Answer 1

See these notes: Unraveling Strings in Visual C++. The notes discuss the various kinds of strings you'll see in Microsoft C++ development and how to convert between them.

Answer 2

MultiByteToWideChar is the only way to go, if your code is compiled with UNICODE.

Alternatively you can do this. 7bits ASCII -> wchar should be easy.

TCHAR str3[256] = { 0 };
for (int i = 0; str2[i] != 0; i++) str3[i] = str2[i];

Answer 3

LPCTSTR can be either plain char or wide characters depending on your project settings. Further, you cannot possibly concatenate a wide string and a plain char string. You need to convert one to a compatible form (wide to multibyte or vice versa) and then concatenate.

Assuming you want the target to be a wide string, you'd need to convert the "Kumar" to a wide character string. To do this use the MultiByteToWideChar function with appropriate code page.

Look up this KB article on MSDN and John's link.

I tried this it worked:

#include <iostream>
#include <atlstr.h>

using namespace std;
int main()
{
    LPCSTR stringToConvert = "My troublesome string";
    CString transitionString = stringToConvert;
    LPCTSTR myDesiredString = transitionString;

    wcout  << myDesiredString;
}
