从Delphi（Win32）设置环境变量 [英] Set environment variables from Delphi (Win32)

问题描述

我正在尝试从我的delphi应用程序中设置一个系统的环境变量。文档说要向HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment添加一个注册表项，然后广播WM_SETTINGCHANGE消息。任何人知道如何广播此消息？

PS。我试图在控制台应用程序中执行此操作。

解决方案

在Embarcadero开发人员网络中还有一个涵盖此问题的主题并提供用于发送消息的示例代码。作者使用 SendMessageTimeout 根据 WM_SETTINGCHANGE的MSDN文档中的建议 ：

I'm trying to set a system wide environment variable from within my delphi application. The Documentation says to add a registry key to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment and then broadcast a WM_SETTINGCHANGE message. Anyone know how to Broadcast this message?

PS. I'm trying to do this in a console application.

解决方案

There is also a topic in the Embarcadero Developer Network covering this issue and providing sample code for sending the message. The author uses SendMessageTimeout as recommended in the MSDN doc for WM_SETTINGCHANGE:
