_tcscpy and lstrcpy, both implement the same function, which one should I use if I want to copy a string in my project?

_UNICODE is not defined for this.
LPTSTR lstrcpy( LPTSTR lpString1,
LPTSTR lpString2
);
TCHAR is used to represent unicode strings.
So when you are working with unicode you should prefer TCHAR to LPTSTR
_TCHAR * _tcscpy(_TCHAR * to, const _TCHAR * from)
Somethings seem HARD to do, until we know how to do them.

_tcscpy is a CRT function while lstrcpy is a windows native function. It probably does not make a difference which you use, but _tcscpy is probably better for portability reasons.

use C runtime Libarary

IMHO, it better to use Window Based api!

The lstrcpy function has an undefined behavior if source and destination buffers overlap. 
Knock out 't' from can't,
You can if you think you can

So does _tcscpy.

No idea,not used yet.
LPTSTR lstrcpy(LPTSTR lpString1,LPTSTR lpString2);
Using lstrcpy function incorrectly can compromise the security of your application. The first argument, lpString1, must be large enough to hold lpString2 and the closing '\0', otherwise a buffer overrun may occur. Buffer overruns may lead to a denial of service attack against the application if an access violation occurs. In the worst case, a buffer overrun may allow an attacker to inject executable code into your process, especially if lpString1 is a stack-based buffer.
Mostly application getting crashed or Access violations during such behaviour's.

You will have to store the index of the selected item somewhere . Say in a file or a registry, or in a variable in your code if the application keeps on running.
The next time you open your dialog set the item to which the index points to.
Correction::|Here I assumed that you are having a fixed number of items....

How are you proceeding with this.
Did you try and write that index in some file/registry, Where's your logic . Where do you want to store the index for selected item.

i try to write the index in the file after thtai wnat to open it on initdialog.
CFile time;
char Pbuf[2];
time.Write(pbuf,2);

you create a file for a value (number or string)
but its not good idea use file instead file you can write in registry (my suggestion)

where are you opening the file for writing?
CFile file;
file.Open("c:\\abc.txt",CFile::modeCreate | CFile::modeReadWrite );
CString str;
str.Format ("%d",m_combobox.GetCurSel());
file.Write(str,strlen(str));
file.Close();
// This code is not optimized
// Now read the value similarly and use m_combobox.SetCurSel() to set the text in the combo box related to the index

you can use INI file for storing these type of configuration! http://www.codeproject.com/cpp/CIni.asp[^]
