Yes, but how can i get a handler of the string? SetClipboardData demands handler, yet i have only an address.

Reading the API documentation will take you a long way in getting it done.
Once SetClipboardData is called, the system owns the object identified by the hData parameter. The application can read the data, but must not free the handle or leave it locked. If the hData parameter identifies a memory object, the object must have been allocated using the GlobalAlloc function with the GMEM_MOVEABLE and GMEM_DDESHARE flags.MSDN website is a great tool as well.

So i should alocate some memory, copy data and pass the handlet to SetClipboardData? Ok, i'll give it a try. Thanks.

Read The Fine Manual is a cliché. 

Just remember to have the right format of data in the target of the data handle.

If it's an editbox, send it WM_COPY.

The thing is, i don't have a window at all. I even open clipboard with zero handler. But thanks anyway.

Then as mentioned in previous posts, use OpenClipboard, and SetClipboardData. If you need some help with these, see Using the Clipboard (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/dataexchange/clipboard/usingtheclipboard.asp) on MSDN.
