user-input

I would like to allow the user of my app to pick a location in the map. The native map has a "drop pin" feature where you can locate something by dropping a pin. How can I do this in MapKit? RedBlueThing You need to create an object that implements the MKAnnotation protocol and then add that object to the MKMapView : @interface AnnotationDelegate : NSObject <MKAnnotation> { CLLocationCoordinate2D coordinate; NSString * title; NSString * subtitle; } Instantiate your delegate object and add it to the map: AnnotationDelegate * annotationDelegate = [[[AnnotationDelegate alloc] initWithCoordinate

I have a simple program that prompts user to enter number between 1-9 and if the number has been entered previously it will ask the user to enter another number. The user has 10 tries or attempts. This is only part of what I wanted to do but I am having problems passing the parameter from the getNum method to the method that calls it. If I enter the number between 1-9, it has no problem. The problem starts when I entered the number previously entered and the prompts ask for another number. def getNum(numList): num = input("Pick your number: ") if num <= 0 or num >9: print 'Invalid number.

I have a trivial question to ask. My program should take postive integers only. If there is anything illegal, the user should be prompted to input a number again. The code I have for now is: #include<stdio.h> int main(){ int reads; int num=0; char a; while(num<=0){ printf("Please Enter positive integer: "); while(((reads = scanf("%d%c", &num, &a)) != 2 && reads != EOF) || a != '\n' ){ do { printf("Please Enter positive integer: "); reads = scanf("%c", &a); }while(reads != EOF && a != '\n'); } } printf("Num is: %d", num); } The code above almost did what I want; however, when the input is

I have only one method main. How to check System.out.println() and replace Scanner to input values automatically using JUnit? P.S. Please, provide some solutions... public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int[] arr = new int[4]; for (int i = 0; i < arr.length; i++) { arr[i] = scanner.nextInt(); } for (int i = 0; i < arr.length; i++) { int res = 0; int k = 0; int num = arr[i]; /*.....*/ System.out.println(num); } } Ideally, extract the awkward dependencies so that you can test without them. Change main to simply: public static void main(String[] args)

How can I get android to "navigate" through links on website? Say the first activity in my app allows the user to input their username and password, which would then be stored into Strings. Then the app would "enter" the strings into the username and password boxes and "click" the login button on the website. This "filling" and "clicking" would be done in the background, while the user sees a loading screen. This is the basic idea. So how would I get the app to "fill" in the username and password boxes and "click" the login button? Also, I do not own the website that I'm logging into. My app

I am trying to create a program that calculates sales tax. I first ask the user what was the total cost of their meal. I then ask them what is the sales tax of their area in the form of: y = input('What is the sales tax of your area? ') I want to have a percent sign "%" at the end of the question so that the users sees the question as: What is the sales tax of your area?_% , where the user can enter a number between the question and the percent sign (denoted by the underline). This is what I have tried: x = float(input("What is the cost of your meal? ")) y = input("What is the sales tax in

I've got a custom view and I want to get the X and Y coordinates of a user click. I've found that I can only get the coordinates from the onTouchEvent and an onClickEvent won't fire if I have an onTouchEvent. Unfortunately the onTouchEventfires when the user drags the screen as well as clicking. I've tried to differentiate between the two, but I still get the code firing when I'm dragging: public boolean onTouchEvent(MotionEvent event) { int action = event.getAction(); if (action == MotionEvent.ACTION_DOWN) { //fires on drag and click I've had a look at this but as I mentioned above I don't

What is the best way to block certain input keys from being used in a TextBox with out blocking special keystrokes such as Ctrl-V/Ctrl-C? For example, only allowing the user to enter a subset of characters or numerics such as A or B or C and nothing else. I would use the keydown-event and use the e.cancel to stop the key if the key is not allowed. If I want to do it on multiple places then I would make a user control that inherits a textbox and then add a property AllowedChars or DisallowedChars that handle it for me. I have a couple of variants laying around that I use for time to time, some
