Hi,
When upgrading api calls look at the msdn documentation. If a
parameter is in use byval, out use byref. The new integer is the same as
the old long. Callback functions are now delegate. The old integer is the
same as the new short. Window handles hwnd are now given as intptr.
Declare Function SHAppBarMessage Lib "shell32.dll" Alias "SHAppBarMessage" _
(ByVal dwMessage As Integer, ByRef pData As APPBARDATA) As Integer
Structure APPBARDATA
Dim cbSize As Integer
Dim hwnd As IntPtr
Dim uCallbackMessage As [Delegate]
Dim uEdge As Integer
Dim rc As Rect
Dim lParam As Integer ' message specific
End Structure
Structure RECT
Dim Left As Integer
Dim Top As Integer
Dim Right As Integer
Dim Bottom As Integer
End Structure
Const ABS_AUTOHIDE = &H1
Const ABS_ONTOP = &H2
Const ABM_GETSTATE = &H4
Const ABM_GETTASKBARPOS = &H5
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Dim abd As APPBARDATA
Dim ret As Integer
abd.hwnd = Me.Handle
SHAppBarMessage(ABM_GETTASKBARPOS, abd)
ret = SHAppBarMessage(ABM_GETSTATE, abd)
If (ret And ABS_AUTOHIDE) Then Debug.WriteLine("Autohide option is on")
If (ret And ABS_ONTOP) Then Debug.WriteLine("Always on top option is on")
Dim strOut As String
strOut = String.Format("Coordinates are ({0}, {1}) - ({2}, {3})", _
abd.rc.Left, abd.rc.Top, abd.rc.Right, abd.rc.Bottom)
Debug.WriteLine(strOut)
End Sub
