How can I give my application to client? I work with Access 97 and use SQL Toolkit 5.0. NI must sell one license to client for distributed this application.
License for what? Are you giving him a built application or the source files? If a built application, I think the only license requirement for the SQL Toolkit is if you use the Intersolv drivers that come with it.
But I must install SQL Toolkit 5.0 for execute my application (.EXE), in other hand my application generate errors. But I can't give an installer application to client, if is neccesary install SQL Toolkit.
You don't need the entire toolkit. You need about a dozen .dll's that you include in your installation program. I don't have the list files handy but you should be able to find it in NI's Knowledge Base.
When I acquired the SQL Toolkit 4 years ago a license was needed to distribute the applications developed, the price was approx. 300-400 USD. I don't know if this has changed, you should contact your NI dealer.
