在安装.CAB WM时重新启动

本文介绍了在安装.CAB WM时重新启动的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在Windows Mobile 6或CE 5设备上，我需要安装CAB文件，然后重新启动。

On a Windows Mobile 6 or CE 5 device, I need to install a CAB file and then initiate a reboot.

我知道自定义操作。您需要在本机C ++中为CAB文件创建一个setup.dll。

I am aware of custom actions. You need to create a setup.dll for the CAB file in native C++.

所以我有以下代码

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将在设备上执行热启动。问题是，由于安装没有完成（返回代码 INSTALL_EXIT_DONE 未达到），它抱怨说，它是无法安装应用程序，当您尝试删除它以后的时间。删除重新启动是即时解决这个问题。

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.

我在其他.CAB安装看到一个礼貌的消息出现重新启动是需要完成安装...，没有确定/取消按钮。然后，设备在显示消息两秒后重新启动。此外，这个软件可以卸载没有问题。

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.

我正在寻找实现相同的功能看到在其他CAB文件像上面，超时系统弹出，其次是重新启动和从设备上的删除程序选项卸载应用程序。

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.

我昨天找到的另一个可能的解决方案是以返回CONFIG_S_REBOOTREQUIRED。但是，这没有定义，因此不会编译。 codeINSTALL_EXIT的定义返回如下。

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;

推荐答案

从这个线程我明白，需要通知安装过程重启是

From this thread I understand that one needs to inform the installing process that a reboot is required after installing the CAB package.

因此，代替 codeINSTALL_EXIT_DONE 只需返回 CONFIG_S_REBOOTREQUIRED （不含SetSystemPowerState）。

So instead of codeINSTALL_EXIT_DONE just return CONFIG_S_REBOOTREQUIRED (without SetSystemPowerState).

我通常使用 ExitWindowsEx ，而不是 SetSystemPowerState 。 ExitWindowsEx（EWX_REBOOT | EWX_DEFER，0）; 应该异步重新启动，让安装过程完成。

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.
