I'd love to help you Azdonald, but you really haven't given me any information about what you want to do... at all...
I understand you want to interface with a scale of some sort using WinWedge to collect data into your software? Have you determined that WinWedge is the best solution for what you are trying to do, or is it something that seemed like it might work?
WinWedge should have come with a Library you can import and use to interface with devices. More importantly, WinWedge comes with a manual that has all sorts of examples of how to use it with your device both programming and integrating with Microsoft Excel. (I should note here that I never worked with this software, I only know of it because our lab techs have it and my Supervisor got it working with our inventory application)
This is how I would approach this problem:
0------I would read that manual
1. I would identify all of the data I need collected
2. I would build a separate application, a test project, in which I would interface with the target device and learn to collect the data
3. Now that I know what I am doing, I go back to my application and decide how to integrate that method into what I have
4. Now I know what I am doing, I finish my product
