In Workbook - Writecell invalid range exception is not handled.
Due to wrong calculation if range is invalid like - A0 the value is writing for whole column from A1 - A1048576. File size increased from 8 KB to 5626 KB.
For excel application scope “The range does not exist.” - exception captured in catch block.
But for Workbook activity no exception captured in Catch block.
In fact, i have a process that works fine most of times… but when excel file is procesed serveral times, it grows. sometimes it change format to cells, when i open file with excel and close it after, the size is reduced a 70% aprox. i think could have a relation with this. but in my case there are not invalid cell initial position…
In the next version of the Excel activity package 2.10, trying to save to the A0 range will result in an exception rather than writing over the entire column.
