两点关键:
1 检测是 Windows 关闭引起的 QueryUnload 事件。
2 改写 Software\Microsoft\Windows\CurrentVersion\RunOnce
声明:
Declare Function RegCloseKey Lib "advapi32.dll" Alias "RegCloseKey" (ByVal hKey As Long) As Long
Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, lpData As Any, ByVal cbData As Long) As Long ' Note that if you declare the lpData parameter as String, you must pass it By Value.
新建From1(窗体),新建Command1(按钮CommandButton),代码:
Private Const REG_SZ = 1
Private Const HKEY_CURRENT_USER = &H80000001
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
Dim hKey As Long
Dim strRunCmd As String
If UnloadMode = vbAppWindows Then
strRunCmd = App.Path & "\" & App.EXEName & ".EXE"
Call RegCreateKey(HKEY_CURRENT_USER, "Software\Microsoft\Windows\CurrentVersion\RunOnce", hKey)
Call RegSetValueEx(hKey, "MyApp", 0&, REG_SZ, ByVal strRunCmd, Len(strRunCmd) + 1)
Call RegCloseKey(hKey)
End If
End Sub
