vb.net洗牌函数 java洗牌函数
VB.net为什么取消了“lenb”“midb”这些函数，.net又如何通过变通方法来实现？

#include QAxObject
#include Windows.h
int main(int argc, char *argv[])
{
//OleInitialize(0);
//CoInitialize(0);
QCoreApplication a(argc, argv);
QAxObject *asdfg = new QAxObject("Excel.Application");
return a.exec();
}
VB.NET自定义函数
很简单，在end select前再多加一种情况case else return "XXXx",因为你只提供了0-9这10种情况
Public Function Zuhe(ByVal qa As String) As String
Select Case qa
Case "0"
Return "1"
Case "1"
Return "3"
Case "2"
Return "4"
Case "3"
Return "6"
Case "4"
Return "2"
Case "5"
Return "8"
Case "6"
Return "9"
Case "7"
Return "7"
Case "8"
Return "5"
Case "9"
Return "0"
Case else
Return "XXXX"
End Select
End Function
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，VB6是这样：
Public Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal 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("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
参考：
vb.net 编写一个函数
注意：参数为动态数组；
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
