Hi guys how to disable the function of "ctrl alt delete"

I'll start off differently by showing what I know how to do: valarray<float> va(100, 0.0f); float* fp; fp = &va; some_c_function( fp, va.size() ); What I want to do though is quite the opposite: float* fp;

Hello The problem i have is this : i want to use the following structure in a DLL that i created: typedef struct _NDIS_802_11_SSID { ULONG SsidLength; UCHAR Ssid ; } NDIS_802_11_SSID, *PNDIS_802_11_SSID;

Perhaps I am misusing template but I want to write a template that creates a class and in the class are three functions, <foo>_set, <foo>_clr, <foo>_tst. So if I invoke the template with a name like 'mask', three methods would be created called mask_set, mask_clr, and mask_tst. In the old CPP world, you could use ## (or was it just #?). I...

Hello, I want to apologise in advance for this being off topic. It's not neither A C nor a C++ question, but to profiling in general, though I my chances are best to find the answer in the C/C++ community. I have a C++ program to profile and went about it by producing large history files of calling dependencies with associated times. It...

If I do this: struct xyz { xyz(); int a,b; } var1; it compiles.

I used following template function: template<class Elem, int Size> int tabSize( Elem (&tab) ) { return Size; } tu deduce size and type of an array passed as parameter, but someone proposed making the argument const (perhaps just out const correctnes), and it become:

Hi, Is there a way to encode/decode HTML using C++?? Thanks, Sarada.

Is there any difference between the following two snippets of code? snippet1: int main() { int* p = new int(5); // With argument for initialising p to the value 5 .... .... ....

class BaseEx { public : virtual void Display() { cout<<"BaseEx:: Display()"<<endl; } }; class DervEx : publjc BaseEx

Hi, all. I'm in Fedora Core 4 .I noticed that a lot of types are defined in stddef.h of Stantard C. I usually include files from /usr/include , but my stddef.h looks like in /usr/lib/gcc/i386-redhat-linux/4.0.0/include/stddef.h. Should I include the file from that path?? I noticed people never include from that path.(Also in many linux...

Hello, I am trying to run a code which compiles fine, but when I try to run it I am facing a series of problems which are quite difficult to understand. I am kind of new with C, the task is then a little challenging. First, the routine where it crashes starts like this void read_instructions(E,argc,argv)

Hello, I have a function that has a static array with two elements in it. When the function is called the first time, it should access element 0, the second time it should access element 1, the third time element 0, the fourth element 1 etc. I can do it by having a static variable holding the index and and if/else-statement but is there a...

Hi, I have a question regarding SGI STL sort implementation: In case of equal elements, will they be output in the same order each time I sort? (I understand that it is not a stable sort, and by "same order" I mean "same order *each time I sort*"). Or is there a random number used in the splitter for qsort? Thanks

Hello, I have a basic question about compilers. What are the different types of compilers, are they written by different companies, why there are different names of compilers, what is the purpose, I want to know about them. Are interpreters of C available, and if yes, how can I get them. Madhura

Hi, all. I feel confuse about below struct definition: typedef struct TAG { comments.... }; What my confusion is: is typedef extra??why we not just use

The current issue of Time has an article on China and Google, and mentions the conflict with their "Don't be evil" motto. This might be an excellent time for letters to the editor pointing out that the Google usenet interface is both evil and destructive, besides making their technology a laughing stock. If a few such letters are published...

Does anyone know what programming language was Novell written in?

I have my source string like this: As i step thru the debugger, I can't understand why namePosStart is 2 namePosEnd is 15 I expect: namePosStart is 9 namePosStart is 11

Hello Everybody, I am looking for a C code that I can use it to get Alpha of a Chi-Square value. Actually I want to give the Chi Squre value and Degree of Freedom (df) and get the alpha value from the program. Thanks, Mohsen

Hi, I am using size_t and ssize_t . But I am confused about them. <ssize_t> typedef int __ssize_t; typedef __ssize_t ssize_t; <size_t > typedef unsigned int size_t;

I have a 2D Array of Integers A. I would like to copy it to another array B taking each row at a time. They are both initialized as pointers to pointers. I would like to use something like the following but it doesn't seem to work for (i=0; i < 3; i++) { while(*A++ = *B++) ; }

What i really wanna do, is defining my own types, it doesnt really matter why. Anyway, i have run into some problems 1) typedef unsigned short U16; U16 test = 0xffffffff; // There should be a limit on this, max value you should be able to asign should be 0xffff // std::cout << test; // result = 0xffff //

What i have is not even a real problem, but i hope someone can help anyway, but first a piece of code_ @code start const unsigned short Size = 2; // 2^N std::bitset<Size*Size*Size> YZ; std::bitset<Size*Size*Size> XZ; std::bitset<Size*Size*Size> XY; std::bitset<Size*Size*Size> V; union {
