jmcilhinney, I agree with you that it is a lot of work to create a grid control from scratch. But, does that mean that I should pay $1000 for this module or $100? I'm using several modules that are free. One example is a real-time scope graph that is showing amplitude vs time. This module has a lot of functions like, auto scaling, customized colors, filtering etc. etc. I'm sure there is a lot of work to make this module from scratch as well, but you can get it for free, it is a open source project. I'm willing to pay for modules too, and I often do that.
I hope you understand my intention a little better now. I'm just reaching out to my fellow software developers to kindly ask for some advice. I chose this forum because it seems to be a fairly active and serious forum. A big thank you to you and however else is running it.
