[wix-users] ShowVersion Attribute

[Stephen Downard]

When using ShowVersion attribute to display WixBundleVersion within the WixExtendedBootstrapperApplication dialog, how can the value be updated if a new Bundle is detected?
Calling the following within OnDetectComplete() does not work.
hr = m_pEngine->SetVariableString(L"WixBundleVersion", m_UpdateBundleVersionInfo.GetString());
