Something Simple?

[Joe Caverly]

Hi,
I'm using PBCC 5.01.0100 on Windows XP.

I'm having difficulty in getting PBCC to use an ActiveXDLL that I created in Visual Basic 5.0.

The said DLL works fine from a VB program, and a Delphi program, so I know that the DLL is okay.

Here's the include file;

' Generated by: PowerBASIC COM Browser v.2.00.0070

' Library Name: myjlc
' Library File: C:\Documents and Settings\jlc\My Documents\Data\Visual Basic\myjlc\myjlc.dll
' Description :

' Version Dependent ProgID's
$PROGID_myjlc_cMathcMath = "myjlc.cMath"

' Class Indentifiers
$CLSID_myjlc_cMath = GUID$("{ED22822B-A2B3-4B4B-9D26-21FCE57D318A}")

' Interface Indentifiers
$IID_myjlc_Int__cMath = GUID$("{597360D2-FB5E-4ED3-9452-158898F40676}")

' Interface Name : Int__cMath
' Class Name : cMath
' ClassID : $CLSID_myjlc_cMath
Interface Int__cMath $IID_myjlc_Int__cMath
Inherit IDispatch

Method PricePerPound <1610809344> (ByRef In PricePerKg As Currency) As Currency
Method test <1610809345> ()
Method IsPrime <1610809346> (Byval number As Currency) As Integer
End Interface


Here's the PBTEST.BAS program,

#COMPILE EXE
#INCLUDE "myjlc.inc"

FUNCTION PBMAIN () AS LONG
DIM rc AS CURRENCY
DIM jlcutils AS Int__cMath
LET jlcutils = GETCOM "$CLSID_myjlc_cMath"
IF ISOBJECT(jlcutils) AND ISFALSE ERR THEN
PRINT "Success!"
rc = jlcutils.PricePerPound(4.54)
ELSE
PRINT "Error"
END IF
END FUNCTION

I have read "The Life and Times of an Object" at http://www.powerbasic.com/support/pb...ad.php?t=39898 but I must be missing something very simple.

Constructive assistance would be appreciated.

Thanks from Joe

Hi,
I should mention that the program just prints "Error", and ends.

If you are going to use the CLSID and not the ProgId use:

LET jlcutils = NEWCOM CLSID $CLSID_myjlc_cMath

or if you use the ProgID:

LET jlcutils = NEWCOM $PROGID_myjlc_cMathcMath

And you will want to use NEWCOM, see http://www.powerbasic.com/support/help/pbwin/html/LET_statement_(with_Objects).htm.

If the requested object is in a DLL (in-process server), you will always use the NEWCOM option, as you're asking for a new object.

Hi,
Thanks very much for the quick response.

Works like a charm.

And I was so sure the reason it didn't work was because you posted the code without Code Tags.
