关于检测一个程序是否打开的代码~~高手赐教~~
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
  Private Declare Function GetWindowThreadProcessId Lib "user32" (ByVal hwnd As Long, ByVal lpdwProcessId As Long) As Long

  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  Dim a As Long
  a = FindWindow(vbNullString, "帮助")
  If a <> 0 Then
  Label1.Text = "己运行"
  Else
  Label1.Text = "己关闭"
  End If
  End Sub


这个是我网上找来的关于检测一个程序是否开启的代码...但是貌似是VB6的...不知道VB.NET怎么写？？？高手赐教！

不过应该把Long都改成UInt32。
