Re: [SyncEvolution] sqlite backend enhancement
Hi Lukas
Thanks for the response. I followed your tips but It didn't work here is my
code :
*TSyError res = this->ui.GetValueByID(this,**
*
* aItemKey,**
** valueId,
**
** ** **idx,**
** ** **sysync::VALTYPE_BUF,**
** ** **NULL,**
** ** **0,**
** ** **&valsize**
** ** **);**
** if(!res && valsize){**
** ** **data = SharedBuffer(new
char[valsize*1024*1024 + 1], valsize);**
** ** **data[valsize] = 0;**
** ** **res = this->ui.GetValueByID(this,**
** ** ** **
aItemKey,**
** ** ** **
valueId,**
** ** ** **
idx,*
*
sysync::VALTYPE_BUF,
data.get(),
valsize +
1,
&valsize
);
}*
I ve got size = 2759 but i always extract 4 bytes.
Can you help me please?
Thank you in advance

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
