Dec 25, 2009I used a picturebox to allow user draw lines by mouse. I used this code in mouse down:
Dim D As New System.Drawing.Pen(DrawingColor, 2)
Dim g As Graphics = PB.CreateGraphics()
g.DrawLine(D, X1, Y1, X2, Y2)
but when a window appear on front of picturebox... its seams that picturebox redraw itself, so drawn lines erased.

View 2 RepliesDrawing On Picturebox Vs Drawing On Form?
Feb 18, 2012I need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

C# - Multithreaded Drawing In .NET?
Jul 24, 2010(Edit: to clarify, my main goal is concurrency, but not necessarily for multi-core machines)
I'm fairly new to all concepts on concurrency, but I figured out I needed to have parallel drawing routines, for a number of reasons:
I wanted to draw different portions of a graphic separatedly (background refreshed less often than foreground, kept on a buffer). I wanted control about priority (More priority to UI responsiveness than drawing a complex graph). I wanted to have per-frame drawing calculations multithreaded. I wanted to offer cancelling for complex on-buffer drawing routines.
However, being such a beginner, my code soon looked like a mess and refactoring or bug-fixing became so awkward that I decided I need to play more with it before doing anything serious.
So, I'd like to know how to make clean, easy to mantain .NET multithreaded code that makes sense when I look at it after waking up the next day. The bigest issue I had was structuring the application so all parts talk to each other in a smart (as opposed to awkward and hacky) way.
I have a preference for sources that I can digest in my free time (e.g., not a 500+ pages treatise on concurrency) and for C#/VB.NET, up to the latest version (since I see there have been advances). Basically I want something straight to the point so I can get started by playing with the concepts on my toy projects.

Drawing The New Pictureboxes?
Jun 16, 2009what i'm trying to do is make sort of a picturebox game. I have a picturebox name p1 that i got to move with the arrow keys on the keyboard. What I was tryna do next was to have it so that whenever I pressed the spacebar on that a new picturebox would be created, originate from p1's location and then go up 5 pixels at a time. so here's my code that i tried;
Dim Loc As Point
Dim shot2 As New PictureBox
If e.KeyCode = Windows.Forms.Keys.Space Then
shot2.Visible = True
[code].....
I have that under the keydown event by the way. So even thou vb didnt have conflicts with my code. But when I press the spacebar nothing happens.

Drawing Without Redrawing?
Apr 19, 2011In a simple hang man game I am I have a a method called wrong(). In this method I increase an integer variable (wrongGuesses) by one and Panel1 is refreshed. Panel1 is the control that I am drawing the actual hangman on and in its paint event I'm using a Select Case structure to draw each part. Here is my code for the wrong() method and the Panel1 paint event.
The problem I'm having is that every time Panel1 is refreshed everything is erased and and the paint event only draws a single part (head, body, left arm, etc). I realize I could redraw the entire stick man every time, but that seems inefficient. Also, I realize that I could Invalidate() each part of the stick man and then Update(), but that I was hoping for a simpler method.
