Excel stop updating calculation
If in B1 you enter =Evaluate If("2*A1", C1) then when C1 contains =True() B1 updates with A1 but if C1 has =False() then B1 stays frozen.
For the second function, if in B2 you enter =Freeze After("A1*2", C2) and if in C2 you have something like 6/25/2015 PM then the formula in B2 will update with A1 prior to PM but will remain frozen afterwards. VBA) I suspect that the non-VBA is probably more efficient and possibly more reliable (I haven't tested the VBA approach with a wide variety of functions).
You can use Solver when you need to find the optimum value for a particular cell by adjusting the values of several cells or when you want to apply specific limitations to one or more of the values in the calculation.
It defines two worksheet functions which can selectively either evaluate formulas in a cell or freeze them, depending on the condition: Function Evaluate If(expression As String, condition As Boolean) As Variant Application. Text If Is Numeric(my Text) Then my Val = Val(my Text) Else my Val = my Text End If End If Evaluate If = my Val End Function Function Freeze After(expression As String, deadline As Date) As Variant Application.For example, if two cells each contain the value 10.005 and the cells are formatted to display values in currency format, the value .01 is displayed in each cell.If you add the two cells together, the result is .01 because Excel adds the stored values 10.005 and 10.005, not the displayed values.On the other hand -- enabling circular references could potentially cause problems (it isn't turned off by default for no reason). I simply added two timestamp cells containing the @NOW() function, formatted to display time. I then copy paste special to the correct cell keeping values and source formatting.Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
