Hello,
It is me again.
I have some troubles with PHOTO for synchronised contact.
I used the same idea to extract encoded value to decode it.
I tried with GetValue and GetValueByID but no chance.
Both should work (the PHOTO is not an array field).
Just pass VALTYPE_BUF as type, and provide a buffer large enough to get the binary photo
data.
To find out in advance how large the buffer needs to be, just call GetValue once with a
NULL pointer as buffer or zero buffer size. This will return the needed size in the
aValSize parameter, which you can use to allocate a buffer large enough to get the entire
PHOTO.
If you pass a buffer that is too small for the entire PHOTO data, you'll get
LOCERR_TRUNCATED status.
The data you get is binary data, usually a JPG. If you save the data 1:1 into a file, any
image viewer program should be able to show it.
Best Regards,
Lukas
