新建From1(窗体),新建Command1(按钮CommandButton),代码:
Private Const MAX_FILENAME_LEN = 256
Private Declare Function FindExecutableA Lib "shell32.dll" (ByVal lpFile As String, ByVal lpDirectory As String, ByVal lpResult As String) As Long
Private Function FindExecutable(s As String) As String
Dim i As Integer
Dim s2 As String
s2 = String(MAX_FILENAME_LEN, 32) & Chr$(0)
i = FindExecutableA(s & Chr$(0), vbNullString, s2)
If i > 32 Then
FindExecutable = Left$(s2, InStr(s2, Chr$(0)) - 1)
Else
FindExecutable = ""
End If
End Function
Private Sub Command1_Click()
MsgBox FindExecutable(App.Path & "/123.txt")
End Sub
运行结果:
C:\Windows\system32\NOTEPAD.EXE
