-

i getting bug, wrote code below

code:

decimal amnt; decimal.tryparse(txtamnt.text, out amnt); int tnure=1; int.tryparse(txttnre.text, out tnure); txtddctamnt.text = (amnt /tnure).tostring("0.00");

when in textbox value 0 getting error.if possible give answer me.

how using if check before dividing zero?

if(tnure != 0)     txtddctamnt.text = (amnt / tnure).tostring("0.00"); else     txtddctamnt.text = "invalid value";

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
