thanks a lot

~~It should be in double-quote marks ("centroids.h").~~

You should also add the file(s) into the project.

How did you insert header file to your project?

i inserted header file in solution explorer, right click header files tap..and then choose add item..then choose .h file..i think this is no problem, it is right?

1) Can you list the path of project, and the path of that file?
Example:
Project is at C:\Tmp\MyTest
Header file is at C:\Include\myheader.h

2) Any special characters in the path?

What file is centroids.h being referenced from? Is this header file in a path that the IDE knows about? Have you tried using a fully-qualified path in the #include statement, like:

#include "c:/program files/microsoft visual studio/.../centroids.h"

Define UNICODE in the preprocessor definitions of project settings to make it support Unicode.

First of all, make sure the appropriate language is installed on your machine. Next to it, make sure that you are making an Unicode build and not an ANSI build. Remove the _MBCS preprocessor directive and add the preprocessor directive:

#define _UNICODE //with the underscore.

This will implicitly add the preprocessor directive:

#define UNICODE //no underscore. (this is for windows api functions)

So, the compiler will make wide calls for both CRT functions and windows api functions and your application will be able to understand Unicode.

Yes, I've read that years ago. If I remember it right, Jeffery Ritcher's book has a very detailed explanation of this very interesting stuff. Smile | :)

Overwrite avoiding in memcpy

Hi all,

First I create a dynamic buffer and set all element to zero. Then add a int value first to the buffer. Then after that int value add a string to the buffer, actually at the end of int value. But seems my code overwrite each other.

Here is the code,

char* tmpBuffer = new char[10];// Dynamic allocation
::memset(tmpBuffer, 0, 10);

::memcpy(tmpBuffer, &iReq, 4);
::memcpy(tmpBuffer, &strGetName, 6);

How can I avoid this.

I appreciate your help all the time...

memcpy(&tmpBuffer[4], &strGetName, 6);

You mean like this,

::memcpy(&tmpBuffer[0], &iReq, 4);
::memcpy(&tmpBuffer[4], &strGetName, 6);

Great.........

a good idea would be to use sizeof, ie:

::memcpy(&tmpBuffer[0], &iReq, 4);<br />
::memcpy(&tmpBuffer[sizeof(int)], &strGetName, 6);

Refined as below:

memcpy(&tmpBuffer[0], &iReq, sizeof(int) );
memcpy(&tmpBuffer[0 + sizeof(int)], &strGetname, 6);

Even more: Big Grin | :-D

char* tmpBuffer = new char[sizeof(iReq) + strlen(strGetName)];
memcpy(&tmpBuffer[0], &iReq, sizeof(iReq) );
memcpy(&tmpBuffer[0 + sizeof(iReq)], &strGetName, strlen(strGetName) );

still, it's not the state of art Wink | ;)

char* tmpBuffer = new char[sizeof(iReq) + strlen(strGetName)];
if (tmpBuffer)
{
  memcpy(&tmpBuffer[0], &iReq, sizeof(iReq) );
