Does anyone know about "MSUIM.Msg.Private"?

[fitatc]

I can't find any refrence any where(like this website, google, wiki). :( -----------------How I found it------------------------------------------- It's a Window's string message(0xC000 through 0xFFFF). I got this from my [MFC Dialogbased Program]: create a new [MFC Dialogbased Program], put a breakpoint here: thrdcore.cpp

BOOL AFXAPI AfxInternalPumpMessage()
{
_AFX_THREAD_STATE *pState = AfxGetThreadState();

if (!::GetMessage(&(pState->m\_msgCur), NULL, NULL, NULL)) //●

Do nothing but start you program, you will get a message over 0xC000. Use spy++ or GetClipboardFormatName you will get "MSUIM.Msg.*" //* may be Private
