 | Well yes. You can pretty much fwrite a file, then ShellExecute it to open it from the disk using it's current associated editor. [CODE] FILE *file = fopen("D:\\myText.txt","w"); fputs(file, "HellO"); fclose(file); ShellExecute(NULL,"open","D:\\myText.txt","","", SW_NORMAL); [/CODE] |
| | Yes you can provided you have your own GSM band or find some service provider which by all means would be more than happy to charge you for it. Still it will be far from being an IRC.  |
| | Re: const pointers lets make it a bit simpler: [CODE] int foo = 5; const int cfoo = 10; const int* p = &foo; //Pointer to constant //Since it's a pointer to a constant, *p = 10 won't work int* const p = &cfoo; //Constant pointer (initialization necessary) //Since it's a constant pointer: … |

| | << (LS) can be seen as a multiplication by 2 >> (RS) can be seen as a division by 2 so a number can be divided in terms of powers of 2 as: [CODE]int Divide ( int intVal, int powerOfTwo ) { if( !powerOfTwo ) return intVal; else return intVal … |

| | Re: invoice Think your logic through first, only then the code will follow. Take this example: I want to buy 3 Power Ranger Action figures for 3 kids: -> 2 want Power Ranger Dino Force (@ $2) -> 1 wants Power Ranger SPD (@ $3) So my bill look like: [CODE]--------------------------------------- 09/19/2010 … |

Restore to previous mode (Text mode) return 1; } [/CODE] This should be sufficient but BGI …  |
| | One way would be to read 8 bytes & push_back the values into the deque. [CODE] double dub; dq.erase(); //drop elements, if any while(!myfileIN.read(&dub,sizeof(double)) dq.push_back(dub); myfileIN.close(); [/CODE] |
| | Well why not create your own function? [CODE] std::string HexToStr(const int value, int width) { std::string hexStr; std::stringstream num; num.width(width); num.fill('0'); num << std::fixed << std::hex << value; hexStr = "0x" + num.str(); return hexStr; }[/CODE] Usage: std::cout << [COLOR="Green"][B]HexToStr(0x0004, 4);[/B][/COLOR] |
| | Consider the following code: [code] const int con = 100; int &ref1 = 10; //Where is this 10 stored? int &ref2 = con; ref1 = 20; ref2 = 90; cout<<ref1<<con<<ref2; [/code] This outputs: 20 100 90 My only queries are: a) Where is the hard coded number 10 stored? b) …  |

| | Basically, I didn't know where to put this so I choose the Super of the 2 Languages. Our lecturer gave us an assignment to lay out diff. b/w C & C++, which started with a rather dirty spurge of concepts. He stated: In C program , the MAIN() should NOT … |
| | One way might be to change the creation order of forms so that Form1 is created last. Then in the initialization code you can assign to a global object the handle value & use it in your form through ShowWindow(). Personally, I include the "Form1.h" into my "Main.cpp" & use … |
| | You shouldn't fret about it. The string will automatically resize depending upon the RAM available until you run out of it, which IMO shouldn't be happening. The common SQL Query might be: [CODE]SELECT <Fields> FROM [Table] WHERE <Condition> GROUP BY <Field> ORDER BY <Field>[/CODE] In the above code the only … |
| | Well you're dealing with integer [URL="http://www.cplusplus.com/doc/tutorial/variables/"]Ranges[/URL]. Apart from that for a specific purpose you can apply the size modifiers (long/unsigned) & even use __int64. |

| | I've recently been programming J2ME apps for Mobiles when it struck to me - something I remembered: "A virus infected my mobile!". I find it strange. Obviously, the regular EXE files don't work on JVM so can no way infect mobile phones. So there should be Java-specific viruses, but J2ME … |
| | Use getline(<istream>,<buff>,<delimiter>). Delimiter will be a ','. |
 | You should try looking into operator overloading: [CODE] int* operator >> (int *RHS) { RHS = this->array; return RHS; //For chaining } [/CODE] |
| | Re: Mouse Movements Well you can use [URL="http://www.google.co.in/search?sourceid=chrome&ie=UTF-8&q=cmsdn+sendinput"]SendInput()[/URL] but it kinda works the same way as mouse_event() so may be considered cheating. |
| | Re: hi ... I don't know what good can come out of this! Still speaking of lionanees's bizarre technique, just put that in a function which call's itself recursively. :-\ Sigh! |
| | [QUOTE]but i want to be the same name in the div function?[/QUOTE] What's stopping you?

| | So basically you need the Arithmetic difference of both arrays, something like this: [CODE] int* getDiff(int *arr1, int *arr2) { int maxCount = 1750; //From your 1st Post int *result = new [maxCount]; for(int i=0 ; i<maxCount ; i++ ) result[i]=arr1[i]-arr2[i]; return result; } [/CODE] |
| | I remember my first test masking program - the good 'ol days with TC(yuck!) & non-standard C++. Yes, jonsca is right & getch() had the key role in it. My code was somewhat like this: [CODE] char pass[50]; int i=0; while(1) { char ch = getch(); if(ch == '\r') { … |

| | A static member does not belong to the object(this), rather, belongs to the class. The following code should make it more clear: [CODE] class foo { public: static int foo1; //Static member int foo2; //Regular member }; int main(int argc, char *argv[]) { foo Obj; Obj.foo2 = 2; //Correct Obj.foo1 … |

| | What exactly is the problem you are facing. 1. Avoid void main(), it's non-standard. 2. Avoid system() calls, since they are worthless & slow 3. Also I recommend you use a class for this. [CODE]class Student { int id; char Answers[20]; }; //Create 50 Objects Student Students[50]; [/CODE] |
