UserForm Controls — ScrollBar and SpinButton

UserForm acts as a container in which you add multiple ActiveX controls, each of which has a specific use and associated properties. By itself, a UserForm will not be of much use unless ActiveX controls are added to it which are the actual user-interactive objects. Using ActiveX Controls on a Worksheet have been illustrated in detail, in the separate section of «Excel VBA: ActiveX Controls, Form Controls & AutoShapes on a Worksheet».

Also refer «2. UserForm and Controls — Properties» for properties common to the UserForm and most Controls

Note: In below given examples, vba codes are required to be entered in the Code Module of the UserForm, unless specified otherwise.

ScrollBar Control

A ScrollBar control enables to change (increment or decrement) the value displayed by other UserForm controls (viz. TextBox, Label, …) or the value in a worksheet range. It scrolls through a range of values when a user: (i) clicks on the scroll arrows; (ii) drags the scroll box; or (iii) clicks in an area between a scroll arrow and the scroll box. ScrollBar & SpinButton controls — the difference between the two is that the ScrollBar box can be dragged to change the control’s value over larger increments (while keeping the increment low for clicks) which advantages a ScrollBar to make a selection from across a large number of values and cover an extremely wide range.

SmallChange Property specifies the incremental change, as an integer value (Long variable), that occurs when a user clicks the scroll arrow. The LargeChange Property specifies the incremental change when the user clicks between a scroll arrow and the scroll box. The default value is 1 for both the properties.

Min and Max Properties are integer values (Long variable) which specify the minimum and maximum acceptable values of the ScrollBar control (for the Value property setting). In a vertical ScrollBar clicking down the scroll arrow increases the value and the lowest position displays the maximum value (will be reverse when you click up the scroll arrow). In a horizontal ScrollBar clicking the right scroll arrow increases the value and the rightmost position displays the maximum value (will be reverse when you click the left scroll arrow).

Orientation Property determines a vertical ScrollBar or a horizontal ScrollBar. It has 3 settings: (i) fmOrientationAuto (Value -1) — this is the default value wherein the ScrollBar dimensions automatically determine whether the ScrollBar is Vertical or Horizontal. Where width is more than height, ScrollBar is Horizontal and where height is more than width, ScrollBar is Vertical; (ii) FmOrientationVertical (Value 0) — vertical ScrollBar; and (iii) FmOrientationHorizontal (Value 1) — horizontal ScrollBar.

Example 1: Creating a Mortgage Calculator, using ScrollBar controls. Refer Image 29. See vba codes below: 

Private Sub UserForm_Initialize()
‘Set properties of Controls on initialization of UserForm.

‘set properties for controls in re of Loan Amount:
TextBox1.BackColor = RGB(255, 255, 0)
TextBox1.TextAlign = fmTextAlignCenter
TextBox1.Font.Bold = True
TextBox1.Enabled = False

Label1.Caption = «Loan Amount ($):»
Label1.TextAlign = fmTextAlignLeft

ScrollBar1.Min = 0
ScrollBar1.Max = 10000
ScrollBar1.Orientation = fmOrientationHorizontal
ScrollBar1.SmallChange = 5
ScrollBar1.LargeChange = 100
ScrollBar1.Value = 0

‘set properties for controls in re of Annual Interest Rate:
TextBox2.BackColor = RGB(255, 255, 0)
TextBox2.TextAlign = fmTextAlignCenter
TextBox2.Font.Bold = True
TextBox2.Enabled = False

Label2.Caption = «Annual Int Rate (%):»
Label2.TextAlign = fmTextAlignLeft

ScrollBar2.Min = 0
ScrollBar2.Max = 1000
ScrollBar2.Orientation = fmOrientationHorizontal
ScrollBar2.SmallChange = 1
ScrollBar2.LargeChange = 10
ScrollBar2.Value = 0

‘set properties for controls in re of Loan Tenure:
TextBox3.BackColor = RGB(255, 255, 0)
TextBox3.TextAlign = fmTextAlignCenter
TextBox3.Font.Bold = True
TextBox3.Enabled = False

Label3.Caption = «Loan Tenure (Yrs)»
Label3.TextAlign = fmTextAlignLeft

ScrollBar3.Min = 0
ScrollBar3.Max = 50
ScrollBar3.Orientation = fmOrientationHorizontal
ScrollBar3.SmallChange = 1
ScrollBar3.LargeChange = 4
ScrollBar3.Value = 0

‘set properties for Label which displays Monthly Instalment:
Label4.Caption = «Monthly Instalment: $»
Label4.TextAlign = fmTextAlignCenter
Label4.BackColor = RGB(0, 255, 0)
Label4.Font.Bold = True

End Sub

Private Sub ScrollBar1_Change()

‘in re of Loan Amount, clicking the scroll arrow will increment amount by $5,000 and clicking between a scroll arrow and the scroll box will increment amount by $100,000:
TextBox1.Value = ScrollBar1.Value * 1000
TextBox1.Value = «$» & Format(TextBox1.Value, «#,##0»)

End Sub

Private Sub ScrollBar2_Change()

‘in re of Annual Interest Rate, clicking the scroll arrow will increment rate by 0.1% and clicking between a scroll arrow and the scroll box will increment rate by 1%:
TextBox2.Value = ScrollBar2.Value / 10

End Sub

Private Sub ScrollBar3_Change()

‘in re of Loan Tenure, clicking the scroll arrow will increment year by 0.5 and clicking between a scroll arrow and the scroll box will increment year by 2:
TextBox3.Value = ScrollBar3.Value / 2

End Sub

Private Sub CommandButton1_Click()
‘calculates the Monthly Instalment using the excel PMT function:

Dim mi As Currency

If Not TextBox1.Value > 0 Then

MsgBox «Please Enter Loan Amount!»

Exit Sub

ElseIf Not TextBox2.Value > 0 Then

MsgBox «Please Enter Annual Interest Rate!»

Exit Sub

ElseIf Not TextBox3.Value > 0 Then

MsgBox «Please Enter Loan Tenure!»

Exit Sub

Else

mi = Pmt((TextBox2.Value / 100) / 12, TextBox3.Value * 12, TextBox1.Value)

‘Label displays the monthly instalment, rounded off to 2 decimal points:

Label4.Caption = «Monthly Instalment: $» & Round(mi, 2) * -1

End If

End Sub

Private Sub CommandButton2_Click()
‘close button unloads the UserForm

Unload Me

End Sub

SpinButton Control

A SpinButton control, similar to a ScrollBar control, is used to increment or decrement the value (viz. a number, date, time, etc.) displayed by other UserForm controls (viz. TextBox, Label, …) or the value in a worksheet range. A SpinButton control (also referred to as a Spinner control) functions like a ScrollBar control, with similar properties (viz. SmallChange, Min, Max, Orientation, …). SmallChange Property specifies the incremental change, as an integer value (Long variable), that occurs when a user clicks the scroll arrow. A SpinButton control does not have a LargeChange property, like in a ScrollBar. In a vertical ScrollBar clicking up the scroll arrow decreases the value whereas clicking up the scroll arrow on a vertical Spinner increases the value.

ScrollBar & SpinButton controls — the difference between the two is that the ScrollBar box can be dragged to change the control’s value over larger increments (while keeping the increment low for clicks) which advantages a ScrollBar to make a selection from across a large number of values and cover an extremely wide range.

Example 2: Using a SpinButton control to change dates in TextBox, within a specified range:

Private Sub UserForm_Initialize()
‘populate a date in the TextBox

Dim dt As Date

‘disallow manual input in TextBox
TextBox1.Enabled = False

dt = «09/15/2011»
TextBox1.Text = dt

End Sub

Private Sub SpinButton1_SpinUp()
‘increase date by one day at a time, within the same month:

Dim dtUpper As Date

dtUpper = «09/30/2011»

If DateValue(TextBox1.Text) < dtUpper Then

TextBox1.Text = DateValue(TextBox1.Text) + 1

End If

End Sub

Private Sub SpinButton1_SpinDown()
‘decrease date by one day at a time, within the same month:

Dim dtLower As Date

If DateValue(TextBox1.Text) > dtLower Then

TextBox1.Text = DateValue(TextBox1.Text) — 1

End If

End Sub

Example 3: Move ListBox Items Up/Down in the list order and in the worksheet range, using the SpinButton control (by clicking Up or Down the scroll arrow). Refer Image 30. See below vba codes:

 Private Sub loadListBox()
‘load ListBox from worksheet range:

Dim n As Integer
Dim cell As Range
Dim rng As Range

    
Set rng = Sheet7.Range(«A1:A6»)

For n = 1 To ListBox1.ListCount

ListBox1.RemoveItem ListBox1.ListCount — 1

Next n

For Each cell In rng.Cells

Me.ListBox1.AddItem cell.Value

Next cell

End Sub

Private Sub UserForm_Initialize()
‘loads ListBox on initializing of UserForm

loadListBox

End Sub

Private Sub SpinButton1_SpinUp()
‘clicking up the scroll arrow moves the selected ListBox item one up both in the list order and also in the linked worksheet range:

Dim n As Long

n = ListBox1.ListIndex

If n > 0 Then

Sheet7.Range(«A» & n + 1).Value = Sheet7.Range(«A» & n).Value
Sheet7.Range(«A» & n).Value = ListBox1.Value

loadListBox

ListBox1.Selected(n — 1) = True

ElseIf ListBox1.ListIndex = 0 Then

MsgBox «First Item cannot be moved Up!»

Else

MsgBox «Please select item!»

End If

End Sub

Private Sub SpinButton1_SpinDown()
‘clicking down the scroll arrow moves the selected ListBox item one down both in the list order and also in the linked worksheet range:

Dim n As Long

n = ListBox1.ListIndex

If n >= 0 And n < ListBox1.ListCount — 1 Then

Sheet7.Range(«A» & n + 1).Value = Sheet7.Range(«A» & n + 2).Value
Sheet7.Range(«A» & n + 2).Value = ListBox1.Value

loadListBox

ListBox1.Selected(n + 1) = True

ElseIf ListBox1.ListIndex = ListBox1.ListCount — 1 Then

MsgBox «Last Item cannot be moved Down!»

Else

MsgBox «Please select item!»

End If

End Sub

Private Sub CommandButton1_Click()
‘clicking the Close button unloads the UserForm

Unload Me

End Sub

Some times we need to use very large userforms in our VBA projects. Size of the form depends on the number of fields and various objects we have in our form.  And if we need to show them in one window, we need to create big userform to put them all. You can create a form of any size by giving appropriate values for Height and width in properties window. But if our userform is bigger than the screen we need to use scroll bars inside our form. It is easier to put a scroll bar to a userform. But I saw that many people have problems with setting scroll bars correctly. Lot of people say that their scroll bars not working at run time. So there are few important things you should know when using scroll bars.

I will explain these important facts using a simple example. I have created a large form which has height of 1200 and width of 420. And there are a lot of text fields inside my userform.

If you look at properties window, you will notice that ScrollBars value is set to 0-fmScrollBarsNone by default. So we need to change this property depending on our requirement. If you have a userform with larger width, then you need to set ScrollBars value to 1-fmScrollBarsHorizontal. If you have a userform which has higher height, then you need to set this value to 2-fmScrollBarsVertical. And if you need scroll bars in both directions you can set the value to 3-fmScrollBarsBoth. You need to set to this value only if both width and height of your form is bigger than the screen.

You should set ScrollTop value to the 0. So then it will always appear at top.

Finally you need to set the ScrollHeight. It is very important to set appropriate value to this. Othewise you may not able to scroll up to the bottom of the form. Also if you set higher value, then user will scroll after the end of the objects. So user will see like your form is extended more than needed. So you should set a optimum value for this property for correct functionality and nice appearance. For example if you have a form having a height of 1200, you should set ScrollHeight value around 1850.
