Non-static method (method name()) cannot be referenced from a static context. Why?

不打扰是莪最后的温柔 提交于 2019-12-01 12:19:49
I'm really confused with this! I have 2 classes, Club and Membership . In Membership I have the method, getMonth() , and in Club I have joinedMonth() which takes the parameter, 'month' - so a user enters a month and then I want it to return the Membership's which joined in that specific month. I am trying to call the getMonth() method from class Club, so that I can then go on to compare the integers of the months. But, when I try to call the method, I just get the mentioned "non-static method getMonth() cannot be referenced from a static context". Basically, what is this and how can I resolve

Receive varying variable inputs from PHP into c++

一个人想着一个人 提交于 2019-12-01 10:58:26
I have a program that needs to be sent the following variables: Bool int string vector<int> vector<string> This will come from a PHP call as I've looked into here and here . Looking at this question about (int argc, char** argv[]) , I know that you can pass various arguments to a program that it needs so to run, but these are all in the form of a Character Sequence . So my question is: If it is possible, how do you go about sending across multiple varying variables in a PHP call to a C++ program? EDIT (Question continued) ...and what would the function call look like? Is it as simple as not

Call Activity Method From Fragment

核能气质少年 提交于 2019-12-01 09:12:42
I'm dealing with fragments. I have an Activity and different fragments . Each fragment need the access to a Class(call it X) that allow it to access a database, but, because I have a lot of fragments, I don't want to create a different instance of the Class X in every fragment as I think it will require lots of memory . So how can I do? I wrote something like this (with a getter), but it doesn't work! public class MyActivity { private ClassX classx; ..... public ClassX getClassX() { return classx; } ..... } But than, how can I call it from the fragment ? This is a little bit more of a Java

Difference between call and cmd /c in windows batch

↘锁芯ラ 提交于 2019-12-01 06:25:55
Can someone please explain what's the difference between call someBatchFile.bat ... And cmd /C someBatchFile.bat ... They both were suggested to me as solutions to this problem, but I don't understand why they both work, and more importantly, if there are any significant differences I must be aware of. The difference is that call execute the other Batch file in the same context of the caller program, so they share the same environment variables and other status (like echo ON/OFF or delayed expansion), whereas cmd /C execute the other Batch file in an entirely separated context, so any change

Calling a function from a different view controller for iphone

不问归期 提交于 2019-12-01 05:35:28
I have a problem where I want to call a function defined in one view controller from another controller. I'v try what seems llke a hundred different setups and nothing seems to work. I've posted the basic code and was hoping someone could tell me how they would do it. Basically all I want to do is call the MYBPress function defined in the SwitchViewController from the GameViewController when the dealB button is pressed. Any help would be greatly appreciated. PS: I have coded for a long time, but am realtivly new to Obj-C // ------- SwitchViewController.h --------------- #import <UIKit/UIKit.h>

Making redundant OpenGL calls

白昼怎懂夜的黑 提交于 2019-12-01 04:38:24
I was wondering if it is recommended to eliminate all redundant opengl calls. For instance, should I be doing something like (wrapped in a function): if(foobuffer != boundbuffer) { glBindBuffer(GL_BAR_BUFFER, foobuffer); boundbuffer = foobuffer; } Or is the driver automatically doing such things and this is actually a redundant reduntant-check? You should probably avoid it. Here (specifically 22.040, you'll have to scroll down the page since there's no anchor for it), it is noted that redundant calls are generally bad practice even though some implementations attempt to minimize the impact.
