From MSDN:
This function is provided only for compatibility with 16-bit versions of Windows. Applications should use the RegOpenKeyEx[^] function.
Are you programming 16 bit Windows?

WOW, I really need to visit an eye doctor, that did the trick, thank you very much 
|
|

|

Being slightly cynical the function will return FALSE as the only line with return on it is return FALSE;
Cheers,
Ash

why don't you utilize CRegKey class for handlling registry operation!

If RegOpenkey() fails, the return value is a nonzero error code. So what value does hReg have?

The language provides the sizeof operator [^], please use it.

if it string,it would 1 byte per char!
if it int, it would be 4 byte per variable!
Shoot me down, if i am wrong!

ThatsAlok Shoot me down, if i am wrong!
say where and when.
ThatsAlok if it string,it would 1 byte per char!
1 or 2 bytes per character, also counting the terminating null.

C++ string literals (like to one of the OP) have 1 byte per character (wide character string literals must be L prefixed).
They include, as you stated, a terminating 0.

In its simplest (ASCII) form the string "568" will allocate one byte per character and a null byte to signify the end of the string, giving a total of four bytes. If the string uses Unicode encoding then two bytes per character are allocated. If MBCS UTF-8[^] then it may be more than two per character.
An integer will be stored as 16, 32, or 64 bits depending on the type of variable: short, int, long, long long etc.
It's time for a new signature.

Hi,
How to create dynamic single and multiple arrays in C++.
|
|
|
|
|
I would suggest you to use a vector.
vector<int> v1;//single array of integers
vector< <vector<int> > v2;//2-dim array

If you mean dynamically allocated memory then please read the new operator documentation [^].

Hello everyone,
i have a problem,
i want to use FLTK in visual studio 2010. I installt it correctly, I copied the .lib files into the lib folder and the FL folder into the include folder in my Visual studio 2010 directory. My problem is when i compile the folowing code to see if everything works i get these errors:
#include <FL/Fl.H>
#include <FL/Fl_Box.H>
#include <FL/FL_Window.h>
int main()
{
Fl_Window w(200, 200, "title");
Fl_Box b(0, 0, 200, 200, "Hie");
w.show();
return Fl::run();
}

Just copying a library into VC++'s libraries folder doesn't necessarily mean that the linker can automatically link with them (unless the author does some fancy non-portable things - as FLTK is fairly portable I guess they didn't). There are several ways you can get the linker to link with the libs. this[^] article goes over them better than I could.
Cheers,
Ash

I need some code for a template
matrix gauss_jordan(void) { // Gauss-Jordan matrix inversion
assert(this->data[].size() == this->data.size()); // Must be a square
};
I have not seen much of help so far
I do have a code to put a matrix into row echelon form

That is because the message boards are about answering questions and providing guidance for those who are doing the work.
You are asking for someone to do the work for you.
When you have made some progress then by all means ask about specific issues or points.
