Help with Snippet/paint. - Aero - 04-23-2011
I'm making a type of "Snippet" program that takes a screenshot of your, well screen obviously. Right now I have a capture, clear, and save button.
After the screenshot is captured I want to be able to Freehand draw on it but I can't seem to figure out how.
So far I have a small idea but I don't know what to do with it.
Underneath the public class-
Dim q As System.Drawing.Graphics
And in the picture box
Private Sub PictureBox1_MouseDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseDown
q.Draw....
But I don't know how to make it freehand on MouseDown.

What do you mean by "freehand", do you mean when the mouse it attempting to draw on the picture or when it has already drawn on the picture?

Just like in paint. Left click and draw. No straight lines or circles or squares.

Hmmm. Sounds like this could turn out pretty cool if you figure it out. Good luck.

This is not the best way to do it.. but for the sake of simplicity I think this will work for you. Adjust the code accordingly to fit your needs
Code:
Public Class Form1
Dim mDown As Boolean = False
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown
mDown = True
End Sub
Private Sub PictureBox1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseUp
mDown = False
End Sub
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
If mDown Then
Me.Text = "down"
Else
Me.Text = "up"
End If
End Sub
