问题 I am porting an excel addin (used shimloader) to exceldna, and yeah, I have seen the other SO (and off SO) questions but nothing resolves my question, and I'm hoping there are newer solutions. The code is simple. [ExcelFunction(Name="DoSomething")] string DoSomething() { var xl = ExcelDna.Application; var callerCell = xl.Caller; var row = getRow(excelReference.RowFirst+1, callerCell.WorkSheet) ; } In GetRow(): var row = (Range)worksheet.Rows[row]; var cell = (Range)bracketRow.Columns[4]; When

How to check Excel cell format in C# to see if cell value is a date

问题 Good Morning All! I have been developing a project for some time in which users can publish a set of values for a set of dates. e.g. The user would select a Range in Excel which would contain date values, and an equally sized Range which contains values to publish corresponding to these dates. What I need to do (C#) is check the cell formatting of both Ranges to see which one is 'actually' a date, I've been using ExcelDNA and since all dates are returned as doubles, I can technically parse my

问题 I'm working on an add-in that periodically requests a recalculation using the following: ((Excel.Application) xlApp).Calculate() If the user happens to be editing a formula at the time, Excel breaks the users formula when I do this. I expect the action to fail due to user activity, which it does, but not before oddly interrupting whatever formula the user is typing. For example, if the user is in the middle of typing into a cell =SUM(1+2+ , as soon as I run the above line of code, their input

Excel ExcelDNA C# / Try to copy Bloomberg BDH() behavior (writing Array after a web request)

由 风格不统一 提交于 2019-12-03 10:48:24
问题 I want to copy Bloomberg BDH behavior. BDH makes a web request and write an array (but doesn't return an array style). During this web request, the function returns "#N/A Requesting". When the web request finished, the BDH() function writes the array result in the worksheet. For example, in ExcelDNA, I succeed to write in the worksheet with a thread. The result if you use the code below in a DNA file, the result of =WriteArray(2;2) will be Line 1 > #N/A Requesting Data (0,1) Line 2 > (1,0) (1
