This application is an NT service that make COM objects, written in
any language, behave as a service. The COM objects are created on
separate threads that run in the multi-threaded apartment, so each COM
object can act independently of the both the service and the other
objects. This enables Visual Basic programmers to simply create a COM
object with an embedded timer and have it act as an NT service by
implementing SvcStart, SvcStop, SvcPause, and SvcContinue methods.

This is a library of J++ classes that provide database access, generic
tracing and messaging, and time type conversions.

This class aggregates data from 2 ORACLE databases, and loads it into
a third ORACLE database. It uses ADO to retrieve the data from 2
databases and then combines it into an ADO recordset, which is custom
built by the class. This allows any COM compliant development tool,
such as Visual Basic, to use this object to retrieve data from and
load data into ORACLE databases. Prepared SQL statements that
directly access the ORACLE bind variables are used for high speed
access.

This object provides access to the NT security API's to enable ASP
scripts and other COM compliant containers to determine the SID of the
current user, their full name, and what global and local groups the
user belongs to in any trusted domain.

This JavaScript/JScript is run once a minute as part of a real-time process
data collection system. The script must recover from any error
it encounters so that it will run when the next cycle occurs.
The script features extensive message logging and error reporting.

This object provides access to various NT API's to enable ASP scripts
and other COM compliant containers to use many system services. This
object pushes VB to its limits!

|
This class demonstrates using VB to access an ORACLE database using
high speed prepared queries and generic methods that mimick the MS
Access query syntax to make it easy for developers to select data from
a table using any conditions.

This VBScript manages SQR processes to generate reports as it is
called from a scheduler. The script demonstrates an extensive
message logging and error reporting system as well as creating
synchronous processes from VBScript.
|
|
This library is used by approximately 1000 SQR report programs
running as part of a real-time data collection and distribution
system. A sample report program using some of the library
functions is presented after the library code in the sample.

This script looks up ports in the services file, reads a config
file, and starts, stops, and checks/restarts UNIX processes.
