  • Visual Studio - easy way to bring up type definition as source code

    - by Igor Zevaka
    Oftentimes I want to bring up a system class in a source view, so that I can browse the properties and methods exposed by the class in a source view. Below is the screenshot of what I mean: Usually I do this by selecting the class name and pressing F12 (or right clickGo To Definition). However, if I haven't got it anywhere ready, i have type it up and then do Go To Definition. Most of the time I have to delete what I typed later on. Is there a way to bring up this view without having to type the class name? The VS2010 Navigate To dialog doesn't support this.

  • Windows equivalent to this Makefile

    - by Sridhar Ratnakumar
    The advantage of writing a Makefile is that "make" is generally assumed to be present on the various Unices (Linux and Mac primarily). Now I have the following Makefile: PYTHON := python all: e installdeps e: virtualenv --distribute --python=${PYTHON} e installdeps: e/bin/python setup.py develop clean: rm -rf e As you can see this Makefile uses simple targets and variable substitution. Can this be achieved on Windows? By that mean - without having to install external tools (like cygwin make); perhaps make.cmd? Typing "make installdeps" for instance, should work both on Unix and Windows.

  • Is it possible to set ContentType for a WCF WebGet method?

    - by James Cadd
    I'm working with a WCF restful/http method that returns a stream of image data. I want to make sure that the content type is marked as "image/png". The method is defined as: [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] public class TileImageService { [WebGet(UriTemplate = "{id}")] public Stream GetTileImage(string id) { Bitmap bmp = new Bitmap(173, 173); Graphics g = Graphics.FromImage(bmp); g.Clear(Color.Blue); g.DrawString(DateTime.Now.ToLongTimeString(), new Font("Chiller", 20), Brushes.White, new PointF(10, 10)); g.Flush(); MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Png); ms.Seek(0, SeekOrigin.Begin); return ms; } } In Firefox it looks like the content type is marked as application/octet stream. Is there a way to change the content type?

  • Unknown attribute xsi:type in XmlSerializer

    - by vanccoon
    I am learning XML Serialization and meet an issue, I have two claess [System.Xml.Serialization.XmlInclude(typeof(SubClass))] public class BaseClass { } public class SubClass : BaseClass { } I am trying to serialize a SubClass object into XML file, I use blow code XmlSerializer xs = new XmlSerializer(typeof(Base)); xs.Serialize(fs, SubClassObject); I noticed Serialization succeed, but the XML file is kind of like ... If I use XmlSerializer xs = new XmlSerializer(typeof(Base)); SubClassObject = xs.Deserialize(fs) as SubClass; I noticed it will complain xsi:type is unknown attribute(I registered an event), although all information embedded in the XML was parsed successfully and members in SubClassObject was restored correctly. Anyone has any idea why there is error in parsing xsi:type and anything I did wrong? Thanks

  • Is it bad practice to use an enum that maps to some seed data in a Database?

    - by skb
    I have a table in my database called "OrderItemType" which has about 5 records for the different OrderItemTypes in my system. Each OrderItem contains an OrderItemType, and this gives me referential integrity. In my middletier code, I also have an enum which matches the values in this table so that I can have business logic for the different types. My dev manager says he hates it when people do this, and I am not exactly sure why. Is there a better practice I should be following?

  • C# equivalent of NaN or IsNumeric

    - by johnc
    This seems like a fairly simple question, and I'm surprised not to have required it before. What is the most efficient way of testing a string input is a numeric (or conversely Not A Number). I guess I can do a Double.Parse or a regex (see below) public static bool IsNumeric(this string value) { return Regex.IsMatch(value, "^\\d+$"); } but I was wondering if there was a implemented way to do it, such as javascript's NaN() or IsNumeric() (was that VB, I can't remember).

  • saving a records containing a member of type string to a file (Delphi, Windows)

    - by wonderer
    I have a record that looks similar to: type TNote = record Title : string; Note : string; Index : integer; end; Simple. The reason I chose to set the variables as string (as opposed to an array of chars) is that I have no idea how long those strings are going to be. They can be 1 char long, 200 or 2000. Of course when I try to save the record to a type file (file of...) the compiler complains that I have to give a size to string. Is there a way to overcome this? or a way to save those records to an untyped file and still maintain a sort of searchable way? Please do not point me to possible solutions, if you know the solution please post code. Thank you

  • Constructor type not found

    - by WaffleTop
    Hello, What I am doing: I am taking the Microsoft Enterprise Library 4.1 and attempting to expand upon it using a few derived classes. I have created a MyLogEntry, MyFormatter, and MyTraceListener which derive from their respective base classes when you remove the "My" from their names. What my problem is: Everything compiles fine. When I go to run a test using Logger.Write(logEntry) it errors right after it initializes MyTraceListener with an error message: "The current build operation (... EnterpriseLibrary.Logging.LogWriter, null]) failed: Constructor on type 'MyLogging.MyFormatter' not found. (Strategy type ConfiguredObjectStrategy, index 2) I figured it was something to do with the constructor so I tried removing it, add it, and adding a call to the base class LogFormatter. Nothing has worked. Does anyone have insight into this problem? Is it maybe a reference issue? Bad App.config configuration? Thank you in advance

  • VB.NET template instance - passing a variable data type

    - by FerretallicA
    As the title suggests, I'm tyring to pass a variable data type to a template class. Something like this: frmExample = New LookupForm(Of Models.MyClass) 'Works fine Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine repoGeneric = New Repositories.Repository(Of SelectedType) 'Ba-bow! repoGeneric = New Repositories.Repository(Of InstanceOfMyClass.GetType()) 'Ba-bow! I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either. (How) can I create an instance of a dynamically typed repository at runtime?

  • Is there an equivalent for ActiveRecord#find_by equivalent for C#?

    - by Benjamin Manns
    I'm originally a C# developer (as a hobby), but as of late I have been digging into Ruby on Rails and I am really enjoying it. Right now I am building an application in C# and I was wondering if there is any collection implementation for C# that could match (or "semi-match") the find_by method of ActiveRecord. What I am essentially looking for is a list that would hold Rectangles: class Rectangle { public int Width { get; set; } public int Height { get; set; } public String Name { get; set; } } Where I could query this list and find all entries with Height = 10, Width = 20, or name = "Block". This was done with ActiveRecord by doing a call similar to Rectangle.find_by_name('Block'). The only way I can think of doing this in C# is to create my own list implementation and iterate through each item manually checking each item against the criteria. I fear I would be reinventing the wheel (and one of poorer quality). Any input or suggestions is much appreciated.

  • Equivalent of Switch Statement in MySql 5

    - by Robert Gowland
    Using MySql 5, I have a task where I need to update one table based on the contents of another table. For example, I need to add 'A1' to table 'A' if table 'B' contains 'B1'. I need to add 'A2a' and 'A2b' to table 'A' if table 'B' contains 'B2', etc.. In our case, the value in table 'B' we're interested is an enum. Right now I have a stored procedure containing a series of statements like: INSERT INTO A SELECT 'A1' FROM B WHERE B.Value = 'B1'; --Repeat for 'B2' -> 'A2a', 'A2b'; 'B3' -> 'A3', etc... Is there a nicer more DRY way of accomplishing this?

  • threading.local equivalent for twisted.web?

    - by defnull
    In asynchronous environments, threading.local is not guaranteed to be context-local anymore, because several contexts may coexist within a single thread. Most asynchronous frameworks (gevent, eventlet) provide a get_current_context() functionality to identify the current context. Some offer a way to monkey-patch threading.local so it is local to 'greenthreads' or other framework-specific contexts. I cannot find such a functionality in the twisted documentation. How do I do this?

  • What is the equivalent of REGEXP_SUBSTR in mysql?

    - by KandadaBoggu
    I want to extract a word from a string column of a table. description =========================== abc order_id: 2 xxxx yyy aa mmm order_id: 3 nn kk yw Expected result set order_id =========================== 2 3 Table will at most have 100 rows, text length is ~256 char and column always has one order_id present. So performance is not an issue. In Oracle, I can use REGEXP_SUBSTR for this problem. How would I solve this in MySQL?

  • How to change a variable type in C#?

    - by Mosho Mulan
    I wanted to use something like this: if(x==5) { var mydb= ........ ; } else { var mydb = ........ ; } but it didn't work because I can't declare a variable inside if statement. So I tried to do this: var mydb; if (x==5) { mydb= ............. ; } else { mydb=.............; } but id didn't work either because I had to initialize the variable (mydb). So the question is: I don't necessarily know the type of the variable, can I declare it anyway and then change the type inside the if statement?

  • Select...Case VB.NET to C# Equivalent

    - by Alex Essilfie
    I just started using C# and I've got a couple of issues. I hook several controls to one event handler as in the following and I want to perform a slightly different action for each control: Private Sub Button_Click(sender as Object, e as EventArgs) _ Handles button1.Click, Button2.Click 'do a general activity Select CType(sender, Button).Name Case button1.Name 'do something Case button2.Name 'do something else Case Else 'do the defalut action End Select End Sub Is there any way of doing the above select statement in C# without having to use nested ifs?

  • Mercurial merge strategy per file type

    - by dls
    All: I want to use kdiff to merge all files with a certain suffix (say *.c, *.h) and I want to do two things (turn off premerge and use internal:other) for all files with another suffix (say *.mdl). The purpose of this is to allow me to employ a type of 'clobber merge' for a specific file type (ie: un-mergable files like configurations, auto-generated C, models, etc..) In my .hgrc I've tried: [merge-tools] kdiff3= clobbermerge=internal:other clobbermerge.premerge = False [merge-patterns] **.c = kdiff3 **.h = kdiff3 **.mdl = clobbermerge but it still triggers kdiff3 for all files. Thoughts? An extension of this would be to perform a 'clobber merge' on a directory - but once the syntax is clear for a file suffix, the dir should be easy.

  • Type mismatch: cannot convert from ArrayList<Data> to MyCollection

    - by Tommy
    I've read similar questions here but I'm still a little confused. MyCollection extends ArrayList<MyClass> MyClass implements Data yet this gives me the "cannot convert from ArrayList to MyCollection" MyCollection mycollection = somehandler.getCollection(); where getCollection looks like this public ArrayList<Data> getCollection() So my assumptions are obviously wrong. How can I make this work like I would like it to

  • How to know file type without extension

    - by Ayusman
    While trying to come-up with a servlet based application to read files and manipulate them (image type conversion) here is a question that came up to me: Is it possible to inspect a file content and know the filetype? Is there a standard that specifies that each file MUST provide some type of marker in their content so that the application will not have to rely on the file extension constraints? Consider an application scenario: I am creating an application that will be able to convert different file formats to a set of output formats. Say user uploads an PDF, my application can suggest that the possible conversion formats are microsoft word or TIFF or JPEG etc. As my application will gradually support different file formats (over a period of time), I want my application to inspect the input file instead of having the user to specify the format. And suggest to user the possible formats of output. I understand this is an open ended, broad question. Please let me know if it needs to be modified. Thanks, Ayusman

  • jquery equivalent for css3 transition ease-in

Thank you very much!

  • What are alternatives to standard ORM in a data access layer?

    - by swampsjohn
    We're all familiar with basic ORM with relational databases: an object corresponds to a row and an attribute in that object to a column (or some slight variation), though many ORMs add a lot of bells and whistles. I'm wondering what other alternatives there are (besides raw access to the database or whatever you're working with). Alternatives that just work with relational databases would be great, but ones that could encapsulate multiple types of backends besides just SQL (such as flat files, RSS, NoSQL, etc.) would be even better. I'm more interested in ideas rather than specific implantations and what languages/platforms they work with, but please link to anything you think is interesting.
