In the "KeyDown" eventhandler, if the "e.KeyValue" is a number, I want to treat it as a number and store it as an int. So, if I hit "8" on the number pad, I don't want "Numpad8" I want the int value 8 that I can add or subtract or whatever. So, how do I convert from the KeyValue to an int? 回答1: I'd go with this solution: int value = -1; if (e.KeyValue >= ((int) Keys.NumPad0) && e.KeyValue <= ((int) Keys.NumPad9)) { // numpad

Eg char(ascii_codes) ? 回答2: A great alternative to the char function, in my opinion, is the native2unicode function. It handles many different encoding

It's my sample in codepen 回答1: You can do it with angular.fromJson() in your sample, it would have been $scope.tmp = angular.fromJson($scope.text); The difference between JSON.Parse() and angular.fromJson , is that angular will check to make sure a string is

It looks like this: Row[(daytetime='2016_08_21 11_31_08')] Is there a way to convert this unorthodox yyyy_mm_dd hh_mm_dd format into a Timestamp? Something that can eventually come along the lines of df = df.withColumn("date_time",df.daytetime.astype('Timestamp')) I had thought that Spark SQL functions like regexp_replace could work, but of course I need to replace _ with - in the date half and _ with : in the time part.
