_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.

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

The lstrcpy function has an undefined behavior if source and destination buffers overlap. Smile | :)

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.

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()); // The index starts from 0 in Combobox
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[^]
