带有自己的按钮文本的消息框

Question

A lot of applications on Windows show plain message boxes just with "Yes"/"No" or "OK"/"Cancel" buttons. Often it gets worse on non-English Windows' that the text is in English, but the buttons are labeled in the Windows' language.

Is there no simple API to show a message box with own button labels, eg "Delete" or "Keep"?

Answer 1

There is indeed such a Win32 function. It is TaskDialogIndirect . Note that it was introduced in Vista and so if you are still attempting to support XP, then you would need to provide a fall back option for that platform.

Answer 2

Like DavidHeffernan said, you should use TaskDialogIndirect() , as it natively supports custom buttons. It is only available on Vista and later, though.

On XP and earlier, you can customize the button captions on a standard MessageBox() (or really, any customization you want) by using SetWindowsHookEx() to install a thread-local WH_CBT hook, or use SetWinEventHook() , to obtain the dialog's HWND when it is created, then you can manipulate the dialog however you want. You can use GetDlgItem() to get the HWND of the individual buttons (and can thus use standard API functions/messages with them), and/or use GetDlgItemText() to change their captions. The CtrlID of each button is the same value that MessageBox() returns when that button is clicked.

Answer 3

This Projct on Codeproject provides a pretty good drop in replacement for MessageBox , that allows to replace buttons labels among other features.

It is basically a rewritten MessageBox function that is a superset of the standard Windows MessageBox function. Full source code is provided so you can adapt is easily to your needs if needed.

And it's pure Win32, no MFC is involved here.
