Rather of knotting through cells one by one to obtain or set a worth, get or establish the worths in the entire series of cells in one line, using a variant having a two-dimensional array to shop values as required.

The adhering to code instance shows non-optimized code that loopholes with cells one at a time to get and also set the worths of cells A1: C10000. These cells don't contain formulas. Dim Data, Variety as Variety Dim Irow as Long Dim Icol as Integer Dim My, Var as Dual Establish Information, Array=Range("A1: C10000") For Irow=1 to 10000 For icol=1 to 3' Read the values from the Excel grid 30,000 times.

My, Var=My, Var * Myvar' Compose the worths back into the Excel grid 30,000 times. Data, Range(Irow, Icol)=My, Var End If Next Icol Next Irow The adhering to visit this page code instance reveals enhanced code that uses an array to obtain and also set the worths of cells A1: C10000 all at the very same time. These cells do not have solutions.

Data, Range = Array("A1: C10000"). Value2 For Irow = 1 To 10000 For Icol = 1 To 3 My, Var = Information, Range(Irow, Icol) If My, Var > 0 After That' Modification the values in the array. My, Var=My, Var * Myvar Information, Variety(Irow, Icol) = My, Var End If Next Icol Next Irow' Write all the worths back into the range at as soon as.
