'新建一个窗体,在窗体上添加一个TextBox用来输入文件路径
'和两个picturebox用来显示提取到的图标
'以下是窗体中的代码
Private Sub Text1_Change() '要显示的图标路径
Dim hImgSmall As Long
Dim fName As String '驱动器号、文件夹名、文件名

Dim hImgLarge As Long

有了上面的代码,你在Text1中输入一个文件路径就可以看到图标了,但我还要给你说的是,你直接输快捷方式的路径是不对的,你要先获得快捷方式所指向的文件路径,然后显示这个文件路径的图标才是正确的,挺简单的。
还有什么不懂的,你可以来找我!
晕~
获得快捷方式的信息更简单,看下面:
Option Explicit
'注意要引用:Microsoft Shell Controls And Automation
Private Sub Command1_Click()
Dim FolderPath As String
Dim ShortcutName As String
Dim WorkDir As String
Dim Arguments As String, Description As String
Dim IconIdx As Long, ShowCommand As Long
FolderPath = "C:\Documents and Settings\Administrator\桌面" '快捷方式所在的目录
ShortcutName = "ToolBox.exe.lnk" '快捷方式的文件名,注意要加lnk
Dim IconFile As String
Call GetShellLinkInfo(FolderPath, ShortcutName, WorkDir, Arguments, Description, IconFile, IconIdx, ShowCommand)
End Sub
Private Sub GetShellLinkInfo(ByVal FolderPath As String, ByVal ShortcutName As String, WorkDir As String, _
Arguments As String, Description As String, IconFile As String, IconIdx As Long, _
ShowCommand As Long)
Dim mShell As Shell, mFile As FolderItem, mFolder As Folder
Dim lnk As ShellLinkObject, i As Long
Set mShell = New Shell
Set mFolder = mShell.NameSpace(FolderPath)
On Error Resume Next
Set mFile = mFolder.Items.Item(ShortcutName)
If Err Then
MsgBox ShortcutName & " is inaccessable!"
Err.Clear
GoTo exit_sub
Else
If mFile.IsLink Then
Set lnk = mFile.GetLink
WorkDir = lnk.WorkingDirectory
Arguments = lnk.Arguments
Description = lnk.Description
IconIdx = lnk.GetIconLocation(IconFile)
ShowCommand = lnk.ShowCommand
MsgBox "Name: " & mFile.Name & vbCrLf & _
"Description: " & lnk.Description & vbCrLf & _
"Path: " & lnk.Path & vbCrLf & _
"WorkingDirectory: " & lnk.WorkingDirectory & vbCrLf, vbInformation
Else
MsgBox ShortcutName & " is not a shortcut!", vbInformation
End If
End If
exit_sub:
Set lnk = Nothing
Set mFile = Nothing
Set mFolder = Nothing
Set mShell = Nothing
End Sub
