14.09.1999 - SvCom 3.0b released

SvCom 3.0 beta for Delphi 5 released

07.09.1999 - Tutorial update

One more example added to the SvCom Tutorial

31.07.1999 - SvCom 3.0 released

In brief this version has two main features:

  • It is compatible with Windows 95 and Windows 98
  • Sources of SvCom experts are added to the file set that is send to registered users

In more details:

Windows 95/98 compatibility. Now you can write applications that will work as services on Windows NT and will work as ordinary exe on the Win95/98 machines. In the last case SvCom applications behave
like NT services:

  • they are invisible for user. Of course they can show a window for a user but by default they are invisible
  • they survive logoff
  • they can be started, stopped, paused or continued and all this actions could be performed from the command line or via API
  • several independent services can work in the same process
  • they can be configured to start automatically when system starts. No matter whether user is logged in or not

Now you can use the same version of your SvCom-based application on Windows NT and on Windows 95/98. And finally now you can develop NT services under 95/98 and they will work both on NT and 95/98 systems !

Two modules are added to SvCom to make it compatible with Windows 9x.
I mean SvComSvc.dll and SvComSc.exe. The first one is a library
that emulates Windows NT Service API under 95/98. Interface to this
library is described in SvCom_WinSvc unit. This library is
installed and used on 95/98 systems only. The SvComSc is a small
service controller that allows to start, stop, pause or continue
service from the command line.

Please note that Windows NT security features are not implemented on Windows 9x systems. This features are not available and can not be emulated. As a result SvCom security-related components will not work on Windows 9x systems.

SvCom experts:

  • Sources of SvCom experts were not distributed before due to some serious problems. The thing is that SvCom experts were based on set of components that could not be distributed without serious compatibility problems. I had to do serious changes in the expert's code to distribute it. I've finished this work so now all registered users will receive sources of SvCom experts. Only few lines of code are eliminated from this sources. I mean the code that checks SvCom registration. So starting from this version registered users of SvCom receive the full sources of my product.

Improvements:

  • Application path to UNC path conversion code is updated. In previous versions this code used exception to indicate that UNC path does not exist. This exception was catched internally and was invisible for users. Unfortunately this exception was visible for Delphi debugger and many users ask me about it. This internally used exception created an impression about bugs in SvCom. I've changed this code to clear up this impression. It was not a bug and I would not like to look it like a bug.
  • The ShareProcess flag is ignored now if only one service
    exists in application. If prevents the possible situation
    in which Windows thinks that there are several services
    in application and disables service profile changes.
