How to make the columns in VBscript fixed - vbscript

Question

I'm a beginner in VBscript and I got a script which obtains disk space usage of local drives. However, when some columns would contain long numeric value, some adjacent columns and even values are moving to the right and thus makes the output disorganized. I already
Please see below the contents of the script:
Option Explicit
const strComputer = "."
const strReport = "F:\dba_scripts\diskspace.txt"
Dim objWMIService, objItem, colItems
Dim strDriveType, strDiskSize, txt
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_LogicalDisk WHERE DriveType=3")
txt = "DRIVE" & vbtab & vbtab & "SIZE" & vbtab & vbtab & "USED" & vbtab & vbtab & "FREE" & vbtab & vbtab & "FREE(%)" & vbcrlf
For Each objItem in colItems
DIM pctFreeSpace,strFreeSpace,strusedSpace
pctFreeSpace = INT((objItem.FreeSpace / objItem.Size) * 1000)/10
strDiskSize = round((objItem.Size /1073741824),1) & " GB"
strFreeSpace = round((objItem.FreeSpace /1073741824),1) & " GB"
strUsedSpace = round(((objItem.Size-objItem.FreeSpace)/1073741824),1) & " GB"
txt = txt & objItem.Name & vbtab & vbtab & strDiskSize & vbtab & vbtab & strUsedSpace & vbTab & vbtab & strFreeSpace & vbtab & vbtab & pctFreeSpace & vbcrlf
Next
writeTextFile txt,strReport
wscript.echo "Report written to " & strReport & vbcrlf & vbcrlf & txt
' Procedure to write output to a text file
private sub writeTextFile(byval txt,byval strTextFilePath)
Dim objFSO,objTextFile
set objFSO = createobject("Scripting.FileSystemObject")
set objTextFile = objFSO.CreateTextFile(strTextFilePath)
objTextFile.Write(txt)
objTextFile.Close
SET objTextFile = nothing
end sub
The output file looks OK but when I send/email it using the free bmail, the results are disorganized (meaning some columns and values moved to the right.
My question is are there ways to make the columns and values results fixed ( meaning no columns and values are moving to the right )?

Answer 1

Function RightJustified(ColumnValue, ColumnWidth)
RightJustified = Space(ColumnWidth - Len(ColumnValue)) & ColumnValue
End Function
Usage example:
output = output & _
RightJustified(strDiskSize, 15) & _
RightJustified(strUsedSpace, 15) & _
RightJustified(strFreeSpace, 15) & _
RightJustified(pctFreeSpace, 15) & _
vbCrLf
EDIT
Add the RightJustified function to your script.
Then, replace this line of your code:
txt = txt & objItem.Name & vbtab & vbtab & strDiskSize & vbtab & vbtab & strUsedSpace & vbTab & vbtab & strFreeSpace & vbtab & vbtab & pctFreeSpace & vbcrlf
with:
txt = txt & objItem.Name & _
RightJustified(strDiskSize, 15) & _
RightJustified(strUsedSpace, 15) & _
RightJustified(strFreeSpace, 15) & _
RightJustified(pctFreeSpace, 15) & _
vbCrLf
EDIT 2
I added the RightJustified function at the bottom of your script, and then called it within your loop to format the columns. I also used it on the column headers. Below is the script and at the bottom is the output on my machine.
Option Explicit
const strComputer = "."
const strReport = "F:\dba_scripts\diskspace.txt"
Dim objWMIService, objItem, colItems
Dim strDriveType, strDiskSize, txt
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_LogicalDisk WHERE DriveType=3")
txt = RightJustified("DRIVE", 10) & _
RightJustified("SIZE", 15) & _
RightJustified("USED", 15) & _
RightJustified("FREE", 15) & _
RightJustified("FREE(%)", 15) & _
vbCrLf
For Each objItem in colItems
DIM pctFreeSpace,strFreeSpace,strusedSpace
pctFreeSpace = INT((objItem.FreeSpace / objItem.Size) * 1000)/10
strDiskSize = round((objItem.Size /1073741824),1) & " GB"
strFreeSpace = round((objItem.FreeSpace /1073741824),1) & " GB"
strUsedSpace = round(((objItem.Size-objItem.FreeSpace)/1073741824),1) & " GB"
txt = txt & _
RightJustified(objItem.Name, 10) & _
RightJustified(strDiskSize, 15) & _
RightJustified(strUsedSpace, 15) & _
RightJustified(strFreeSpace, 15) & _
RightJustified(pctFreeSpace, 15) & _
vbCrLf
Next
writeTextFile txt,strReport
wscript.echo "Report written to " & strReport & vbcrlf & vbcrlf & txt
' Procedure to write output to a text file
Sub writeTextFile(byval txt,byval strTextFilePath)
Dim objFSO,objTextFile
set objFSO = createobject("Scripting.FileSystemObject")
set objTextFile = objFSO.CreateTextFile(strTextFilePath)
objTextFile.Write(txt)
objTextFile.Close
Set objTextFile = nothing
End Sub
Function RightJustified(ColumnValue, ColumnWidth)
RightJustified = Space(ColumnWidth - Len(ColumnValue)) & ColumnValue
End Function
Output produced:
DRIVE SIZE USED FREE FREE(%)
C: 48.4 GB 40.6 GB 7.8 GB 16.1
D: 100.6 GB 56.8 GB 43.8 GB 43.5

Answer 2

You could write out a table using HTML. This should work in an email.
