Date disappearing after > checking in loop

[bradmsg]

Hi all. Trying to figure out why this date disappears. Trying to get the instance with the oldest date. Sheet 2 has a column (16) with dates. Column 6 has my column that im checking for duplicates if its a duplicate, i want it to grab the oldest date.

not sure why this date is disappearing. any ideas?

[CODE=vba]Sub Find()
Dim dict As New Dictionary
    
    Dim rg As Range
    Set rg = Sheet2.Range("A3").CurrentRegion
    
    Dim i As Long, RPUID As Long, InspectionDate As String
    Dim MDI As Long, BLDG As Class_BLDG
    
    For i = 4 To rg.Rows.Count
        RPUID = rg.Cells(i, 6).Value
        MDI = rg.Cells(i, 7).Value
        InspectionDate = CDate(rg.Cells(i, 16).Value)
        
        'Debug.Print InspectionDate
        
        If dict.Exists(RPUID) = True Then ' if exists then
            Set BLDG = dict(RPUID) 'get existing item at the key
        Else
            Set BLDG = New Class_BLDG 'initiates this instance for items not already in dictionary
            dict.Add RPUID, BLDG ' adds RPUID (Key) to THIS BLDG.
            
        End If
        'Debug.Print InspectionDate
        
        If BLDG.InspectionDate > InspectionDate Then
            InspectionDate = BLDG.InspectionDate
        End If
        Debug.Print BLDG.InspectionDate


         'BLDG.MDI = BLDG.MDI + MDI
        'BLDG.InspectionDate = InspectionDate ' Adds inspection date to THIS RPUID(Key)
        BLDG.MDI = MDI ' Adds MDI to THIS RPUID(Key)
        
        
    Next i
    
End Sub

Not sure what had happenned. But, try to use .value2, instead of .value for cells those are date
for ex:
RPUID = rg.Cells(i, 6).Value
become
RPUID = rg.Cells(i, 6).Value2

 

[Alex Blakenburg]

I agree with bebo on the value2 but shouldn't there be a line that looks like the below in the code somewhere ?
Where are you putting the date "into" the class object ?

BLDG.InspectionDate= InspectionDate

 

[bradmsg]

The way I understand, BLDG.InspectionDate > InspectionDate is checking the current data in BLDG.InspectionDate to the current iteration InspectionDate.

Ahh should I put BLDG.InspectionDate= InspectionDate Under If dict.Exists(RPUID) = True Then to make sure the first iteration has that data?

I don't have a copy of your class module or any sample data from you (XL2BB) so I haven't tested this but see if these changes help.
Note: Test if BLDG.InspectionDate = "" works when you haven't added anything into BLDG.InspectionDate in case you need to test for IsEmpty or = 0 instead.

I suspect you may already have seen this but Paul Kelly's video covers a very similar example (14.5 mins)

Sub FindEarliestDate()
    Dim dict As New Dictionary
 
    Dim rg As Range
    Set rg = Sheet2.Range("A3").CurrentRegion
 
    Dim i As Long, RPUID As Long, InspectionDate As String
    Dim MDI As Long, BLDG As Class_BLDG
 
    For i = 4 To rg.Rows.Count
        RPUID = rg.Cells(i, 6).Value
        MDI = rg.Cells(i, 7).Value
        InspectionDate = CDate(rg.Cells(i, 16).Value2)      ' XXX Changed to Value2
     
        'Debug.Print InspectionDate
     
        If dict.Exists(RPUID) = True Then ' if exists then
            Set BLDG = dict(RPUID) 'get existing item at the key
        Else
            Set BLDG = New Class_BLDG 'initiates this instance for items not already in dictionary
            dict.Add RPUID, BLDG ' adds RPUID (Key) to THIS BLDG.
        End If
        'Debug.Print InspectionDate
     
        ' XXX Changed --> store InspectionDate if Lower but not if empty
        If BLDG.InspectionDate = "" Or (BLDG.InspectionDate > InspectionDate And InspectionDate <> 0) Then
            BLDG.InspectionDate = InspectionDate
        End If
     
        Debug.Print BLDG.InspectionDate

         'BLDG.MDI = BLDG.MDI + MDI
        'BLDG.InspectionDate = InspectionDate ' Adds inspection date to THIS RPUID(Key)
        BLDG.MDI = MDI ' Adds MDI to THIS RPUID(Key)
            
    Next i
 
End Sub

Solid logic! Once I am back with my data, I’ll give it a go. Thank you!!!! That also gives me some more examples for checking some other cells as a next step!

Yes, I think I watched it this morning!

 

[bradmsg]

Alex,

Your code worked! Thanks for your input!

Ahh should I put BLDG.InspectionDate= InspectionDate Under If dict.Exists(RPUID) = True Then to make sure the first iteration has that data?

Also worked.

Programming is rough. LOL

Next question. given my data structure, how would i add the current iteration of:

RPUID = rg.Cells(i, 6).Value
MDI = rg.Cells(i, 7).Value
InspectionDate = CDate(rg.Cells(i, 16

etc to the key of:

If dict.Exists(RPUID) = True Then ' if exists then
Set BLDG = dict(RPUID)

not sure of the syntax........

Unless your requirements have changed, ie looking for the earlliest date, it doesn't make sense to add the Date to the key.

I have been doing it this way (below):
Some people don't use a delimiter but if you need to troubleshoot it helps if you can read the key.
The delimiter needs to be something that will not occur in your data and the Pipe symbol is a popular choice (I occassionally use "~" (tilda) since it is even easier to read but it takes up more space in the text.
Use Split to break it back into its components.

    Dim dicKey As String
    dicKey = RPUID & "|" & MDI
    If Not dic.exists(dicKey) Then
        ' assign a value or if using an array to store details the array row no
    End If

Yes, next I’ve taken out looking for the lowest date and would like to add each row that has the same RPUID to the key (RPUID). Your explanation flew right over me. Not sure how to implement this. I am posting the entire code below.

    Dim key As Variant, BLDG As Class_BLDG
    Dim row As Long
    row = 2 'start with row 2

    For Each key In dict1
        Set BLDG = dict1(key) 'set each key for instance
        rgOut.Cells(row, 1).Value = key 'output key in this column
        rgOut.Cells(row, 2).Value = BLDG.InspectionDate 'output item in this column
        rgOut.Cells(row, 3).Value = BLDG.MDI 'output item in this column
        'Debug.Print key, BLDG.InspectionDate, BLDG.MDI
        row = row + 1 ' moves to the next row
    Next key 'Moves to next item

End Sub

Unfortunately i cant download L2BB but here is what my data looks like on Sheet2.

What is the aim of the exercise ?
Depending on what you are trying to do using a class object may just complicate things.
Do you have multiple records with the same RPUID MDI & Inspection Date ?
What output are you trying to get to ?
