I have a program where I use a picture box (pAudiogram) to display a template. Then I use Graphics (myLine) to plot things on this picture box. Some example code is below:
Dim myBluePen As New Pen(Color.Blue) : myBluePen.Width = 2
Dim myRedPen As New Pen(Color.Red) : myRedPen.Width = 2
Dim myLine As Graphics = pAudiogram.CreateGraphics

I have an application that has a list of point and I can choose a tool and draw one image to different locations then remove them if I wish, and when I finish editing those images, I can then pick another tool . The images are supposed to go away that were drawn by e.graphics but they only do when I click in the picturebox. How can I hide the images or delete them from graphics when I choose another imageHere's the paint event alone

View 1 RepliesI draw some graphics on a picture box. However, I want to change the width and height of the picture box so that the drawn graphics fit exactly in the picture box (during run time, where graphics may change). How can I do this, or how can I get the region of the drawn graphics so that I can change the width and the height of the picture box manually.
View 8 RepliesI'm creating a custom form that is composed of a inner stroke, outer stroke, and rounded rectangular background. When the form is initially drawn its drawn fine without errors but once i re size it, the old form is still drawn and the new form is drawn below it but once i minimize the form and restore it, it goes back to normal (only the new form is being drawn).

I'm making a plotting program. The panel (vs picturebox) is necessary because the data doesn't all fit into one screen so scrollbars are needed. I'm using graphics to draw the background layer and buttons for the data points.
When I scroll, the background is redrawn incorrectly since the top left corner of the panel is no longer the top left data point. Ideally, I'd like to prevent the background layer from redrawing entirely (after the initial draw). Alternatively, how do I take in consideration the new position of the scrolled panel in drawing the shapes & lines in the background layer?
Currently I'm working on a retro-pong game using graphics. The problem is, my code keeps drawing new ellipses every time, and doesn't discard the old ones.

I 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.

I'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.
