Gennemsigtige vinduer...

Der skal du have fat i nogle API kald. CreateRectRgn eller sådan noget.

http://www.vbapi.com/ref/c/createroundrectrgn.html

der kan du bl.a læse om denne API samt de fleste andre.

kik lidt på planetsourcecode.com .........har set nogle fede samples derinde!

CreateRectRgn kan nemt laves sådan:

\'----------------------------------------------- (Form Kode) -----------------------------------------------

\'----------------------------------- CreateRectRgn ------------------------------------
\'Start med at lave et bitmap billed, eks: hvid baggrund og en sort cirkel
\'åbne billedet i \"Form Picture\" og set \"Form BorderStyle\" til \"0 - None\"
\'nu skulle du få en sort cirkel når du køre dit program
\'----------------------------------- CreateRectRgn ------------------------------------

\'--------- CreateRectRgn ---------
Private Sub Form_Load()
    If hRgn Then DeleteObject hRgn
\'------------------------------------ Fjern farve -------------------------------------
\'Her kan man lave en anden baggrunds farve hvis man bruger en hvid farve i sit billed
\'html farvekode \"#000000\" \"-#\" \"+&H\" \"=&H000000\" fjerner alt det sorte i billedet
\'Paint Shop Pro kan nemt bruges til at finde farvekoden.
    hRgn = GetBitmapRegion(Me.Picture, &HFFFFFF)
\'------------------------------------ Fjern farve -------------------------------------
    SetWindowRgn Me.hwnd, hRgn, True
End Sub
\'--------- CreateRectRgn ---------

\'--------- Move window ---------
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = vbLeftButton Then
    FormDrag Me
    End If
End Sub
\'--------- Move window ---------

\'--------- Exit button ---------
Private Sub Exit_button_Click()
    Unload Me
End Sub
\'--------- Exit button ---------
\'----------------------------------------------- (Form Kode) -----------------------------------------------


\'---------------------------------------------- (Module Kode) ----------------------------------------------
\'Koden her skal indtastes i et Module

Sorry sjh... Men jeg kom lige til at klikke lidt for hurtigt så jeg opretter et nyt spørgsmål ved navn \"Point til SJH\". Skriv et svar der og du får dine point...
