[vba] How do I activate a specific workbook and a specific sheet?

How do I activate my Other workbook from the Current workbook? I have a current workbook with dumb.xls and The other workbook name as Tire.xls.I have opened the Tire.xls from the dumb.xls using worksbooks.open filename:= "name of the file".Its getting open but The problem is Im unable to make it work.

If I say cells(2,24).value=24 puts these value in the cell of dumb.xls but I want it to be done one Tire.xls.

activesheet.cells(2,24).value=24 puts these on Tire.xls. But how do i activate the Workbook with the name ? I need to open 3 to 4 excel workbooks And perform the operation? How do I activate the specific workbook

I have found this code on google

     activeworkbook.worksheet("sheetname").activate  ' but not working
     windows("sheetname").activate ' people on google suggested not to use

Its not getting activated. I dont know how to make it work. Can anyone tell me How do i activate a specific workbook and a specific sheet of the other workbook ?

Example: I have niko.xls and niko_2.xls opened as workbooks from the dumb.xls workbook so totally 3 workbooks and I have to activate the 2nd sheet of niko_2.xls workbook.How do I make it? Can anyone explain me the syntax with these example? Thank you in advance

The code that worked for me is:

ThisWorkbook.Sheets("sheetName").Activate

try this

Windows("name.xls").Activate

Dim Wb As Excel.Workbook
Set Wb = Workbooks.Open(file_path)
Wb.Sheets("Sheet1").Cells(2,24).Value = 24
Wb.Close

To know the sheets name to refer in Wb.Sheets("sheetname") you can use the following :

Dim sht as Worksheet    
For Each sht In tempWB.Sheets
    Debug.Print sht.Name
Next sht

You can try this.

Workbooks("Tire.xls").Activate

ThisWorkbook.Sheets("Sheet1").Select
Cells(2,24).value=24

You have to set a reference to the workbook you're opening. Then you can do anything you want with that workbook by using its reference.

Dim wkb As Workbook
Set wkb = Workbooks.Open("Tire.xls") ' open workbook and set reference!

wkb.Sheets("Sheet1").Activate
wkb.Sheets("Sheet1").Cells(2, 1).Value = 123

Could even set a reference to the sheet, which will make life easier later:

Dim wkb As Workbook
Dim sht As Worksheet

Set wkb = Workbooks.Open("Tire.xls")
Set sht = wkb.Sheets("Sheet2")

sht.Activate
sht.Cells(2, 1) = 123

Others have pointed out that .Activate may be superfluous in your case. You don't strictly need to activate a sheet before editing its cells. But, if that's what you want to do, it does no harm to activate -- except for a small hit to performance which should not be noticeable as long as you do it only once or a few times. However, if you activate many times e.g. in a loop, it will slow things down significantly, so activate should be avoided.
