1) Ray Mercer's EZVidCap.
2) Pray the camera is TWAIN-compliant.
3) DirectShow.

The relative merits of each method are specific to your application,
so other than the above list, it's back in your hands now. I can dig
further for more specific links if need be, but Google is your friend.
Well, except for the fact that they eventually want to own your
thoughts, that is. :)

Ray Mercer's EZVidCap is not stable.
For that reason I had somebody create an ActiveX-Control for me (it's
written in C++, uses DirectShow and is ATL).
It's absolutely stable, you can adjust cam size by code and even get the
DIB section. If you like I can ask him if he wants to license it for
you. I don't know the price, but I guess it would be around $100-150.
Well invested money, because you won't have any problems with crashes.

Cheers,
Tom

I had no idea about it not being stable. Could you elaborate?

I've been using it for years, and the only instability I've found is
when using certain, specific, codecs. Those codecs tend to bomb all
host apps, so maybe it's that?

I don't know anymore because it's been so long. I only remember that I
spent months trying to fix errors together with other coders. I wanted
it to be a stable as AMCAP and be able to iterate through all cameras,
set settings & so on. Ah, and I think I do remember that there were some
window problems where you had a special window that could not really be
controlled, maybe you know that better than I do.
I am using my control in a software that people pay for, so I could not
accept any flaws.

Cheers,
Tom.

Mr. Weber,

I might be interested in this. I'm trying to put together a database for a
small non-profit homeless shelter.

I'm more or less putting this together as an 'amatuer' - meaning that I have
considerable computer skills but no real programming background. I've put
the database together from scratch, learning as I go. If putting the
following together would be somewhat "intuitive", I believe I could put it
together.

Here's my goal:

On a form with basic guest information like First Name, Last Name, SSN, etc.
We would like to have a guest photo on that form as well. We would get that
image as a guest checks in from a webcam. Considering that almost all the
people using the database have very elementary computer skills, I need to
make capturing this image as easy as humanly possible. I want something
similar to WIA that can connect to a webcam or scanner by default (so they
don't have to select it and "acquire") and display the WIA form and then when
they click "Get Picture" it goes directly into the form and saves it as a
link to wherever we would tell WIA to save it?

So, basically, from the form, I want it to look like this:

Guest comes in. Guest stands in front of the webcam. User clicks "Get
Guest Image" button on the Access form. WIA form pops up. User clicks
"Capture" when the image is right. User clicks the image they want. User
clicks "Get Picture". The WIA form closes. The link is saved in a table and
a box displays the image from the link.



Thanks again!

This ActiveX control maybe can be of interest, and there is a fully
functional trial version to test.

Take a look at wiautil.dll. You can download it from miscrosoft. It comes
with some working sample. Pretty simple to do.
It only works with XP sp1 or higher though. The camera that works for me
care Cannon A series. There may be other.
