How can I move A Form That Has No Title Bar ?

The WM_NCLBUTTON message is generated by Windows when a user right-clicks on a window's title bar. Windows uses this message to determine whether the window should be moved by further user actions. If the title bar does not exist, this message is not generated. However, it is often useful to move a window when it doesn't have a title bar. A window or form in 32-bit Visual
Basic will not have a title bar under the following circumstances:

Visual Basic 4.0

Visual Basic 5.0

Caption = ""

Caption = ""

ControlBox = False

ControlBox = False

MaxButton = False

MinButton = False

The sample code below illustrates a way of letting users move a form without a title bar by simply clicking and dragging it from anywhere on the form. The code placed in the MouseMove event procedure of Form1 may be placed in other event procedures, if so desired. For example, the code
could be placed in the MouseDown event procedure of a Label control allowing movement of the form by selecting and dragging from the Label control.

NOTE: In Visual Basic 4.0, a form with a menu will have the title bar supplied by default so the method demonstrated below is not necessary. In Visual Basic 5.0, a form with a menu will not have a title bar supplied by default.

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
Private Declare Sub ReleaseCapture Lib "User32" ()
Private Sub Form_Load()
Command1.Caption = "Exit"
End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim lngReturnValue As Long

If Button = 1 Then
Call ReleaseCapture
lngReturnValue = SendMessage(Me.hWnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&)
End If
End Sub
Private Sub Command1_Click()
End Sub
