Search for a match, copy entire row, and paste to corresponding - excel

Question

Col B on "Sheet2" contains 370 rows of data.
Starting with "Sheet2" Cell B1, I want to search for a matching value in Col B on "Sheet1" (it could be located anywhere in the first 300 rows of "Sheet1" Col B).
If a match is found, copy the entire row from "Sheet1" and paste to Row1 on "Sheet2". Then, move to "Sheet2" Cell B2 and repeat the search, this time pasting the entire row from "Sheet1" to Row2 on "Sheet2". Continue moving thru the entire column of data on "Sheet2", searching for each cell's value on "Sheet1". If a search doesn't return a match, then do not paste anything to that row on "Sheet2" and just proceed to search for the next cell on "Sheet2". (For example, if Sheet1 Col B doesn't contain a match for Sheet2 Cell B3, then nothing gets pasted in Sheet2 Row3.)
I have found the following example, which starts to help me, but it specifies the search value and doesn't loop thru the entire column of values like I am attempting to do.
Sub CopyYes()
Dim c As Range
Dim j As Integer
Dim Source As Worksheet
Dim Target As Worksheet
' Change worksheet designations as needed
Set Source = ActiveWorkbook.Worksheets("Sheet1")
Set Target = ActiveWorkbook.Worksheets("Sheet2")
J = 1 ' Start copying to row 1 in target sheet
For Each c In Source.Range("E1:E1000") ' Do 1000 rows
If c = "yes" Then
Source.Rows(c.Row).Copy Target.Rows(j)
j = j + 1
End If
Next c
End Sub

Answer 1

This should do the trick, and do it fast:
Option Explicit
Sub CopyYes()
'You need Microsoft Scripting Runtime library under Tools-References for this
Dim arrPaste As Variant: arrPaste = Sheet2.UsedRange.Value
Dim arrCopy As Variant: arrCopy = Sheet1.UsedRange.Value
Dim MyMatches As New Dictionary: Set MyMatches = CreateDictionary(arrCopy)
Dim i As Long
For i = 1 To UBound(arrPaste)
If arrPaste(i, 2) = vbNullString Then Exit For
If MyMatches.Exists(arrPaste(i, 2)) Then PasteData arrPaste, arrCopy, i, MyMatches(arrPaste(i, 2))
Next i
Sheet2.UsedRange.Value = arrPaste
Erase arrCopy
Erase arrPaste
End Sub
Private Function CreateDictionary(arr As Variant) As Dictionary
Dim i As Long
Set CreateDictionary = New Dictionary
For i = 1 To 300
CreateDictionary.Add arr(i, 2), i
Next i
End Function
Private Sub PasteData(arrPaste As Variant, arrCopy As Variant, i As Long, MyMatch As Long)
Dim j As Long
For j = 1 To UBound(arrCopy, 2)
If arrCopy(MyMatch, j) = vbNullString Then Exit For
arrPaste(i, j) = arrCopy(MyMatch, j)
Next j
End Sub

Use Range.Find to search for your matching cell
Use a Union to create a collection of the rows that are found
Once your loop is finished, copy your range all at once if the Union is not empty
Sub Shelter_In_Place()
Dim Source As Worksheet: Set Source = ThisWorkbook.Sheets("Sheet1")
Dim Target As Worksheet: Set Target = ThisWorkbook.Sheets("Sheet2")
Dim Found As Range, lr As Long
Dim CopyMe As Range
lr = Target.Range("B" & Target.Rows.Count).End(xlUp).Row
For i = 1 To lr
Set Found = Source.Range("B:B").Find(Target.Range("B" & i), LookIn:=xlWhole)
If Not Found Is Nothing Then
If Not CopyMe Is Nothing Then
Set CopyMe = Union(CopyMe, Target.Range("B" & i))
Else
Set CopyMe = Target.Range("B" & i)
End If
End If
Set Fouund = Nothing
Next i
If Not CopyMe Is Nothing Then
CopyMe.EntireRow.Copy
Source.Range("A1").PasteSpecial xlPasteValues
End If
End Sub
