Question

SHFILEINFO sfi;
SHGetFileInfo( "硬盘", FILE_ATTRIBUTE_DIRECTORY, &sfi, sizeof(sfi), SHGFI_USEFILEATTRIBUTES|SHGFI_SYSICONINDEX|SHGFI_TYPENAME);
HTREEITEM hItem = m_CtrlTree->InsertItem("硬盘",sfi.iIcon,sfi.iIcon, TVI_ROOT);这样显示的是一个文件夹的形式，如何显示一个硬盘的形式呢？？高手拿分。

Answer 1

SHGetFileInfo("C:\\" , "硬盘", FILE_ATTRIBUTE_DIRECTORY, &sfi, sizeof(sfi) , SHGFI_SMALLICON | SHGFI_SYSICONINDEX);

Answer 2

给你一个例子,用来获得全部目录内容以及图标

if(FAILED(hr))

errorline:

}如果是文件夹,就是文件夹的图标,如果是驱动器,就是驱动器的图标,如果是文件,就是文件图标
