VBA Evaluate Range and VLOOKUP
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. (
the following simplified example File (XL2007 .xlsm)
has a Spreadsheet LEFT
Function and a Spreadsheet VLOOKUP Function
The results look good!
(That is to say wot I expect!) :-

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)

Re: VBA Evaluate Range and VLOOKUP
Interesting question.
First, the way I'd do it would be, for ex., using your formula
With rngCC
.Formula = "=VLOOKUP(" & rngName(1, 1).Address(0, 0) & ",$A$16:$C$33,3,FALSE)"
.Value = .Value
or calling VlookUp() in vba:
rngCC = Application.WorksheetFunction.VLookup(rngName, Range("A16:C33"), 3, False)

I can give you my take on this.
The way I see it, you are not getting the results you want simply because they are not there.
The "if(row()" or "if(column()" workarounds in the Evaluate do not create answers, they just remind the vba Evaluate() to get all the results that the formula in the worksheet returns and not just one.
If the results are not there you cannot get them.
I'll try to explain what I mean with 2 examples.
Example 1 - the evaluation of the formula returns an array
Some formulas may return an array when you evaluate them in the worksheet but when you use Evaluate() in vba you just get 1.
An example. Let's say B1 holds a Text value and B2 a number value. Write in A1:
=ISTEXT(B1:B2)
Although you only get in the cell 1 result (True/False), you are examining 2 cells, and if in the formula bar you select the formula and press F9 you see that the result is, in fact, the array {TRUE;FALSE}. You are seeing 1 result in the worksheet cell but the formula generated an array with 2 results.
Now if in vba you use:
Dim v As Variant
v = Evaluate("ISTEXT(B1:B2)")
If you execute this statement and inspect v you'll see that it is Variant/Boolean with the value True.
In this case you already saw in the worksheet that the formula returns an array. To tell Evaluate() to loop through the range you use the "if(row()". This way, since row() always returns an array, Evaluate() will go through all the values.
Dim v As Variant
v = Evaluate("IF(ROW(B1:B2),ISTEXT(B1:B2))")
Now if you inspect v you see it's a Variant/Variant(1 to 2, 1 to 1) and you get the array with the values True and False
The "if(row()" did not create the other result, it just helped bringing it back.
Example 2 - the evaluation of the formula does not return an array, it returns a simple value
This is the case for ex. of
=VLOOKUP(A1:A2,B1:C3,2,FALSE)
Now if you add this formula to a cell with some values in A1:A2 and B1:C3 you'll see 1 value in the cell.
If you now do as in the previous example and select the formula in the formula bar and press F9 you'll see that the formula only returns that 1 value. It does not return an array although you might think it would since the first parameter is an array.
Now this is my point. When, like in this case, the formula does not return an array there's no use in Evaluating in vba using the "If(Row()".
There is no other value to get. You'll just get the same value twice
If you try:
Dim v As Variant
v = Evaluate("=VLOOKUP(A1:A2,B1:C3,2,FALSE)")
v = Evaluate("=IF(ROW(A1:A2),VLOOKUP(A1:A2,B1:C3,2,FALSE))")
and inspect v after each Evaluate() statement you'll see that exactly.
Notice that this would also be valid for others formula, like:
=INDEX(A1:A3,{1;3;2},1)
Also in this case the same as with the VLookUp(). If you evaluate the formula in the worksheet in the formula bar with F9 you see that there is only 1 value returned from the formula, so there's no point in using the If(row() in vba. You'll just get the same value thrice.
Conclusion:
If the formula evaluated in the worksheet returns an array of values but in vba is only returning 1 value, you can use "if(row()" or "if(column()" bits to tell vba to get all the results.
If the formula evaluated in the worksheet returns only 1 value that's all you can get
Remark: I don't mean by this that the formulas could not return more than one value, they could if used as array formulas that return an array, or using some workaround, but not as simple native formulas inserted directly in a cell like we did in these examples.

This has been a learning exercise for me (Which maybe I tried to take a (5th) bridge too far for my beginner?s competence by looking at a further 5th Evaluate method!!). This thread followed on from thread
where the third method kindly suggested by Jerry Sullivan follows very closely your method suggested in the above code.
Sub Test3UsingR1C1JerrySullivan() 'enters R1C1 formula into results range then converts formulas to values Dim rngDD As Range
Set rngDD = ThisWorkbook.Worksheets("sheet1").Range("D3:D10")
Dim rngLOOKUP As Range
Set rngLOOKUP = ThisWorkbook.Worksheets("sheet1").Range("$A$16:$C$33")
With rngDD
.FormulaR1C1 = "=VLOOKUP(R[0]C[-3]," & rngLOOKUP.Address(ReferenceStyle:=xlR1C1, External:=True) & ",3,0)"
'Jerry put my exact SVERWEISS formula in!
'. Syntax: FormulaR1C1=" here the formula ". The [] makes it relative referrencing.
.Value = .Value 'Removes Formula(Puts value in)
As that was my very first experience with the .Formula RC stuff, it is very helpful again to see a slightly different version of this method. A great helper again in my learning. Thanks!

…. Workaround to get my VLOOKUP to return an array!
As you may know, functions like Index() and Vlookup() that seem to return only 1 value (when evaluated in the formula bar), can, in fact, return an array of values when used as an array formula that returns an array applied to a range of cells.
For ex, in post #6, if you use the VLookUp() as an array function that returns an array, like
- select B3:B5
- in the formula bar paste: =VLOOKUP(A3:A5,$A$16:$C$33,3,FALSE)
- confirm with Control-Shift-Enter
You'll see that the 3 correct results are returned. That's how VLookUp() behaves when applied as an array formula that spans more than 1 cell.
This means that although when you evaluate the VLookUp() you only see 1 result, the other results are somehow possible to be generated.
The workaround I was thinking was one published by XOR LX article here:
where he presents a workaround for the case of these functions like Index() and Vlookup() that seem to return only 1 value (when evaluated in the formula bar), but that in fact can return an array of values when used as an array formula that returns an array applied to a range of cells.
This is, of course, very interesting as a learning experience, but I would not forget the simplest solution. Writing the formula in the cells and let excel evaluated it, like
With range
.Formula = someformula
.Value = .Value
... simple and easy to read and understand.
&ABCDEFG1Produnt&&&&&&2Name&&&&&&3Chocolate-europe aroma4&&&Choc&4Chocolate-Cookies0&&&Choc&5Banana-Chocolate-Split10&&&Bana&6&&&&&&& [Book1]Sheet1
AddrFormula[Book1]Sheet1B3:B5 =VLOOKUP(A3:A5,$A$16:$C$33,3,FALSE)
This in an array formula that is returning an array. Select the WHOLE range, paste the formula into the formula bar
and confirm with CTRL+SHIFT+ENTER and not just ENTER
likes this.

Actually PGC the technique I outline there is neither for applying over a range of cells, nor is it even an array formula.
It is rather a method by which we can use a single-cell, non-array formula to generate an array of returns to be passed to some function, e.g. INDEX, VLOOKUP, which "normally" do not behave as such.
So as in one of my examples there, something like:
=MAX(VLOOKUP(T(IF(1,{"A","B","C"})),J1:K10,2,0))
which gives the maximum value in K1:K10 where the corresponding row entry in J1:J10 is the first occurrence in that range of either "A", "B" or "C", is a single-cell formula which resolves to:
=MAX(VLOOKUP({"A","B","C"},J1:K10,2,0))
which is e.g.:
=MAX({1,2,4})
where the VLOOKUP has been coerced into operating over an array of values.
Hope that clarifies things a bit!

Re: VBA Evaluate Range and VLOOKUP
Sorry I think (or, in this case, I know
)I did not make myself clear.
Your workaround is not needed if you apply the formula over a range of cells.
Like in the example I posted in post #8, if we apply the formula over a range of cells there's no need to use any workaround, the formula works fine directly.
Alan's problem is that he wants to use vba Evaluate() to get those "other" values that you'd get directly if the formula was used on a range of cells.
There's where your workaround comes handy.
Using your workaround you can get from a formula in a single cell all the results that you'd get using the formula directly over a range of cells.
This means that this way we can use it in Evaluate() to get all the results and that solves Alan's problem.
For my example in post #8, using your workaround in the VLookUp() formula that I used in cells B3:B5, we can get all the results in the Evaluate().
Hope it's clearer now.
Kind regards
