Hi there,
I have a problem when trying to detect whether my Bundle is already
installed. My usecase is as follows:
I am creating a bundle with a custom UI. On startup I need to check
whether my bundle is already installed in the exactly same version to
determine if I have to show the maintenance page (if the versions
match), to block installation(if a newer version is already installed)
or show the install page (else). So I make a call to
_bootstrapperApplication.Engine.Detect();
My first idea now was to handle the event
_bootstrapperApplication.DetectRelatedBundle and somehow determine
whether the productcodes are different. This is not possible as I can't
get the product code of the bundle that is going to be installed.
Then I thought it might be an idea, to check for some package which is
unique for my product. So I added the line
_bootstrapperApplication.DetectPackageComplete = DetectedPackage; (see
below) but it doesn't work as I expected:
private void DetectedPackage(object sender,
DetectPackageCompleteEventArgs e)
{
PackageState.Obsolete
if (e.PackageId.Equals("mypackage",
StringComparison.Ordinal))
{
_state = (e.State == PackageState.Present) ?
InstallationState.DetectedPresent : InstallationState.DetectedAbsent;
}
}
- If for example version 2.8 is installed and the Package in my
Bundle now has version 2.7 it returns PackageState.Absent (or Obsolete?
I can't reproduce it at the moment) which is just fine
- If version 2.8 is installed and the Package in my Bundle now has
version 2.8, too, it syas e.State = PackageState.Present which is
correct, too.
- But if version 2.8 is installed and the Package in my Bundle now
has version 2.9, I get e.State = PackageState.Present and would show the
maintenance page although I would need to show install page and install
the newer version.
Is this intended or is it a bug? Am I getting something wrong?
What I am doing as a workaround is, on DetectRelatedBundle event I make
some very ugly version comparison. Is there any other option?
Any help appreciated, thanks in advance!
Regards,
Sabine
