用易语言实现斐波那契数列

用易语言实现斐波那契数列，可以使用以下代码：//初始化变量
m_nList[0] = 0
m_nList[1] = 1//使用循环来实现斐波那契数列
For i = 2 To 10
m_nList[i] = m_nList[i-1] + m_nList[i-2]
Next//输出斐波那契数列
For i = 0 To 10
Print m_nList[i]
Next

用易语言实现获取窗口句柄

获取窗口句柄可以使用Windows API函数FindWindow或FindWindowEx。以下是用易语言实现获取窗口句柄的示例代码：

' 引入Windows API函数
Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As Any, ByVal lpWindowName As Any) As Long
Declare Function FindWindowEx Lib "user32.dll" Alias "FindWindowExA" (ByVal hwndParent As Long, ByVal hwndChildAfter As Long, ByVal lpClassName As Any, ByVal lpWindowName As Any) As Long

' 查找指定窗口标题的顶级窗口句柄
Function FindTopLevelWindow(ByVal Title As String) As Long
    FindTopLevelWindow = FindWindow(vbNull, StrPtr(Title))
End Function

' 查找指定父窗口和窗口标题的子窗口句柄
Function FindChildWindow(ByVal ParentHwnd As Long, ByVal ClassName As String, ByVal Title As String) As Long
    FindChildWindow = FindWindowEx(ParentHwnd, 0, StrPtr(ClassName), StrPtr(Title))
End Function

' 示例用法
Sub Main()
    Dim hWnd As Long
    ' 查找记事本主窗口句柄
    hWnd = FindTopLevelWindow("无标题 - 记事本")
    If hWnd <> 0 Then
        ' 查找记事本编辑框子窗口句柄
        hWnd = FindChildWindow(hWnd, "Edit", vbNullString)
        If hWnd <> 0 Then
            MsgBox "找到编辑框句柄：" & hWnd
        Else
            MsgBox "未找到编辑框句柄"
        End If
    Else
        MsgBox "未找到记事本主窗口句柄"
    End If
End Sub

上述代码中，FindWindow函数用于查找顶级窗口句柄，FindWindowEx函数用于查找子窗口句柄。函数的参数lpClassName和lpWindowName分别表示窗口类名和窗口标题，可以通过vbNull或vbNullString表示为空。StrPtr函数用于将字符串转换为指向该字符串的指针，以便传递给API函数。

用易语言 实现 拖拽取窗口句柄 代码

以下是用易语言实现拖拽取窗口句柄的代码：

'窗口句柄
Dim hWnd As Long

'鼠标按下事件
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    '按下左键
    If Button = 1 Then
        '取得窗口句柄
        hWnd = GetCapture()
        '设置鼠标捕获
        SetCapture(Me.hWnd)
    End If
End Sub

'鼠标移动事件
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    '如果有鼠标捕获
    If hWnd <> 0 Then
        '移动窗口
        SendMessage(hWnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&)
    End If
End Sub

'鼠标松开事件
Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    '释放鼠标捕获
    ReleaseCapture
    '清空窗口句柄
    hWnd = 0
End Sub

这段代码实现了在窗口上按下鼠标左键后，可以拖拽窗口并获取窗口句柄。需要注意的是，此代码只适用于拖拽窗口标题栏获取窗口句柄，如果需要获取其他窗口句柄，需要修改相应的参数。
