将数据传输到VBA中后，在动态范围内查找和替换空白单元格

Question

Okay I know there are multiple questions similar to this, but at least from what I've found, my problem is different so please bear with me. I am building a user form that allows users to input data into a tracking sheet, but there are certain scenarios where only part of the data will get submitted at a time,leaving "holes" in the tracking sheet. My goal is to fill these "holes" with a period so that way relevant data will stay together in the same row instead of getting bumped up into those holes.

Sheets("Tracker").Activate
Worksheets("Tracker").Columns("A:J").Replace What:="", Replacement:=".", _
    SearchOrder:=xlByColumns, MatchCase:=False

I realize I am essentially telling excel to fill columns A through J with a period, so my question is, is there an easier way to do this, or a way to specify that I only need the most recent row to contain the periods?

Update: This is the code I am using to find the next available row in the tracker for new data to go. Thus when portions of the previous row are missing, the macro fills those unused cells with the next rows data.

Set ws = Sheets("Tracker") Sheets("Tracker").Select 
ws.Range("E" & LastRow).Value = job_txtb.Text    
'Finds the last blank row
LastRow = ws.Range("A" & ws.Rows.Count).End(xlUp).Row + 1 
'Adds the Job name Code into Col E & Last Blank Row

Answer 1

The following will give you the first unused row. I don't understand why periods would be necessary.

With ActiveSheet
    On Error Resume Next
    lastRow = .Cells.Find("*", .Cells(.Cells.Count), xlFormulas, _
    xlWhole, xlByRows, xlNext).Row
    If Err <> 0 Then lastRow = 0
End With
firstUnusedRow = lastRow + 1

Range("A" & firstUnusedRow).Value = Textbox1.Value
Range("B" & firstUnusedRow).Value = Textbox2.Value
Range("C" & firstUnusedRow).Value = Textbox3.Value
'etc.
'etc.,,
