ChangeClipboardChain
CloseClipboard
CountClipboardFormats
EmptyClipboard
EnumClipboardFormats
GetClipboardData
GetClipboardFormatName
GetClipboardOwner
GetClipboardViewer
GetOpenClipboardWindow
GetPriorityClipboardFormat
IsClipboardFormatAvailable
OpenClipboard
RegisterClipboardFormat
SetClipboardData
SetClipboardViewer
先open 然后empty 然后把要放到clipboard的数据放到globalmemory里 然后 setclipboarddata最后 close
详细说明可以看msdn
