How do I move a file off of a Canon Camera

[oscarse]

I am going around in circles on this ... Canon has an sdk which allows us to capture the raw image and translate it to a jpeg on your PC ... but I want to take a number of pictures before I do the transfer ... the camera automatically makes jpegs and stores it to its memory cards ... on an XP machine XP connects the Camera as a device and at that point the files are treated like a normal folder with files in it. Searches through the internet reveal Canon is a TWAIN or WIA device but when I go to get these SDK's they are relating to getting raw images not files???

Does anyone know how I can link to the XP linked device and just use the dos move command to get these pictures? OR know what SDK I need to use to move these files off the camera

Are you trying to do this with Access and VBA?

 

[oscarse]

Yes I have already converted the current Canon SDK API for use with Access VBA ... now trying to find a way to get the stored pictures instead of transfering the raw images for each picture the way the SDK does it.

IF the camera can be seen as a drive in XP why not just use file objects in vba to copy the jpgs?

I wish it were seen as a drive ... it shows up under my computer as a Scanner/Camera but has folder like qualities ... doing a search for the unique files in those folders reveals nothing so I think XP is just linking this as an object ... what I would like to do is assign a drive to this object with the old dos subst but I would need a valid device name for the object.

If you go to "My Computer", doesn't the memory card show up as a drive with folders, similar to a USB flash drive or a Sony memory card?

No it doesn't show up that way it shows up as;
Name TYPE
Canon PowerShot A620 Digital Camera

Then if you click on that it provides a folder full of files

Like I said it would be so simple if it was a drive.

I am looking around with some systeminternals.com utilities to see if I can nail down what the OS is doing. When the camera power is turned on XP loads the WiaWizard but if I cancel that the process goes away ... the processviewer doesn't add any processes when I clickinto or copy a file from the camera to a disk folder so XP must have already defined this as a Folder object somewhere just need to find its name and or hWin handle to see if it can be substituted as a drive somehow and or find a way to use the file objects without defining a drive.
