Hi, I couldn't get u what u actually u r expecting Ok anyway. herewith i am sending some Procedures of script which is concern about the Resizing the form ,along with which will resize the controls accorindly.


Public Sub ResizeForm(pfrmIn As Form)

Dim FormControl As Control
Dim isVisible As Boolean
Dim StartX, StartY, MaxX, MaxY As Long
Dim bNew As Boolean

If Not bRunning Then
bRunning = True

If FindForm(pfrmIn) < 0 Then
bNew = True
Else
bNew = False
End If


If pfrmIn.Top < 30000 Then
isVisible = pfrmIn.Visible
On Error Resume Next

If Not pfrmIn.MDIChild Then
On Error GoTo 0
' ' pfrmIn.Visible = False
Else

If bNew Then
StartY = pfrmIn.Height
StartX = pfrmIn.Width
On Error Resume Next

For Each FormControl In pfrmIn

If FormControl.Left + FormControl.Width + 200 > MaxX Then
MaxX = FormControl.Left + FormControl.Width + 200
End If


If FormControl.Top + FormControl.Height + 500 > MaxY Then
MaxY = FormControl.Top + FormControl.Height + 500
End If


If FormControl.X1 + 200 > MaxX Then
MaxX = FormControl.X1 + 200
End If


If FormControl.Y1 + 500 > MaxY Then
MaxY = FormControl.Y1 + 500
End If


If FormControl.X2 + 200 > MaxX Then
MaxX = FormControl.X2 + 200
End If


If FormControl.Y2 + 500 > MaxY Then
MaxY = FormControl.Y2 + 500
End If

Next FormControl

On Error GoTo 0
pfrmIn.Height = MaxY
pfrmIn.Width = MaxX
End If

On Error GoTo 0
End If


For Each FormControl In pfrmIn
ResizeControl FormControl, pfrmIn
Next FormControl

On Error Resume Next

If Not pfrmIn.MDIChild Then
On Error GoTo 0
pfrmIn.Visible = isVisible
Else

If bNew Then
pfrmIn.Height = StartY
pfrmIn.Width = StartX

For Each FormControl In pfrmIn
ResizeControl formControl, pfrmIn
Next FormControl
End If
End If
On Error GoTo 0
End If
bRunning = False
End If
End Sub

Else
inControl.Move lLeft, lTop, lWidth, lHeight
inControl.Move lLeft, lTop, lWidth
inControl.Move lLeft, lTop
End If

End Sub

*****************

Private Function FindControl(inControl As Control, inName As String) As Long

Dim i As Long
FindControl = -1

For i = 0 To (MaxControl - 1)

If ControlRecord(i).Parrent = inName Then

If ControlRecord(i).Name = inControl.Name Then
On Error Resume Next

If ControlRecord(i).Index = inControl.Index Then
FindControl = i
Exit Function
End If

On Error GoTo 0
End If

End If

Next i

End Function

If u have any doubt feel free to ask me..

I'm assuming you want a Form that has no Border, Caption, etc..

In a Form with BorderStyle Set to Sizeable and ShowInTaskBar set to False and WindowState set to Maximized..

Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
Private Const GWL_STYLE = (-16)
Private Const WS_CAPTION = &HC00000
Private Const WS_BORDER = &H800000

Private Sub Form_Load()
'A Maximized Sizable Form doesn't Cover the Taskbar
'So Just Remove the Caption and Border..
Call SetWindowLong(hwnd, GWL_STYLE, GetWindowLong(hwnd, GWL_STYLE) Xor WS_CAPTION Xor WS_BORDER)
End Sub
