VB获取执行程序图标
一个CommonDialog，一个CommandButton，一个PictureBOX
Option Explicit
Private Declare Function DrawIcon Lib "user32" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long, ByVal hIcon As Long) As Long
Private Declare Function ExtractIcon Lib "shell32.dll" Alias "ExtractIconA" (ByVal hInst As Long, ByVal lpszExeFileName As String, ByVal nIconIndex As Long) As Long
Private Sub Command1_Click()
Dim total As Long
Dim p(50) As Long
Dim i As Integer
Me.Picture1.Cls
Me.CommonDialog1.Filter = "图标|*.Exe;*.Ico;*.Dll"
Me.CommonDialog1.ShowOpen
If Dir(Me.CommonDialog1.FileName) <> "" Then
If ExtractIcon(App.hInstance, Me.CommonDialog1.FileName, -1) = 0 Then '如果没有图标
MsgBox "No Icon!"
Else
total = ExtractIcon(App.hInstance, Me.CommonDialog1.FileName, -1)
'取得总图标数
For i = 0 To total - 1
p(i) = ExtractIcon(App.hInstance, Me.CommonDialog1.FileName, i) '读取每个图标
Next i
For i = 0 To total - 1 '依次显示每个图标
DrawIcon Picture1.hdc, 34 * i, 0, p(i)
Next i
End If
End If
End Sub
