List all installed OLE DB providers

This tool lists all available providers installed on the computer. You get the registry key, the name of the provider (as to be used in the connection string) plus a description of the provider.

Idea taken from http://www.motobit.com/help/RegEdit/sa117.htm

#include <Constants.au3>
#include <Array.au3>
Global $sOutput, $oRegistry, $oKey, $sKey = "HKCR\CLSID", $iIndexReg = 1, $iIndexResult = 0
Global $aResult[200][3], $sTitle = "OLE DB Providers", $iMax = 100000, $iMin = 1, $iPrevious = $iMin, $iCurrent = $iMax/2, $iTemp
ProgressOn($sTitle, "Processing the Registry", "", Default, Default, $DLG_MOVEABLE)
; Count the number of keys
While 1
    RegEnumKey($sKey, $iCurrent)
    If @error = -1 Then ; Requested subkey (key instance) out of range
        $iMax = $iCurrent
        $iCurrent = Int(($iMin + $iMax) / 2)
        $iPrevious = $iMax
    Else
        If $iPrevious <= ($iCurrent + 1) And $iPrevious >= ($iCurrent - 1) Then ExitLoop
        $iMin = $iCurrent
        $iCurrent = Int(($iMin + $iMax) / 2)
        $iPrevious = $iMin
    EndIf
WEnd
; Process registry
While 1
    If Mod($iIndexReg, 10) = 0 Then
        $iPercent = Int($iIndexReg * 100 / $iCurrent)
        ProgressSet($iPercent, $iIndexReg & " keys of " & $iCurrent & " processed (" & $iPercent & "%)")
    EndIf
    $sSubKey = RegEnumKey($sKey, $iIndexReg)
    If @error Then ExitLoop
    $sKeyValue = RegRead($sKey & "\" & $sSubKey, "OLEDB_SERVICES")
    If @error = 0 Then
        $aResult[$iIndexResult][0] = $sKey & "\" & $sSubKey
        $aResult[$iIndexResult][1] = RegRead($sKey & "\" & $sSubKey, "")
        $aResult[$iIndexResult][2] = RegRead($sKey & "\" & $sSubKey & "\OLE DB Provider", "")
        $iIndexResult = $iIndexResult + 1
    EndIf
    $iIndexReg = $iIndexReg + 1

ReDim $aResult[$iIndexResult][3]
_ArrayDisplay($aResult, $sTitle, "", 0, Default, "Registry key|OLE DB Provider|Description")

Result:

OLE DB Providers
