如何得到Windows各种文件类型默认的图标呢？高分求解！

[vbfans]

我在treeview控件里列出了整个C盘下的文件目录，但是，怎么才能让文件图标显示为Windows各种文件类型默认的图标呢？

SHGetFileInfo函数的例子代码：

Option Explicit
Const SHGFI_ICON = &H100
Const SHGFI_DISPLAYNAME = &H200
Const SHGFI_TYPENAME = &H400
Const MAX_PATH = 260
Private Type SHFILEINFO
hIcon As Long ' out: icon
iIcon As Long ' out: icon index
dwAttributes As Long ' out: SFGAO_ flags
szDisplayName As String * MAX_PATH ' out: display name (or path)
szTypeName As String * 80 ' out: type name
End Type
Private Declare Function SHGetFileInfo Lib "shell32.dll" Alias "SHGetFileInfoA" (ByVal pszPath As String, ByVal dwFileAttributes As Long, psfi As SHFILEINFO, ByVal cbFileInfo As Long, ByVal uFlags As Long) As Long
Private Sub Form_Paint()
'KPD-Team 1999
'URL: http://www.allapi.net/
'E-Mail: [e-mail]
Dim FI As SHFILEINFO
'Get file info
SHGetFileInfo "c:\autoexec.bat", 0, FI, Len(FI), SHGFI_DISPLAYNAME Or SHGFI_TYPENAME Or SHGFI_ICON
Me.Cls
Me.Print "Filename: Autoexec.bat"
Me.Print "Typename: " + StripTerminator(FI.szTypeName)
Me.Print "Displayname: " + StripTerminator(FI.szDisplayName)
Me.Print "hIcon: "; FI.hIcon
Me.Print "iIcon: "; FI.iIcon
End Sub
'This fucntion is used to strip al the unnecessary chr$(0)'s
Function StripTerminator(sInput As String) As String
Dim ZeroPos As Integer
'Search the position of the first chr$(0)
ZeroPos = InStr(1, sInput, vbNullChar)
If ZeroPos > 0 Then
StripTerminator = Left$(sInput, ZeroPos - 1)
Else
StripTerminator = sInput
End If
End Function

来晚了，没搞头了！

用SHGetFileInfo函数，详细代码一会儿给你。

我测试过上面这段代码了，确实可以得到图标的ID号，但是我怎么才能把这个DLL中的图标跟TREEVIEW连接起来呢，一般来说treeview好象只接受imagelist中的图标吧？那么，把dll中的图标动态装入imagelist的语句应该怎么写？或者其他方式？

// 取得系统图标列表(以下操作在程序中只能做一次)
CImageList gSysImageList;

SHFILEINFO shFinfo;
HIMAGELIST hImgList = (HIMAGELIST)SHGetFileInfo( "C:\\", 0, &shFinfo,
sizeof( shFinfo ), SHGFI_SYSICONINDEX | SHGFI_SMALLICON );
gSysImageList.Attach(hImgList);



// 使用
// 设置ListView的图标列表为系统图标列表gSysImageList
m_listCtrl->SetImageList(&gSysImageList, LVSIL_SMALL);

// 取得文件strFileName的系统图标序号
SHGetFileInfo( strFileName, 0, &shFinfo, sizeof( shFinfo ),
SHGFI_ICON | SHGFI_SMALLICON | SHGFI_TYPENAME );
// 设置ListView中的图标
nIndex = m_listCtrl->InsertItem(m_listCtrl->GetItemCount(),
strFileName, shFinfo.iIcon);


// 结束使用
gSysImageList.Detach();
