[ad_1] You can use OpenGL ES 2.0 on device that support it, older models of the iPhone (orginal and 3G) and iPod Touch ( 1g and 2g) do not support OpenGL ES 2.0. OpenGL ES 1.1 is available on all devices. [ad_2] solved Apple Inc. using OpenGL ES [closed]
[ad_1] An easy way to do this is to read the complete file in as a string with file_get_contents(), split it up on whitespace, and run the resulting array through array_count_values() $file = file_get_contents( ‘text_file.txt’); $array = preg_split( ‘/\s+/’, $file); $counts = array_count_values( $array); Done! However, this isn’t perfect, as punctuation can mess up your … Read more
[ad_1] I think this is everything that every Java class has: A class name. A class access … implicitly package private, if you don’t specify one. A package … implicitly the default package, if you don’t specify one. A superclass … implicitly java.lang.Object, if you don’t specify one. A body which may be empty. A … Read more
[ad_1] This is an algorithm which uses Lapace expansions, which recursively computes the determinant of an n x n matrix by computing n determinants of (n-1) x (n-1) subminors. The determinant of the 2 x 2 matrix should be obvious. There are better ways to do that, like LU decomposition. 1 [ad_2] solved Understanding of … Read more
[ad_1] Static properties belong to the Class whereas instance variables belong to the particular object instance. You should take a read through this: https://docs.oracle.com/javase/tutorial/java/javaOO/classvars.html [ad_2] solved Cannot understand the difference between static and non-static variables in Java. Can anyone help please? [duplicate]
[ad_1] Your code to create dynamic input tags is not correct. Replace <?php echo ‘<input name=”; echo “mycol’.$c; echo ‘id=’; echo ‘mycol’.$c.’ />’ ?> With <?php echo ‘<input name=”mycol’.$c.'” id=”mycol’.$c.'” />’ ?> or <input name=”<?php echo ‘mycol’.$c?>” id=”<?php echo ‘mycol’.$c?>” /> 1 [ad_2] solved Dynamically created is not posting data [closed]
[ad_1] They are different things. Raspberry PI is a computer, arduino is just a microcontroller with peripherals as facilities. Raspberry runs an Operational System inside, Arduino doesn’t. Raspberry has a digital-only set of electrical interfaces. Arduino has both analog and digital. Depend on the project needs one or other is more suitable. Since IoT have … Read more
[ad_1] Just use a for loop to iterate over values of x: for (x = 9; x > 0; x–) { for (y = 0; y < 9; y++) { if (3 * pow (x, 2) + 4* pow(y, 2) == 271) { cout << “x: ” << x << endl << “y: ” << … Read more
[ad_1] To unwrap do as follow let strRating = “\(self.newRateSyting!)\(rateValue!)\(self.ratingTexts[Int(rateValue)]!)” self.rateLabel?.text = strRating Example let value : String? = “4.7” let review : String? = “very good” let strRate = “\(value), \(review)” print(“Before unwrap”) print(strRate) print(“\n After unwrap”) let strRate2 = “\(value!), \(review!)” print(strRate2) Output: Note: If you have array of dict , array of … Read more
[ad_1] What is the most efficient way of replacing duplicate elements in a list B with unique elements from another list(list A) in Qt or C++? [ad_2] solved What is the most efficient way of replacing duplicate elements in a list B with unique elements from another list(list A) in Qt or C++?
[ad_1] NOTE: Your question is not clear. You have not included any code or query snippet. I will try my best to answer your question. As per my knowledge I think your users are nothing but the members. Just write a query to pull all the users from the users table and display. NOTE : … Read more
[ad_1] This will do what you think you want, but it’s totally NOT recommended. Templates (or std::swap) really are the right answer here. First, define an inline function to take void ** inline void SWAP_POINTERS2(void** p1,void** p2) { void* temp = *p1; *p1 = *p2; *p2 = temp; } Then, define a macro to perform … Read more
[ad_1] Sure you can: string directory = @”C:\”; List<string> textFiles = System.IO.Directory.GetFiles(directory, “*.txt”).ToList(); // You can now you textFiles as a DataSource for your List Control you can add using System.IO directive and remove it from the above code; 1 [ad_2] solved C# – Display Files in a Folder on Button Click [closed]
[ad_1] If you want to convert this to the method syntax version, you can do this step by step. I like to start at the end and work through to the beginning: select to Select defines the source: .Select(g => g.OrderByDescending(s => s.MeasureDate).FirstOrDefault()); group is GroupBy: .GroupBy(s => s.SensorUnitId) .Select(g => g.OrderByDescending(s => s.MeasureDate).FirstOrDefault()); from … Read more
[ad_1] Returning a pointer isn’t a problem as long as it points to memory that is still in scope, such as dynamically allocated memory, global data, or local variables that still exist further up the call stack. The problem with the above code is that you’re dereferencing a pointer without assigning anything to it. This: … Read more
