Wpf - Create 'object' Containing A Polygon And Variables And Other Data Elements
Apr 6, 2012
I'm trying to write a simple game ui, it is grid/tile based, and i have the grid built using grid column and row definitions and I'm successfully placing objects in various grid locations. I am currently stuck as trying to build the player object. I want a single object reference to represent the various components of the players piece.
Currently I am using a polygon to represent the piece on the grid. Eventually I want to replace this with images or something. I want to add in properties for what weapon and armor it has equipped I want properties for health
Essentially in code i want something like this
dim player1 as new playerobject
player1.polygon.points = 0,0 60,30 0,60
player1.health = 100
[Code]....
I can instantiate all this as separate variables etc, but I'd like to have a singular reference that contains all the variables, properties, objects, controls etc.
I'm using vb .net in vs 2010 (and no, I'm not looking to write in something else)

I have a situation where I have an xml document that has a bunch of elements that I basically use as data variables. I populate the variables from various sources and then transform the xml file to an html file for user viewing.having to remember the names of all the data elements in the file is somewhat tedious. Is there a way to generate a strongly typed xml document object so that one can simply dot into the various data elements?

I am developing the map tool application in vb.net where user can create maps. I gave the check boxes for show/hide the layers of map like village boundary(polygon), plot boundary(Polygon), roads(Lines), bore wells(points), dug wells(points), schools(points).
I am using the function RedrawMap for displaying various layers of maps as user checked the check boxes. If user click village boundary map shows the village boundary etc on panel control named "picMap".
The problem i am facing is when user check the village boundary layer map shows the boundary but when user check the next polygon layer i.e. plot boundary layer it gives the error message "5:Object is currently in use elsewhere.".
My code is as follows:
Public Sub RedrawMap(ByVal index As Integer)
Dim f As Font
'Object Style
Dim Size1 As Short
[code]....

I've got 3 forms that have exactly the same functions, so I decided to create an interface.
public Interface IExample
public sub Add()
Public sub Edit()
[code]....
At this point, objfrmExample is now instantiated, even though I've not done a "objfrmExpample = new [what-goes-here?] " and I'm curious as to why.I could possibly guess that because you cannot instantiate an interface variable, then vb.net automatically creates an instance. But thats just a guess. The question is , what is meant by declaring a variable of type Interface, and how does it work?

I'm working in VS2010 on a visual basic application. It takes in serial port data, writes it to an access database, and then graphs the data.The data only comes in once every minute, so it's not like I'm building an oscilloscope. Right now, the chart is reading from the database using a table adapter and graphing just fine, so long as I keep the number of records in the database low.If I add too many records to the database, the chart shows a red "X" through it. I've played with changing the axes, but it is still a problem.I don't really need to graph the whole database.The twenty most recent records would suffice.How can I make a chart series with only a small subset of the database in it.Perhaps it cold be populated with a query?

Here's my json:
{"d":{"key1":"value1",
"key2":"value2"}}
Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?
The reason my json is structured like this is that the webmethod that I'm calling via jquery is returning a dictionary. If it's impossible to work with the above, what do I need to change about the way I'm returning the data?
Here's an outline of my webmethod:
<WebMethod()> _
Public Function Foo(ByVal Input As String) As Dictionary(Of String, String)
Dim Results As New Dictionary(Of String, String)

I have a function that will be passed an object that contains MANY variables. These variables all get stored in a database. Later a new object will be passed to my function and most of the time it will be identical. But sometimes one or two variables will be different and I'll have to take various actions based on those changes. Other than looping through every variable and comparing it to every stored version of that variable, how might I do this? Can I some how generate a hash value for an entire object? Since the object will be the same most if the times it is passed to me this would be a quick way to determine that nothing has changed.

I want to make my own xml-serializer class because I need other formatting than the System.Xml.Serialization.XmlSerializer does. My idea is to treat properties of primitive type (such as Integer, Double, String) as XmlAttributes.To properly implement a usable Xml-Serialization I need to know which variables point to the same object (the binary serialization behaves this way). Because one object should be serialized only once in order that the connections don't get lost.On the side of XmlSerialisation I have the idea to insert a path to the class as a special XmlAttribute.

How would I create a list of elements in VB.NET, save it to a .dat file, and make Ruby re-create such list (as an array) with such elements (they will be strings, booleans and integers)?

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

I'm building a litle console app that involves a control hierarchy -- there are screens, and inside of screens you can compose controls together.
You can add controls to a screen by declaring member variables (which all inherit from AresControl). The control constructor takes a simple coordinate pair. It looks like this:
Public Class IntroScreen : Inherits AresScreen
'Controls
Private LabelSelect As New LabelControl(72, 0)
[Code]....
This would result in cleaner, convention-based code. But try as I might, I can't get it to work - I can walk the member variables of a type, but I need to walk the member variables of a live object.

I am writting a VB .net (3.5) applivcation which references a COM object. I can call methods on the COM object fine provided that they don't require any variables to be passed. I have been told that you can only pass a maximum of one varaible to a COM object, I really don't believe that it true
for example
objsession.connect()
works fine

I am trying to figure out how to use variables to define which object to update. I could of course use a case statement to pick the object based on a variable, but it seems to me like there should be a more direct way. Here is a smaller example of what I would like to do.In my form I have 4 picture boxes (pbox1, pbox2, pbox3, and pbox4). I then want to change the image in one of the boxes, but the box I want to change will be determined by a variable (say maybe a randomly generated number). Is there some way to dynamically concatenate the "pbox" with the number that VB would understand it and use it as an object?In this example I could easily build a case statement to handle the selection, but in my real program there will be many more than 4 options.

I wish to read a web page that had various frames and div elements.To start with I would like to create a routine that justs lists all of those elements values and then display each element name and its value so I know what I have and how to reference it later on.I have been using the WebBrowser control and have managed to do a few basic things so far like go to a website and auto login.

In VB.Net is there any difference between the following three ways of initializing object variables
Method 1
Dim commandObject As SqlCommand
commandObject = New SqlCommand("MadeUpCommand")
Method 2
Dim commandObject As SqlCommand = New SqlCommand("MadeUpCommand")
Method 3
Dim commandObject As New SqlCommand("MadeUpCommand")
Is one more efficient than the others, or are they effectively all the same?

I have an object that is defined as a global variable based on custom class. Within that class I have an event that gets fired a certain intervals. These events are fired on the same thread as where the object is declared. How do I create a global object, but have the events within that object fire on a separate thread?
