ShellExecute 默认用关联的程序打开
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
Call ShellExecute(hwnd, "Open", "test.bmp", "", CurrentProject.Path, 1)
