moving form by holding mouse on picture

I want to be able to hold the left button on the mouse down while over a picture and then move the mouse and have the form follow the mouse

i tried using PictureBox1_MouseDown and watching for when the mouse was moving, but i couldnt get it :S

Are you using .Net?

use "sendmessage" in API

Why? Try:


Private m_x As Integer
Private m_y As Integer

Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown

If e.Button = MouseButtons.Left Then
m_x = e.X
m_y = e.Y
End If

End Sub

Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove

If e.Button = MouseButtons.Left Then
Me.Left = Me.Left + (e.X - m_x)
Me.Top = Me.Top + (e.Y - m_y)
End If

End Sub
