As you mention you are getting Error 126 This sounds like an error message that would be generated by a VB6 based application and not a .NET application.
Are you using VB.NET or and earlier version of VB.
If this question does relate to VB6 then the following applies if your using .NET then you need to provide more information.
These forums are for VB.NET and there are better places to find answers for older versions of VB such as VB6.
Maybe the VB6 newgroups - http://msdn.microsoft.com/newsgroups/default.aspx?dg=microsoft.public.vb.general.discussion&lang=en&cr=US
or the VB6 resource center
http://msdn.microsoft.com/vbrun/
or web sites such as www.vbcity.com
You could however download VB Express and start working with .NET technology - its free to download from microsoft web site.
Hope these point you in the right direction.
