Question

VBA newbie over here. I’m trying to use an array formula through excel vba but I can’t seem to specify a dynamic range for the formula. I have:

Range("xyz").FormulaArray = "=somefunction(Data!RC:R[8]C[49])"

But next time it could be

Range("xyz").FormulaArray = "=somefunction(Data!RC:R[15]C[32])"

This doesn’t seem to work. Is there any solution to this?

Answer 1

If by dynamic range you mean a range whose size is determined by VBA variables (for instance jRow and kCol) then

Range("xyz").FormulArrayR1C1 = "=somefunction(Data!RC:R[" _
                    & cstr(jRow) & "]C[" & cstr(kCol) & "])"

If you are asking how to determine how many rows and columns in an area are occupied look at

Range.CurrentRegion
Range.CurrentArray
Range.End(xlUp).Row  (also xlDown, xlRight, xlLeft)
