• Is Lightweight Code Generation (LCG) dead?

  - by Greg Beech

  In the .NET 2.0-3.5 frameworks, LCG (aka the DynamicMethod class) was a decent way to emit lightweight methods at runtime when no class structure was needed to support them. In .NET 4.0, expression trees now support statements and blocks, and as such appear to provide sufficient functionality to build just about any functionality you could require from such a method, and can be constructed in a much easier and safer way than directly emitting CIL op-codes. (This statement is borne from today's experimentation of converting some of our most complex LCG code to use expression tree building and compilation instead.) So is there any reason why one would use LCG in any new code? Is there anything it can do that expression trees cannot? Or is it now a 'dead' piece of functionality?

• Web Service appears as website instead of developer web server

  - by stocherilac

  I recently reimaged my PC and regrabbed one of our projects from Source Safe. In our solution we have a web service that normally runs on a server, however we can build the webservice on our localhost for debugging as well. However, now whenever I grab the project from source safe it is building the webservice as a website instead of a developer web server. This is causing a variety of issue, specifically I am no longer able to specify which port I would like that webservice to use. As a result I cannot connect to our database through my local webservice. How can I change the project in my solution that controls the webservice from a website to a developer web server?

• Adding a Line Break in mySQL INSERT INTO text

  - by james

  Hi Could someone tell me how to add a new line in a text that i enter in a mySql table. I tried using the '\n in the line i entered with INSERT INTO statement but '\n is shown as it is. Actually i have created a table in Ms Access with some data. Ms Access adds new line with '\n. I am converting Ms Access table data into mySql . But when i convert, the '\n is ignored and all the text is shown in one single line when i display it from mySql table on a php form. Can anyone tell me how mySQL can add a new line in a text ? Awaiting response Thanks !!

• DisplayName attribute from Resources?

  - by Palantir

  Hello! I have a localized application, and I am wondering if it is possible to have the DisplayName for a certain model property set from a Resource. I'd like to do something like this: public class MyModel { [Required] [DisplayName(Resources.Resources.labelForName)] public string name{ get; set; } } But I can't to it, as the compiler says: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type" :( Are there any workarounds? I am outputting labels manually, but I need these for the validator output!

• 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

• XNA 2d camera with arbitrary zoom center

  - by blooop

  I have a working 2D camera in XNA with these guts: ms = Mouse.GetState(); msv = new Vector2(ms.X, ms.Y); //screenspace mouse vecor pos = new Vector2(0, 0); //camera center of view zoom_center = cursor; //I would like to be able to define the zoom center in world coords offset = new Vector2(scrnwidth / 2, scrnheight / 2); transmatrix = Matrix.CreateTranslation(-pos.X, -pos.Y, 0) * Matrix.CreateScale(scale, scale, 1) * Matrix.CreateTranslation(offset.X, offset.Y, 0); inverse = Matrix.Invert(transmatrix); cursor = Vector2.Transform(msv, inverse); //the mouse position in world coords I can move the camera position around and change the zoom level (with other code that I have not pasted here for brevity). The camera always zooms around the center of the screen, but I would like to be able to zoom about an arbitrary zoom point (the cursor in this case), like the indie game dyson http://www.youtube.com/watch?v=YiwjjCMqnpg&feature=player_detailpage#t=144s I have tried all the combinations that make sense to me, but am completely stuck.

• Spaces around all hyphens in a string without double-up

  - by Dave

  I'm after a regex that puts spaces around each "-" in a string, eg. 02 jaguar-leopard, tiger-panther 08 would become 02 jaguar - leopard, tiger - panther 08 Note that if the "-" already has spaces around it, no changes are to be made, eg. 02 jaguar - leopard, tiger - panther 08 should not become 02 jaguar - leopard, tiger - panther 08 The number of hyphens are unknown in advance. Thanks for any ideas... Edit: I'm not actually using a language for this. I'm using Ant Renamer (a mass file renaming utility). There are two fields in the renamer GUI, "Expression" and "New name" to provide inputs. This is from the help file as an example: Swapping artist and title from mp3 file names: "Expression" = (.*) - (.*)\.mp3 "New name" = $2 - $1.mp3 Extract episode number and title from series video files with episode number as SnnEmm followed by title: "Expression" = Code\.Quantum\.S([0-9]{2})E([0-9]{2})\.(.*)\.FRENCH.XViD\.avi "New name" = Code Quantum - $1$2 - $3.avi

• Displaying Fields (and/instead of Properties) in a PropertyGrid

  - by Jenk

  I'd like to use a PropertyGrid to manipulate the data on some objects, however these objects don't have properties, they have fields. Thus a property grid doesn't display them (high five MS!) Before anyone posts "just use properties": I can't at the moment.. these objects are DTOs and are used to send data to a VB6 Interop dll, thus all the parameters for the method calls are "ref" parameters (high five MS!), and C# won't compile if you use a property instead of a field or variable (high five MS!). No, I am not going to create local variables for every property on any given object. There many, many fields, and many, many test cases that would need updating, as well as the production code it self, and this post/question may be the path of least resistance. :)

• NHibernate: how to do lookup a specific date

  - by Daoming Yang

  How I can lookup a specific date in Nhibernate? I'm currently using this to lookup one day's order. ICriteria criteria = SessionManager.CurrentSession.CreateCriteria(typeof(Order)) .Add(Expression.Between("DateCreated", date.Date.AddDays(-1), date.Date.AddDays(1))) .AddOrder(NHibernate.Criterion.Order.Desc("OrderID")); I tried the following code, but they did bring the data for me. Expression.Eq("DateCreated", date) Expression.Like("DateCreated", date) Note: The pass in date value will be like this 2010-04-03 00:00:00, The actual date value in the database will be like this 2010-03-13 11:17:16.000 Can anyone let me know how to do this? Many thanks.

  public override Models.CalculationNode Parse(string expression) { var calNode = new Models.CalculationNode(); int i = expression.Length; char[] x = expression.ToCharArray(); string temp = ""; //Backwards assembly of the tree //Right Node while (!IsOperator(x[i]) && i > 0) { if (!x[i].Equals(' ')) temp = x[i] + temp; i--; } } It has been a while since I've used trees and I'm getting an out of bounds exception in the while loop.

• Formatting Field Declarations in Eclipse

  - by geeko

  Greetings Overflowers, Problem: public abstract class Filter { private long id; protected String expression; } how can I align fields automatically in Eclipse, such in: public abstract class Filter { private long id; protected String expression; } Note the space before long, thank you ! UPDATE: I cannot find a customization option to align types of class members (e.g.: long and String) under Eclipse formatter options. Yes, there is one to align names of class members (e.g.: id and expression) but not their types. Please, take a lock at this issue in my examples above. Any solution ?

• Click-Once deployment is leaving multiple versions (yes, more than 2)

  - by Clyde

  I've got a click once application that is leaving all old versions on my disk. It's an internal corporate application that gets frequent updates, so this is a disaster for rapidly inflating our backup size. According to the docs and other SO questions, it is supposed to only leave the current and previous versions on disk. However, each time I deploy the project and upgrade a client, I get another copy of all exe/dll/data files. I'm making no changes whatsoever to the application, just pushing deploy again in Visual Studio. Any ideas? Updates: The problem seems to happen on both Windows 7 and XP. 64 bit windows and 32. I've done a diff of the folders where the version is installed and the following files are different: MyApp.exe.manifest MyApp.exe.cdf-ms MyDll1.cdf-ms MyDll2.cdf-ms No actual executable files are different, nor the MyApp.manifest, MyDll1.manifest, etc.

• How do I test against a large number of regular expressions quickly and know which one matched?

  - by Jack

  I'm writing a program in .net where the user may provide a large number of regular expressions. For a given string, I need to figure out which regular expression matches that string (if more than one matches, I just need the first one that matches). However, if there are a large number of regular expressions this operation can take a very long time. I was somewhat hoping there would be something similar to flex for .net that would allow me to specify a large number of regular expressions yet quickly (O(n) according to Wikipedia for n = len(input string)) figure out which regular expression matches. Also, I would prefer not to implement my own regular expression engine :).

• Cannot bind to list<T>.property or list<T>.item.property in details section of Telerik report

  - by fluf

  I have created a Telerik report and I am setting the datasource on runtime to an object with some properties and a List. I am using the properties in the page and report header sections and i want to use the list as the details. Now the problem is binding to the List's item properties in the details section. I have played around with the expression builder and it seems that i should access the properties like this : [=Fields.myList.Item.myProperty] when i run the program i get a nice big red rectangle with the following error : An error has occured while processing TextBox 'textBox28':Common Language Runtime detected an invalid program. I have tried to change different variants of expression which also gives me other errors [=Fields.myList.myPropery] An error has occured while processing TextBox 'textBox28': The expression contains object 'myProperty' that is not defined in the current context. The closest i have gotton was with the object it self, which outputs the object.toString() [=Fields.myList]

• Regex to match a Java method signature

  - by nitesh

  I am having this particular requirement where a method has to be identified by different regular expressions for different components. For example, there need to be a regex for return parameter, one for method name, one for argument type and one for argument name. I was able to come up with an expression till this step as follows - ([^,]+) ([^,]+)\((([^,]+) ([^,]+))\) It works well for a method signature like - ReturnType foo(Arg parameter) The regular expression identifies ReturnType, foo, Arg and parameter separately. Now the problem is that a method can have no/one/multiple arguments separated by commas. I am not able to get a repeating expression for this. Help will be appreciated.

• Overloading assignment operator in C#

  - by Carson Myers

  I know the = operator can't be overloaded, but there must be a way to do what I want here: I'm just creating classes to represent quantitative units, since I'm doing a bit of physics. Apparently I can't just inherit from a primitive, but I want my classes to behave exactly like primitives -- I just want them typed differently. So I'd be able to go, Velocity ms = 0; ms = 17.4; ms += 9.8; etc. I'm not sure how to do this. I figured I'd just write some classes like so: class Power { private Double Value { get; set; } //operator overloads for +, -, /, *, =, etc } But apparently I can't overload the assignment operator. Is there any way I can get this behavior?

• How do I make a URL text a link?

  - by jpjp

  Say on Facebook or Twitter, when I type "www.google.com" and submit it, it becomes a link. How do I code this in PHP? Do I use regular expressions to get where the www starts and the .com ends? Is this how they do it? <?PHP //some regular expression to get www and .com part $link="<a href='$url'>$url</a>"; echo $link; ?> How do I write a regular expression to get the "www" and ".com" part? And for twitter's @obama, obama would become a link to obama's site. What regular expression do they use to get the text after the @ and before the space?

• Game network physics collision

  - by Jonas Byström

  How to simulating two client-controlled vehicles colliding (sensibly) in a typical client/server setup for a network game? I did read this eminent blog post on how to do distributed network physics in general (without traditional client prediction), but this question is specifically on how to handle collisions of owned objects. Example Say client A is 20 ms ahead of server, client B 300 ms ahead of server (counting both latency and maximum jitter). This means that when the two vehicles collide, both clients will see the other as 320 ms behind - in the opposite direction of the velocity of the other vehicle. Head-to-head on a Swedish highway means a difference of 16 meters/17.5 yards! What not to try It is virtually impossible to extrapolate the positions, since I also have very complex vehicles with joints and bodies all over, which in turn have linear and angular positions, velocities and accelerations, not to mention states from user input.

• Secrets of delivering .NET size large products?

  - by Joan Venge

  In software companies I have seen it's really hard to work on very large products where everything depends on everything else. For instance Microsoft works on C#, F#, .NET, WPF, Visual Studio where these things are interconnected. I don't know how many people are involved, but if it's in 100s, how do they keep in sync with everything, so they design and implement features without conflicting with other dependencies and future plans of other products? I am wondering that if MS is able to do this, they must have a very good system. Any guidelines or secrets for MS or non-MS very large software product delivering?

• Using preg_match as boolean AND array

  - by silow

  I have this code where preg_match is used to break up a string into $pmarr array. Index 1 of that array is then being used to set a value $val = $pmarr[1]. $pmarr = array(); if (preg_match($expression, $orig, $pmarr)) { $val = $pmarr[1]; } What I'm wondering about is why the preg_match itself is being used as a boolean. If the expression doesn't match, does the array stay empty and therefore equate to false? Is the above code the same as saying preg_match($expression, $orig, $pmarr); if(isset($pmarr[1]) AND !empty($pmarr[1])){ $val = $pmarr[1]; }
