blobs are nothing more or less than large chunks of binary data. The database knows nothing about the blob's contents, its up to your program to interpret that.

[QUOTE=Kikazaru;1149127]Thanks for the quick responses. What I'm really wondering is whether giving the const qualifier really does facilitate any compiler optimizations (in the case of a variable which is local to a function and only assigned upon initialization).

It sounds like a math problem not a programming problem (combination theory). How many combinations are there in N values taken two at a time? If there were just 2 points, X and Y, there would be just one line. Given 3 points, X, Y, and Z, there would be …

That link to Turbo C++ Explorer 2006 is incorrect.

>>Will this do the job? Don't know -- why don't you compile and test it to see if it will work correctly. add a print statement on every insertion to see if the array was shifted correctly.

Oh well, win some, lose some. Congratulations to Canada for that win. But we still have more medals than they do.

0 seconds is probably correct. Computers will execute that code in just a few nanoseconds. Call clock() instead of time() because clock() has higher resolution. But that too may result in 0. If it does, then call that Multiply function several hundred times and take the average time. [code] clock_t …

It will depend on what operating system you are using. [URL="http://winprog.org/tutorial/"]This[/URL] is a pretty standard tutorial for MS-Windows.

read the file one word at a time and compare each word read with the string. you can use fstream's extract operator >> to do that [code] std::string word; std::fstream in("filename"); // read one word in >> word; // now compare [/code]

So what do you need help with? We are not going to write that program for you, so you might as well get started.

I'm trying to recall from some work I did 15 years ago. Seem to remember that all you do is xmit a single byte that contains the bit pattern you need. But then again, maybe not. SetCommStat() might do it for you.

See [URL="http://www.daniweb.com/code/snippet216612.html"]this code snippet [/URL]I posted here about 5 years ago.

The comparison function is comparing addresses, not the values that are in the structures [code] int indirectstructsortbyid(const void *i1, const void *i2) { struct mys **a = (struct mys **)i1; struct mys **b = (struct mys **)i2; return (*b)->id - (*a)->id; } [/code] [edit]^^ Adak beat me to it.[/edit]

My guess is that you are including MyClass.ini on two or more *.cpp files. objects can not be declared in header files because it causes the multiple declaration link errors that you have. Suggest you do not use MyClass.ini at all. Instead, put the initialization in one, and only one, …

When line 2 failes that function should return right away instead of processing the rest of that function.

strstr() is used to find a string within another string. For example, it would check if "World" is contained in the string "Hello World". strstr() is not related to structures or typedef struct.

It will depend on the operating system and compiler you are using.

Memory for all types of static variables is allocated when the program is compiled, just the same as when memory is allocated to normal global variables. When your compiler creates the executable program that program includes memory for all the functions that you wrote (or linked with in libraries) as …

The first parameter is a two dimenaional array of characters, declared something like this: [icode]char grid[20][MAX_Y];[/icode]. The second parameter is a single Line object passed by reference. [code] char grid[5][MAX_Y]; Line line; drawLineInGrid(grid,line) [/code] I assume you need to initialize the grid with some values before calling that function.

That's why you should write and debug such programs in small sections. I suppose you are using *nix, so learn to use a debugger such as dbg, which will pinpoint the seg fault for you by using the core file. The program first has to be compiled for debug -- …

You may have physically placed the libraries in those directories, but did you tell your compiler that it needs to look for those libraries ? I don't use Borland compilers so I don't know how to do that. Maybe in project setting somewhere.

I wouldn't make duplicates of A and B, but put the results in matrix C so that A and B are left unchanged.

how did you write the gui? win32 api, MFC, wxWindows or something else? And is the serial port code in the same or different thread than the gui?

The scope operator is c++, not C. In C give the variables different names so that you, and the compiler don't get confused.

combine the loops on lines 31 and 37 because there should only be one loop, not two. [code] while( infile >> lname >> fname >> midInitial ) { file2 = fname + lname + ".dat"; ifstream in(file2.c_str()); if( in.is_open()) { while( in >> ton ) { // do stuff here …

lines 81 and 84. I see no object named "addressbook". There is of course a structure by that name, but no object. Create an object of that type, (don't use the same name as the structure to prevent confusion)

wrong compiler. Use either Code::Blocks or VC++ 2008 Express (both are free) so that the program can take advantage of up to 2 gig RAM and huge data files. The compiler you want to use can't either of those. You will also learn how to write a modern c++ program …

Of course. Since myfile is ofstream it is not necessary to specify ios::out because that's what ofstream does anyway. [code] name += ".sta"; myfile.open(name.c_str()); [/code]

If the reference (e.g. int*& thingy;) was actually allocated somewhere else then your class destructor should not do anything with it. Let whatever created it destroy it.

You sould completly replace cmd.exe with your own version of that program.

reading files is the same in console and gui programs. The difference between C and C++ is that C++ will use fstream and C will use FILE*. There are many tutorials and code snippets that will show you how to read a file using FILE*.

1) include stdlib.h and use _MAX_PATH macro to declare the size of the source and destination buffers. On MS-Windows its value is 260. In c++ programs it will be better to use std::string variables instead of char arrays. If you do that then you don't need stdlib.h. line 21: The …
