C# - Refactor Data Contracts In WCF Services?
Feb 11, 2010We have lots of WCF services that are only used by our own code; the code that uses them is mostly in the same solutions files that contains the services.
However they do not use a shared assembly for the contracts, so each time a data contract is change the reference to the service has to be updated by hand in all projects that use the service. (Then the code needs to be fixed up by hand)
So how do I do a simple refactoring like renamed a data item in a data contract?
Is there a way to update all references to services in a single solution with one command, rather then having to click on each reference in each project?
Prevent Data Layer Refactoring Of ODP.NET Code And Transactions?
Aug 27, 2009I am using Oracle 11g client, with ODP.NET. I am trying to add conditional Transaction handling.
Dim ds As New DataSet()
Dim txn As OracleTransaction
Dim _beginTransaction as Bolean = true
Using conn As New OracleConnection(ConnString)
[Code]...
How do I fix txn being nothing / null? The error is: Variable 'txn' is used before it has been assigned a value. A null reference exception could result at runtime. Edit: to RichardOD for pointing out that you can not explicitly declare that a transaction cannot be opend up on stored procedures via ODP.NET. I have verified that this is an issue. BUT We still haven't figured out why the error is occuring. I understand that txn is initially given a value w/in an if statement, but being defined outside of the try/catch block should make that irrelevant.... right? Or is that bad coding?

View 3 Replies.net - C# - Code Contracts - Detected Expression Statement Evaluated For Potential Side-effect?
Jan 20, 2012I have a class with a static list of keys, and I have a static method called Remove() that removes a key from that list.Now what I understand from the contracts post conditions is that as the programmer of the class, I guarantee that the current public method does something specific, in this case : removing the element of the list.
Here's what I've written:
private static List<Keys> m_usedKeys; // private list of keys
public static void Remove(Keys _key)
{
[code]....
What I'm trying to "Ensure" here, is that the Remove() method removes the key for real from the list (Yes this might be a trivial example, but I get the error there.)when I write the Contract.Ensures() line, VS2010 gives me the following error :
Error 3 Detected expression statement evaluated for potential side-effect in contracts of method 'LibJungleTimer.KeyBind.Remove(System.Windows.Forms.Keys)'. (Did you mean to put the expression into a Requires, Ensures, or Invariant call?) C:UsersJoelDocumentsProgrammationJTJungleTimerLibJungleTimerKeyBind.cs 51
I think this error says that the expression m_usedKeys.remove(_key); has a potential side-effect. In fact, it has a side-effect, it removes a key from the list!If I try to write something like this instead :
Contract.Assert(!m_usedKeys.Any(x => x == _key));
well it compiles fine.
IDE :: Refactoring Does Not Work (enough) In VB
Sep 28, 2009I use VS 2005 and VB.NET. I have a class A. This class A is an empty class(no functions, no members). I wrote the following code: Dim _a as new A(); Dim code as String = _a.GetCode() In the same situation, the C# refactoring tool in VS 2005 IDE propose me to create a method in the A class internal string GetCode(){ }
The VB.NET compiles does not propose anything. There is a way to implement the functions when I need it in code, or I need to planify all my methods before using the class?
.net - Refactoring A Field Into A Property?
Jun 7, 2012I am currently learning vb.net for my new job and I have mixed feelings over public fields. I see many arguments about them hurting the encapsulation. In python, the common practice is to keep things simple and use fields when they are enough. If we want to add logic later, we just refactor them into a property without breaking anything for the client code.In the codebase I am working with I see huge classes containing dozen of properties like:

How To Approach Refactoring A Class
Jul 24, 2009I recently started a project and needed to do some integration with LDAP via DirectoryServices. I've done this in other apps so I went into one of them to see how I did it -- why reinvent the wheel right? Well, while this wheel works, it was developed years ago and kinda smells (it's wooden, firmly attached to the previous vehicle, hard to repair and produces a potentially bumpy ride).So I thought to myself, this is the perfect time to refactor this puppy and make it more portable, reusable, reliable, easier to configure etc. Now that's fine and dandy, but then I started feeling a tad overwhelmed regarding to where to start. Should it be a separate library? How should it be configured? Should it use IoC? DI?
So my [admittedly subjective] question is this -- given a relatively small, but quite useful class like the one below, what is a good approach to refactoring it? What questions do you ask and how do you decide what to implement or not implement? Where do you draw the line regarding configuration flexibility? [Note: Please don't bash this code too much okay? It was written a long time ago and has functioned perfectly well baked into an in house application.]

.net - Refactoring Inheritance To Composition Using Vbex2005?
Jul 7, 2010I have a class that I wrote fairly early on in my vb.net programming experience which inherited from another class it really should have composed. The base class is a relatively generic nested dictionary-based collection; let's call the descendant class a "Car".Right now there's a lot of code that does things like 'MyCar!Color.st = "Red"' (I use the generic collection rather than real properties to facilitate data interchange with code written in VB6, and also to facilitate comparisons of cars; given three cars X, Y, Z, I can e.g. detect any changes between X and Y and apply those changes to Z).
Is there any nice way to refactor the code to use composition rather than inheritance?Which properties methods should the "Car" object wrap, and which ones should be accessed through a data-object property? Should a widening conversion be defined between a car and the collection object? Are there any gotchas when doing such refactoring?

VS 2008 - Refactoring Presentation Layer
Sep 10, 2010I've been working to refactor my code and ended up with a quite clean main BLL class that has only a few manager classes that pass information between eachother. They handle separate tasks/areas like socket connection, data, etc. It's only one instance of each of these manager objects, so I believe maybe the base layout is a structural singleton (?) ..but not sure. This seems to give quite good oversight and a clean separation of PL/BLL as the main form only access the BLL through one instance of a single class. But now I'm trying to figure out how to lay out the presentation layer. So with this I would like to understand a few points: Do you have all controls as members of the form class, or can you make sub classes where some controls only exist on lower levels? Like for example if you have a tab where all controls only interact with each other, and not the rest of the form, would it then be possible to make this a separate class that holds both controls and additional logic ? The first problem I get when trying this is with the events, as if I simply move an event handler method to another class than the form class, I get the message: Handles clause requires a WithEvents variable defined in the containing type or one of its base types.What does this mean? and is there an easy way around this? I would like to understand how a slightly more complex PL is designed, so I know what direction to move in for studying/developing this.

C# - Refactoring Tool That Works Across Solutions Files?
Feb 11, 2010All the refactoring tools for C# and VB.Net that I have seen only consider the source code in a single visual studio solution.For better or worse, our large (many related programs) system is spread over many solution files, however:All the code is below a single windows folder. Our nAnt based build system, builds all files in a windows folder to produce a single dll (bit more complex then this but not important for this question).Therefore ALL ".cs" and ".vb" files below the single root folder are part of the system.
So I am looking for refactoring and reverse engineering tools that take a single folder as input and act on all files below that folder.(The tools may need some help to decide what "public" and "internal" means, however most of the time "internal" means "in the same code tree" when a "code tree" is a folder that contains code and any child folders.)Now I am being greedy, I would like the tools to create a lot of all the refactorings that have been done and to be able to replay the refactorings. Then I could try out ideal and if they work, throw away my code, get the latest code, you do the refactorings and checkin the code before anyone else changes the files. (Likewise for when branches need merging)

Refactoring A Module Into A Class: Changing Shared Fields To Instance Fields
Nov 14, 2011I'm currently refactoring an old Visual Basic DLL (VB.Net), which stores all of its data in one module called Globaldefinitions as public fields. There are about 200 fields, referenced thousands of times all around the code:
Public Module Globaldefinitons
Public a As Short
...
Public zz10 As Double
[Code]...
I need to change the module into a class with non-shared fields. This means, each and every of these thousands of references needs to reference the instance of that class:
globalDefinitionsInstance.a = 5
How do I go about this efficiently?
Regular expressions operating on the source fall flat. Refactoring tools like Re-Sharper or CodeRush don't seem to offer this functionality. Visual Studio 2010 cannot do it automatically either.
Dont Get Any Data From Socket When Data Should Be There And No Exeptions Raised, Connection Is Open. Using DataAvailable To Wait For Data
Mar 24, 2011I have a problem reading data from an RFID-reader. I connect to the reader by tcp and wait for DataAvailable to be true, then reading the data until I got a end of data character. Then I just go back and waiting for a new DataAvailable. This is done in a own thread for the function.
There seems to be some kind of timeout, If I don't got any data in a couple of minutes, then it just sits there in the do/loop waiting for DataAvailable. I hold the card to the RFID reader, it beeps, but there is no data available. I don't get any exeptions, and the information says that the clientsocket is still connected. Are there anything more I can check?
If I put the card to the reader in a minute-interval it seems as this will never occur. So 2-3 minutes idle:ing seems to do this.
Here are my code to read data from the socket, I have taken away some irrelevant code:
Sub test(ByVal ip As String, ByVal port As Integer)
' this sub is meant to run forever

HSD 32 Bit Data Bus To Serial Converter Via A Microcontroller - Data Sniffer To Read The Data Bus (32Bit)
Sep 3, 2008Im working on a HSD 32 bit data bus to serial converter via a microcontroller. Now first I want to make a sort of data sniffer to read the data bus (32Bit) .All on the controller side is working and the stream of bytes are coming in via RS232 as 4 bytes in HEX like FD,A5,45,8B . I already converted the bytes in Dec and ASCII to determine what is passed true the bus and how fast and stuff.. Now that is all correct and working very well if the LSB (least significant bit) of the 32 data bus is Data line 0 and the MSB (most significant bit) is Data line 31 but if that is not the case I need to invert the 32Bits (like as I would invert the connector on the bus) . How do I best do this using the 4 bytes I send from the micro controller.
Example:
(MSB) 01001000 01100101 01101100 01110000 (LSB)
HEX= 48 65 6C 70
DEC= 72,101,108,112
ASCII= H E L P
I need to invert it with a button to:
(MSB) 00001110 00110110 10100110 00010010 (LSB)
HEX= 0E 36 A6 12
DEC= 14,54,166,18
ASCII= (SO) 6 : (DC2)
