Drawing Graphics - How To Clear Image In PictureBox

picImage.Image = PictureBox1.Image

The cycles for is for show the rectangules and works fine. but

The image is clear but the rectangles are showed and then unshowed.
Graphics - How To Clear Form Background
Feb 23, 2012I am trying to create a simply bouncy ball application in VB net; I am using a timer and the FillEllipse() method to try ad create a new circle at every tick of the timer.
Code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim Gr As Graphics = Me.CreateGraphics
Gr.FillEllipse(Brushes.Teal, X, Y, W, H)
CollisionDetect()
X = X + X_Dir
Y = Y + Y_Dir
Gr.Dispose()
End Sub
The result? The form continously draws onto itself, without clearing the last circle. This means that you end up with a 'line' of spheres together.
To clarify:
X is well, the X-Coords
Y is Y- Y-Coords
X_Dir is an integer, it is added to every iteration of the loop so the next time the loop iterates, it'll be at a different location;
Y_Dir is the same but for the Y Coords;
CollisionDetect() Is empty. It is yet to be filled, it will handle the collision with the sides of the forms. W, H are width and height, respectively.

View 3 RepliesClear A Picturebox So The Picture In It Doesn't Show Up?
Dec 11, 2011How do you make the image in a picturebox vanish when you change an option? I have tried a few different ways that i have seen but none have worked. I have it set so when i change an option in a listbox it will change the picture and data in other controls, however one option in the listbox has no data to fill in those controls and so gets left blank. However when i click on that option right now the images that were in the picturebox before get left behind until i click on another option that has a picture. So how do i remove the picture from the box?
View 4 RepliesPicturebox - Clear The Background Double Buffer Before The Flicker
Jun 10, 2011I have a htpc project that I am working on. The main program loads dlls which are basically other win forms. On each of these forms, including the main program, I use a picturebox (double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I go from the main program to the dll, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker?

.net - Graphics.Drawstring Looks Nice In PictureBox But Horrible In A Bitmap?
Aug 5, 2010I am trying to use DrawString to write text as an image and then rotate it 90 degrees. It works fine with both a bitmap or directly on a PictureBox, but the big difference is in the quality. The PictureBox text drawn has great quality and looks nice. When I draw it on an image it looks horrible and blocky. I've made a few changes to try and get it to look nicer, but it doesn't look nearly as nice as it should.
Sample code:Use a Windows Forms project and place 2 picture boxes on it and a button and run it with the following code to see what I mean:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Interface And Graphics :: Animated Gif In Picturebox, Slow & Choppy?
Apr 3, 2009I've been searching for days. I can't find anything that I think is going to work. I've probably read the answer and skipped it because I don't get it. I'm new. I've researched multithreading, sub routines and webbrowser. The webbrowser thing doesn't seem professional to me.
All I want is the animation to be smooth when it's displayed and to have it integrated into the app so it's not called from the local drive.The animated gif is in PictureBox3. Please point me in the right direction. I really don't want to use a static image.

Interface And Graphics :: Printing ALL Content In Large PictureBox Which Has Scrollbars?
Feb 5, 2009My project needs to print a large PictureBox which during runtime only part of it is shown (as it's too large, width=4000 pixels and height= 2000 pixels) and to see the rest of the picturebox, user needs to scroll through the vertical and horizontal bars. On top of the picturebox, there are many controls which are loaded and positioned by user on run-time. Those include lines, labels, another picturebox
with image and user-defined controls. Now, i need to write a print function which will print that picturebox to not too many pages in A4 size or A3 size. Not too many means less than 5 for both paper size.
1) How can i print the whole picturebox with all its contents and go to next printing page until the whole PictureBox is printed? I tried using the following code but
(i)The image of picturebox inside that picture box and user-defined control are not printed whereas others are printed. Why is that so? How can i print the picturebox including both the "un-printed"?
(ii) Even i can print out the picturebox, only the part where the picturebox is shown is printed. How can i print the whole picturebox including those parts which needs scrolling to reach?
Private Sub CmdPrint_Click()
Dim rv As Long
'Picture1 is the picturebox to be printed.
