BrowseCallbackProc

typedef int ( CALLBACK *BrowseCallbackProc)(
HWND hwnd,
UINT uMsg,
LPARAM lParam,
LPARAM lpData
);

这个函数是当 SHBrowseForFolder 函数弹出Browse For Folder对话框后，应用程序响应该对话框消息的函数。

有四种消息：

BFFM_INITIALIZED	对话框已经完成初始化
BFFM_IUNKNOWN	An IUnknown interface is available to the dialog box.
BFFM_SELCHANGED	The selection has changed in the dialog box.
BFFM_VALIDATEFAILED	The user typed an invalid name into the dialog's edit box. A nonexistent folder is considered an invalid name.
