如何得到Windows各种文件类型默认的图标

Answer 1

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:
'E-Mail: KPDTeam@Allapi.net
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
