How to set values for all columns except one?

由 妖精的绣舞 提交于 2019-12-14 02:29:36
问题 My code works great, all it does is take events from a spreadsheet and creates them on google calendar. However, one of the columns in my spreadsheet contains a formula. Everytime I run the code, the formula disappears and is replaced by whatever is on that cell at the time. I know this is where the issue is: // Record all event IDs to spreadsheet except for row 7 range.setValues(data); How can you write a loop to only apply this from row[0] to row[8] but skipping row [7]? But here is the

The data I want to "push" is populated by other code, resulting in a single row of data in a sheet called TempData. The data exists in range TempData!A2:U2. My goal is

Using an array's SetValue method vs. the [] indexers

由 守給你的承諾、 提交于 2019-12-06 20:19:01
问题 I noticed that arrays have the SetValue method, which seems a little out of place when you could just use the indexers. Is there some special purpose for SetValue? The MSDN article didn't seem to say what SetValue was for, just how to use it. Which method would be more efficient to use as far as speed goes? 回答1: Sometimes all you have of an array is that it's an Array . The Array class does not have indexers, so the best way to set/get element values on it is via the GetValue and SetValue
