VS 2008 : Drawing With Multiple Colors In A PictureBox?
Apr 13, 2011I'm basically trying to make a simple, easy-to-use, paint program. I seem to be having problems with using multiple colors in the PictureBox1_Paint option. It draws the graphics but when you change the brush color and click in the picturebox it changes the colors of the previous graphics to the color you are currently trying to use. I need it to allow multiple colors.
Here's the code that I'm currently using..

Drawing 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

Picturebox Transparency - App Has Scrolling Images In The Background And A Picturebox On Top
Feb 28, 2009My app has scrolling images in the background and a picturebox on top. The image in the picturebox has transparent parts. How can It so that the transparent parts show whatever is belo the picture box, not the form background? I have tried taking screenshots and positioning them as background but this just freezes the app.
Dim ScreenSize As Size = New Size(154, 83)
Dim screenGrab As New Bitmap(154, 83)

Make Several PictureBox Images Randomly Visible = False And Then Back To Visible = True Giving The Appearance Of Flashing Or Blinking Images?
Jun 28, 2010I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

Graphics Drawing Images Events
Aug 3, 2010I have been researching for a while, and now am converting my project from using forms to do transparencies to just drawing the images.

Here is what I am using: [Code] Now, I know these are not controls, but is there any possible way to make these drawn images have a click-able event fire?
View 4 RepliesMulti-Threaded Drawing Images In A Row
Apr 5, 2011I am drawing five images in a row. The five are the same thing at five different zoom levels. Therefore, only one of the five will be displayed at any one time, but the others have to be there because there can be over 100 images being displayed on the screen at any one time, and each drawing is quite complicated. If I were to draw them all on the fly, then zooming would require that all 115 images be recreated and redrawn with each zoom. That's painful. To avoid that, I draw all five zoom levels of each image. When the user iteracts with the form, they will be interacting with, at most, two of the images, so when they interact with the form, only two of the 115 have to be redrawn, though those two have to have all five zoom levels drawn, for a total of 10 images.

Basics: Drawing Graph With Picturebox - Image
Jan 9, 2011I am new to vb.net, from VB6. Trying to understand drawing a simple line graph into a picturebox, which was so simple in VB6 ! From code snippets, I can see the basic idea using an bitimage to draw the lines and then showing it in a picturebox. I don't understand how to (simulate) scaling of the bitmap's x/y scales like you could do with VB6's .Scale.

Embed A Panel Or Picturebox Containing Controls Or Images Within An Outer Panel Or Picturebox?
Mar 1, 2012In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?
View 4 RepliesDrawing A String On A Picturebox In The Form Load Event?
Jun 13, 2010I have a question about drawing a string on a picturebox in the form load event. So I have a picturebox on a form and in the form load event of this form I have this code:
Dim gx As Graphics = PictureX.CreateGraphics
Dim f As Font = New Font("Arial", 8)
Dim brr As Brush = New SolidBrush(Color.Black)
' Add the copyright text
gx.DrawString("1", f, brr, 2, 5)
But when I load the program nothing is drawn in the picturebox. Is there something wrong with the code or should I use the paint event of the picturebox?
By the way I also used this code in another program and there it works flawlessly, everything is drawn in the right place there when i load the program.
