How to use Rows(x:x) .select in IF statement - excel

I have a spreadsheet where I have a macro built to whittle down the amount of data to something manageable. The next step is to compare the value of a column cell to a predefined number determined in the macro and placed in another cell away from the data. If the value is less than the predetermined value, I want to delete the entire row, then go on to the next row and do it again. In the end, all I should have left is the rows where that column is greater than the predetermined value.
Let's say the column is C and the predetermined value is in M1. How would I do this?
BTW, the macro to date has filtered the data based on Column C from largest to smallest, so I'm basically looking to find the first value in C to be less than the other value, then highlight everything underneath and delete it.
Thanks for any help.

You didn't specify if you had a Header row or not, but for your exact request here you go.
Option Explicit
Sub DeleteRows()
Dim ws As Worksheet, myVal As Double
Dim Cell As Range, RngC As Range, CompRng As Range
Set ws = ThisWorkbook.Worksheets(1)
Set RngC = ws.Range("C:C")
Set CompRng = ws.Range("M1")
myVal = CDbl(CompRng.Value)
For Each Cell In RngC
If CDbl(Cell.Value) < myVal Then
Cell.EntireRow.Delete
End If
Next Cell
End Sub

Divide a range of cells with a particular number if cell values are numeric

I have to divide all the cell values of sheet -"Databook" with a number 1000000 only if the cell contains numeric value. It means I have to divide only those cells in the sheet which contains numbers like 17577.2 , 2123, 13979123.22, 239812098321.1, and 9798.
Sub i()
'declare variables
Dim ws As Worksheet
Dim rng As Range
Dim myVal As Range
Set ws = Worksheets("Sheet1")
Set rng = ws.Range("A:Z")
For Each myVal In rng
If IsNumeric(myVal) = True Then
myVal = myVal.Value / 1000000
Else
Next myVal
End Sub
You currently suffer from a missing End If, thus your current code won't run at all. Properly indenting your code would have revealed the issue. I would also recommend not trying to loop all cells in your current range. Note that these are (for Excel 2019 at least) 27.262.976 cells to go through (you might want to first find your range of interest first; last used row, last used column). This many calls will be terribly slow. Limit that numbers by just using the actual numeric values at least.
Try to uitilize SpecialCells. The way it works > <YourRange>.SpecialCells(XlCellType, [XlSpecialCellsValue]). For example:
Sub Test()
Dim ws As Worksheet: Set ws = ThisWorkbook.Worksheets("Sheet1")
For Each cl In ws.Range("A:Z").SpecialCells(2, 1)
cl.Value = cl.Value / 1000000
Next
End Sub
Where: .SpecialCells(2, 1) can also be read as .SpecialCells(xlCellTypeConstants, xlNumbers)
Note: If you have big chunks of cells that contain numeric values it might be beneficial to loop Areas property instead of Cells since you can load these into an array and perform calculations in memory before pasting back these values. This could also save you some valuable runtime.

How do I make a Range of a certain area, that has been filtered out?

So first of all, I wanna write a VBA Code, which allows me to pick a certain range of an Excel sheet, to then copy SOME of the needed values to another worksheet. The issue with this is, that in the Excel sheet of which i take Information from, has some filters applied.
So i found the solution with the method (?) .SpecialCells(xlCellTypeVisible) but the Problem again is, that it works for 1 column, but not for Ranges with more than one column. For Ranges with more than one column, it only picks the first row
Dim rng As Range
Set rng = src.Worksheets("l04").Range(src.Worksheets("l04").Range("Z7:AK7"), src.Worksheets("l04").Range("Z7:AK7").End(xlDown)).SpecialCells(xlCellTypeVisible)
My expected result from this Line of Code should be, that the Range rng is set from Z7 to AK7 all the way down to the maximum number of rows, but only those which are visible.
Edit1: Changed SpecialCell --> SpecialCells
Dim cell As Range
Dim lastRow As Long
With src.Worksheets("104")
lastRow = .Cells(.Rows.Count, "Z").End(xlUp).row
With .Range("Z7:AK" & lastRow)
For Each cell In .Columns(1).SpecialCells(xlCellTypeVisible)
Debug.Print Intersect(.Cells, cell.EntireRow).Address ' change this to what you actually need to grab from each visible cell
Next
End With
End With
Based on some clues in your question, you may find that using the Intersect Method is advantageous.
Dim rng as Range
With src.Worksheets("l04")
'gets all visible cells within the used range on your sheet
set rng = .UsedRange.SpecialCells(xlCellTypeVisible)
'Use the Intersect method to select specific columns
set rng = Intersect(rng, .range("AB:AB, AD:AD"))
End With
Note: This will not select down to last row (i.e. row 1,048,576), only to the last row with data in the specified range.

Excel VBA - how to check for non-blank values in hidden range

I'll start by making my objective clear, and then explaining it fully.
My goal is to check for non-blank values in a range, but only in the hidden cells of that range, and then use conditional formatting in a different cell, depending on whether the cells in the range are empty or not.
I have a named range called Location_Address_RangeCheck that covers the cells directly to the right of the location numbers, like this (location numbers are not part of the range).
When the Number of Locations is changed, the rows that go beyond that number (up to 25) are automatically hidden on worksheet_change to reduce clutter and reduce scrolling to see the stuff below it. That code works fine, so I'm not posting it here so as to not confuse anyone with what I'm trying to accomplish.
I want to provide a safeguard to ensure that there aren't values in the hidden rows that could affect outputs (i.e., if someone selects "3" for Number of Locations, but there is data in cells that might be on the row of the 8th location).
My goal is to check for non-blank values in the range, but only in the hidden cells, and then use conditional formatting in the cell next to the number of locations chosen, depending on whether the cells in the range are empty or not.
So if there is data in the hidden cells, then it would cause the sheet to look like this
.
I've tried so many different things so far, but I'm not making any progress. I've scoured the internet trying to find a solution, but everything I've found is about finding things in visible cells, which is the opposite of what I'm trying to achieve.
Here is the code I have written so far, which I know does not achieve my objective:
Sub testhiddencells()
Dim myRange As Range
Set myRange = Range("Location_Address_RangeCheck")
NumRows = Application.WorksheetFunction.CountA(myRange)
If Range("Location_Address_RangeCheck").Hidden = True Then
If Application.WorksheetFunction.CountA(Range("Location_Address‌​_RangeCheck")) <> 0 Then
MsgBox "There's something there"
End If
End If
End Sub
Here is a minimal example to check with a cell is both hidden and is non-empty:
Option Explicit
Sub Test()
Dim ws As Worksheet
Dim rngToCheck As Range
'test range - all cells populated with 'a' and 3 are hidden
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set rngToCheck = ws.Range("A1:A7")
If TestForNonBlankCellsInHiddenRange(rngToCheck) Then
'do you conditional format stuff here
End If
End Sub
Function TestForNonBlankCellsInHiddenRange(rngToCheck As Range) As Boolean
Dim rngCell As Range
Dim blnCheck As Boolean
'assume that hidden cells are blank
blnCheck = False
'iterate range
For Each rngCell In rngToCheck
If rngCell.EntireRow.Hidden And Not IsEmpty(rngCell.Value) Then
'found a hidden and non-empty cell
blnCheck = True
'debug address of this cell
Debug.Print rngCell.Address
End If
Next rngCell
'return check
TestForNonBlankCellsInHiddenRange = blnCheck
End Function
Looking at the code you used already, you should be able to adapt this to the particular use case of your worksheet.

Select discontinuous range based on column A

I have data in columns A:I. The data in column A will always go through to the last row, but other rows in other columns will sometimes be blank. How do I select the range based on the last row in column A? For example, sometimes column A will have 40 rows of data but column I will be blank after row 3. I would still want to select A1:I40.
Ultimately, I want to use VBA to format and put a filter on this range, so I am hoping to not include any blank rows after the last used row in column A.
Consider:
Sub qwerty()
Dim N As Long
N = Cells(Rows.Count, "A").End(xlUp).Row
Range("A1:I" & N).Select
End Sub
Gary's Student gave you the answer
maybe you're interested in expanding the feature and want to consider the last row with at least one non blank cell in the whole columns range (columns "A:I" in your example), irrespective of which column has it, than you could use:
Function LastRow(sht As Worksheet, columnsStrng As String) As Long
With sht
With Intersect(.UsedRange, .columns(columnsStrng)).SpecialCells(xlCellTypeConstants)
LastRow = .Areas(.Areas.Count).Row
End With
End With
End Function
and here follows an example of how to use it
Option Explicit
Sub main()
Dim ws As Worksheet
Set ws = Worksheets("mysheet1")
ws.columns("A:I").Resize(LastRow(ws, "A:I")).Select
End Sub
This assumes your data are constants (i.e. actual cells content is not a "formula").
But it can be easily enhanced to consider "formula" data as well

Visual Basic 2007 Adding values

To start with I'm not really a wise man. So I was trying to add up two values and display them in a third (that's easy) but I also wanted it to repeat an infinite amount of times (namely that it does the same for every row, let's say I place the result in I5, I want also, on every I under it (I6, I7, I8, etc...)
Should it be:
Private Sub Worksheet_Change()
if IsNumeric(Range("B1").sort) And IsNumeric(Range("B2").sort) then
Dim value1 As Single
Dim value2 As Single
range(I5).sort = value+1 + value2
End Sub
Or as I think I'm horribly mistaken?
You're using the .Sort property of Range where you should be using .Value.
There's a couple of ways to achieve what you're looking to do. First option is to iterate through the range and add the relevant value to each cell like so:
Public Sub addCells()
Dim rng As Range, cell As Range
'Set the sheet name
With ThisWorkbook.Worksheets("Sheet_Name")
'Set the range below:
Set rng = .Range("I1:I10")
'Loop through range and add cells together
For Each cell In rng
cell.Value = cell.Offset(0, 2) + cell.Offset(0, 1)
Next cell
End Sub
Another way to do it if the values to be added is ordered in for example column A and B would be:
Public Sub addCells()
Dim rng As Range, cell As Range
'Set the sheet name
With ThisWorkbook.Worksheets("Sheet1")
'Add the first formula to the sheet
.Range("C1").Value = "=SUM(A1+B1)"
'Change the range below to the range to be filled
.Range("C1").AutoFill Destination:=.Range("C1:C10")
End With
End Sub
