VBA Code - Filter using Array

matbla91 — Mon, 09 May 2022 12:51:00 GMT

Hi,

i need to filter data in Excel spreadsheet. It can be dynamic number of values (or). In the vba code it should look like below:

Worksheets("Sheet1").ListObjects("Table1").Range.AutoFilter _ Field:=1, _ Criteria1:=Array("1", "3", "Seattle", "Redmond"), _ Operator:=xlFilterValues

but in the Blue Prism Code Stage it is not accepted

ws.usedRange.AutoFilter(field:=ColumnNumber, Criteria1:=Array(Criteria1), Operator:=7)

How can I filter using array in the Blue Prism?

Page: FilterData Array
Stage: FilterData Array
Type: Error
Action: Validate
Description: Compiler error at line 8: 'Array' is a class type and cannot be used as an expression.
Repairable: No

Best,
Mateusz

Hi Mateusz,

You can create a new action called 'Filter Values' by extending the 'MS Excel' VBO object which consists of other actions. Add the following input parameters to this action:

- Handle (Number) : The instance of the excel sessions held in the dictionary to establish the current excel connection.

- Workbook Name (Text) : The workbook name returned while using either 'Open Workbook' or 'Create Workbook' actions.

- Worksheet Name (Text) : The worksheet name where the operation needs to be performed.

- Table Name (Text) : The name of the table where the action needs to be performed.

- Field Index (Text) : The index of the column where filter needs to be applied starting from the position 1 to N.

- Array Values (Collection) : The collection with a single column named 'Field Values' comprising of all the filter values for the selected field index column

Prerequisite:

Add the following Namespace Import and External Reference in the Page Descriptions stage of the Initialize page:

Also, ensure that the following DLL is installed inside your Blue Prism installation folder. I have provided the same in the attached zip file:

Solution Workflow:

Now add a code stage called 'Filter Values' with the following parameters and code:

Dim wb, ws As Object
Dim excel, sheet As Object
Dim StrList As New List(Of String)

wb = GetWorkbook(Handle, Workbook_Name)
ws = GetWorksheet(Handle, Workbook_Name, Worksheet_Name)

wb.Activate()
ws.Activate()

excel = ws.Application
sheet = excel.ActiveSheet

For Each row As DataRow In Array_Values.Rows

If row("Field Values") IsNot Nothing Then
StrList.Add(row("Field Values").ToString)
End If

Next

sheet.ListObjects(Table_Name).Range.AutoFilter(Field:=Field_Index, Criteria1:=StrList.ToArray(),Operator:=Microsoft.Office.Interop.Excel.XlAutoFilterOperator.xlFilterValues)

Test Scenario:

I have the following excel file where I will be filtering the table based on few of the product names:

I will be passing the field index as '2' since I want to apply filter on second column along with the following array values collection:

Upon running the workflow, I get the following output:
