VB.Net 3.5 Windows - 如何获取进程用户对象计数

发布于 2024-09-09 06:34:02 字数 232 浏览 1 评论 0原文

任何人都可以告诉我如何获取当前进程的“用户对象”的当前计数（如任务管理器中所示）。

我了解如何使用以下方法获取句柄计数：

Process.GetCurrentProcess.HandleCount

但是我们的应用程序只需打开特定表单的 17 个实例就可以达到 10,000 个 USER 对象计数，因此我们想尝试在用户达到限制之前警告用户资源正在变少和应用程序炸弹。

原文

Can any one please advise me how I can get the current count of "USER Object"s (as shown in task manager) for the current process.

I see how to get the handle count using:

Process.GetCurrentProcess.HandleCount

But our application can reach a USER Object count of 10,000 just by opening 17 instances of a particular form so we would like to try and warn a user that resources are getting low before they reach the limit and the application bombs.

如果我正在考虑正确类型的用户对象，您可以使用 GetGuiResources API函数。请参阅此处获取 C# 示例（第二个发送 1 作为标志的）。

下面是代码的 VB 翻译：

Imports System.Runtime.InteropServices

<DllImport("User32")> _
Public Shared Function GetGuiResources(ByVal hProcess As IntPtr, ByVal uiFlags As Integer) As Integer
End Function

Public Shared Function GetGuiResourcesUserCount() As Integer
    Return GetGuiResources(Process.GetCurrentProcess().Handle, 1)
End Function

If I'm thinking of the right kinds of user objects you can do it with the GetGuiResources API function. See the pinvoke page for it here for a C# sample (the second one that sends in 1 as the flag).

Here's a VB translation of the code:

Imports System.Runtime.InteropServices

<DllImport("User32")> _
Public Shared Function GetGuiResources(ByVal hProcess As IntPtr, ByVal uiFlags As Integer) As Integer
End Function

Public Shared Function GetGuiResourcesUserCount() As Integer
    Return GetGuiResources(Process.GetCurrentProcess().Handle, 1)
End Function
