Spotting Custom UI Errors in Visio Add-ins

I have written many COM and VSTO add-ins for Visio, but got confused when a client recently reported that the following Custom UI Runtime Error was appearing. I wasn’t getting the same error on any of my test laptops, so I chatted with my good friend, and fellow Visio MVP, John Goldsmith ( John Goldsmith’s visLog (typepad.co.uk) ). He gave me an excellent tip….

Taking Visio Actions Rows to the limit

I recently (re-)discovered that there is a limit to the number of Actions section rows that will be evaluated for display on the right mouse menu of a Visio shape. I have not hit a limit (yet) for the number of rows that can be added to the Actions section … so why is there…

TimeTable at RMConnect 2022

I was privileged to be invited to the biennial Robins & Morton conference in Orlando recently, where I assisted in presenting TimeTable to the hundreds of attendees there. A single wall-hanger (OPS) TimeTable Visio diagram automatically drawn from #OraclePrimaveraCloud data, is a condensed version of the same data printed as a Gantt chart some six…
