- The ClipStac API
- ===================
-
- You can use the API by registering the following messages via the
- Windows' RegisterMessage function.
-
- Please see the file CSAPI.H.
-
- Messages sent to ClipStac:
- --------------------------
-
- SendMessage(0xffff,WM_CLIPSTACREGISTER,your_hWnd,0L);
- Send this message to initiate a ClipStac conversation.
- hWnd = 0xffff
- msg = WM_CLIPSTACREGISTER
- wParam = your_hWnd
- lParam = 0L
-
- Send this message to 0xffff to broadcast the message to every desktop
- window. If ClipStac is running, it will respond by Posting the same
- message back to you with wParam=0, LOWORD(lParam)=ClipStac's hWnd, and
- HIWORD(lParam)=your hWnd.
-
- Beware, however, that this will also send a WM_CLIPSTACREGISTER to
- your own program, so check the lParam to filter this out.
-
- BOOL SendMessage(hWndClipStac,WM_CLIPSTACPUSH,0,0L);
- Pushes the current Clipboard contents onto the top of the Stack
- (ClipStack[0]), and returns TRUE if successful, FALSE if not
-
- BOOL SendMessage(hWndClipStac,WM_CLIPSTACPOP,index,0L);
- Pops the contents of ClipStack[index] off the Stack and into the
- Clipboard. The index should be a valid ClipStack index. Returns TRUE
- if successful, FALSE if not.
-
- int SendMessage(hWndClipStac,WM_CLIPSTACFIND,0,LPSTR);
- Finds the first stack item that contains LPSTR in its identifying info.
- If found, returns the index of that item, otherwise -1.
-
- LPSTR SendMessage(hWndClipStac,WM_CLIPSTACGET,index,0L);
- Returns the identifying info of a stack item from ClipStack[index]. The
- return value is LPSTR or NULL.
-
- void SendMessage(hWndClipStac,WM_CLIPSTACDEREGISTER,0,0L);
- Send this message when your program is about to terminate (or whenever
- you have finished using ClipStac's services) so that ClipStac will
- remove your hWnd from its internal list.
-
- int SendMessage(hWndClipStac,WM_CLIPSTACNUMITEMS,0,0L);
- Send this message to find out how many items are in ClipStac's list.
-
-
- Messages received from ClipStac:
- --------------------------------
-
- WM_CLIPSTACEXIT - ClipStac will send this message to your program if ClipStac
- is about to terminate, provided that you previously registered yourself
- with WM_CLIPSTACREGISTER.
-
- WM_CLIPSTACREGISTER - ClipStac will post this message to your program if
- your program first sends the same message with its hWnd as the wParam.
- ClipStac's reply will have wParam=0, LOWORD(lParam)=ClipStac's hWnd,
- and HIWORD(lParam)=your hWnd.
-
- ============================
-
- THE CSTEST.CPP PROGRAM
- ------------------------
-
- CSTEST.CPP is a program that tests the ClipStac API. To use it, first make
- sure something is in the Clipboard (text or bitmap).
-
- If you run CSTEST.EXE without first loading ClipStac, CSTEST will wait a
- few seconds and then warn you that "ClipStac was not found." It does this
- by attempting to register itself with ClipStac, and when that fails, exiting.
-
- If you run CSTEST after loading ClipStac, it will:
-
- -Register the ClipStac API messages defined in CSAPI.H.
- -Register itself with ClipStac.
- -Push the Clipboard contents onto the ClipStac stack.
- -Pop the item in ClipStac[0] into the Clipboard.
- -Retrieve the identifying info on ClipStac[0].
- -Find the ClipStac item that corresponds to that info.
- -DeRegister itself with ClipStac and exit.
