Welcome to my current life. Over the last several years my group has gone from 17 people in three departments to 5 in a single department. We're still supporting everything. I spend more than half my time debugging and fixing other people's crap, and many of the problems are like the one you describe. People who took shortcuts, made stupid assumptions, or were just :elephant:ing sloppy. I spent close to a year debugging a problem in some embedded software that was caused by the original author not re-initializing some control values on an Ethernet error. It was the kind of excreta that doesn't happen in a robust, conscientious design.

They were there for "design" ideas. You were asking for "best ways to code" (i.e. "patterns"). (I personally have never written a lick of VB.NET). But I see you get the idea: find a mouse trap (sample app) and build a better one. "Before entering on an understanding, I have meditated for a long time, and have foreseen what might happen.

You've posted this in the wrong forum. Your question has absolutely nothing to do with writing a CodeProject article. And quite frankly, from the description of what you're trying to do, I suspect nobody will want to help you. We all get plenty of spam already, without helping someone else set up a spam farm. And even if you somehow manage to get it working, Google will hopefully detect the malicious activity and suspend your 150 GMail accounts.

I missed the joke. Thank You for clarification. As to rotation I of course have no idea as it is not my control. However in my next project I am looking forward to considering animated controls even perhaps 3D. - Best

thanks for your great input. :rose: I saved your link for my use. diligent hands rule....

Binding? You mean not showing progress on loading, just a non responsive UI? :D Is that a thing? :wtf: Bastard Programmer from Hell :suss: "If you just follow the bacon Eddy, wherever it leads you, then you won't have to think about politics." -- Some Bell.

>> add a column for it, but don't use the PK. That will require creating another table to handle the numbering for your application plus coding to handle the incremented value in that column, well, simply, I don't bind the PK, I handle it manually.

I've never really had any formal electronics training, so a few decades ago, I was rather happy with myself having hooked up a discarded 2-line LCD display unit (the kind you used to find attached to cash registers) to a serial port, with no documentation whatsoever, and figuring out settings (parity, baud rate, data bits, etc) through trial and error, to make it display any string sent to it. I turned it into a simple clock showing full date and time. Definitely not much of a thing compared to what some people here manage to do, but it was enough for coworkers called me a nerd when they saw it. I wore that badge with pride...
