How to check for data in TextBox - vba

Question

I have a worksheet named "Input" with a Button (ActiveX) and a TextBox (ActiveX). I used VBA to check value of the TextBox when a user clicks the button, but the code cant find the textbox.
My code for the button:
Sub Toevoegen()
Dim invoerenws As Worksheet
Dim overzichtws As Worksheet
Dim nextRow As Long
Dim oCol As Long
Dim myRng As Range
Dim myCopy As String
Dim myCell As Range
'cells to copy from Input sheet - some contain formulas
myCopy = "TextBox1"
Set invoerenws = Worksheets("invoeren")
Set overzichtws = Worksheets("overzicht")
With overzichtws
nextRow = .Cells(.Rows.Count, "A").End(xlUp).Offset(1, 0).Row
End With
With invoerenws
Set myRng = .Range(myCopy)
If Application.CountA(myRng) <> myRng.Cells.Count Then
MsgBox "Please fill in all the cells!"
Exit Sub
End If
End With
With overzichtws
With .Cells(nextRow, "A")
.Value = Now
.NumberFormat = "mm/dd/yyyy hh:mm:ss"
End With
.Cells(nextRow, "B").Value = Application.UserName
oCol = 3
For Each myCell In myRng.Cells
overzichtws.Cells(nextRow, oCol).Value = myCell.Value
oCol = oCol + 1
Next myCell
End With
'clear input cells that contain constants
With invoerenws
On Error Resume Next
With .Range(myCopy).Cells.SpecialCells(xlCellTypeConstants)
.ClearContents
Application.GoTo .Cells(1) ', Scroll:=True
End With
On Error GoTo 0
End With
End Sub

If the values are still inside the textBox then you have to reference the object or the control. you can do it like this:
textBox.value = worksheet.cells(1,1)
What this will do is display the value of textBox form control to cell A1. I know this is not what you are looking for but this is the simplest way of showing you how to reference userform objects or controls. You can find the name of a textBox control on a window like this:
You need to use the (Name) when referencing textboxes
