Feb 2, 2010I'm doing a uni assignment regarding changing decimals to binary. However this assingment seems to be different to most of its kind from what I can see.Our assignment asks us to have a text box in which we'll enter the decimal, then we'll use a menuscript to and highlight the button 'dec-to-bin' which will then change the colour of 8 image boxes (located in a row above the text box) from black to red based on whether the binary is '1' (Red) or '0' (Black) for that bit.I've struggling to find a starting point as I need to ensure I link the text boxes to the outcome of the decimal and binary but not sure how.

Jun 9, 2011So, yes, I've tried with these three formats, and the problem remains the same:I have a string, "s"For Each s As String In stringarray and this array is recieving data from a streamreader that is reading a csv file. The data I'm having dificulty reading are these very specific numbers(yes, only these numbers, because phone numbers get home safe and sound).The numbers I'm talking about are usually decimal.ValueList.Add(Convert.ToDecimal(s))
Now, when I convert them like that, they always bring a "D" alongside with them. I've personally checked the string multiple times, and it just has a "1", and somehow, my list recieves "1D" as a number, same thing happens with decimal numbers(0.29D for example). I've tried with Doubles and Integers, the result is the same.
