how to convert char array to wchar_t array?

Question

char cmd[40];
driver = FuncGetDrive(driver);
sprintf_s(cmd, \"%c:\\\\test.exe\", driver);

I cannot use cmd in

sei.lpF         


        

Answer 1

From your example using swprintf_s would work

wchar_t wcmd[40];
driver = FuncGetDrive(driver);
swprintf_s(wcmd, "%C:\\test.exe", driver);

Note the C in %C has to be written with uppercase since driver is a normal char and not a wchar_t.
Passing your string to swprintf_s(wcmd,"%S",cmd) should also work
