Programmatic dial-up using ActiveX or whatever with Labview.

[dfa_employee]

We are trying to dial-up a internet provider programmatically to send data to a ftp site. Is there an easy way to do this? Basically, dial-up, download and then disconnect.

The internet toolkit is your best bet. It contains self contained VIs to do this, with the possible exception of dialup.

I would suggest looking on the example programs database or doing a search. Someone out there has to have something to do a dialup. If you have an external (serial) modem, then it is a simple matter of getting the command line. If it is an internal, same thing applies, but you may have to use a dll call or something. I am sure someone out there has done this before.

Don't rely on ActiveX. It is primarily for doing interface with platform specific, manufacturer specific applications on a specific platform. Using it is not only complicated, but also limits the application of your program. I ALWAYS try to avoid platform specific programming.


Browse NI's support and here for downloads that may help you. The folks here are always willing to help.

Good luck

A way to do it is:
1. start the connection app with
"rundll rnaui.dll,RnaDial "
2. if you need to do some other operations (like password or closing the connection) control this app simulating key press action with SendMessage() Windows API function (detailed doc in MSDN Library)

I know it' s not simple at all, but if you don't have anything else ...
good luck
