首先要先检查下你加载视频的文件路径是否正确

[xingyw112]

怎么没人回帖呀

[yaozhiyong110]

首先你的程序里 CString strPath; CString strTitle; strPath = ff.GetFilePath(); strTitle = ff.GetFileTitle(); 这里用个map来保存下 strTitle 和 strPath的对应关系 不然到时你获取到title得不到path也播放不了文件 HTREEITEM item = m_FileTree.GetSelectedItem(); CString text = m_FileTree.GetItemText(item); text就是你节点显示的内容 就是你上面的title 然后从map里找到path 最后就是Media Player去播放这个path的文件

[yaozhiyong110]

HTREEITEM item = m_FileTree.GetSelectedItem(); CString text = m_FileTree.GetItemText(item); 是在OnDblclkFiletree里...

[xingyw112]

具体我应该怎么弄 我之前也弄了 播放提示不能播放此文件

[xingyw112]

我照着你说的弄啦 可是还是不行 麻烦你看看，我加的对不对，看看那哪里不对 这是源码连接 麻烦你啦 谢谢 http://pan.baidu.com/s/1ntmmMiX 4gx3

我调试了下 你的BrowseDir函数else if按下面改下 BrowseFile这个函数你根本没用到... else if(!file.IsDirectory() && !file.IsDots()) { CString strPath = file.GetFilePath(); CString strTitle = file.GetFileTitle(); m_mapPath[strTitle]=strPath; m_FileTree.InsertItem( strTitle, 0, 0, parent ); }

[xingyw112]

谢谢 已经能用了 点数怎么给你呀

[xingyw112]

还有个问题 我调试的时候 树形控件为什么没有显示哪 那怎么调试呀

定义这个成员变量 map<CString,CString> m_mapPath; 然后 strPath = ff.GetFilePath(); strTitle = ff.GetFileTitle();后面 加上 m_mapPath[strTitle]=strPath; 最后OnDblclkFiletree里面 HTREEITEM item = m_FileTree.GetSelectedItem(); CString title= m_FileTree.GetItemText(item); CString path=m_mapPath[title]; 然后就是用mediaplayer播放这个path

[yaozhiyong110]

调试你的BrowseDir函数就行了 树控件显示的内容就是BrowseDir里面m_FileTree.InsertItem这个动作 BrowseDir( "成绩表", NULL ); 这个就是从当前目录里的 “成绩表”这个文件夹开始搜索...
