Here are two tutorials you should take a look at: Java applets: http://docs.oracle.com/javase/tutorial/deployment/applet/ Implementing Policy: http:/

问题 I'm working on a project using jQuery to make a currency converter. I'm getting the currency info from an api service and loading it up in a table with multiple currencies. After which, I want to be able to enter a number in one input and make the other inputs produce the correct currency according to the entered input. As you can see in the following code, I'm trying to make the keyup function work on everything but the input of which the numbers are being entered at that moment. My output

问题 It seems like it is not possible what I want(at least according to some articles i have read). But just to double check it. I am reading a DateTime from my database. In the database it is written like "01.01.2011" but when I read it with SQL and store it in a string it says "01.01.2011 00:00:00". Then I thought OK, I will just cut the time from the string .

问题 Currently I'm making an application and try to get a value from a textBox and convert it then to an integer for further use. I have the following code: System::String^ maxTTL = textBoxMaxTTL->Text; std::string bla = marshal_as<std::string>(maxTTL); //System string^ to std::string int maxTTL2 = std::atoi(bla.c_str()); It seems that maxTTL2 still got the value of '0'. When I use the stoi argument it throws the following exception: stoi argument out of range. Has somebody an idea to resolve this

问题 I'm working with the Vaadin Framework at the moment. I want to convert the string in my DateField to Date .

问题 Let's say I have a text file contains a bunch of cidr ip ranges like this: x.x.x.x/24 x.x.x.x/24 x.x.x.x/23 x.x.x.x/23 x.x.x.x/22 x.x.x.x/22 x.x.x.x/21 and goes on... How can I convert these cidr notations to all possible ip list in a new text file in Python? 回答1: If you don't need the satisfaction of writing your script from scratch, you could use the python cidrize package. 回答2: You can use netaddr for this. The code below will create a file on your disk and fill it with every ip address in

问题 I decided to open this topic because there is very little material in this regard and in my opinion many are asking the same question. I'm trying to write an script to convert an .xls or a .xlsm file stored on Google Drive to a Google Sheets file. I'm not interested in converting macros inside the .xlsm file, only converting the base file. This script should be able to overwrite the oldest file with the new one if it has the same name. The topics in which I found more material are these: How
