如何检查OleInitialize是否已被调用？ [英] How to check if OleInitialize has already been called?

问题描述

我想写一个Delphi函数来注册一个dll。我希望该函数检查OleInitialize是否已经被调用之前，它这样做。我想我想避免初始化两次的后果，因为我不知道他们可能是什么。我担心我的函数不能像regsvr32.exe那样处理各种各样的dll。

I want to write a Delphi function to register a dll. I want the function to check if OleInitialize has already been called before it does so. I guess I'm trying to avoid the consequences of initializing twice because I'm not sure what they might be. I'm worried that my function won't handle as wide a variety of dlls as regsvr32.exe.

推荐答案

文档：

返回值

[...]

S_FALSE - COM库已在此公寓上初始化。

Return Value
[...]
S_FALSE - The COM library is already initialized on this apartment.

...

通常，COM库仅在公寓中初始化一次。后续调用将成功，只要它们不尝试更改公寓的并发模型，但会返回 S_FALSE 。
