Parametrized ADO Commands.

[Gutes]

I've big trouble whe assigning parameters to a Command which ActiveConnection property was asigned by a Connection object whithout a DSN (that means, by manually assigning the ConnectionString).
The problem is, that when I try to access a Parameter from the Collection Parameters, it returns an Error.

Do I have to create again each parameter in VB?

for example :
MyCommand.Parameters.Refresh
number=MyCommand.Parameters.Count

number has 0 in its value.

I've tried creating a ADODB.Parameter Object, but the problem is when I simply don't know, how many parameters does the Command have.
