names, then ‘bind’ an object based on that class to a COM

server. If the COM server raises an event that corresponds to a

method in the VFP host object, the VFP host object’s method

is called. For example, you could design a class with

.RecordChangeComplete() and .FieldChangeComplete() meth-

ods, instantiate it, then bind it to an ADO recordset. Your object

would then be alerted by ADO instantly whenever a field or

record in the recordset is changed.

To make the programmer’s life easier, vfpcom.d!l includes an

ExportEvents() method. You pass it the name of an existing

COM server object, and a program name:

oVfpcom = create(”vfpcom.comutll”)

oRS = create(”adodb.recordset”)

? oVfpCom.ExportEvents(0RS, “RSHandler.prg”)

This creates a program containing the skeleton code needed to

define a class with all the events raised by an ADO recordset.

Insert your code into the empty methods, instantiate the class,

and off you go.

Vfocom.dll comes with a very limited help file.

SlowStart (Con't from page 6)

some computers may need more or less than the default

timeout value. Note that, to avoid confusion when launching

FoxPro with the -t switch to supress the banner, use the full -

timeout argument when supplying a defferent SlowStart timeout.

Of course, some computers have absolutely no problem running

16 bit programs. In that case you don’t need SlowStart :-).

Release Notes

1.3 Sometimes program launching was not delayed and

SlowStart had no effect. Increased launch thread’s priority to fix

this under some circumstances.

1.1 Added support for full command line parameter passing.

Now SlowStart can be used without a shell LNK file.

1.0 Created. Enjoy!

Known Problems

1. SlowStart may have no affect on dual-processor systems.

Dual-processor computers divide the threads of execution

between CPUs when possible. This may bypass the mecha-

nism SlowStart uses to slow down the processor. Try using one

instance of SlowStart (or FoxStart) to launch another instance

of SlowStart (of FoxStart). Some people have had success with

this method.

2. In recent days, it has become apparent that SlowStart has no

effect on some single processor Pentium II machines. FoxStart

1.1 seems to work better in some cases.

[Ed. Note: Both S!owStart and its companion product,

Fox Start, are now available for downloading from the LA Fox

It Can’t Get Any Easier.......

We’ve come up with an easy way to submit articles to the LA

Fox DeveloperNewsietter one that has been overlooked for

a long time.

You can submit your articles to Barry Lee at CIS# 72723,3422

on Compuserve, orbrlee@earthlink.net.

These articles can be on any FoxPro-related topic, whether it

concerns a new technique you’ve discovered, a certain develop-

ment technique you may favor over others, book reviews, etc.

Editor reserves the right to edit or offer constructive comments

concerning submitted articles and accepted articles shall be

considered to be in the public domain.

The quality of this newsletter really depends on the members

that support it, not just read it. And I think we’d all be surpnsed

by the useful information that could be circulated around the

membership.

So.

How ‘bout it?
