I. Text Content operations
The following code demonstrates how to copy text content to the clipboard:
Cstring source;// Save the text content in the source variableIf (openclipboard ()){Hglobal clipbuffer;Char * buffer;Emptyclipboard ();Clipbuffer = globalalloc (gmem_ddeshare, dource. getlength () + 1 );Buffer = (char *) globallock (clipbuffer );Strcpy (buffer, lpcstr (source ));Globalunlock (clipbuffer );Setclipboarddata (cf_text, clipbuffer );Close
This example demonstrates the process of placing a component (tedit) on the clipboard and taking it out (put it on a tpanel.
The method for placing a clipboard is a process: setcomponent (component to be placed );The method to retrieve is a function: getcomponent (specifying the owner and specifying the parent window): the handle of the component returned by the function.
