Declaring an active workbook variable Excel Vba

Question

(Excel VBA)

How would i declare an active workbook variable. or a workbook variable in general.

I have a program flipping back and forth between 2 excel workbooks, and currently we have it just reopen that workbook. But can I just declare it as a variable so i can reference it without re-opening. It would make my life a lot easier .

Thanks in advance!

My current example:

Dim xlsMatrixUp As String
fileToOpen = Application.GetOpenFilename("Excel Files (*.xls), *.xls")
xlsMatrixUp = fileToOpen
Workbooks.Open xlsMatrixUp
ActiveWorkbook.Worksheets(4).Activate 'Grabs matrix file

'Goes back to sheet with macro
ThisWorkbook.Worksheets(4).Activate
    ActiveSheet.range("A1").Interior.Color = RGB(128, 128, 128)
'This is off a working if statement 
Workbooks.Open xlsMatrixUp
ActiveWorkbook.Worksheets(4).Activate`
'Returns to matrix and repeats. Any suggestions?

Solution

Dim wB as Workbook
Set wB = Workbooks.Open(xlsMatrixUp)

then you can refer to it as wB.worksheets(4).Activate for example

You sir, deserve a pat on the back

You're very welcome. Obviously, you can also declare a worksheet and refer to it right away. Set wS = wB.Worksheets(4) and then refer to it directly as wS.Range("A1")
