你可以使用以下代码来打开软件并获取该软件窗体的句柄:
```
'引用 Windows API
Imports System.Runtime.InteropServices
Public Class Form1
'定义 API 函数
Private Declare Auto Function FindWindow Lib "user32.dll" (ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
'打开软件
Process.Start("C:\Program Files\YourSoftware\YourSoftware.exe")
'等待软件启动
Threading.Thread.Sleep(5000)
'查找窗口
Dim hWnd As IntPtr = FindWindow(Nothing, "YourSoftwareTitle")
If hWnd <> IntPtr.Zero Then
'获取窗体的句柄
Dim hChildWnd As IntPtr = FindWindowEx(hWnd, IntPtr.Zero, "YourClassName", "YourWindowName")
If hChildWnd <> IntPtr.Zero Then
'在此处可以对窗体进行操作
End If
End If
End Sub
End Class
```
在代码中,你需要将 `YourSoftware` 替换为你要打开的软件的安装路径,将 `YourSoftwareTitle` 替换为你要打开的软件的窗口标题,将 `YourClassName` 替换为你要获取的窗体的类名,将 `YourWindowName` 替换为你要获取的窗体的标题。如果要获取主窗口的句柄,则将 `hChildWnd` 的参数设置为 `IntPtr.Zero`。
