vb2008 获取窗口标题的问题

' .NET 的数据类型和 VB6 的完全不同。API 声明也完全不一样。

Private Declare Function WindowFromPoint Lib "user32" Alias "WindowFromPoint" (ByVal xPoint As Integer, ByVal yPoint As Integer) As IntPtr

Private Declare Function GetWindowTextLength Lib "user32" Alias "GetWindowTextLengthA" (ByVal hwnd As IntPtr) As Integer

Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As IntPtr, ByVal lpString As String, ByVal cch As Integer) As Integer

Private Structure TitleEXD

VBFixedString(255) Public Text As String

End Structure

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim x As Integer = MousePosition.X, y As Integer = MousePosition.Y, res As String

Label1.Text = "鼠标当前坐标:" x "," y

Dim hwnd As IntPtr = WindowFromPoint(x, y)

Label2.Text = "句柄:" hwnd.ToString()

Dim Tlong As Integer = GetWindowTextLength(hwnd) Mod 65536 + 1

Dim TitleE As TitleEXD

TitleE.Text = Space(255)

Dim dlld As Integer = GetWindowText(Me.Handle, TitleE.Text, Tlong) Mod 65536

Label3.Text = "窗口标题:" TitleE.Text

If dlld = 0 Then

res = "失败"

Else

res = "成功"

End If

Label4.Text = "获取标题" res

End Sub

vb点虐 ,知道一个窗口的标题,窗口正在运行,如何使程序在该窗口关闭时Msgbox"窗口已关闭"

利用Process类遍历当前所有进程,利用MainWindowTitle属性来获取指定窗口标题的进程ID,创建一个线程池或者线程,来循环检测这个ID的进程是否已退出,在循环线程中设置Thread.Sleep(50)中断来减少系统开销,这个方法仅适用于主窗口,也就是窗体关闭,程序就退出了,如果针对的是子窗口,就用第二种方法。

利用系统API,循环遍历所有窗口,当指定标题不存在时就是已经退出了。
