你可以使用Windows API函数来获取窗口名称,具体可以使用以下步骤:
1. 使用`FindWindow`函数查找窗口句柄,该函数的输入参数是窗口类名和窗口名称,输出参数是窗口句柄。
2. 使用`GetWindowTextLength`函数获取窗口名称的长度,该函数的输入参数是窗口句柄,输出参数是窗口名称的长度。
3. 使用`GetWindowText`函数获取窗口名称,该函数的输入参数是窗口句柄、输出参数是窗口名称和名称长度。
下面是一个示例代码,可以获取指定窗口的窗口名称:
```vb.net
Imports System.Runtime.InteropServices
Public Class Form1
Private Declare Auto Function FindWindow Lib "user32.dll" (ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr
Private Declare Auto Function GetWindowTextLength Lib "user32.dll" (ByVal hWnd As IntPtr) As Integer
Private Declare Auto Function GetWindowText Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal lpString As System.Text.StringBuilder, ByVal nMaxCount As Integer) As Integer
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim hwnd As IntPtr = FindWindow(Nothing, "窗口名称") '替换为你想要查找的窗口名称
If hwnd <> IntPtr.Zero Then
Dim length As Integer = GetWindowTextLength(hwnd)
If length > 0 Then
Dim sb As New System.Text.StringBuilder(length + 1)
GetWindowText(hwnd, sb, sb.Capacity)
Dim windowTitle As String = sb.ToString()
MessageBox.Show(windowTitle)
End If
End If
End Sub
End Class
```
这段代码使用了`System.Runtime.InteropServices`命名空间,其中声明了`FindWindow`、`GetWindowTextLength`和`GetWindowText`三个Windows API函数,然后在按钮点击事件中通过调用这些函数获取指定窗口的窗口名称,并在消息框中显示出来。
