I am new to vba and need some help please. I have a function whose role is to write to a cell a text value depending on a certain condition.
'input to the function will be a string obtained from a combobox within a userform. The Rowarray is an array of 53 cells with values of either "1's" or "".
Function State(ID As String, Rowarray() As String)
Dim ws As Worksheet
Dim Rej As String
Dim Vir As String
Dim Result As Variant
Dim Rng
Dim Rngrow As Integer
Dim Arr
Set ws = ThisWorkbook.Worksheets("Temp")
Set Rng = ws.Columns(5).Find(ID).Address 'obtains the address of a cell with a value matching the combobox value.
Rngrow = ws.Range(Rng).row 'Obtains the row number from address above
Rej = "R"
Vir = "V"
Arr = Rowarray()
Result = ws.Cells(Rngrow, 6).Value 'this cell is where output is to be placed - one column adjacent to the ID cell (same row)
'conditional statements determining what goes into result cell
If Len(Arr) >= 1 Then
Result = Rej
ElseIf Len(Arr) < 1 Then
Result = Vir
Else
Result = Vir
End If
End Function
Since the array 'Arr' will only have values of "1's" or "", the condition tests whether the array will have anything in it at all. If one element of the array is occupied by a "1" - the result is Rej. Only if all the elements of the array 'Arr' contain "" do I want the result to be Vir.
My problem is that the function is not writing to the 'Result' cell. Is there anything that I am doing wrong? Is my problem with how excel arrays read "" strings?
Any help appreciated.
Your function never writes to the result cell because you actually never tell it to write to the cell.
This line Result = ws.Cells(Rngrow, 6).Value
only sets the variable Result to the value existing in the specific cell at the time the code is run.
Your If
block then just resets the Result
variable.
See the below code, which I think is more in line with what you want. I added code to loop through the array and check for 1
, and then set the value in the result cell based on what's in the array. I also added better variable qualifying to match types. I also made this a Sub
since it does not return any value, like a Function
would.
Sub State(ID As String, Rowarray() As String)
Dim ws As Worksheet
Dim Rej As String, Vir As String
Dim Rng As Range
Dim Rngrow As Integer
Dim Arr() As String
Set ws = ThisWorkbook.Worksheets("Temp")
Set Rng = ws.Columns(5).Find(ID) 'obtains the cell with a value matching the combobox value.
If Not Rng Is Nothing Then
Rngrow = Rng.Row 'Obtains the row number from range above
Rej = "R"
Vir = "V"
Arr() = Rowarray()
Dim l As Long, bRej As Boolean
For l = LBound(Arr) To UBound(Arr)
If Arr(l) = "1" Then
ws.Cells(Rngrow, 6).Value = Rej
bRej = True
Exit For
End If
Next
If Not bRej Then ws.Cells(Rngrow, 6).Value = Vir
Else
ws.Cells(Rngrow, 6).Value = "id not found"
End If
End Sub
One more note, I looped through the array because each array has an element. Even if that element = ""
. So you cannot just use Len(Arr) to test the whole case. You have to test each element in the array against your criteria.
