    Hey, I am making a SIMPLE parallel/series resistance calculator and wondered
    if anyone wanted to test it...

    I'm sorry but it is programmed in and I might switch it to C/C++
    someday but for now it is going to require the .NET framework. Anyway, if
    you want to try it let me know what you want added. The next step I was
    going to do is show the voltage dropoff of each resistor. Oh well... Let me
    know what you think.

    Not half bad.. here are some suggestions..

    1) ad a power of ten (ie 330e3 = 330,000) button
    2) make hotkeys for clear and calculate buttons
    3) add a thing to do caps in paralell and series.. just gotta flip the
    formulas from the resistors.. While your at it do inductors :)
    4) maybe add a keypad looking thing like when you use the windows
    calcuator.. Either that or scale down the GUI, there is a lot of empty

    The math seemed alright tho.. i tryed out a few calculations and it came
    up right every time..

    Hope my comments helped! i'm not very experienced using C++ or i'd
    probabally just write out code for what i thought needed fixing.. seems
    like your on your way to an alright program tho..

    good luck

    Good thought...
    Another good thought...
    Was just thinking about that... :)
    Never thought about that.... :) :)
    Yeah, I should, I just never liked the GUI keyboard but I see your point.
    Yeah, I knew that was coming. I left it big for my future add-ons.
    Yeah, I am only using the reciprical of the sum of recipricals to keep the
    logic down, and there isn't a lot of ways I can screw that one up. It has
    worked on all of my tests and there is a limit on the number of resistors to
    avoid wrapping the value and giving false results.

    It's actually Visual BASIC.NET. I do program in C/C++ and JAVA though. This
    was just a little app to get me into the .NET framework. Not sure that I
    like .NET but it isn't that bad....
