问题
On a Windows Mobile 6 or CE 5 device, I need to install a CAB file and then initiate a reboot.
I am aware of custom actions. You need to create a setup.dll for the CAB file in native C++.
So I have the following code already made
codeINSTALL_EXIT Install_Exit(HWND hwndParent,
LPCTSTR pszInstallDir,
WORD cFailedDirs,
WORD cFailedFiles,
WORD cFailedRegKeys,
WORD cFailedRegVals,
WORD cFailedShortcuts)
{
MessageBox(hwndParent,
_T("A reboot is required to complete installation, Press OK to reboot."),
_T("Reboot required"),
MB_OK);
SetSystemPowerState(NULL, POWER_STATE_RESET, 0);
return codeINSTALL_EXIT_DONE;
}
SetSystemPowerState will do a warm boot on the device. The problem is that since the installation does not finish (return code INSTALL_EXIT_DONE
is not reached), it complains that is it unable to install the application when you attempt to remove it at a later time. Removal of the reboot is an instant cure to this problem.
I have seen on other .CAB installs a polite message appear saying "A restart is required to complete installation..."
with no OK/Cancel button. Then the device reboots after two seconds of displaying the message. Furthermore this software can be uninstalled without a problem.
I am looking to achieve the same functionality seen in other CAB files like the above, a timeout system popup, followed by a reboot and the ability to uninstall the application from the remove programs option on the device.
Another possible solution I found yesterday was to return CONFIG_S_REBOOTREQUIRED instead. However, this is not defined and as such will not compile. The defined returns for codeINSTALL_EXIT are as below.
Using typedef enum
{
codeINSTALL_EXIT_DONE = 0, // @comm Exit the installation successfully
codeINSTALL_EXIT_UNINSTALL // @comm Uninstall the application before exiting the installation
}
codeINSTALL_EXIT;
回答1:
From this thread I understand that one needs to inform the installing process that a reboot is required after installing the CAB package.
So instead of codeINSTALL_EXIT_DONE
just return CONFIG_S_REBOOTREQUIRED
(without SetSystemPowerState).
I usually restart windows with ExitWindowsEx instead of SetSystemPowerState
.ExitWindowsEx(EWX_REBOOT | EWX_DEFER, 0);
should restart asynchronously, giving time to the setup process to finish.
