Hi,
How to move a form without controlbox?

Help please ...

Thanks

control box?
u mean title bar?
using API files i think..

See if this helps.

'// paste in New Project and click to move Form.
'//-- Panel1 and PictureBox1 can be uncommented to use the same Events.
'//-- to use only a Panel, PictureBox, or any other control, just add the appropriate code for each event.
Public Class Form1

    Private allowCoolMove As Boolean = False
    Private myCoolPoint As New Point

    Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) _
                                         Handles Me.MouseDown ', Panel1.MouseDown, PictureBox1.MouseDown
        allowCoolMove = True '// enable move.
        myCoolPoint = New Point(Cursor.Position.X - Me.Location.X, Cursor.Position.Y - Me.Location.Y) '// get coordinates.
    End Sub

    Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) _
                                         Handles Me.MouseMove ', Panel1.MouseMove, PictureBox1.MouseMove
        If allowCoolMove = True Then
            Me.Location = New Point(Cursor.Position.X - myCoolPoint.X, Cursor.Position.Y - myCoolPoint.Y) '// set coordinates.
        End If
    End Sub

    Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) _
                                         Handles Me.MouseUp ', Panel1.MouseUp, PictureBox1.MouseUp
        allowCoolMove = False '// disable move.
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
    End Sub
End Class

Works fine but is there's other way to move like controlbox?

Set .WindowState of a Form to Maximized/Minimized/Normal?

Me.WindowState = FormWindowState.Maximized
