Did your webcam come with a CD/DVD containing an API for the camera?

Got the Solution!!!

Place an activeX control in the form
right click on it and select insert object
select kodak image scan control.
From the program menu import the ole library inerfaces for the kodak image scan control.
place an image item on the form to which the scanned image is to be displayed.This item should be a database item of type long raw.
in when_button_pressed trigger of a button write the code

:global.x:=:item('identity_pass.ACTIVEX_CONTROL10').interface;
Imaging_DImgScan.FileType(:global.x, 3);
Imaging_DImgScan.Image(:global.x, 'C:\album\123.bmp');
:global.a:=Imaging_DImgScan.OpenScanner(:global.x);
:global.c:=Imaging_DImgScan.StartScan(:global.x);
:global.d:=Imaging_DImgScan.StopScan(:global.x);
:global.e:=Imaging_DImgScan.CloseScanner(:global.x);

READ_IMAGE_FILE('C:\album\123.bmp','BMP', 'identity_pass.photo');

this will display the image and then save to store the image in the oracle database.

I repeat "Did your webcam come with a CD/DVD containing an API for the camera?"

Read the 'webutil' documentation with specific attention to the 'api' area.

Hello,

if you would allow me, how do you work-around the active-x component in a platform-independant perspective?

regards,
Didier

David doesn't visit this forum regularly any more, so ... don't hold your breath.

As of me - sorry, I wouldn't know how to do that.
