File: find.c
|
|
|
|
Purpose:
|
|
|
|
Manages CDTEST's find/replace dialog box.
|
|
|
|
Functions:
|
|
|
|
- lpfnFilterProc() -- A callback function for a filter that must be
|
|
installed if a modeless dialog is created with
|
|
another dialog as its parent.
|
|
|
|
- DoFindDialog() -- Creates CDTEST's Open/Save dialog.
|
|
|
|
- FindProc() -- Callback function for CDTEST's Find/Replace dlg.
|
|
|
|
- InitFindStruct() -- Fills a FINDREPLACE structure with some defaults.
|
|
|
|
- FillFindDlg() -- Fills CDTESTs Find/Replace dialog with the contents
|
|
of a FINDREPLACE structure.
|
|
|
|
- GetFindDlg() -- Retrieves the users edit's from CDTEST's find/
|
|
replace dialog and puts them in a FINDREPLACE
|
|
structure.
|
|
|
|
- FindReplaceHookProc() -- Callback function for FindText() or ReplaceText()
|
|
which will be called if either of these dialogs
|
|
is created with the FR_ENABLEHOOK flag.
|
|
|
|
- GetFindDlgHandle() -- Returns a handle to a preloaded FindText() template.
|
|
|
|
- GetReplaceDlgHandle() -- Returns a handle to a preloaded ReplaceText() template.
|
|
|
|
- DoFindRepStuff() -- Calls FindText() or ReplaceText().
|
|
|
|
|
|
NOTE: CDTEST does not multithread the FindText() or the ReplaceText()
|
|
common dialogs. The reason for this is that since these dialogs
|
|
are modeless, their creation functions return immediately after the
|
|
dialogs are created as opposed to other dialog functions that
|
|
don't return until after the dialog has been destroyed by the user.
|
|
|
|
As a result, any threads that create modeless dialogs will end
|
|
immediately unless the threads themselves have separate message
|
|
loops. For the sake of clarity, this functionality has not been
|
|
added to CDTEST.
