In this Visual Basic .NET tutorial I’ll teach to how to create a simple drawing application and save your picture to an image file.
We’ll be using a PictureBox control as our drawing surface, and we’ll use a ColorDialog to change our paintbrush color, as well as a ComboBox to select our brush size.
TUTORIAL FEATURES:
Mouse Events – Capturing Mouse Coordinates, Clicks, and Drawing
Subs – Creating a paint brush
Form Controls – PictureBox, ComboBox, ColorDialog, Button
Bitmap – Create and Copy Images, Saving to file

What about if I have a list view displaying images and i want to save them in a created directory, how can I do so?
I suggest for you 😉
What about if you create tut about how to open from openfiledialog picture draw to picture and save it on desktop example ?
It just draws a bunch of dots if the mouse moves too fast. Please help.
plz help picturebox saves in white image whitout the drawing
hello
thank you for this video
I’m asking if you can upload the source code plz
There are no mistakes, just happy little accidents….
Also, i want to draw to an image, and it wont let me, a custom image i can select with a opendialog and it wont draw to it, could you help me?
what if i want to save it as gif? i tried and it made the image all weird looking and bad quality but it was a gif from the start and looked better. how do i get full quality rendering on gifs?
wow cool!!!
For your second idea on the thing without rectangles, my program crashes when trying to use this
dim thickness as integer = “1”
dim thickness1 as string = thickness.ToString + “.0F”
or this dim thickness1 as string = thickness + “.0F”
mousemove:
qMouse.Enqueue(e.Location)
PaintBrush(thickness)
Very impressive…
WHAT IF… we could build our own Photo viewer, using that method (having a Table to store the paths from photos and retrieve the paths for the Form) ?
That would be… really FUN !
Thank you for your shared amazing abilities.
A little bit of editing of the code I created a proper save dialog…
