    Pls help with "Class is not licensed for use" error

    Hi,

    I am using mscomm in my vb.net project. When using on my development machine, all is fine. When distribute the the app I get "Class is not licensed for use" error. I checked that the component is installed. When I use a vb6 project that uses the same mscomm component, there is no error.

    Does anyone have a solution for me?

    Thanks

    Next problem!

    The control sends data without a problem, but I am not receiving anything back.

    Glad you got it figured out . We hope MS releases a similar .NET Control rather than working backward .

    K! Here is the final solution...

    You cannot just create a variable of type mscomm. This will result in the licensing error. You must place the control on a form. If you do it this way, you will not have to install the vb6 development environment.
