楼主下次自己查了，呵呵
API的名字叫做
HWND FindText(
LPFINDREPLACE lpfr
);
详细解释见(VS.85).aspx
FindText Function
Creates a system-defined modeless Find dialog box that lets the user specify a string to search for and options to use when searching for text in a document.
Syntax
HWND FindText( LPFINDREPLACE lpfr
);Parameters
lpfr
[in] Pointer to a FINDREPLACE structure that contains information used to initialize the dialog box. The dialog box uses this structure to send information about the user's input to your application. For more information, see the following Remarks section.
Return Value
If the function succeeds, the return value is the window handle to the dialog box. You can use the window handle to communicate with or to close the dialog box.
If the function fails, the return value is NULL. To get extended error information, call the CommDlgExtendedError function. CommDlgExtendedError may return one of the following error codes:
CDERR_FINDRESFAILURE
CDERR_MEMLOCKFAILURE
CDERR_INITIALIZATION
CDERR_NOHINSTANCE
CDERR_LOCKRESFAILURE
CDERR_NOHOOK
CDERR_LOADRESFAILURE
CDERR_NOTEMPLATE
CDERR_LOADSTRFAILURE
CDERR_STRUCTSIZE
CDERR_MEMALLOCFAILURE
FRERR_BUFFERLENGTHZERO
Remarks
The FindText function does not perform a search operation. Instead, the dialog box sends FINDMSGSTRING registered messages to the window procere of the owner window of the dialog box. When you create the dialog box, the hwndOwner member of the FINDREPLACE structure is a handle to the owner window.
Before calling FindText, you must call the RegisterWindowMessage function to get the identifier for the FINDMSGSTRING message. The dialog box procere uses this identifier to send messages when the user clicks the Find Next button, or when the dialog box is closing. The lParam parameter of the FINDMSGSTRING message contains a pointer to a FINDREPLACE structure. The Flags member of this structure indicates the event that caused the message. Other members of the structure indicate the user's input.
If you create a Find dialog box, you must also use the IsDialogMessage function in the main message loop of your application to ensure that the dialog box correctly processes keyboard input, such as the TAB and ESC keys. IsDialogMessage returns a value that indicates whether the Find dialog box processed the message.
You can provide an FRHookProc hook procere for a Find dialog box. The hook procere can process messages sent to the dialog box. To enable a hook procere, set the FR_ENABLEHOOK flag in the Flags member of the FINDREPLACE structure and specify the address of the hook procere in the lpfnHook member.
Windows 95/98/Me: FindTextW is supported by the Microsoft Layer for Unicode (MSLU). To use this, you must add certain files to your application, as outlined in Microsoft Layer for Unicode on Windows 95/98/Me Systems.
