Hi,
As a beginner I may be going a bit above my head!!

After studying and participating at some considerable length in Threads and links to do with using the Evaluate function to speed things up, I thought I understood it. Here are some of those links and Threads. (www.excelfox.com/forum/f22/concatenating-balls-1891/ VBA Trick of the Week :: Avoid Loop for Range Calculations – Evaluate | Useful Gyaan )

. So … the following simplified example File (XL2007 .xlsm)
https://app.box.com/s/pr78mhna00advvhsrmvi
has a Spreadsheet LEFT Function and a Spreadsheet VLOOKUP Function

The results look good! (That is to say wot I expect!) :-

D6=LEFT(A6,4)
D7=LEFT(A7,4)
D8=LEFT(A8,4)
D9=LEFT(A9,4)
D10=LEFT(A10,4)




I apply this code

Code:
[color=darkblue]Sub[/color] Evaluate_Left()[color=darkblue]Dim[/color] rngName [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngName = ThisWorkbook.Worksheets("Sheet1").Range("A3:A10")
[color=darkblue]Dim[/color] rngEE [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngEE = ThisWorkbook.Worksheets("sheet1").Range("E3:E10")
[color=darkblue]Let[/color] rngEE = Evaluate("if(row(3:10),LEFT(" & rngName.Address & ",4))")
[color=darkblue]End[/color] [color=darkblue]Sub[/color] [color=green]'Evaluate_Left()[/color]


And get the following:-

[color=darkblue]Set[/color] rngName = ThisWorkbook.Worksheets("Sheet1").Range("A3:A10")
[color=darkblue]Dim[/color] rngCC [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngCC = ThisWorkbook.Worksheets("sheet1").Range("C3:C10")
[color=darkblue]Let[/color] rngCC = Evaluate("if(row(3:10),VLOOKUP(" & rngName.Address & ",$A$16:$C$33,3,FALSE))")
[color=darkblue]End[/color] [color=darkblue]Sub[/color] [color=green]'Evaluate_VLOOKUP()[/color]


…but get the following:-

. I would have expected that result without The extra If Row() stuff, which I thought overcame this problem.
. can anyone suggest wot is going wrong, or how I obtain the correct results (Using the Evaluate Function for a range)
Thanks
Alan.

P.s. I will also post this Thread Here: Multiple Columns Into Single Column Using Data Text To Column - Page 2
 
P. S.

Actually, I just tried your workaround in my example in post #8 and although it worked OK in the worksheet it seems it does not work with vba Evaluate().
Can you confirm this?

Er, sorry. Not much of an expert when it comes to VBA.

Can you confirm what the code is to be used?

This is a simple example.

In D1:

=VLOOKUP(T(IF(1,{"B","A"})),A1:B2,2,0)

If I select the formula in the formula bar and evaluate it (F9) I get, as expected: {5,4}

in vba:

Code:
Sub TestEval()
Dim v As Variant

v = Evaluate("VLOOKUP(T(IF(1,{""B"",""A""})),A1:B2,2,0)")
End Sub

After the Evaluate I inspect v and get just 5 in v, not the array that I wanted.

It doesn't mean it won't work if the VLookUp() is a parameter in a function like Max(), or Average(), but I can't get just the array of values resulting from the VLookUp() like I can when I evaluate the formula in the formula bar.

You just need one of the usual tricks to force the return of an array:
Code:
v = Evaluate("INDEX(VLOOKUP(T(IF(1,{""B"",""A""})),A1:B2,2,0),)")
for instance.

Not sure I want to be maintaining this code though. :)

Interesting. Wonder why it requires the extra coercion when used in VBA?

Because otherwise it's as if you entered it into a cell normally - you only get the first value returned.

Hi pgc ( and XOR LX),

I am very grateful for you both for your further inputs.

………..

This is, of course, very interesting as a learning experience, but I would not forget the simplest solution. Writing the formula in the cells and let excel evaluated it, like

Code:
With range
         .Formula = someformula
         .Value = .Value
End With

... simple and easy to read and understand.

. I agree this may be a satisfactory solution and so the Codes from you and Jerry are very helpful.
. In addition I have now a third alternative from pgc post #8, using a workaround in the VLookUp() formula that was used in cells B3:B5


Code:
[color=darkblue]Sub[/color] Test3cc_pgc()[color=darkblue]Dim[/color] rngName [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngName = ThisWorkbook.Worksheets("Sheet1").Range("A3:A10")
[color=darkblue]Dim[/color] rngCC [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngCC = ThisWorkbook.Worksheets("sheet1").Range("C3:C10")
[color=darkblue]With[/color] rngCC
         .Formula = "=VLOOKUP($A$3:$A$10,$A$16:$C$33,3,FALSE)"
[color=green]'         .Value = .Value[/color]
[color=darkblue]End[/color] [color=darkblue]With[/color]


[color=darkblue]End[/color] [color=darkblue]Sub[/color] [color=green]'Test3cc_pgc()[/color]




. I also think that I may now be going way above my inexperienced beginner’s brain now with trying to use <acronym>vba</acronym> Evaluate() to get all values that you'd get directly if the formula was used on a range of cells.
. Although it is somewhat above my current grasp of VBA I think I have been able to follow your arguments. Possibly naively I was hoping to rap up this very useful learning exercise I could modify my code for putting in the values in C column which only gave the one value:

Code:
[color=darkblue]Sub[/color] Evaluate_VLOOKUP()

[color=darkblue]Dim[/color] rngName [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngName = ThisWorkbook.Worksheets("Sheet1").Range("A3:A10")
[color=darkblue]Dim[/color] rngCC [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngCC = ThisWorkbook.Worksheets("sheet1").Range("C3:C10")
[color=darkblue]Let[/color] rngCC = Evaluate("if(row(3:10),VLOOKUP(" & rngName.Address & ",$A$16:$C$33,3,FALSE) )")
[color=darkblue]End[/color] [color=darkblue]Sub[/color] [color=green]'Evaluate_VLOOKUP()[/color]


..to something of the following from ….


Code:
[color=darkblue]Sub[/color] Evaluate_VLOOKUPpgcXORLX()

[color=darkblue]Dim[/color] rngName [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngName = ThisWorkbook.Worksheets("Sheet1").Range("A3:A10")


[color=darkblue]Dim[/color] rngEE [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngEE = ThisWorkbook.Worksheets("sheet1").Range("E3:E10")
[color=darkblue]Let[/color] rngEE = Evaluate("if(row(3:10),{=VLOOKUP(" & rngName.Address & ",$A$16:$C$33,3,FALSE)} )")
[color=darkblue]Let[/color] rngEE = Evaluate("{=VLOOKUP(" & rngName.Address & ",$A$16:$C$33,3,FALSE)} ")
[color=darkblue]End[/color] [color=darkblue]Sub[/color] [color=green]'Evaluate_VLOOKUPpgcXORLX()[/color]


to put the correct values in the E column.

. As seen below this did not work. Obviously I have stretched my understanding possibly a bit too far here.

. It would be great If either of you could correct this code to give the correct results. Although maybe I am naively missing the point and that is not possible. Sorry if that is the case. Never the less I have learnt a lot from participating in this thread. And I am very grateful to your inputs.


Many thanks again
Alan

P.s. PGC - Your following suggested method (which gives indication if there are array values from the formula available) was very interesting and useful.
. 1) selecting a cell with a formula in it and
. 2) then selecting (Highlighting) that formula in the Formula bar and
. 3) then pressing F9 to see a result of the form {4;0;10;etc} indicating if there are array values from the formula available

. - Can you please tell me which key combination returns the displayed result in the formula window back to the formula?

for instance.

Thanks Rory, that's what was missing.

Not sure I want to be maintaining this code though. :smile:

I agree, but I'm a ****** for understanding how it works, even if I don't plan on using it. :)
