  • Why does this basic class not work?

    - by kalaba2003
    I could not understand why my class does no t work. Returns nothing. Is there any mistake? class User { public $first_name; public $last_name; public function full_name() { if(isset($this->first_name) && isset($this->last_name)) { return $this->first_name . " " . $this->last_name; } else { return "No name!"; } } public function assign () { $this->first_name = "Name"; $this->last_name = "Surname"; } } $user = new User(); $user->assign(); $user->full_name(); ?>

  • Can typeid() be used to pass a function?

    - by Kerb_z
    I tried this and got the output as: void Please explain the following Code: #include <cstdio> #include <typeinfo> using namespace std ; void foo() { } int main(void) { printf("%s", typeid(foo()).name());// Please notice this line, is it same as typeid( ).name() ? return 0; } AFAIK: The typeid operator allows the type of an object to be determined at run time. So, does this sample code tell us that a function that returns void is of *type void*. I mean a function is a method and has no type. Correct?

  • convert char[] to String in btrace

    - by usovmv
    Hi folks! I'm profiling application with btrace (https://btrace.dev.java.net) and faced with limitation. I try to get a name of current java.lang.Thread. Normaly you can call getName() but it's forbidden in btrace-scripts (any calls exception BTraceUtils). Is there any idea how to get String from char[]. The original task is check if name of thread contains sub-string and only then log out tracing info (reducing output). thanks, Max.

    I am trying to find if the process is running based on process id. The code is as follows based on one of the post on the forum. I cannot consider process name as there are more than one process running with the same name. def findProcess( processId ): ps= subprocess.Popen("ps -ef | grep "+processId, shell=True, stdout=subprocess.PIPE) output = ps.stdout.read() ps.stdout.close() ps.wait() return output def isProcessRunning( processId): output = findProcess( processId ) if re.search(processId, output) is None: return true else: return False Output : 1111 72312 72311 0 0:00.00 ttys000 0:00.00 /bin/sh -c ps -ef | grep 71676 1111 72314 72312 0 0:00.00 ttys000 0:00.00 grep 71676 It always return true as it can find the process id in the output string.

  • NSMutableArray with NSDictionary to Labels without the surrounding brackets

    - by bigubosu
    I'm making a scoreboard for my game. And when I do a NSLog of the data it comes out as this: { name = TTY; score = "3.366347"; } So my question is how do I remove this brackets and also just grab the name (TTY) and score (3.36 without the quotations) and place them in variable for me to put into labels. Currently I can place them in labels but they have the lingering curly braces "{" and "}". Any hints would be helpful as I'm happy to search further I just don't know the vocab to search for it. thanks

  • What can you do in ::OnInitDialog() Visual Studio 2008 C++

    - by flirishman
    What can or cannot you do in ::OnInitDialog() Visual Studio 2008 C++ I would like to write out some text on the dialog at the dialog startup. If I put the same code in a PUSH-BUTTON OnBnClicked it works. If I put it in the OnInit, it does not give me the text on the screen. I'm assuming at the OnInit, my dialog box is not completely up, so I cannot write on it? CRect drawRect; drawRect.left = 00; // Shifts text to right drawRect.right = 300; drawRect.top = 00; // How Far Down drawRect.bottom = 300; // Clear out any previous name CString strBlank = "Book Name"; SSTextOut(this->GetDC(), strBlank, &drawRect, DT_LEFT); The function I am writing to is described in http://www.codeproject.com/KB/GDI/SSTextOut.aspx

  • Searching strings C

    - by Skittles
    First time posting here so I'm sorry if I mess up. I need to search a string and return any strings containing the search data with the search data highlighted. If my string is Hi my name is and I searched name it would produce Hi my NAME is This is a quick code I wrote that works but it only works once. If I try and search again it seg faults. I was hoping someone could hint me at a better way to write this because this code is disgusting! void search(char * srcStr, int n){ int cnt = 0, pnt,i = 0; char tmpText[500]; char tmpName[500]; char *ptr, *ptr2, *ptrLast; int num; while(*(node->text+cnt) != '\0'){ //finds length of string cnt++; } for(pnt = 0; pnt < cnt; pnt++){ //copies node->text into a tmp string tmpText[pnt] = *(node->text+pnt); } tmpText[pnt+1] = '\0'; //prints up to first occurrence of srcStr ptr = strcasestr(tmpText, srcStr); for(num = 0; num < ptr-tmpText; num++){ printf("%c",tmpText[num]); } //prints first occurrence of srcStr in capitals for(num = 0; num < n; num++){ printf("%c",toupper(tmpText[ptr-tmpText+num])); } ptr2 = strcasestr((ptr+n),srcStr); for(num = (ptr-tmpText+n); num < (ptr2-tmpText); num++){ printf("%c",tmpText[num]); } while((ptr = strcasestr((ptr+n), srcStr)) != NULL){ ptr2 = strcasestr((ptr+n),srcStr); for(num = (ptr-tmpText+n); num < (ptr2-tmpText); num++){ printf("%c",tmpText[num]); } for(num = 0; num < n; num++){ printf("%c",toupper(tmpText[ptr-tmpText+num])); } ptrLast = ptr; } //prints remaining string after last occurrence for(num = (ptrLast-tmpText+n); num < cnt; num++){ printf("%c",tmpText[num]); } }

  • MySQL: Select remaining rows

    - by Bjork24
    I've searched everywhere for this, but I can't seem to find a solution. Perhaps I'm using the wrong terms. Either way, I'm turning to good ol' trusty S.O. to help my find the answer. I have two tables, we'll call them 'tools' and 'installs' tools = id, name, version installs = id, tool_id, user_id The 'tools' table records available tools, which are then installed by a user and recorded in the 'installs' table. Selecting the installed tools are simple enough: SELECT tools.name FROM tools LEFT JOIN installs ON tools.id = installs.tool_id WHERE user_id = 99 ; How do I select the remaining tools -- the ones that have yet to be installed by user #99? I'm sorry if this is painfully obvious, but I just can't seem to figure it out! Thanks for the help!

  • Vim: `cd` to path stored in variable

    - by tsyu80
    I'm pretty new to vim, and I'm having a hard time understanding some subtleties with vim scripting. Specifically, I'm having trouble working with commands that expect an unquoted-string (is there a name for this?). For example cd some/unquoted/string/path The problem is that I'd like to pass a variable, but calling let pathname = 'some/path' cd pathname will try to change the current directory to 'pathname' instead of 'some/path'. One way around this is to use let cmd = 'cd ' . pathname execute cmd but this seems a bit roundabout. This StackOverflow question actually uses cd with a variable, but it doesn't work on my system ("a:path" is treated as the path as described above). I'm using cd as a specific example, but this behavior isn't unique to cd; for example, the edit command also behaves this way. (Is there a name for this type of command?)

  • Get rid the slash in URL (ex. something.com/dogs)

    - by jbenes
    I recently purchased the domain name simply.do. I want to use it as a URL shortening service, but I don't like have to do simply.do/something. Can I remove the slash or replace it with a difference symbol? If this helps, I am using a server running Nginx and I will not switch to Apache. Thanks! I would also appreciate any feedback on the domain name. I was hoping to sell simply.do/insurance, simply.do/religion, etc. to various companies. Do you think there is a way I could sell these parts on an auction website? Thanks!
