how to find multiple strings using range.value? - excel

Question

i tried to use range("A1:I1").value to find multiple strings at the first row however it shows that error "mismatch". What have i done wrong here? Is there another way to do it?
Dim sht as worksheet
Set sht = ThisWorkbook.Sheets("Result")
If sht.range("A1:I1").value = " Voltage" and sht.range("A1:I1").value = " Time" ,<---------error 'mismatch' occurs here
call powerandtime

Answer 1

The problem here is that you are comparing an array of values against a single value. In case of such a small array you can make use of some Application.Methods. Another option would be to use Range.Find on the actual Range object. I'll demonstrate both below:
Application.Methods
Sub Test()
Dim ws As Worksheet: Set ws = ThisWorkbook.Worksheets("Result")
Dim arr As Variant
With Application
arr = .Transpose(ws.Range("A1:I1").Value)
If .Count(.Match(Array("Voltage", "Time"), arr, 0)) = 2 Then
Call PowerAndTime
End If
End With
End Sub
What happens here is that .Match will return an array of two elements. It will either return an error value to the array if either "voltage" or "time" is not found, or it would return a numeric value when either one of them is found. Then .Count will count numeric values within that returned array, and only if the count would be 2, is when both values are present within your initial range.
Note: .Match needs a 1D-array, hence the .Transpose at the start.
Range.Find
Sub Test()
Dim ws As Worksheet: Set ws = ThisWorkbook.Worksheets("Result")
Dim rng1 As Range, rng2 As Range
Set rng1 = ws.Range("A1:I1").Find("Voltage", lookat:=xlWhole)
Set rng2 = ws.Range("A1:I1").Find("Time", lookat:=xlWhole)
If Not rng1 Is Nothing And Not rng2 Is Nothing Then
Call PowerAndTime
End If
End Sub
So only when both "Voltage" and "Time" are found as xlWhole values within your specific range, it would continue to call PowerAndTime.

Answer 2

Sub testMatchBis()
Dim sh As Worksheet, rng As Range, voltPos As Long, timePos As Long
Dim rngBis As Range, arrBis as Variant
Set sh = ActiveSheet ' use please your sheet here
Set rng = sh.Range("A1:I1")
voltPos = IsMatch(rng, "Voltage")
timePos = IsMatch(rng, "Time")
If voltPos <> 0 And timePos <> 0 Then
Set rngBis = sh.Columns(voltPos)
Set rngBis = Union(rngBis, sh.Columns(timePos))
arrBis = rngBis.Value 'the both columns content will be input in an array
rngBis.Select 'both columns will be selected. Of course, you need to determine
'only part of the comumn keeping values (their last row) and limit the range
'Call call powerandtime 'You must know what this sub must do...
Else
MsgBox "(At least) one of your searched strings could not be found in the range..."
End If
End Sub
Private Function IsMatch(rng As Range, strS As String) As Long
On Error Resume Next
IsMatch = WorksheetFunction.Match(strS, rng, 0)
If Err.Number <> 0 Then
Err.Clear: On Error GoTo 0
IsMatch = 0
End If
On Error GoTo 0
End Function

You could try:
Sub test()
Dim arrStrings As Variant
Dim i As Long, Counter As Long
Dim rng As Range
Set rng = ThisWorkbook.Worksheets("Sheet1").Range("A1:I1")
Counter = 0
arrStrings = Split("Time,Electric", ",")
For i = LBound(arrStrings) To UBound(arrStrings)
If Not rng.Find(arrStrings(i), lookat:=xlWhole) Is Nothing Then
Counter = Counter + 1
GoTo NextIteration
End If
NextIteration:
Next i
If Counter = UBound(arrStrings) + 1 Then
Call PowerAndTime
End If
End Sub
