ocx->在Internet Explorer中运行?

因此，请检查运行此代码的进程的特权. (并尝试使用更高的权限)

我想问题是，某些安全问题，某些SendMessage无权发送消息.

更改流程权限或考虑完成用例"的其他方法.

ocx -> runs in Internet Explorer?

So check the privileges of the process which run this code. (and try with higher rights)

I guess the problem is, that some SendMessage has no rights to send the message for some security issues.

Alter the process rights or think about other ways to accomplish your "use case".
