Make A MVC 2 Json Serializable Structure With Apropriate PK Array Keys?
Jan 1, 2010I have a table with a Int PK column and a name. I want to load them into an object of some sort and return them using Json() ActionResult in MVC 2. I am having a hard time finding a built-in structure that is supported for serialization that keeps a simple key/value structure in tact.
Ultimately I would like to do something like:
Function JsonList() As ActionResult
Dim Things = New Dictionary(Of Integer, String)

Get MD5 Of Serializable Class
Feb 27, 2011I have a class that is serializable. I would like to compute the MD5 of it. I already had a function in the project to get a MD5 from a Stream, so I reused it, and created a function to convert an object to a memorystream. The code is as follows. Does anyone see any problems, but more to the point, is there an easier way to do this that I'm simply missing?

C# - Serializable Partial Classes?
May 29, 2009I have the follow VB.NET class definition:<Serializable()> Partial Public Class Customers End Class
Inside another file I have the same thing (with different methods and variables of course). When I compile, I get the following error:Attribute 'SerializableAttribute' cannot be applied multiple times.The error is pretty self explanatory. My question is though, if I just mark the one class as Serializable(), can I assume the entire class with be marked as serializable()? In other words, Do I only need the serializable() tag in 1 spot in the class?

What Class For Serializable Multidimensional Arrays
Feb 19, 2009EDIT: SI have a web service which uses a class of functions in order to return data used in various business processes (via InfoPath). One of the functions takes a given SQLCommand object and executes it into a SQLDataReader. Now depending on the SQL command text used this may return one or many rows of one or many columns. So what is the best class for this function to return bearing in mind it needs to be serialized by the web service.

View 4 RepliesUser Interface Not Reflecting Changes Make?
Mar 23, 2012Basically the question is, Why are NONE of the changes I've been making in the designer reflecting on the program when it runs ?'none' is in bold because I've tried moving everything around and nothing seems to be affecting it, it's like it's reading from a different design file, I tried reloading the project and that did nothing, and none of my code affects position of any items on the form (way too much to post it all)
View 1 RepliesConcurrency Control With Serializable Isolation Level?
Jun 28, 2011I have to handle concurrency control and I used SqlClient.SqlTransaction with IsolationLevel.Serializable level. In that transaction, I do 3 works:
1. Select the latest updated time from a record of a table
2. Compare the latest updated time with a stored time paramater
3. If the result form comparision is "same" I will update that record
But my problem is, when 2 transactions is run at almost the same time.

Serialize An Object, Exception Because Form Is Not Serializable
Jul 28, 2010I have a class called Truck and a form called frmTruck I have some code like this in a method. It recieves obj as Truck
Dim ms As New MemoryStream(1000)
Dim bf As New BinaryFormatter(Nothing, New StreamingContext(StreamingContextStates.Clone))
bf.Serialize(ms, obj)
To simplify my code, I have basically something like this for frmTruck:
public class frmTruck
private truckValue as Truck
public sub DoSomething()

During the LoadTruckFromDatabase function I call the SerializeTruck method, here everything goes fine. But when I call the SerializeTruck just before End sub of DoSomething, it goes wrong I get an exception saying that frmTruck is not serializable My truckinstance doesn't have any references to frmTruck...

Interface And Graphics :: Best Way To Make A 'tile Selector' Box?
Jan 16, 2011So now I will try to make something more complex, still playing around with this graphics thing.I want a picturebox to display a tileset (a bunch of 32x32 tiles normally used for creating game levels etc), the picturebox is inside a container (which has autoscroll ON). The picturebox is larger than the container, so the container will make scrollbars automatically.Now, I need to be able to choose a tile or multiple tiles (if I click & drag the mouse)Basically I want to draw a 32x32 "red" box over each selected tile (so the user knows what tiles are selected).So first of all, I need to know when the mouse clicks the picture. Good. It works.Now, I need to know which 32x32 tile was clicked. Well, I think I can calculate that just fine.BUT, what if the user drags the mouse while clicking on a tile? I want to support multiple tiles selected, but I am clueless about tracking what tiles were chosen.If we solve that problem, I would have another curiosity: You know the "red boxes" that tell you which tiles are selected? What would happen if I dragged the scroll bar? I need the redboxes to move along with the picture, and hide if they go to an invisible area.

View 4 RepliesInterface And Graphics :: Make A Thumbnail From An Image?
Jul 11, 2004I am trying to incorporate in my vbdotnet application a form in which I would like to make a thumbnail from an image. So what I have is two picture boxes, one with the source image and the other with the destination image, I would like to crop the image from picture box 1 and display it on picture box 2, but the way I wan to crop it is not giving the coordinates of the selected area box but to simulate a selection area box in which the mouse can move the box and select the area of the picture to be cropped. This selection area box would give me the coordinates i need in order to proceed the cropping. The problem is I don't know how to create this selection area box. It is like doing the cropping on a graphic design software like Macromedia Fireworks, Adobe photoshop, even paint.
View 5 RepliesMake A Page Based Interface Such As An Installer?
Jun 22, 2009What would be the most clean & efficient method to make a page based interface, such as an installer?
I've had a few ideas, I could make a class for each control i'm going to use that has a Page ID number, and compare that against a global current page number, except I want it to be reusable, so that would mean i'd have to make a class for every control.

View 2 RepliesMake Base Interface For Generic Classes?
May 25, 2010I'm trying to create a base interface for a class of mine that uses generics. However, I cannot figure out how to declare a property of the interface when its type won't be defined until the class is initialized.
To clarify, consider List(of T), which according to msdn, implements IList (among other things). Note that IList is not the same as its generic counterpart IList(Of T). So that mean any List(of T) can be converted to IList, which simply returns an object for its items. That's what I want to do with MyClass(of T), be able to cast it as IMyClass regardless of what T is.
But when I try such as:
Interface IMyClass
Prop A as Object
Class MyClass(of T) Implements IMyClass
Prop A as T Implements IMyClass.A
I get a signature error for the last line, even though object is broader than T. What am I doing wrong, or how exactly did Microsoft manage to make List(of T) implement IList?

VS 2008 - Custom Control 'Serializable' - Contains A List(Of Panel)
Nov 29, 2010I'm trying to create a custom control that contains a List(Of Panel). I quickly ran into an error about the base class Panel being nonserializable. So I created my own class that inherits from Panel and implemented the ISerializable interface. At the surface, everything appears to work, at least everything at design time. I don't know what would happen if I tried to run the application. Anyway, the errors occur when I try to open a file that contains my custom control. For example, I create a new Windows Form and add my custom control to it. I save the Form and close it.
Then I try to open the form and get the following error: Object of type 'MyTestApplication.SerializablePanel[]' cannot be converted to type 'MyTestApplication.SerializablePanel[]'.
I don't know what I'm doing wrong? I've opened the XML file to see what it's actually writing, and read the header notes about using binary base64 serialization. I think that's what I'm using, but I'm not sure.
Below is the code for the class SerializablePanel:
Imports System.Runtime.Serialization

C# - Arrays - Use The IEnumerable<T> Interface And Make It Type Specific
Mar 1, 2011In many projects I work on, whenever I have to return a read only collection, I use the IEnumerable<T> interface and make it type specific like so:
CODE:
Most of the time, I return a List but in some functions and read only properties I return an array which also serves the purpose alright by kind courtesy of Extension Methods.
My question is am I violating any design principles by returning IEnumerable<T>s instead of specific types (e.g.: List<T>, HashSet<T>, Stack<T> or Arrays)?
