33. Windows Service - Part-3 - Windows System Programming in C/C++

In This Tutorial, I have covered the 3rd part of video Tutorial.
I have covered following function:
4. void ServiceReportStatus (DWORD dwCurrentState,
DWORD dwWin32ExitCode, DWORD dwWaitHint);
5. void ServiceInit (DWORD dwArgc, LPTSTR *lpArgv );

Hi, there is a problem I can't find a solution for:
E0144 a value of type "const wchar_t *" cannot be used to initialize an entity of type "LPWSTR"

it appears for SERVICE_NAME in the main function, under STEP-1:

SERVICE_TABLE_ENTRY DispatchTable[] =
{
{SERVICE_NAME, (LPSERVICE_MAIN_FUNCTION)ServiceMain},
{ NULL, NULL }
};

I notice that some other of your followers are having the same problem. Could you help us, beginners, solve this, please?

#1 EDIT:
I found what about the problem was. SERVICE_TABLE_ENTRY required LPWSTR definition of which is long pointer string buffer (=expected wchar_t) but I was putting there LPCWSTR (long pointer CONSTANT string buffer). So all I needed is to convert const wchar_t to non-const wchar_t. I made by the following code.
To local variable definition in the main function I added:
//New array which is non-constant. Expecting 10 symbols because of SERVICE_NAME is "ASPService"
wchar_t servicename[9];


/*Thanks to function wcspy I can copy a const wchar_t SERVICE_NAME to the non-constant wchar_t servicename.*/
wcscpy(servicename, SERVICE_NAME);

Then I edited the SERVICE_TABLE_ENTRY argument from:
{SERVICE_NAME, (LPSERVICE_MAIN_FUNCTION)ServiceMain},
to:
{servicename, (LPSERVICE_MAIN_FUNCTION)ServiceMain},

Note: I didn't try this code, just got rid of errors. I am just a beginner and all I wrote in this section may be wrong.
