i'm trying change text of class label class. have class mainwindow, contains label. i have bot class wanna change value of label. i'm trying create signal , slots have no idea start. i created signal , slots so: //in mainwindow.h signals: void changetextsignal(); private slots: void changetext(); //in mainwindow.cpp void mainwindow::changetext(){ this->label->settext("foobar"); } but have no idea how connect signal able change label's text class. read on qt signal-slot mechanism . if understand correctly, trying signal bot mainwindow label text needs change. here's how it... //bot.h class bot { q_object; //other stuff here signals: void textchanged(qstring); public: void somefunctionthatchangestext(const qstring& newtext) { emit textchanged(newtext); } } //mainwindow.cpp mainwindow::mainwindow { //do other stuff this->label = new qlabel("original text"); mybot = new

this xml code have before attempt adjust scrollable: <?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <!-- widgets --> </relativelayout> how edit make scrollable? dragging on scrollview widget list messes up. make sure leave version/encoding line @ top of file. change relativelayout scrollview , nest relativelayout section (containing of widgets) inside new scrollview . make sure give relativelayout dimensions, should same scrollview width , height dimensions. the reason nesting of relativelayout contains widgets scrollview element can have 1 child element (in case, relativelayout , has own children). therefore code: <?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="

i trying develop computer game. want game multiplayer playable. game arcade space shooter i plan run game @ server level , send updates @ clients. problem facing object creation. let's if player shots, shots new objects. these need created. in game have hierarchical structure , shots part of structure. tree. problem have identifying objects on clients , server. how can make sure when client receives update update right objects? what new object creation. in case scene graph traversed , each object updated once gets updates server. updates creates new object violates principle. how should handle them? also, can't updates entire scene. need update specific objects visible player. should rest of objects aren't visible? happen when become visible? how can track when objects become visible player? how can make sure when client receives update update right objects? you can give unique id each object server creates. might want create super object cl

reading question: delphi windows service design , saw designer use code below in onexecute of tservice or in tthread method, in order keep service alive. while not terminated begin // end; but if need (and do) create service respond (using indy) messages sent main application in order send authentication data, do code, ignore or put sleep() in it? indy's tidtcpserver , tidudpserver components multi-threaded, don't need use tservice.onexecute event @ all. activate them in tservice.onstart event , deactivate them in tservice.onstop event, , assign handlers tidtcpserver.onexecute , tidudpserver.onudpread events needed. both events looped you, don't need while not terminated loop in them. read/process 1 request needed, exit, , wait next event repeat. let server handle exceptions raised. , keep in mind tidudpserver has threadedevent property false default, should set true inside service.

given several tables, best way take poll of row counts in tables clauses included? i'd @ once can inserted table daily record of row counts. tablea - count of rows fit condition 1, specific column value x select count(*) tablea col1 = x tablea - count of rows fit condition 2, specific column value y select count(*) tablea col2 = y these 2 combined into: select (select count(*) tablea col1 = x) 'x count', (select count(*) tablea col2 = y) 'y count' but i'd add in: tableb - count of rows created within last specified interval select count(*) tableb datecreated >= date_sub(curdate(), interval 1 day) col3 = z; this gives me: select (select count(*) tablea col1 = x) 'x count', (select count(*) tablea col2 = y) 'y count', (select count(*) tableb datecreated >= date_sub(curdate(), interval 1 day)) 'z count'; it seems run though, there more efficient way of counting rows in case? your query looks fine,

i know has been asked many times before none of solutions seem work in situation. i need checkbox on each row disable next text field. each table row created on fly (js clone). first row static. each subsequent row, name , id appended new number (formfield1, formfield2, etc) , happen after page has loaded. html <div class="add_rec_container" id="fuel_stop" style="display:block;"><!--open #fuel_stop--> <p class="label">enter fuel stop:</p> <table width="100%" border="0" cellspacing="0" cellpadding="0" id="fuel_stop_table" class="fuel_data"> <tbody> <tr> <td><select name="data_fuel_state1" id="data_fuel_state1" class="state_menu"> <option value="az">az</option> <option value="ca" selected="selecte

i trying understand maybe monad of examples saw used language-specific feature. ensure have gotten conceptually right thought of writing generic implementation. below came with. can tell if have gotten conceptually right? there better way generalize it? def f(): return 2 def g(): return 4 def h(): return 7 def i(): return none def bind(val, func): if val none: return none else: return(func()) unit = 0 >>> bind(bind(bind(unit,f),i),h) #returns nothing >>> bind(bind(bind(unit,f),g),h) #returns value >>>7 what if wanted add values these functions , abort if of null; suggestion? you're close, signature of bind is m -> (a -> m b) -> m b so it's "unwrapping" m , passing contained value next function. have m -> ( () -> m b) -> m b since you're ignoring val bind gets, should have def bind(val, func): if val none: return none else:

step 1 : create inhered control class public class test_control inherits listbox public sub new() items.add("test") end sub end class step 2 : drag class form in designer step 3 : run project result : why happening?! stumped here.. have googled , googled , cannot find solution or answer this. this causing major issues me. trying add initial "select one..." option every newly created combobox. same thing happens every inherited control class, regardless of control type (textbox/combobox/listbox/etc). same thing happens if use message box within new(). 2 message boxes appear run application. you need tell designer not serialize items collection: public class test_control inherits listbox public sub new() items.add("test") end sub <designerserializationvisibility(designerserializationvisibility.hidden)> _ public shadows readonly property items listbox.objectcollection

as question states looking create struct in c total size not know @ compile time. for example, create struct contains count value , array count elements. know implemented as: typedef struct mystruct{ int count; int *myarray; } mystruct; however, want struct take 1 solid block of memory use memcpy() on @ later point in time. this: typedef struct mystruct{ int count; int myarray[count]; } mystruct; it sounds you're looking flexible array members: typedef struct mystruct { int count; int myarray[]; } mystruct; then, when allocate later: mystruct *x = malloc(sizeof(mystruct) + n * sizeof(int)); x->count = n;

in student table query create default constraint on column address value should updated automatically based on data of city+''+street+''+houseno. well if column based on values in other columns not create new column @ redundant. construct value when query table. you virtual columns means ensuring definition of constructed value consistent , indexed, however. http://docs.oracle.com/cd/b28359_01/server.111/b28279/chapter1.htm#featureno07254

i trying make impossible operator overloading. particularly interested in overloading assignment operator, receive another data type value right hand value. should this: myclass myclass = "hello world"; <--- wrong? myclass myclass2; myclass myclass = myclass2; <--- right? then myclass object should receive string , handle it. unfortunately, read possible assign same data type value custom made class. true or mistaken? this code have: class myclass { public: myclass() {}; virtual ~myclass(); myclass& operator = (const myclass&); private: char* string; }; myclass& myclass::operator= (const myclass& inc){ string = inc; } int main(int argc, char** argv) { myclass myclass = "hello world"; std::cout << myclass; } as can see, want cout object string. basically, want custom class treated string. search in google , stackoverflow search engines denied wish, or there workaround? looking f
