As opposed to looping through cells individually to get or establish a value, obtain or set the worths in the whole array of cells in one line, using a variant including a two-dimensional variety to store worths as required.


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

What Does Excel Links Not Working Do?

My, Var=My, Var * Myvar' Write the values back into the Excel grid 30,000 times. Data, Array(Irow, Icol)=My, Var End If Following Icol Next Irow The adhering to code example reveals optimized code that makes use of a variety to get and also set the values of cells A1: C10000 all at the exact same time. These cells do not contain formulas.


Information, Range = Variety("A1: C10000"). Value2 For Irow = 1 To 10000 For Icol = 1 To 3 My, Var = Information, Range(Irow, Icol) If My, Var > 0 Then' Adjustment the worths in the variety. My, Var=My, Var * Myvar Information, Array(Irow, Icol) = My, Var End If Next Icol Next Irow' Write all the values back into the array helpful resources at the same time.


Value2 = Data, Variety returns the formatted value of a cell. This is slow-moving, can return ### if the individual zooms, as well as can lose accuracy. returns a VBA currency or VBA day variable if the more info here variety was formatted as Day or Currency. This is slow, can lose precision, and also can cause errors when calling worksheet features.
