d12292 | In my opinion the best way might be a join of the two dataframes and then you can model the conditions in the when clause. I think if you create a new column with withColumn it iterates over the values from the current dataframe, but I think you can not access values from another dataframe and expect it also iterates t... | |
d12293 | This pretty much unambiguously says the server says the server has no messages in the INBOX:
A1 SELECT INBOX
* 0 EXISTS
* 0 RECENT
Either they are in another folder, or they are in another account. | |

d12295 | The reason it flickers is because when you assign the width or height to a canvas element, this action resets the entire context of the canvas, most likely that is causing the blank frame. Try moving all the canvas/context definitions outside the drawCanvas.
Something like:
var elem = document.getElementById('c');
var ... | |
d12296 | Please try the following solution based on XML and XQuery.
Notable points:
*
*We are tokenizing input string as XML in the CROSS APPLY clause.
*XQuery's FLWOR expression is checking for numeric integer values with
a particular length, and substitutes then with a replacement string.
*XQuery .value() method outputs b... | |
d12297 | sample_string.erase(i,j)
Calls the erase method on the sample_string object (assuming that this is an instance of a class that implements this method).
string(sample_string).erase(i,j)
Creates a temporary instance of the string class, calling a string constructor using the sample_string object for initialization ... | |
d12298 | Here was an incorrect solution.
Counterexample for your solution. Suppose, that one in square is the only one important. Your solution will delete one road.

d12300 | The FRC will only observe changes to the objects that it is directly interested in, not any of the objects that they are related to.
You should configure your own observation, either directly with KVO or to the context being saved, and use that to trigger a UI refresh. |
