Can anyone give me some direction as to how to use a command button to
open the Windows Image Acquisition form?
Also, does anyone have any code that will assign/insert the path of
the image you select into a table?
For instance, I'm familiar with the BLOB concept and/or external
linking to an image. I just don't know how to select an image in WIA
and automatically save the image and connect the link.
My end users are not computer literate so I need to make this really
easy.
I've never used the "Windows Image Acquisition form", so can't help you
there. But the example apps allow the user to select an image file to use in
your database application.
The sample imaging databases at
http://accdevel.tripod.com illustrate three
approaches to handling images in Access, and the download includes an
article discussing considerations in choosing an approach. Two of the
approaches do not use OLE Objects and, thus, avoid the database bloat, and
some other problems, associated with images in OLE Objects.
If you are printing the images in reports, to avoid memory leakage, you
should also see MVP Stephen Lebans'
http://www.lebans.com/printfailures.htm.
PrintFailure.zip is an Access97 MDB containing a report that fails during
the Access formatting process prior to being spooled to the Printer Driver.
This MDB also contains code showing how to convert the contents of the Image
control to a Bitmap file prior to printing. This helps alleviate the "Out of
Memory" error that can popup when printing image intensive reports.
And, Stephen has an ActiveX control available that works in cases where the
graphics filters are not available -- and works better, I've heard, than the
OLE Object and OLE Controls.
Please note that there are other approaches, e.g.,
Application.FollowHyperlink, but those, like OLE and Bound OLE Frames still
leave you "at the mercy of the imaging software registered for the
filetype").
Finally, Access 2007 has enhancements that, reputedly, eliminate the
database bloat long associated with OLE Objects and Bound OLE Frames. But,
it still leaves you relying on the software registered for the image type,
which may not be as "cooperative" as we'd like in creating our display. It
also has the capability of having a variable number of Attachments to a
Record, which may be helpful. But, as I have not done much with it yet, I
certainly wouldn't suggest you rush out and replace an earlier version --
not until the first Service Pack, at least.
