</Br>
我想用BroadcastSystemMessage来在两个进程之间通讯,我从一个进程发送了一个用RegisterWindowMessage注册过的消息,但在目的进程中却没有收到该消息.<Br>
</Br>
我认为你应该在两个进程的最高级窗口中都注册该消息.请看下例:<Br>
</Br>
static UINT sBroadcastCommand = ::RegisterWindowMessage( _T("BroadcastCommand"));<Br>
</Br>
BEGIN_MESSAGE_MAP( Gui_Top_Level_MainFrame, Gui_MainFrame )<Br>
ON_REGISTERED_MESSAGE( sBroadcastCommand, onBroadcastCommand )<Br>
END_MESSAGE_MAP()<Br>
</Br>
LRESULT Gui_MainFrame :: onBroadcastCommand( UINT aMsg, LPARAM lParam )<Br>
{<Br>
your code...<Br>
}<Br>
然后发送进行应该包含:<Br>
While the sending process would contain:<Br>
</Br>
static UINT sBroadcastCommand = ::RegisterWindowMessage( _T("BroadcastCommand"));<Br>
</Br>
void Someclass :: someMethod( void )<Br>
{<Br>
::PostMessage( (HWND)HWND_BROADCAST,<Br>
sBroadcastCommand, 0,<Br>
yourMessageId );<Br>
}<Br>
</Br>
</p></td></tr>
