I've created a polygon shape and filled which fills blue on startup.Upon toggling a check box it should be filled yellow.It doesn't go yellow (unless i step through in debugging).

I have a RadioButtonList control which triggers a Sub LegalGaps on SelectedItemChanged event. This Sub creates and fills in an array the size of which depends on the User's choice of radiobutton options. The second Sub AvailableDays shall be able to read that array and highlight the days in the Calendar control accordingly on DayRender event. May I somehow declare an internally created variable a public one?

i'm making an twitter app. but i'm having a problem..In my listbox there is a list of username's i have to sent a tweet.this is the code i'm using:
For i As Integer = 0 To ListBox1.Items.Count - 1
ListBox1.SelectedIndex = i
Dim value1 As String = ListBox1.SelectedItem.ToString
Dim value2 As String = value1.Replace("http://twitter.com/", "")
[code]....
but it doesn't work..it goes super fast and only fills in the last listboxitem.i want now that every 10 secs a new listbox item is filled in in the status box on twitter and posts the tweet.
I can hide my startup form (or make it appear hidden) on startup. I can start my app on windows startup--through registry values--if the user checks a checkbox.
But if the app starts up on windows startup, I want the form to be hidden, so the program can just keep working without bothering anyone. If it starts up because the user started it, I want the form to be showing, because the user probably wants to change some settings or something.
I'm working with referenced VB6 DLL's. The problem is that the results of a method/function call are not the same. Below the code examples:
First VB.Net Dim Validations() As String myErr = myEntry.ValidateLine(Validations)
When validation fails, the string array Validations is filled with the error description string. I've tried to accomplish the same in C#:
private string[] valArray = null;
sdkError = sdkEntry.ValidateLine(valArray);
Does anyone have an idea why I can't get C# to fill the string array? Additionally, the function in VB is called with ref to a System.Array ValidateLine(ref System.Array ValErrors), perhaps it has something to do with this?
I'm having an issue when passing an object of type Dictionary(Of Int16, Polygon) as an argument to a backgroundworker so the background worker is able to access the Polygons in the Dictionary.

View 2 RepliesI'm making a program where the user fills out info, then they click one button and the program takes a screenshot of the form, then they click another button and the screenshot gets saved. I'm having a couple problems with my code though. For one, I'm trying to make the screenshot go to an invisible picturebox to make saving easier, but I cant figure out how to make the image go to the picturebox. The other problem is that I want it to automatically save without showing the dialog, but so far, it won't save.

I have a collection of latitudes and longitudes and I'll be grabbing sets of these and want to draw a polygon based on them.The datasets won't be the outline so will need an algorithm to establish which ones make up the outline of a polygon containing all the latitudes and longitudes supplied. This polygon needs to be flexible so the polygon can be concave if the points dictate that.
My code below produces a horrible looking polygon. As explain in my first post I want to create a nice concave or convex polygon based on the latlng's provided.Just need a way of plotting the outer latlngs.
function initialize() {
var myLatLng = new google.maps.LatLng(51.407431, -0.727142);

I'm making a game for a school project We've created a character that moves around the screen and creates blocks behind him as he moves around.We want to make it so that when the character moves from one edge of the screen to another, it fills the screen. So in order to do this we have a Points array that stores every point the character touches on his way to a wall.We then fill the Points array with "formsurface.fillPolygon(Points)"Now I'm wondering is there anyway we can retrieve all the points that are WITHIN or INSIDE the Points array we made? ( remember the points array simply contains the outline or the path the character created, we're filling inside that outline)

I'm working on a small freeware application in Visual Studio 2008 Standard that will match geographic data to a geographic position. For this I need some mathemathical functions and one of them is how to detect if a point is inside a polygon. There's a great solution for this from the Microsoft team at: [URL]
but it is in a different programming language that I do not know anything about. How can I use these functions in my program? I'm afraid that if I try to rewrite them in Visual Basic I'll make mistakes that I can't detect. To be complete, I'm not using screen graphics so I really need a mathemathical solution.
I am developing an application, for a university project, which is using GDI to draw a flag, my application is also equiped with an undo stack, which is, essensially, where the problem is, so what happens is: I push the draw button to draw a box, when I do that, the solution normally creates the box and stores the object to the undo stack; however, when I ask it to undo the box, and refresh the panel, it randomly adds, endless threads to the undo stack, additionally, everytime that I set the panel to refresh in the undo procedure, it affects the draw procedure; therefore, when I tell it to draw a box, it fills the undo stach with five threads at a time, sometimes, it fills it with much more than five, and sometimes it keeps filling up the undo stack, untill I stop the debugging proccess. This is my code:

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)
