> DBCC - consistency errors in table 'sysindexes'

    - by Julian de Wit
    Hello A client of mine has had an HD crash an a SQL DB got corrupt : They did not make backups so they have a big problem. When I tried (an ultimate measure) to DBCC-repair I got the following message. Can anybody help me with this ? Server: Msg 8966, Level 16, State 1, Line 1 Could not read and latch page (1:872) with latch type SH. sysindexes failed. Server: Msg 8944, Level 16, State 1, Line 1 Table error: Object ID 2, index ID 0, page (1:872), row 11. Test (columnOffsets->IsComplex (varColumnNumber) && (ColumnId == COLID_HYDRA_TEXTPTR || ColumnId == COLID_INROW_ROOT || ColumnId == COLID_BACKPTR)) failed. Values are 2 and 5. The repair level on the DBCC statement caused this repair to be bypassed. CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'sysindexes' (object ID 2). DBCC execution completed. If DBCC printed error messages, contact your system administrator.

  • Merge two lists of objects which hold different data

    - by C.McAtackney
    I have an object "Project" which has a number of fields, one of which is "Name". I have one spreadsheet of projects which contains some of these fields, and another which contains the rest. However, Both spreadsheets have the "Name" field. I've read them in and populated two List, only populating the available fields from that particular source. E.g. a Project from List 1 looks like; {Name="MyProj", Type="Form", Priority=NULL}, whereas a Project from List 2 {Name="MyProj", Type=NULL, Priority="High"}. Now, I want to merge these two lists into one in which each Project object has all of its fields populated, with the Name field being used to match the elements. How can I achieve this? Are there any nice ways of doing this concisely? Thanks

  • relating data stored in NoSQL DB to data stored in SQL DB

    - by seanbrant
    Whats the best way to use a SQL DB along side a NoSQL DB? I want to keep my users and other data in postgres but have some data that would be better suited for a NoSQL DB like redis. I see a lot of talk about switching to NoSQL but little talk on integrating it with existing systems. I think it would be foolish to throw the baby out with the bath water and ditch SQL all together, unless it makes things easier to maintain and develop. I'm wondering what the best approach is for relating data stored in SQL to my data in redis. I was thinking of something along the line of this. User object stored in SQL Book object in redis, key sh1 hash of value, value is a JSON string Relations stored in redis, key User.pk:books, value redis set of sha1's Anyone have experience, tips, better ways?

  • How can I create a generic constructor? (ie. BaseClass.FromXml(<param>)

    - by SofaKng
    I'm not sure how to describe this but I'm trying to create a base class that contains a shared (factory) function called FromXml. I want this function to instantiate an object of the proper type and then fill it via an XmlDocument. For example, let's say I have something like this: Public Class XmlObject Public Shared Function FromXml(ByVal source as XmlDocument) As XmlObject // <need code to create SPECIFIC TYPE of object and return it End Function End Class Public Class CustomObject Inherits XmlObject End Class I'd like to be able to do something like this: Dim myObject As CustomObject = CustomObject.FromXml(source) Is this possible?

  • How do I render a partial to a string from within a filter attached to a controller

    - by Tristan Havelick
    I have some code I need to use in multiple controllers in a rails 1.0 application (I can't, for strange reasons upgrade to a newer rails). I've extracted the relevant code into a filer object, and I'm using the around_filter construct to execute it. Before the extract, I was using the method render_to_string() to get the contents of a rendered partial into a string. However, this method is protected, so I am unable to access it from within my Filter object. As a workaround, I tried adding this to my ApplicationController: def render_to_string(*a) super(*a) end this seems to have remedied the protection level issue, but now I get the error: Can only render or redirect once per action When no such error occurred before the extraction. Why? Is there a different approach I should take here?

  • Weird exception with delayed_job

  • Changing Pushpin Text Color

    - by Yawus
    I'm attempting to display data through the text of a Pushpin object. However, the text color defaults to white which is nigh-invisible when the backdrop is a road-style MapView. Looking through the API, paying especially close attention to PushpinOptions, I couldn't find anything that manipulated text color. Considering that this seems to a fairly basic feature, I'm a little confused as to why it doesn't exist or at least is really hard to find. Am I missing something or does Bing Maps for Android really not let you change the default text color for a Pushpin object?

  • Mocking my custom dependencies with Spring

    - by Brabster
    Is is possible to declare mocks using some mocking framework for my own classes declaratively with Spring? I know there are some standard mocks available in Spring, but I'd like to be able to mock out my own classes declaratively too. Just to check I'm not going about this the wrong way: the idea is to have a pair of JUnit test and Spring config for each integration test I want to do, mocking everything except the specific integration aspect I'm testing (say I had a dependency on two different data services, test one at a time) and minimising the amount of repeated Java code specifying the mocks.

  • Casting objects in C# (ASP.Net MVC)

    - by Mortanis
    I'm coming from a background in ColdFusion, and finally moving onto something modern, so please bear with me. I'm running into a problem casting objects. I have two database tables that I'm using as Models - Residential and Commercial. Both of them share the majority of their fields, though each has a few unique fields. I've created another class as a container that contains the sum of all property fields. Query the Residential and Commercial, stuff it into my container, cunningly called Property. This works fine. However, I'm having problems aliasing the fields from Residential/Commercial onto Property. It's quite easy to create a method for each property: fillPropertyByResidential(Residential source) and fillPropertyByCommercial(Commercial source), and alias the variables. That also works fine, but quite obviously will copy a bunch of code - all those fields that are shared between the two main Models. So, I'd like a generic fillPropertyBySource() that takes the object, and detects if it's Residential or Commercial, fills the particular fields of each respective type, then do all the fields in common. Except, I gather in C# that variables created inside an If are only in the scope of the if, so I'm not sure how to do this. public property fillPropertyBySource(object source) { property prop = new property(); if (source is Residential) { Residential o = (Residential)source; //Fill Residential only fields } else if (source is Commercial) { Commercial o = (Commercial)source; //Fill Commercial only fields } //Fill fields shared by both prop.price = (int)o.price; prop.bathrooms = (float)o.bathrooms; return prop; } "o" being a Commercial or Residential only exists within the scope of the if. How do I detect the original type of the source object and take action? Bear with me - the shift from ColdFusion into a modern language is pretty..... difficult. More so since I'm used to procedural code and MVC is a massive paradigm shift. Edit: I should include the error: The name 'o' does not exist in the current context For the aliases of price and bathrooms in the shared area.
