将integer指向TBSAVEPARAMS？(TBSAVETB_SAVERESTORE怎么用？) (150分)

TB_SAVERESTORE可以将自定义过的工具栏存到注册表中，也可以从注册表恢复。<br>请问TB_SAVERESTORE怎么用？<br><br>相关帖子：http://www.delphibbs.com/delphibbs/dispq.asp?lid=1375713

&nbsp; &nbsp;你的代码没有问题，这个在 delphi 5 中就有。<br>&nbsp; &nbsp; 主要是 delphi 的文档少了关键的一段话，需要Toolbar 的父窗口对“通过”消息<br>TBN_GETBUTTONINFO 进行处理！！！！<br>&nbsp; &nbsp; 其中的处理涉及 按钮 id 文本 图像等各种信息内容，比较适合VC的处理。<br>如果只是想保存工具栏的位置和状态信息还不如用自己的方式进行处理。<br><br>To save and restore a toolbar's settings using the TB_SAVERESTORE message, the parent window of the toolbar control must implement a handler for the TBN_GETBUTTONINFO notification message. The toolbar uses this notification to retrieve information about the buttons as they are read out of the registry. <br><br>以下是VC中的示例：<br><br>SBAR.CPP<br>//**************************************************************************** // &nbsp;Module: &nbsp;
