无法从沙盒进程发送消息 [英] Cannot send message from a Sandbox process

问题描述

I have a C++ project which sets up a global hook. From the hook procedure, I send some data to my application using SendMessage (WM_COPYDATA) api.

在以下环境中测试应用程序时发现一个问题:

I find out a problem when I test my application on following environments:

1. Vista中的IE7(保护模式)

1. IE7 (Protected mode) in Vista

2. Office内容(版本10)处于受保护的模式.

2. Office content (version 10) in protected mode.

3. Adobe Reader 10(保护模式)

3. Adobe Reader 10 (protected mode)

到目前为止，我知道，如果应用程序在低完整性进程中运行，并且从应用程序发送到较高完整性进程的窗口的消息将被UIPI阻止.我跟随MSDN使用ChangeWindowMessageFilter.但是，它只能解决#1问题. 从Adobe网站上，我知道它使用与Office 10相同的技术来开发保护模式.

So far, I know that if an application is run in low integrity process and the message sent from it to a window of a higher integrity process will be blocked by UIPI. I follow MSDN to use ChangeWindowMessageFilter. However, it only solve #1 issue. From Adobe website, I know that it uses the same technique as Office 10 to develop the protected mode.

请注意，Spy ++在Adobe Reader 10保护模式下工作良好.我不知道Spy ++的详细功能，但我想它在记录消息时使用了挂钩技术.

Note that the Spy++ work wells for Adobe Reader 10 protected mode. I don't know what the Spy++ does in detail, but I guess it uses hooking technique in logging message.

有人可以对我的问题有任何建议吗?如果我无法将SendMessage用于Adobe Reader 10，应该使用哪种进程间通信?

Could anyone have any advice on my issue? If I cannot use SendMessage for Adobe Reader 10, which interprocess communication should I use?

推荐答案

能否请您提供有关SendMessageEX api的更多信息?我在互联网上搜索，并在为 Dynamics AX指定的WinAPI类中找到此函数2009  and 动态 AX 4.0 .我不知道该怎么用.请帮忙.

Could you please give more information about SendMessageEX api? I search on internet and find out this function in WinAPI class specified for Dynamics AX 2009 and Dynamics AX 4.0. I don't know how to use it. Please help.
