Question on: IsDialogMessage

Hello,

Can anyone tell when we need to use the function IsDialogMessage?
What is the different between Code 1 and Code 2?

Code 1:
---------
while(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
if(!IsDialogMessage(&msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}

Code 2:
---------
while(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}

Thanks!!
