如何在CListCtrl显示文件中的文件，并根据文件本身的类型来显示图标（在系统中显示）

[zhaolaoxin]

CListCtrl的图标是由程序控制的

比如：
// ADDFILE按钮的事件
void CFilePage::OnBtnadd()
{
// TODO: Add your control notification handler code here
char szFilters[] = "All Files (*.*)|*.*||";

CFileDialog dlg(FALSE, "*", "*.*" , OFN_NOVALIDATE| OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT, szFilters, this);

dlg.m_ofn.lpstrTitle = "Select Files";

if (dlg.DoModal() == IDOK)
{
POSITION pos = dlg.GetStartPosition();
while (pos != NULL)
{
CString strPath = dlg.GetNextPathName(pos);
if (strPath.Find(":\\\\") == 1 && strPath.GetLength() > 4)
{
// this means we have an invalid path that looks like this:
// C:\\foo.bmp
// We need to cut out the extra slash
CString temp;
temp = strPath.Left(3);
temp += strPath.Mid(4);
strPath = temp;
}
AddFiles(strPath, TRUE);
}
}
}

// AddFiles
void CFilePage::AddFiles(LPCTSTR lpszFileName, BOOL bAddToDocument)
{
int nIcon = GetIconIndex(lpszFileName, FALSE, FALSE);
CString strSize;
CFileFind filefind;

// get file size
if (filefind.FindFile(lpszFileName))
{
filefind.FindNextFile();
strSize = FormatSize(filefind.GetLength());
}
else
strSize = FormatSize(0);

// split path and filename
CString strFileName = lpszFileName;
CString strPath;

int nPos = strFileName.ReverseFind('\\');
if (nPos != -1)
{
strPath = strFileName.Left(nPos);
strFileName = strFileName.Mid(nPos + 1);
}

// insert to list
int nItem = m_FileList.GetItemCount();
m_FileList.InsertItem(nItem, strFileName, nIcon);
m_FileList.SetItemText(nItem, 1, strSize);
m_FileList.SetItemText(nItem, 2, GetTypeName(lpszFileName));
m_FileList.SetItemText(nItem, 3, strPath);
}
// 获得文件图标
int GetIconIndex(LPCTSTR lpszPath, BOOL bIsDir, BOOL bSelected)
{
SHFILEINFO sfi;
memset(&sfi, 0, sizeof(sfi));

if (bIsDir)
{
SHGetFileInfo(lpszPath,
FILE_ATTRIBUTE_DIRECTORY,
&sfi,
sizeof(sfi),
SHGFI_SMALLICON | SHGFI_SYSICONINDEX | SHGFI_USEFILEATTRIBUTES | (bSelected ? SHGFI_OPENICON : 0)
);

return sfi.iIcon;
}
else
{
SHGetFileInfo (lpszPath,
FILE_ATTRIBUTE_NORMAL,
&sfi,
sizeof(sfi),
SHGFI_SMALLICON | SHGFI_SYSICONINDEX | SHGFI_USEFILEATTRIBUTES | (bSelected ? SHGFI_OPENICON : 0)
);
return sfi.iIcon;
}
return -1;
}

对了，在对话框初始化的时候还要将系统的ICO列表读取出来
HIMAGELIST himlSmall;
HIMAGELIST himlLarge;
SHFILEINFO sfi;

himlSmall = (HIMAGELIST) SHGetFileInfo ((LPCSTR) "C:\\",
0, &sfi, sizeof (SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_SMALLICON);

himlLarge = (HIMAGELIST) SHGetFileInfo ((LPCSTR) "C:\\",
0, &sfi, sizeof (SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_LARGEICON);

if (himlSmall && himlLarge)
{
::SendMessage(m_FileList.m_hWnd, LVM_SETIMAGELIST, (WPARAM)LVSIL_SMALL, (LPARAM)himlSmall);
::SendMessage(m_FileList.m_hWnd, LVM_SETIMAGELIST, (WPARAM)LVSIL_NORMAL, (LPARAM)himlLarge);
return TRUE;
}

此段程序是我从我们的项目中摘抄下来的，这段我还没有仔细分析过，是一个同事写的，还有点缺憾，他把系统盘指定在C:了，我把初始化那部分代码改成这样了。
HIMAGELIST himlSmall;
HIMAGELIST himlLarge;
SHFILEINFO sfi;
char cSysDir[MAX_PATH];
CString strBuf;

memset(cSysDir, 0, MAX_PATH);

GetWindowsDirectory(cSysDir, MAX_PATH);
strBuf = cSysDir;
sprintf(cSysDir, "%s", strBuf.Left(strBuf.Find("\\")+1));
// 以上是活得获得系统盘符
himlSmall = (HIMAGELIST) SHGetFileInfo ((LPCSTR) cSysDir,
0, &sfi, sizeof (SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_SMALLICON);

himlLarge = (HIMAGELIST) SHGetFileInfo ((LPCSTR) cSysDir,
0, &sfi, sizeof (SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_LARGEICON);

if (himlSmall && himlLarge)
{
::SendMessage(m_FileList.m_hWnd, LVM_SETIMAGELIST, (WPARAM)LVSIL_SMALL, (LPARAM)himlSmall);
::SendMessage(m_FileList.m_hWnd, LVM_SETIMAGELIST, (WPARAM)LVSIL_NORMAL, (LPARAM)himlLarge);
return TRUE;
}
return FALSE;

我那个同事是个荷兰人，看来我们不能完全轻信鬼老啊
