Move a form with no border

Works for anything else you specify, like say a tab control, pic box etc.

VB Code:

Private OldX As Integer
Private OldY As Integer
Private DragMode As Boolean
Dim MoveMe As Boolean
 
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
 
    MoveMe = True
    OldX = X
    OldY = Y
 
End Sub
 
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
 
    If MoveMe = True Then
        Me.Left = Me.Left + (X - OldX)
        Me.Top = Me.Top + (Y - OldY)
    End If
 
End Sub
 
Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
 
    Me.Left = Me.Left + (X - OldX)
    Me.Top = Me.Top + (Y - OldY)
    MoveMe = False
 
End Sub

There is an API way. I'll look for it...

Here it is :

VB Code:

Option Explicit 
 
Private Declare Function ReleaseCapture Lib "user32" () As Long 
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long 
 
Const WM_NCLBUTTONDOWN As Long = &HA1 
Const HTCAPTION As Long = 2 
 
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single) 
   Dim lngReturnValue As Long 
   If Button = vbLeftButton Then 
       Call ReleaseCapture 
       lngReturnValue = SendMessage(Me.hwnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&) 
   End If 
End Sub
