Web Service as Windows Service

Posted: Oct 26, 2017 3:38 AM

Hi All,

I try to create a web service as Windows service. Base class is inherited from TService.

class MyService : public TService
{
  . . .
}

However there is ambiguity between Soap::Wsdlbind::TService and Vcl::Svcmgr::TService. When I define class inheritance as below

class MyService : public Vcl::Svcmgr::TService
{
__published:
  void __fastcall ServiceStart(TService *Sender, bool &Started);
  void __fastcall ServiceStop(TService *Sender, bool &Stopped);
  . . .
}

Then ServiceStart and ServiceStop has ambiguity between Soap::Wsdlbind::TService and Vcl::Svcmgr::TService. How to solve this?

Thanks!
Hannu

If you fully qualify the base class like that, then there is no
ambiguity.

void __fastcall ServiceStart(TService *Sender, bool &Started);
void __fastcall ServiceStop(TService *Sender, bool &Stopped);

You need to fully qualify those as well:

void __fastcall ServiceStart(Vcl::Svcmgr::TService *Sender, bool
&Started);
void __fastcall ServiceStop(Vcl::Svcmgr::TService *Sender, bool
&Stopped);

How to solve this?

Either fully qualify the class name, or don't use Soap::Wsdlbind and
Vcl::Svcmgr in the same unit.

Hi

Thank you for your answer. Now I can compile the code without error. However it shows an error "Error in module ServiceMain: Declaration of class MyService is missing or incorrect." when I try to modify and save the code.
