I am making a lunar lander game that randomizes the terrain for each new game, so each game is different. For my game, I am creating a graphics object that draws a closed curve for the terrain of the game. I am trying to then detect if a picture object collides with the graphics object.[code]...

View 1 RepliesI am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
I'm building a maze application in visual basic. The game relies on two variables, X and Y which are integers. There's a timer which basically invalidates the whole form for a redraw. Now my question is, that there are various squares and rectangles dotted around the form. How would I create a handler, or something as such to detect if the square that the form draws is touching these objects?[code]...
View 1 RepliesIs there a way to detect if a object is over an other, and then do an action?Eg:There's a label and a picturebox.When I change the label's location it goes on top of the picturebox.Is there a way I can detect it, so that once it's on top of the picturebox I show a messagebox or so?

I want to be able to do collision detection with graphics and a picturebox. I have a character that is moving on the screen and I have drawn both the background and the character using graphics. I have put a picturebox in place of the block that is suppose to be like a square which the character has to jump over. How would I do this?
View 6 RepliesWhen I do my form_paint event, I have quite a lot to redraw, so I'm breaking into into severals subs to make it easier to read. I'm passing the 'e' variable into my subs as shown below, is this correct?
Private Sub frmMain_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
DrawMap(e)
End Sub
Private Sub DrawMap(ByVal e As System.Windows.Forms.PaintEventArgs)
End Sub
Am I right in copying that whole 'e as system.windows....' etc line from the form_paint details into my subs details?Just to clarify, the sub will draw directly onto the form.
Is there a way to create an image from a graphics object?
View 3 RepliesWe would like to know whether there is any way to interrogate a Graphics object and determine whether it is to be used to print or to render to some other canvas. We're aware of an API call that can be used but would prefer to avoid that route if possible. There's also the possibility of simply passing a flag in with the Graphics object that is True from a PrintPage event handler and False from elsewhere, but that's not ideal either. We're looking for a managed property or method accessible via the Graphics class itself, but nothing's jumping out.
View 20 RepliesI have been trying to draw spirals in vb.net. Here's a link to the formula [URL]. here's what I was trying to do. The code below is just drawing points which I was later going to edit to connect from point to point as soon as i got the spiral function working.
Function Draw()
Dim iImageCenterPointH As Integer = pbOut.Height / 2
Dim iImageCenterPointW As Integer = pbOut.Width / 2
Dim iCircleSpace As Integer = 10

I need serious advice here please. I use Visual Basic Graphics Programming by Rod Stephens as a reference, and I have visited his site vb-helper.com to try some of his tutorials. I tried the scribble application and it's working out fine (you can download the snippet from his site).
What I have trouble with is zooming in. I am not sure where to start. I would like to zoom in to x2, x3 and etc. of the bitmap I am working on and I would like to be able to continue to edit the bitmap. This would mean that I have a larger pixel brush under the mouse cursor, to lay down pixels. So a x2 zoom would mean a 2 x 2 pixel.
Has someone done this. Do you have a reference I can use for this. This kind of editing is standard in almost every paint package. Even Microsoft Paint, but there is not too much basic information on how it fits together in code for vb .net. So I am looking for someone to point me in the right direction. As I said, I am using the scribble application as a base, so here is the link. [URL]..

View 1 RepliesI have managed to build the basic Picture Viewer Program. Now Remember the program I am working on is for a Digital Picture Frame there is NO wirless network adapter on the old pc and there is no keyboard going to be attached to the laptop so the program must launch its self (ill put a short Cut in the windows startup folder). I got a picture box that excepts the picture file it covers the whole form! (when there is a picture in the picturebox1 it fits the screen) My form one covers the entire screen (I set the windows border from scalable to none). I need to make my program scan for picture files on different drives and then every 30 seconds or so choose a random picture from the usb drive and display it Posted below is my code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
PictureBox1.ImageLocation = OpenFileDialog1.FileName ' want to remove this feature so the user cant see this

I'm using DirectDraw to create a (very) simple little movement game... (so far not really a game, but hey, gotta start somewhere) And I'm having a little trouble with my collision detection... ok, it's probably not conventional collision detection, but I'm just learning so far...I have a few surfaces set up etcetc, and have animated a sprite on a tile based background... but the problem is whenever I collide with a certain tile (which I've set as unpassable) from the top or the left, it screws the position of my player immensely... this is quite a headache as I can't seem to see a problem...
ps. Another thing, I can't seem to be able to open my pictures without using the entire directory.
I have a scanned document in my system. It's a tiff file. You will see below the code i have written. The problem is that i get an error message. The message is like this "A Graphics object cannot be created from an image that has an indexed pixel format." [Code]
View 3 RepliesI need to make a basic drawing program in VB that can do three things:
"Draw" with a brush of some sort
Clear the screen
Perform a flood-fill (paintbucket action)
I decided to do the first two tasks first, and got them to work, but the third task completely eludes me. Every way I try seems to pile on exceptions, and every flood-fill algorithm I find seems to require a bitmap, rather than a Graphics() object. Is there any way to accomplish a flood-fill using a Graphics object, or must I restart the project using a bitmap?

View 6 RepliesI currently have a graphics object g where I am drawing lines and ellipses on with the command
g.DrawEllipse(definedPen, Fc, Fr, Tc, Tr)

This works fine. However what I can�t find out how to do is place text onto the graphics object at a specified row & column.
Pretty self-explanatory question. I'm trying to see if I can do sprite animation in Visual Basic and, while I can use a Graphics object to translate a bitmap down a few pixels, I have absolutely no idea how to erase the bitmap drawn in its former position. Is there any way to erase the old image before the new image is drawn onto the form?

View 5 RepliesIt might not be the best and i'm currently finishing on adding certain features, commenting it fully and possibly tutorializing it, but if ur needing an object to detect drive connections and disconnections and a lil more, here ya go. This dll is "Events 'R' Us" It also contains some simple public functions - findDrives(driveType) will find on command all of a specific drive type and return a dictionary of values - byteConverter and getMB, getGB, etc..
will convert bytes to larger metric values - getPercentage will simply get percentage of 2 figures and return as decimaland i'll give away more soon, just wanna get this out now, see if anyone has any use for it, almost every thing that can error has an error event and thus far i can only get one to fire (if usb is pushed in and pulled out really fast over and over again, i know where it fires, it's no biggie at moment)
