Re: SERVICE_TABLE_ENTRY - Incorrect character format for the name of the service...?
The issue is the const. Try casting serviceName to LPWSTR when used to initialise the array.
PS. The statement
Code:
LPWSTR serviceName = TEXT("name")
actually has serviceName as type LPCWSTR and not LPWSTR as specified. The reason is that serviceName is initialised as a 'pointer to wchar_t' with a string literal - which is a const - c++ now treats initialisation of a 'pointer to' with a const literal as a type const. Hence const wchar_t* and not wchar_t* as written.
Then you are trying to pass a type const wchar_t* to wchar_t* - which breaks the constness and hence the error message and hence the need to cast away the constness.
The underlying issue here is that SERVICE_TABLE_ENTRY (for unicode) for element lpServiceName is type LPWSTR instead of the more correct LPCWSTR.
Victor's suggestion in post #3 uses an array TCHAR (wchar_t for unicode) into which the const string is copied - so in this case serviceName is of type LPWSTR (wchar_t*) and no casting is now required when used with SERVICE_TABLE_ENTRY.
