Question

hello all
i have code from open source project that im integrating into my code .
now my code settings in visual studio 2008 character set is Unicode . and the external code is
Multi-Byte Character Set. when i change the character setting in my application after adding the new source
im getting other errors in my code .
so reading from the net i guess i need to make some changes to the external code to support unicode.
here is my code :

string FullPathToExe = c:\\foo\\boo.exe;
vector<char> str2(FullPathToExe.begin(), FullPathToExe.end());
    str2.push_back('\0');
    if (!CreateProcess(NULL,
                     &str2[0],
                    NULL,
                    NULL,
                    TRUE,
                    0,
                    NULL,
                    NULL,
                    &si,
                    &pi))
and the error is :
 : error C2664: 'CreateProcessW' : cannot convert parameter 2 from 'char *__w64 ' 
 to 'LPWSTR'

im not win32 programmer and this is new to me.

how can i support both developer that are using multi byte and Unicode ?

Thanks for helping

For the first one use vector<wchar_t> instead of vector<char>.
For the second one use L"ERROR: API = %s.\n error code = %d.\n message = %s.\n" instead of "ERROR: API = %s.\n error code = %d.\n message = %s.\n" (note the L at the start.
