在 VB.NET 中 SetWindowPos 应如何使用?
因为数据类型的不同,VB.NET调用系统API函数和VB6不太一样,肢孝颤VB6是这样:
Public Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal 慎山Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
在VB.NET中是这样调用:
DllImport("历败user32.dll", SetLastError:=True) _
Public Shared Function SetWindowPos(ByVal hWnd As IntPtr, ByVal hWndInsertAfter As IntPtr, ByVal X As Integer, ByVal Y As Integer, ByVal cx As Integer, ByVal cy As Integer, ByVal uFlags As SetWindowPosFlags) As Boolean
End Function

注意:参数顷困为动态雀明念数槐春组;
Private Function MyF(ByRef d() As Integer)
ReDim d(4, 13) As Integer
Dim i As Integer
Dim j As Integer
Dim n As Integer
Dim MyNum(4) As Integer
For i = 1 To 4
MyNum(i) = 0
Next i
Randomize
For i = 1 To 4
For j = 1 To 13
n = Int(Rnd * 4 + 1)
Do While MyNum(n) = 13
n = Int(Rnd * 4 + 1)
Loop
d(i, j) = n
MyNum(n) = MyNum(n) + 1
Next j
Next i
End Function
