Is there any idea of how to get a block preview in VB/VBA automation?
I'm thinking; once AutoCAD has that small preview image in block definition
dialog box, there should be a way to get exact same functionality in VB/VBA
automation (or I'm wrong). In general I'm looking some ocx/dll ready
component for this purpose.
(I found out that ObjectDCL uses built in BlockView control. Where they
fount it?)

One more think:
The same BlockView control used in ADT2i drawing/block preview pane.

run it.

Right click on the vbaide toolbox and select Additional Controls. Check AcPriview.ocx.

Not me personally. You might find some if you seach this ng for "AcPreview".

AcPreview1.Preview = "C:\Drawing1.dwg"

Now, anyone know why this doesn't work in VB6 or .NET?

According the knowledge base in the Autodesk developers section, the only way is to use blockicon with sendcommand (as Alfred stated above).

thanks for your help, but
I was thinking of previewing the icons
in a acPreview image window in a form,
not creating them...

Notice that link specifies "creating" a preview image. The AcPreview control is for viewing them. You pass it the filename and the control takes care of reading the bitmap stored in the dwg file header. The BLOCKICON command is useful for dwgs that have a bunch of blocks in them for use with Design Center, creating a priview for each block. Merely saving a dwg creates the preview for a file.

I found very useful
aced.com offered tools to preview drawing
and/or block bitmap image. <vlax.cls> and <ImageView.cls> do
everything.

The only problem I found was, that the
Vlisp object (used for retrieving dxf group code 310 chunks for saved bitmap
information) does work only in active(OPENED) drawing. So I couldn't get a
block image preview from CLOSED drawing. I'm trying to use ObjectDBX
to get entity data from CLOSED drawing, so far no success...

Thanks anyway to
aced.com guys and their supporters for
these VERY useful codes.

just looking for a sample code using acPreview
to display blockicons...
also, as "kidcoach" mentioned earlier,
how come it does not work in VB6?
thanks

No one ever said it didn't work in VB6 or .NET. Read Ed's message
again...the control is for VIEWING not for CREATING previews. To VIEW
the preview, the file has to have been saved using 2000i or better. 2000
had an option to not save previews.

So, kidcoach's problem is either that he did not issue a .Refresh after
telling the control which file to preview, or he was accessing a pre-
2000i file, or had a blank drawing with no geometry which won't preview
either.

Look in this ng for "Help w/ Drawing Explorer ActiveX control" as I
posted sample code for using the control.

thanks for your answer..
I would have liked a sample in acPreview,
and block icons.
DwgThumbnail works fine, it is the
acPreview which will not work in VB6,
although same code will work in VBA,
test it yourself and you will see...

Awh! I hate whenever I do that!!! My apologies to you and kidcoach.
While I saw acPreview, I read DwgThumbNail. Sorry.

To answer your question, my understanding is that acPreview is
intertwined with AutoCAD's Today dialog box. So it stands to reason that
it requires acToday.arx to be loaded - which is why it works in vba but
not vb.

Mike
