如何使用 VBA 根据值和 combobox 选择填充 excel 中的行？

Question

I am a beginner with VBA and I have a schedule (screenshot below) that i am trying to alter using a userform.

I have a Userform with 3 comboboxes, 1 for the type of procedure to be performed and then 1 for the start time and another for the end time (these times are based off the first row in the screenshot).

I want to essentially alter the spreadsheet for a specific procedure using the userform. For example, lets say i want to change procedure 7 to last from 2:00 until 19:00. In a case like that then i would want to see all the rows that have 7 in them to be filled in with 7 under those columns (see result screenshot)

All i have is code to find which rows contain a certain value and then that value is offset... but i honestly dont know where to go from here... Any help is greated appreciated!!!

Dim c As Range
Dim firstAddress As String

Count = 7

With Sheet49.Range("AA7:AA636")
    Set c = .Find(7, LookIn:=xlValues)
    If Not c Is Nothing Then
        firstAddress = c.Address
        Do While Not c Is Nothing
            Count = Count + 1
            c.Offset(, -8).Value = c.Value
            Set c = .FindNext(c)
            If Count = 636 Then
            Exit Do
            End If
        Loop
    End If
End With

i want to change procedure 7 to last from 2:00 until 19:00. In a case like that then i would want to see all the rows that have 7 in them to be filled in with 7 under those columns

Logic:

1. Find the start and end time columns
2. Find the relevant procedure and then fill the entire range in 1 go!

Code:

Option Explicit

Sub Sample()
    Dim ws As Worksheet
    Dim ColA As Long, ColB As Long
    Dim aCell As Range, bCell As Range
    Dim i As Long
    
    '~~> I am hardcoding these values. Pick them up from combobox
    Dim ProcToFind As Long: ProcToFind = 7
    Dim StartTime As String: StartTime = "2:00"
    Dim EndTime As String: EndTime = "19:00"
    
    '~~> Change this to the relevant sheet
    Set ws = Sheet1
    
    With ws
        '~~> Find the start and end time columns
        '~~> Hardcoded 21. Replace with last column
        For i = 1 To 21
            Select Case TimeValue(Format(.Cells(1, i).Value, "hh:mm:ss"))
                Case TimeValue(StartTime): ColA = i
                Case TimeValue(EndTime): ColB = i
            End Select
        Next i
        
        If ColA = 0 Or ColB = 0 Then
            MsgBox "Unable to find start or end time column(s)"
            Exit Sub
        End If
        
        Set aCell = .Cells.Find(What:=ProcToFind, LookIn:=xlValues, _
                    LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
                    MatchCase:=False, SearchFormat:=False)

        If Not aCell Is Nothing Then
            Set bCell = aCell
            
            '~~> Fill the entire range in 1 go
            .Range(.Cells(aCell.Row, ColA), .Cells(aCell.Row, ColB)).Value = ProcToFind
            
            Do
                Set aCell = .Cells.FindNext(After:=aCell)

                If Not aCell Is Nothing Then
                    If aCell.Address = bCell.Address Then Exit Do
                    
                    '~~> Fill the entire range in 1 go
                    .Range(.Cells(aCell.Row, ColA), .Cells(aCell.Row, ColB)).Value = ProcToFind
                Else
                    Exit Do
                End If
            Loop
        End If
    End With
End Sub
