OLE example

[JD Kromkowski]

There seems to be a bug in the OLE example. The error is 21. So I think that the problem is that chartobjects isn’t getting created (it remains .nul) chartobjects =@ worksheet.getobject(property=”ChartObjects”, error=e) * chartobjects.callmethod(method=”Add”, 50, 90, 270, 150, error=e) e = 0 I don’t use Excel so I don’t know enough to sort out whether the problem is in Simpol or in how you tried to implement it. When I ran a record macro in Excel to do basically what you were trying to do I got this: Range(“C1:C5”).Select ActiveSheet.Shapes.AddChart.Select ActiveChart.SetSourceData Source:=Range(“‘Sheet1’!$C$1:$C$5”) ActiveChart.ChartType = xlColumnClustered Range(“B9”).Select Although, this http://support.microsoft.com/kb/142387 suggests something closer to what you were doing. oChart = oSheet.ChartObjects.Add(50, 40, 300, 200).Chart On the other hand your example is straight from the Superbase, REM This creates a chart embedded in the current sheet REM using the Excel default format s.Range(“C1:C5”).Select() s.Selection.Copy() s.ActiveSheet.ChartObjects.Add(50,90,270,150).Select() which does work.

Thanks for that. I just had a look, and it may for some strange reason
depend on the version of Excel, since this example works ok here using
Excel 2000. It may be any number of things. I don't think this is the
last word on the OLE2 stuff, but we will need a lot more data before we
can go further. We are just passing these calls off to wxWidgets
currently. The example will need to be corrected though to check for
success there then.

OK. I take it that there is no documentation for this, yet.

I tried to do OLE with WordPerfect.

I get warning

cannot get CLSID from ProgID

and error 529.

I don't know enough (since heretofore it was always easier to use DDE) to
know whether the trouble is me, or WP or Simpol.

The warning is pretty clear. You have supplied an object name that is
not able to be turned into a class ID. You would need to first do some
checking on using OLE2 with Word Perfect, to make sure the methodology
is even close to right.

I haven't documented that one (it is new) but I would guess it is a
general purpose OLE2 error.

At some stage we may have DDE client capability, but is simply not yet
high enough on the priority list.

I'm pretty sure it is correct. I can google for code as well as the next
fellow.

Try it then from Superbase, does it work? Or from Excel. The first step
is making sure it works at all. I have had no end of support calls when
I was at Superbase complaining that Superbase wasn't working, only to
discover the actual problem was not a part of Superbase at all, it would
turn out to be something totally unrelated, but because they were trying
it from Superbase, Superbase was broken.

Yes, this is the problem where is it broken?

First, am I doing something wrong. I've always use DDE rather OLE; so it
certainly could be me.

Second, I suppose if your OLE2Excel example worked without a hitch (as it
does is SB3); I would have presumed that I should first look for the
problem to be with WP. But as your OLE2Excel example didn't work
correctly. That puts Simpol into play as a source of problem.

Third, maybe the problem is on WP end.

If someone could get the Excel example working completely AND give an
example using some other application "WORD" maybe, then I would know that
I need to search for the problem within my capacities and/or with WP.

Possibly, though it may also be related to the version of Excel. When
run on my machine, the ole2excel sample runs flawlessly. That is part of
the problem. All this functionality does is give access to the OLE2
layer, but everything that you do using it is dependent on the product
that you are talking to. There are very definite limitations in the
wxWidgets OLE2 support (only supporting out-of-process servers – exe's
basically but not ActiveX controls).

This area tends to be full of experimentation, since it is not always
well documented in target products.

Until a number of people have done the experimentation, I can imagine it
will take some time.

This thread is musty, but I'll dip my oar in anyway.

I made a long and very detailed attempt to use OLE with Wordperfect from
Superbase a long time ago and finally gave it up; the OLE interface to
Wordperfect is broken (at least as recently as WP10) In fact, a lot of
WP10 was broken; I still use WP8 here, for those things I still use
Wordperfect for (mostly I use Open Office).

Wordperfect always worked fine with DDE. If DDE isn't supported in
simpol, I'll probably have to drop WP support.

Worst case, somebody could probably add basic DDE client support by
making API calls.
