另外,刚才查了一下API函数库,利用SystemParametersInfo API 也可进行读取或设置.

Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long

Private Const SPI_SETSCREENREADER = 71

Private Const SPI_SETSCREENSAVEACTIVE = 17

Private Const SPI_SETSCREENSAVETIMEOUT = 15

Private Const SPI_GETSCREENREADER = 70

Private Const SPI_GETSCREENSAVEACTIVE = 16

Private Const SPI_GETSCREENSAVETIMEOUT = 14

Private Const SPIF_UPDATEINIFILE = &H1

Private Const SPIF_SENDWININICHANGE = &H2

补充：你的程序必须能处理启动参数，因为屏保程序运行与设置时的启动参数是不同的。

设备所限，无法知道你的问题所在。

SystemParametersInfo的用法如下

Private Const SPI_SETSCREENSAVETIMEOUT = 15
Private Const SPIF_SENDWININICHANGE = &H2
Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long

Private Sub Command1_Click()'立即启动屏幕保护
SystemParametersInfo SPI_SETSCREENSAVETIMEOUT, 1, 0&, SPIF_SENDWININICHANGE
End

狼行天下你好：按照你的指导，先引用Registry Access Functions library(RegObj.dll)]，可是引用后发现没能找到你在代码中使用的方法只有下面的几个，不知为何，望指教！
myreg.AddRootRegKey
myreg.RegKeyFromHKey
myreg.RegKeyFromString
myreg.RemoteRegistry

------------------------
可能与版本有关。我的WINDOWSXP+VBSP6(regobj.dll),windowsme+VBSP5（regtool5.dll)都能执行。
你也可以用别的注册表读写办法操作以上几个KEY，SUBKEY。

另外，关于利用SystemParametersInfo API 进行读取或设置.如何做，能否说得明白一点，最好有一个实例
谢谢

访问注册表,现写一个:

'先引用Registry Access Functions library(RegObj.dll)]:

Private Sub Command1_Click() ' get screensaver
Dim myReg As New Registry, ScreenSaveActive As String, savername As String, ScreenSaveTimeOut As String, ScreenSaverIsSecure As String, msg As String
myReg.GetKeyValue HKEY_CURRENT_USER, "Control Panel\Desktop", "ScreenSaveActive", ScreenSaveActive
myReg.GetKeyValue HKEY_CURRENT_USER, "Control Panel\Desktop", "ScreenSaverIsSecure", ScreenSaverIsSecure
myReg.GetKeyValue HKEY_CURRENT_USER, "Control Panel\Desktop", "ScreenSaveTimeOut", ScreenSaveTimeOut
myReg.GetKeyValue HKEY_CURRENT_USER, "Control Panel\Desktop", "SCRNSAVE.EXE", savername

msg = "savername" & vbTab & savername
msg = msg & vbCrLf & "ScreenSaveActive" & vbTab & CBool(ScreenSaveActive)
msg = msg & vbCrLf & "ScreenSaverIsSecure" & vbTab & CBool(ScreenSaverIsSecure)
msg = msg & vbCrLf & "ScreenSaveTimeOut " & vbTab & ScreenSaveTimeOut & " s"
MsgBox msg
End Sub

Private Sub Command2_Click() 'set screensaver
Dim myReg As New Registry
myReg.UpdateKey HKEY_CURRENT_USER, "Control Panel\Desktop", "ScreenSaveActive", "1"
myReg.UpdateKey HKEY_CURRENT_USER, "Control Panel\Desktop", "ScreenSaverIsSecure", "0"
myReg.UpdateKey HKEY_CURRENT_USER, "Control Panel\Desktop", "ScreenSaveTimeOut", "120"
myReg.UpdateKey HKEY_CURRENT_USER, "Control Panel\Desktop", "SCRNSAVE.EXE", "c:\WINDOWS\system32\ssbezier.scr"
MsgBox "set screensaver is ok"
End Sub
