/************************************************************************ 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. ************************************************************************/ //#include "global.h" //#include //#include "resource.h" #include "headtest.h" #include "headdlg.h" /* All functions used in this module + some exported ones */ void InitGetItemCountStruct(HWND, LPGETITEMCOUNT) ; void FillGetItemCountDlg(HWND, LPGETITEMCOUNT) ; void GetGetItemCountDlg(HWND, LPGETITEMCOUNT) ; extern UINT uMode ; // extern LONG MyAtol(LPSTR, BOOL, BOOL) ; //UINT APIENTRY FindReplaceHookProc(HWND, UINT, UINT, LONG) ; void DoGetCountRepStuff(HWND, LPGETITEMCOUNT) ; /* All global variables used in this module */ HWND hwndFind ; HWND hwndMainDialog ; GETITEMCOUNT gic ; LPGETITEMCOUNT lpGic ; char szFindWhat[100] ; char szReplaceWith[100] ; char szTemplate[40] ; char szTemp[100]; HANDLE hResFind, hDialogFind ; HANDLE GetFindDlgHandle(void) ; HANDLE GetReplaceDlgHandle(void) ; HBRUSH hBrushDlg ; HBRUSH hBrushEdit ; //brush handles for new colors done with hook proc HBRUSH hBrushButton ; /************************************************************************ Function: lpfnFilterProc(int, WPARAM, LAPRAM) Purpose: This is needed if a modeless dialog is created with its parent as another dialog box.
