  • when is the right time to draw

    - by stupid_idiot
    hi i just finished essential part of my own personal 2d engine in c++ and i'm kinda deciding how to complete the part where it is actually supposed to display everything on the screen, namely when do I call that function which does the job. I don't have much idea of how does the graphic card work, my biggest experience is calling bios graphic services to write some stuff on the screen. Could you give me a hint on this pls? Or maybe some keywords I should try to google?

  • Interpreter more strict

    - by pacopepe
    Hi, Today, i lost a lot of time fixing a stupid error in my code. Very simplified, the problem was this: def f(): return 2 2 == f I forgot to write the parenthesis in the sentence, so I compared a pointer function with a number. Ok, my question: Is there any way to change the interpreter to be more stricted with the code? Show more warnings for example... Thanks ^^

  • How to use __LINE__ in a string

    - by John
    Just using it as a method parameter is fine but what about an easy way to use it in strings? For instance say I have this: 11 void myTest() 12 { 13 if(!testCondition) 14 logError("testcondition failed"); 15 } And I want the output to be: "myTest line 14: testcondition failed" How can I write logError? Does it have to be some monstrosity of a macro?

    Hello, I´m thinking about writing an android app, but have no experience in programming such apps. My question is whether it is possible to access the standart message editor of android with my app and add for example additional information to it or would it be neccesary to write a complete new editor which would be started as a seperate app. greetings

  • Obtaining standard port for arbitrary protocols in PHP

    - by Trott
    I'm looking for a function that will accept a string representing the scheme portion of a URL (e.g., "http", "https", "ftp", etc.) and return the standard port. It might be used like this: echo get_port_from_protocol("http"); // 80 As a last resort, I suppose I could write something to parse through /etc/services (assuming I only need to run under UNIX-like operating systems). But surely there must be something built-in to PHP, no?

  • Javascript Date: Ensure getMinutes(), getHours(), getSeconds() puts 0 in front if necessary

    - by Mega Matt
    Hi all, Looking for a creative way to be sure values that come from the getHours, getMinutes, and getSeconds() method for the javascript Date object return "06" instead of 6 (for example). Are there any parameters that I don't know about? Obviously I could write a function that does it by checking the length and prepending a "0" if need be, but I thought there might be something more streamlined than that. Thanks.

  • Change query to use a LEFT join

    - by Craig
    I have a query which is failing, as it needs to be using LEFT JOIN, as opposed to the default INNER JOIN used by the 'join' syntax: var users = (from u in this._context.Users join p in this._context.Profiles on u.ProfileID equals p.ID join vw in this._context.vw_Contacts on u.ContactID equals vw.ID orderby u.Code select new { ID = u.ID, profileId = p.ID, u.ContactID, u.Code, u.UserName, vw.FileAs, p.Name, u.LastLogout, u.Inactive, u.Disabled }).ToList(); How would i re-write this so that is utilises a LEFT join?
