问题
I have a WiX Burn custom installer using ManagedBootstrapperApplicationHost. After installing one of the prerequisite Microsoft Windows Installer 4.5 I forcefully reboot the PC (Windows XP) using:
<ExitCode Behavior="forceReboot"/>
The Bundle chain looks like this:
<Chain>
<PackageGroupRef Id="WindowsInstaller45"/>
<PackageGroupRef Id="Netfx2Full"/>
<PackageGroupRef Id="Netfx4Full"/>
<PackageGroupRef Id="CustomPkg"/>
<PackageGroupRef Id="SQLExpress"/>
</Chain>
After it reboots, I want my installation to continue after that, but it actually detects the installation and shows Uninstall option.
How can I detect an unfinished installation when reboot happens during installation?
回答1:
When the Bundle is started again after a restart the BOOTSTRAPPER_COMMAND struct passed to your BootstrapperApplicationCreate function contains a resumeType field that will be set to BOOTSTRAPPER_RESUME_TYPE_REBOOT. In managed code, the BootstrapperApplication class contains a Command property that contains the resume field.
For example in managed code, to tell that your BootstrapperApplication started after a restart, you can check:
if (BootstrapperApplication.Command.resume == ResumeType.Reboot)
{
// started after restart, go straight to Detect->Plan->Apply to finish the
// previous operation. BootstrapperApplication.Command.action will tell us
// the action to complete.
}
else
{
// started normally, show typical UI scenarios.
}
