Excel-VBA: Inputting range in userform call - vba

Question

I have growing data files and in a certain column is not fill out. I have the code to fill the data, though I want to make a button to call userform for user to fill in the range so that the code works within the range provided by the user(since data is adjusted by the user itself). The code to fill the blank cell is;
Sub fillblank()
Dim range As Range
Dim cell As Range
Dim value As String
Set range = Sheets("Sheet1").Range("E4:E15")
For Each cell In range
If Trim(cell.Value) <> "" Then
value = cell.Value
Else
cell.Value = value
End if
Next cell
End Sub
I would like the user to enter the range (E4:E15) in userform. How to do the userform if its dependent only range? Thanks stackoverflow.com.

Answer 1

Put a text box in userform and name it txtRng. Then declare a variable named MyRng as String. Assign that text box value to MyRng variable and use this variable as argument of range like...
Set range = Sheets("Sheet1").Range(MyRng)
So, full code will be like as below
Sub fillblank()
Dim range As range
Dim cell As range
Dim value As String
Dim MyRng As String
MyRng = UserForm1.txtRng 'Use your form name here
Set range = Sheets("Sheet1").range(MyRng)
For Each cell In range
If Trim(cell.value) <> "" Then
value = cell.value
Else
cell.value = value
End If
Next cell
End Sub
I also suggest you to not use range, value as variable because some of these reserve keyword. It may cause misbehave of output.

You could use the InputBox() method and have the user select a range:
Sub fillblank()
Dim myRange As Range
Dim cell As Range
Dim myValue As String
Set myRange = Application.InputBox( prompt:="Select a range", Type:=8)
For Each cell In myRange
If Trim(cell.Value) <> "" Then
myValue = cell.Value
Else
cell.Value = myValue
End if
Next
End Sub
or you could add a RefEdit control to your userform and process it
Sub fillblank()
Dim cell As range
Dim myValue As String
For Each cell In range(Me.RefEdit1.Text)
If Trim(cell.value) <> "" Then
myValue = cell.value
Else
cell.value = myValue
End If
Next cell
End Sub
In this case, since the user could input an invalid range, you may want to add a validation function (named GetRange in my following example)
Sub fillblank()
Dim myRange As range
If Not GetRange(Me.RefEdit1.Text, myRange) Then
MsgBox "Select a valid range "
Me.RefEdit1.SetFocus
Exit Sub
End If
Dim cell As range
Dim myValue As String
For Each cell In myRange
If Trim(cell.value) <> "" Then
myValue = cell.value
Else
cell.value = myValue
End If
Next cell
End Sub
Function GetRange(RefEditText As String, myRange As range) As Boolean
On Error Resume Next
Set myRange = range(RefEditText)
On Error GoTo 0
GetRange = Not myRange Is Nothing
End Function
finally, here is an alternative method (no loops) to fill blank cells as you're wanting to do:
Sub fillblank()
With range(Me.RefEdit1.Text).SpecialCells(xlCellTypeBlanks)
.FormulaR1C1 = "=R[-1]C"
.value = .value
End With
End Sub

To ask the user for a range you could use InputBox(Type:=8)
The code bellow will accept only one column
If an entire column is selected (A:A) or multiple columns it adjusts to the total rows in UsedRange and first column in selection
Option Explicit
Public Sub FillBlanks()
Dim selectedCol As Range, itm As Range, lr As Long
On Error Resume Next
Set selectedCol = Application.InputBox(Prompt:="Select column:", Type:=8)
On Error GoTo 0
If selectedCol Is Nothing Then Exit Sub 'User cancelled selection
With selectedCol
.Parent.Activate
lr = .Parent.UsedRange.Rows.Count
If .Columns.Count > 1 Then Set selectedCol = .Resize(.Rows.Count, 1)
If .Rows.Count < 2 Or .Rows.Count > lr Then Set selectedCol = .Resize(lr - .Row + 1, 1)
selectedCol.Select
End With
For Each itm In selectedCol
If Len(Trim$(itm)) = 0 And itm.Row > 1 Then itm.Value2 = itm.Offset(-1).Value2
Next
End Sub
Note: It's not recommended to name your variables with special VBA keywords
Dim range As Range - Range is the most important object in Excel
Dim value As String - Value is the most important property of the Range object
