Xojo Development Needed for Desktop Application Update

Posted 3 weeks ago

Summary

Looking for help with updating an application we have written in Xojo. The last compile was in 2018 Here are details requirements to work with the source code. Third-party plugin dependency: the build includes a MonkeyBread Software (MBS) System Information plugin (MBSSystemInformationPlugin17662.dll). You'd need a current copy of that plugin to recompile — MBS states its plugins support Xojo versions from 2006r4 to today, so it's obtainable, but you may need to (re)acquire a plugin license. Legacy Mac framework calls: I found Carbon-era API calls (e.g., HIWindowChangeAttributes) inside the custom "Taylor Design Framework" code. Modern Xojo builds macOS apps as Cocoa-only, so these calls are likely deprecated/removed — the Windows build should compile far more easily than a fresh macOS build without some code cleanup. Embedded browser control: there's a Browser Plugin.dll in the Windows build folder, which was almost certainly an older embedded-IE-based HTMLViewer implementation. Xojo's HTMLViewer has changed significantly since 2018, so this piece may need updating. The ultimate goal is to bring the code up to current spec to be compatible with newest OSX and Windows versions, and lastly add one or two new reports.
