It's an ODBC function: SQLConnect ( SQLHDBC ConnectionHandle, /* hdbc */ SQLCHAR *ServerName, /* szDSN */ SQLSMALLINT ServerNameLength, /* cbDSN */ SQLCHAR *UserName, /* szUID */ SQLSMALLINT UserNameLength, /* cbUID */ SQLCHAR *Authentication, /* szAuthStr */ SQLSMALLINT AuthenticationLength);
I'm needing to turn the server name that is a string object into a char* to cast it to SQLCHAR* and I didn't find any other function that takes const SQLCHAR* instead of SQLCHAR*. Thanks again ; ) . On 1/25/07, Pete Robbins <[EMAIL PROTECTED]> wrote:
OK. I have to ask.... what function are you calling that takes a char*? Is there an equivalent that takes const char*?
