請教各位大大，我要如何指定MessageDlg的Button Focus？
例如：當觸發MessageDlg時它的Button Focus能指定到[NO]而不是預設的[Yes]

[code delphi]
if MessageDlg('資料尚未儲存，確定要放棄離開？', mtConfirmation, [mbYes, mbNo], 0) = mrNo Then
Abort;
[/code]

用Win32 API   

MessageBox即可使用預設的按鈕

int MessageBox(
HWND hWnd, // handle of owner window
LPCTSTR lpText, // address of text in message box
LPCTSTR lpCaption, // address of title of message box
UINT uType // style of message box
);


Sample:
if IDYES= MessageBox(handle,'Text','Caption',MB_ICONQUESTION MB_YESNO MB_DEFBUTTON2) then
//Yes button was selected.

謝謝大大
