Calculation time for these functions is proportionate to the number of cells covered, so attempt to decrease the series of cells that the features are referencing. Use the wildcard characters (any kind of solitary character) and (no character or any type of number of characters) in the standards for alphabetical ranges as component of the,,,, as well as other features.

Rather than knotting with cells one by one to obtain or establish a value, obtain or establish the worths in the whole range of cells in one line, using a variant containing a two-dimensional array to shop worths as required.

The complying with code example shows non-optimized code that loops through cells individually to obtain and establish the worths of cells A1: C10000. These cells don't contain solutions. Dim Data, Variety as Array Dim Irow as Long Dim Icol as Integer Dim My, Var as Dual Set Data, Range=Variety("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 * useful content Myvar' Write the worths back into the Excel grid 30,000 times. Information, Variety(Irow, Icol)=My, Var End If Next Icol Next Irow The adhering to code instance shows enhanced code that uses a range to obtain and establish the worths of cells A1: C10000 all at the exact same time. These cells don't include solutions.

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

Value2 = Data, Range returns the formatted value of a cell.
