VBScript: ADODB Connection to Excel Variable Range

Posted by: admin May 14, 2020 Leave a comment

Questions:

I’ve got some working code here that I’m trying to improve with an integer to alphabet solution.

I have a massive Excel Spreadsheet that the user will address with ADODB to a specific Range based on their input (to reduce the recordset size).

So, if the input is 1 the range is A1:H51 and if the input is 2, its offset by 8 fields.

Right now, as you can see below, I’m just doing 50 If Then Statements. My question is how can I use a variable to set the range based on the input?

Or is it good enough as is? Seems complicated…

Dim SelectedSpreadsheetFromTxt
Dim fso
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set file = fso.OpenTextFile("C:\ProgramData\vizrt\Trio\GolfShotSheetSpreadsheetPath.txt")
    line = file.ReadLine
    file.Close

SelectedSpreadsheetFromTxt = line

Dim Message,Flag,Name,Score,Hole,Par,Shot,NullField
Dim objConnection, objRecordSet

    set objConnection = CreateObject("ADODB.Connection")
    set objRecordSet = CreateObject("ADODB.Recordset")

    objConnection.Open "Provider=Microsoft.ACE.OLEDB.12.0;" &_
    "Data Source=" & SelectedSpreadsheetFromTxt & ";" &_
    "Extended Properties=""Excel 12.0; HDR=Yes; IMEX=1"";"

How to&Answers:

If you opened the workbook then you could have used the offset function of the range object. Then you could do something like

baseRange = Range("A1:H51")

If SheetFromInput > 1 Then
    ShotRange = baseRange.Offset(0, (SheetFromInput - 1) * 8)
Else
    ShotRange = baseRange
End If

but since you are doing a query then you need to create the function to get the alpha characters. You do this by using the ascii values for A-Z:65-90. Dividing by 26 and starting at 64 since 1 = A and 64+1 is the aschii value for A.

*Note that this is not fully tested and could probably be done more efficiently

If SheetFromInput > 1 Then
    ShotRange = "Shot_Graphics$" & getRangeAlpha((SheetFromInput - 1) * 8 + 1) & "1:" & getRangeAlpha((SheetFromInput - 1) * 8 + 8) & "51"
Else
    ShotRange = "Shot_Graphics$" & getRangeAlpha(1) & "1:" & getRangeAlpha(8) & "51"
End If




Function getRangeAlpha(val)
'Ascii 65-90 A-Z
'divide by 26
Dim numLetters
Dim numRemainingLetters
Dim letterRange

numLetters = val \ 26
numRemainingLetters = val Mod 26
'check to see if we are at ZZ (702)
'we do this as 27 returns AA in this function.  This is the only known issue.
If numLetters = 27 Then
    getRangeAlpha = "ZZ"
    Exit Function
End If
'check to see if we have three letters
If numLetters > 26 Then
    Dim numThirdLetter
    'get the value for the third letter (first in series)
    numThirdLetter = numLetters \ 26
    'set the next letter to the remaining value
    numLetters = numLetters Mod 26
    'add the letter
    letterRange = Chr(64 + numThirdLetter)
End If

If numLetters > 0 Then
    letterRange = letterRange + Chr(64 + numLetters)
End If
If numRemainingLetters > 0 Then
    letterRange = letterRange + Chr(64 + numRemainingLetters)
End If

getRangeAlpha = letterRange
End Function
