    NumericUpDown for touchscreen

    Perhaps someone will find this useful. I'm new to .Net so this is my first CodeBank submission and first UserControl. Kudos to circuits2 for his post that provided the main inspiration to tackle this as a UserControl instead of individual components.

    The app I'm rewriting uses touchscreens and the controls used in VB6 don't exist anymore. This uses 2 pairs of buttons for coarse or fine "steps" since that was another way it had been done in the past so the operators are familiar with it. You could alter to only one button and have a timer to repeat it if you want. It will resize a bit and may be done better than I did perhaps. Left size (75x215) is the minimum and it will go to 300x1000 (right one is 200x499). Smallest size should allow 5 digit integers (if you don't alter the font).

    I'm using this with .Net 4.5 so I don't know if there would be any issues with older versions.
