Excel VBA - Dictionary - storing and retrieving values

Krishna picture Krishna · Nov 14, 2013 · Viewed 23.7k times · Source

I am working on below table and with help of Excel VBA - Dictionary - I am trying to capture all the details - 1) First step is to search in "Results Out" Column - if the value is "No" - then we need to read all the values with their appropriate header. 2) So for 2nd record - i.e., Name = XYZ - we need to store all the details. Based on No. of Subjects column - we need to store value of all the subjects and their corresponding marks - will be used for further calculation and generate the "Result" column.

I got it partially working - like I am able to capture details - but not able to store details of all the subject and their marks:

Sr. No. Results Out?    Result  Name    Age No. of Subjects Subject Names   Marks
1           Yes          Pass   ABC      21       3          Maths           10
                                                             Science         26
                                                             History         34
2           No                  XYZ      10       2          Maths           24
                                                             Science         36

Below is the code that I have used that is partially working:

Public Sub test_dict()

Dim dict As New Scripting.dictionary
Set dict = New dictionary

sSheetIndex = 1
intTargetRow = 2

Set objUsedRange = Worksheets.Item(3).UsedRange

For Iter = 1 To objUsedRange.Columns.Count
   sCellName = objUsedRange.Cells(1, Iter)
   sCellValue = objUsedRange.Cells(intTargetRow, Iter)
   dict.Item(sCellName) = sCellValue

Next


For i = 0 To dict.Count - 1
    s = dict.Items()(i)
    Debug.Print dict.Keys()(i) & " " & dict.Items()(i)
    Debug.Print s
Next i

End Sub

Resolved the issue with below code - had to use 2 seperate dictionaries:

Public Sub test_dict()

Dim dict As New Scripting.dictionary
Set dict = New dictionary

sSheetIndex = 1
intTargetRow = 2

Set objUsedRange = Worksheets.Item(3).UsedRange

For Iter = 1 To objUsedRange.Columns.Count
   sCellName = objUsedRange.Cells(1, Iter)
   sCellValue = objUsedRange.Cells(intTargetRow, Iter)
   dict.Item(sCellName) = sCellValue

    If sCellName = "Subject Names" Then
        Call test_dict_2
    End If

Next

For i = 0 To dict.Count - 1
    s = dict.Items()(i)
    Debug.Print dict.Keys()(i) & " " & dict.Items()(i)
    Debug.Print s
Next i

End Sub



Public Sub test_dict_2()

Dim dict_2 As New Scripting.dictionary
Set dict_2 = New dictionary

sSheetIndex = 1
intTargetRow = row_counter

Set objUsedRange = Worksheets.Item(3).UsedRange

For Iter = 1 To objUsedRange.Columns.Count
   sHeader = objUsedRange.Cells(1, Iter)
   sCellValue = objUsedRange.Cells(intTargetRow, Iter)

    If sHeader = "No. of Subjects" Then
        mv_cnt = sCellValue
    End If

    If sHeader = "Subject Names" Then

        Dim a
        a = Iter + mv_cnt
        For Iter_2 = Iter To (a - 1)

            sHeader = objUsedRange.Cells(1, Iter)
            sCellName = objUsedRange.Cells(intTargetRow, Iter)
            sCellValue = objUsedRange.Cells(intTargetRow, Iter + 1)
            dict_2.Item(sCellName) = sCellValue
            intTargetRow = intTargetRow + 1

        Next

        intTargetRow = row_counter

    End If

Next

For i = 0 To dict_2.Count - 1
    s = dict_2.Items()(i)
    Debug.Print dict_2.Keys()(i) & " " & dict_2.Items()(i)
    Debug.Print s
Next i

Set dict_2 = Nothing

End Sub
