Re: [Lazarus] ARM-WinCE - db engine, printing
Sorry for the late reaction, but I wanted to get to know MiniLib a bit first. It is very promising, thank you very much for the links and for making your work available! :) As development Status of the project is set to stable I am likely to try to use MiniLib with my WinCe project. A few questions beforehand: - Will you be available if support/help is required? (I would not want to force you into it at all, so NO is a good answer too..) - Is there any example program or documentation to help learning how to use MiniLib features?
