[ad_1] You could do something like this : let str = “_h Hello _h _h World _h” let range = NSRange(str.startIndex…, in: str) let regex = try! NSRegularExpression(pattern: “(?<=_h).+?(?=_h)”) let matches = regex.matches(in: str, range: range) let results: [String] = matches.compactMap { match in let subStr = String(str[Range(match.range, in: str)!]).trimmingCharacters(in: .whitespacesAndNewlines) return subStr.isEmpty ? nil … Read more
[ad_1] I would suggest a simplified “architecture”. Your functions to get the user and computer choices should return values that can be compared. import random CHOICES = (‘rock’, ‘paper’, ‘scissors’) def get_user_choice(): choice = input(‘Rock, paper, or scissors? ‘) choice = choice.lower().strip() if choice not in CHOICES: print(‘Please select one of rock, paper, or scissors’) … Read more
[ad_1] Here what’s happening is when you call Base b = new Derived() it first calls Derived() on derived class. Now as Derived class extends Base class every constructor of Derived class internally calls the default cunstructor of base class, similer to Derived() { super(); addValue(); } which in turns calls the Base(). Now inside … Read more
[ad_1] No that’s not really a good way. If you just want the numbers a numbers, i.e. as normal int values, then use the “%d” conversion operator instead, and have your variables be normal int variables, which you then pass to sscanf using the address-of operator &. As in int num1; int num2; int num3; … Read more
[ad_1] The first problem is that you don’t store the created picker view instance. You instantiate it inside of a function, assign the delegate and dataSource and then you don’t store it in your class. So the ARC (Automatic Reference Counting) releases it, because it thinks the instance is not longer needed. Just create a … Read more
[ad_1] An quick fix, using the previous numerically ordered array, could have been: // Save the keys $keys = array_shift($data); /* here, do the sorting … */ // Then apply the keys to your ordered array $data = array_map(function ($item) { global $keys; return array_combine($keys, $item); }, $data); But let’s update my previous function: function … Read more
[ad_1] What a pity you didn’t write the classes! You seem to have an IQueryable sequence of ta_kegiatan_renja objects, and you assume that every ta_kegiatan_renja object has a property Kd_Urusan. The error says that a ta_kegiatan_renja doesn’t have such a property. The requirement you wrote has nothing to do with the code that you gave … Read more
[ad_1] You can use Timer to periodically update the database Timer timer = new Timer(); timer.Tick += new EventHandler(timer_Tick); // Everytime timer ticks, timer_Tick will be called timer.Interval = (10) * (1); // Timer will tick evert 10 seconds timer.Enabled = true; // Enable the timer timer.Start(); void timer_Tick(object sender, EventArgs e) { //Put your … Read more

[ad_1] The problem has nothing to do with the VAO, but with the VBO. Since you pass a pointer to the constructor: void GSMesh::build(GLfloat *arrFVertex, GSShader *shader, int _intNumVertex) { glBufferData(GL_ARRAY_BUFFER, sizeof(arrFVertex), arrFVertex, GL_STATIC_DRAW); } sizeof(arrFVertex) = sizeof(GLfloat*) which is the size of the pointer, not the size of the array pointed to.
