You should not redeclare the variable twice but only modify its value: for (int i = 0; i < Model.Items.Count; i++) { string SelectedEvent = “event selected”; if (i > 1) { SelectedEvent = “event”; } // here you can use the SelectedEventVariable // its value will be “event selected” on the first and second … Read more
A simple answer is “statements are not allowed in class body”. The simplest fix for you program would be creating an instance list variable like. private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { final SayingsHolder holder = (SayingsHolder).getApplication(); ArrayList<String> sayingsList = holder.getSayingsList(); } This is just one option. You can move this holder.getSayingsList(); to a method body … Read more
You’re passing the pointer by value, so inside the function you’re actually assigning to a new pointer, not the original one. Change the function prototype to void StrIn(char *&sp). 1 solved Whats wrong with the Null pointer [closed]
Use the information_schema meta-DB: SELECT COLUMN_NAME FROM information_schema.TABLES WHERE (TABLE_SCHEMA=’Yourdb’) AND (TABLE_NAME = ‘Yourtablename’) solved Echo name of fields from MySQL table to web page [closed]
This has nothing to do with statics whatsoever. Your problem can be reproduced with a much smaller piece of code that has no static variables in it at all. The compilation error is very clear: main.cpp: In function ‘int main()’: main.cpp:12:1: error: jump to label ‘b’ [-fpermissive] b: ^ main.cpp:9:10: error: from here [-fpermissive] goto … Read more
This won’t end up well. The problem is that sometimes there are float errors when representing numbers in binary (which is what your computer does). For example, when adding 1 / 3 + 1 / 3 + 1 / 3 you might get 0.999999… and the number of decimal places varies greatly. ravi already provided … Read more
You can get the result from the below code. String string = “123454466666666666666665454545454454544598989899545455454222222222222222”; int count = 0; for (int i = 0; i < string.length(); i++) { count += Integer.parseInt(String.valueOf(string.charAt(i))); } System.out.println(count); 0 solved Datatype for getting input for over 30 digits
If you want to use a range, then you need to call the function: for j in range(row): range is not part of the Python syntax, it is just another built-in object type. 1 solved Syntax error in a for loop in python [closed]
return print(char) This will first print the value of char (as in print(char)) and then try to return the return value of the print function. But since the print function always returns None—it only prints the value, it does not return it—your function will always return None causing the error when trying to concatenate None … Read more
I think you should be using name_choice here instead of name if name == “Sam”: print (“Your name is Sam”) What is the name variable meant for anyway? A good tip when something like this happens is to print the things you are comparing right before the if eg print (“name ==”, name) if name … Read more
Since border radius (and other CSS3 properties) is not supported in older browsers, you can use CSS3 Pie for example. Keep in mind that you are referring to styling not to scriping. So asking if it can be done with jQuery is a bit weird. solved How to use Border Radius CSS on Internet Explorer
You can convert both dates to seconds with timeIntervalSince1970 and then check if difference is bigger than 2592000 (30*24*60*60 which is 30 days * 24 hours * 60 minutes * 60 seconds). NSTimeInterval difference = [date1 timeIntervalSince1970] – [date2 timeIntervalSince1970]; if(difference >2592000) { //do your stuff here } EDIT: For more compact version you can … Read more
This is how a stack works: You push elements into it like this. The freshly added elements are always “on top” since it is a Last in First Out (LIFO) structure. You can only access the top element: Then You can pop these elements, but pop always removes the top one, like this: If i … Read more
Hint 1: Compare the result of your ziprev with List.zip [1,2,3,4] [10,20,30,40] You should see a fairly obvious pattern. Hint 2: List.rev reverses a list. Hint 3: Can you use zipW to implement List.zip? That is, if you want to say normalzip xs ys = zipW something xs ys what would something be? solved SML … Read more
Today I tried a content slider, with fixed pagination. I implemented this for something, which I would say after it is released. I could have simply used a plug-in, but due to some technical issues, and I too wanted to learn something, so I did it on my onw. I started with the HTML Markup, … Read more
