How can an Excel Add-In respond to events in any worksheet?

问题 Our workbooks are server-generated SpreadsheetML , which cannot include any VBA code. Creating native Excel files or Excel 2007 XML files is also not an option, unfortunately. So, I have an Excel Add-In (VBA, not XLL) that each of our users installs to add some extra UDFs, etc. that our workbooks need. This works great, but now I need to have a macro that needs to execute every time the user changes the text in any cell, regardless what workbook they are actively using at the time. So far, I\

问题 I am getting \"HRESULT: 0x800A03EC\" error when running Excel add-in with following code: Excel.Range rng = ActiveSheet.Cells[x, y] as Excel.Range; string before = rng.Value2; string cleanV = System.Text.RegularExpressions.Regex.Replace(before, @\"\\s+\", \"\"); rng.set_Value(cleanV); When error happens X and Y are set to 1, thus Excel range is not violated. I searched extensively and tried a number of ways of setting the cell value (eg. Cells[x,y], range.set_Value()) but am at loss why this

问题 I\'ve created an Excel Add-In, and one of the functions of this Add-In, lets say New_Years currently takes in 2 years and outputs every New Years day between those 2 years as an array in Excel.

The problem is that I have to know there are going to be 3 dates in that time, select 3 cells, enter my formula in the top cell, and then hit Ctrl + Shift + Enter to fill out the array. I use XLW version

Choosing between MEF and MAF (System.AddIn)

问题 The Managed Extensibility Framework (MEF) and Managed AddIn Framework (MAF, aka System.AddIn) seem to accomplish very similar tasks. According to this Stack Overflow question, Is MEF a replacement for System.Addin?, you can even use both at the same time. When would you choose to use one vs. the other? Under what circumstances would you choose to use both together? 回答1: I've been evaluating these options and here's the conclusion that I came to. MAF is a true addon framework. You can separate
