Excel: Worksheet count and Row count HARDCODED.

How do I NOT hardcoded the worksheet count and row count?

Here is my code:

    Dim excApp As Excel.Application
    Dim excWrk As Excel.Workbook
    Dim excWrkNew As Excel.Workbook
    Dim h, i, j, tmpCtr As Integer
    Set excApp = New Excel.Application
    excApp.Visible = True
    Set excWrk = excApp.Workbooks.Open(txtFilename.Text)
   
    Set excWrkNew = excApp.Workbooks.Add
    Dim tmpStrBG As String
    Dim tmpStrCat As String
    Dim tmpStrIss As String
    Dim tmpStrStra As String
    Dim tmpStrAct As String
    Dim tmpStrWho As String
    Dim tmpStrDue As String
    Dim x As Integer
    tmpCtr = 0
    x = 0
    For h = 2 To 7
        tmpStrBG = excApp.Workbooks(1).Worksheets(h).Cells(6, 7) & " "
        For i = 9 To 19
            If i = 9 And h = 2 Then
                excWrkNew.ActiveSheet.Cells(i - 8, 1) = "Category"
                excWrkNew.ActiveSheet.Cells(i - 8, 2) = "Issue/Information"
                excWrkNew.ActiveSheet.Cells(i - 8, 3) = "Actions"
                excWrkNew.ActiveSheet.Cells(i - 8, 4) = "Who"
                excWrkNew.ActiveSheet.Cells(i - 8, 5) = "Status"
                excWrkNew.ActiveSheet.Cells(i - 8, 6) = "Due Date"
            ElseIf i = 9 Then
                'Do nothing
            Else
                For j = 2 To 7
                    If j = 2 Then
                        tmpStrCat = excApp.Workbooks(1).Worksheets(h).Cells(i, j) & " "
                    ElseIf j = 3 Then
                        tmpStrIss = tmpStrIss & excApp.Workbooks(1).Worksheets(h).Cells(i, j) & " "
                    ElseIf j = 4 Then
                        tmpStrStra = tmpStrStra & excApp.Workbooks(1).Worksheets(h).Cells(i, j) & " "
                    ElseIf j = 5 Then
                        tmpStrAct = excApp.Workbooks(1).Worksheets(h).Cells(i, j) & " "
                    ElseIf j = 6 Then
                        tmpStrWho = excApp.Workbooks(1).Worksheets(h).Cells(i, j) & " "
                    ElseIf j = 7 Then
                        tmpStrDue = excApp.Workbooks(1).Worksheets(h).Cells(i, j) & " "
                    End If
                Next
                If tmpStrCat <> " " Then
                    If h = 2 Then
                        If cboBMR.ListIndex = 1 Then
                            excWrkNew.ActiveSheet.Cells(i - 8, 1) = tmpStrBG & tmpStrCat
                            excWrkNew.ActiveSheet.Cells(i - 8, 2) = tmpStrIss & tmpStrStra
                        Else
                            excWrkNew.ActiveSheet.Cells(i - 8, 1) = tmpStrBG
                            excWrkNew.ActiveSheet.Cells(i - 8, 2) = tmpStrCat & tmpStrIss & tmpStrStra
                        End If
                        excWrkNew.ActiveSheet.Cells(i - 8, 3) = tmpStrAct
                        excWrkNew.ActiveSheet.Cells(i - 8, 4) = tmpStrWho
                        excWrkNew.ActiveSheet.Cells(i - 8, 5) = "Open"
                        excWrkNew.ActiveSheet.Cells(i - 8, 6) = tmpStrDue
                        x = i
                    Else
                        If cboBMR.ListIndex = 1 Then
                            excWrkNew.ActiveSheet.Cells(tmpCtr + i - 9, 1) = tmpStrBG & tmpStrCat
                            excWrkNew.ActiveSheet.Cells(tmpCtr + i - 9, 2) = tmpStrIss & tmpStrStra
                        Else
                            excWrkNew.ActiveSheet.Cells(tmpCtr + i - 9, 1) = tmpStrBG
                            excWrkNew.ActiveSheet.Cells(tmpCtr + i - 9, 2) = tmpStrCat & tmpStrIss & tmpStrStra
                        End If
                        excWrkNew.ActiveSheet.Cells(tmpCtr + i - 9, 3) = tmpStrAct
                        excWrkNew.ActiveSheet.Cells(tmpCtr + i - 9, 4) = tmpStrWho
                        excWrkNew.ActiveSheet.Cells(tmpCtr + i - 9, 5) = "Open"
                        excWrkNew.ActiveSheet.Cells(tmpCtr + i - 9, 6) = tmpStrDue
                        x = i
                    End If
                   
                    tmpStrCat = ""
                    tmpStrIss = ""
                    tmpStrStra = ""
                Else
                    tmpStrCat = ""
                    tmpStrIss = ""
                    tmpStrStra = ""
                End If
            End If
        Next
        If h = 2 Then
            tmpCtr = x - 8
        Else
            tmpCtr = tmpCtr + x - 9
        End If
    Next
   
    excWrkNew.ActiveSheet.Name = "star_upload"
    excWrkNew.SaveAs App.Path & "\" & txtSaveAs.Text
   
    Set excApp = Nothing
    Set excWrk = Nothing
    Set excWrkNew = Nothing

This is working right now as expected.  
However, 7 (worksheet count) and 19 (row count) are hardcoded here.
I don't want the two to be hardcoded values.  How do I do it?

Thanks.
