Ya you can use Web Camera IDE as a container for taking the photo
use webutil_host if you are using oracle10g forms
if your are using forms 4.5 or 5.o then use host command to call the web cam ide.
the web cam ide is installed at the time of installing the web camera drivers.
Again you need to use timer for calling each image taken from camera
the camera is taking the photos in the my pictures quickcam images folder.
for this you need to use the dir/b c:\mypictures\quickcam\images >zz.txt
then use the text_io package to get the each and every file to read.
then remove all the files and use read_image_file with the parameters as received now from the text_io package
after opening the file zz.txt.
timer should be of 1000 mili seconds.
If you are not using 10g forms then directly camera application can be called in the ole/ocx container.
if not availabe then you can use VB to develop a OCX file and that can be used to perform the specified task.
