How to make counting the cells with button in Excel, VBA? - excel

Question

I'm making the simple app using the VBA code and forms in Excel. So, I need to have a simple Private Sub CommandButton1_Click() method which will call for calculation methods and write down the results in Label. How can I do this? (yes, I'm new to VBA)
Private Sub CommandButton1_Click()
MsgBox "My text here"
End Sub
Private Sub UserForm_DblClick(ByVal Cancel As MSForms.ReturnBoolean)
CommandButton1_Click
End Sub
But instead of the calling the window with my text there I need to make calculations of cells.
Will it be correct if I'll write code like shown down there and somehow add the calculations of cells?
Sub Button1_Click()
Sheet1.testing
End Sub
Sub testing()
Dim ell As Object
Dim post As String
Dim Count As Double
Dim cm As String
End Sub

Answer 1

In vba editor, double-click on the command-button in the UserForm to enter the code:
If you put the sub-procedure in the module (e.g doSomething sub-procedure), you have to add the module name:
Call Module1.doSomething
Option Explicit
Private Sub CommandButton1_Click()
Call doSomething
End Sub
'--------------------------------------
Sub doSomething()
MsgBox "My text here"
End Sub

#FunThomas helped me (you can see it in comments to this question). And here is the solution on my question:
Private Sub CommandButton1_Click()
testing
End Sub
Sub testing()
Dim value1
calc = value1 + 10
Label1 = value1 + 10
Dim ell As Object
Dim post As String
Dim Count As Double
Dim cm As String
Dim sText As String
sText = Sheet1.Range("A1").Value
Label2 = sText
End Sub
