Getting 16 bit app communicating with 32 bit Labwindows app

[JLahens]

Hello,
I am working with a 16 bit application written in Turbo Pascal.  I want to upgrade this code so that it communicates over a USB port rather than through an interrupt driven DMA process involving a card that sits on an ISA slot.  I'm interested in using a winsocket to allow the 16 bit application to communicate with a 32 bit Labwindows app.  Does anyone have more information on this topic and/or examples of how I can do this using LabWindows/CVI?

Thanks,

JLahens

Hello JLahens,

I haven't specifically done this myself, but I did a few Google searches and found some MSDN documentation that might be helpful to you even though it's ODBC related.

What is "Thunking" and What Role Does it Play in CVI's 32-bit Environment, or in General?
MSDN: Using 16-bit Applications with 32-bit Drivers

Hope that helps, and if anyone else has additional info, please feel free to post.

Thanks
