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

_ADO_OLEDBProvidersList()

Func _ADO_OLEDBProvidersList()
	Local $sKey = "HKCR\CLSID", $iIndexReg = 1, $iIndexResult = 0

	Local $aResult[200][3]
	Local $sTitle = "OLE DB Providers"

	ProgressOn($sTitle, "Processing the Registry", "", Default, Default, $DLG_MOVEABLE)

	; Count the number of keys

List all properties of an open ADO connection

This tool lists all properties for an open connection.

#include <Array.au3>
#include <MsgBoxConstants.au3>

_Example_ListProperties()

Func _Example_ListProperties()
	Local $oADOConnection = ObjCreate("ADODB.Connection") ; Create a connection object
	If @error Then Exit MsgBox($MB_ICONERROR, "Error", "Error " & @error & " creating the connection object!")

	; Open the connection
	Local $sADOConnectionString = 'Provider=Microsoft.Jet.OLEDB.4.0;Data Source=' & @ScriptDir & ';Extended Properties="Text;HDR=NO;FMT=Delimited(,)"'
	$oADOConnection.Open($sADOConnectionString)
	If @error Then Exit MsgBox($MB_ICONERROR, "Error", "Error " & @error & " opening the connection object!")

	Local $aProperties = _ADO_Connection_PropertiesToArray($oADOConnection)

	_ArrayDisplay($aProperties, "ADO connection - List of properties", "", 0, Default, "PropertyName|PropertyValue")
	
EndFunc    ;==>_Example_ListProperties

Func _ADO_Connection_PropertiesToArray(ByRef $oConnection)
	Local $oProperties_coll = $oConnection.Properties
	Local $aProperties[$oProperties_coll.count][2]
	Local $iIndex = 0

	For $oProperty_enum In $oProperties_coll
		$aProperties[$iIndex][0] = $oProperty_enum.Name
		$aProperties[$iIndex][1] = $oProperty_enum.Value
		$iIndex += 1
	Next

	$oProperties_coll = Null
	Return SetError($ADO_ERR_SUCCESS, $ADO_EXT_DEFAULT, $aProperties)

EndFunc    ;==>_ADO_Connection_PropertiesToArray

Result:

Connection Properties
