Hi, Is there a reason to be using a vbs file ? In windows a running executable cannot replace itself, but it can rename itself. The way I've done it in the past is: * The running executable renames itself. * It then creates the new executable with the correct name. * Just before returning from main, it starts the new executable (there is a short window of time where both the old and new one can be running, but it doesn't matter if the old one is not using any resources any more ; if need be, the new one can be given a flag to wait for the old one to exit). I find it simpler, and much less likely to trigger an antivirus than a vbs file :) -- Julien Cugnière _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
