Canon SDK & .NET

[Bill Yellin]

Greetings!
Trying to get the CANON Camera SDK to work with .Net - works well in
VB6, and Canon does say that they're not supporting .Net, but I've seen
messages out here from people who are working with it. So....

I took a working VB6 app and let the wizard convert it to .Net. When
execurint cdStartSDK, I get an 'unable to load dll' error. I've tried
putting the CDSDK.dll in the all folder levels of the app, with no
change.

Anyone working with this, how do you have it set up? I'm using
version 6.1.2 of the SDK.

Thanks, ......Bill

Do you have a reference to the dll in your project?

Chris

No. The dll can't be registered, and in their docs, Canon says that it
just has to be in the app folder. It works fine that way in VB6.

 

[Chris, Master of All Things Insignificant]

I wasn't asking if it was "registered". I asked if you added a reference to
it in your project. If you can't reference the dll in your project, then I
don't know how your would use it.

Sorry - I tried adding a reference and I'm told that it's 'not a valid
assembly or COM object'.

To use the canon sdk you have to reference the sdk by p/invoke methods,
using vs to translate the vb6 example to .net should provide you with a
starting point. I was working on transferring the vb6 example in the v6 sdk
to .net but gave up when they released v7 sdk. It was split into two
libraries for eos and the powershot series with no vb examples and only
support for C. They even mention that they have no plans in developing or
supporting a .net version, which seems a little stupid to me as most
compilers now seem to be for the .net framework.

Yeah, I've seen that note. That's why I'm using version 6.
Actually, I've gotten past the problem described above by putting the
dll in the app's \bin folder. I can now issue the cdStart SDK command,
and run through the enumeration of the attached cameras (only one, of
course) to fill in the Source_Info structure. Need this to issue the
cdOpenSource command, but it dies there, on a return code of 167772288.

Any ideas?

Stinks not having access to tech support or a decent debug source. The
manual just covers the commands, not errors.

Hi,

I have had luck with getting the canon camera sdk to work with
vb.net. Here is a sample in the got dot net web site that works.

Thanks, Ken - I'll check it out out Monday. (Not working tomorrow,
