我正在寻找一种方法来执行 Steam（Steam.exe）并等待它被加载（不退出）。
我认为一个好主意是列出所有子句柄并在标题句柄中搜索一个字符串，因为当蒸汽加载存在一个名为“Friends”的窗口句柄时，但这对我来说很难（API）所以可能存在等待程序加载的简单方法...
我将要做什么的例子：
' First process
Process.start("Process 1.exe")
' Here will goes an efficient method to wait for application is loaded,
' not sleeping X seconds measuring the loading time or any of that.
' Second process
' Depends on first process fully loaded.
' If first process is not fully loaded (libraries and that) then this process can't run.
Process.start("Processs 2.exe")
更新：
主要问题是如何等待 X 进程被加载，但关于 Steam.exe 我也注意到，当 Steam 被加载时，我会尝试读取/打开一些 regkeys：

也许我可以用代码做一些事情来监控其中一个 RegKeys 是否被访问？
像这样的东西？：
Dim RegKey = "HKLM\...blablabla"
Process.start("steam.exe")
While not Regkey.IsAccessed
' Do nothing and wait
Loop
Process.start("Second process.exe")
更新 2：
我正在尝试通过引用 Amegon 的解决方案来制作一个函数，但我没有完成代码，因为我在一行中遇到了错误：
Memory = hprocess.PrivateMemorySize64
但是，当我尝试启动“大”应用程序（需要大量时间加载的应用程序，如 Photoshop）时，我只会收到错误消息，而“小”应用程序运行良好。
如果有人可以帮助我简化/改进 Amegon 的解决方案以制作通用函数并纠正内存溢出错误...谢谢！
这是我的代码：
