I am guessing you are talking about a status bar at the bottom of the dialog you are working on.

These can't be moved from their location at the bottom of the window.

If this isn't what you're talking about, post some code and the names of the controls you are using.

I guess you mean you are creating your own control which you want to use to replace the window's caption bar. You want to allow the user to move the form by clicking and dragging on this control - right ?

This article on vbnet should be exactly waht you need :

I've already answered this in a similiar question: http://www.experts-exchange.com/jsp/qShow.jsp?ta=visualbasic&qid=10246157  


Here is the answer from that question. It talks about using a picturebox to do what you want... Instead of doing the picturebox, use the MouseMove event in your control:

I've turned the ordinary titlebar off in my app (borderstyle = None) and I've made my own more graphical layout. Now I want to make it possible for the user to click my own titlebar and drag the whole form just like they could before. I'm having problem with the mousemove event. I know there is very little code to solve this but my brain doesn't function right now! The control to use for the bar could be a picture, Image or some control that can be invisible (background sees through) but still work.

Put a picturebox on the form called "Picture1" then add the following code to the DECLARATIONS SECTION of the form.

You can put the picture box a the top of the form and size it as if it were a title bar...  Color it if you want...

'--------------------------------------------------
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" ()
Const WM_NCLBUTTONDOWN = &HA1
Const HTCAPTION = 2
Private Sub Picture1_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(Form1.hWnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&)
   End If
End Sub
'--------------------------------------------------

Run the program... When you put your mouse over the picturebox, click and hold the left mouse button and drag the form....

Another API Solution.. (not as pretty as mcrider's tho.. <sigh>).. Followed by a TIP.. <smile>.

<----- Begin DECLARATIONS SECTION ----->

Private Type PointApi
    X As Long
    Y As Long
End Type

Private Declare Function ClientToScreen Lib "user32" _
    (ByVal hwnd As Long, lpPoint As PointApi) _
    As Long

Private Declare Function ReleaseCapture Lib "user32" _
    () _
    As Long

Private Declare Function SetCapture Lib "user32" _
    (ByVal hwnd As Long) _
    As Long

Private msngLastX As Single
Private msngLastY As Single
Private msngThisX As Single
Private msngThisY As Single
Private mudtPoint As PointApi

<----- End DECLARATIONS SECTION ----->


<----- Begin CODE SECTION ----->

Private Sub UserControl1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = vbLeftButton _
    Then
        Dim lngReturn As Long
        lngReturn = SetCapture(UserControl1.hwnd)
        mudtPoint.X = X / Screen.TwipsPerPixelX
        mudtPoint.Y = Y / Screen.TwipsPerPixelY
        lngReturn = ClientToScreen(UserControl1.hwnd, mudtPoint)
        msngLastX = mudtPoint.X * Screen.TwipsPerPixelX
        msngLastY = mudtPoint.Y * Screen.TwipsPerPixelY
    End If
End Sub

Private Sub UserControl1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = vbLeftButton _
    Then
        Dim lngReturn As Long
        mudtPoint.X = X / Screen.TwipsPerPixelX
        mudtPoint.Y = Y / Screen.TwipsPerPixelY
        lngReturn = ClientToScreen(UserControl1.hwnd, mudtPoint)
        msngThisX = mudtPoint.X * Screen.TwipsPerPixelX
        msngThisY = mudtPoint.Y * Screen.TwipsPerPixelY
        Form1.Move _
           Form1.Left + (msngThisX - msngLastX), _
           Form1.Top + (msngThisY - msngLastY), _
           Form1.Width, _
           Form1.Height
        msngLastX = msngThisX
        msngLastY = msngThisY
    End If
End Sub

Private Sub UserControl1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = vbLeftButton _
    Then
        Dim lngReturn As Long
        lngReturn = ReleaseCapture
    End If
End Sub

<----- End CODE SECTION ----->

TIP: To get the Height of a standard Caption use the GetSystemMetricsInfo API..

Private Declare Function GetSystemMetrics Lib "user32" _
(ByVal nIndex As Long) _
As Long
Private Const SM_CYCAPTION = 4          ' Height of caption or title

lngCaptionHeightExpressedInPixels = _
    GetSystemMetrics(SM_CYCAPTION)
