dummzeuch 1505 Posted March 15, 2021 I just released dzBdsLauncher 1.0.6. The only change is support for detecting .dproj files created by Delphi 10.4.2 (these have a ProjectVersion of 19.2). If you don't know this tool yet, here is the description: Quote dzBdsLauncher tries to solve the problem of accidentally opening a Delphi project with the wrong Delphi version. While .dproj files can be opened with newer Delphi versions than the one that created them, it does not work the other way round. So if you open a Delphi 10 .dproj file with e.g. Delphi 2007 all you will get is an error message. If you open a Delphi 2007 .dproj file with Delphi 10 it will automatically convert it to the new format used by that version and it will become unreadable by Delphi 2007. dzBdsLauncher tries to solve this using the following methods: File name suffixes project.2007.dproj starts Delphi 2007 … project.2010.dproj starts Delphi 2010 project.xe.dproj starts Delphi XE project.xe2.dproj starts Delphi XE2 … project.xe8.dproj starts Delphi XE8 project.10.dproj starts Delphi 10 project.10-1.dproj starts Delphi 10.1 … project.10-3.dproj starts Delphi 10.3 This is the most reliable method. Reading the <ProductVersion> from the .dproj file Unfortunately these ProductVersions are not unique, so this won’t always work. Reading the <DllSuffix> entry from the .dproj file This entry only exists for DLLs and packages though. Reading the <Disabled_Package> entries from the .dproj and .bdsproj file. dzBdsLauncher can also handle .bdsproj (Delphi 2005 and 2006) and .dof files (Delphi 6 and 7, older versions won’t work). For .dpr files it looks for a corresponding .dproj, .bdsproj or .dof file (in that order) and analyzes it to find the correct Delphi version. And last but not least, dzBdsLauncher can handle .groupproj files. It does this by analyzing the first project found in the group. The idea is to register dzBdsLauncher as the handler for .dpr, .dproj, .bdsproj, .dof and .groupproj files in Windows so your chance for opening the right Delphi version when double clicking such a file will much higher than normal. The tool is released under the MPL on OSDN. You can download the latest version there and the source code is also available. Share this post Link to post
