Deduplication and filtering of Add/Remove Programs list (VBScript)

Question

This script works and tells and me what is installed in Program files.

Two problems

Duplicate lines

i.e

AVG 2011 Ver: 10.0.1204

AVG 2011 Ver: 10.0.1204 Installed: 27/01/2011

and

I don't want to include lines that have key words "Update","Hotfix","Java" can any VB gurus out there help with what extra is needed in this script?

Option Explicit

sTitle = "Installed Programs on your PC -"

Answer 1

@icecurtain: The second part of your question can be solved using InStr as suggested by @Oliver, rewritten to suit your script it would look like --

If sValue <> "" _
    AND (InStr(1, sValue, "Hotfix", 1)) = 0 _
    AND (InStr(1, sValue, "Update", 1)) = 0 _
    AND (InStr(1, sValue, "Java", 1)) = 0) Then

The first part wouldn't be that tricky either except for the fact that you include a version and installation date if found (which some of the duplicates will only include in part or not at all). If the extra bits of data wasn't included, you could loop through all the lines and add them into a Scripting.Dictory object with a .Exists check to prevent a duplicate from being added.

Answer 2

Ok, even if i'm not a jedi master (or have no self-respect ;-)), this could help you:

If InStr(1, sValue, "hotfix", vbTextCompare) = 0 Then
    Print "This is NOT a hotfix"
End If

For further informations just take a look at the MSDN page for InStr().

Answer 3

I don't think hardcoded string checks are the way to go, a uninstall entry is a update if any of these are true:

• It has a dword value named SystemComponent that is <> 0
• A string value named ParentKeyName
• The registry sub key starts with "KB" or "Q" + 6 numbers (KB######,Q######)
