Hello, Thanks for checking out the thread , and hopefully someone can point me in the right direction....

Ok I have a form that I need to drag and the form im using i have themed.... so i try using the following code with no success.....

Code 
Dim drag As Boolean

    Dim mousex As Integer

    Dim mousey As Integer

    Private Sub PositronTheme2_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown

        drag = True

        mousex = Windows.Forms.Cursor.Position.X - Me.Left

        mousey = Windows.Forms.Cursor.Position.Y - Me.Top

    End Sub

    Private Sub PositronTheme2_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove

        If drag Then

            Me.Top = Windows.Forms.Cursor.Position.Y - mousey

I've just tested it on Positron theme, it moves fine. But to answer your question:

Declare the following:

Code 
Private cX, cY As Integer

Private Dragging As Boolean = False

MouseDown event:

Code 
Dragging = True

cX = e.X

cY = e.Y

MouseMove event:

Code 
If Dragging Then

      Me.Top = Me.Top + (e.Y - cY)

      Me.Left = Me.Left + (e.X - cX)

End If

MouseUp event:

Code 
Dragging = False

You'll want to make changes directly to the PositronTheme class. Otherwise you'll be using repetitive code over all of your themed forms.

I've coded up a simple form skin for you. Take these concepts and apply them to Pat Positron's theme.
