我正在使用以下代码单击一个按钮以显示另一个要单击的表单：

Dim hwnd As Integer = FindWindow(vbNullString, "Virtual CDRom Control Panel")
Dim x As Integer = FindWindowEx(hwnd, 0, vbNullString, "Driver Control ...")

SendMessage(x, BM_CLICK, 0&, 0&)
Thread.Sleep(200)
hwnd = FindWindow(vbNullString, "Virtual CD-ROM Driver Control")
Debug.Print(hwnd)

问题是当它到达

发送消息（x，BM_CLICK，0&，0&）

点击按钮，它会在那里停止代码，直到我退出弹出的框。从下一行开始，我希望能够继续而不必退出该框

hwnd = FindWindow(vbNullString, "虚拟光驱驱动控制")

找到弹出窗口，然后单击该框内的按钮。

任何帮助都会很棒！:o)

尝试更改SendMessage为PostMessage.

另请注意，所有HWNDs 必须声明为IntPtr。
也wParam和lParam为SendMessage和PostMessage是IntPtrs。
这将使您的代码与 x64 环境兼容。
