  Function That Returns An Object

  Sep 09, 2016 01:15 AM|sg48asp|LINK

  I am writing a function that I want to return a two dimension variant array. However Visual Studio is changing the function declaration to object

  Public Function CellExtractionArray(ByRef OrigFormula As String) As Object(,)
  
          Dim vCellArray(,) As Object
  
                  'irrelevant code deleted
  
  
                  ReDim Preserve vCellArray(3, ValidCellCount)
                  vCellArray(0, 0) = ValidCellCount
                  vCellArray(1, ValidCellCount) = Mid(OrigFormula, PossibleStartPosition, PossibleEndingPosition -             PossibleStartPosition + 1)
                  vCellArray(2, ValidCellCount) = PossibleStartPosition
                  vCellArray(3, ValidCellCount) = PossibleEndingPosition
              End If
              ValidCell = False
          Next 'Candidate
          CellExtractionArray = vCellArray
  Return CellExtractionArray
  
  
      End Function

  I had coded the function as a variant and vCellArray as a variant but they were changed by VS to objects.

  Question 1: I am getting an intellisense error saying that near the end of above code saying that vCellArray is being used before it ha been assigned a value. How do I prevent this? How should I initialize vCellArray?

  In the procedure that calls this function, my variant declarations were changed to objects. see below. How do I convert the object returned by my function to a variant array? Do I have to use CType?

  Public Function PredictedFormula(ByVal OrigFormula As String) As String
  
          Dim CellExtractedArray(,) As Object
          Dim FormulaPieces(), NewFormula As String
          CellExtractedArray = CellExtractionArray(OrigFormula)
        
          Try
              For j = 1 To CInt(CellExtractedArray(0, 0)) 'Number of Cells in the formula
                  'Get Cells and Position in the formula
                  CellString = CStr(CellExtractedArray(1, j))
                  StartPos = CInt(CellExtractedArray(2, j))
                  EndPos = CInt(CellExtractedArray(3, j))

  Hi sg48asp,

  Question 1: I am getting an intellisense error saying that near the end of above code saying that vCellArray is being used before it ha been assigned a value. How do I prevent this? How should I initialize vCellArray?

  You can change your code as the below.

  Dim obj1 As Object
  Set obj1 = New Project1.YourClass

  You can use CType.

          Dim anArray As Array
          anArray = CType(declarations, Array)
