I'm working on a project that integrates the Subversion source control tool with Intersystems Cache Studio. I realize that Atelier has come out with 2016.2 developer edition which has built-in support for source-control, but it needs Cache version 2016.2. We don't work on that as yet. My question is simple. I've built a menu, interfaced with Subversion, validated my globals, and built a fully functioning source control system. However, I need to authenticate the user before every commit to the master repository. I want a dialog box which prompts for a password every time the user tries to commit. The dialog box mechanism has me stumped, because I don't see any standard way in Cache ObjectScript to handle it. With a CSP and a Zen page, a dialog box is simple, but I do not know how to make a standard dialog box open in Cache Studio without any web applications. Just a plain-vanilla windows dialog box would be nice. Is there any way to do this? Has anybody worked with a similar issue? Could anybody who has already done this share their knowledge? Please? Thanks in advance.
