Delete rows with based on cell value - vba

Question

I'm trying to search Column A in Sheet2 for the value of A1 in Sheet1.
If it exists, I'd like to delete the whole row in Sheet2.
If it doesn't exist, I'd like the message box to open.
Here's what I have, but I'm struggling with actually deleting the row:
Sub Delete_Rows()
Dim FindString As String
Dim Rng As Range
FindString = Sheets("Sheet1").Range("A1")
If Trim(FindString) <> "" Then
With Sheets("Sheet2").Range("A:A")
Set Rng = .Find(What:=FindString, _
After:=.Cells(.Cells.Count), _
LookIn:=xlValues, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlNext, _
MatchCase:=False)
If Not Rng Is Nothing Then
'I can't figure out how to delete the row
Else
MsgBox "Not Found"
End If
End With
End If
End Sub

Answer 1

Here is an example based on THIS
You don't need to loop. You can use .Autofilter which is faster than looping.
Sub Sample()
Dim ws1 As Worksheet, ws2 As Worksheet
Dim delRange As Range
Dim lRow As Long
Dim strSearch As String
Set ws1 = Sheet1: Set ws2 = Sheet2
strSearch = ws1.Range("A1").Value
With ws2
'~~> Remove any filters
.AutoFilterMode = False
lRow = .Range("A" & .Rows.Count).End(xlUp).Row
With .Range("A1:A" & lRow)
.AutoFilter Field:=1, Criteria1:="=" & strSearch
Set delRange = .Offset(1, 0).SpecialCells(xlCellTypeVisible).EntireRow
End With
'~~> Remove any filters
.AutoFilterMode = False
End With
If delRange Is Nothing Then
MsgBox "Not Found"
Else
delRange.Delete
End If
End Sub

Here is the code to :
loop through all the values in Column A of Sheet1,
look for all matches (with FindNext method) in Column A of Sheet 2
and delete the rows that matches
Give it a try :
Sub test_user5472539()
Dim Ws1 As Worksheet, _
Ws2 As Worksheet, _
LastRow As Long, _
FindString As String, _
FirstAddress As String, _
cF As Range
Set Ws1 = ActiveWorkbook.Sheets("Sheet1")
Set Ws2 = ActiveWorkbook.Sheets("Sheet2")
LastRow = Ws1.Range("A" & Ws1.Rows.Count).End(xlUp).Row
For i = 1 To LastRow
FindString = Ws1.Range("A" & i)
If Trim(FindString) <> "" Then
Ws2.Range("A1").Activate
With Ws2.Range("A:A")
'First, define properly the Find method
Set cF = .Find(What:=FindString, _
After:=.Cells(1, 1), _
LookIn:=xlValues, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlNext, _
MatchCase:=False, _
SearchFormat:=False)
'If there is a result, keep looking with FindNext method
If Not cF Is Nothing Then
FirstAddress = cF.Address
Do
cF.EntireRow.Delete
Set cF = .FindNext(cF)
'Look until you find again the first result
Loop While Not cF Is Nothing And cF.Address <> FirstAddress
Else
MsgBox "Not Found"
End If
End With
Else
End If
Next i
End Sub
