excel – Cleaning VBA code to reference code instead of duplicating it

Posted by: admin May 14, 2020 Leave a comment

Questions:

I have coded a form for entering product information that works and would like to clean it up. Currently for every product division, I have copied and pasted the same code to take the values from the form and apply them to the correct division sheet. I would like to have the code occur once, and then reference it in the code for the 22 divisions. I have not been able to find a solution to this, likely because I do not know the proper terminology.

Here is a section of what I would like to fix:

Case "DIVISION 21 - FIRE SUPPRESSION"
Set ws = Sheets("Div-21")

LastRow = ws.Range("C" & Rows.Count).End(xlUp).Row + 1
ws.Range("b" & LastRow).Value = Specs_Number
ws.Range("c" & LastRow).Value = Specs_Name
ws.Range("d" & LastRow).Value = Me.TextBoxProduct_Generic_Name.Value
ws.Range("e" & LastRow).Value = Me.TextBoxProduct_Manufacturer.Value
ws.Range("s" & LastRow).Value = Me.TextBoxAuthor_Initials.Value
ws.Range("f" & LastRow).Value = Me.TextBoxModel_Name.Value
ws.Range("k" & LastRow).Value = Me.TextBoxProduct_Serial_Number.Value
ws.Range("g" & LastRow).Value = Me.TextBox_Website_Link.Value

ws.Range("m" & LastRow).Value = Me.TextBoxSales_Rep_Name.Value
ws.Range("n" & LastRow).Value = Me.TextBoxSales_Rep_Phone.Value
ws.Range("o" & LastRow).Value = Me.TextBoxSales_Rep_Email.Value


Case "DIVISION 22 - PLUMBING"
Set ws = Sheets("Div-22")

Any help would be appreciated. If possible, please explain in a clear and detailed way since I am still very much a novice at VBA coding and a beginner at coding in general.

How to&Answers:

The part that changes is ws. Keep the Select Case and move the repetitive block afterwards.

    Case "DIVISION 21 - FIRE SUPPRESSION"
         Set ws = Sheets("Div-21")
    Case "DIVISION 22 - PLUMBING"
         Set ws = Sheets("Div-22")
    Case "DIVISION 22 - PLUMBING"
         Set ws = Sheets("Div-23")
    ...
    Case Else
         ' handle other cases, perhaps `Exit Sub`
End Select

' Now you need only one instance of the repetitive block
' You've got the right `ws` from above.

LastRow = ws.Range("C" & Rows.Count).End(xlUp).Row + 1
ws.Range("b" & LastRow).Value = Specs_Number
ws.Range("c" & LastRow).Value = Specs_Name
... and so on

If you are dealing with a repetitive DIVISION - ## - .... pattern, then you could refactor your Select Case into a separate function that parses the sheet name instead of listing all the possibilities as you currently do.

Answer:

Looking to not repeat code is great thing. In this case you can simply just do the following:

Case "DIVISION 21 - FIRE SUPPRESSION"
Set ws = Sheets("Div-21")

Case "DIVISION 22 - PLUMBING"
Set ws = Sheets("Div-22")

End Select

LastRow = ws.Range("C" & Rows.Count).End(xlUp).Row + 1
ws.Range("b" & LastRow).Value = Specs_Number
ws.Range("c" & LastRow).Value = Specs_Name
ws.Range("d" & LastRow).Value = Me.TextBoxProduct_Generic_Name.Value
ws.Range("e" & LastRow).Value = Me.TextBoxProduct_Manufacturer.Value
ws.Range("s" & LastRow).Value = Me.TextBoxAuthor_Initials.Value
ws.Range("f" & LastRow).Value = Me.TextBoxModel_Name.Value
ws.Range("k" & LastRow).Value = Me.TextBoxProduct_Serial_Number.Value
ws.Range("g" & LastRow).Value = Me.TextBox_Website_Link.Value
AddLink ws.Range("i" & LastRow), Me.TextBoxPicture_File_Link.Value
ws.Range("j" & LastRow).Value = Me.TextBoxColor.Value
ws.Range("r" & LastRow).Value = Me.TextBoxLocal_Locations.Value
ws.Range("l" & LastRow).Value = Me.TextBoxFeatures.Value
ws.Range("h" & LastRow).Value = Me.TextBoxComments.Value
ws.Range("m" & LastRow).Value = Me.TextBoxSales_Rep_Name.Value
ws.Range("n" & LastRow).Value = Me.TextBoxSales_Rep_Phone.Value
ws.Range("o" & LastRow).Value = Me.TextBoxSales_Rep_Email.Value

But as you are learning about how to “trim down code”, I wanted to cover also calling a sub with arguments, like so.

Sub SheetSelect()

Dim ws as worksheet 

Case "DIVISION 21 - FIRE SUPPRESSION"
Set ws = Sheets("Div-21")
Call DoStuff(ws)

Case "DIVISION 22 - PLUMBING"
Set ws = Sheets("Div-22")
Call DoStuff(ws)

End Select
End Sub

Sub DoStuff(ws As WorkSheet)

LastRow = ws.Range("C" & Rows.Count).End(xlUp).Row + 1
ws.Range("b" & LastRow).Value = Specs_Number
ws.Range("c" & LastRow).Value = Specs_Name
ws.Range("d" & LastRow).Value = Me.TextBoxProduct_Generic_Name.Value
ws.Range("e" & LastRow).Value = Me.TextBoxProduct_Manufacturer.Value
ws.Range("s" & LastRow).Value = Me.TextBoxAuthor_Initials.Value
ws.Range("f" & LastRow).Value = Me.TextBoxModel_Name.Value
ws.Range("k" & LastRow).Value = Me.TextBoxProduct_Serial_Number.Value
ws.Range("g" & LastRow).Value = Me.TextBox_Website_Link.Value
AddLink ws.Range("i" & LastRow), Me.TextBoxPicture_File_Link.Value
ws.Range("j" & LastRow).Value = Me.TextBoxColor.Value
ws.Range("r" & LastRow).Value = Me.TextBoxLocal_Locations.Value
ws.Range("l" & LastRow).Value = Me.TextBoxFeatures.Value
ws.Range("h" & LastRow).Value = Me.TextBoxComments.Value
ws.Range("m" & LastRow).Value = Me.TextBoxSales_Rep_Name.Value
ws.Range("n" & LastRow).Value = Me.TextBoxSales_Rep_Phone.Value
ws.Range("o" & LastRow).Value = Me.TextBoxSales_Rep_Email.Value

End Sub

I don’t know what it accepted practice/best policy, but I often put separate subs in separate modules so that I don’t have modules that are super long. I also have a “main” module which only calls each sub that does something. This allows me to comment out subs for debugging and re-introduce them one by one.

Eg:

Sub Main_Sub()

Call First_Task

'Call Second_Task ' Comment out "Second Task" for debugging till "First_Task" works as expected, this also allows for future debugging.

End Sub
