Choose from Excel dropdown programmatically - vba

Question

I want to write a macro that will pick a particular value (in my case, stored in cell A1) from a dropdown list (in my case, in cell D6).
Here's what I have so far:
sr_par2 = Array ("TEXT", 'TEXT2", "TEXT3")
sr = Range("A1").Value
(...)
Dim i As Integer
i = 0
Range("D6").Select
Do While (sr <> ActiveCell.FormulaR1C1)
Range("D6").Select
ActiveCell.FormulaR1C1 = sr_par2(i)
i = i + 1
Loop

Answer 1

Is this what you are trying? I have commented the code so that you will not have a problem understanding it. Still if you do then simply ask :)
Sub Sample()
Dim ws As Worksheet
Dim rngIn As Range, rngOut As Range
Dim MyAr
Dim sFormula As String
Dim i As Long
'~~> Replace this with the relevant worksheet
Set ws = ThisWorkbook.Sheets("Sheet1")
With ws
'~~> Set your input and output range here
Set rngIn = .Range("A1")
Set rngOut = .Range("D6")
'~~> Get the validation list if there is one
On Error Resume Next
sFormula = rngOut.Validation.Formula1
On Error GoTo 0
If sFormula = "" Then
'~~> If no validation list then directly populate the value
rngOut.Value = rngIn.Value
Else
'validation list TEXT1,TEXT2,TEXT3
MyAr = Split(sFormula, ",")
'~~> Loop through the list and compare
For i = LBound(MyAr) To UBound(MyAr)
If UCase(Trim(rngIn.Value)) = UCase(Trim(MyAr(i))) Then
rngOut.Value = MyAr(i)
Exit For
End If
Next i
'~~> Check if the cell is still blank. If it is then it means that
'~~> Cell A1 has a value which is not part of the list
If Len(Trim(rngOut.Value)) = 0 Then
MsgBox "The value in " & rngOut.Address & _
" cannot be set as the value you are copying is not part of the list"
End If
End If
End With
End Sub

If I understood correctly, this should do what you want :
sr_par2 = Array("TEXT", "TEXT2", "TEXT3")
sr = Range("A1").Value
Dim i As Integer
i = 0
On Error GoTo Handler
Do While (sr <> sr_par2(i))
i = i + 1
Loop
Range("D6").FormulaR1C1 = sr_par2(i)
Exit Sub
Handler:
MsgBox "Value not in the list", vbCritical + vbOKOnly, "Value not found"
