如何确定当前过程中COM使用的内部HWND? [英] How do I determine the internal HWND used by COM in my current process?

问题描述

我想在过程中将消息直接发布到COM所拥有的HWND.如何获取COM在单线程公寓模式下使用的HWND?

I want to Post messages directly to the HWND that's owned by COM in my process. How do I get the HWND that COM is using in single-threaded-apartment mode?

推荐答案

尝试一下:

HWND prevWindow = NULL;
HWND hwnd;
for ( ;; )
{
    hwnd = FindWindowEx( HWND_MESSAGE, prevWindow, L"OleMainThreadWndClass", NULL );
    if ( !hwnd )
        break;

    if ( GetWindowThreadProcessId( hwnd, NULL ) == GetCurrentThreadId() )
        break;

    prevWindow = hwnd;


    WCHAR className[255];
    *className = 0;
    ::GetClassName( hwnd, className, 255 );
}

让我知道它是否有效.
