Get User Selected Range - vba

How can I get a range of cells selected via user mouse input for further processing using VBA?

Selection is its own object within VBA. It functions much like a Range object.
Selection and Range do not share all the same properties and methods, though, so for ease of use it might make sense just to create a range and set it equal to the Selection, then you can deal with it programmatically like any other range.
Dim myRange as Range
Set myRange = Selection
For further reading, check out the MSDN article.

You can loop through the Selection object to see what was selected. Here is a code snippet from Microsoft (http://msdn.microsoft.com/en-us/library/aa203726(office.11).aspx):
Sub Count_Selection()
Dim cell As Object
Dim count As Integer
count = 0
For Each cell In Selection
count = count + 1
Next cell
MsgBox count & " item(s) selected"
End Sub

This depends on what you mean by "get the range of selection". If you mean getting the range address (like "A1:B1") then use the Address property of Selection object - as Michael stated Selection object is much like a Range object, so most properties and methods works on it.
Sub test()
Dim myString As String
myString = Selection.Address
End Sub

VBA Form - Vlookup cell and assign value to that cell

Encountering an issue in a VBA regarding vlookup function.
I have 2 comboboxes and 6 Textboxs for user input.
I want to use a vlookup (or index,Match(),Match()) to look up a cell in a data table and assign the values from the textboxes to these cells.
When I run the code for what I believe should work, it is returning object errors.
Private Sub CommandButton2_Click()
Dim MonthlyTable As Range
Set MonthlyTable = Sheets("DATA Monthly").Range("A6:AE400")
Dim ColumnRef As Range
Set ColumnRef = Sheets("Drivers").Range("N11")
' Assign CB2 value to M11 cell reference so it can be converted to a column ref in N11.
Sheets("Drivers").Range("M11").Value = ComboBox2.Value
Dim CB1Value As String
CB1Value = "Joiners" & ComboBox1.Value
Dim CB2Value As String
CB2Value = ComboBox2.Value
MsgBox CB1Value & " " & CB2Value
Dim tb1value As Range
tb1value = Application.WorksheetFunction.VLookup(CB1Value, MonthlyTable, ColumnRef, False)
tb1value.Value = TextBox1.Value
Unload Me
End Sub
I am at a loss for what to do here as I feel like it should be this simple!
Thanks in advance.
Edit. Further digging indicates that you cannot select a cell you are vlookup'ing as this commands only returns a value it does not actually select the cell for my intents and purposes.
not really clear to me you actual aim, but just following up your desire as stated by:
I want to use a vlookup (or index,Match(),Match()) to look up a cell
in a data table and assign the values from the textboxes to these
cells
you may want to adopt the following technique:
Dim tb1value As Variant '<--| a variant can be assigned the result of Application.Match method and store an error to be properly cheeked for
tb1value = Application.Match(CB1Value, MonthlyTable.Column(1), 0) '<--| try finding an exact match for 'CB1Value' in the first column of your data range
If Not IsError(tblvalue) Then MonthlyTable(tb1value, columnRef.Value).Value = TextBox1.Value '<--| if successful then write 'TextBox1' value in data range cell in the same row of the found match and with `columnRef` range value as its column index
Excel uses worksheet functions to manipulate data, VBA has different tools, and when you find yourself setting cell values on a sheet via VBA so that some worksheet function can refer to them it is time to look for a true VBA solution. I suggest the following which, by the way, you might consider running on the Change event of Cbx2 instead of a command button.
Private Sub Solution_Click()
' 24 Mar 2017
Dim MonthlyTable As Range
Dim Rng As Range
Dim Lookup As String
Dim Done As Boolean
Set MonthlyTable = Sheets("DATA Monthly").Range("A2:AE400")
' take the lookup value from Cbx1
Lookup = ComboBox1.Value
Set Rng = MonthlyTable.Find(Lookup)
If Rng Is Nothing Then
MsgBox Chr(34) & Lookup & """ wasn't found.", vbInformation, "Invalid search"
Else
With ComboBox2
If .ListIndex < 0 Then
MsgBox "Please select a data type.", vbExclamation, "Missing specification"
Else
TextBox1.Value = MonthlyTable.Cells(Rng.Row, .ListIndex + 1)
Done = True
End If
End With
End If
If Done Then Unload Me
End Sub
There are two points that need explanation. First, the form doesn't close after a rejected entry. You would have to add a Cancel button to avoid an unwanted loop where the user can't leave the form until he enters something correct. Note that Done is set to True only when the search criterion was found And a value was returned, and the form isn't closed until Done = True.
Second, observe the use of the ListIndex property of Cbx2. All the items in that Cbx's dropdown are numbered from 0 and up. The ListIndex property tells which item was selected. It is -1 when no selection was made. If you list the captions of your worksheet columns in the dropdown (you might do this automatically when you initialise the form) there will be a direct relationship between the caption selected by the user (such as "Joiners") and the ListIndex. The first column of MonthlyTable will have the ListIndex 0. So you can convert the ListIndex into a column of MonthlyTable by adding 1.
I think it is better to use "find" in excell vba to select a cell instead of using vlookup or other methods.

Assigning a combobox a named list in vba

I'm trying to dynamically assign a list to every combo box based on the values of a specific combo box. The idea is that the user picks a category from the specific combobox and all other combo boxes grab the items from that category in the form of a named list.
So the structure is like
Categories
Category 1
category 2
Category 1
Item 1
Item 2
And so on. I had this working on a fake set of names, but now that I'm using real named ranges, the code breaks. It is breaking on "For Each rng In ws.Range(str)" and stating that "method 'range' of object '_worksheet' failed.
This code works. Or worked. Then I changed ws to point to a different sheet of named ranges and now nothing works.
The value of CBOCategory is any value from a list of all named ranges, but it seems like Excel isn't seeing any of them! I tried to trigger even a listfill assignment instead of adding each item and got a similar error
Private Sub CBOCategory_Change()
'Populate dependent combo box with appropriate list items
'according to selection in cboCategoryList.
Dim rng As Range
Dim ws As Worksheet
Dim str, temp, cbName As String
Dim counter As Integer
Set ws = Worksheets("Item Master")
Dim obj As OLEObject
str = CBOCategory.Value
For Each obj In ActiveSheet.OLEObjects
If obj.Name = "CBOCategory" Then
' nothing
Else
temp = obj.Object.Value
obj.Object.Value = ""
For Each rng In ws.Range(str)
obj.Object.AddItem rng.Value
Next rng
obj.Object.Value = temp
End If
'MsgBox ("updated!")
Next obj
End Sub
The code works fine. The root cause of the issue is that the named ranges were being dynamically set by a formula. The formulas were not calculating properly when the code ran, so vba could not use a dynamically set named range to find another, also dynamically set named range.
The solution is to explicitly set the named ranges. Then the code works fine.

Searching and Returning bold values in VBA

I know that this probably isn't the most ideal way to to do this but just bear with me.
I have a document with a few tables on it. I'm using a userform to search the tables/sub-categories and return the relevant values. I want to select the sub categories with a range of option buttons on a userform, these will in turn set the range for the search function to look within. I also want to dynamically update the option buttons if a new table was to be added or anything along those lines.
The only thing that differentiates the title of a sub-category/table, and the items within it, is that the title of a sub-category/table is bold. So what I'm looking to do is search the first column of the spreadsheet and return the names of any entries in bold. These values are then used to set the names of the option buttons :).
The following function is my attempt at finding the text entities in column a that are in bold, returning them and setting each to an individual variable to be used in another function. The bold1 .... variables are all globally defined variables as I need them in another sub, as is the page variable which contains the relevant page to be used. Currently the code returns an error stating "variable or with block not set" and using the debugger I can see that bold1 .... and all the other boldx variables have no value set. Does anybody know whats going on/how to fix this function.
Thanks in advance :)
Sub SelectBold()
Dim Bcell As Range
For Each Bcell In Worksheets(Page).Range("A1:A500")
If Bcell.Font.Bold = True Then
Set bold1 = Bcell
End If
Next
End Sub
EDIT: I simplified the above function, to remove clutter and help narrow in on the issue. I want the above function to store the contents of the found cell (any cell in the document in bold at this stage) in the variable bold1
This will return an array of values from bold cells in column A of Page.
You can fill a combo or list box with theses values using their list property.
ComboBox1.List = getSubCategories("Sheet1")
Function getSubCategories(Page As String) As String()
Dim arrSubCategories() As String
Dim count As Long
Dim c As Range
With Worksheets(Page)
For Each c In .Range("A2", .Range("A" & Rows.count).End(xlUp))
If c.Font.Bold Then
ReDim Preserve arrSubCategories(count)
arrSubCategories(count) = c.Value
count = count + 1
End If
Next
End With
getSubCategories = arrSubCategories
End Function
you may find useful to have a Range returned with subcategories cells found:
Function SelectBold(Page As String, colIndex As String) As Range
With Worksheets(Page)
With .Range(colIndex & "1", .Cells(.Rows.Count, colIndex).End(xlUp)).Offset(, .UsedRange.Columns.Count)
.FormulaR1C1 = "=if(isbold(RC[-1]),"""",1)"
.Value = .Value
If WorksheetFunction.CountA(.Cells) < .Rows.Count Then Set SelectBold = Intersect(.SpecialCells(xlCellTypeBlanks).EntireRow, .Parent.Columns(1))
.Clear
End With
End With
End Function
Function IsBold(rCell As Range)
IsBold = rCell.Font.Bold
End Function
to be possibly exploited as follows:
Option Explicit
Sub main()
Dim subCategoriesRng As Range, cell As Range
Set subCategoriesRng = SelectBold(Worksheets("bolds").Name, "A") '<--| pass worksheet name and column to search in
If Not subCategoriesRng Is Nothing Then
For Each cell In subCategoriesRng '<--| loop through subcategories cells
'... code
Next cell
End If
End Sub

List Box shows dates that aren't in the range

I'm having trouble with my Listbox. When I run the following code for the first time, it always runs showing only 1 date which is 30/12/1899. The range that I've specified only contains 6 dates which are 8/1/2014, 9/1/2014, 14/1/2014, 24/1/2014, 24/1/2014 and 02/02/2014.
Once I stop the form and run it again, all the required dates show up.
I've just started learning VBA on Excel so I'm still struggling to understand the concepts.
Is there something that I'm missing? The reason for no duplicates is that I can't show the 2 dates (24/01/2014).
Private Sub UserForm_Activate()
Dim AllCells As Range, Cell As Range
Dim NoDupes As New Collection
Dim i As Integer, j As Integer
Dim Swap1, Swap2, Item
Dim wksJobDetail As Worksheet
'The items are in A2:A7
Set AllCells = Range("A2:A7")
'Point the variable to JobSchedule worksheet
Set wksJobDetail = Application.Workbooks("xxxxx.xlsm").Worksheets("JobSchedule")
wksJobDetail.Activate
'Statement ignores any errors regarding duplicates and duplicate dates aren't added
On Error Resume Next
For Each Cell In AllCells
NoDupes.Add Format(CDate(Cell.Value), "dd/mm/yyyy"), _
CStr(Format(CDate(Cell.Value), "dd/mm/yyyy"))
Next Cell
'Add non-duplicated items into lstDate
For Each Item In NoDupes
JobDetail.lstDate.AddItem Item
Next Item
End Sub
Set AllCells = Range("A2:A7") will reference the active worksheet which may or may not be wksJobDetail.
The second time you run it wksJobDetail has been activated.
Try putting the Set AllCells = Range("A2:A7") statement after:
Set wksJobDetail = Application.Workbooks("xxxxx.xlsm").Worksheets("JobSchedule")
wksJobDetail.Activate
I think it has something to do with how you format your data in Excel and the proper way of referencing source range.
Try this:
First, check if the dates are correctly entered as dates in Excel like below.
Then make this line explicit:
Set AllCells = Range("A2:A7")
and change to this:
Set AllCells = Sheets("JobSchedule").Range("A2:A7")
Now, run your code which I've rewritten below adding On Error Goto 0.
Dim AllCells As Range, Cell As Range, Item
Dim NoDupes As New Collection
Set AllCells = Sheets("JobSchedule").Range("A2:A7")
On Error Resume Next '~~> Ignore Error starting here
For Each Cell In AllCells
NoDupes.Add Format(CDate(Cell.Value), "dd/mm/yyyy"), _
CStr(Format(CDate(Cell.Value), "dd/mm/yyyy"))
Next Cell
On Error GoTo 0 '~~> Stops ignoring error
For Each Item In NoDupes
JobDetail.lstDate.AddItem Item
Next Item
And that should give you the result you want. Also, I suggest to use Initialize Event instead of Activate.
Everytime you use OERN, do not forget to use OEG0 to reset the error handling.
Otherwise, you will not be able to trap other errors not related to the adding existing item in Collection.
Bonus:
Another way to do this is to use a Dictionary instead. You need to add reference to Microsoft Scripting Runtime. I rewrote part of your code which will have the same effect. The advantage of a Dictionary is that it offers other helpful properties that you can use.
Private Sub UserForm_Initialize()
Dim AllCells As Range, Cell As Range
Dim d As Dictionary
Set AllCells = Sheets("Sheet1").Range("A2:A7")
Set d = New Dictionary
For Each Cell In AllCells
d.Item(Format(CDate(Cell.Value), "dd/mm/yyyy")) = _
CStr(Format(CDate(Cell.Value), "dd/mm/yyyy"))
Next Cell
JobDetail.lstDate.List = d.Keys
End Sub
As you can see, we removed one Loop by using Keys property which is an array of all unique keys. I hope this somehow helps.

Can I use VBA function to return a (dynamic) list of acceptable values into Excel's data validation?

For a given cell, I select Data/Validation and set Allow to "List". I now wish to set Source like so:
=rNames(REGS)
but that does not work (name not found). So I go Insert/Name/Define and create "REGNAMES" by simply assigning the formula above (no cell range). I then return to the Data/Validation and when I set Source like so:
=REGNAMES
Now I get "Source currently evaluates to error". Unfortunately, this error does not go away even after I ignore it. I can create a range formula in the sheet like so:
{=REGNAMES}
and drag this to the right across a couple cells and the rNames function faithfully returns
Option #1 | Options #2 | ...
That is, the function returns a range as intended.
I know that I can use macro code to manipulate the List setting for that cell out of VBA. I don't like these side-effects much. I would prefer a clean dependency tree built on functions. Any ideas how to get the Data/Validation to accept the array values returned from rNames?
Thanks.
PS: rNames returns the result range as a Variant, if that has any bearing.
I think the problem is that data validation dialog only accepts the following "lists":
an actual list of things entered directly into the Source field
a literal range reference (like $Q$42:$Q$50)
a named formula that itself resolves to a range reference
That last one is key - there is no way to have a VBA function just return an array that can be used for validation, even if you call it from a named formula.
You can write a VBA function that returns a range reference, though, and call that from a named formula. This can be useful as part of the following technique that approximates the ability to do what you actually want.
First, have an actual range somewhere that calls your arbitrary-array-returning VBA UDF. Say you had this function:
Public Function validationList(someArg, someOtherArg)
'Pretend this got calculated somehow based on the above args...
validationList = Array("a", "b", "c")
End Function
And you called it from $Q$42:$Q$50 as an array formula. You'd get three cells with "a", "b", and "c" in them, and the rest of the cells would have #N/A errors because the returned array was smaller than the range that called the UDF. So far so good.
Now, have another VBA UDF that returns just the "occupied" part of a range, ignoring the #N/A error cells:
Public Function extractSeq(rng As Range)
'On Error GoTo EH stuff omitted...
'Also omitting validation - is range only one row or column, etc.
Dim posLast As Long
For posLast = rng.Count To 1 Step -1
If Not IsError(rng(posLast)) Then
Exit For
End If
If rng(posLast) <> CVErr(xlErrNA) Then
Exit For
End If
Next posLast
If posLast < 1 Then
extractSeq = CVErr(xlErrRef)
Else
Set extractSeq = Range(rng(1), rng(posLast))
End If
End Function
You can then call this from a named formula like so:
=extractSeq($Q$42:$Q$50)
and the named formula will return a range reference that Excel will accept an allowable validation list. Clunky, but side-effect free!
Note the use of the keyword 'Set' in the above code. It's not clear from your question, but this might be the only part of this whole answer that matters to you. If you don't use 'Set' when trying to return a range reference, VBA will instead return the value of the range, which can't be used as a validation list.
I was just doing some research on accessing the contents of a Shapes dropdown control, and discovered another approach to solving this problem that you might find helpful.
Any range that can have a validation rule applied can have that rule applied programmatically. Thus, if you want to apply a rule to cell A1, you can do this:
ActiveSheet.Range("A1").Validation.Add xlValidateList, , , "use, this, list"
The above adds an in-cell dropdown validation that contains the items "use," "this," and "list." If you override the Worksheet_SelectionChange() event, and check for specific ranges within it, you can call any number of routines to create/delete validation rules. The beauty of this method is that the list referred to can be any list that can be created in VBA. I needed a dynamically-generated list of an ever-changing subset of the worksheets in a workbook, which I then concatenated together to create the validation list.
In the Worksheet_SelectionChange() event, I check for the range and then if it matches, fire the validation rule sub, thus:
Private Sub Worksheet_SelectionChange(ByVal Target as Range)
If Target.Address = "$A$1" Then
UpdateValidation
End If
End Sub
The validation list-builder code in UpdateValidation() does this:
Public Sub UpdateValidation()
Dim sList as String
Dim oSheet as Worksheet
For Each oSheet in Worksheets
sList = sList & oSheet.Name & ","
Next
sList = left(sList, len(sList) -1) ' Trim off the trailing comma
ActiveSheet.Range("A1").Validation.Delete
ActiveSheet.Range("A1").Validation.Add xlValidateList, , , sList
End Sub
And now, when the user clicks the dropdown arrow, he/she will be presented with the updated validation list.
Sounds like your rNames function is probably returning a 1-dimensional array (which will be treated as a row).
Try making your function return a column as a 1-based 2-dimensional array (Ansa(1,1) then Ansa(2,1) etc)
Couln't you rather use dynamic range names ? That's quite easy and does not require any vba.
For the future:
Following is then used in a named range and the named range set as the 'Data Validation' 'List' value
Function uniqueList(R_NonUnique As Range) As Variant
Dim R_TempList As Range
Dim V_Iterator As Variant
Dim C_UniqueItems As New Collection
On Error Resume Next
For Each V_Iterator In R_NonUnique
C_UniqueItems.Add "'" & V_Iterator.Parent.Name & "'!" & V_Iterator.Address, CStr(V_Iterator.Value2)
Next V_Iterator
On Error GoTo 0
For Each V_Iterator In C_UniqueItems
If R_TempList Is Nothing Then
Set R_TempList = Range(V_Iterator)
End If
Set R_TempList = Union(R_TempList, Range(V_Iterator))
Next V_Iterator
Set uniqueList = R_TempList
End Function
#user5149293 I higly appreciate your code, but I recommend to prevent the collection from throwing an error, when adding duplicate values. The usage of a custom formula in the data validation list or in Name-Manager-Formula prevents the code from using the vbe debugger, which makes it very hard to trace back errors here (I ran into this problem myself, when using your code).
I recommend to check the existence of key in the collection with a separate function:
Function uniqueList(R_NonUnique As Range) As Variant
'Returns unique list as Array
Dim R_TempList As Range
Dim V_Iterator As Variant
Dim C_UniqueItems As New Collection
For Each V_Iterator In R_NonUnique
'Check if key already exists in the Collection
If Not HasKey(C_UniqueItems, V_Iterator.Value2) Then
C_UniqueItems.Add Item:="'" & V_Iterator.Parent.Name & "'!" & V_Iterator.Address, Key:=CStr(V_Iterator.Value2)
End If
Next V_Iterator
For Each V_Iterator In C_UniqueItems
If R_TempList Is Nothing Then
Set R_TempList = Range(V_Iterator)
End If
Set R_TempList = Union(R_TempList, Range(V_Iterator))
Next V_Iterator
Set uniqueList = R_TempList
End Function
