Clipboard.GetDataObject need singleton #20
Description
If Hook WM_DRAWCLIPBOARD Multiple Process
Hook event is good work Data is Empty. -_- ( It's Sometime )
( WM_CLIPBOARDUPDATE is Same Trouble )
( I tried Global Mutex Control Critical Section = Same Trouble)
( I Think Just One Process and need IPC Communication )
It's OS Stupid But we need Solve that...
and we need use WM_CLIPBOARDUPDATE if over Windows Vista....
if WM_DRAWCLIPBOARD Die about Chain Clipboard is Stupid ( About Another Process )
it's My dirty Code....
( Warning : My english is not good...)
