These systems had ISA analog/digital i/o cards controlling a test stand that was built to qualify high speed printing press replacement sleeves. I only use PCs when I have no choice, and that pretty much narrows down to needing to supply an X-Y chart which unfortunately industrial controls manufacturers do a crappy job of with their human-machine interfaces.įor ONE of my experience examples, I had two computer-based control systems in Dundee, Scotland that had been installed in the late 1990's/early 2000's and in 2010 I was asked ('turnkey' bid) to upgrade them to modern 64-bit systems (Win 7 Pro was the choice at that time). they go obsolete in a very short time (a year or three) as compared to PLCs that last 20 years or more, and only then get replaced because the parts get too expensive because the manufacturers want you to upgrade to their newer and better models (but also you can get the old parts really cheap on eBay), and secondly, because it is near impossible to bid for a job requiring custom computer programming because you don't know up front how involved it will be to know enough to complete the task.

As a matter of rule, I refuse to implement computers into industrial systems for many reasons, chiefly two- the first is. They use 'Ladder Logic' for the programming environment which is much easier and quicker to work with. While it is fun to program Visual Basic, to tell the truth my main activities are in industrial controls designing the hardware and programming PLCs/PACs to run the equipment. I do NOT want to draw a line in code (which I am well aware of) but I do want to add lines to my forms during design time.ĭoes anyone have any idea how to get the Line control in the Toolbox to be accessible?

When I started a new Windows Form (Framework type) project, I still cannot get either Line control to appear in the Toolbox. But when I added either or both to the Toolbox, they remained disabled. I found the Line control in both the Universal Windows Components tab and the WPF Components tab. Apparently some of the geniuses at Microsoft decided no one needed any 'graphic' elements (Line, Rectangle, etc.) controls in the standard Toolbox, so I went searching for them with the top menu command 'Choose Toolbox items'. Their Toolbox chart control works fine with the project as the 'Framework' type.īut not only could I not get their control to become enabled in the 'Core' project, I also could not get any 'Line' control to become enabled. Sucks because one of the forms has over 10 dozen objects on it with multiple properties set. I tried importing my files into a new 'Framework' project and I got all the code but all of the forms were blank. The vendor advised me that I needed to start the project as a 'Framework' project, not 'Core'. I built 1/4 of a Net 3.1 Core Windows Form project but I could not get a vendor's chart control to become 'enabled' after adding it to the Toolbox.
