there are many ways to do this. 1) use a function like this function DisableKeys() { var ar = new Array(122 , 123); $(document).keydown(function(e) { var key = e.which; if ($.inArray(key, ar) > -1) { e.preventDefault(); return false; } return true; }); } 2) example 2 $(document).keydown(function(e){ if(e.which === 122){ return false; if(e.which === 123){ … Read more
You must pass the value belongsId: db.delete(TABLE_NAME, “BELONGS = ‘” + belongsId + “‘”, null); 5 solved how I can delete multiple rows with same id like in android sqlite
The framework fundamentally does not work that way. If you stay true to the framework, you can wrap your button in an update panel. That will remove the visible postback, but that will still fire the postback and perform the page load and click event. In essence the update panel will dump your entire page … Read more
add the following to the imports on your app.module.ts RouterModule.forRoot( [ { path: “”, component: LoginComponent} ] ) solved StaticInjectorError(Platform: core)[RegisterStoreComponent -> Router]: NullInjectorError: No provider for Router! Angular 5.2 / Karma-jasmine
One of the many solutions, given the fuzziness of the question, is to use Core Animation. The official Apple documentation is here. Let’s outline three steps: Conceptual step Define what layers (conceptually) or masks you will use, and create the images that will be imported in them Definition step Define your CABasicAnimation and program the … Read more
Use a List (e.g. ArrayList) instead. And before passing it to the Graph API convert it back to Numbers[] array with toArray(). There’s also an example how to loop over the list in the toArray link. solved Add and retrieve elements with Numbers array in Java
The official source for the Java standard library is the standard Java API documentation. And one notable source for design patterns is the book Design Patterns: Elements of Reusable Object-Oriented Software. To begin with, when you look at the options, the question (as quoted in your post) is badly formulated: “Which of the following classes … Read more
Yes, a windows service would be fine. I’d like to use a little library called TopShelve to make a service / console app. Then I’d add NancyFx to expose the service and it’s data (or read it from a shared database). You also asked if there was a ‘better’ way. You might argue that polling … Read more
The random() function from stdlib.h is actually a POSIX function, not a C one. So it is only guaranteed to be available in POSIX systems, such as Linux. If you want to be portable to other C environments, use rand(). Or if you use C++, as your tag suggest, and a not too old compiler, … Read more
val is initialized to val = x ^ y; i.e. val is the bit-wise XOR of x and y, which means it contains 1 in all the bits where x and y differ and 0 in all the bits where x and y are the same. Now, each iteration of the loop performs val &= … Read more
My answer follows the DRY Principle (Don’t Repeat Yourself). If you put the function in both files, and later find a bug on Page #1, someone has to remember that the function is duplicated on Page #2 as well (in this case, assume the bug report says “Page #1 doesn’t work properly”). From that bug … Read more
You can format it with commas, and replace the commas with spaces var result = inputNumber.ToString(“N0”,CultureInfo.InvariantCulture).Replace(‘,’, ‘ ‘); 4 solved Number formating spaces every 3 digits
I don’t think the run() and pause() strategy is the way to go because the DispatchQueue API is not designed for realtime accuracy. Which means there will be no guarantee that the pause will be 16ms every time. On top of that, restarting a session might not be immediate and could add more delay. Also, … Read more
In this case, another alternative to consider would be: Id = (blah == null || something.x) ? null : something.y; The benefit being that only one ternary is necessary (and thus null is returned from only one “branch” out of two, rather than two out of three). solved Code smell Id = blah== null ? … Read more
You must use Collections.sort() method and pass the list as argument. The list will be ordered according to the natural ordering of its element. You can have more info here: http://docs.oracle.com/javase/7/docs/api/java/util/Collections.html solved Sort the arraylist with date, which is in string format [duplicate]
