Question

我的电脑上有一个应用程序。我可以获得该应用程序的每个细节（句柄，主窗口等）

该应用程序有很多标签，我想在我自己的应用程序中读取该标签和msgbox字符串。

你可以尝试这个（pinvoke很好地涵盖了）：

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Private Shared Function GetWindowText(ByVal hwnd As IntPtr, ByVal lpString As StringBuilder, ByVal cch As Integer) As Integer
End Function

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Private Shared Function GetWindowTextLength(ByVal hwnd As IntPtr) As Integer
End Function

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button2.Click
  Dim length As Integer = GetWindowTextLength(otherAppLabelHandle)
  Dim sb As New StringBuilder(length + 1)
  GetWindowText(otherAppLabelHandle, sb, sb.Capacity)
  MessageBox.Show(sb.ToString())
End Sub

从不同的应用程序中读取标签中的文本
