BorderStyle at runtime

How do I change the border style of a form during runtime?

You can't - it's read only !
All the API calls I looked at allow you to add borders / rectangles around a window, but I don't think there's any way you can set this ! :(

Why do you need this ?

Although the MSDN says so, but you can change the border style fo a form at run time. Just call the statement changing the borderstyle of the form repeatedly for 3-4 times, and it will change the border style. I have done this using the inbuilt BorderStyle property of vb.

Sorry, it didnt work. I need this to create a floating/docking toolbar window like in MS-Office and VB

Doesn't this work

Code:

---

'assuming that the initial BorderStyle was 2
Private Sub Command1_Click()
    Form1.BorderStyle = 0
    Form1.Refresh
End Sub

---

Click the Button 3 - 4 times one after the other.

It does not work. In VB5, it even gives an error, and in VB6, nothing happens. Ther must be an API call 4 this!:confused:

Strange, I had VB6 and it worked for me.

if you want the api to do it, here it is:

Code:

---

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

'choices For style

Const WS_SIZEBOX = &H40000 '2-sizeable
'don't have other consts

Private Sub Command1_Click()
    Dim curstyle As Long, newstyle As Long

    'retrieve the window style
    curstyle = GetWindowLong(Me.hwnd, GWL_STYLE)
   
    curstyle = curstyle Or WS_SIZEBOX
    'will make fixed single/fixed dialog windows sizeable

    'Set the New style
    newstyle = SetWindowLong(Me.hwnd, GWL_STYLE, curstyle)
    'refresh
    Me.Refresh
End Sub

but if you want a floating, docking toolbar, do it the windows way with a class avalible from www.vbaccelerator.com
