I want to upgrade a program written in Visual Basic 5 on a number of clients machines. I had no difficulty creating the distribution disk from instructions in the programmers manual, but I can't see any reference to creating an upgrade disk. I can write a dos batch file to copy the upgraded files but I need to open two excel sheets, which are part of the application, save them and close them to complete the upgrade. While this is easy to do manually I want to automate it and preferably from a visual basic program without having to use the dos batch file. Hope someone out there can help.
