是否可以从32位应用程序访问64位dll？ [英] Is it possible to access a 64-bit dll from a 32-bit application?

问题描述

我有一个类似于 Taskbar Shuffle 的Delphi应用程序，其中包含一个hook dll。 / p>

编辑：此钩子DLL通过发送Windows消息与主应用程序通信。

我想添加对XP和Vista x64的支持，我的初始想法是将dll转换为64位（使用FreePascal进行编译），但现在应用程序为32位（Delphi）。

32位应用程序是否可以访问64位dll？

EDIT2 ：I通过LoadLibrary来加载dll，所以我想我被卡住了，因为32位进程将无法加载一个64位的dll，根据我在Lars Truijens指出的链接上的一个答案

解决方案

否。您必须编译两个版本：64位和32位。

I have a Delphi application similar to Taskbar Shuffle that includes a hook dll.

EDIT: This hook DLL communicates with the main app by sending windows messages.

I want to add support to XP and Vista x64 and my initial idea was to convert the dll to 64-bit (compiling it with FreePascal) but keep the application 32-bit for now (Delphi).

Is it possible for a 32-bit application to access a 64-bit dll?

EDIT2: I'm loading the dll via LoadLibrary so I guess I'm stuck since a 32-bit process won't be able to load a 64-bit dll, according with what I read on the link pointed by Lars Truijens on one of the answers below.

解决方案

No. You'll have to compile two versions: 64-bit and 32-bit.
